[0002] The handle of a flower basket or bucket is a handle or grip used for carrying and transporting flower baskets or buckets. The spot welding equipment for flower baskets and buckets is a device that welds the handle to the flower basket or bucket. Existing spot welding equipment for flower baskets and buckets is generally used in conjunction with a conveyor belt. The conveyor belt transports the flower basket or bucket to the welding workbench. The worker manually adjusts the direction of the flower basket or bucket, rotates it until the two ears are aligned with the welding end of the welding ear mechanism, and then welds it through the welding ear mechanism. The welding ear mechanism is an existing product. The function of the welding ear mechanism is to weld the handle to the bucket body.

[0003] Existing spot welding handles for basket cans have poor functionality. During use, workers need to manually rotate the basket can to align the welding ends of the welding lug mechanism with the two lugs for welding. The positioning accuracy of manual positioning is low, and it increases the workload of workers. Therefore, we propose a welding lug positioning mechanism for spot welding handles of basket cans.

[0026] like Figures 1 to 4 As shown, the present invention relates to a welding ear positioning mechanism for a spot welding handle device for a flower basket bucket, including a can pressing mechanism 1, a rotating worktable 2 is provided vertically below the can pressing mechanism 1, welding ear searching mechanisms 3 are provided on both sides of the can pressing mechanism 1, and a clamping mechanism 4 is provided below the welding ear searching mechanism 3. The clamping mechanism 4 includes a bidirectional drive assembly 6, and can clamps 5 are installed at the power output ends of both ends of the bidirectional drive assembly 6. There are two can clamps 5 and they are symmetrically distributed above the rotating worktable 2. The inner arc of the can clamp 5 corresponds to the arc of the outer arc of the flower basket bucket.

[0027] The welding ear locating mechanism 3 includes a welding ear locating sensor 303. There are two welding ear locating sensors 303, which are symmetrically distributed above the rotary worktable 2. The welding ear locating sensor 303 is a non-contact photoelectric sensor.

[0028] The can clamp 5 includes a clamping member 501. Several grooves 502 are spaced apart at the inner arc end of the clamping member 501. A slider 503 is slidably connected within each groove 502. Both the grooves 502 and the slider 503 are trapezoidal, with the smaller end facing the inner arc end. An arc plate 504 is fixedly installed at the other end of the slider 503. A brake pad 505 is installed on the inner arc surface of the arc plate 504. A limit sleeve 506 is elastically slidably connected to the outside of the clamping member 501. The arc ends of the clamping member 501, arc plate 504, brake pad 505, and limit sleeve 506 correspond in curvature. This utility model utilizes the can pressing mechanism 1 and the rotating worktable 2 for coaxial rotation. The position of the flower basket bucket is automatically adjusted. Through the cooperation of the welding lug mechanism 3 and the clamping mechanism 4, the flower basket bucket stops after the position of the two lugs is adjusted, achieving a more stable stopping state. The brake assembly can be quickly disassembled and assembled, and can quickly and accurately position the two lugs of the flower basket bucket. The inner arc end of the clamp 501 is slidably connected to the arc plate 504 through the sliding assembly with the small end facing the inner arc end. The brake plate 505 is installed on the inner arc surface of the arc plate 504. The clamp 501 is then elastically slidably connected to the limiting sleeve 506 for limiting, which facilitates quick replacement of the easily worn brake assembly, namely the brake plate 505 and the arc plate 504 as a whole.

[0029] Furthermore, the pressure vessel mechanism 1 includes a first mounting bracket 101. A pressure plate body 104 is rotatably mounted on the lower part of the first mounting bracket 101 via a bearing 103. The power input end of the pressure plate body 104 is connected to a pressure plate cylinder 102. A magnetic induction switch 105 is installed on the pressure plate cylinder 102. When the magnetic induction switch 105 on the pressure plate cylinder 102 senses that the tank has been pressed down, it triggers the turntable 202 to rotate, thereby driving the tank to rotate.

[0030] Furthermore, the rotary worktable 2 includes a turntable 202, which is located directly below the pressure plate body 104 and has the same diameter as the pressure plate body 104. The power input end of the turntable 202 is connected to a servo motor 201, which can drive the turntable 202 and the tank on it to rotate.

[0031] Furthermore, the welding ear locating mechanism 3 also includes a second mounting bracket 301. The second mounting bracket 301 has two brackets, each with an L-shaped bracket 302 detachably mounted below it. A welding ear locating sensor 303 is mounted on the L-shaped bracket 302. A sliding frame 304 is fixedly mounted in the middle of the bottom of the L-shaped bracket 302. The welding ear locating sensor 303 is a non-contact photoelectric sensor. An appropriate magnet needs to be installed at the position of the welding ear for it to work effectively. During the rotation of the turntable 202 and the tank on it, the photoelectric sensor can accurately detect the position of the welding ear. Because it is non-contact, physical wear and mechanical interference are avoided.

[0032] Furthermore, the bidirectional drive assembly 6 includes a self-locking double-acting cylinder 603. The power output ends of both ends of the self-locking double-acting cylinder 603 are fixedly mounted with slide rods 601 through connecting brackets 602. The slide rods 601 are slidably connected to the inner side wall of the slide frame 304. The self-locking double-acting cylinder 603 is a cylinder in which the piston moves synchronously in opposite directions or in opposite directions. The movement of the piston in two directions is realized by controlling the inflow and outflow of compressed air.

[0033] Furthermore, the clamp 501 is provided with an adjustment groove 509. A spring 508 is fixedly installed at one end of the adjustment groove 509 away from the inner arc end of the clamp 501. An adjustment rod 507 is fixedly installed at the other end of the spring 508. The adjustment rod 507 is slidably connected in the adjustment groove 509. The adjustment rod 507 is fixedly installed in the limiting sleeve 506, which facilitates quick sliding of the limiting sleeve 506 and quick replacement of the brake assembly composed of the brake pad 505 and the arc pad 504.

[0034] Working Principle: This embodiment provides a welding ear positioning mechanism for a spot welding handle device for flower basket buckets. In use, this utility model uses a can-pressing mechanism 1 in conjunction with a rotating worktable 2 to automatically adjust the position of the flower basket bucket by coaxial rotation. Through the cooperation of a welding ear-finding mechanism 3 and a clamping mechanism 4, the flower basket bucket stops after the two ears are properly positioned, achieving a smoother stop. The brake assembly can be quickly disassembled and assembled, enabling rapid and high-precision positioning of the two ears of the flower basket bucket. The inner arc end of the clamp 501 is slidably connected to an arc plate 504 via a sliding assembly with its small end facing the inner arc end. A brake plate 505 is installed on the inner arc surface of the arc plate 504. The outer arc of the clamp 501... The elastic sliding connection has a limiting sleeve 506 for limiting, which facilitates quick replacement of easily worn brake components, namely the brake pads 505 and the arc pads 504 as a whole. When the basket bucket can is transported to this station by the existing conveyor belt, external power supply is used to control the pressure plate cylinder 102 to open and drive the pressure plate body 104 to move downwards, pressing the can to prevent it from moving. The magnetic switch 105 on the pressure plate cylinder 102 detects that the can has been pressed down (the magnetic switch 105 is usually composed of a reed switch and a permanent magnet, which realizes position detection in a non-contact manner. In the absence of a magnetic field, the switch contacts are in the open state). When the circuit is not flowing and a magnetic field is present, if an object approaches and enters the sensing area (i.e., when a sufficient magnetic field is provided near the contact points), the two contacts will attract and close, forming a conductive state, and the circuit will begin to flow. This information is transmitted to the external control mechanism, which then controls the servo motor 201 to rotate. The servo motor 201 drives the turntable 202 and the tank on it to rotate. There are two welding ear sensors 303, symmetrically distributed above the rotating worktable 2. The welding ear sensors 303 are non-contact photoelectric sensors (photoelectric sensors detect objects by emitting infrared or laser beams and receiving reflected light signals). When the area is in contact with the light source, it may block or reflect the light, causing changes in the output signal of the photoelectric sensor. It is suitable for detecting small objects or complex shapes and is not affected by the type of material. During the rotation of the turntable 202 and the tank on it, the photoelectric sensor can accurately detect the position of the welding ears. Because it is non-contact, it avoids physical wear and mechanical interference. When the welding ear sensor 303 detects the two ears, the servo motor 201 is turned off. The stopping accuracy of the servo motor 201 can usually reach ±0.02°. Even higher stopping accuracy, such as 0.02°, can be achieved in high-precision applications by optimizing the design and using a high-resolution encoder.0.001mm, but the servo motor 201 does not self-lock after stopping. If the mechanical structure where the motor is located has a large inertia after the power is off, the motor may continue to rotate due to inertia. Therefore, the clamping mechanism 4 is needed to correct the position of the basket can while clamping the basket can to achieve a smoother stopping state. When the servo motor 201 is turned off, the external control switch is triggered to control the self-locking double-acting cylinder 603 to shorten at both ends at the same time. The two symmetrically distributed can clamps 5 move synchronously towards each other. Since the inner arc of the can clamp 5 corresponds to the outer arc of the basket can, the can clamps 5 can clamp the basket can by cooperating in pairs. Since the basket can is clamped by the brake pad 505, the basket can is prevented from continuing to rotate or shake while correcting the position of the basket can, achieving a smoother stopping state. This is more conducive to the higher precision welding of the welding ear mechanism. The brake pad 505 is a wear part. When it needs to be replaced, pull the limit sleeve 506 backward to make the limit sleeve 506 slide to the attachment. Figure 4 In the indicated state, the adjusting rod 507 slides backward synchronously within the adjusting groove 509. The spring 508 is compressed and shortened, and the sliding component with its small end facing the inner arc end protrudes. This allows the brake assembly, which is composed of brake pad 505 and arc plate 504, to slide upward or downward. The slider 503 of the new brake assembly is then slid into the groove 502 of the clamp 501. The limiting sleeve 506 is released, and the compressed spring 508 rebounds and resets, causing the limiting sleeve 506 to slide towards the arc surface of the clamp 501, covering the sliding component and limiting the brake assembly composed of brake pad 505 and arc plate 504. This enables quick replacement of easily worn brake components. This equipment is installed on an existing welding ear mechanism (the pressure plate cylinder 102, magnetic switch 105, servo motor 201, welding ear sensor 303, and self-locking double-acting cylinder 603 are all existing products on the market and connected to an external control mechanism).

[0035] The embodiments disclosed herein are preferred embodiments, but are not limited thereto. Those skilled in the art can readily grasp the spirit of this utility model based on the above embodiments and make different extensions and variations. However, as long as they do not depart from the spirit of this utility model, they are all within the protection scope of this utility model.
