Description

Technical Field

[0001] This utility model belongs to the field of welding electrode management and distribution technology, specifically relating to a welding electrode sorting and storage mechanism and a welding electrode dispensing device. Background Technology

[0002] Currently, the sorting, storage, and distribution of welding electrodes are typically handled by a single custodian, allowing for only a single-threaded operation. When multiple welders need to collect electrodes simultaneously, they must queue and collect them one by one, which cannot meet the needs of multi-threaded, multi-window simultaneous distribution. Furthermore, it suffers from the following shortcomings:

[0003] 1. High labor costs: Professional warehouse keepers need to be trained for sorting, storage, and distribution operations;

[0004] 2. Insufficient accuracy: The type and quantity of welding rods during sorting, storage and issuance rely on manual verification. If the issuance quantity is calculated based on 50 welding rods per issuance, the warehouse keeper has to count and verify the quantity of 50 welding rods and their specifications and materials. This is not only time-consuming, but also prone to errors in quantity and specifications when multiple welders are queuing to receive the welding rods during peak periods.

[0005] 3. Time constraints: It cannot achieve 24-hour continuous operation and is difficult to adapt to all-weather production needs. Night shifts and emergency repairs require the warehouse keeper to be on-site before the goods can be issued, which greatly reduces the timeliness.

[0006] To address this, welding material dispensing machines have been designed, such as the structure disclosed in Chinese patent application publication number CN110282333A, to overcome the shortcomings of traditional dispensing methods, save labor costs, and improve dispensing efficiency. Utility Model Content

[0007] The first technical problem this invention aims to solve is to provide a sorting and storage mechanism for welding rods that eliminates the need for manual verification, thereby improving the efficiency of welding rod sorting and storage while reducing human error.

[0008] The second technical problem to be solved by this utility model is to provide a welding rod dispensing device having the above-mentioned sorting and storage mechanism.

[0009] The technical solution adopted by this utility model to solve the first technical problem mentioned above is: a sorting and storage mechanism for welding electrodes, comprising:

[0010] Storage box;

[0011] Its features include:

[0012] A first conveyor belt for placing and conveying welding rods, wherein the conveying direction of the first conveyor belt is defined as the left-right direction, and a first component is provided above the first conveyor belt for arranging the welding rods extending forward and backward along the left-right direction on the first conveyor belt.

[0013] Two discharge plates are erected below the output end of the first conveyor belt, and the surfaces of the two discharge plates are spaced apart to form a discharge channel extending forward and backward. The upper port of the discharge channel is used to receive the welding rods output from the first conveyor belt, and the lower port of the discharge channel is used to output each welding rod one by one in sequence.

[0014] The sorting component is used to receive several welding rods output from the lower port of the discharge channel and to arrange the welding rods in the storage box (210) after passing through the opening (211).

[0015] This invention, through the cooperation of a storage box, a first conveyor belt, two discharge plates, and a sorting component, enables automatic sorting and storage of welding rods, improving efficiency. The first conveyor belt and the two discharge plates sequentially output single welding rods, while the sorting component arranges several welding rods output from the two discharge plates into the storage box. This makes the number of welding rods in the storage box known (e.g., 10 welding rods in a single storage box), eliminating the need for manual verification and reducing human error. When welding rods need to be dispensed, the appropriate number of storage boxes are removed, and the welding rods are detached from the boxes, facilitating efficient and accurate subsequent welding rod dispensing.

[0016] Preferably, the first component includes:

[0017] Two rods extending to the left and right are arranged opposite each other above the first conveyor belt to form a space for the welding rods extending to the left and right to be arranged in the left and right direction.

[0018] Two telescopic power components act on their respective corresponding rods to drive the rods to move back and forth.

[0019] The cooperation of the two rods can neatly arrange the welding rods on the first conveyor belt. Under the action of the first conveyor belt, the welding rods can enter the discharge channel between the two discharge plates in sequence.

[0020] Preferably, the two discharge plates are arranged in a V-shape, resulting in a larger upper end and a smaller lower end of the discharge channel. The first discharge plate is fixed, while the second discharge plate is movable relative to the first, allowing the spacing between the two discharge plates to be adjusted. The V-shaped arrangement of the discharge plates facilitates the sliding of the welding rod along the plate surface, and the spacing between the two discharge plates can be adjusted according to the diameter of the welding rod, thereby ensuring that a single welding rod is output sequentially through the discharge channel.

[0021] To make the spacing between the two discharge plates adjustable, both discharge plates can be designed as movable plates.

[0022] Preferably, the second discharge plate is constrained on the first discharge plate by multiple telescopic rods, and two telescopic rods arranged at intervals in front and behind form a group of telescopic components. There are at least two groups of telescopic components, which are arranged in the vertical direction, and a space for the welding rod to pass through is formed between the two telescopic rods in each group of telescopic components.

[0023] The welding rods entering the discharge channel can pass downwards between the two telescopic rods. In other words, the telescopic rods also serve as guides and limiters.

[0024] In the above solution, preferably, the opening is located on the side wall of the storage box.

[0025] Preferably, the opening is strip-shaped to allow multiple welding rods to enter and exit the storage box simultaneously. The opening is equipped with an elastically deformable baffle. The baffle opens under the action of the ends of the welding rods, allowing multiple rods to pass through simultaneously. After the welding rods have passed through the opening, the baffle returns to its original position under its own elastic force, blocking the opening. In this case, when the welding rods are inside the storage box, the baffle prevents the welding rods from accidentally detaching from the storage box.

[0026] Furthermore, the storage box is flat, and both of its side walls in the length direction are provided with the aforementioned openings extending in the width direction of the storage box.

[0027] To better constrain the welding rods and ensure they are neatly arranged inside the storage box, the inner wall of the storage box is further provided with multiple spaced strip-shaped grooves, with each strip-shaped groove having its two ends facing its corresponding opening, so that each welding rod is constrained within its corresponding strip-shaped groove.

[0028] Preferably, the sorting component includes:

[0029] Two comb plates, designated as the first comb plate and the second comb plate, are arranged facing each other, one above the other. The teeth in each comb plate extend forward and backward and are spaced apart in the left-right direction, creating a feeding channel between adjacent teeth for a single welding rod to pass through. Simultaneously, the two comb plates can generate relative displacement in the left-right direction under the drive of the driving component, exhibiting the following two states:

[0030] The material feeding channels on the first comb plate are staggered from the material feeding channels on the second comb plate, thereby blocking the passage of welding rods and causing several welding rods output from the discharge part to be arranged sequentially in the left-right direction on the comb plate.

[0031] The material feeding channels on the first comb plate are aligned with the material feeding channels on the second comb plate, so that several welding rods arranged on the comb plate can pass through the two comb plates.

[0032] The sorting components also include:

[0033] The transfer trough, located below the two comb plates, has multiple strip-shaped grooves extending forward and backward and arranged in the left and right directions with their openings facing upward. It is used to receive several welding rods passing through the two comb plates, so that each welding rod is located in its corresponding strip-shaped groove.

[0034] The first pusher is located on both sides of the transfer groove, one in front of the other and the other behind the storage box. The first pusher is used to push several welding rods on the transfer groove into the storage box simultaneously through the opening.

[0035] The technical solution adopted by this utility model to solve the second technical problem mentioned above is: a welding rod dispensing device, characterized by having a sorting and storage mechanism as described above.

[0036] Compared with existing technologies, the advantages of this utility model are as follows: This utility model, through the cooperation of a storage box, a first conveyor belt, two discharge plates, and a sorting component, can achieve automatic sorting and storage of welding rods, improving efficiency. Furthermore, the sequential output of single welding rods by the first conveyor belt and the two discharge plates, along with the sorting component arranging several welding rods output from the two discharge plates into the storage box, makes the number of welding rods in the storage box known (e.g., 10 welding rods in a single storage box), thus eliminating the need for manual verification and reducing human error. When welding rods need to be dispensed, the appropriate number of storage boxes are removed, and the welding rods are detached from the storage boxes, facilitating efficient and accurate subsequent welding rod dispensing.

[0043] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0044] like Figures 1-6 The diagram shows a preferred embodiment of a welding electrode sorting and storage mechanism and a welding electrode dispensing device according to this utility model. Since the welding electrode sorting and storage mechanism is only one part of the welding electrode dispensing device, to facilitate understanding of the structure and working principle of the welding electrode sorting and storage mechanism, the structure of each mechanism will be described below using the preferred welding electrode movement sequence in the welding electrode dispensing device. Specifically, the welding electrode dispensing device includes a sorting and storage mechanism, a storage mechanism 300, a feeding mechanism 400, and a receiving mechanism 500.

[0045] The sorting and storage mechanism includes a replenishment mechanism 100 and a sorting mechanism 200.

[0046] The feeding mechanism 100 has a feeding window 120 for receiving welding rods and a discharge component 110 for driving each welding rod to be output sequentially and individually from the feeding mechanism 100. Specifically, the discharge component 110 includes a first conveyor belt 111 and a discharge plate 112. The conveyor belt 111 is used to place and transport welding rods. The transport direction of the first conveyor belt 111 is defined as the left-right direction. Above the first conveyor belt 111 is a first component for arranging the welding rods extending forward and backward along the left-right direction on the first conveyor belt 111. The first component includes two left-right extending rods 114, arranged one in front of the other and one behind the other above the first conveyor belt 111 to form a space for arranging the welding rods extending forward and backward along the left-right direction. The first component also includes two telescopic power components 115 (such as existing electric cylinders, pneumatic cylinders, hydraulic cylinders, etc.), which act on their respective corresponding rods 114 to drive the rods 114 to move back and forth. There are two discharge plates 112, erected below the output end of the first conveyor belt 111. The surfaces of the two discharge plates 112 are spaced apart to form a discharge channel 113 extending forward and backward. The upper port of the discharge channel 113 is used to receive welding rods output from the first conveyor belt 111, and the lower port of the discharge channel 113 is used to output welding rods. The distance between the surfaces of the two discharge plates 112 is adjustable so that each welding rod is output sequentially, one at a time, from the lower port of the discharge channel 113. In this embodiment, the two discharge plates 112 are arranged at an included angle in a V-shape, resulting in a larger upper port and a smaller lower port of the discharge channel 113. The first discharge plate 1121 is fixed, while the second discharge plate 1122 is movable relative to the first discharge plate 1121, allowing the distance between the surfaces of the two discharge plates 112 to be adjusted. Specifically, the vertical length of the second discharge plate 1122 is less than the horizontal length of the first discharge plate 1121. The second discharge plate 1122 can be constrained to the first discharge plate 1121 by four telescopic rods 116. Two pairs of telescopic rods 116 arranged at intervals form a telescopic assembly, and two sets of telescopic assemblies are arranged vertically, resulting in a rectangular array of four telescopic rods 116. The angle between the two discharge plates and the spacing between their surfaces can be adjusted by extending and retracting these two sets of telescopic assemblies. Welding rods entering the discharge channel 113 can pass downwards between the two telescopic rods 116. Thus, the telescopic rods also serve as guides and limiters. To count the number of welding rods passing through the discharge channel 113, photoelectric induction counters can be installed at the upper and lower ports of the discharge channel 113.

[0047] The sorting mechanism 200 described above has a storage box 210 and a sorting component 220 for receiving a plurality of welding rods output from the discharge component 110 so that the plurality of welding rods are arranged in the storage box 210.

[0048] The storage box 210 is flat, and its two side walls along its length have strip-shaped openings 211 extending along the width of the storage box to allow welding rods to enter and exit. Each opening 211 has an elastically deformable baffle 212. The baffle 212 opens the corresponding opening 211 under the action of the welding rod end to allow the welding rod to pass through. After the welding rod passes through the opening, the baffle 212 returns to its original position under its own elastic force and blocks the corresponding opening 211. At this time, when the welding rod is inside the storage box, the baffle 212 can prevent the welding rod from accidentally leaving the storage box. At the same time, in order to better constrain the welding rods and make them neatly arranged in the storage box 210, the inner wall surface of the storage box 210 has multiple spaced strip-shaped grooves 213 to constrain each welding rod in its corresponding strip-shaped groove 213. Meanwhile, the upper and lower surfaces of the storage box 210 are provided with matching protrusions 214 and strip slots 215, so that when two adjacent storage boxes are stacked, they can be inserted through the corresponding protrusions 214 and strip slots 215.

[0049] The sorting component 220 includes a comb plate, a transfer trough 225, and a first pusher 227. There are two comb plates, designated as the first comb plate 221 and the second comb plate 222, arranged opposite each other, one above the other. The teeth 223 in each comb plate extend forward and backward and are spaced apart in the left-right direction, forming a feeding channel 224 between adjacent teeth 223 for a single welding rod to pass through. Simultaneously, the two comb plates can generate relative displacement in the left-right direction under the drive of a driving component (which can be an existing electric cylinder, pneumatic cylinder, hydraulic cylinder, etc.), and have the following two states:

[0050] The material feeding channels on the first comb plate 221 are staggered from the material feeding channels on the second comb plate 222, thereby blocking the passage of welding rods and causing several welding rods output from the discharge part 110 to be arranged sequentially in the left-right direction on the comb plate.

[0051] The material feeding channels on the first comb plate 221 are aligned with the material feeding channels on the second comb plate 222, so that several welding rods arranged on the comb plate can pass through the two comb plates.

[0052] Similarly, existing photoelectric sensors can be installed near the comb plate. When the photoelectric sensors detect that the required number of welding rods are arranged on the comb plate, the two comb plates can be driven to move relative to each other until the material feeding channels on the first comb plate 221 are aligned with the material feeding channels on the second comb plate 222.

[0053] The transfer slot 225 is located below the two comb plates and has multiple strip slots 226 extending forward and backward and arranged in the left and right direction with the slot opening facing upward. It is used to receive several welding rods passing through the two comb plates so that each welding rod is located in its corresponding strip slot 226.

[0054] The first pusher 227 and the storage box 210 are located on opposite sides of the transfer groove 225, one in front of the other. The first pusher 227 is used to simultaneously push several welding rods on the transfer groove 225 into the storage box 210 through the opening 211. In this embodiment, the first pusher 227 includes a pusher plate extending left and right and a first telescopic member for driving the pusher plate to move back and forth. The first telescopic member can be an existing electric cylinder, pneumatic cylinder, hydraulic cylinder, etc. The cooperation between the first telescopic member and the pusher plate can simultaneously push several welding rods on the transfer groove 225 into the storage box 210.

[0055] The aforementioned storage mechanism 300 has a storage compartment 310 and a conveyor 320 for storing a storage box 210 containing a number of welding rods into the storage compartment 310.

[0056] Storage compartment 310 has a vertically extending storage cavity 311 for multiple storage boxes 210 to be stacked sequentially. The top of the storage cavity 311 has an opening for the storage boxes 210 to enter, and the bottom of the storage cavity 311 has an opening that can be opened and closed for the storage boxes 210 to exit. Similarly, a photoelectric sensor counter can be installed at the bottom of the storage cavity 311 to identify the number of storage boxes 210 exiting from the storage cavity 311. The inner wall of the storage cavity 311 is provided with a buffer, including two vertically arranged, wavy, elastic buffer strips 312, which are arranged opposite each other within the storage cavity 311 to slow down the falling speed of the storage boxes 210 within the storage cavity 311. In this embodiment, each storage compartment 310 has multiple storage cavities 311, arranged side-by-side in a horizontal direction (e.g., ...). Figure 1 , 4 (in the left and right directions). In this embodiment, there are multiple storage compartments 310 arranged side by side (not shown in the figure, each storage compartment 310 can be arranged in the front and back direction). Each storage compartment 310 has an entrance 313 on one of its left and right side walls for the storage box to enter, and the entrance 313 is located above the storage cavity 311.

[0057] The aforementioned conveyor 320 is used to selectively store the storage boxes 210 into the storage compartment 310. The conveyor 320 includes a second conveyor belt 321 and a third pusher 322. The second conveyor belt 321 is used to transport the storage box containing several welding rods to the entrance 313 of the corresponding storage compartment 310. The third pusher 322 is located near the entrance 313 of the storage compartment 310 and is used to push the storage box transported to the entrance 313 into the storage cavity 311. In this embodiment, the third pusher 322 is a telescopic member capable of extending and retracting left and right. The third telescopic member can be an existing electric cylinder, pneumatic cylinder, hydraulic cylinder, etc.

[0058] In actual use, such as Figure 4As shown, the storage boxes entering the storage compartment 310 from the left entrance 313 first enter the leftmost storage cavity 311. After the leftmost storage cavity 311 is filled with stacked storage boxes, the upper surface of the topmost stacked storage box can serve as a support surface, so that the storage boxes entering from the entrance 313 later first pass through the support surface and then enter the second storage cavity 311 on the left, and so on, until all the storage cavities 311 in the storage compartment 310 are filled with stacked storage boxes.

[0059] Meanwhile, in this embodiment, each storage compartment 310 is equipped with a temperature control mechanism 330 for baking and heat preservation of the welding rods.

[0060] The aforementioned unloading mechanism 400 is used to receive the storage box 210 output from the storage compartment 310, and has an unloading component 410 for detaching each welding rod inside the storage box 210 from the storage box 210. In this embodiment, the unloading mechanism 400 includes a third conveyor belt 420 for receiving the storage box 210 output from the storage compartment 310 and conveying the storage box 210 to the location of the unloading component 410. The aforementioned unloading component 410 includes a magnetic suction component 411 for fixing the storage box 210 and a second pusher component 412. The second pusher component 412 is used to extend into one of the openings of the storage box 210 to simultaneously detach each welding rod inside the storage box 210 through the other opening. The structure of the second pusher component 412 can be referenced to the design of the first pusher component 227, and will not be described in detail here. To ensure that the collection box 210, after the welding rods have detached, can return to the sorting mechanism 200, this embodiment also includes a fourth conveyor belt 430. The input end of the fourth conveyor belt 430 is located below the unloading member 410 and is used to receive the collection box 210 ejected by the ejector member 413. The output end of the fourth conveyor belt 430 is located behind the transfer trough 225, so that the collection boxes on the fourth conveyor belt 430 can re-receive the welding rods on the transfer trough 225. In this embodiment, the ejector member 413 can be an existing electric cylinder, pneumatic cylinder, hydraulic cylinder, etc. The extension and retraction direction of the ejector member 413 is perpendicular to the extension and retraction direction of the second pushing member 412, so that they can work independently without interfering with each other. For details, please refer to [link to relevant documentation]. Figure 5 , 6 .

[0061] And such as Figure 1 As shown, in this embodiment, the output end of the fourth conveyor belt 430 and the input end of the second conveyor belt 321 are arranged one above the other, with a polygonal structure (such as...) between them. Figure 1The hexagonal turntable 330 rotates 180° around its central axis to transfer the storage box output from the fourth conveyor belt 430 to the input end of the second conveyor belt 321. Each side of the turntable 330 is designed to be magnetic to magnetically attract the storage box onto the turntable. Once the storage box on the turntable is above the fourth conveyor belt 430, it detaches from the turntable under its own gravity and sits on the fourth conveyor belt 430.

[0062] The aforementioned material requisition mechanism 500 is used to receive welding rods from the unloading mechanism 400 and has a material requisition window 510 for users to collect welding rods. In this embodiment, multiple material requisition windows 510 can be provided and arranged side by side, and each material requisition window is correspondingly provided with the aforementioned unloading mechanism 400. Each unloading mechanism 400 can operate simultaneously to ensure that the welding rods are delivered to their respective corresponding material requisition windows.

[0063] The electrode dispensing device of this embodiment has the following technical advantages:

[0064] ① Multi-threaded efficient distribution: Supports multiple material requisition windows for concurrent operation (510), improving the efficiency of welding rod distribution;

[0065] ②Full-process automation: From welding electrode sorting and storage to material unloading, the entire process is automated, reducing manual intervention;

[0066] ③ Precise control: Photoelectric sensors and intelligent algorithms ensure zero errors in the type and quantity of welding materials;

[0067] ④ 24-hour continuous operation: meets the all-weather operation needs of industrial scenarios and reduces labor costs.

[0068] In the specification and claims of this utility model, terms indicating direction, such as "front," "rear," "upper," "lower," "left," "right," "side," "top," and "bottom," are used to describe various exemplary structural parts and elements of this utility model. However, the use of these terms is merely for the purpose of explanation and is based on the exemplary orientations shown in the accompanying drawings. Since the embodiments disclosed in this utility model can be arranged in different orientations, these terms indicating direction are for illustrative purposes only and should not be regarded as limitations. For example, "upper" and "lower" are not necessarily limited to directions opposite to or consistent with the direction of gravity.

[0069] The term "vertical" is also used in the specification and claims of this utility model, meaning basically along the up and down direction, and is not limited to just the vertical direction, but can also be slightly deviated from the vertical direction.
