Description

Technical Field

[0001] This utility model relates to the field of feeding equipment technology, and in particular to an automatic welding machine feeding device. Background Technology

[0002] In the assembly of some components, welding is required to connect different parts, such as pipes and fittings, where the fittings need to be welded onto the pipes. Currently, manual feeding and welding are mostly used, which is inefficient. To improve production efficiency, and considering the need to feed multiple different components simultaneously, as well as the different specifications and sizes of pipes and fittings, an automatic welding machine feeding device is provided to solve the above problems. Utility Model Content

[0003] The technical problem to be solved by this utility model is: in order to overcome the shortcomings of the prior art, this utility model provides an automatic welding machine feeding device.

[0004] The technical solution adopted by this utility model to solve its technical problem is: an automatic welding machine feeding device, including a pipe feeding part and a head feeding part, wherein the pipe feeding part includes a hopper, a pushing mechanism and a positioning mechanism, and the head feeding part includes a vibrating plate, a vibrating rail and a positioning clamping mechanism. The hopper is used to hold pipes, and its bottom is provided with a discharge port that allows the pipes to pass through. The bottom surface of the hopper is inclined from back to front to facilitate the automatic discharge of the pipes under the action of gravity. The pushing mechanism is set at the discharge port to push the pipes at the discharge port outward. The positioning mechanism is connected to the hopper and located on both sides of the discharge port. It can push the pipes pushed out by the pushing mechanism to a fixed position, wait for the mechanical chuck to grab the fixed position, and move the pipes to the next process of the automatic welding machine.

[0005] The vibratory feeder is used for feeding the head. It has a base plate at its bottom and is connected to the base plate by adjustable screws. The height of the vibratory feeder can be adjusted by adjusting the screws to match the height of the vibratory material rail. The outlet of the vibratory feeder is connected to one end of the vibratory material rail, which is located at the front of the hopper. The bottom of the vibratory material rail is connected to the base plate by a vibrating seat. The positioning and clamping mechanism is connected to the end of the vibratory material rail and is located in front of the fixed position of the pipe. It is used to clamp the head and raise it to a specified height, waiting for the mechanical chuck to grab it at the specified height and move the head to the next process of the automatic welding machine.

[0006] Because pipes come in various lengths, the hopper includes a housing and partitions to cover all existing product specifications. The partitions are located inside the housing and their position within the housing is adjustable. The housing size covers the longest existing pipe length. The hopper features adjustable partitions, allowing for free adjustment according to different pipe lengths, and the housing has sufficient space to accommodate the pipes for an entire batch of work orders.

[0007] Furthermore, the pushing mechanism includes a support plate and a pushing cylinder. The support plate is located at the bottom of the hopper and fixed above the support side plate, with an opening on the side facing the hopper outlet. The pushing cylinder is fixed below the support plate, with its push rod extending forward and connected to a transition plate at its end. A pushing base plate is connected above the transition plate, and the front end of the pushing base plate has a pushing positioning groove. The pushing base plate at the front end of the pushing positioning groove is tilted upwards to a certain height, exceeding the upper surface of the pushing base plate, to block the pipe and prevent it from falling due to inertia and pushing force. The front side of the transition plate also has a forward-extending limiting post to limit the forward pushing distance and prevent excessive stroke. A pushing baffle is also located on the hopper above the pushing base plate to block the pipe at the outlet, ensuring that only one pipe is output at a time. Preferably, the height of the pushing baffle can be adjusted to accommodate pipes of different diameters.

[0008] Furthermore, the positioning mechanism includes a positioning cylinder and a connecting plate. The positioning cylinder is fixed to the front side of the hopper via the connecting plate, and the connecting plate is provided with several cylinder adjustment holes for adjusting the fixed position of the positioning cylinder left and right to accommodate positioning of pipes of different lengths. A vertical positioning push block is connected to the left side of the push rod of the positioning cylinder. A left and right carrier plate are provided below the positioning push block, and the left and right carrier plates are located on the left and right sides of the pusher base plate, respectively. A positioning stop block is provided on the left carrier plate. The positioning stop block and the positioning push block are directly opposite each other, and can respectively hold the two ends of the pipe during positioning.

[0009] When the pipe is relatively long, there is a risk of it falling off the pusher plate when it is pushed forward. Therefore, the left and right carrier plates are further provided with positioning baffles on their front sides. The positioning baffles can assist the pusher plate in blocking the pipe, thereby preventing the pipe from falling and improving reliability.

[0010] Furthermore, the vibratory feeder includes a vibratory chamber, a vibrating mechanism at the bottom of the vibratory chamber, a circumferential guide trough inside the vibratory chamber, the end of the guide trough being connected to the vibrating material rail, and multiple online detection mechanisms inside the vibratory chamber for detecting the direction of the head.

[0011] Furthermore, the positioning and clamping mechanism includes a clamping cylinder, a lifting cylinder, and a lifting support column. The lifting cylinder is fixedly connected to the side of the lifting support column, and the bottom of the lifting support column is fixed to the ground or other equipment platform. The push rod end of the upper end of the lifting cylinder is fixedly connected to a horizontal lifting plate. The clamping cylinder is fixed on the lifting plate. The clamping cylinder has a gripper on its actuating end. The gripper includes an upper V-shaped gripper finger and a lower V-shaped gripper finger that are opposite each other, and V-shaped grooves are provided on the opposite sides. The head is clamped by the upper V-shaped gripper finger and the lifting cylinder drives it to a specified height, waiting to be grasped.

[0012] Furthermore, the gripper is equipped with a material presence detection sensor on the side facing the vibrating material rail. The material presence detection sensor is mounted on the lifting support column via a sensor bracket. The material presence detection sensor detects whether there is a head at the end of the vibrating material rail. After detecting the presence of material, the positioning and clamping mechanism is activated to clamp the head. Then, the lifting cylinder drives the lifting platform to rise to the designated height, that is, it drives the head to the designated height, waiting to be grabbed.

[0013] Furthermore, a moving mechanism is provided below the hopper. The moving mechanism includes a guide rail, a slider, a moving carrier plate, a handle, and a moving positioning block. The moving carrier plate is located below the hopper, and the hopper is connected to the upper part of the moving carrier plate via a supporting side plate. Two parallel guide rails are arranged below the moving carrier plate, and the moving carrier plate is slidably connected to the guide rails via a slider. A handle for easy pushing and pulling is also provided on the rear side of the moving carrier plate. The moving positioning block is located on the front side of the moving carrier plate to limit the forward movement of the moving carrier plate.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0030] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0031] like Figure 1 and Figure 2 As shown, this utility model discloses an automatic welding machine feeding device, comprising a pipe feeding section 10 and a head feeding section. After both sections are fed, the pipes are transported to a chuck by mechanical grippers to complete the final welding operation. The pipe feeding section includes a hopper 1, a pushing mechanism 2, and a positioning mechanism 3. The head feeding section includes a vibrating plate 5, a vibrating rail 6, and a positioning clamping mechanism 7. The hopper 1 is used to hold the pipes 10, and its bottom has an outlet for the pipes 10 to pass through. The bottom surface of the hopper 1 is inclined from back to front to facilitate automatic discharge of the pipes 10 under gravity. The pushing mechanism 2 is located at the outlet and is used to push the pipes 10 outwards. The positioning mechanism 3 is connected to the hopper 1 and located on both sides of the outlet. It can push the pipes 10 pushed out by the pushing mechanism 2 to a fixed position, waiting for the mechanical grippers to grab them and move the pipes 10 to the next process of the automatic welding machine.

[0032] like Figure 2As shown, since the pipe 10 has various length specifications, in order to cover all specifications of existing products, the hopper 1 includes a hopper box 1.1 and a partition plate 1.2. The partition plate 1.2 is disposed inside the hopper box 1.1, and its position inside the hopper box 1.1 can be adjusted left and right. In this embodiment, the top of the front and rear side plates of the hopper box 1.1 is provided with several spaced adjustment holes 1.3. During adjustment, the partition plate 1.2 is moved to the corresponding adjustment hole 1.3, and then the two ends of the top of the partition plate 1.2 are connected and fixed to the hopper box 1.1 by connecting pieces 1.4 and screws.

[0033] like Figures 3-5 As shown, the pushing mechanism 2 includes a support plate 2.2 and a pushing cylinder 2.1. The support plate 2.2 is located at the bottom of the hopper 1 and fixed above the support side plate 4.6, with an opening on the side facing the outlet of the hopper 1 to facilitate the back-and-forth movement of the pushing base plate 2.3. The pushing cylinder 2.1 is fixed below the support plate 2.2, with its push rod extending forward and its end connected to a transition plate 2.4. The pushing base plate 2.3 is connected above the transition plate 2.4, and the front end of the pushing base plate 2.3 is provided with a pushing mechanism. The pusher positioning groove 2.7 has a pusher base plate 2.3 at its front end that is raised to a certain height, exceeding the upper surface of the pusher base plate 2.3, to block the pipe 10 and prevent it from falling due to inertia and thrust. The front side of the adapter plate 2.4 is also equipped with a forward-extending limiting post 2.5 to limit the forward pushing distance and prevent excessive travel. Above the pusher base plate 2.3, the hopper 1 also has a pusher baffle 2.6 to block the pipe 10 at the outlet, ensuring that only one pipe 10 is output at a time. Since the pipe 10 has various diameter specifications, the pusher baffle 2.6 can be finely adjusted up and down to ensure that the gap between the pusher baffle 2.6 and the pusher base plate 2.3 is just right for releasing one pipe 10. The pusher positioning groove 2.7 on the pusher base plate 2.3 is preferably a V-shaped groove, which can accommodate the rapid positioning and ejection of pipes 10 of different sizes. Different pusher plates 2.3 can be selected for pipes 10 with different diameters. The pusher plate 2.3 adopts a quick-change structure design, which facilitates quick positioning and quick change of shape.

[0034] like Figure 3 and Figure 4As shown, the positioning mechanism 3 includes a positioning cylinder 3.1 and a connecting plate 3.2. The positioning cylinder 3.1 is fixed to the front side of the hopper 1 via the connecting plate 3.2, and the connecting plate 3.2 is provided with several cylinder adjustment holes 3.7 for adjusting the fixed position of the positioning cylinder 3.1 left and right to accommodate the positioning of pipes 10 of different lengths. A vertical positioning push block 3.4 is connected to the left side of the push rod of the positioning cylinder 3.1, and a left carrier plate 3.5 and a right carrier plate 3.6 are provided below the positioning push block 3.4. The left carrier plate 3.5 and the right carrier plate 3.6 are located on the left and right sides of the pusher base plate 2.3, respectively. The left carrier plate 3.5 is equipped with a positioning block 3.3. The positioning block 3.3 and the positioning push block 3.4 are directly opposite each other. During positioning, they can hold the two ends of the pipe 10. The front sides of the left carrier plate 3.5 and the right carrier plate 3.6 are equipped with positioning baffles 3.8. The positioning baffles 3.8 can assist the pusher base plate 2.3 in blocking the pipe 10, thereby preventing the pipe 10 from falling and improving reliability. The positioning mechanism 3 is composed of a positioning cylinder 3.1, a positioning push block 3.4, and a positioning block 3.3. When the pusher base plate 2.3 is pushed out, the positioning cylinder 3.1 guides the pipe 10 with the V-groove of the pusher base plate 2.3 to the positioning block 3.3, waiting for the mechanical jaws to pick it up.

[0035] like Figure 1 As shown, the vibratory feeder 5 is used for feeding the head 11. It has a base plate 8 at its bottom and is connected to the base plate 8 by adjustable screws. The height of the vibratory feeder 5 can be adjusted by adjusting the screws to match the height of the vibratory material rail 6. The outlet of the vibratory feeder 5 is connected to one end of the vibratory material rail 6. The vibratory material rail 6 is located on the front side of the hopper 1 and the bottom of the vibratory material rail 6 is connected to the base plate 8 by a vibrating seat 9. The positioning and clamping mechanism 7 is connected to the end of the vibratory material rail 6 and is located in front of the fixed position of the pipe 10. It is used to clamp the head 11 and raise the head 11 to a specified height, wait for the mechanical chuck to grab it at the specified height, and move the head 11 to the next process of the automatic welding machine. Specifically, the vibratory feeder 5 includes a vibratory chamber, a vibrating mechanism at the bottom of the vibratory chamber, a guide trough along the circumference inside the vibratory chamber, the end of the guide trough being connected to the vibrating material rail 6, and multiple online detection mechanisms inside the vibratory chamber. The online detection mechanisms are used to detect the direction of the head 11 and remove the head 11 whose direction is inconsistent with the design, ensuring that the head 11 entering the vibrating material rail 6 has the same direction.

[0036] like Figure 2As shown, a moving mechanism 4 is also provided below the hopper 1. The moving mechanism 4 includes a guide rail 4.1, a slider 4.3, a moving carrier plate 4.2, a handle 4.4, and a moving positioning block. The moving carrier plate 4.2 is located below the hopper 1, and the hopper 1 is connected to the upper part of the moving carrier plate 4.2 via a supporting side plate 4.6. The guide rail 4.1 consists of two parallel rails located below the moving carrier plate 4.2, and the moving carrier plate 4.2 is slidably connected to the guide rail 4.1 via the slider 4.3. A handle 4.4 for easy pushing and pulling is also provided on the rear side of the moving carrier plate 4.2. The moving positioning block 4.5 is located on the front side of the moving carrier plate 4.2 and is used to limit the forward movement of the moving carrier plate 4.2. The moving mechanism 4 adjusts the front and rear position of the entire pipe 10 feeding section, thereby facilitating the loading of materials into the hopper 1.

[0037] like Figure 6 As shown, the positioning and clamping mechanism 7 includes a clamping cylinder 7.1, a lifting cylinder 7.2, and a lifting support column 7.3. The lifting cylinder 7.2 is fixedly connected to the side of the lifting support column 7.3, and the bottom of the lifting support column 7.3 is fixed to the ground or other equipment platform. The push rod end of the upper end of the lifting cylinder 7.2 is fixedly connected to a horizontal lifting platform 7.4. The clamping cylinder 7.1 is fixed on the lifting platform 7.4. The actuating end of the clamping cylinder 7.1 is provided with a gripper. The gripper includes an upper V-shaped gripper finger 7.5 and a lower V-shaped gripper finger 7.6 that are opposite each other, and V-shaped grooves are provided on the opposite sides. The V-shaped groove structure makes the positioning more accurate and the clamping more secure. The head 11 is clamped by the upper V-shaped gripper finger 7.5 and the lower V-shaped gripper finger 7.6, and is driven to a specified height by the lifting cylinder 7.2, waiting to be grasped. The gripper facing the vibrating material rail 6 is also equipped with a material presence detection sensor, which is mounted on the lifting support column 7.3 via a sensor bracket 7.7. The material presence detection sensor detects whether there is a head 11 at the end of the vibrating material rail 6. After detecting the presence of material, the positioning and clamping mechanism 7 is activated to clamp the head 11. Then, the lifting cylinder 7.2 drives the lifting platform 7.4 to rise to a specified height, that is, to bring the head 11 to the specified height, waiting to be gripped. After the material is picked up, the lifting cylinder 7.2 drives the lifting platform 7.4, the clamping cylinder 7.1, and the gripper to fall back, waiting for the next product to be pushed into the gripper.

[0038] To improve the reliability and safety of equipment operation, each mechanical action / step is equipped with real-time detection or mistake-proof design to prevent downtime caused by misoperation or other factors.

[0039] Working principle:

[0040] The entire operation process is as follows: Pipe 10 is placed in hopper 1, pushing mechanism 2 pushes pipe 10 out, positioning mechanism 3 is activated to push pipe 10 to a fixed position, and mechanical jaws clamp it at the fixed position. Head 11 is placed in vibratory feeder 5, vibratory feeder 5 pushes head 11 to vibrating rail 6 through vibration, and the thrust generated by the vibration of subsequent products pushes head 11 along vibrating rail 6 to the positioning position, triggering switch, positioning and clamping mechanism 7 clamps and raises to the specified height, and mechanical jaws clamp head 11 at the specified height.

[0041] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the scope of this utility model.
