Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of welding material storage and dispensing, in particular to a welding rod dispensing device and method. BACKGROUND

[0002] Welding is a material processing method that promotes the atomic combination of welding parts through heating, pressing or both. Currently, welding technology has been widely used in shipbuilding, vehicle manufacturing, power station equipment, petrochemical industry, aerospace, machinery manufacturing, electronic devices and many other industrial fields.

[0003] Welding rods are metal strip-shaped welding materials that serve as filler metal or have both conductive and filler metal functions. The main types of aluminum welding rods include solid welding rods and flux-cored welding rods. In conventional welding operations, thin plates cut into strips with chemical compositions similar to the base material are usually used as filler welding rods when welding aluminum and aluminum alloys.

[0004] In welding construction management, welding material storage quality and receiving and sending management directly affect the stability of the welding process and the quality of the project. In particular, welding rods need to be stored at a specific temperature to prevent moisture and deterioration, and precise counting is required when dispensing to achieve material traceability and cost control. Current welding material management relies on manual work. According to the differentiated needs of customers, the welding rods are cut into specific lengths, then the cut welding rods are manually stored in the heat preservation equipment by the management personnel, and the information is recorded. When dispensing, the manual counting and registration are performed. This mode is the basis for the standard use of welding materials and is also a necessary part of welding construction.

The heating plates can heat the welding rods inside the feeding bin from the upper and lower sides of the feeding bin, and cooperate with the heat preservation layer around the feeding bin to effectively block the heat exchange between the inside and the outside, so as to maintain a constant temperature environment of 70-150 DEG C in the feeding bin, thereby ensuring the storage quality of the welding rods.

[0028] By cooperating the heat preservation layer around the feeding bin with the heating plates, the constant temperature environment is maintained, the temperature in the feeding bin is ensured to be maintained in the required range, and uninterrupted heat preservation is supported, thereby avoiding the performance degradation of the welding rods due to temperature fluctuation and preparing for subsequent delivery.

[0030] By adopting the above technical scheme, in the production process, welding rods with different diameters and specifications need to be counted and discharged. At this time, the mounting block with different size limiting grooves can be replaced according to the specification of the welding rod. When replacing, first release the fixing of the fastening bolt on the mounting block, then take the mounting block off the disc, then replace the mounting block with the corresponding specification limiting groove and fix it. The welding wire can fall on the plane where the two mounting blocks and the connecting plate are located, and the conveying is realized.

[0031] Preferably, the roller comprises a pair of discs and a connecting plate, the two discs are oppositely arranged, the two ends of the connecting plate are connected to the two discs respectively, a notch is formed at the edge of the two discs, the notch is used for accommodating the welding rod, and the connecting plate is used for receiving the welding rod; a mounting block is detachably connected to the side of the disc away from the connecting plate, the limiting groove is formed in the mounting block, and the limiting groove is communicated with the notch; the connecting plate, the notch and the mounting block are spaced along the circumference of the disc.

[0034] By adopting the technical scheme, when the mounting block is disassembled and replaced, the fastening bolt needs to be rotated twice by relying on external tools, and the operation process is somewhat troublesome. In addition to fixing the mounting block by the fastening bolt, other mechanical structures can also be used for fixing.

[0035] Specifically, during installation, two thumbs of the worker pinch the two clamping blocks at the same time to compress the compression spring, the two clamping blocks enter the installation grooves of the two insertion columns, and then the insertion columns are gradually inserted into the insertion groove of the disc. When the insertion column moves to the position, the clamping block and the preset clamping groove of the disc correspond to each other at this time, and the elastic potential energy of the compression spring can control the clamping block to reset and be clamped in the clamping groove, thereby limiting the insertion column from being separated from the insertion groove, and achieving quick installation of the mounting block.

Then the other hand exerts a pulling force on the pull rope, and the direction of the pulling force is opposite to the insertion direction of the insertion column. The pulling force of the pull rope can drive the pressing rod to rotate, and the rotation of the pressing rod will generate a horizontal component force on the extension plate. Since the clamping block can only move linearly, the extension plate and the clamping block move synchronously and press the compression spring, so that the clamping block slowly enters the installation groove and is separated from the clamping groove, so as to disassemble the insertion column from the disc. The whole process does not need to borrow external tools, improving the convenience.

[0037] In a second aspect, the application also provides an electrode discharging method. The electrode is counted and discharged by using the above-mentioned discharging device with all the structures, which includes the following steps:

[0038] S1, first, the welder stores the electrode in the feeding bin. The electrode in the feeding bin is vibrated by the cam assembly and comes to the position of the roller along the traction assembly; as the roller continuously rotates, when the roller rotates to the position corresponding to the limiting groove, the electrode will fall into the limiting groove. One limiting groove can only accommodate one electrode, and each limiting groove is used to transport the electrodes one by one.

[0039] S2, as the roller continues to rotate, the limiting groove carrying the electrode gradually approaches the discharging bin, and the electrode will fall into the discharging bin under the action of its own gravity. The discharging bin is used to concentrate and store the electrodes. During the electrode discharging process, the counting sensor counts the number of electrodes in the limiting groove.

[0040] In summary, the application has the following at least one beneficial technical effect:

[0041] (1) By setting the feed bin, cam assembly, roller, traction assembly, discharge bin and counting sensor, the electrode in the feed bin is vibrated by the cam assembly, comes to the position of the roller along the traction assembly, and then falls into the limiting groove; with the continuous rotation of the roller, the electrode in the limiting groove gradually approaches the discharge bin and completes the discharge, the counting sensor counts the number of electrodes in the limiting groove, realizes the digital record of the welding material issuing information, and is convenient for subsequent tracing.

The side of the disc 61 away from the connecting plate 62 is detachably connected with a mounting block 28, the mounting block 28 is locked on the disc 61 through a fastening bolt, and a fishhook-shaped limiting groove 13 is arranged on the mounting block 28, and the limiting groove 13 is communicated with the notch 27. After the welding rod is placed on the connecting plate 62, the two ends of the welding rod are respectively located in the notch 27 of the two discs 61 and the limiting groove 13 of the mounting block 28.

[0068] In the production process, welding rods of different diameters need to be counted and discharged. At this time, the mounting block 28 with different size limiting grooves 13 can be replaced according to the size of the welding rod. When replacing, first release the fixing of the mounting block 28 by the fastening bolt, then take the mounting block 28 from the disc 61, and then replace the mounting block 28 with the corresponding size limiting groove 13 for fixing. The welding wire can fall on the plane where the two mounting blocks 28 and the connecting plate 62 are located, and the conveying is realized.

[0069] The implementation principle of the welding rod discharging device according to the embodiment of the application is as follows: when the automatic discharging device is used to automatically count the welding rods, first, the second cover plate 23 hinged to the top of the feeding bin 4 is manually opened, the welding rods to be issued are loaded into the feeding bin 4, and then the second cover plate 23 is closed. At this time, the heating plate 26 embedded in the bottom plate 10 and the second cover plate 23 is started, and cooperates with the heat preservation layer 25 arranged around the feeding bin 4 to heat and preserve the welding rods in the feeding bin 4, so as to ensure that the temperature in the feeding bin 4 is maintained in a required range, and to prepare for subsequent issuing.

[0070] When the welder needs to take the electrode, the controller triggers the release process after the authentication of the device. First, the cam assembly 5 related driving structure is started to make the cam shaft 51 rotatingly installed between the body 2 and the side plate 3 start to rotate, and the cam body 52 assembled on the cam shaft 51 rotates synchronously with the cam shaft 51. Since the outer circumferential surface of the cam body 52 and the outer circumferential surface of the roller 54 rotatably installed at the end of the push rod 53 by a pin shaft are in contact, the cam body 52 rotates to push the push rod 53 to move up and down. One end of the push rod 53 is connected to the bottom surface of the bottom plate 10, and the bottom plate 10 is rotatably installed on the connecting shaft 12 between the body 2 and the side plate 3 through the bottom connected ear 11. Therefore, the up and down movement of the push rod 53 drives the bottom plate 10 and the feed bin 4 fixed on the bottom plate 10 to vibrate up and down around the connecting shaft 12, avoiding the electrode in the feed bin 4 from being jammed, and ensuring that the electrode can move smoothly to the direction of the roller 6.

[0071] At the same time, the rotating shaft 14 rotatably installed between the body 2 and the side plate 3 and parallel to the cam shaft 51 starts to rotate, and the roller 6 assembled on the rotating shaft 14 rotates synchronously with the rotating shaft 14. The electrode in the feed bin 4 moves to the roller 6 under the vibration and enters the fishhook-shaped limiting groove 13 evenly and spaced along the length direction at the edge of the roller 6 under the action of gravity. With the continuous rotation of the roller 6, the limiting groove 13 drives the electrode to move to the discharge direction. When the electrode rotates with the limiting groove 13 to the counting sensor 9 installed on the side wall of the body 2, since the counting sensor 9 is a light receiving and emitting photoelectric sensor and its detection light path is opposite to the discharge path of the limiting groove 13 on the roller 6, the electrode will block the light of the counting sensor 9, trigger the counting signal, and realize accurate counting of each electrode.

[0072] The electrode after counting continues to rotate with the roller 6, and finally separates from the limiting groove 13 and enters the discharge bin 8 beside the roller 6. The discharge bin 8 is rotatably connected to the first bracket 17 installed on the bottom of the body 2 by a pin shaft. When a certain number of electrodes are collected in the discharge bin 8 or the welder completes the taking operation, the welder can hold the U-shaped handle 20 fixedly installed on the outer side wall of the discharge bin 8, rotate the discharge bin 8 around the pin shaft on the first bracket 17, pour out the electrodes in the discharge bin 8, and complete the whole automatic counting and releasing process of the electrodes.

[0073] Embodiment 2

[0074] The difference between this embodiment 2 and the embodiment 1 is the dismounting way of the mounting block 28. In this embodiment, the mounting block 28 is not locked by fastening bolts, but other mechanical structures. Referring to Figure 6 and Figure 7Specifically, the mounting block 28 is fixedly connected with a plug column 29, the cross section of the plug column 29 is rectangular, the plug column 29 is perpendicular to the plane where the disc 61 is located, and the disc 61 is provided with a plug slot for the plug column 29. The plug column 29 is provided with a mounting groove 30, the mounting groove 30 is provided with a clamping block 31 and a compression spring 32, the clamping block 31 is slidably connected in the mounting groove 30, and the clamping block 31 moves along the width direction of the plug column 29, that is, perpendicular to the insertion direction of the plug column 29; the clamping block 31 is used for being clamped in a clamping groove provided on the disc 61, and the clamping groove is communicated with the plug slot. The clamping block 31 can be moved in the form of a T-shaped block 33 and a T-shaped groove 34, that is, one side of the clamping block 31 is fixedly connected with the T-shaped block 33, and the T-shaped groove 34 is provided in the mounting groove 30 correspondingly, and the T-shaped block 33 moves linearly along the T-shaped groove 34. The compression spring 32 is horizontally arranged, and two ends of the compression spring 32 are connected with the plug column 29 and the clamping block 31 respectively; when the compression spring 32 is in a natural state, part of the clamping block 31 is located outside the mounting groove 30, and the other part is located in the mounting groove 30.

[0075] The clamping block 31 is fixedly connected with an extension plate 35, the extension plate 35 extends in the direction close to the mounting block 28, and the extension plate 35 moves horizontally through a driving assembly 36. The driving assembly 36 includes a pressing rod 361, a tension spring 362 and a pull rope 363, one end of the pressing rod 361 is rotatably connected to the plug column 29, the other end of the pressing rod 361 abuts at the connection position of the extension plate 35 and the clamping block 31, two ends of the tension spring 362 are hingedly connected to the plug column 29 and the pressing rod 361 respectively, one end of the pull rope 363 is connected to the pressing rod 361, and the other end of the pull rope 363 extends out of the plug column 29; wherein, the plug column 29 is provided with two plug columns 29 in parallel, the two plug columns 29 are located at two ends of the mounting block 28 respectively, and the two plug columns 29 are provided with the clamping block 31, the compression spring 32, the extension plate 35 and the driving assembly 36. It should be noted that the two ends of the two pull ropes 363 located outside the plug column 29 can be connected together, so that the two pressing rods 361 can be pulled by the staff at the same time.

[0076] During installation, the two thumbs of the staff pinch the two clamping blocks 31 at the same time so that the compression spring 32 is compressed, the two clamping blocks 31 enter the mounting grooves 30 of the two plug columns 29, and then the plug columns 29 are gradually inserted into the plug slots of the disc 61. When the plug column 29 is moved to the position, the clamping block 31 and the clamping groove position of the disc 61 correspond to each other at this time, and the elastic potential energy of the compression spring 32 can control the clamping block 31 to reset and be clamped in the clamping groove, so as to limit the plug column 29 from being separated from the plug slot, thereby realizing the rapid installation of the mounting block 28.

[0077] When disassembling, the staff can hold the mounting block 28 with one hand to better exert force on the pull rope 363. Then the other hand exerts a pulling force on the pull rope 363, and the direction of the pulling force is opposite to the insertion direction of the insertion column 29. The pulling force of the pull rope 363 can drive the pressure rod 361 to rotate, and the rotation of the pressure rod 361 generates a horizontal component force on the extension plate 35. Since the clamping block 31 can only move linearly, the extension plate 35 and the clamping block 31 move synchronously and press the compression spring 32, so that the clamping block 31 slowly enters the mounting groove 30 and is disengaged from the clamping groove, so as to disassemble the insertion column 29 from the disc 61. The whole process does not need to borrow external tools, and the convenience is improved.

[0078] Based on the above embodiment, the application also provides a welding rod discharging method. The welding rod is counted and discharged by using the above-mentioned discharging device with all the structures, which comprises the following steps:

[0079] S1: First, the operator places the welding rod specification inside the feeding bin 4. The welding rods in the feeding bin 4 are orderly arranged and conveyed to the work station of the roller 6 under the vibration of the cam assembly 5. With the uniform rotation of the roller 6, when the limiting groove 13 on the surface of the roller 6 rotates to coincide with the position of the welding rod, the welding rod will accurately fall into the limiting groove 13. Each limiting groove 13 is designed to accommodate only one welding rod. Through the circulation of multiple groups of limiting grooves 13, the welding rods are sequentially conveyed one by one.

[0080] S2: With the continuous operation of the roller 6, the limiting groove 13 carrying the welding rod will gradually move to the area close to the discharging bin 8. The welding rod falls into the discharging bin 8 under the action of its own gravity, and the discharging bin 8 bears the function of collecting and storing the welding rods. During the whole welding rod discharging process, the counting sensor 9 will count the number of welding rods conveyed by the limiting groove 13 in real time, ensuring the accurate and controllable number of welding rods.

[0081] The above are preferred embodiments of the application, but do not limit the protection scope of the application, therefore: any equivalent changes made on the structure, shape, principle of the application shall be covered within the protection scope of the application.
