[0027] In the following description, a large number of specific details are provided to provide a more thorough understanding of the present invention. However, it is apparent to those skilled in the art that the present invention can be implemented without one or more of these details. In other examples, in order to avoid confusion with the present invention, some technical features well known in the art are not described.

[0028] like Figure 1 As shown, the present application provides an automatic processing, welding and quenching device for picks, including a quenching mechanism and an automatic welding robot.

[0029] In an embodiment, Figure 2As shown, the automatic welding robot 1 also includes a temperature measuring mechanism 2, which is mounted on the welding execution arm of the automatic welding robot 1. The temperature measuring mechanism 2 includes a detection disk 3, a detection seat 4, a laser thermometer 5 and a laser rangefinder 6. The detection disk 3 is rotatably arranged on the welding execution arm of the automatic welding robot 1, and the detection seat 4 is slidably arranged on the detection disk 3. The detection seat 4 moves along the axial direction of the detection disk 3. The laser thermometer 5 and the laser rangefinder 6 are both installed on the detection disk 3. The laser thermometer 5 and the laser rangefinder 6 are both located in front of the welding path of the automatic welding robot 1. After the welding path is changed, the detection disk 3 drives the laser thermometer 5 and the laser rangefinder 6. Rotate so that the laser thermometer 5 is always located in front of the welding path of the automatic welding robot 1 to detect the temperature of the welding position in real time, and the laser rangefinder 6 is always located in front of the walking path of the laser thermometer 5 to feedback the road conditions of the welding position in front of the laser thermometer 5 in real time, so as to adjust the measuring height of the laser thermometer 5 in time. The laser thermometer 5 is located between the laser rangefinder 6 and the welding head of the automatic welding robot 1. The detection height of the laser rangefinder 6 is greater than the detection height of the laser thermometer 5. It is necessary to ensure that the laser rangefinder 6 will not interfere with the highest position of the substrate protrusion, and ensure that the laser rangefinder 6 is always in normal working condition;At present, most of the temperature measuring mechanisms 2 have relatively simple structures and poor measurement accuracy. The temperature sensor is directly installed at the position corresponding to the welding head, so that the temperature sensor always faces the welding position for temperature measurement. However, the corresponding position of the welding head is in a welding state. Even if the temperature difference is detected, it is difficult to timely control the temperature of the welding position. Even if the temperature is controlled, it is easy to affect the welding work of the welding head, thereby directly affecting the welding quality. For this reason, the laser thermometer 5 is installed in front of the welding head of the automatic welding robot 1. Due to the different welding positions of different substrates, or when the welding position of the same substrate is nonlinear, the welding head will change the welding path. In order to ensure the laser thermometer 5 The optical thermometer 5 continues to measure the temperature right in front of the welding path, and a detection disk 3 is set. The rotation of the detection disk 3 drives the laser thermometer 5 to deflect around the welding head, so that the laser thermometer 5 can adapt to the changes in the welding path and make adjustments. Of course, the welding path is adjusted on the automatic welding robot 1 in advance, and the path can be directly read. Therefore, the rotation path of the detection disk 3 is set in advance according to the preset welding path of the automatic welding robot 1, so that the movement of the automatic welding robot 1 and the detection disk 3 are synchronized, and then the laser thermometer 5 can quickly and accurately locate the position right in front of the welding for temperature measurement, so that after detecting that the substrate temperature deviates from the preset welding temperature range, it can be timely The temperature of the position to be welded is adjusted, thereby reasonably changing the temperature measurement position of the substrate, thereby making the temperature measurement object more accurate. Secondly, since the automatic continuous welding is equipped with a cooling system, the setting of the cooling system will change the ambient temperature, thereby affecting the detection accuracy of the laser thermometer 5, and the farther the laser thermometer 5 is from the substrate, the worse its measurement accuracy is. Since the surface of most substrates is irregular, irregular welding is required. Therefore, the temperature measurement of the laser thermometer 5 at a close distance is easy to interfere with the substrate during the process. In order to ensure that the laser thermometer 5 set at a close distance will not interfere with the substrate, a laser rangefinder 6 is further set. The laser rangefinder 6 is used to measure the temperature of the laser thermometer 5 at a close distance. The laser thermometer 5 can detect the distance in front of the substrate, so as to simulate the shape of the welding position in advance, so that the laser thermometer 5 can make timely adjustments by lifting the detection seat 4 when it reaches the irregular welding position, so that the laser thermometer 5 can automatically avoid the irregular welding position in the substrate, and avoid interference with the substrate while ensuring a relatively close detection distance, so that the laser thermometer 5 can measure closer to the surface of the substrate, thereby improving the measurement accuracy; in specific implementation, the detection distance of the laser thermometer 5 is set according to the detection accuracy of the laser rangefinder 6, and under the detection accuracy of the laser rangefinder 6, the laser thermometer 5 is as close as possible to the welding surface of the substrate for temperature measurement, thereby further improving the temperature measurement accuracy. ;

[0030] In a further embodiment, Figure 5As shown, the detection disk 3 is rotatably connected to the execution arm of the automatic welding robot 1 through a bearing 7, a driving cavity 8 is provided in the detection disk 3, a hollow gear 9 is fixedly provided in the driving cavity 8, the hollow gear 9 is coaxially arranged with the execution arm of the automatic welding robot 1, and the hollow gear 9 is sleeved on the execution arm of the automatic welding robot 1 with a gap, a driving gear 10 is rotatably provided in the driving cavity 8, and the driving gear 10 is meshed with the hollow gear 9, a driving device is provided on the detection disk 3, and the driving device is used to drive the driving shaft of the driving gear 10 to rotate, and the driving device drives the driving shaft connected to the driving gear 10 to rotate, and the driving shaft drives the detection disk 3 to rotate on the execution arm of the automatic welding robot 1 through the meshing of the hollow gear 9 and the driving gear 10, and the detection disk 3 does not adopt a full circle rotation, and the forward rotation and the reverse rotation are combined to form a full circle, so as to avoid the detection disk 3 rotating in one direction for multiple times. The movable pillar 12 is slidably penetrated through the top of the fixed pillar 11, and the detection seat 4 is installed on the top of the movable pillar 12. A lead screw 13 is rotatably installed in the fixed pillar 11, and the movable pillar 12 is threadedly connected with the lead screw 13. The driving device is used to drive the lead screw 13 to rotate, and the driving device drives the lead screw 13 to rotate. Due to the sliding adaptation of the movable pillar 12 and the fixed pillar 11, the rotational freedom of the movable pillar 12 is limited, so that the movable pillar 12 moves along the axial direction of the lead screw 13, thereby driving the detection seat 4 to move, and then adjusting the detection position of the laser thermometer 5 and the laser rangefinder 6, the lead screw nut sub-mechanism is adopted to realize the lifting and lowering adjustment of the detection seat 4, which has a high movement accuracy, thereby matching the detection accuracy of the laser rangefinder 6.

[0031] Specifically, Figure 3 , Figure 4 and Figure 5As shown, the driving device includes a power switching housing 14 and a motor 15. A driving shaft 16 is rotatably arranged in the power switching housing 14. The motor 15 is installed on the top of the power switching housing 14. The output shaft of the motor 15 is connected to the motor shaft 40 through a coupling. The motor shaft 40 is rotatably connected to the power switching housing 14. A fourth bevel gear 41 is arranged on the motor shaft 40. A fifth bevel gear 42 is arranged on the driving shaft 16. The fifth bevel gear 42 is meshed with the fourth bevel gear 41. The motor 15 drives the motor shaft 40 to rotate. The motor shaft 40 drives the driving shaft 16 to rotate through the meshing of the fifth bevel gear 42 and the fourth bevel gear 41. Two chambers 17 are formed in the power switching housing 14 along the axial direction of the driving shaft 16. An electromagnetic transmission mechanism is arranged in the chamber 17. The structure is that a partition is fixedly arranged in the power switching housing 14, and the power switching housing 14 is divided into two independent chambers 17 by the partition, so that the electromagnetic transmission mechanisms in the two chambers 17 can operate independently without interfering with each other, and the driving shaft 16 is rotatably penetrated on the partition through the bearing, and there is a gap between the two ends of the transmission shaft 16 and the inner wall of the power switching housing 14. In order to ensure the stability of the driving shaft 16, a support seat can be further arranged in the chamber 17 to support the driving shaft 16. The electromagnetic transmission mechanism includes an electromagnetic coil 18, a magnetic disk 19 and a friction disk 20. The electromagnetic coil 18 is fixedly installed in the power switching housing 14, and the magnetic disk 19 is connected to the driving shaft 16 through a spline, so that when the driving shaft 16 rotates, the magnetic disk 19 is driven to rotate synchronously, and at the same time, the magnetic disk 19 is driven to rotate synchronously. The force disc 19 can also move along the axial direction of the driving shaft 16 to achieve contact or separation between the magnetic disc 19 and the friction disc 20. The friction disc 20 is rotatably arranged in the chamber 17. The friction disc 20 and the driving shaft 16 are clearance-matched. The magnetic disc 19 is located between the electromagnetic coil 18 and the friction disc 20. A friction pair is arranged on the side of the magnetic disc 19 close to the friction disc 20. The end of the friction disc 20 away from the magnetic disc 19 is connected with a hollow shaft 21. The hollow shaft 21 is rotatably connected to the power switching housing 14. One end of the hollow shaft 21 passes through the power switching housing 14 and is keyed to the first bevel gear 22. The first bevel gear 22 of one electromagnetic transmission mechanism is meshed with the second bevel gear 23 on the drive shaft, and the first bevel gear 22 of the other electromagnetic transmission mechanism is meshed with the third bevel gear on the lead screw 13. The gear 24 is meshed, and the two electromagnetic transmission mechanisms can operate separately or simultaneously. That is, when it is necessary to drive the lead screw 13 or the drive shaft to rotate, or when the lead screw 13 and the drive shaft are driven to rotate at the same time, the corresponding electromagnetic transmission mechanism is started to operate. Specifically, the electromagnetic coil 18 is energized to generate magnetism, and the magnetic poles of the electromagnetic coil 18 are the same as the magnetic poles of the magnetic disk 19. Therefore, after the electromagnetic coil 18 generates magnetism, it will repel the magnetic disk 19, so that the magnetic disk 19 moves close to the friction disk 20, and the friction pair of the magnetic disk 19 contacts the friction disk 20 to generate high-intensity friction, so that the magnetic disk 19 drives the friction disk 20 to rotate, and the friction disk 20 drives the hollow shaft 21 to rotate, and the hollow shaft 21 drives the drive shaft to rotate through the meshing of the first bevel gear 22 and the second bevel gear 23.Thus, the detection disk 3 is driven to rotate by the meshing of the driving gear 10 and the hollow gear 9, or the hollow shaft 21 drives the lead screw 13 to rotate through the meshing of the first bevel gear 22 and the third bevel gear 24, so as to realize the movement of the movable support 12 to adjust the detection height of the laser thermometer 5. When it is necessary to stop the rotation of the detection disk 3 or the movement of the detection seat 4, the electromagnetic coil 18 in the corresponding electromagnetic transmission mechanism is powered off, so that the electromagnetic coil 18 no longer generates a force on the magnetic disk 19, so that there is no high-intensity friction between the friction disk 20 and the magnetic disk 19, so that the magnetic disk 19 cannot drive the friction disk 20 to rotate, thereby cutting off the power transmission of the driving shaft 16 and stopping the corresponding movement.

[0032] As a preferred solution, Figure 4 As shown in FIG. 1 , although the magnetic disk 19 no longer clings to the friction disk 20 to generate high-intensity friction after the electromagnetic coil 18 is powered off, the contact between the magnetic disk 19 and the friction disk 20 still generates friction, which may slightly drive the hollow shaft 21 to rotate, thereby affecting the moving accuracy of the detection disk 3 and the detection seat 4. Therefore, when the electromagnetic coil 18 is powered off, it is necessary to

[0033] The magnetic disk 19 is separated from the friction disk 20 in time. For this purpose, the following structure is designed to realize the automatic reset of the magnetic disk 19. Specifically, a blocking disk 25 is fixedly mounted on the active shaft 16. The blocking disk 25 is located between the electromagnetic coil 18 and the magnetic disk 19. The diameter of the blocking disk 25 is smaller than the diameter of the magnetic disk 19. A plurality of reset springs 26 are connected between the blocking disk 25 and the magnetic disk 19. The plurality of reset springs 26 are evenly distributed around the center of the blocking disk 25. When the electromagnetic coil 18 is powered off and the reset spring 26 is in a normal state, the magnetic disk 19 is located between the electromagnetic coil 18 and the friction disk 20. Therefore, the reset spring 26 needs to be stretched to move the magnetic disk 19 close to the friction disk 20. Therefore, after the electromagnetic coil 18 is powered off, the magnetic disk 19 is restored to its original position under the reaction force of the reset spring 26, thereby timely cutting off the power output, ensuring that the detection disk 3 and the detection seat 4 have high motion accuracy to meet the measurement accuracy requirements of the laser thermometer 5 and the laser rangefinder 6.

[0034] In another embodiment, if Figure 5As shown, two cooling bodies 27 are arranged at intervals at the bottom of the detection disk 3, and the welding head of the automatic welding robot 1 is located between the two cooling bodies 27. A cooling cavity 28 is arranged in the cooling body 27, and a plurality of cold air outlets 29 are opened at the bottom of the cooling body 27 along its length direction. The cold air outlets 29 are communicated with the cooling cavity 28, and the cold air outlets 29 are arranged at an angle to the plane of the cooling body 27, and the high end to the low end of the cold air outlet 29 gradually moves away from the welding head of the automatic welding robot 1. When the laser thermometer 5 detects that the surface temperature of the substrate rises and deviates from the preset temperature range of welding, the cold air outlet 29 sprays cold air to the surface of the substrate to reduce the temperature of the surface of the substrate. In order to avoid the influence of cold air on welding, the cold air outlet 29 is opened toward a position away from welding so that the cold air can pass through the substrate. The air moves away from the welding position. On the one hand, it can avoid the cold air directly acting on the welding position and affecting the welding. On the other hand, the cold air can directly act in front of the welding position for cooling, so as to quickly cool the position to be welded, and can quickly reduce the surface temperature of the substrate to be welded, so as to more accurately and quickly reduce the surface temperature of the substrate, and effectively prevent the phenomenon of welding overheating. A cold air baffle 30 is fixed on the side of the cooling body 27 close to the automatic welding robot 1, and the bottom end of the cold air baffle 30 is located below the cooling body 27. The diffused cooling is blocked by the cold air baffle 30, and the amount of cold air flowing to the welding position is reduced. On the one hand, the welding position can be cooled, and on the other hand, the direct action of the cold air can be avoided to affect the welding.

[0035] Specifically, a cold air convection plate 31 is fixed on the side of the cooling body 27 away from the cold air baffle 30, and a cold air cavity 32 is opened in the cold air convection plate 31. A plurality of convection holes 33 are opened on the side of the cold air convection plate 31 close to the cooling body 27. The convection holes 33 are located above the cold air cavity 32 and are interconnected. The convection holes 33 correspond to the cold air outlets 29 one by one, and the convection holes 33 gradually approach the cooling body 27 from the bottom to the top. The cold air flow path of the convection holes 33 is the same as the cold air flow path of the cold air outlet 29, and the flow direction is opposite. Since the cold air outlet 29 sprays obliquely flowing cold air, the cold air will contact the laser thermometer 5 during the diffusion process. It should be noted that this contact means that the cold air has flowed to the laser thermometer 5 before diffusing to the base surface, that is, the detection path of the laser thermometer 5 An overlapping area is generated with the moving path of the cold air, and this overlapping area is located above the substrate, resulting in that the measurement value of the laser thermometer 5 is equivalent to the temperature of the cold air in the overlapping area, and it cannot accurately reflect the substrate temperature at the position to be welded, which seriously affects the temperature measurement accuracy. For this reason, a cold air convection plate 31 is designed to prevent the cold air from directly acting on the laser thermometer 5. Specifically, the cold air that is convected with the cold air outlet 29 is ejected through the convection hole 33, so that the cold air ejected toward the laser thermometer 5 is impacted and diffused upward and downward. The collision of the two convective cold air can accelerate the diffusion rate of the cold air, ensuring that the cooling energy can be directly and quickly diffused to the position to be welded on the substrate, and can also prevent the cold air from acting on the laser thermometer 5, thereby avoiding the influence of the cold air on the temperature measurement, and further improving the temperature measurement accuracy of the substrate.

[0036] In another embodiment, if Figure 7 As shown, the quenching mechanism includes a heat sink 100, a quenching sink 110, a pump assembly, a drive assembly, and a mounting frame. The mounting frame is rotatably assembled in the quenching sink 110, the quenching sink 110 is coaxially arranged in the heat sink 100, the pump assembly pumps the coolant in the heat sink 100 into the quenching sink 110 to quench and cool the gear 330 on the mounting frame, and the coolant in the quenching sink 110 overflows and enters the heat sink 100 for heat dissipation and cooling.

[0037] Specifically, the mounting frame includes a central shaft 300, an adjustment shaft 310 and an assembly part 330. The central shaft 300 extends vertically, the adjustment shafts 310 are evenly arranged in the circumferential direction of the central shaft 300, the axis of the adjustment shaft 310 extends radially of the central shaft 300, the middle part of the assembly part 330 is hinged to one end of the adjustment shaft 310 away from the central shaft 300, and the axis of the assembly part 330 is perpendicular to the axis of the adjustment shaft 310, so that the assembly part 330 can swing around the axis of the adjustment shaft 310. A locking structure (not shown in the figure) is provided between the assembly part and the adjustment shaft 310, and after the assembly part adjusts the tilt angle, the locking structure can lock the assembly part and the adjustment shaft 310.

[0038] Specifically, each assembly 330 can simultaneously hold a plurality of picks to be quenched. When the picks are cooled, the assembly 330 can rotate, so that the outer surface of the picks is cooled evenly, reducing the internal stress generated by the quenching and cooling of the picks, and avoiding deformation of the picks due to quenching.

[0039] The driving assembly includes a driving motor (not shown in the figure), a pulley 400 and a positioning frame 410. The positioning frame 410 is detachably fixedly mounted on the heat sink 100 and is located above the quenching pool 110. The pulley 400 and the mounting frame are both rotatably mounted on the positioning frame 410. The bottom of the quenching pool 110 is correspondingly provided with a matching groove 120. When in use, the upper and lower ends of the central axis 300 of the mounting frame are respectively rotatably matched with the positioning frame 410 and the matching groove 120. The positioning frame 410 and the matching groove 120 jointly limit the position of the central axis 300. The driving motor drives the central axis 300 to rotate through the pulley 400, so as to drive the entire mounting frame to rotate between the positioning frame 410 and the matching groove 120, thereby driving the assembly 330 to revolve around the central axis 300.

[0040] Specifically, the pump pipe 200 of the pump assembly is evenly spaced along the circumference of the quenching pool 110, and the pump pipe 200 can pump the coolant in the heat sink 100 into the quenching pool 110 to cool the pick in the assembly 330 on the mounting frame. The pump pipe 200 is specifically a metal hose that can change the liquid outlet direction. The liquid outlet direction of the pump pipe 200 is set away from the center of the quenching pool 110, so that the coolant pumped by the pump pipe 200 forms a stable vortex in the quenching pool 110.

[0041] In this embodiment, from a top view, the assembly 330 revolves clockwise around the central axis 300, and the eddy current in the quenching pool 110 flows in a counterclockwise direction, so that the revolution direction of the pick is opposite to the spiral flow direction of the eddy current, so as to accelerate the relative movement speed of the pick and the coolant. The direction in which the pick moves relative to the coolant is assumed to be a first direction, and the angle between the axis of the assembly 330 and the first direction is α, which is maintained at 60° or 120°, so that when the coolant flows over the pick surface, it can quickly and effectively carry away the bubbles generated on the pick surface, thereby preventing the bubbles from gathering on the pick surface and affecting the cooling of the pick, thereby effectively eliminating the distortion of the pick surface caused by inconsistent cooling speed, and improving the quenching quality of the gear 330.

[0042] In addition, the quenching mechanism also includes a bubble detection component and a temperature detection component. The bubble detection component is used to detect the amount of bubbles generated on the surface of the pick in real time, and the temperature control component is used to control the temperature of the coolant in the quenching pool 110.

[0043] As described above, although the present invention has been shown and described with reference to specific preferred embodiments, it should not be construed as limiting the present invention itself. Various changes may be made to it in form and detail without departing from the spirit and scope of the present invention as defined in the appended claims.
