Abstract
Description
Technical Field
[0001] This utility model relates to the field of welding equipment technology, and in particular to a welding wire allowance detection device and a welding machine. Background Technology
[0002] Existing welding machines have an internal wire reel assembly on which the welding wire is wound. During welding, the wire reel assembly rotates to continuously supply welding wire to the user. However, because the inside of the welding machine is enclosed by a housing, after a period of use, the user needs to check the remaining welding wire on the wire reel assembly to ensure that welding work can continue. If the welding wire is exhausted and the user does not notice, the welding machine will continue to work, which will affect the lifespan of the welding machine. In the past, the user could only open the welding machine housing to check the remaining welding wire. However, the welding machine housing is usually tightly installed, and the user's steps to open the housing are cumbersome. After checking the remaining welding wire, the user also needs to reinstall the housing before the welding machine can be put into subsequent welding work, which is inconvenient to use.

[0031] like Figures 1 to 5 As shown, a welding wire balance detection device according to a first aspect embodiment of the present invention includes a substrate 100, a weighing sensor 200, a support assembly 300, a wire winding spool assembly 400, and a processing module 700. The weighing sensor 200 is disposed on the substrate 100 and is used to detect the weight information of an object. The support assembly 300 has a receiving portion and is mounted on the weighing sensor 200 through the receiving portion. The wire winding spool assembly 400 is used to be wound with welding wire and is rotatably disposed on the support assembly 300. The processing module 700 is disposed on the substrate 100 and is connected to the weighing sensor 200 to output the welding wire balance according to the weight information.
[0032] Among them, the wire balance detection device can be applied to the welding machine, the substrate 100 can be the bottom sheet metal part of the welding machine housing, and the weighing sensor 200 can be selected from conventional pressure strain gauges. The object applies pressure to the pressure strain gauge, causing the pressure strain gauge to deform, thereby calculating the weight of the object.
[0033] The processing module 700 can be selected from MCU or CPU and its auxiliary circuits. The processing module 700 is connected to the weighing sensor 200. The processing module 700 acquires and processes the electrical signal detected by the weighing sensor 200. The weighing sensor 200 detects the weight of the support assembly 300, the wire winding spool assembly 400 and the welding wire. Since the weights of the support assembly 300 and the wire winding spool assembly 400 are known, the weight of the welding wire can be determined. As the welding wire is used, the weight gradually decreases. The processing module 700 can determine the remaining amount of welding wire based on the weight information.
[0034] This design is convenient and reliable, allowing users to know the remaining welding wire in a timely manner and ensuring the service life of the welding machine.
[0035] In some embodiments of this utility model, such as Figure 3 As shown, the support assembly 300 includes a stand 310, the stand 310 is provided with a crossbar 320 extending from the side of the stand 310 to define the receiving part, the stand 310 is also provided with a pivot, and the winding spool assembly 400 is rotatably connected to the support assembly 300 through the pivot.
[0036] The wire winding spool assembly 400 has a certain volume. The upright frame 310 is placed vertically to protrude from the base plate 100. The cross frame 320 is attached to the load cell 200. The weight of the support assembly 300, the wire winding spool assembly 400 and the welding wire is applied to the load cell 200 through the cross frame 320.

[0037] In some embodiments of this utility model, such as Figure 1 , 2 As shown, the wire balance detection device also includes a wire winding cover 500, which is disposed on the support frame 310. The wire winding cover 500 has a cavity inside and a wire outlet communicating with the cavity.

[0038] The wire winding cover 500 forms a cavity to protect the wire winding spool assembly 400 and the welding wire wound on the wire winding spool assembly 400. The welding wire is output from the wire outlet. The rotating shaft is inserted through the wire winding cover 500, and the wire winding spool assembly 400 rotates in the cavity.
[0039] The wire winding cover 500 may be provided with an opening communicating with the cavity, and the wire winding cover 500 may also be movably provided with a cover that can close or open the opening, so as to facilitate the user to replenish the welding wire.
[0040] In some embodiments of this utility model, such as Figure 4As shown, the wire winding spool assembly 400 includes a take-up roller 410, a first limiting member 420, and a second limiting member 430. The take-up roller 410 is coaxially connected to the rotating shaft. The welding wire is wound around the take-up roller 410. The first limiting member 420 is disposed at the end of the take-up roller 410 away from the upright frame 310, and the second limiting member 430 is disposed at the end of the take-up roller 410 close to the upright frame 310. Both the first limiting member 420 and the second limiting member 430 form limiting end walls to prevent the wound welding wire from coming off at the end of the take-up roller 410.
[0041] The first limiting member 420 and the second limiting member 430 can both be ribs or rings that protrude radially toward the take-up roller 410, thereby preventing the coiled welding wire from coming off at the end of the take-up roller 410.
[0042] In some embodiments of this utility model, such as Figure 4 As shown, the first limiting member 420 is detachably connected to the take-up roller 410.
[0043] Since the first limiting member 420 is away from the bracket assembly 300, after the first limiting member 420 is removed, the user can easily install the coiled welding wire into the take-up roller 410 to quickly replenish the welding wire, and then install the first limiting member 420 onto the take-up roller 410.
[0044] In some embodiments of this utility model, the first limiting member 420 is connected to the take-up roller 410 by a threaded structure, and the first limiting member 420 is provided with a driven rib 421, and the driven rib 421 is provided with a friction-increasing part 422 around the rotation direction.
[0045] The friction-enhancing part 422 can be a corrugated uneven wall surface arranged around the rotation direction, or the friction-enhancing part 422 can be a micro-protrusion texture layer. The first limiting member 420 can be disc-shaped. The first limiting member 420 has a collar on its side facing the take-up roller 410. The thread structure can include an external thread provided on the outer peripheral wall of the take-up roller 410 and an internal thread provided on the inner peripheral wall of the collar. The collar is sleeved on the end of the take-up roller 410 and the external thread and the internal thread are detachably connected. The user can apply force to the friction-enhancing part 422 to unscrew the first limiting member 420.
[0046] In some embodiments of this utility model, a vertically placed isolation plate 600 is provided on the substrate 100, the isolation plate 600 has an installation opening 610, the upright frame 310 passes through the installation opening 610, the wire winding spool assembly 400 is located on one side of the isolation plate 600, and the weighing sensor 200 is located on the other side of the isolation plate 600.
[0047] The isolation plate 600 can separate the wire winding spool assembly 400 and the load cell 200. The wire winding spool assembly 400 will rotate during the wire feeding process. The isolation plate 600 can reduce the risk that the wire winding spool assembly 400 may drive other objects to touch the load cell 200 during the rotation, thus ensuring the accuracy of the load cell 200 detection.
[0048] Specifically, the isolation plate 600 is provided with a wire feeding port 620, which is directly opposite the wire outlet of the wire winding cover 500 to facilitate the feeding of welding wire.

After the processing module 700 processes and obtains the remaining amount of welding wire, it can use the display module 800 to output and display the result.
[0052] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0053] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
