[0032] The utility model provides an automatic molecular welding device.
[0033] Reference Figures 1 to 5 In one embodiment of the utility model, the automatic molecular welding equipment includes a welding machine body 10, a welding fixture 20 and a moving module 30; the welding fixture 20 includes a fixture body 21, a cover plate 22 and a rotating shaft 23, one side of the cover plate 22 is rotatably arranged on the fixture body 21 through the rotating shaft 23, so that the cover plate 22 can be rotated and switched between an open position and a closed position, and the cover plate 22 is used to press the workpiece to be welded placed on the fixture body 21, and the fixture body 21 is provided with a water-cooling flow channel and a liquid inlet 21a and a liquid outlet 21b respectively connected to the water-cooling flow channel, the liquid inlet 21a is suitable for communicating with the liquid outlet end of the cooling liquid supply device, and the liquid outlet 21b is suitable for communicating with the liquid return end of the cooling liquid supply device; the welding fixture 20 is arranged on the moving module 30, and the moving module 30 is used to drive the welding fixture 20 to move.
[0034] In this embodiment, the welding machine body 10 may include a welding power source, a welding controller, a welding electrode head, etc., which are not limited here.
[0035] The cooling principle is that the coolant flows from the liquid inlet 21a of the fixture body 21 into the water cooling channel, flows along the set flow path, and then flows out from the liquid outlet 21b. The coolant finally releases heat in the external chiller. During the cooling process, the product is cooled by heat conduction through the fixture body 21 after welding, the fixture body 21 and the internal coolant are cooled by heat conduction, and the cooling water is cooled by heat exchange in the chiller, realizing the cooling cycle of the entire product.
[0036] like Figure 5As shown, the liquid inlet 21a and the liquid outlet 21b of the fixture body 21 can be respectively provided with connection ports to facilitate the connection of the liquid supply pipe. To achieve a better heat dissipation effect, the fixture body 21 can be made of a material with good thermal conductivity, such as copper, etc., which is not limited here.
[0037] The moving module 30 may include at least one motion module, that is, it can drive the welding fixture 20 to move in at least one direction to facilitate loading and unloading.
[0038] It can be understood that during production, the material can be loaded manually or by a robot at the loading position, the product can be fixed in the welding fixture 20, and then the moving module 30 drives the welding fixture 20 to move to the welding position, and then it is welded. At the same time, the coolant is always flowing in the water-cooling flow channel of the welding fixture 20. The coolant takes away the heat generated by welding, so that the product is quickly cooled, and finally moved to the unloading position by the moving module 30. Obviously, the entire production process does not require manual operation or only requires a very small amount of manual operation, which greatly reduces the work intensity of the operator, effectively improves the automation degree of the welding equipment, and adopts the water-cooling circulation heat dissipation method to reduce waiting time and greatly improve production efficiency.
[0039] To further improve the automation of the welding equipment, further improve production efficiency, ensure welding quality, and ensure the safety of the welding process, please refer to Figure 3 and Figure 5 In one embodiment, the automatic molecular welding equipment may also include a controller electrically connected to the welding machine body 10 and the mobile module 30 respectively. A state sensor 24 for detecting the opening and closing state of the cover 22 is provided on the fixture body 21. The state sensor 24 is electrically connected to the controller. The controller is used to control the operation of the mobile module 30 according to the opening and closing state of the cover 22 detected by the state sensor 24.
[0040] In this embodiment, a state sensor 24 is configured on the welding jig 20 to monitor the opening and closing state of the cover 22 of the welding jig 20 in real time, and cooperate with the control system and the mobile module 30 to control the welding jig 20 to move forward and backward. The welding jig 20 is only allowed to move forward and perform welding operations when the cover 22 is in a closed state. This can prevent the welding jig 20 from colliding with the welding machine body 10 and being damaged.
[0041] In one embodiment, the welding machine body 10 may include a lifting module 11 and a welding head 12. The lifting module 11 includes an electric cylinder and a sliding guide rail driven by the electric cylinder. The welding head 12 is installed on a slider of the sliding guide rail. A pressure sensor electrically connected to the controller is provided on the outer end of the output shaft of the electric cylinder for detecting the welding pressure. The controller is also used to control the operation of the electric cylinder according to the welding pressure detected by the pressure sensor.
[0042] In this embodiment, the electric cylinder is equipped with a servo motor to provide pressure during welding. This pressure can be accurately controlled through the torque mode of the servo motor. Since a pressure sensor is installed at the end of the electric cylinder output shaft, real-time monitoring of the welding pressure can be achieved.
[0043] During the welding process, the torque control mode outputs pressure and the pressure sensor feeds back the real-time pressure value. The two data are compared and verified in real time in the control system. The actual welding pressure is adjusted in real time according to the comparison effect, that is, the welding pressure is increased or decreased, thereby ensuring the reliability of the welding pressure output.
[0044] Main reference Figure 3 In one embodiment, a temperature sensor may be provided on both sides of the welding machine body 10, respectively. The two temperature sensors are electrically connected to the controller and are used to detect the welding temperature. The controller is also used to control the operation of the welding head 12 according to the welding temperatures detected by the two temperature sensors.
[0045] In this embodiment, a non-contact temperature sensor can be installed on each of the left and right sides of the welding machine body 10. During welding, the two temperature sensors detect the welding temperature in real time. When the feedback difference between the two temperature sensors is controlled within a certain range (for example, 50°C), the temperature values sent back by the two temperature sensors are averaged, and the average value is compared with the control target temperature in real time. The welding current is adjusted in real time according to the comparison result, that is, the current is increased or decreased, thereby ensuring the reliability of the actual welding temperature of the product during the welding process, meeting the welding process requirements, and further improving the welding quality.
[0046] To further improve production efficiency, refer to Figures 1 to 4 In one embodiment, the movable module 30 may include an X-axis module 31, a Y-axis module 32 and a Z-axis module 33. The X-axis module 31 is arranged on the Z-axis module 33 through an auxiliary guide rail, and the Y-axis module 32 is arranged on the X-axis module 31. There are multiple Y-axis modules 32, and each of the multiple Y-axis modules 32 is installed on a welding fixture 20.
[0047] In this embodiment, there are preferably three Y-axis modules 32, and the three Y-axis modules 32 move forward and backward independently under the drive of their respective servo motors; the three Y-axis modules 32 are installed on the same X-axis module 31, and move left and right under the drive of the servo motor belonging to the X-axis module 31; and the X-axis module 31 is installed on the left and right auxiliary guide rails, and is driven by the servo motor belonging to the Z-axis module 33 to move up and down.
[0048] During welding, the three welding jigs 20 are welded alternately. While the product in each welding jig 20 is being welded, the products in the other two jigs can be in a cooling state. This ensures that the cooling time of each product is twice the welding time (including the mechanism alternating movement time), ensuring that the product has completed the cooling process when unloading, further reducing waiting time and helping to improve production efficiency.
[0049] To ensure the safety of operators, refer to Figures 1 to 3 In some embodiments, the automatic molecular welding equipment may further include a frame 40, on which the welding machine body 10, the welding fixture 20 and the moving module 30 may be installed, and a safety grating 50 electrically connected to the controller is provided on the frame 40.
[0050] Furthermore, in order to improve the safety of the automatic molecular welding equipment, in this embodiment, the Y-axis movement of the Y-axis module 32 is carried out in a two-stage control mode. The movement of the welding fixture 20 from the welding position to the safety grating 50 is the first stage of travel, and the movement of the welding fixture 20 from the safety grating 50 to the loading and unloading position is the second stage of travel. The movement speed of the Y-axis module 32 in the first stage of travel is greater than the movement speed in the second stage of travel. The movement speed of the Y-axis module 32 in the second stage of travel is 15 to 25 mm / s, preferably 20 mm / s, which is not limited here.
[0051] Preferably, the welding fixture 20 can move at the highest speed within the first travel range to achieve the fastest mechanism beat and improve production efficiency, while the welding fixture 20 can move at a low speed within the second travel range to maximize personnel safety.
[0052] In addition, in order to further improve the safety of the welding equipment and facilitate operators to view the production status in real time, refer to Figures 1 to 3 In some embodiments, at least one protective door 60 may be installed on the frame 40. The protective door 60 may be made of transparent materials such as glass and PMMA. An electromagnetic lock 61 is provided on the protective door 60 and the frame 40 to avoid accidental opening of the protective door 60 and ensure the safety of welding production.
[0053] The above description is only an optional embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
