Description

Technical Field

[0001] The invention relates to an intelligent integrated radium welding device, in particular to an intelligent integrated radium welding device applied in the welding field. Background Art

[0002] ‌Radium welding‌, also known as laser welding, is a high-precision welding technology that uses the energy of a high-power laser beam to partially melt metal materials and achieve the purpose of welding through natural solidification of the molten pool. This technology is increasingly used in the manufacturing industry due to its advantages such as easy operation, low cost, and no need for additional materials. Radius welding equipment is widely used in mobile phone production. Most of the existing radium welding equipment is automated. Although it can achieve automated production, the smoke generated by welding cannot be handled well.

[0003] In order to solve the problem of welding smoke, a certain radium welding equipment on the market adopts the design of adding a smoke purifier, which has a certain market share.

[0004] The specification of Chinese patent CN201210145652.5 discloses a welding device with a fume purification function. The welding device with a fume purification function provided by the patent enables the existing space for placing the welding device to accommodate the fume purifier and the welding device at the same time, thereby reducing the space occupied. At the same time, the welding device with a fume purification function purifies more thoroughly than the existing fume purifier, and has low noise, and does not affect the working environment of the operator.

[0005] The specification of Chinese patent CN201710726211.7 discloses a smoke purification device, which effectively solves the problem that the existing smoke purification device must be shut down to replace the filter, affecting the progress of the production line and even affecting the welding performance of the product. The device comprises an air inlet pipe, a transverse sleeve is fixed at the lower end of the air inlet pipe, an air outlet pipe is fixed at the lower end of the transverse sleeve, a cylinder is slidably connected in the transverse sleeve, the cylinder and the transverse sleeve are sealed, a left through hole and a right through hole which are perpendicular to each other and do not intersect are provided in the cylinder, a cylinder is rotatably connected to the right side of the cylinder, forming a structure in which the cylinder pushes the cylinder to slide in the transverse sleeve, a curved groove is provided on the right side surface of the cylinder, a connecting rod is fixed on the air outlet pipe, which is located below the transverse sleeve and inserted into the curved groove, forming a structure in which the cylinder rotates when sliding in the transverse sleeve, thereby realizing mutual switching between the left through hole and the right through hole.

[0006] Although the existing smoke purifier can replace the filter without stopping the machine, the filter can only intercept the particles in the smoke and cannot play a good role in purifying toxic gases. In addition, the existing smoke purification device has a complex structure and is not convenient for maintenance. Summary of the invention

[0007] In view of the above-mentioned prior art, the technical problem to be solved by the present invention is to purify the smoke generated by laser welding.

[0008] In order to solve the above problems, the present invention provides an intelligent integrated radium welding equipment, including a base, and a protective box is connected to the base, and the upper side wall of the base is installed with a carrier re-throwing assembly line and a carrier unloading assembly line arranged in parallel, and the upper side wall of the base close to the carrier re-throwing assembly line is installed with a material picking robot arm, an upper carrier robot arm, a front material picking robot arm 1, a front material placing robot arm, a front material picking robot arm 2, a side robot arm 1, a side assembly robot arm, a side robot arm 2, a carrier flip module, a solder joint detection module, a material unloading robot arm, a handling robot arm, etc. A mechanical arm and a six-axis unloading mechanical arm, and a symmetrically distributed hanger plate handling module 1 and a hanger plate handling module 2 are installed at one end of the base close to the six-axis unloading mechanical arm, a front welding module is installed at the position of the base directly opposite to the front material-taking mechanical arm 2, and the front welding module is located between the carrier re-investment assembly line and the carrier offline assembly line, a side welding module is installed at the position of the base directly opposite to the side assembly mechanical arm, and the side welding module is located between the carrier re-investment assembly line and the carrier offline assembly line, and a welding defective product pendulum is installed on the upper side wall of the base directly opposite to the handling mechanical arm; A smoke purification box is installed on the side wall of the protection box located above the front welding module and the side welding module, and a smoking pipe is connected between the side wall of the smoke purification box and the interior of the protection box, a purification chamber is opened inside the smoke purification box, the upper side wall of the smoke purification box is connected with an exhaust pipe, and a negative pressure exhaust fan is installed on the upper inner wall of the purification chamber located below the exhaust pipe, and a horizontally placed integrated variable-diameter purifier is connected to the interior of the smoke purification box, the integrated variable-diameter purifier includes a threaded mounting cylinder threadedly connected to the side wall of the smoke purification box, and a sealing disk 1 is rotatably connected to the side wall of the threaded mounting cylinder, a sealing disk 2 is provided at one end of the sealing disk 1, and a gas purification cylinder is fixedly connected between the sealing disk 1 and the sealing disk 2, and a smoke purification cylinder is also connected between the sealing disk 1 and the sealing disk 2. The smoke purification cylinder is located inside the gas purification cylinder, and the side walls at both ends of the smoke purification cylinder are fixedly connected with a plurality of T-shaped sliders distributed around at equal intervals, and the side walls of the sealing disk 1 and the sealing disk 2 are provided with T-shaped sliding grooves matching the T-shaped sliders, the inner wall of the purification chamber is sealingly rotatably connected with a connecting pipe connected with the smoking pipe, and the connecting pipe runs through the interior of the smoke purification cylinder, the outer wall of the sealing disk 2 is fixedly connected with a connecting sleeve, and the connecting sleeve is sleeved on the connecting pipe, the inner wall of the connecting sleeve is fixedly inlaid with an elastic sealing ring, and the side wall of the connecting pipe is provided with a sealing groove matching the elastic sealing ring, a driving motor is installed on the inner wall of the lower end of the purification chamber, and the output end of the driving motor is connected with a reducing driving disk, and the reducing driving disk is abutted against the side of the sealing disk 1.

[0009] In the above-mentioned intelligent integrated radium welding equipment, the metal oxides, particles and toxic gases in the smoke are filtered by the rotation of the integrated variable diameter purifier. The design of the integrated purification structure is also convenient for maintenance, and can also perform self-cleaning by changing speed.

[0010] As a further improvement of the present application, the variable diameter drive disk comprises a base disk, the side wall of the base disk is provided with a plurality of equally spaced and surrounding expansion grooves, and the inner wall of each expansion groove is slidably connected with a centrifugal outer top block, a spring wire is fixedly connected between the centrifugal outer top block and the inner wall of the expansion groove, and the outer parts of the plurality of centrifugal outer top blocks are simultaneously covered with friction pads, and the friction pads are frictionally connected with the side of the sealing disk 1, and the variable diameter drive disk relies on the centrifugal force when the driving motor drives the rotation to expand the diameter, and then abuts against the side of the sealing disk 1, and the variable diameter drive disk The moving plate drives the sealing plate to rotate by means of friction, which makes it convenient to disassemble and install the integrated variable diameter purifier to prevent the variable diameter driving plate from blocking the movement of the integrated variable diameter purifier. Before the variable diameter driving plate rotates, the centrifugal outer top block is in the telescopic groove. At this time, the diameter of the variable diameter driving plate is the smallest. When the variable diameter driving plate rotates, the centrifugal outer top block is thrown out under the action of centrifugal force, and then the friction pad is pushed outward. At this time, the friction pad contacts the outer side wall of the sealing plate, and the friction pad drives the sealing plate to rotate by means of friction.

[0011] As a further improvement of the present application, a plurality of symmetrically distributed harmful gas detectors are also installed on the inner wall of the upper end of the purification chamber near the negative pressure exhaust fan. The smoke purification box also includes a gas concentration monitoring module, an early warning module and a centrifugal speed adjustment module electrically connected to the harmful gas detector, and the centrifugal speed adjustment module is electrically connected to the drive motor through the control processor. Under normal purification working conditions, the drive motor drives the integrated variable diameter purifier to rotate at a constant speed. As time goes by, the purification effect of the integrated variable diameter purifier will gradually decrease. In order to monitor the purification effect of the integrated variable diameter purifier, a harmful gas detector is used to monitor the concentration of the purified gas in real time. Once the concentration of the toxic gas is detected to exceed the set threshold, the centrifugal speed adjustment module is immediately triggered. The centrifugal speed adjustment module then controls the high and low speed changes of the drive motor, thereby driving the integrated variable diameter purifier to rotate at a variable speed. In this way, self-cleaning inside the integrated variable diameter purifier can be achieved, effectively improving the purification effect.

[0012] As a further improvement of the present application, the smoke purification tube includes a plurality of main purification sections that are equally spaced and distributed in a surrounding manner, and a T-shaped slider is installed on the main purification section, an auxiliary purification section is connected between two adjacent main purification sections, and an elastic connecting section is fixedly connected between the two ends of each auxiliary purification section and the adjacent main purification section. When the integrated variable diameter purifier is in a constant speed rotating working state, the centrifugal force has not overcome the elastic force of the elastic connecting section. At this time, the auxiliary purification section is in an inwardly contracted state, and when the integrated variable diameter purifier starts to rotate at high and low speeds, the centrifugal force on the main purification section increases in the high speed state, and the centrifugal force overcomes the elastic force of the elastic connecting section to allow the main purification section to expand outward. At this time, the auxiliary purification section is in an outwardly extended state, thereby effectively increasing the purification area, and the smoke purification tube can repeatedly shrink and expand during the high and low speed rotation process, so as to achieve a self-cleaning effect, effectively preventing particulate matter from accumulating in large quantities in the smoke purification tube and causing blockage.

[0013] As a further improvement supplement to the present application, the weight of the main purification section is greater than that of the auxiliary purification section, and the flexibility of the main purification section is less than that of the auxiliary purification section. The main purification section expands outward under the action of centrifugal force, so that the auxiliary purification section is exposed, which plays a driving role. Therefore, the weight of the main purification section must be greater than the weight of the auxiliary purification section, and the auxiliary purification section must be able to smoothly retract and expand. The main purification section must maintain its ability to shape, so the flexibility of the auxiliary purification section must be greater.

[0014] As another improvement of the present application, the gas purification cylinder includes an inner resin adsorption layer and an outer resin adsorption layer, and an activated carbon adsorption layer is filled between the inner resin adsorption layer and the outer resin adsorption layer. The inner and outer resin adsorption layers arranged inside and outside adsorb toxic gas components and play an effective purification role. The activated carbon adsorption layer can not only adsorb toxic gas components but also intercept unfiltered particulate matter, thereby further effectively improving the purification effect.

[0015] As another improvement of the present application, a semiconductor refrigerator is installed inside the exhaust pipe, and a metal filter is magnetically attracted at the upper opening of the exhaust pipe. The semiconductor refrigerator cools the exhausted gas, effectively reducing the ambient temperature inside the equipment and preventing the equipment from being affected by high temperature, while the metal filter can further filter and purify the gas.

[0016] In summary, a smoke purification box is set up in the welding area to timely discharge welding smoke and heat generated by welding, and an integrated variable diameter purifier is set up inside the smoke purification box. The centrifuge of the integrated variable diameter purifier is used to quickly adsorb metal oxides and particles in the smoke, thereby effectively improving the purification efficiency. The integrated variable diameter purifier combines solid filtration and gas filtration together, effectively simplifying the equipment structure, and the integrated variable diameter purifier can adaptively rotate at a variable speed according to the concentration of the filtered gas. The change in centrifugal force during the variable speed rotation causes the diameter of the smoke purification cylinder to change, which can not only effectively improve the purification effect, but also achieve self-cleaning.

A side welding module 21 is installed at the position of the base 1 facing the side assembly robot arm 9, and the side welding module 21 is located between the carrier re-throwing assembly line 18 and the carrier offline assembly line 19. A welding defective product pendulum plate 22 is installed on the upper side wall of the base 1 facing the handling robot arm 14; Figure 2 , 3 , 4 and Fig. 9 As shown, smoke purification boxes 23 are installed on the side walls of the protection box 2 located above the front welding module 20 and the side welding module 21, and a smoking pipe 24 is connected between the side wall of the smoke purification box 23 and the interior of the protection box 2. A purification chamber 2301 is opened inside the smoke purification box 23, and an exhaust pipe 25 is connected to the upper side wall of the smoke purification box 23. A semiconductor refrigerator is also installed inside the exhaust pipe 25, and a metal filter is magnetically attracted at the upper opening of the exhaust pipe 25. The semiconductor refrigerator cools the exhausted gas, effectively reducing the ambient temperature inside the equipment and preventing the equipment from being affected by high temperature, and the metal filter can further filter and purify the gas, and a negative pressure exhaust fan 38 (the specific model is selected according to actual needs and is not described in detail here) is installed on the upper inner wall of the purification chamber 2301 below the exhaust pipe 25. The interior of the smoke purification box 23 is connected with a horizontal An integrated variable diameter purifier 26 is arranged, the integrated variable diameter purifier 26 comprises a threaded mounting barrel 27 threadedly connected to the side wall of the smoke purification box 23, and the side wall of the threaded mounting barrel 27 is rotatably connected with a sealing disk 1 28, one end of the sealing disk 1 28 is provided with a sealing disk 29, and a gas purification barrel 30 is fixedly connected between the sealing disk 1 28 and the sealing disk 2 29, the gas purification barrel 30 comprises an inner resin adsorption layer 3001 and an outer resin adsorption layer 3002, and an activated carbon adsorption layer 3003 is filled between the inner resin adsorption layer 3001 and the outer resin adsorption layer 3002, the inner and outer resin adsorption layers 3001 and the outer resin adsorption layers 3002 arranged inside and outside adsorb toxic gas components, and play an effective purification role, and the activated carbon adsorption layer 3003 can absorb the toxic gas components while also intercepting the particulate matter that has not been filtered clean, thereby further effectively improving the purification effect; Figure 5 , 6 and Figure 7 As shown, a smoke purification tube 31 is also connected between the sealing disk 1 28 and the sealing disk 29, and the smoke purification tube 31 is located inside the gas purification tube 30, and the side walls at both ends of the smoke purification tube 31 are fixedly connected with a plurality of T-shaped sliders 32 that are equally spaced and distributed around, and the side walls of the sealing disk 1 28 and the sealing disk 29 are both provided with T-shaped slide grooves 2901 that match the T-shaped sliders 32, and the inner wall of the purification chamber 2301 is sealed and rotatably connected with a connecting tube 33 that is connected to the smoking pipe 24, and the connecting tube 33 runs through the interior of the smoke purification tube 31, the outer side wall of the sealing disk 29 is fixedly connected with a connecting sleeve 34, and the connecting sleeve 34 is sleeved on the connecting tube 33, the inner wall of the connecting sleeve 34 is fixedly inlaid with an elastic sealing ring 35, and the side wall of the connecting tube 33 is provided with a sealing groove that matches the elastic sealing ring 35; Figure 4 , 8As shown, a driving motor 36 is installed on the inner wall of the lower end of the purification chamber 2301 (the specific model is selected according to actual needs and will not be described in detail here), and the output end of the driving motor 36 is connected to a variable diameter driving disk 37, the variable diameter driving disk 37 includes a base plate 3701, and the side wall of the base plate 3701 is provided with a plurality of equally spaced and surrounding telescopic grooves 3702, and the inner wall of each telescopic groove 3702 is slidably connected with a centrifugal outer top block 3703, and a spring wire drawing 3704 is fixedly connected between the centrifugal outer top block 3703 and the inner wall of the telescopic groove 3702, and the outer parts of the plurality of centrifugal outer top blocks 3703 are simultaneously covered with friction pads 3705 (rubber material is preferably used, and other materials can also be selected according to actual needs), and the friction pads 3705 are frictionally connected to the side of the sealing disk 28, and the variable diameter driving disk 37 relies on the driving motor 3 6 drives the centrifugal force during rotation to expand the diameter, and then abuts against the side of the sealing disk 28. The variable diameter driving disk 37 relies on the friction force to drive the sealing disk 28 to rotate, which makes it convenient to disassemble and install the integrated variable diameter purifier 26 to prevent the variable diameter driving disk 37 from blocking the movement of the integrated variable diameter purifier 26. Before the variable diameter driving disk 37 rotates, the centrifugal outer top block 3703 is in the telescopic groove 3702. At this time, the diameter of the variable diameter driving disk 37 is the smallest. When the variable diameter driving disk 37 rotates, the centrifugal outer top block 3703 is thrown out under the action of centrifugal force, and then the friction pad 3705 is stretched outward. At this time, the friction pad 3705 contacts the outer side wall of the sealing disk 28. The friction pad 3705 relies on the friction force to drive the sealing disk 28 to rotate, and the variable diameter driving disk 37 abuts against the side of the sealing disk 28.

[0021] The second implementation method: Figure 4As shown, the purification chamber 2301 is also equipped with a plurality of symmetrically distributed harmful gas detectors 39 (the specific model is selected according to actual needs and will not be described in detail here) on the inner wall of the upper end near the negative pressure exhaust fan 38. The smoke purification box 23 also includes a gas concentration monitoring module, an early warning module and a centrifugal speed adjustment module electrically connected to the harmful gas detector 39. The early warning module is used to send out an alarm to the outside so that the staff can replace and clean the integrated variable diameter purifier 26 in time in advance, and the centrifugal speed adjustment module is electrically connected to the drive motor 36 through the control processor (the specific control structure and working principle of this part are well-known technologies for technicians in the relevant field and will not be described in detail here). Under normal purification working conditions, the driving motor 36 drives the integrated variable diameter purifier 26 to rotate at a constant speed. As time goes by, the purification effect of the integrated variable diameter purifier 26 will gradually decrease. In order to monitor the purification effect of the integrated variable diameter purifier 26, a harmful gas detector 39 is used to monitor the concentration of the purified gas in real time. Once the concentration of the toxic gas is detected to exceed the set threshold, the centrifugal speed adjustment module is immediately triggered. The centrifugal speed adjustment module controls the high and low speed speed change of the driving motor 36 to drive the integrated variable diameter purifier 26 to rotate at a variable speed. In this way, the internal self-cleaning of the integrated variable diameter purifier 26 can be achieved, and the purification effect can be effectively improved. Fig.10 , 11As shown, the smoke purification tube 31 includes a plurality of main purification sections 3101 (preferably fiber filter materials are used, and other filter materials can also be selected according to actual needs) that are equally spaced and distributed in a surrounding manner, and a T-shaped slider 32 is installed on the main purification section 3101, and an auxiliary purification section 3102 (preferably fiber filter materials are used, and other filter materials can also be selected according to actual needs) is connected between two adjacent main purification sections 3101. The weight of the main purification section 3101 is greater than the weight of the auxiliary purification section 3102, and the flexibility of the main purification section 3101 is less than the flexibility of the auxiliary purification section 3102. The main purification section 3101 expands outward under the action of centrifugal force, so that the auxiliary purification section 3102 is exposed, which plays a driving role. Therefore, the weight of the main purification section 3101 is greater than the weight of the auxiliary purification section 3102, and the auxiliary purification section 3102 must be able to smoothly retract and expand. The main purification section 3101 must maintain its shaping ability, so the flexibility of the auxiliary purification section 3102 must be greater. The two ends of each auxiliary purification section 3102 are fixedly connected to the adjacent main purification section 3101 with an elastic connecting section 3103 (preferably made of polyurethane elastic material, and other materials can also be selected according to actual needs). When the integrated variable diameter purifier 26 rotates at a constant speed, the centrifugal force has not overcome the elastic force of the elastic connecting section 3103. At this time, the auxiliary purification section 3102 is in an inwardly contracted state. When the integrated variable diameter purifier 26 starts to rotate at high and low speeds, the centrifugal force on the main purification section 3101 increases in the high-speed state. The centrifugal force overcomes the elastic force of the elastic connecting section 3103 and allows the main purification section 3101 to expand outward. At this time, the auxiliary purification section 3102 is in an outwardly extended state, thereby effectively increasing the purification area. In addition, the smoke purification tube 31 can repeatedly shrink and expand during the process of high and low speed rotation, so as to achieve a self-cleaning effect and effectively prevent particulate matter from accumulating in large quantities in the smoke purification tube 31 and causing blockage.

[0022] The working principle of this scheme is as follows: in the front welding and side welding working areas, the negative pressure exhaust fan 38 discharges the gas in the smoke purification box 23 to the outside, and the smoke in the welding area enters the smoke purification tube 31 through the smoke pipe 24 and the connecting pipe 33 under the action of negative pressure, and the driving motor 36 drives the variable diameter driving disk 37 to rotate. The diameter of the variable diameter driving disk 37 increases under the action of centrifugal force and is tightly attached to the side of the sealing disk 28. The variable diameter driving disk 37 drives the sealing disk 28 to rotate by friction, and the sealing disk 28 then drives the gas purification tube 30 and the smoke purification tube 31 to rotate. Under the action of centrifugal force, the metal oxides and particles in the smoke inside the smoke purification tube 31 settle on the main purification section 3101, and the toxic gas passes through the main purification section 3101 and enters the space between the smoke purification tube 31 and the gas purification tube 30. The toxic gas components are adsorbed by the gas purification tube 30 under the action of centrifugal force and negative pressure, and the purified gas is discharged from the exhaust pipe 25. The harmful gas detector 39 detects the purified gas. When the concentration of the toxic gas component exceeds the set threshold, the centrifugal speed adjustment module is triggered by the gas concentration monitoring module, and the centrifugal speed adjustment module controls the drive motor 36 to perform high and low speed speed change, thereby driving the integrated variable diameter purifier 26 to switch back and forth between high speed and low speed. In the high speed state, the centrifugal force on the main purification section 3101 increases, and the centrifugal force overcomes the elastic force of the elastic connection section 3103 to allow the main purification section 3101 to expand outward. At this time, the auxiliary purification section 3102 is in an outward state, thereby effectively increasing the purification area. In the low speed state, the elastic connection section 3103 can overcome the centrifugal force to reset the main purification section 3101, and the auxiliary purification section 3102 is retracted inward again. In this way, the smoke purification tube 31 realizes repeated diameter change during the high and low speed rotation. In the process of diameter change, not only can the purification effect be effectively improved, but also the particles gathered on the main purification section 3101 and the auxiliary purification section 3102 can be shaken off, thereby achieving a self-cleaning effect. When the harmful gas detector 39 detects that the toxic gas component is always at a high concentration, it immediately triggers the early warning module to alarm. The staff disassembles the integrated variable diameter purifier 26 by rotating the sealing disk 28 for cleaning. During cleaning, high-pressure gas is filled into the interior through the connecting sleeve 34 for flushing. The flushed particles are poured out through the connecting sleeve 34, and finally the integrated variable diameter purifier 26 is screwed back onto the smoke purification box 23.

[0023] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.
