[0045] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0046] Furthermore, reference numerals and / or reference letters may be repeated in different examples in this application. Such repetition is for simplification and clarity purposes and does not in itself indicate a relationship between the various embodiments and / or settings discussed. In addition, this application provides examples of various specific processes and materials; however, those skilled in the art will recognize the application of other processes and / or the use of other materials.

[0047] This application is described below with reference to the accompanying drawings and specific embodiments:

[0048] The welding operation of the cargo compartment door of the refrigerated truck requires welding the four sides of the door body. This usually requires the welder to operate the welding gun manually, which means that the welder needs to move within a relatively large working area and perform operations such as pressing and welding. The welding operation is complicated, labor-intensive, and the welding quality is unstable and the efficiency is not ideal.

[0049] Therefore, this application provides an automatic welding device for the cargo compartment door of an insulated truck, which aims to solve, to a certain extent, the technical problems of unstable welding quality and unsatisfactory welding operation efficiency of the weld seams around the cargo compartment door.

[0050] See Figure 1 , Figure 2 , Figure 3 and Figure 4 In some embodiments, the automatic welding device for the cargo compartment door of the insulated vehicle adopts an assembly line operation mode. Multiple welding stations are set up for the weld seams around the cargo compartment door 6. By moving the cargo compartment door 6 to multiple welding stations in an orderly manner, and then cooperating with the welding equipment on the welding stations, an orderly assembly line welding operation is achieved, thereby greatly improving the welding efficiency of the weld seams around the cargo compartment door 6, and relying on the advantages of automated mechanical welding to ensure welding quality.

[0051] Specifically, the automatic welding device for the cargo compartment door of the insulated vehicle includes a guide rail 1, a transport trolley 2, a first gantry welder 3, and a second gantry welder 4. The first gantry welder 3 and the second gantry welder 4 are spaced apart along the guide direction of the guide rail 1. The transport trolley 2 is movably mounted on the guide rail 1 and can move along the guide rail 1 to the working side of the first gantry welder 3 and the second gantry welder 4, thereby enabling the cargo compartment door 6 to be moved to the welding station of the first gantry welder 3 and the second gantry welder 4 for welding operation.

[0052] In order to accommodate the weld seams around the cargo door 6, the welding trajectory of the first gantry welding machine 3 can be configured as a first trajectory L, and the welding trajectory of the second gantry welding machine 4 can be configured as a second trajectory W. The first trajectory L and the second trajectory can be set along the weld seam shape around the cargo door 6, so as to completely realize the welding of the weld seams around the cargo door 6.

[0053] The automatic welding device for the cargo compartment door of the insulated truck provided in this application includes a guide rail, a transport trolley, a first gantry welding machine, and a second gantry welding machine. The first and second gantry welding machines are spaced apart along the guide rail to form two welding stations, welding two different areas. The transport trolley is movably mounted on the guide rail, moving the cargo compartment door along the guide rail to the two welding stations, thereby achieving assembly line operation and continuously completing automated welding operations on different areas of the cargo compartment door. This simplifies welding operations, improves overall welding efficiency, and enhances welding quality through automation.

[0054] In some embodiments, the guide rail 1 may be disposed below the first gantry welding machine 3 and the second gantry welding machine 4, and the transport trolley 2 may also pass below the first gantry welding machine 3 and the second gantry welding machine 4.

[0055] In some embodiments, the guide rail 1 may be configured as a linear guide rail, with the guiding direction being a straight line; the movement trajectory of the transport trolley 2 is a straight line trajectory.

[0056] In some embodiments, the guide rail 1 can be configured as a dual-rail system, which can improve the support stability of the transport trolley 2 to a certain extent and ensure the positioning accuracy of the transport trolley.

[0057] Correspondingly, the transport trolley 2 can also be configured with multiple sets of rollers 21, which are rolled on the guide rail 1; for example, four sets of rollers can be configured.

[0058] Generally, the transport vehicle 2 can be configured as a manually pushed vehicle or as an electrically driven vehicle.

[0059] In some embodiments, the automatic welding device for the cargo compartment door of the insulated vehicle may include an electric drive mechanism 5, which is connected to the transport trolley 2 and the guide rail 1 to drive the transport trolley 3 to move.

[0060] In some embodiments, the electric drive mechanism 5 may include a drive rack 51 and a drive motor 52. The drive rack 51 is disposed on the guide rail 1 along the guide direction of the guide rail 1. The drive motor 52 is disposed on the transport trolley 2, and a drive gear 521 is disposed on the output shaft of the drive motor 52. The drive gear 521 meshes with the drive rack 51, thereby enabling precise control of the movement distance of the transport trolley 2 by controlling the rotation of the drive motor 52, thereby controlling the transport trolley 2 to precisely stop at the welding station.

[0061] In some embodiments, the drive rack 51 may be disposed on the side wall of the guide slide rail 1, and the drive gear 521 may be disposed on the side of the guide slide rail 1, thereby avoiding vertical contact between the drive rack 51 and the drive gear 51, thus ensuring the smooth meshing and rolling of the drive gear 51.

[0062] In some embodiments, the guide rail 1 can be planned as a loading / unloading station, a first welding station and a second welding station according to actual needs, and corresponding parameters can be configured in the control host of the drive motor 52 to control the rotation direction and amplitude of the drive motor 52, thereby ensuring that the transport trolley 2 can be stably positioned at the loading / unloading station, the first welding station and the second welding station.

[0063] In some embodiments, position detection sensors may also be configured at the above-mentioned loading and unloading stations, the first welding station and the second welding station of the guide rail 1 to assist in positioning and ensure the positioning accuracy of the transport trolley 2.

[0064] In some embodiments, the transport trolley 2 can also directly control the rotation amplitude of the rollers of the transport trolley 2, thereby controlling the positioning accuracy of the transport trolley 2.

[0065] The roller assembly of the transport trolley 2 can be equipped with a roller motor to control the movement of the roller assembly.

[0066] In some embodiments, the first gantry welding machine 3 may include a first gantry support 31, a first welding carriage 32, and a first welding device 33. The first gantry support 31 may span across the guide rail 1. The first welding carriage 32 is movably mounted on the first gantry support 31. The first welding device 33 is mounted on the first welding carriage 32 to enable the welding device to move along the first trajectory L, perform continuous welding, and ensure the welding quality of the door weld.

[0067] Generally, the first gantry support 31 can be composed of two sets of gantry frames and beams connecting the two sets of gantry frames to form a frame to ensure the reliability of the overall support.

[0068] The first welding trolley 32 and the first welding equipment 33 can be integrated.

[0069] In some embodiments, in order to reduce the stability of the cargo door 6 during the welding process, the first gantry welding machine 3 may further include a first pressing mechanism 34, which is disposed on the first gantry bracket 31 to press the cargo door 6 onto the transport trolley 2.

[0070] Considering that the weld of the warehouse door 6 has a certain length, the first pressing mechanism 34 can press the warehouse door 6 along the first trajectory L to ensure the stability of the weld of the warehouse door 6 along the first trajectory direction and ensure the welding quality.

[0071] In some embodiments, the first pressing mechanism 34 may include a first pressing cylinder 341 and a first pressing member 342. The cylinder body of the first pressing cylinder 341 is disposed on the first gantry bracket 31, the cylinder rod is disposed on the first pressing member 342, and the first pressing member 342 may be configured to contact and press the regular workpiece of the cargo room door 6.

[0072] Generally, the first clamping member 342 can be configured as a plate-shaped member or a long strip-shaped member. The first clamping cylinder 341 and the first clamping member 342 can be configured in multiple ways, and the specific number can be set as needed.

[0073] In some embodiments, the welds around the cargo door 6 are approximately a regular square, i.e., two longitudinal and two transverse welds, totaling four welds. The first trajectory L and the second trajectory W can also be arranged along the longitudinal and transverse directions of the cargo door 6, i.e., the first trajectory L and the second trajectory W can be orthogonal or approximately orthogonal, allowing for a certain degree of deviation.

[0074] In some embodiments, the second gantry welding machine 4 may include a second gantry support 41, a second welding carriage 42, and a second welding device 43. The second gantry support 41 may span across the guide rail 1. The second welding carriage 42 is movably mounted on the second gantry support 41. The second welding device 43 is mounted on the second welding carriage 42 to enable the welding device to move along the second trajectory W, perform continuous welding, and ensure the welding quality of the weld seam of the cargo door 6.

[0075] Generally, the second gantry support 41 can be composed of two sets of gantry frames and beams connecting the two sets of gantry frames to form a frame to ensure the reliability of the overall support.

[0076] The second welding trolley 42 and the second welding equipment 43 can be integrated.

[0077] In some embodiments, in order to reduce the stability of the cargo door 6 during the welding process, the second gantry welding machine 4 may further include a second pressing mechanism 44, which is disposed on the second gantry bracket 41 to press the cargo door 6 onto the transport trolley 2.

[0078] Considering that the weld of the warehouse door 6 has a certain length, the second pressing mechanism 44 can press the warehouse door 6 along the second trajectory W to ensure the stability of the weld of the warehouse door 6 along the second trajectory direction and ensure the welding quality.

[0079] In some embodiments, the second pressing mechanism 44 may include a second pressing cylinder 441 and a second pressing member 442. The cylinder body of the second pressing cylinder 441 is disposed on the second gantry bracket 41, the cylinder rod is disposed on the second pressing member 442, and the second pressing member 442 may be configured to contact and press the regular workpiece of the cargo room door 6.

[0080] Generally, the second clamping member 442 can be configured as a plate-shaped member or a long strip-shaped member. The second clamping cylinder 441 and the second clamping member 442 can be configured in multiple ways, and the specific number can be set as needed.

[0081] It is worth noting that the accessories of the transport trolley 2, the first gantry welding machine 3 and the second gantry welding machine 4, such as cables and switch light components, can be adaptively set in appropriate positions and should have their usual setting positions, which will not be elaborated here.
