[0001] The invention relates to the technical field of welding devices, in particular to an integrated welding and polishing device for a glass water tank bracket. Background Art

[0002] As people's living standards improve, the requirements for the quality and aesthetics of bathroom products are also increasing. As an important part of bathroom facilities, the glass water tank of the toilet is gradually favored by the market due to its beautiful and modern features.

[0003] Glass water tanks are usually composed of glass panels, brackets and other functional components. Among them, the bracket plays a key role in supporting and fixing the glass panel to ensure the stability and reliability of the water tank during use. The manufacturing process of the glass water tank bracket is crucial to ensure the overall quality of the water tank.

[0004] In the production process of glass water tank brackets, welding and grinding are key processing steps. Traditionally, welding and grinding operations are often performed separately, and there is a lack of effective quality monitoring and automatic repair mechanisms. This traditional method has many disadvantages. For example, manual welding is difficult to ensure the uniformity and quality of each welding, and welding defects are prone to occur. If the subsequent grinding process is carried out under poor welding quality, not only will the surface be flattened, but welding defects may also be found during the grinding process and rework may be required, resulting in low production efficiency. Summary of the invention

[0005] The purpose of the present invention is to provide an integrated welding and grinding device for a glass water tank bracket, which solves the problem of low efficiency caused by separate welding and grinding of the glass water tank bracket in the prior art.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an integrated welding and polishing device for a glass water tank bracket, comprising a workbench, a mounting bracket is slidably connected to the workbench, a first welding bracket and a second welding bracket are vertically slidably connected to the mounting bracket, the first welding bracket and the second welding bracket are both connected with welding heads, a welding table is connected to the workbench, a bracket to be welded is placed on the welding table, the bracket to be welded has two groups of welding points, the two groups of welding heads on the first welding bracket and the second welding bracket are respectively used to weld the two groups of welding points, and when the mounting bracket moves to the upper part of the two groups of welding points, the first welding bracket and the second welding bracket are respectively moved down and weld the two groups of welding points one by one;

[0007] A grinding frame is slidably connected to the workbench, and a grinding disc for grinding welding points is rotatably connected to the grinding frame. When the welding points are uniform, the resistance fluctuation amplitude of the grinding disc moving at the welding points is low. When the welding points are missing, the resistance fluctuation amplitude of the grinding disc moving at the welding points is high. When the resistance fluctuation amplitude of the grinding disc moving at the welding points is high, the mounting frame moves in the opposite direction and welds the welding points again.

[0008] Preferably, the workbench is symmetrically rotatably connected to two screw rods, the mounting frame is symmetrically connected to two sliders, and the two sliders are respectively provided with threaded holes that cooperate with the two screw rods.

[0009] Preferably, a group of first wedge blocks corresponding to one group of welding points and a group of second wedge blocks corresponding to the other group of welding points are symmetrically arranged on both sides of the welding table, a first sliding bar is connected to the first welding frame, and a second sliding bar is connected to the second welding frame, and when the mounting frame moves, the first sliding bar and the second sliding bar slide and move downward along the inclined surfaces of the first wedge block and the second wedge block respectively, so that the first welding frame and the second welding frame move downward at the two groups of welding points respectively to enable the welding head to weld the welding points.

[0010] Preferably, a first spring is connected between the first welding frame and the mounting frame, and between the second welding frame and the mounting frame.

[0011] Preferably, the two screw rods are driven by an external motor to rotate at the same speed, and the lower part of the first wedge block and the second wedge block are provided with a first pressure-sensitive switch for controlling the reduction of the speed of the external motor, and the first slide bar and the second slide bar abut against the first pressure-sensitive switch after moving downward.

[0012] Preferably, the workbench is connected with a slide seat, a connecting rod is slidably connected to the slide seat, a round rod is connected to the side of the grinding frame, a hole matching with the round rod is opened on the connecting rod, and a second spring is connected between the round rod and the connecting rod;

[0013] A displacement sensor for detecting the round rod is arranged in the connecting rod. When the grinding disc moves to the welding point, the round rod slides toward the connecting rod. When the grinding disc moves from the non-missing weld position to the missing weld position of the welding point, the round rod slides away from the connecting rod.

[0014] Preferably, an electromagnetic driver for driving the connecting rod to slide is provided in the slide seat, and when the grinding disc moves to the welding point, the load of the electromagnetic driver increases, thereby increasing the current.

[0015] Preferably, a lifting seat is connected to the lower part of the first pressure-sensitive switch, and when the load of the electromagnetic driver increases first and then decreases, and when the round rod slides a small amount in a direction away from the connecting rod, the lifting seat moves downward.

[0017] After the grinding disc moves past the two sets of welding points, the connecting rod slides and resets toward the direction of the stand. When the electric telescopic rod is in an extended state, the resetting of the connecting rod enables the electric telescopic rod to push the rectangular piston rod to slide, thereby moving the lifting seat downward.

[0018] Preferably, a baffle is connected to a side of the stand away from the rectangular piston rod, and a third spring is connected between the baffle and the rectangular piston plate;

[0019] The baffle is provided with a second pressure-sensitive switch for controlling the reverse rotation of the screw rod, and the rectangular piston plate can abut against the second pressure-sensitive switch when sliding.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. The present invention controls the mounting frame to slide on the workbench, and the mounting frame slides over the upper parts of the two groups of welding points in sequence. The first welding frame and the second welding frame descend in sequence when passing through the two groups of welding points. When the first welding frame or the second welding frame descends, the control system controls the corresponding welding head to start and weld the two groups of welding points one by one, and moves up after the first welding frame or the second welding frame passes through the corresponding welding points. At this time, the control system controls the corresponding welding head to stop running. When the mounting frame drives the first welding frame and the second welding frame to pass through the two groups of welding points and move to the end of one end of its travel, it stops moving, and then the grinding disc moves and grinds the welding points, so that the surface of the bracket after welding is polished and flat, so as to facilitate the subsequent glass surface When the plate is installed, when the grinding disk grinds the welding point, if the welding point is uniform and there is no missing weld, the resistance fluctuation when the grinding frame moves on the upper part of the welding point is low and tends to be uniform. When the welding point is missing and the missing weld area is large, the grinding frame moves to the missing weld area of ​​the welding point, which will cause its movement resistance to suddenly decrease. That is, at this time, the resistance fluctuation when the grinding frame moves on the upper part of the welding point is large, indicating that the welding quality is poor, so the grinding frame is reset, and the mounting frame moves in the opposite direction, repeating the above welding steps, re-welding the welding point to ensure the welding quality. In this process, the mounting frame moves in the opposite direction to complete the welding, and after the mounting frame moves to the other end of its stroke, the grinding frame moves again to grind the welding point to ensure the welding quality.

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] Reference Figure 1-Figure 8 The present embodiment provides a technical solution: an integrated welding and polishing device for a glass water tank bracket, comprising a workbench 1, a mounting frame 3 is slidably connected to the workbench 1, a first welding frame 33 and a second welding frame 35 are vertically slidably connected to the mounting frame 3, a welding head 37 is connected to the first welding frame 33 and the second welding frame 35, a welding table 11 is connected to the workbench 1, a bracket 2 to be welded is placed on the welding table 11, the bracket 2 to be welded has two groups of welding points, and the two groups of welding heads 37 on the first welding frame 33 and the second welding frame 35 are respectively used to weld the two groups When the mounting frame 3 moves to the upper part of the two groups of welding points, the first welding frame 33 and the second welding frame 35 move down respectively and weld the two groups of welding points one by one; a grinding frame 42 is slidably connected to the workbench 1, and a grinding disc 43 for grinding the welding points is rotatably connected to the grinding frame 42. When the welding points are uniform, the resistance fluctuation amplitude of the grinding disc 43 moving to the welding points is low. When the welding points are missing, the resistance fluctuation amplitude of the grinding disc 43 moving to the welding points is high. When the resistance fluctuation amplitude of the grinding disc 43 moving to the welding points is high, the mounting frame 3 moves in the opposite direction and welds the welding points again.

[0033] A groove matching with the bracket 2 to be welded is provided on the welding table 11, and each part of the bracket 2 to be welded is placed in the groove on the welding table 11 respectively, at this time, the two groups of welding parts of the bracket 2 to be welded can contact each other, and the mounting frame 3 is controlled to slide on the workbench 1, and the mounting frame 3 slides over the upper part of the two groups of welding points in turn, and the first welding frame 33 and the second welding frame 35 are successively lowered when passing through the two groups of welding points. When the first welding frame 33 or the second welding frame 35 is lowered, the control system controls the corresponding welding head 37 to start and weld the two groups of welding points one by one, and the first welding frame 33 or the second welding frame 35 moves up after passing the corresponding welding points. At this time, the control system controls the corresponding welding head 37 to stop running, and when the mounting frame 3 drives the first welding frame 33 and the second welding frame 35 to pass through the two groups of welding points and move to the end of one end of its stroke, it stops moving, and then the grinding disc 43 moves and grinds the welding points, so that the surface of the bracket after welding is polished and flat, thereby facilitating the subsequent installation of the glass panel 21;

[0034] When the grinding disc 43 grinds the welding point, if the welding point is uniform and there is no missing weld, the resistance fluctuation of the grinding frame 42 when it moves on the upper part of the welding point is low and tends to be uniform. When the welding point is missing and the missing weld area is large, the grinding frame 42 moves to the missing weld area of ​​the welding point, which will cause its movement resistance to suddenly decrease. That is, at this time, the resistance fluctuation of the grinding frame 42 when it moves on the upper part of the welding point is large, indicating that the welding quality is poor, so the grinding frame 42 is reset, and the mounting frame 3 moves in the reverse direction, repeating the above welding steps, re-welding the welding point to ensure the welding quality. In this process, the mounting frame 3 moves in the reverse direction to complete the welding, and after the mounting frame 3 moves to the other end of its stroke, the grinding frame 42 moves again to grind the welding point to ensure the welding quality.

[0035] In addition, the control system monitors the remaining welding material in real time. The specific monitoring technology is the existing technology. If there is a shortage of welding materials due to insufficient welding materials, an alarm will be issued. After the welding materials are replenished, the device will repeat the above actions to perform welding and grinding.

[0036] Two screw rods 31 are symmetrically connected to the workbench 1 for rotation, and two sliders 32 are symmetrically connected to the mounting frame 3 . The two sliders 32 are respectively provided with threaded holes that match the two screw rods 31 .

[0037] The two screw rods 31 rotate synchronously and at the same speed to drive the two sliders 32 to slide synchronously, so that the mounting frame 3 moves on the workbench 1 .

[0038] A group of first wedge blocks 341 corresponding to one group of welding points and a group of second wedge blocks 361 corresponding to the other group of welding points are symmetrically arranged on both sides of the welding table 11. The first welding frame 33 is connected to the first slide bar 34, and the second welding frame 35 is connected to the second slide bar 36. When the mounting frame 3 moves, the first slide bar 34 and the second slide bar 36 slide and move downward along the inclined surfaces of the first wedge block 341 and the second wedge block 361 respectively, so that the first welding frame 33 and the second welding frame 35 move downward at the two groups of welding points respectively so that the welding head 37 welds the welding points.

[0039] As the mounting frame 3 continues to move, the first slide bar 34 and the second slide bar 36 slide along the inclined surfaces of the first wedge block 341 and the second wedge block 361 respectively. Due to the guiding effect of the inclined surfaces, the first welding frame 33 and the second welding frame 35 will move down respectively at the two groups of welding points, so that the corresponding welding heads 37 approach the welding points and start to weld the welding points.

[0040] A first spring 38 is connected between the first welding frame 33 and the mounting frame 3 , and between the second welding frame 35 and the mounting frame 3 .

[0041] The first spring 38 is provided so that the first welding frame 33 and the second welding frame 35 can be supported, so that the first slide bar 34 and the second slide bar 36 will not move downward relative to the mounting frame 3 when they have not moved to the first wedge block 341 or the second wedge block 361. At the same time, after the first slide bar 34 and the second slide bar 36 move past the first wedge block 341 or the second wedge block 361, the spring can lift the corresponding first welding frame 33 and the second welding frame 35 so that they are away from the bracket 2 to be welded, and the welding head 37 can be closed in time.

[0042] It should be noted again that the first wedge block 341 and the second wedge block 361 are both arranged in an inverted trapezoidal shape. When the first slide bar 34 or the second slide bar 36 moves to the lowest point, the welding head 37 can just be located above the welding point. At this time, the welding head 37 is started, so that the welding effect of the welding point is not affected by the movement of the welding head 37.

[0043] The two screw rods 31 are driven by an external motor to rotate at the same speed. The lower parts of the first wedge block 341 and the second wedge block 361 are provided with a first pressure-sensitive switch 39 for controlling the external motor to reduce the speed. After the first slide bar 34 and the second slide bar 36 move downward, they both abut against the first pressure-sensitive switch 39.

[0044] After the first slide bar 34 and the second slide bar 36 move downward, they will abut against the first pressure-sensitive switch 39 at the lower part of the first wedge block 341 and the second wedge block 361. The first pressure-sensitive switch 39 will control the external motor to reduce the speed, which can make the welding process more stable and avoid the welding quality degradation caused by excessive welding speed. At the same time, when the mounting frame 3 does not pass the welding point, the speed of the screw rod 31 is relatively fast, thereby ensuring that the mounting frame 3 can quickly move to the welding point and ensure the welding efficiency.

[0045] A slide seat 4 is connected to the workbench 1, and a connecting rod 41 is slidably connected to the slide seat 4. A round rod 44 is connected to the side of the grinding frame 42. A hole matching the round rod 44 is opened on the connecting rod 41, and a second spring 45 is connected between the round rod 44 and the connecting rod 41; a displacement sensor for detecting the round rod 44 is arranged in the connecting rod 41. When the grinding disc 43 moves to the welding point, the round rod 44 slides toward the connecting rod 41. When the grinding disc 43 moves from the non-missing weld position to the missing weld position of the welding point, the round rod 44 slides in the direction away from the connecting rod 41.

[0046] A displacement sensor is provided in the connecting rod 41 for detecting the displacement of the round rod 44. When the grinding disc 43 just contacts the welding point, the welding point forms resistance to the movement of the grinding disc 43. At this time, the round rod 44 slides in the direction of the connecting rod 41, providing travel space for the sliding of the round rod 44 away from the connecting rod 41 in the subsequent process. When the grinding disc 43 moves from the non-missing weld position to the missing weld position of the welding point, there is no solder at the missing weld position to block the movement of the grinding disc 43, so that the second spring 45 pushes the round rod 44 to slide in the direction away from the connecting rod 41. This displacement change is detected by the displacement sensor, thereby judging that the welding point is missing weld.

[0047] An electromagnetic driver for driving the connecting rod 41 to slide is arranged in the slide seat 4. When the grinding disc 43 moves to the welding point, the load of the electromagnetic driver increases, thereby increasing the current.

[0048] The electromagnetic driver in the slide 4 on the workbench 1 drives the connecting rod 41 to slide, and the connecting rod 41 slides on the slide 4. Since the side round rod 44 of the grinding frame 42 cooperates with the connecting rod 41 and is connected to the second spring 45, the grinding frame 42 can move with the sliding of the connecting rod 41. When the grinding disc 43 moves to the welding point, the welding point creates resistance to the movement of the connecting rod 41. At this time, the load of the electromagnetic driver increases and the current increases. When the control system detects the increase in current, it means that the grinding disc 43 has moved to the welding point to perform the grinding operation. At this time, the displacement sensor will be controlled by the control system and started, reducing interference factors during the movement process.

[0049] A lifting seat 57 is connected to the lower part of the first pressure-sensitive switch 39 . When the load of the electromagnetic driver increases first and then decreases, and the round rod 44 slides a small amount in a direction away from the connecting rod 41 , the lifting seat 57 moves downward.

[0050] When the grinding disc 43 moves to the weld missing part, the resistance of the connecting rod 41 is also reduced, so that the load of the electromagnetic driver can be reduced at this time. Combined with the detection of the displacement sensor, the detection of whether the weld point is weld missing during the grinding process is more accurate.

[0051] A stand 5 is connected to the workbench 1, and a rectangular piston rod 51 is slidably connected in the stand 5. A rectangular piston plate 52 is connected to the end of the rectangular piston rod 51. An air pipe 56 is connected between the sliding cavity in the stand 5 that cooperates with the rectangular piston plate 52 and the sliding cavity of the lifting seat 57. An electric telescopic rod 46 is connected to the end of the connecting rod 41 away from the grinding frame 42. The load of the electromagnetic drive increases first and then decreases, and when the round rod 44 slides a small amount in the direction away from the connecting rod 41, the electric telescopic rod 46 extends; after the grinding disc 43 moves past the two sets of welding points, the connecting rod 41 slides and resets in the direction of the stand 5. When the electric telescopic rod 46 is in an extended state, the reset of the connecting rod 41 can enable the electric telescopic rod 46 to push the rectangular piston rod 51 to slide, thereby moving the lifting seat 57 downward.

[0052] In the above action, the load of the electromagnetic driver increases first and then decreases, and when the round rod 44 slides a small amount in the direction away from the connecting rod 41, it indicates that there is a missing weld at the welding point at this time. After receiving the above signal, the control system will control the electric telescopic rod 46 to extend, so that after the connecting rod 41 is reset, the extended electric telescopic rod 46 can push the rectangular piston rod 51 to slide. At this time, the rectangular piston rod 51 drives the rectangular piston plate 52 to slide synchronously, and the sliding of the rectangular piston plate 52 generates negative pressure, so that the air in the sliding cavity of the lifting seat 57 is extracted through the air pipe 56, so that the lifting seat 57 drives the first pressure-sensitive switch 39 to move downward, and then the external motor drives the mounting frame 3 to move in the opposite direction to perform the repair welding operation on the welding point. At this time, the first pressure-sensitive switch 39 is in a downward state, so that the downward movement of the first slide bar 34 and the second slide bar 36 will not conflict with the first pressure-sensitive switch 39, and then the moving speed of the mounting frame 3 will not be reduced during the repair welding process, so that there will be no excessive solder at the welding point, which reduces the consumption of welding materials on the one hand and facilitates the subsequent grinding on the other hand.

[0053] When the control system controls the grinding frame 42 to move again, when the current changes of the displacement sensor and the electromagnetic driver are transmitted to the control system, the control system no longer controls the extension of the electric telescopic rod 46, because the welding point after repair welding will inevitably not be flat, thereby eliminating the influence of this factor.

[0054] A baffle 53 is connected to the side of the stand 5 away from the rectangular piston rod 51, and a third spring 54 is connected between the baffle 53 and the rectangular piston plate 52; a second pressure-sensitive switch 55 for controlling the reversal of the screw rod 31 is provided on the baffle 53, and the rectangular piston plate 52 can abut against the second pressure-sensitive switch 55 when sliding.

[0055] The control system controls the connecting rod 41 to move and shorten the electric telescopic rod 46 when grinding the welding point after the repair welding. After the second grinding, the welding point can basically meet the required quality requirements. At this time, the welded bracket is removed and the bracket 2 to be welded is placed for welding;

[0056] In addition, the extension of the electric telescopic rod 46 allows the rectangular piston plate 52 to contact the second pressure-sensitive switch 55 when it is pushed. At this time, no manual operation is required, and the second pressure-sensitive switch 55 will control the screw rod 31 to flip to perform the repair welding action. Moreover, when the movement of the connecting rod 41 after the repair welding polishes the welding point, the third spring 54 can push the rectangular piston plate 52 to reset, so that the first pressure-sensitive switch 39 is reset, so that the speed at which the mounting frame 3 moves to the welding point can still be reduced when welding the next bracket 2 to be welded.

[0057] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
