Abstract

The present invention discloses a fully automatic bottom wafer welding device, comprising a welding table, a fully automatic welding manipulator, a plurality of clamping plates, a movable block, a screw, a first protective tube, a second protective tube, and a pressure plate. A plug-in plate is inserted between the two screws and extends into the first protective tube through the second protective tube. On the one hand, it does not affect the self-rotation and mutual approach of the two screws. On the other hand, after the bottom wafer is clamped and stabilized, during welding, the protection of the first and second protective tubes is used to prevent welding slag from splashing onto the screw, affecting the threaded connection movement between the screw and the protective tube, and making it inconvenient to clean the welding slag splashed onto the screw. The top of the connecting block and the movable block are in a prism structure, which prevents the sputtered welding slag from accumulating on the top of the connecting block and the movable block when the automatic welding manipulator is welding, affecting the rotation of the clamping plate, the connecting block and the movable block, and preventing the welding slag from entering the rotating part between the clamping plate and the connecting block, and the rotating part between the movable block and the clamping plate, which is not conducive to cleaning.

Description

Technical Field

[0001] The present invention relates to the technical field of fully automatic welding structures for cup covers, in particular to a fully automatic bottom disc welding device. Background Art

[0002] Cup lid bottom disc welding is a process that involves welding and fixing the circular part at the bottom of the cup lid to the cup body or other structures;

[0003] During fully automated welding, a fixed clamping device is used to stably hold the workpiece, ensuring accurate and stable welding operations. Many existing welding devices use screws to adjust clamping force and position to accommodate workpieces of varying sizes and shapes. However, welding slag generated during the welding process can easily enter the screw's thread gap, causing wear, sticking, and even damage, which in turn affects the clamping device's adjustment accuracy and service life.

[0004] To this end, we propose a fully automatic bottom wafer welding device. Summary of the Invention

[0005] The object of the present invention is to provide a fully automatic bottom wafer welding device to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned object, the present invention provides a fully automatic bottom wafer welding device, comprising a welding table and a fully automatic welding manipulator;

[0007] It also includes: multiple clamping plates rotatably connected to the welding table, one end of the clamping plate is rotatably connected to a movable block, a screw is threadedly connected to the movable block, two movable blocks are respectively fixedly connected to a first protective tube and a second protective tube that are sleeved with the screw, a pressure plate is movably inserted into the protective tube, and a plug-in plate is inserted between the two screws.

[0008] Furthermore, the inner wall diameter of the first protection tube is larger than the outer wall diameter of the second protection tube.

[0009] Furthermore, the first protective tube is fixedly connected to a limit frame plate that is slidably matched with the pressure plate.

[0010] Furthermore, an inclined surface is cut at the corner of the pressing plate, and the second protective tube is pressed and matched with the inclined surface.

[0011] Furthermore, a plug-in plate that is slidably engaged with the pressure plate is provided on the plug-in plate, and a tension spring is hung between the plug-in plate and the pressure plate.

[0012] Furthermore, the clamping plate has an arc-shaped structure, and the first contact plate is fixedly connected to the clamping plate.

[0013] Furthermore, the other end of the clamping plate is rotatably connected to a connecting block fixedly connected to the welding table, and the connecting block and the top of the movable block form a prism structure.

[0014] Furthermore, a transverse plate is inserted between the two clamping plates, and a second contact plate is fixedly connected to the transverse plate.

[0015] Furthermore, one of the ends of the screw rods is hingedly connected to a handle rod.

[0016] Furthermore, the plug plate is provided with a groove for plugging and cooperating with the second protective tube.

[0017] Furthermore, the other end of the plug-in board passes through another screw rod, and the plug-in board and the end of the screw rod are provided with plug-in holes, which are plugged into and matched with the two plug-in holes through a plug-in piece.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] The second protective tube is inserted deep into the first protective tube. On the one hand, this does not affect the rotation and mutual approach of the two screws. On the other hand, after the bottom disc is clamped and stabilized, the protection of the first and second protective tubes prevents welding slag from splashing onto the screw during welding, thereby affecting the threaded connection movement between the screw and the protective tube and making it difficult to clean the welding slag splashed onto the screw.

[0020] Moreover, the top of the connecting block and the movable block are in a prism structure, which prevents the spattered welding slag from accumulating on the top of the connecting block and the movable block when the automatic welding robot is welding, affecting the rotation of the clamping plate, the connecting block and the movable block, and preventing the welding slag from entering the rotating part between the clamping plate and the connecting block, and the rotating part between the movable block and the clamping plate, which is not conducive to cleaning.

[0021] The present application further enhances the fixing effect by cooperating with the second protective tube to act as the pressure plate and the horizontal plate, and adjusts the angle of the clamping plate by connecting the plug-in plate and the screw, thereby adjusting the position and angle of the first contact plate, the second contact plate, and the pressure plate to adapt to the clamping of other models of bottom wafers.

[0034] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making creative efforts are within the scope of protection of the present invention.

[0035] See also Figures 1-11 The present invention provides a fully automatic bottom wafer welding device, including a welding table 1 and a fully automatic welding manipulator 2. Before automatic welding, the bottom wafer to be welded needs to be fixed.

[0036] First, place the bottom disc between the two clamping plates 3, and rotate the handle rod 19 hinged to the end of the screw rod 5 so that the handle rod 19 and the screw rod 5 are relatively perpendicular to each other;

[0037] The handle rod 19 is rotated in a circle to make the upper screw rod 5 hinged to the handle rod 19 rotate. A plug-in plate 9 is inserted between the two screw rods 5. Through the cooperation of the plug-in plate 9, the two screw rods 5 rotate synchronously without affecting the relative sliding cooperation between the two screw rods 5.

[0038] The screw rod 5 is threadedly connected to the movable block 4, and the bottom of the movable block 4 is tightly fitted on the top surface of the welding table 1, so that the movable block 4 can only slide along the horizontal top surface of the welding table 1 and cannot change any angle. The two screw rods 5 rotate synchronously to make the movable block 4 move horizontally, and the two movable blocks 4 move towards each other.

[0039] The clamping plate 3 has an arc-shaped structure, one end of the clamping plate 3 is rotatably connected to the movable block 4, and the other end of the clamping plate 3 is rotatably connected to the connecting block 16, and the connecting block 16 is fixed on the welding table 1. When the two movable blocks 4 move towards each other, they drive the two clamping plates 3 to approach each other, thereby cooperating with the first contact plate 15 fixed on the clamping plate 3 to clamp and fix the two sides of the bottom wafer. In the process of the clamping plates 3 approaching each other, the movable plate and the screw 5 both move away from the connecting block 16.

[0040] The two movable blocks 4 are respectively fixedly connected with a first protective tube 6 and a second protective tube 7 with a sleeve screw 5. The inner wall diameter of the first protective tube 6 is larger than the outer wall diameter of the second protective tube 7. When the two movable blocks 4 approach each other, the first protective tube 6 and the second protective tube 7 are made close to each other, and the second protective tube 7 penetrates into the first protective tube 6. Through the sleeve connection and extension of the first protective tube 6 and the second protective tube 7, on the one hand, it does not affect the self-rotation and mutual approach of the two screws 5. On the other hand, after the bottom disc is clamped stably, during welding, the protection of the first protective tube 6 and the second protective tube 7 prevents welding slag from splashing onto the screw 5, affecting the threaded connection movement between the screw 5 and the protective tube, and the welding slag splashed onto the screw 5 is inconvenient to clean.

[0041] It is worth noting that the top of the connecting block 16 and the movable block 4 are in a prism structure, which prevents the spattered welding slag from accumulating on the top of the connecting block 16 and the movable block 4 during welding by the automatic welding robot, affecting the rotation of the clamping plate 3, the connecting block 16 and the movable block 4, and preventing the welding slag from entering the rotating part between the clamping plate 3 and the connecting block 16, and the rotating part between the movable block 4 and the clamping plate 3, which is not conducive to cleaning.

[0042] The first protective tube 6 is fixedly connected to a limiting frame plate 11, and a pressure plate 8 is movably inserted on the first protective tube 6. The pressure plate 8 slides in the limiting frame plate 11, and an inclined surface 12 is cut at the corner of the pressure plate 8. The second protective tube 7 is pressed and fitted with the inclined surface 12; when the second protective tube 7 is inserted into the first protective tube 6 and slides along the inner wall of the first protective tube 6, the end of the first protective tube 6 contacts and squeezes the inclined surface 12, so that the pressure plate 8 located in the limiting frame plate 11 is close to the bottom disc, thereby further fixing the bottom disc.

[0043] The plug-in plate 9 is slidably fitted with an insert plate 13 which is plugged into the pressure plate 8. A tension spring 14 is hung between the insert plate 13 and the pressure plate 8. A horizontal plate 17 is inserted between the two clamping plates 3. A second contact plate 18 is fixedly connected to the horizontal plate 17. Through the cooperation of the second contact plate 18, the pressure plate 8 and the second contact plate 18 cooperate at the same time, further strengthening the fixed clamping effect of the bottom wafer, wherein the second contact plate 18 is an elastic layer plate.

[0044] The end insertion position of the transverse plate 17 can be adjusted, so that the transverse plate 17 can be distributed obliquely.

[0045] It is worth noting that: a groove 20 is provided on the plug plate 13 for plugging into the second protective tube 7. After the second protective plate is inserted into the first protective tube 6 and acts on the inclined surface 12, the end of the second protective tube 7 is plugged and fixed in the groove 20, and the outer surface of the second protective tube 7 is pressed against the end surface of the pressure plate 8, thereby further enhancing the stabilization effect.

[0046] The end surfaces of the two movable blocks 4 that are away from each other are installed with a third protective tube 21, and the third protective tube 21 is removable;

[0047] Among them, the other end of the plug-in plate 9 passes through another screw rod 5, and plug-in holes 10 are opened at the ends of the plug-in plate 9 and the screw rod 5, and are plugged into and matched with the two plug-in holes 10 through the plug-in parts. Through the connection of the plug-in parts, the plug-in plate 9 is connected and fixed to the other screw rod 5, so that the two screw rods 5 can rotate at the same time and approach each other.

[0048] When it is necessary to adjust the angle of the clamping plate 3, even if the axial directions of the two screws 5 are tilted (the axes of the two screws 5 are not parallel to the axes of the two connecting blocks 16), to increase the applicability, the connection between the plug-in plate 9 and the other screw 5 is released by the plug-in part, and the plug-in plate 9 is moved so that the plug-in plate 9 slides on the other screw 5, and the screw 5 at the end is disengaged (the depth is controlled by pulling so that the plug-in plate 9 does not disengage from the plug-in plate 13), so that the two screws 5 are not connected, so that under the action of the grip rod 19, one screw 5 rotates and the other screw 5 does not rotate, thereby making the two clamping plates 3 asymmetrical, and adjusting the positions and angles of the first contact plate 15, the second contact plate 18, and the pressure plate 8 to adapt to the clamping of other models of bottom wafers.
