[0003] Existing welding equipment includes a conveyor belt and a welding device. When the equipment is running, multiple objects to be welded are arranged on the conveyor belt in sequence; after the conveyor belt transports an object to the welding station, the conveyor belt stops running; after the welding device completes welding of the object, the conveyor belt continues to run, thereby moving the welded object out of the welding station and transporting the next object to the welding station.

[0054] Since the soft material is soft, it can be installed on the corresponding tooling before welding, and the tooling can be made of plastic sheets, etc. Among them, the first handling device, the position transfer device, the second handling device, etc. directly act on the tooling, thereby realizing the handling and transfer of the soft material.

[0055] Example

[0056] See also Figure 1-Figure 9 In this embodiment, a soft material welding device is proposed, comprising:

[0057] A first conveying device 100 is used to convey the soft material 800 to be welded;

[0058] The first transport device 200 is used to transport the soft material 800 on the first conveying device 100;

[0059] The workbench 300 is used to place the soft material 800 transported by the first transport device 200;

[0060] A welding device 400, used for welding the soft material 800 on the workbench 300;

[0061] The second transport device 500 is used to transport the welded soft material 800;

[0062] The second conveying device 600 is used to convey the soft material 800 conveyed by the second conveying device 500 .

[0063] like Figure 4 and Figure 5 As shown, a first recognition device 201 is provided on the first handling device 200, and a second recognition device 401 is provided on the welding device 400. Both the first recognition device 201 and the second recognition device 401 may include a camera device.

[0064] Each soft material 800 is provided with an identification code 801. The identification code 801 on the soft material 800 is an identification of the soft material 800, wherein the identification code 801 corresponds to the soft material 800 one by one. That is, each soft material 800 corresponds to a unique identification code 801. The identification code 801 may be a QR code, a bar code, etc. The identification code 801 may be printed on a paper label, wherein the paper label may be pasted on the outer surface of the soft material 800.

[0065] The first identification device 201 is used to read and record the identification code 801 on the soft material 800 transported by the first transport device 200 and generate first record data; the second identification device 401 is used to read and record the identification code 801 on the soft material 800 that has been welded and generate second record data.

[0066] Among them, the first recorded data and the second recorded data are compared every first preset time interval to determine whether there is any missed soft material 800: if there is an identification code 801 in the first recorded data that is not recorded in the second recorded data, and the interval between the time when the identification code 801 is recorded and the current time exceeds the first set time interval, it is determined that the soft material 800 corresponding to the identification code 801 is missed.

[0067] The time required for the soft material 800 to be transported by the first transport device 200 until the welding is completed is t1; the first preset time is t2, wherein t2>t1. t1 is related to the operating parameters of the equipment, and t2 needs to be adjusted according to t1.

[0068] In one embodiment, the device is in continuous operation. At the current moment, the first recorded data records six identification codes 801, which are respectively used for A, B, C, D, E and F. Since the time when any soft material 800 is welded is delayed from the time when the first handling device 200 handles it, at the current moment, the number of identification codes 801 recorded in the second recorded data must be less than or equal to six. For example, the second recorded data records four identification codes, which are A, B, C and E. Therefore, it can be seen that the identification codes 801D and F in the first recorded data are not recorded in the second recorded data.

[0069] The time when D is recorded in the first recorded data is T1, the time when F is recorded in the first recorded data is T2, and the current time is T0: the time difference between T0 and T1 is greater than t2, and the time difference between T0 and T2 is less than t2, so it can be determined that at the current time, the soft material 800 corresponding to the identification code 801D is omitted. The corresponding soft material 800 can be quickly found through the identification code 801D.

[0070] like Figure 2 As shown, in this embodiment, the spaces on both sides of the first conveying device 100 in the width direction are respectively the first side portion 101 and the second side portion 102, and the first side portion 101 and the second side portion 102 are both provided with a plurality of workbenches 300. The workbenches 300 located at the first side portion 101 and the second side portion 102 are sequentially arranged along the conveying direction of the first conveying device 100.

[0071] The first transport device 200, the welding device 400 and the second transport device 500 all correspond to the workbench 300. Specifically, each first transport device 200 corresponds to two workbench 300, each welding device 400 corresponds to one workbench 300, and each second transport device 500 corresponds to one workbench 300.

[0072] Reference Figure 2In this embodiment, the number of the first handling devices 200 located at the first side portion 101 is two, and the number of the first handling devices 200 located at the second side portion 102 is also two. The first handling devices 200 located at the first side portion 101 correspond to the workbench 300 (G1) and the workbench 300 (G2) on the same side, that is, the first handling devices 200 can carry the soft material 800 on the first conveying device 100 to the workbench 300 (G1) or the workbench 300 (G2); the first handling devices 200 located at the second side portion 102 correspond to the workbench 300 (G3) and the workbench 300 (G4) on the same side, that is, the first handling devices 200 can carry the soft material 800 on the first conveying device 100 to the workbench 300 (G3) or the workbench 300 (G4).

[0073] In other embodiments, the number of workbenches 300 located on the first side 101 and the second side 102 can also be set as needed. For example, the number of workbenches 300 located on the first side 101 and the second side 102 is four, six, eight or ten, etc.

[0074] like Figure 6 As shown, the first conveying device 100 includes a first conveying section 110 and a second conveying section 120, wherein the first conveying section 110 and the second conveying section 120 are sequentially arranged along the conveying direction of the first conveying device 100. The direction indicated by the arrow in the figure is parallel to the conveying direction of the first conveying device 100.

[0075] A direction adjustment device 130 is provided between the first conveying section 110 and the second conveying section 120. The direction adjustment device 130 is used to adjust the soft material 800 that is about to enter the second conveying section 120 so that the placement direction of the soft material 800 corresponds to each workbench 300.

[0076] The direction adjusting device 130 adjusts the placement direction of the soft material 800 alternately to the first placement direction and the second placement direction. That is, after the soft material 800 passes through the direction adjusting device 130 and enters the second conveying section 120, along the conveying direction of the first conveying device 100, the soft material 800 on the second conveying section 120 is arranged in sequence in an alternating distribution manner in the first placement direction and the second placement direction.

[0077] The placement rule of the soft material 800 on the second conveying section 120 is as follows: when a certain soft material 800 is placed in the first placement direction when it is conveyed to the second conveying section 120, the next soft material 800 will be adjusted to the second placement direction by the direction adjusting device 130 (if the soft material 800 is already in the second placement direction, no adjustment is required); when a certain soft material 800 is placed in the second placement direction when it is conveyed to the second conveying section 120, the next soft material 800 will be adjusted to the first placement direction by the direction adjusting device 130 (if the soft material 800 is already in the first placement direction, no adjustment is required).

[0078] The first placement direction corresponds to the workbench 300 located at the first side portion 101, and the second placement direction corresponds to the workbench 300 located at the second side portion 102. Since the workbench 300 located at the first side portion 101 and the second side portion 102 are respectively placed on both sides of the first conveying device 100, it is necessary to adjust the placement direction of the soft material 800 in advance. When the soft material 800 is transported to the workbench 300 at the corresponding position, the part to be welded on the soft material 800 can be aligned with the welding device 400, ensuring that the welding device 400 can achieve accurate welding of the part to be welded.

[0079] Reference Figure 7 , multiple soft materials 800 are sequentially arranged on the second conveying section 120, and the dotted lines on the soft materials 800 in the figure represent the parts to be welded. Among them, from left to right, the first and third soft materials 800 are in the first placement direction, and the second and fourth soft materials 800 are in the second placement direction.

[0080] like Figure 6 As shown, in this embodiment, the first conveying device 100 includes two parallel and spaced chain belts 103 , wherein the direction regulating device 130 is located between the two chain belts 103 of the first conveying device 100 .

[0081] like Figure 8 As shown, the direction adjustment device 130 includes a support plate 131 , a lifting module 132 and a rotating module 133 .

[0082] The support plate 131 is horizontally arranged and installed on the top of the lifting module 132. The support plate 131 is used to support the soft material 800.

[0083] The lifting module 132 is used to drive the support plate 131 to rise and fall, so as to adjust the distance between the soft material 800 and the first conveying device 100. The lifting module 132 can be a device or mechanism that can achieve linear motion, such as a cylinder or an electric push rod.

[0084] The rotating module 133 is used to drive the lifting module 132 to rotate and drive the support plate 131 to rotate, so as to adjust the placement direction of the soft material 800 on the support plate 131 to the first placement direction or the second placement direction. The rotating module 133 can adopt a reduction box, wherein the rotating module 133 can be driven by a motor. The rotation axis of the support plate 131 is parallel to the vertical direction.

[0085] In this embodiment, the soft materials 800 to be welded may be placed on a tray 900 . Specifically, on the first conveying device 100 , each soft material 800 to be welded is placed on a corresponding tray 900 .

[0086] The soft material 800 to be welded is placed on a pallet 900 in advance, wherein the pallet 900 is placed on the first conveying section 110 of the first conveying device 100. Due to the static friction between the pallet 900 and the first conveying device 100, the pallet 900 will be translated under the drive of the first conveying device 100; when the position sensor detects that the pallet 900 moves to the top of the support plate 131, the first conveying device 100 stops running, and the lifting module 132 is activated and drives the support plate 131 to move upward by a preset distance, thereby lifting the pallet 900 and making the pallet 900 not in contact with the first conveying device 100; then, the soft material 800 on the pallet 900 is detected by the initial recognition device to read and record the identification code on the soft material 800 801, and detects the placement direction of the soft material 800 through the visual positioning module; then, based on the above-mentioned placement rules, the pallet 131 is driven to rotate through the rotating module 133, wherein, when the pallet 131 rotates, the tray 900 placed on the pallet 131 and the soft material 800 in the tray 900 rotate synchronously; when the placement direction of the soft material 800 is adjusted, the lifting module 132 is actuated and drives the pallet 131 to move downward a preset distance, at which time the pallet 900 is separated from the pallet 131, and the pallet 900 contacts the first conveying device 100 again; then, the first conveying device 100 starts to run, and conveys the soft material 800 located directly above the pallet 131 and with the adjusted placement direction to the second conveying section 120.

[0087] In this embodiment, an initial recognition device is disposed above the direction adjustment device 130, and the initial recognition device is used to read and record the identification code 801 on the soft material 800 on the direction adjustment device 130, and generate initial recording data. The initial recognition device is not shown in the drawings.

[0088] At every second preset time interval, the initial recorded data is compared with the first recorded data to determine whether there is any soft material 800 that has not been transported to the workbench 300: if there is an identification code 801 in the initial recorded data that is not recorded in the first recorded data, and the interval between the time when the identification code 801 is recorded and the current time exceeds the second set time interval, it is determined that the soft material 800 corresponding to the identification code 801 is omitted.

[0089] The time required for the soft material 800 to be transported from the starting end to the tail end of the first conveying device 100 is t3; the second preset time is t4, wherein t4>t3. t3 is related to the operating parameters of the equipment, and t4 may need to be adjusted according to t3.

[0090] In one embodiment, the device is in continuous operation. At the current moment, the initial recorded data records six identification codes 801, which are used to represent A, B, C, D, E, F and G respectively. Since the time when any soft object is transported to the tail end of the first transport device 100 is delayed from the time when the first transport device 200 transports it, at the current moment, the number of identification codes 801 recorded in the first recorded data must be less than or equal to six. For example, the first recorded data records five identification codes, which are A, B, C, E and F respectively. Therefore, it can be seen that the identification codes 801D and G in the initial recorded data are not recorded in the first recorded data.

[0091] The time when D is recorded in the initial recording data is T3, the time when F is recorded in the initial recording data is T4, and the current time is T0: the time difference between T0 and T3 is greater than t4, and the time difference between T0 and T4 is less than t4, so it can be determined that at the current time, the soft material 800 corresponding to the identification code 801D is omitted. The corresponding soft material 800 can be quickly found through the identification code 801D.

[0092] In this embodiment, both the initial recognition device and the first recognition device 201 include a visual positioning module, which is used to determine the placement direction of the soft material 800 based on the orientation of the identification code 801 on the soft material 800. The identification code 801 is set at the corner area of ​​the soft material 800.

[0093] The initial recognition device includes a camera device. The identification code 801 on the soft material 800 and the image of the soft material 800 can be obtained through the initial recognition device, wherein the image of the soft material 800 taken is compared with the pre-stored image, and the placement direction of the soft material 800 can be determined by the position of the identification code 801 on the image. Subsequently, based on the above-mentioned placement rules, the placement direction of the soft material 800 on the pallet 131 is adjusted by the direction adjustment device 130.

[0094] like Figure 4 As shown, the first handling device 200 includes a mechanical arm 210, and a first picking module 220 is disposed on the mechanical arm 210. The mechanical arm 210 is used to drive the first picking module 220 to adjust the position, and the first picking module 220 is used to pick up the soft material 800.

[0095] The robot arm 210 can drive the first picking module 220 to complete translation, lifting and other actions. The specific structure of the robot arm 210 can refer to the existing design and will not be repeated in this article.

[0096] The first picking module 220 includes a mounting frame 221 and a vacuum suction head 222 disposed on the mounting frame 221, wherein there are a plurality of vacuum suction heads 222 arranged in sequence along the length direction of the mounting frame 221. The vacuum suction head 222 is connected to a vacuum pump via a hose, wherein the hose and the vacuum pump are both shown in the drawings.

[0097] like Figure 5 As shown, the workbench 300 includes a waiting area 301 and a welding area 302 .

[0098] A position transfer device 310 is disposed on the workbench 300 , wherein a second picking module 320 is disposed on the position transfer device 310 .

[0099] The second picking module 320 is used to pick up the soft material 800.
