Description

Technical Field

[0001] The utility model relates to the technical field of spot welding equipment, in particular to a spectacle buckle spot welding line equipment. Background Technique

[0002] In the spectacle manufacturing industry, the processing and assembly of spectacle buckles are crucial links. In the traditional processing of spectacle buckles, tin cutting and spot welding operations are usually completed manually or semi-automatically, which not only leads to low production efficiency, but also makes it difficult to guarantee the accuracy and consistency of manual operations, thus affecting the overall quality and assembly effect of spectacle buckles. In the manufacturing process of spectacle buckles, tin cutting requires precise control of the cutting depth and position to ensure good contact between the tin sheet and the spectacle buckle. However, traditional manual or semi-automatic tin cutting equipment often fails to achieve such precise control, resulting in uneven cutting quality, which in turn affects subsequent spot welding operations. Spot welding operations require highly precise control. During the assembly process of spectacle buckles, spot welding is used to firmly connect the tin sheet to the spectacle buckle. Traditional manual or semi-automatic spot welding equipment usually has problems such as cumbersome operation, low efficiency, and unstable welding quality. In addition, manual operation is also easily affected by human factors, resulting in inconsistent welding quality. At present, the fully automatic tin cutting, tin feeding and spot welding equipment on the market still has some deficiencies in terms of function, performance and operation convenience. For example, the degree of automation is not high and the precise control ability is insufficient. Summary of the Invention

Embodiment

[0029] As Figure 1-8 shown, the present utility model provides an equipment for spot welding wire of spectacle buckles, which includes a bottom plate 1 for supporting the internal structure of the equipment and a housing 5 for wrapping the internal structure of the equipment, and further includes:

[0030] A tin cutting and feeding mechanism 2, which extracts tin wire from a coiled tin wire roll and cuts it into segments for the next process operation; an automatic spot welding mechanism 3, which sucks up the tin segments and places them on the workpiece to be processed, and after spot welding, they fall into the collection module; a feeding mechanism 4, which includes a screening plate 404 and a second feeding groove 402, and the screening plate 404 screens out the correctly placed spectacle buckles and transports them to the automatic spot welding mechanism 3 through the second feeding groove 402.

[0031] Among them, the tin cutting and feeding mechanism 2 is responsible for extracting tin wire from the coiled tin wire roll and cutting it into segments as needed, providing raw materials for the subsequent spot welding process; through an automated method, rapid extraction and accurate cutting of the tin wire are achieved.

[0032] The automatic spot welding mechanism 3 can automatically suck up the cut tin segments and accurately place them on the spectacle buckles to be processed, and then perform spot welding operations; after spot welding, the welded spectacle buckles will fall into the collection module, waiting for further processing or inspection. It has a high degree of automation and precise operation, which can greatly improve production efficiency and welding quality.

[0033] The feeding mechanism 4 includes a screening plate 404 and a second feeding groove 402. The screening plate 404 is used to screen the spectacle buckles to ensure that they enter the second feeding groove 402 in a correctly placed posture, and the second feeding groove 402 transports these spectacle buckles to the automatic spot welding mechanism 3 for welding; through two steps of screening and feeding, the correct posture and accurate position of the spectacle buckles are ensured, providing a guarantee for the subsequent welding operation.

[0034] See Figure 4 and Figure 5, the automatic spot welding mechanism 3 is provided with a first frame body 201. A first air cylinder 202 is horizontally arranged at the top of the first frame body 201. The movable end of the first air cylinder 202 is connected with a vertically arranged second air cylinder 203. The movable end of the second air cylinder 203 is fixedly connected with a spot welding pen 204. A horizontally arranged third air cylinder 205 and a first feeding groove 206 for conveying workpieces to be processed are arranged in the middle of the first frame body 201. A spot welding table 207 is arranged at the end of the first feeding groove 206. The movable end of the third air cylinder 205 pushes the workpiece to be processed in the first feeding groove 206 to the spot welding table 207.

[0035] The first air cylinder 202 is responsible for the movement in the horizontal direction to position the spot welding pen 204 above the workpiece to be processed; while the second air cylinder 203 is responsible for the movement in the vertical direction to ensure the precise contact between the spot welding pen 204 and the workpiece to be processed.

[0036] The third air cylinder 205 is responsible for pushing the workpiece to be processed in the horizontal direction to move it from the first feeding groove 206 to the spot welding table 207. After the workpiece to be processed is pushed to the spot welding table 207, the spot welding pen 204 performs the welding operation here.

[0037] From the workpiece to be processed being conveyed through the first feeding groove 206 to the spot welding table 207, to the first air cylinder 202 and the second air cylinder 203 working together to position the spot welding pen 204 on the workpiece to be processed, and then to the completion of the welding operation, the whole process realizes a high degree of automation and precise control.

[0038] See Figure 4 and Figure 5 , a slide 209 is arranged on the side of the spot welding table 207. A fourth air cylinder 208 is installed on the opposite side of the slide 209. A collection box 210 is placed at the outlet of the slide 209. The fourth air cylinder 208 pushes the processed workpiece at the spot welding table 207 to slide into the slide 209 and fall into the collection box 210.

[0039] It provides a smooth sliding channel for quickly and stably transferring the processed workpiece after the spot welding operation from the spot welding table 207 to the collection area, improving the automation degree and efficiency of the whole production line.

[0040] The fourth air cylinder 208 is installed on the opposite side of the slide 209 and is responsible for pushing the processed workpiece at the spot welding table 207. After the processed workpiece completes the spot welding operation, the fourth air cylinder 208 pushes the processed workpiece from the spot welding table 207 to the entrance of the slide 209.

[0041] The collection box 210 is placed at the outlet of the slide 209 and is used to collect the processed workpieces that slide down through the slide 209. The design of the collection box 210 facilitates the staff to take away the processed workpieces that have completed spot welding at any time for subsequent processing or inspection. At the same time, the collection box 210 also plays a role in tidying up the work site and keeping the working environment clean.

[0042] See Figure 4 and Figure 5 The slide 209 is provided with a movable baffle 212, and the upper side of the movable baffle 212 is movably connected to the outlet of the slide 209.

[0043] The design of the movable baffle 212 can ensure that the spectacle buckle accurately pushes open the baffle and enters the collection box 210 when sliding down. The design avoids the possible deviation or scattering of the spectacle buckle during the sliding process.

[0044] See Figure 4 and Figure 5 The first frame 201 is provided with a fifth cylinder 213, and a transport table 211 for transporting the cut tin segments is arranged at the movable end of the fifth cylinder 213.

[0045] In the spectacle buckle spot welding line equipment, the fifth cylinder 213 arranged on the first frame 201 and the transport table 211 at its movable end jointly transport the cut tin segments.

[0046] The fifth cylinder 213 drives the transport table 211 to move horizontally through its telescopic movement, and accurately transports the cut tin segments from the initial position to the working area of the automatic spot welding mechanism 3 after being cut by the tin cutting and feeding mechanism 2.

[0047] See Figure 6 and Figure 7 The tin cutting and feeding mechanism 2 is provided with a second frame 301. A support bar 302 is arranged on the second frame 301. A reel 303 for installing a tin wire coil is arranged on one side of the support bar 302. A wire extractor 305 is also arranged above the second frame 301. The end of the tin wire coil in the reel 303 is installed in the wire extractor 305 and extracted for use; a sixth cylinder 306 is arranged above the second frame 301, and a tin cutting head 307 is connected to the movable end of the sixth cylinder 306. The tin wire extracted by the wire extractor 305 extends out and is cut into segments by the tin cutting head 307.

[0048] The second frame 301 provides the basic structure of the tin cutting and feeding mechanism 2 for installing and supporting other components. The support bar 302 is fixed on the second frame 301, and a reel 303 for installing a tin wire coil is arranged on one side of it. The tin wire coil is installed on the reel 303 to provide a tin wire source for the entire tin feeding process.

[0049] Through the operation of the wire extractor 305, the tin wire can be extracted from the tin wire coil. When the wire extractor 305 extracts the tin wire to a predetermined length, the sixth cylinder 306 is activated to push the tin cutting head 307 to move downward to cut the tin wire into segments for subsequent welding operations.

[0050] See Figure 6 and Figure 7, one side of the wire extractor 305 is connected to an adjusting rotating shaft 310. The second frame body 301 is also provided with a motor 308. A belt 309 is connected between the rotor of the motor 308 and the adjusting rotating shaft 310. When the motor 308 rotates, it drives the adjusting rotating shaft 310 to rotate and extract the solder wire.

[0051] When the system needs solder wire, the motor 308 starts to rotate. The coil inside the motor 308 generates a rotational force under the action of the magnetic field, and this rotational force is transmitted to the belt 309 through the shaft of the motor 308.

[0052] As a transmission device, the belt 309 transmits the rotational force of the motor 308 to the adjusting rotating shaft 310. The connection between the belt 309 and the adjusting rotating shaft 310 ensures smooth and accurate transmission.

[0053] Driven by the belt 309, the adjusting rotating shaft 310 rotates to drive the wire extractor 305 to work, extracting the solder wire from the solder wire reel and providing the required solder wire for subsequent welding operations.

[0054] See Figure 6 and Figure 7 , a locking member 304 is installed on one side of the reel 303.

[0055] Through its fastening effect, the locking member 304 firmly fixes the solder wire reel on the reel 303, ensuring that the solder wire reel will not shift or loosen due to the pulling force during the wire extraction process.

[0056] In an industrial production environment, vibrations and oscillations of machines are common. The locking member 304 can effectively resist these external vibrations and maintain the stable state of the solder wire reel.

[0057] In the case of high-speed wire extraction or long-term use, the solder wire reel may gradually loosen or even fall off due to inertia or gravity. The presence of the locking member 304 greatly reduces this risk and ensures the firmness of the solder wire reel.

[0058] Through the locking effect of the locking member 304, the connection between the solder wire reel and the reel 303 becomes tighter, thereby reducing the possibility of falling off.

[0059] See Figure 2 , an operation panel 51 is provided on the housing 5.

[0060] Users can directly operate and control the mechanical equipment through the controls such as buttons, switches, knobs or touch screens on the panel. The various controls on the panel have clear markings and instructions, facilitating users to quickly understand and use.

[0061] The operation panel 51 allows users to set and adjust various parameters of the mechanical equipment according to actual needs, such as welding current, solder feeding speed, cutting length, etc. The operation panel 51 is equipped with indicator lights for displaying the current status, working information, etc. of the mechanical equipment.
