Description

Technical Field

[0001] The present invention relates to the technical field of fully automatic welding structures for cup lids, and more specifically to a fully automatic bottom disc welding device. Background Art

[0002] The welding of the bottom disc of a cup lid involves the process of welding and fixing a circular component at the bottom of the cup lid to the cup body or other structures; During the fully automatic welding process, a fixed clamping device is used to stably clamp the workpiece to ensure the accuracy and stability of the welding operation. Many existing welding devices use screws to adjust the clamping force and position to adapt to workpieces of different sizes and shapes. However, during the welding process, welding slag is likely to enter the thread gaps of the screws, resulting in wear, jamming, or even damage to the screws, thereby affecting the adjustment accuracy and service life of the clamping device.

[0003] Therefore, we propose a fully automatic bottom disc welding device. Summary of the Invention

[0004] The purpose of the present invention is to provide a fully automatic bottom disc welding device to solve the problems raised in the above background art.

[0005] To achieve the above purpose, the present invention provides a fully automatic bottom disc welding device, including a welding table and a fully automatic welding manipulator; It further includes: a plurality of clamping plates rotatably connected to the welding table, one end of each clamping plate is rotatably connected to a movable block, a screw is threadedly connected to the movable block, two of the movable blocks are respectively fixedly connected to a first protective tube and a second protective tube sleeving the screw, a pressure-resistant plate is movably inserted into the protective tube, and an insertion plate is inserted between the two screws.

[0006] Further, the inner diameter of the first protective tube is larger than the outer diameter of the second protective tube.

[0007] Further, the first protective tube is fixedly communicated with a limit frame plate slidably matched with the pressure-resistant plate.

[0008] Further, inclined surfaces are cut at the corners of the pressure-resistant plate, and the second protective tube is in pressure contact with the inclined surfaces.

[0009] Further, a plug plate slidably matched with the pressure-resistant plate is slidably arranged on the insertion plate, and a tension spring is hung between the plug plate and the pressure-resistant plate.

[0010] Further, the clamping plate has an arc-shaped structure, and a first contact plate is fixedly connected to the clamping plate.

[0011] Further, the other end of the clamping plate is rotatably connected to a connection block fixedly connected to the welding table, and the connection block and the top of the movable block have a frustum structure.

[0012] Further, a cross plate is inserted between the two clamping plates, and a second contact plate is fixedly connected to the cross plate.

[0013] Further, a grip rod is hinged to the end of one of the screw rods.

[0014] Further, a groove for inserting and mating with the second protective tube is provided on the insertion plate.

[0015] Further, the other end of the insertion plate penetrates through another screw rod, and insertion holes are provided at the end of the insertion plate and the screw rod, and the two insertion holes are inserted and mated through an insertion member.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: By inserting the second protective tube into the first protective tube, on the one hand, it does not affect the rotation and mutual approach of the two screw rods. On the other hand, after the bottom circular plate is stably clamped, during welding, through the protection of the first protective tube and the second protective tube, it is avoided that welding slag splashes onto the screw rods, affecting the threaded connection movement between the screw rods and the protective tubes, and it is inconvenient to clean the welding slag splashed onto the screw rods; Moreover, the connection block and the top of the movable block are in a frustum structure, which avoids the accumulation of sputtered welding slag on the top of the connection block and the movable block during the welding of the automatic welding manipulator, affecting the rotation of the clamping plate with the connection block and the movable block, and avoiding the welding slag from entering the rotation points between the clamping plate and the connection block and between the movable block and the clamping plate, which is not conducive to cleaning.

[0017] The present application also further strengthens the fixing effect through the cooperation of the second protective tube acting on the pressing plate and the cross plate, and also adjusts the angle of the clamping plate through the connection between the insertion plate and the screw rod, so as to adjust the positions and angles of the first contact plate, the second contact plate, and the pressing plate, so as to adapt to the clamping of bottom circular plates of other models.

Detailed implementation manners

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0021] Please refer to Figures 1-11 , the present invention provides a full-automatic bottom wafer welding device, including a welding table 1 and a full-automatic welding manipulator 2. Before automatic welding, it is necessary to fix the bottom wafer to be welded.

[0022] First, place the bottom wafer between the two clamping plates 3, and rotate the grip rod 19 hinged to the end of the screw 5 so that the grip rod 19 and the screw 5 are relatively perpendicular to each other; Rotate the grip rod 19 circumferentially, so that the upper screw 5 hinged to the grip rod 19 rotates self-driven. An insertion board 9 is inserted between the two screws 5. Through the cooperation of the insertion board 9, the two screws 5 rotate synchronously and do not affect the relative sliding fit between the two screws 5.

[0023] The screw 5 is threadedly connected to the movable block 4, and the bottom of the movable block 4 is closely attached to 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 undergo any angular transformation. The two screws 5 rotate synchronously, causing the movable block 4 to move horizontally, and the two movable blocks 4 move in a direction approaching each other.

[0024] The clamping plate 3 is in an arc 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, while the connecting block 16 is fixed on the welding table 1. When the two movable blocks 4 move closer to each other, they drive the two clamping plates 3 to move closer to each other, so as to cooperate with the first contact plate 15 fixed on the clamping plate 3 to clamp and fix both sides of the bottom circular sheet. Among them, during the process of the clamping plates 3 moving closer to each other, the movable plate and the screw rod 5 both move away from the connecting block 16.

[0025] The two movable blocks 4 are respectively fixedly connected with a first protective tube 6 and a second protective tube 7 sleeving the screw rod 5. The inner wall diameter of the first protective tube 6 is larger than the outer wall diameter of the second protective tube 7. While the two movable blocks 4 move closer to each other, the first protective tube 6 and the second protective tube 7 move closer to each other, and the second protective tube 7 extends into the first protective tube 6. Through the sleeving and telescoping of the first protective tube 6 and the second protective tube 7, on the one hand, it does not affect the rotation and mutual approach of the two screw rods 5. On the other hand, after the bottom circular sheet is stably clamped, during welding, through the protection of the first protective tube 6 and the second protective tube 7, it is avoided that welding slag splashes onto the screw rod 5, affecting the threaded connection movement between the screw rod 5 and the protective tube, and it is inconvenient to clean the welding slag splashed onto the screw rod 5.

[0026] It should be noted that: the connecting block 16 and the top of the movable block 4 are in a frustum structure, which avoids the welding slag sputtered during the automatic welding manipulator welding from accumulating on the top of the connecting block 16 and the movable block 4, affecting the rotation of the clamping plate 3 with the connecting block 16 and the movable block 4, and avoiding the welding slag from entering the rotation points between the clamping plate 3 and the connecting block 16, and between the movable block 4 and the clamping plate 3, which is not conducive to cleaning.

[0027] A limiting frame plate 11 is fixedly communicated with the first protective tube 6. A pressing plate 8 is movably inserted into the first protective tube 6, and the pressing plate 8 slides within the limiting frame plate 11. An inclined surface 12 is cut at the corner of the pressing plate 8, and the second protective tube 7 is in pressing fit with the inclined surface 12; when the second protective tube 7 is sleeved 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 presses the inclined surface 12, so that the pressing plate 8 located within the limiting frame plate 11 approaches the bottom circular sheet, thereby further fixing the bottom circular sheet.

[0028] A plug-in plate 9 is slidably fitted with a plug board 13 that is in plug-in fit with the pressing plate 8. A tension spring 14 is hung between the plug board 13 and the pressing plate 8. A cross plate 17 is inserted between the two clamping plates 3, and a second contact plate 18 is fixedly connected to the cross plate 17. Through the cooperation of the second contact plate 18, the pressing plate 8 and the second contact plate 18 cooperate simultaneously to further enhance the fixed clamping effect on the bottom circular sheet, where the second contact plate 18 is an elastic laminated plate.

[0029] Among them, the insertion position of the end of the cross plate 17 can be adjusted, and the cross plate 17 can be distributed obliquely.

[0030] It should be noted that: a groove 20 for plugging and cooperating with the second protection tube 7 is formed on the plug board 13. After the second protection plate is inserted into the first protection tube 6 and acts on the inclined surface 12, the end of the second protection tube 7 is plugged and fixed in the groove 20, and the outer surface of the second protection tube 7 is in pressing cooperation with the end surface of the pressing plate 8, thereby further enhancing the stability effect.

[0031] Third protection tubes 21 are installed on the end faces of the two movable blocks 4 away from each other, and the third protection tubes 21 can be disassembled and assembled; Wherein, the other end of the plugging board 9 penetrates through another screw 5. Plugging holes 10 are formed at the end parts of the plugging board 9 and the screw 5, and are plugged and cooperated with the two plugging holes 10 through a plugging member. Through the connection of the plugging member, the plugging board 9 is connected and fixed with another screw 5, so as to facilitate the simultaneous rotation of the two screws 5 and their approaching each other.

[0032] When the angle of the clamping plate 3 needs to be adjusted, even if the axial directions of the two screws 5 are inclined (the axes of the two screws 5 are not parallel to the axes of the two connecting blocks 16), when increasing the applicability, by releasing the connection relationship between the plugging member and the plugging board 9 and another screw 5, and then moving the plugging board 9, the plugging board 9 slides on another screw 5 and disengages from the screw 5 at the end part (by pulling to control the depth, so that the plugging board 9 does not disengage from the plug board 13), so that the two screws 5 are not connected. Thus, under the action of the grip rod 19, one screw 5 rotates and the other screw 5 does not rotate, so that the two clamping plates 3 are asymmetric, and the positions and angles of the first contact plate 15, the second contact plate 18, and the pressing plate 8 are adjusted, so as to adapt to the clamping of bottom round pieces of other models.
