For those skilled in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0054] Some embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0055] See also Figure 1 An embodiment of the present application provides a welding device 100, including a loading mechanism 10, an exhaust mechanism 20 and a welding mechanism 30. The welding device 100 is used for welding workpieces.

[0056] See also Figure 1 The loading mechanism 10 includes a loading part 11 and a cover part 12. The loading part 11 is provided with a receiving groove 111, and the receiving groove 111 is used to receive the workpiece. The cover part 12 is covered on the loading part 11 for sealing connection. The cover part 12 includes a first light-transmitting body 121. The exhaust mechanism 20 is spaced apart from the loading part 11 and is connected to the receiving groove 111. The exhaust mechanism 20 is used to evacuate the loading part 11 so as to form a vacuum environment in the sealed receiving groove 111. The welding mechanism 30 is provided on one side of the loading part 11. The welding mechanism 30 is used to emit a laser toward the workpiece in the vacuum environment in the loading mechanism 10. The laser is emitted to a preset position of the workpiece through the first light-transmitting body 121 to perform a welding operation. Exemplarily, the first light-transmitting body 121 can be any light-transmitting part, light-transmitting sheet or similar light-transmitting plate that can transmit laser light, such as a glass plate.

[0057] When the above-mentioned welding device 100 is actually used, the cover member 12 is opened on the loading member 11 that accommodates the workpiece to seal the accommodating groove 111, so that the accommodating groove 111 forms a sealed environment. The loading member 11 is vacuumed by the exhaust mechanism 20, so that the sealed accommodating groove 111 forms a vacuum environment, so that the welding mechanism 30 emits a laser toward the workpiece in the vacuum environment, so that the laser is emitted to the preset position of the workpiece through the first light-transmitting body 121 to laser weld the workpiece, thereby preventing the workpiece from being affected by the atmospheric environment, thereby improving the welding effect and yield.

[0058] See also Figure 2 and Figure 3In some embodiments, the cover member 12 further includes a cover body 122, a first sealing body 123, a first pressing body 124, and a connecting body 125. The cover body 122 is used to cover the loading member 11 and is provided with a mounting groove 1221 and a through groove 1222. The mounting groove 1221 is provided on the side of the cover body 122 facing away from the loading member 11. The mounting groove 1221 is used to receive the first light-transmitting body 121. The through groove 1222 is provided at the bottom of the mounting groove 1221 and is connected to the accommodating groove 111 when the cover body 122 is covered with the loading member 11. The first sealing body 123 is provided around the mounting groove 1221 and is embedded in the cover body 122. The first sealing body 123 abuts against the first light-transmitting body 121. The first pressing member 124 abuts the first light-transmitting member 121 and is detachably connected to the cover 122. The first pressing member 124 is provided with a relief groove 1241, which passes through the first pressing member 124 and corresponds to the through-groove 1222. The laser beam emitted by the welding mechanism 30 is directed to the workpiece via the relief groove 1241, the first light-transmitting member 121, and the through-groove 1222. A connecting member 125 is disposed on the outside of the cover 122 and is in communication with the through-groove 1222 and the exhaust mechanism 20, respectively.

[0059] In this manner, the first light-transmitting body 121 is received by the mounting groove 1221, and the through-groove 1222 is provided at the bottom of the mounting groove 1221, so that the mounting groove 1221 limits the mounting position of the first light-transmitting body 121, thereby ensuring that the laser emitted by the welding mechanism 30 is stably transmitted through the first light-transmitting body 121 and the through-groove 122 to the preset position of the workpiece. In addition, by providing the above-mentioned first sealing body 123, the first sealing body 123 seals the connection between the first light-transmitting body 121 and the cover body 122, thereby preventing the sealed receiving groove 111 from leaking from the connection between the cover body 122 and the first light-transmitting body 121. This further ensures the sealing stability of the cover member 12 and facilitates the vacuuming mechanism 20 to vacuum the receiving groove 111 connected to the through-groove 1222 through the connecting body 125. In addition, by setting the above-mentioned first clamping body 124, the first clamping body 124 presses the first light-transmitting body 121 to the cover body 122, so that the first light-transmitting body 121 remains in a stably installed state to avoid shaking during the workpiece welding process. At the same time, the avoidance groove 1241 opened in the first clamping body 124 avoids the laser emitted by the welding mechanism 30 to prevent the first clamping body 124 from blocking the laser.

[0060] See also Figure 1 and Figure 4In some embodiments, the vacuum mechanism 20 includes a vacuum pump 21, a connecting piece 22, a vacuum valve 23, and a vacuum release valve 24. The vacuum pump 21 is disposed on one side of the loading member 11. The connecting piece 22 is connected to the vacuum pump 21 and the connecting body 125, respectively. The vacuum pump 21 evacuates the loading member 11 via the connecting piece 22 and the connecting body 125. The vacuum valve 23 is connected to the vacuum pump 21 and the connecting piece 22, respectively. The vacuum valve 23 is used to control the opening or closing of the gas passage between the vacuum pump 21 and the connecting piece 22. The vacuum release valve 24 is connected to the connecting piece 22 and is used to control the opening or closing of the gas passage between the connecting piece 22 and the atmospheric environment. For example, the vacuum pump 21 can be a conventional commercially available vacuum pump 21. The connecting piece 22 can be any connecting portion, connecting pipe, or similar connecting rod capable of connecting the vacuum pump 21 and the connecting body 125, such as a plastic pipe. The vacuum valve 23 can be a vacuum valve, and the vacuum release valve 24 can be a vacuum breaker valve.

[0061] In this way, by setting the specific structure of the above-mentioned exhaust mechanism 20, after the cover part 12 is covered on the loading part 11, the through groove 1222 is connected with the accommodating groove 111, the vacuum valve 23 opens the gas passage between the vacuum pump 21 and the connecting part 22, and the vacuum release valve 24 closes the gas passage between the connecting part 22 and the atmospheric environment, so that the vacuum pump 21 evacuates the loading part 11 through the connecting part 22 and the connecting body 125, so that the accommodating groove 111 forms a vacuum environment, ensuring that the workpiece is welded in a vacuum environment, improving the welding effect and yield. After welding is completed, the vacuum valve 23 closes the gas passage between the vacuum pump 21 and the connecting part 22, and the vacuum release valve 24 opens the gas passage between the connecting part 22 and the atmospheric environment to release the vacuum environment of the accommodating groove 111, avoiding the cover part 12 from being unable to be removed from the loading part 11 under the action of negative pressure, thereby facilitating the removal of the welded workpiece.

[0062] See also Figure 1 、 Figure 5In some embodiments, the loading member 11 includes a second light-transmitting body 112, which is embedded in the bottom of the receiving groove 111 and corresponds to the first light-transmitting body 121. The welding device 100 also includes a conveying mechanism 40, which includes a first imaging member 41, a conveying member 42, and a sliding member 43. The first imaging member 41 is disposed below the welding mechanism 30 and is electrically connected to the welding mechanism 30. The conveying member 42 is disposed on one side of the welding mechanism 30. The sliding member 43 is connected to the conveying member 42 and has a through hole 431. The through hole 431 corresponds to the second light-transmitting body 112. The sliding member 43 is used to support the loading member 11 and, driven by the conveying member 42, drives the workpiece to move above the first imaging member 41, so that the first imaging member 41 captures an image of the workpiece through the through hole 431 and the second light-transmitting body 112. Exemplarily, the second light-transmitting body 112 can be any light-transmitting plate, light-transmitting sheet or similar light-transmitting block that can allow the first imaging component 41 to transmit light and capture images, such as a glass plate. The first imaging component 41 can be an industrial camera, and the conveying component 42 can be a servo slide.

[0063] In this way, the conveying member 42 drives the sliding member 43 to move the loading member 11 to the top of the first imaging member 41. The first imaging member 41 captures the image of the workpiece through the through hole 431 and the second light-transmitting body 112, and sends the acquired image information to the welding mechanism 30 through an electrical signal, so that the welding mechanism 30 determines the welding position 51 of the workpiece based on the image information of the workpiece, thereby ensuring that the welding mechanism 30 accurately welds the preset position of the workpiece.

[0064] See also Figure 1 In some embodiments, the welding device 100 further includes a substrate 50, a feeding mechanism 60, and a retrieving mechanism 70. The exhaust mechanism 20, the welding mechanism 30, the first imaging element 41, and the conveying member 42 are all disposed on the substrate 50. The substrate 50 is provided with a welding position 51 and a discharge position 52, and the first imaging element 41 is located at the welding position 51. The feeding mechanism 60 is disposed adjacent to the conveying member 42 and connected to the substrate 50. The feeding mechanism 60 is used to provide a workpiece. The retrieving mechanism 70 is disposed between the feeding mechanism 60 and the conveying member 42 and connected to the substrate 50. The retrieving mechanism 70 is used to transfer the workpiece from the feeding mechanism 60 to the loading member 11 located at the discharge position 52.

[0065] In this way, the workpiece to be welded is continuously provided by the feeding mechanism 60, so that the picking mechanism 70 transfers the workpiece from the feeding mechanism 60 to the loading part 11 located at the discharge position 52, so that the sliding part 43 stably drives the loading part 11 from the discharge position 52 to the welding position 51, making it convenient for the first imaging part 41 located at the welding position 51 to perform imaging operations on the workpiece.

[0066] See also Figure 1 and Figure 6In some embodiments, the conveying mechanism 40 further includes a second imaging element 44 . The second imaging element 44 is disposed at the discharge position 52 and connected to the substrate 50 . The second imaging element 44 is electrically connected to the retrieving mechanism 70 . The second imaging element 44 is configured to capture an image of the workpiece at the discharge position 52 through the through-hole 431 and the second light-transmitting body 112 for workpiece inspection. For example, the second imaging element 44 may be an industrial camera.

[0067] In this way, the image of the workpiece located at the discharge position 52 is captured by the second imaging element 44 through the through hole 431 and the second light-transmitting body 112, so as to detect the workpiece, determine whether the workpiece meets the standards, and determine whether the material-picking mechanism 70 places the workpiece to be welded on the loading part 11, thereby ensuring that the material-picking mechanism 70 stably places the workpiece in the receiving groove 111 of the loading part 11.

[0068] It can be understood that the above-mentioned compliance with the standard means that the preset area of ​​the workpiece has a preset feature, and the size of the preset feature is within a preset tolerance range, wherein the preset feature can be a protrusion, an inner hole, etc.

[0069] Please continue reading Figure 1 and Figure 6 In some embodiments, the welding device 100 further includes a temporary storage mechanism 80 , which is spaced apart from the conveying member 42 and connected to the substrate 50 . The temporary storage mechanism 80 is used to store workpieces that fail inspection.

[0070] In this way, the temporary storage mechanism 80 receives the workpieces that fail the inspection and stores the workpieces that fail the inspection, so as to facilitate centralized processing of the workpieces that fail the inspection.

[0071] It can be understood that the temporary storage mechanism 80 can also pre-store workpieces that have passed the inspection. In this way, when the material picking mechanism 70 places the workpieces that have failed the inspection on the temporary storage mechanism 80, the pre-stored workpieces that have passed the inspection can be taken away, and the workpieces that have passed the inspection can be added to the loading part 11 in a timely manner, avoiding repeated material picking and inspection, thereby shortening the welding process and improving welding efficiency.

[0072] See also Figure 1 and Figure 7 In some embodiments, the material picking mechanism 70 includes a transfer member 71, a material picking member 72, and a removal member 73. The transfer member 71 is connected to the substrate 50. The material picking member 72 is disposed on one side of the transfer member 71 and is connected to the transfer member 71. The material picking member 72 is used to remove the workpiece and place the workpiece in the receiving groove 111 under the drive of the transfer member 71. The removal member 73 is disposed on the other side of the transfer member 71 and is connected to the transfer member 71. The removal member 73 is used to remove the cover member 12 and, under the drive of the transfer member 71, cover the cover member 12 on the loading member 11. By way of example, the transfer member 71 can be a servo slide, a cylinder, or the like.

[0073] In this way, the material picking part 72 is moved by the feeding mechanism 60 to the loading part 11 located at the discharge position 52 under the drive of the transfer part 71 to place the workpiece in the receiving groove 111, and the removing part 73 is moved to the top of the loading part 11 under the drive of the transfer part 71 to cover the loading part 11 with the covering part 12, thereby quickly completing the loading operation of the workpiece and the sealing operation of the receiving groove 111, thereby improving production efficiency.

[0074] See also Figure 7 In this embodiment, the picking member 72 includes a lifting drive body 721 and a picking body 722. The lifting drive body 721 is connected to the transfer member 71, and the picking body 722 is connected to the lifting drive body 721. For example, the lifting drive body 721 can be a cylinder, and the picking body 722 can be any picking part, picking block, or similar picking claw capable of removing a workpiece, such as a clamping claw connected to the cylinder.

[0075] In this way, the lifting driving body 721 drives the picking member 72 to adjust the height of the picking member 722, so that the picking member 72 can stably remove the workpiece in the feeding mechanism 60 and stably place the workpiece in the receiving groove 111 of the loading member 11, thereby ensuring the stability of the workpiece removal.

[0076] It can be understood that the structure of the removing member 73 is substantially the same as that of the material taking member 72 , and the removing member 73 can stably place the covering member 12 on the loading member 11 or remove it.

[0077] See also Figure 5 and Figure 8 In some embodiments, the loading member 11 further includes a loading carrier 113, a second sealing member 114, a third sealing member 115, and a second pressing member 116. The receiving groove 111 is provided on the loading carrier 113. The loading carrier 113 further includes a seating groove 1131 and a connecting groove 1132. The seating groove 1131 is provided on a side of the loading carrier 113 facing away from the cover member 12 and is used to seat the second light-transmitting member 112. The connecting groove 1132 is provided at the bottom of the seating groove 1131 and is connected to the receiving groove 111. The second sealing member 114 is provided around the receiving groove 111 and embedded in the side of the loading carrier 113 facing the cover member 12. The second sealing member 114 is used to abut the cover member 12. The third sealing member 115 is provided around the seating groove 1131 and embedded in the loading carrier 113. The third sealing member 115 abuts the second light-transmitting member 112. The second pressing body 116 abuts against the side of the second light-transmitting body 112 away from the loading body 113 and is detachably connected to the loading body 113. The second pressing body 116 is provided with an avoidance groove 1161, which passes through the second pressing body 116 and corresponds to the connecting groove 1132. The first imaging component 41 photographs and images the workpiece through the through hole 431, the avoidance groove 1161, the second light-transmitting body 112 and the connecting groove 1132.

[0078] In this way, the second sealing body 114 abuts against the cover member 12 to seal the connection between the cover member 12 and the carrier 113, and the third sealing body 115 abuts against the second light-transmitting body 112 to seal the connection between the second light-transmitting body 112 and the carrier 113. This helps maintain the sealing of the accommodating groove 111 and prevents air leakage in the accommodating groove 111 during the laser welding process of the workpiece. In addition, by providing the above-mentioned second pressing body 116, the second pressing body 116 presses the second light-transmitting body 112 against the carrier 113 to keep the second light-transmitting body 112 in a stably installed state, preventing it from shaking during the workpiece welding process. At the same time, the avoidance groove 1161 formed in the second pressing body 116 can avoid the first imaging member 41, preventing the second pressing body 116 from blocking the imaging path of the first imaging member 41.

[0079] See also Figure 1 and Figure 9 In some embodiments, the welding mechanism 30 includes a welding member 31 and an adjusting member 32. The welding member 31 is disposed on one side of the loading member 11 and is configured to emit a laser toward the workpiece. The adjusting member 32 is connected to the welding member 31 and is configured to drive the welding member 31 toward or away from the loading member 11 to adjust the distance between the welding member 31 and the workpiece. For example, the welding member 31 can be any welding device capable of emitting a laser, and the adjusting member 32 can be a servo slide, a cylinder, or the like.

[0080] In this way, the distance between the welding member 31 and the workpiece is adjusted by the adjusting member 32 so that a moderate distance is maintained between the welding member 31 and the workpiece, thereby ensuring that the laser emitted by the welding member 31 stably welds the workpiece.

[0081] See also Figure 1 In some embodiments, there are multiple groups of loading mechanisms 10, and the exhaust mechanisms 20 are respectively connected to the multiple groups of loading mechanisms 10. There are multiple groups of welding mechanisms 30, and the multiple groups of welding mechanisms 30 correspond one-to-one to the multiple groups of loading mechanisms 10. In this way, the welding device 100 can perform welding operations on multiple workpieces at the same time, thereby improving production efficiency.

[0082] The working process of the welding device 100 is roughly as follows:

[0083] First, the feeding mechanism 60 provides the workpiece to be welded. The picker 72 removes the workpiece and, driven by the transfer member 71, places the workpiece into the receiving groove 111 of the loading member 11 located at the discharge position 52. The second imaging member 44 captures an image of the workpiece located at the discharge position 52 through the through hole 431 and the second light-transmitting body 112 to inspect the workpiece.

[0084] Then, the conveying member 42 drives the sliding member 43 to move the loading member 11 to above the first imaging member 41. The first imaging member 41 captures an image of the workpiece through the through hole 431 and the second light-transmitting body 112, and transmits the acquired image information to the welding mechanism 30 via an electrical signal, so that the welding mechanism 30 determines the welding position 51 of the workpiece based on the image information of the workpiece.

[0085] Finally, the removal member 73, driven by the transfer member 71, drives the cover member 12 to move to the top of the loading member 11, and covers the loading member 11 with the cover member 12 to seal the receiving groove 111, so that the receiving groove 111 forms a sealed environment. The loading member 11 is vacuumed by the exhaust mechanism 20, so that the sealed receiving groove 111 forms a vacuum environment, so that the welding mechanism 30 emits a laser toward the workpiece in the vacuum environment, so that the laser is emitted to the preset position of the workpiece through the first light-transmitting body 121 to laser weld the workpiece, thereby preventing the workpiece from being affected by the atmospheric environment, thereby improving the welding effect and yield.

[0086] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application and are not intended to limit the present application. Although the present application has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present application may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present application.
