[0043] The embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present invention are described in detail below.

[0044] The following is for reference. Figures 1-10 Describes a welding apparatus 1 for a tray according to an embodiment of the present invention.

[0045] like Figure 1 and Figure 2 As shown, the tray welding device 1 according to an embodiment of the present invention includes: a workbench 10, a clamping assembly 20, and a heating assembly 30. The workbench 10 mainly serves a supporting function and can be used to install other components. The clamping assembly 20 mainly serves a clamping function and can be used to clamp the tray. The heating assembly 30 serves a heating function and can be used to preheat the tray. The heating assembly 30 can be configured as a heating plate.

[0046] like Figure 1 and Figure 2As shown, the clamping component 20 is disposed on the workbench 10 and is adapted to clamp the pallet. The heating component 30 is disposed on the workbench 10 and is adapted to preheat the pallet from below. The clamping component 20, installed on the workbench 10, is suitable for clamping the pallet, making operation more convenient, reducing worker intervention, lowering safety hazards, and achieving precise positioning. Furthermore, it ensures continuous heating of the pallet bottom plate, maintaining the pallet's dimensions. The heating component 30, also installed on the workbench 10, is adapted to preheat the pallet from below. This preheating allows for uniform heating of the pallet bottom plate, preventing pallet deformation.

[0047] Therefore, the clamping component 20 is set on the worktable 10. The clamping component 20 is suitable for clamping the pallet, which simplifies the operation, achieves accurate positioning of the pallet, and allows the bottom plate of the pallet to be continuously heated to ensure the size of the pallet. A heating component 30 is added. The heating component 30 is set on the worktable 10. The heating component 30 is suitable for preheating the pallet from below. At this time, the bottom plate of the pallet can be heated evenly, thereby preventing the pallet from deforming.

[0048] Specifically, the clamping component 20 is adapted to be interference-fitted with the inner wall of the pallet to clamp the pallet. The interference fit between the clamping component 20 and the inner wall of the pallet can clamp the pallet and reduce the welding deformation of the pallet during the welding process.

[0049] Among them, such as Figure 3 and Figure 4As shown, the workbench 10 includes a mounting base plate 100, and the clamping assembly 20 includes a first clamping assembly 200 and a second clamping assembly 201.

The first clamping component 200 is suitable for clamping the pallet in a first horizontal direction, and the second clamping component 201 is suitable for clamping the pallet in a second horizontal direction. The first horizontal direction and the second horizontal direction are perpendicular to each other. That is to say, the first clamping component 200 and the second clamping component 201 can clamp the pallet in two mutually perpendicular horizontal directions. At this time, the pallet can be positioned in the horizontal direction, which simplifies the operation and achieves accurate positioning of the pallet.

[0050] In addition, such as Figure 3 As shown, the first clamping assembly 200 includes: a first fixing member 202, a first driving member 203 and a first clamping member 204.

The second clamping member 208 is connected to the connecting rod assembly 207. At this time, the operation of the second drive member 206 can drive the operation of the second clamping member 208, thereby realizing the second clamping assembly 201 to clamp the pallet in the second horizontal direction to achieve the positioning of the pallet. The second drive member 206 can be set as a cylinder.

[0052] Furthermore, such as Figure 4 As shown, the linkage assembly 207 includes: a first linkage 209, a second linkage 210, a third linkage 211, a fourth linkage 212, a first mounting member 213, and a second mounting member 214.

The fourth pressing member 231 is located at the lower part of the other end of the second rotating member 230. When the sixth driving member 228 works, it drives the second connecting member 229 to move. The second connecting member 229 drives the second rotating member 230 to rotate, and the second rotating member 230 drives the fourth pressing member 231 to press down, thereby realizing that the sixth pressing assembly 218 presses the tray from above. The sixth driving component 228 can be configured as a high-power clamping cylinder.

[0060] Optionally, such as Figure 5 and Figure 6 As shown, the clamping assembly 20 further includes a seventh clamping assembly 232, which is connected to the first slider 220. The seventh clamping assembly 232 includes a seventh driving member and a first hanging member 233. The seventh driving member and the first hanging member 233 drive each other, and the first hanging member 233 selectively hooks and engages with the mounting base plate 100. The seventh clamping component 232 can perform a clamping function and can be used to clamp the tray. The seventh clamping component 232 is connected to the first slider 220. The seventh clamping component 232 can move up and down with the first slider 220. The seventh driving component and the first hanging component 233 are components of the seventh clamping component 232. The seventh driving component can perform a driving function, and the first hanging component 233 can perform a hooking function. The seventh driving component and the first hanging component 233 drive each other. The first hanging component 233 selectively hooks and engages with the mounting base plate 100. The operation of the seventh driving component can drive the first hanging component 233 to move. The first hanging component 233 can hook onto the mounting base plate 100, which can further play a fixing role and prevent the first slider 220 and the fourth driving component 223 from sliding downward.

[0061] like Figure 7 and Figure 8As shown, the eighth clamping assembly 234 is connected to the second slider 222. The eighth clamping assembly 234 includes an eighth driving member and a second hanging member 235. The eighth driving member and the second hanging member 235 drive each other, and the second hanging member 235 selectively hooks and engages with the mounting base plate 100. The eighth clamping assembly 234 can perform a clamping function and can be used to clamp the tray. The eighth clamping assembly 234 is connected to the second slider 222. The eighth clamping assembly 234 can move up and down with the second slider 222. The eighth driving member and the second hanging member 235 are components of the eighth clamping assembly 234. The eighth driving member can perform a driving function, and the second hanging member 235 can perform a hooking function. The eighth driving member and the second hanging member 235 drive each other. The second hanging member 235 selectively hooks and engages with the mounting base plate 100. The operation of the eighth driving member can drive the second hanging member 235 to move. The second hanging member 235 can hook onto the mounting base plate 100, which can further fix it and prevent the second slider 222 and the sixth driving member 228 from sliding downward.

[0062] Specifically, such as Figure 9 and Figure 10 As shown, the clamping assembly 20 further includes a ninth clamping assembly 236 and a tenth clamping assembly 237. The ninth clamping assembly 236 is located above the worktable 10 to clamp the pallet from above, and the tenth clamping assembly 237 is located in the middle of the worktable 10 to clamp the pallet from the middle. The ninth clamping assembly 236 and the tenth clamping assembly 237 are components of the clamping assembly 20 and both can perform clamping functions to clamp the pallet. The ninth clamping assembly 236 is located above the worktable 10 to clamp the pallet from above. The tenth clamping assembly 237 is located in the middle of the worktable 10 to clamp the pallet from the middle, thus preventing the pallet from bulging in the middle.

[0063] Among them, such as Figure 9As shown, the ninth clamping assembly 236 includes multiple ninth driving elements 238 and multiple fifth clamping elements 239, with each of the ninth driving elements 238 and the multiple fifth clamping elements 239 driving and engaging in a one-to-one correspondence. The multiple ninth driving elements 238 and the multiple fifth clamping elements 239 are components of the ninth clamping assembly 236. The ninth driving elements 238 provide a driving function, while the fifth clamping elements 239 are mainly used to clamp the pallet. The one-to-one driving and engaging of the multiple ninth driving elements 238 and the multiple fifth clamping elements 239 ensures that the pallet bottom plate is continuously compressed and evenly heated. This allows the compressive stress on the pallet bottom plate during welding to be continuously released, preventing stress residue. After welding, the even distribution of heat reduces compressive stress and plastic shrinkage, ultimately improving the welding deformation of the pallet, ensuring the pallet flatness meets product requirements, and preventing further deformation due to residual stress release during later use. The multiple ninth driving elements 238 can be configured as cylinders.

[0064] In addition, such as Figure 9 As shown, the ninth clamping assembly 236 also includes a fixed hook 240. The fifth clamping member 239 is provided with a lifting lug 241, and the fixed hook 240 selectively engages with the lifting lug 241. The fixed hook 240 can be used to hook other components, and the lifting lug 241 facilitates lifting operations. The fixed hook 240 selectively engages with the lifting lug 241; that is, after the pallet is welded, when multiple ninth driving components 238 retract multiple fifth clamping members 239, the fixed hook 240 engages with the lifting lug 241, preventing the fifth clamping member 239 from falling.

[0065] Of course, such as Figure 10As shown, the tenth clamping assembly 237 includes: a tenth driving member 242, a third connecting member 243, a third rotating member 244, a second supporting member 245, and a sixth clamping member 246. One end of the third connecting member 243 is connected to the driving part of the tenth driving member 242, and the other end of the third connecting member 243 is hinged to one end of the third rotating member 244. One end of the second supporting member 245 is hinged to the middle part of the third rotating member 244, and the sixth clamping member 246 is disposed at the lower part of the other end of the third rotating member 244. The tenth driving member 242, the third connecting member 243, the third rotating member 244, the second supporting member 245, and the sixth clamping member 246 are components of the tenth clamping assembly 237. The tenth driving member 242 mainly functions as a drive, the third connecting member 243 functions as a connector, the third rotating member 244 can rotate, the second supporting member 245 functions as a support, and the sixth clamping member 246 is mainly used to clamp the tray. One end of the third connecting member 243 is connected to the driving part of the tenth driving member 242, and the other end of the third connecting member 243 is hinged to one end of the third rotating member 244. The two ends of the third connecting member 243 are respectively connected to the tenth driving member 242. The tenth driving member 242 and the third rotating member 244 are connected. One end of the second support member 245 is hinged to the middle of the third rotating member 244, providing support for the third rotating member 244. The sixth pressing member 246 is located at the lower part of the other end of the third rotating member 244. When the tenth driving member 242 operates, it drives the third connecting member 243 to move. The third connecting member 243 drives the third rotating member 244 to rotate, and the third rotating member 244 drives the sixth pressing member 246 to press down, thereby enabling the tenth pressing assembly 237 to press the tray from the middle. The tenth driving member 242 can be configured as a cylinder.

[0066] Furthermore, the tray welding device 1 also includes a sensing component disposed on the clamping component 20. The sensing component can detect various physical or chemical quantities in the environment and convert this information into electrical signals for use by the control system or other equipment. Distributed on the clamping component 20, the sensing component can determine whether the tray is properly positioned. The sensing component can be configured as a magnetic induction device and can be mounted on the first driving member 203, the second driving member 206, the third driving member 219, the fourth driving member 223, the ninth driving member 238, and the tenth driving member 242.

[0067] In addition, such as Figure 1 and Figure 2As shown, the welding device 1 for the tray further includes a switch assembly 40 and a control assembly 50. The clamping assembly 20, the heating assembly 30, and the switch assembly 40 are electrically connected to the control assembly 50. The switch assembly 40 can be used to control the on / off state of the circuit, and the control assembly 50 can play a control role. The clamping assembly 20, the heating assembly 30, and the switch assembly 40 are electrically connected to the control assembly 50, so the control assembly 50 can control the clamping assembly 20, the heating assembly 30, and the switch assembly 40. It should be noted that the switch assembly 40 includes a first control switch and a second control switch. The first control switch consists of a first button, a second button, a third button, and a fourth button. The second control switch consists of a fifth button and a sixth button. The first and fourth buttons control the clamping and positioning action of the clamping assembly 20. The second button is a single-step retraction button, and the third button is a part removal button. After the tray welding is completed, pressing and holding the third button for three seconds will open all clamping assemblies 20. When clamping assemblies 20, the first and fourth buttons must be pressed simultaneously. When operating the ninth clamping assembly 236, the fifth and sixth buttons, as well as the first and fourth buttons, must be pressed simultaneously to achieve its downward action. The second button is for the clamping assembly 20 to achieve a single-step retraction function in case of an accident during loading. In addition, an emergency stop switch is added. Pressing the emergency stop switch will prevent the clamping assembly 20 from starting, which can prevent crushing accidents during personnel maintenance. The control assembly 50 can be set as a solenoid valve, and the interval between the actions of each solenoid valve can be set to one second.

[0068] It should be noted that, as Figure 2 As shown, the heating temperature of the heating component 30 is 'a', and the value of 'a' ranges from 150℃ to 180℃. It should be noted that the heating temperature 'a' of the heating component 30 needs to meet a certain range. Specifically, the heating temperature 'a' of the heating component 30 cannot be too low, that is, less than 150℃. If the temperature of the heating component 30 is too low, it will not be able to achieve the desired preheating effect on the tray, which will affect the uniform heating of the tray and may cause deformation. At the same time, the heating temperature 'a' of the heating component 30 cannot be too high, that is, greater than 180℃. If the heating temperature 'a' is too high, it will affect the preheating effect of the heating component 30 on the tray and may cause damage to the tray, resulting in deformation. Therefore, the heating temperature of the heating component 30 must meet a certain range, namely 150℃ to 180℃.

[0069] In addition, such as Figure 2As shown, the heating component 30 is constructed as a cast aluminum heating plate structure. Cast aluminum heating plate structures have good thermal conductivity, uniform heating effect, and high mechanical strength. By setting the heating component 30 as a cast aluminum heating plate structure, the heating component 30 is more in line with actual working conditions. In this way, the heating component 30 is suitable for preheating the pallet from below, which can make the bottom plate of the pallet evenly heated, thereby preventing the pallet from deforming.

[0070] The pallet according to the present invention is welded by the welding device 1 for the pallet described in the above embodiments.

[0071] Optionally, the tray is a rigid structural component welded by argon arc laser welding. Argon arc laser welding can provide high-quality, high-strength weld joints, making it suitable for manufacturing rigid structural components with high welding quality requirements. By setting the tray as a rigid structural component welded by argon arc laser welding, the tray possesses high strength and rigidity, as well as excellent welding performance and high welding quality, thus meeting practical needs.

[0072] The thickness of the pallet is denoted by b, and the value of b ranges from 0.8mm to 1.2mm. It should be noted that the pallet thickness b must meet certain requirements. Specifically, the pallet thickness b cannot be too small, i.e., less than 0.8mm. A thinner b would compromise the pallet's strength, hinder welding, and easily cause deformation. Conversely, the pallet thickness b cannot be too large, i.e., greater than 1.2mm. An excessively large b would increase the pallet's weight while maintaining weldability, hindering lightweight design and increasing costs. Therefore, the pallet thickness must adhere to a specific range, from 0.8mm to 1.2mm.
