Description

Technical Field

[0001] This application relates to the field of metal sheet processing technology, and in particular to an automatic welding machine for elastic metal sheets. Background Technology

[0002] Elastic metal sheets need to be soldered to terminals. In related technologies, manual soldering with soldering irons or resistance spot welding is generally used, which suffers from low efficiency and poor weld consistency. For example, when manually holding the elastic sheet, its inherent elasticity can easily lead to positioning deviations, and the welding temperature and pressure are entirely controlled by experience, easily resulting in incomplete soldering, over-soldering, or material deformation. Even with semi-automatic equipment, manual loading, unloading, and transfer of workpieces are still required, making the process cumbersome and prone to human error.

[0003] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this disclosure, and therefore may include information that does not constitute prior art known to those skilled in the art.

[0016] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0017] like Figures 1 to 4 As shown, one embodiment provides an automatic welding machine for flexible metal sheets, including: a welding device 100, a sheet feeding device 200, a terminal feeding device 300, and a handling robot 400.

[0018] The welding device 100 includes a support base, a drive cylinder 110, a movable base 120, a processing and bearing mechanism 130, a first welding mechanism 140, and a second welding mechanism 150. The drive cylinder 110 is mounted on the support base, and the movable base 120 is connected to the output end of the drive cylinder 110 and is movably disposed on the support base. The processing and bearing mechanism 130 is disposed on the support base, the first welding mechanism 140 is disposed at one end of the support base near the processing and bearing mechanism 130, and the second welding mechanism 150 is disposed on the movable base 120. A sheet feeding device 200 is located on one side of the welding device 100. A terminal feeding device 300 is located on one side of the welding device 100. A handling robot 400 is disposed on one side of the welding device 100 and is used to handle sheets and terminals onto the welding device 100.

[0019] In this embodiment, during operation, the automatic welding machine for flexible metal sheets activates the sheet feeding device 200 to prepare the metal sheet for feeding, and simultaneously activates the terminal feeding device 300 to prepare the terminal for feeding. The handling robot 400 activates, grabbing the metal sheet at the sheet feeding device 200 and simultaneously grabbing the terminal at the terminal feeding device 300. The grabbed metal sheet and terminal are then transported together to the processing support mechanism 130 of the welding device 100.

[0020] The welding device 100 is activated, and the drive cylinder 110 mounted on the support base pushes the movable seat 120, causing the movable seat 120 to move towards the processing support mechanism 130. This, in turn, moves the second welding mechanism 150 mounted on the movable seat 120 closer to the processing support mechanism 130. At this time, the first welding mechanism 140 located at the end of the support base near the processing support mechanism 130 cooperates with the moved second welding mechanism 150 to perform welding operations on the metal sheet and terminals on the processing support mechanism 130. After welding is completed, the handling robot 400 unloads the welded finished product.

[0021] This automatic welding machine for flexible metal sheets uses a transport robot 400 to load sheets and terminals into the welding device 100 in one go. Then, the first welding mechanism 140 and the second welding mechanism 150 simultaneously weld the sheets and terminals. This results in high product consistency and high welding efficiency.

[0022] like Figures 1 to 4As shown, in some embodiments, the processing support mechanism 130 includes a guide post 131, a sliding member 132, and a processing seat 133. There are two guide posts 131, which are respectively spaced apart on the support seat. The sliding member 132 is movably sleeved on the guide post 131. The processing seat 133 is fixed on the sliding member 132. The processing seat 133 has a communicating clearance groove 134 and a positioning groove 135. The clearance groove 134 is arranged along the width direction of the processing seat 133. The first welding mechanism 140 and the second welding mechanism 150 are arranged corresponding to the clearance groove 134. The positioning groove 135 is arranged along the length direction of the processing seat 133. A positioning post 136 is provided on the bottom wall of the positioning groove 135.

[0023] Positioning posts 136 are provided on the bottom wall of the positioning groove 135. It can be understood that there are four positioning posts 136, which are arranged at intervals. The width of the positioning groove 135 is approximately the same as the width of the sheet. In this way, the positioning groove 135 and the positioning posts 136 cooperate to achieve the positioning and limiting of the sheet, prevent the sheet from shifting during the welding process, and ensure the accurate position of the welding point.

[0024] The slider 132 is movably mounted on the guide post 131. It can be understood that the slider 132 can move along the length of the guide post 131, thus flexibly adjusting the position of the machining seat 133.

[0025] During operation, the handling robot 400 places the sheet in the positioning groove 135, and the positioning post 136 abuts against the edge of the sheet to achieve precise positioning and limiting of the sheet. Then, the handling robot 400 inserts the terminal into the middle position of the sheet. During welding, the welding pins of the first welding mechanism 140 and the second welding mechanism 150 extend from the opening of the clearance groove 134 and act directly on the welding point between the sheet and the terminal.

[0026] like Figures 1 to 4 As shown, in some embodiments, the first welding mechanism 140 includes a first mounting base and first welding pins. The first mounting base is fixed to a support base, and there are two first welding pins spaced apart on the first mounting base. Thus, the two first welding pins can weld two welding points on one side between the sheet and the terminal.

[0027] like Figures 1 to 4 As shown, in some embodiments, the second welding mechanism 150 includes a second mounting base and a second welding pin. The second mounting base is fixed to a support base, and there are two second welding pins spaced apart on the second mounting base. Thus, the two second welding pins can weld two welding points on one side of the sheet or terminal.

[0028] like Figures 1 to 4As shown, in some embodiments, the sheet feeding device 200 includes a sheet feeding mechanism 210 and a first pushing mechanism 220. The sheet feeding mechanism 210 is used to feed metal sheets, and the first pushing mechanism 220 is disposed on one side of the sheet feeding mechanism 210. The first pushing mechanism 220 is used to push out a metal sheet and wait for the handling robot 400 to pick it up.

[0029] The first pushing mechanism 220 may include a first pushing cylinder and a sliding member 132. The first pushing cylinder is located on one side of the sheet feeding mechanism 210, and the sliding member 132 is connected to the output end of the first pushing cylinder. The sliding member 132 is provided with a feeding groove that cooperates with the sheet feeding mechanism 210.

[0030] When the sheet feeding device 200 is working, the sheet feeding mechanism 210 arranges the stacked metal sheets in a preset posture and continuously conveys them to the feeding outlet, where they finally fall into the feeding trough. The first pushing mechanism 220 is activated, pushing the sliding member 132 toward the welding device 100. After the handling robot 400 picks up the sheet located in the feeding trough, the sliding member 132 is reset under the drive.

[0031] The sheet feeding mechanism 210 continuously feeds and the first pushing mechanism 220 pushes the sheet intermittently to ensure that the feeding process is uninterrupted and to provide a stable sheet input for the subsequent automated process.

[0032] like Figures 1 to 4 As shown, in some embodiments, the terminal feeding device 300 includes a terminal feeding mechanism 310 and a second pushing mechanism 320. The terminal feeding mechanism 310 is used for feeding terminals, and the second pushing mechanism 320 is disposed on one side of the terminal feeding mechanism 310. The second pushing mechanism 320 is used to push out a terminal and wait for the handling robot 400 to pick it up.

[0033] The terminal feeding mechanism 310 includes a first motor, a first lead screw transmission mechanism, and a moving plate. The second pushing mechanism 320 may include a second motor, a second lead screw transmission mechanism, and a toggle member. The first motor is located on one side of the support base, and the output end of the first motor is connected to the first lead screw transmission mechanism. The moving plate is fixed on the output end of the first lead screw transmission mechanism. The second motor is located on one side of the first motor, and the output end of the second motor is connected to the second lead screw transmission mechanism. The toggle member is connected to the output end of the second lead screw transmission mechanism, and the end of the toggle member is located above the moving plate.

[0034] The terminal material plate is placed on the moving plate. The first motor starts, and the moving plate is gradually moved towards the second lead screw drive mechanism via the first lead screw drive mechanism. In this way, the actuating component can enter each column of the terminal material plate, thereby pushing the terminals in each column closer to the terminal loading position, so that they can be gripped by the handling robot 400. The second motor starts, and the actuating component is moved towards the welding device 100 via the second lead screw drive mechanism, so that the actuating component can move along each column of the terminal material plate, thereby actuating the terminals closer to the terminal loading position.

[0035] like Figures 1 to 4 As shown, in some embodiments, the handling robot 400 includes a first linear cylinder 410, a second cylinder 420, a third cylinder 430, a suction mechanism 440, and a gripping mechanism 450. The first linear cylinder 410 is located on one side of the welding device 100 and has two output ends. The second cylinder 420 is mounted on one output end of the first linear cylinder 410. The suction mechanism 440 is located on the output end of the second cylinder 420. The third cylinder 430 is mounted on the other output end of the first linear cylinder 410. The gripping mechanism 450 is located on the output end of the third cylinder 430.

[0036] The suction mechanism 440 is located at the output end of the second cylinder 420. It is understood that the suction mechanism 440 may include two first suction nozzles.

[0037] The gripping mechanism 450 is disposed on the output end of the third cylinder 430. It can be understood that the gripping mechanism 450 may include a transfer cylinder, a connecting plate, and a gripper. The transfer cylinder is horizontally mounted on the output end of the third cylinder 430, the connecting plate is mounted on the output end of the transfer cylinder, and the gripper is mounted on the connecting plate. When the gripping mechanism 450 grips a terminal, the transfer cylinder pushes the transfer plate, causing the gripper to move above the terminal feeding device 300. The third cylinder 430 then drives the gripping mechanism 450 to move towards the terminal feeding device 300, causing the gripper to grip the terminal.
