Description

Technical Field

[0001] This invention relates to the field of automatic metal welding equipment, and more particularly to automatic welding equipment for pot ears. Background Technology

[0002] Cookware, an indispensable cooking tool in the kitchen, typically consists of two key parts: the pot body and the handles. The handles play a crucial role in facilitating the handling and movement of the pot, and must be securely fixed to both sides of the pot body through welding. However, in traditional production processes, because the welding contact surfaces between the pot body and the handles are essentially curved, the welding of the handles is primarily done manually, a method with many obvious limitations.

[0003] On the one hand, the efficiency of manual welding is greatly limited by the skill level of the operators. Different workers have varying skill levels, and even experienced masters inevitably experience fatigue after long hours of work, leading to a decrease in welding speed and making it difficult to meet the high-efficiency requirements of modern mass production. On the other hand, during the welding process, workers are prone to inconsistent welding parameters and inaccurate heat input control, such as deviations in welding time. These issues result in unstable weld appearance and quality, potentially leading to defects such as porosity and cracks. This not only affects the aesthetics of the cookware but also reduces its lifespan and safety, negatively impacting both manufacturers and consumers. Summary of the Invention

[0015] This invention has the following advantages: The invention employs a structural design that uses a fixed-point conveying system for the pot body and pot ears, enabling precise positioning of the pot body and pot ears. After positioning, four-point welding is performed simultaneously, resulting in high-quality and high-efficiency welding. The invention uses a control mechanism to closely link the rhythm of the transfer table conveying the pot body with the rhythm of the pusher plate conveying the pot ears, ensuring precise synchronization between pot body positioning and pot ear pushing. This demonstrates the precise timing control of this invention, thereby improving welding process efficiency.

[0016] This invention utilizes a first feeding mechanism and a transmission assembly to work together, completing a full cycle of "pushing-replenishing" the pot ears through the single reciprocating motion of the pusher plate. It also employs a second feeding mechanism for automatic replenishment, relying on the single reciprocating motion of the transfer table to complete a full cycle of "pushing-replenishing" the pot body. In other words, this invention achieves precise timing control of the pushing and feeding actions, effectively solving problems such as inaccurate positioning, asynchronous rhythm, and excessive manual intervention in traditional feeding methods. This improves work efficiency and ensures the continuity of the processing. The entire structure of this invention is reliable, easy to maintain, and reduces energy consumption.

[0017] This invention employs a ratchet and pawl directional transmission method, combined with the reciprocating motion of the transfer table, to achieve automatic unloading of the pot body, further improving the process flow of the processing line of this invention, realizing more comprehensive automation of the operation of this invention, improving processing efficiency, enhancing operational convenience, and further improving the continuity of the processing process.

[0018] This invention uses an adjustment mechanism to adjust the feeding rhythm of the pot body and pot ears, achieving more precise feeding operation based on the structural characteristics of the pot body, thereby improving the welding quality of the pot ears and enhancing the overall production quality of the cookware.

Detailed Implementation

[0033] References to embodiments herein mean that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of the invention. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0034] Example: Automatic welding equipment for pot ears, see reference. Figures 1-2 The system includes: a mounting frame 101; mounting portions 105 slidably mounted on the left and right sides of the mounting frame 101; a transfer platform 1 mounted on the mounting portions 105 for transferring the pot body 002; a pad 103 fixedly mounted on the transfer platform 1, which supports the pot body 002 inside the pot body 002 to improve the stability of the transfer platform 1 in transferring the pot body 002; two side frames 102 fixedly mounted on the front of the mounting frame 101; and four welding torches 104 fixedly mounted on the side frames 102, two on each of the two side frames 102, for welding the two pot ears 001 respectively. Welding is performed at two welding points on each side; feeding racks 2 are fixedly installed on the two side frames 102 respectively, which are used to place the pot ears 001; pusher plates 3 are slidably installed on the two side frames 102. The displacement of the pusher plates 3 will pass through the feeding racks 2 and push the pot ears 001 to accurately push the pot ears 001 to both sides of the pot body 002. The contact side of the pusher plates 3 with the pot ears 001 is provided with grooves that are adapted to the pot ears 001 to limit the position of the pot ears 001 during the pushing process, so that the pusher plates 3 can push the pot ears 001 stably and prevent the pot ears 001 from shifting position during the process.

[0035] The transfer table 1 moves the pot body 002 to the front of the mounting frame 101, and the pusher plate 3 precisely positions the two pot ears 001 to both sides of the pot body 002. Then the welding gun 104 performs four-point welding simultaneously to achieve high-quality and high-efficiency welding processing.

[0036] See Figure 2 The equipment also includes: a drive assembly mounted on the mounting frame 101 for driving the displacement of the transfer table 1, comprising: screws 106 rotatably mounted on the left and right sides of the mounting frame 101, the screws 106 being threadedly engaged with the mounting part 105, and their forward and reverse rotation realizing the forward and backward reciprocating displacement of the mounting part 105; a synchronous belt assembly 107 disposed between the two screws 106; and a servo motor 108 fixedly mounted on the rear right side of the mounting frame 101, the output end of the servo motor 108 being fixed to the rear end of the right screw 106, providing driving force for the rotation of the screw 106. By starting the servo motor 108 to rhythmically drive the screws 106 to rotate forward and reverse, stable forward and backward displacement control of the transfer table 1 can be achieved.

[0037] See Figure 3The equipment also includes: a first conveying mechanism for automatically adding pot ears 001, which is set in each feeding rack 2, comprising: a first mounting shaft 201 rotatably mounted on both sides of the feeding rack 2; a conveyor belt 202 that is wound around the first mounting shaft 201 via a transmission wheel and is vertically displaced as the first mounting shaft 201 rotates; and a conveyor plate 203 fixedly mounted on the conveyor belt 202, with the conveyor plates 203 on both sides cooperating to support and transport the pot ears 001.

[0038] See Figure 4 The equipment also includes a transmission assembly disposed between the first conveying mechanism and the pusher plate 3. This assembly coordinates the conveying rhythm of the first conveying mechanism and the pushing rhythm of the pusher plate 3, ensuring synchronized operation. Through linkage control, it optimizes the power source configuration, thereby reducing overall energy consumption. A transmission assembly is provided between the first conveying mechanism and the pusher plate 3 on each of the two side frames 102. The transmission assembly includes two second mounting shafts 204 rotatably mounted on the side frames 102, symmetrically arranged on both sides of the pusher plate 3. 1. Perpendicular to the second mounting shaft 204; a bevel gear set 205 fixedly installed between the first mounting shaft 201 and the second mounting shaft 204, forming a 90-degree power steering transmission pair; racks 206 fixedly installed on both sides of the pusher plate 3; a one-way gear 207 fixedly installed on the second mounting shaft 204, the one-way gear 207 and the rack 206 on the corresponding side form a meshing transmission, the one-way gear 207 adopts a one-way clutch structure, so that the one-way gear 207 has a single transmission capability, and only allows the pusher plate 3 to drive the first mounting shaft 201 to rotate when it retracts.

[0039] When the pusher plate 3 pushes the pot ears 001 outward, the one-way gear 207 idles and does not transmit power to the second mounting shaft 204. At this time, the first conveying mechanism remains stationary, and all pot ears 001 in the unloading rack 2 maintain their original positions. When the pusher plate 3 finishes pushing and begins to retract, the rack 206 meshes with the one-way gear 207, causing the second mounting shaft 204 to rotate. This rotation is transmitted to the first mounting shaft 201 through the bevel gear set 205, controlling the downward displacement of the conveyor belt 202. The conveyor plate 203 then supports the pot ears. 001 is conveyed downwards, and the engagement length of the rack 206 with the one-way gear 207 will cause all the pot ears 001 to move by the distance of the arrangement height of a single layer of pot ears 001. Therefore, the bottom conveyor plate 203 will detach from the pot ears 001 it supports, and the pot ears 001 will automatically fall into the pushing area of ​​the pusher plate 3. At the same time, the top conveyor plate 203 will turn in to receive the pot ears 001 to be arranged above. Finally, automatic feeding is achieved in the automatic pushing rhythm of the pot ears 001.

[0040] See Figure 5The equipment also includes: a control mechanism disposed between the transfer platform 1 and the pusher plate 3, which realizes the transmission control of the displacement of the transfer platform 1 to the displacement of the pusher plate 3, that is, coordinates the conveying rhythm of the pot body 002 and the conveying rhythm of the pot ears 001, and optimizes the energy structure to save energy consumption. The transfer platform 1 and the pusher plates 3 on both sides are provided with a set of control mechanisms. The control mechanism includes: guide rails 301 are provided on the mounting part 105 and the side frame 102 respectively; hinge seats 302 are slidably installed on the two guide rails 301 respectively; a first return spring 303 is fixedly installed between the side frame 102 and the hinge seats 302 on it; and a telescopic arm 304 is rotatably installed between the two hinge seats 302. The telescopic arm 304 consists of blocks connected to the two hinge seats 302 respectively and connecting the two hinge seats 302. The rod is composed of two blocks and slides with each other. A first adjusting spring 305 is fixedly installed on the telescopic arm 304, which makes the length of the telescopic arm 304 adapt to change. A control plate 306 is slidably installed on the side frame 102 and is connected to the pusher plate 3 to control the displacement of the pusher plate 3. Two first toothed plates 307 are slidably installed in the side frame 102, with the teeth of the two first toothed plates 307 facing opposite directions. One is fixed to the control plate 306 and the other is fixed to the hinge seat 302 on the side frame 102. A first gear 308 is rotatably installed in the side frame 102 using a support. The two first toothed plates 307 mesh with the first gear 308 from both sides to achieve synchronous reverse transmission.

[0041] See Figure 5 Taking the right-side control mechanism and the right-side pusher plate 3 as an example, its working process is as follows: When the transfer table 1 moves forward, firstly, under the force of the first adjusting spring 305 extending the telescopic arm 304, the hinge seat 302 on the mounting part 105 will first move along the guide rail 301 to its rear. As the transfer table 1 continues to move forward, the two hinge seats 302 will cause the telescopic arm 304 to rotate. Under the action of the first adjusting spring 305, the telescopic arm 304 adaptively extends and retracts, automatically compensating for the length difference caused by the angle change. At this time, the hinge seat 302 on the side frame 102 moves to the right, stretching the first reset spring 303, and then through... The reverse transmission between the first toothed plate 307 and the first gear 308 drives the control board 306 to move the pusher plate 3 to the left, thereby realizing the pushing operation of the pot ear 001. That is, the function of the control mechanism is to simultaneously move the pot ear 001 to the welding positions on both sides of the pot body 002 when the transfer table 1 moves the pot body 002 to the front positioning. After the welding process is completed, the transfer table 1 moves backward to reset, and the first reset spring 303 resets the hinge seat 302 on the side frame 102. The control board 306 and the pusher plate 3 are reset accordingly. At the same time, the first adjusting spring 305 restores the initial relative position of the hinge seat 302 and the mounting part 105.

[0042] See Figure 6 and Figure 7 The equipment also includes a second feeding mechanism for automatically replenishing the pot body 002, which is disposed at the rear of the mounting frame 101. The second feeding mechanism includes a conveyor 401 fixedly installed at the left rear of the mounting frame 101, which continuously feeds the pot body 002 toward the mounting frame 101; a mounting frame 402 fixedly installed above the rear of the mounting frame 101; and support frames 403 slidably installed on the front and rear sides of the mounting frame 402. The inner sides of the two support frames 403 are provided with support parts 404, and the support frames 403 use the support parts 404 to support the edge of the pot body 002. A contact part 405 is fixedly installed below the rear support frame 403. The displacement of the transfer table 1 will contact the contact part 405 and apply pressure to control the displacement of the support frame 403. A second return spring 406 is fixedly installed between the support frame 403 and the mounting frame 402. Second toothed plates 407 are fixedly installed on the left and right sides of the two support frames 403 respectively. Second gears 408 are rotatably installed on the left and right sides of the mounting frame 101. Each second gear 408 simultaneously meshes with the second toothed plates 407 on the corresponding front and rear support frames 403 to form a symmetrical reverse transmission structure.

[0043] The conveyor 401 is started to continuously transport the pot body 002. The pot body 002 will eventually be pushed onto the support frame 403 and supported by the support part 404. At this time, the pot body 002 will be directly above the rear of the mounting frame 101. When the transfer table 1 moves to the rear of the mounting frame 101, it contacts the contact part 405 and applies pressure, controlling the rear support frame 403 to move backward. Then, through the reverse transmission structure of the second gear 408 and the second toothed plate 407, the front support frame 403 is controlled to move forward synchronously. The two support frames 403 will then separate from each other, and the second return spring 406 will be compressed, causing the two... The increased spacing between the support parts 404 allows the pot body 002 to detach from the support parts 404 and fall naturally. Subsequently, guided by the pad 103, it will accurately and stably cover the pad 103, realizing automatic feeding of the pot body 002. When the transfer table 1 moves forward and disengages from the contact part 405, the second return spring 406 releases its stored energy and resets the two support frames 403 to the initial spacing, restoring the support function of the support parts 404 on the pot body 002, so that the pot body 002 being transported subsequently can be supported. In summary, the second conveying mechanism will realize automatic feeding of the pot body 002 by controlling the transfer rhythm of the transfer table 1.

[0044] See Figures 8-9The transfer platform 1 is rotatably mounted between two mounting parts 105. A pad 103 is provided on both the upper and lower sides of the transfer platform 1. The pad 103 has an arc surface to guide the pot body 002 to accurately and stably cover the pad 103. The device also includes: ratchet wheels 501 fixedly mounted on the rotating shafts on both sides of the transfer platform 1; and rotating assembly units respectively located on both sides of the mounting frame 101. The rotating assembly includes: a mounting box 502 fixedly mounted in the middle of the mounting frame 101; a pawl 503 rotatably mounted inside the mounting box 502. When the transfer platform 1 moves backward, it will cause the ratchet wheels 501 to contact the pawl 503. The number of pawls 503 is set to match the ratchet wheels 501, controlling the ratchet wheels 501 to rotate 180 degrees; and a return torsion spring 504 fixedly mounted between the pawl 503 and the mounting box 502.

[0045] When the transfer platform 1 moves forward, and the ratchet 501 contacts the pawl 503, the pawl 503 is squeezed into the mounting box 502 and rotates because its teeth are aligned with the direction of the pawl 503. After the ratchet 501 leaves, it is automatically reset by the reset torsion spring 504, allowing the ratchet 501 to pass smoothly without rotation. The transfer platform 1 moves forward steadily, ensuring that the pot body 002 is stably transported to the welding station. When the transfer platform 1 moves backward, the ratchet 501 is in the opposite direction to the pawl 503. Therefore, the pawl 503 will lock the ratchet 501 and make it rotate 180 degrees. The transfer platform 1 will then rotate, and the pot body 002 on it will fall naturally, realizing the automatic unloading of the pot body 002.

[0046] See Figure 10 The equipment also includes: a stabilizing assembly disposed between the transfer platform 1 and the mounting part 105, which is used to stabilize the relative position between the transfer platform 1 and the mounting part 105, so that the transfer platform 1 can stably transport the pot body 002. The stabilizing assembly includes: ball grooves 505 symmetrically opened on the inner walls of the mounting parts 105 on both sides; ball shafts 506 slidably installed on the left and right sides of the transfer platform 1, with the position of the ball shafts 506 corresponding to the ball grooves 505 when the transfer platform 1 is in a horizontal state; and a compression spring 507 fixedly installed between the ball shafts 506 and the ball grooves 505, which presses the ball shafts 506 into the ball grooves 505.

[0047] The compression spring 507 uses deformation to store force and press the ball shaft 506 into the ball groove 505, thereby forming a three-point positioning, which makes the transfer table 1 stably keep horizontal. When the transfer table 1 is flipped, the ball shaft 506 will first disengage from the ball groove 505, and after the transfer table 1 is flipped, it will cooperate with the ball groove 505 at another position on the mounting part 105, and accurately position the horizontal position of the transfer table 1 again, thereby ensuring the stability of the horizontal state of the transfer table 1 after rotation.

The guide frame 603 moves forward and backward; a second adjusting spring 607 is fixedly installed between each adjusting plate 606 and the corresponding guide frame 603, the elastic coefficient of the second adjusting spring 607 is greater than the elastic coefficient of the third return spring 605; a fixed frame 608 is fixedly installed on the left and right sides of the front of the mounting frame 101; a push block 609 is slidably installed on each fixed frame 608, the push block 609 moves forward and backward relative to the fixed frame 608, and a wedge block 610 is provided at the front of the push block 609; a hook 611 is slidably installed on each fixed frame 608, the hook 611 moves left and right relative to the fixed frame 608; a fourth return spring 612 is fixedly installed between each fixed frame 608 and the corresponding hook 611, and each wedge block 610 contacts the corresponding hook 611 to realize transmission control; a mating plate 613 is fixedly installed at the front of each guide frame 603, and the hook 611 will hook with the corresponding mating plate 613 to limit the forward displacement of the guide frame 603.

[0049] See Figure 13 The control board 306 is slidably connected to the pusher plate 3. The equipment also includes a third adjusting spring 614 fixedly installed between the control board 306 and the pusher plate 3.

[0050] Because the sidewalls of the pot body 002 are curved, when positioning the pot body 002 and the pot ears 001, the pot body 002 must be positioned first, and then the pot ears 001 must be moved to both sides of the pot body 002 to prevent the displacement of the pot body 002 from squeezing and changing the position of the pot ears 001. Therefore, an adjustment mechanism is used to adjust the conveying sequence between the pot body 002 and the pot ears 001.

[0051] When the transfer platform 1 moves forward on the pot body 002, the pusher plate 3 simultaneously pushes the pot ears 001 to move to both sides of the pot body 002. The pot ears 001 will first contact the baffle 6. At this time, the distance between the control plate 306 and the pusher plate 3 decreases, and the third adjusting spring 614 is compressed and stores energy. When the transfer platform 1 approaches the front of the mounting frame 101, it will first contact the adjusting plate 606. Since the mating plate 613 is restricted by the hook frame 611, the position of the guide frame 603 is locked. The adjusting plate 606 will be displaced relative to the guide frame 603, and the second adjusting spring 607 will be compressed and store elastic potential energy. This stage is the energy storage stage, which makes the subsequent action have a delayed release. When the transfer platform 1 continues to move to contact the push block 609, the inclined block 610 on the push block 609 will move the hook frame 61. 1. When the fourth return spring 612 is compressed, the hook 611 disengages from the mating plate 613. The hook 611 is then reset by the fourth return spring 612. At the same time, the transfer table 1 completes all forward movement and stops displacement. Therefore, after the mating plate 613 is released from the restraint of the hook 611, the second adjusting spring 607 pushes the guide frame 603 forward. When the third return spring 605 is compressed, the toothed frame 604 rotates the baffle 6 away through the third gear 602. The third adjusting spring 614 immediately releases energy to push the pusher plate 3, completing the final positioning of the pot ear 001. By adjusting the timing of the pot body 002 and the pot ear 001, it is ensured that the pot ear 001 is pushed only after the pot body 002 has stopped, thus improving the positioning accuracy between the two.

[0052] When the transfer table 1 moves backward, each structure resets: the third adjusting spring 614 restores the distance between the control plate 306 and the push plate 3, the control plate 306 drives the push plate 3 to reset, the third reset spring 605 resets the baffle 6 through the reset guide frame 603 and the toothed frame 604, during which the mating plate 613 moves backward to squeeze the hook frame 611, so that the hook frame 611 is adjusted to the front side of the mating plate 613 and re-engages the mating plate 613, the second adjusting spring 607 resets the relative position between the adjusting plate 606 and the guide frame 603, and the push block 609 automatically resets through the inclined surface of the inclined block 610.
