Description

Technical Field

[0001] This invention relates to the field of saw blade production and processing technology, specifically to a clamping and welding device for producing jigsaw blades. Background Technology

[0002] A type of clamping and welding device for producing jigsaw blades is marketed as a saw blade welding machine. A saw blade welding machine is a device specifically designed for welding saw blades. There are two welding methods for saw blade welding machines. One of them is laser welding. The device generates a high-energy-density laser beam through a laser (such as a fiber laser or a CO2 laser). After being focused by an optical system (lens, mirrors, etc.), it forms a light spot with a very small diameter (usually 0.1-1mm) that irradiates the welded section of the saw blade. The working method of a jigsaw is different from that of other electric saws.

[0003] Jigsaws use a motor to drive the saw blade to make high-frequency reciprocating up-and-down movements (the vibration frequency is usually 50-3000 times / minute). At the same time, the user may apply lateral thrust to control the cutting trajectory. When the saw blade moves up and down, the connection between the saw tail and the motor connecting rod will bend periodically due to vibration. Long-term use can easily lead to fatigue fracture. Therefore, some high-quality jigsaw blades need to be welded with materials with certain adaptability strength during the production process.

[0004] For example, CN118720602A discloses a fixing fixture for welding saw blades. The saw blade has a mounting hole at its center. The fixture includes a placement block, a clamping block, and a holding block. When the clamping block approaches the center point, it retracts to facilitate the placement and replacement of the saw blade. When the clamping block moves away from the center point, it disperses and fixes the saw blade by contacting the mounting hole. After the clamping block contacts the mounting hole, the holding block moves towards the placement block to fix the saw blade. This fixing fixture uses a hydraulic or pneumatic system to drive the movement of the clamping block and the holding block, enabling the fixture to fix and release the saw blade in a very short time. The combined use of the clamping block and the holding block not only allows the fixture to adapt to saw blades of different sizes (simply adjusting the spacing of the clamping blocks is sufficient) but also ensures the stability of the saw blade during the welding process, avoiding welding quality problems caused by poor fixing.

[0005] 1. While existing saw blade welding machines are versatile and suitable for welding various types of saw blades, including metal cutting saw blades and woodworking saw blades, meeting the welding needs of saw blades of different materials and specifications, they have some limitations in the welding production of jigsaw blades. Because jigsaw blades are typically small, existing laser saw blade welding machines are limited by their structure and operating mode, which can only clamp and weld one blade at a time. This prevents them from fully utilizing the small size and space-saving characteristics of the saw blades for batch processing. For jigsaw blade manufacturers aiming for high-efficiency production, this single-blade welding method results in insufficient production efficiency, making it difficult to meet the needs of large-scale production, thus making the production of jigsaw blades more complicated.

[0006] 2. After the laser saw blade welding machine completes the welding process, the operator must manually open the clamps and remove the welded saw blades one by one. This process is not only tedious but also further reduces the production efficiency of the saw blades. In addition, manual removal of parts also poses certain risks. If workers do not take proper precautions when removing parts, they are very likely to suffer burns. Removing parts while the equipment is not completely stopped also poses a risk of mechanical pinching and electric shock, thus increasing the safety hazards.

[0007] To address the aforementioned issues, there is an urgent need for innovative design based on the existing clamping and welding device used in the production of jigsaw blades. Summary of the Invention

[0008] This invention addresses the problem of overly simplistic solutions in existing technologies by providing a significantly different approach. Specifically, the invention aims to provide a clamping and welding device for producing jigsaw blades. This addresses the issue that laser saw blade welding machines, as described in the background, are limited by their structure and operating mode, which can only clamp and weld one saw blade at a time. This prevents the full utilization of the small size and minimal space required for batch processing. Furthermore, manual opening of the clamps and removal of the welded saw blades one by one further reduces efficiency and increases safety hazards.

[0009] To achieve the above objectives, the present invention provides the following technical solution: a clamping and welding device for producing jigsaw blades, including a conveyor belt, a saw blade welding mechanism arranged in a row on the outer wall of the conveyor belt for bringing the welding points of the saw blade and the saw tail close together during saw blade welding, and a saw blade unloading mechanism disposed on one side of the saw blade welding mechanism for clamping and unloading the saw blade and the saw tail.

[0010] The saw blade welding mechanism includes sluices arranged at equal intervals on the outer wall of the conveyor belt. A slider is movably installed on the inner wall of the sluice, one end of the slider is connected to a top block, and a limit block is installed on one side of the outer wall of the sluice.

[0011] The saw blade feeding mechanism includes a connecting block installed on one side of the outer wall of the slider. One end of the connecting block is connected to a placement groove. A second telescopic rod is installed on one side of the inner wall of the placement groove. One end of the second telescopic rod is connected to a movable clamping plate. A movable block is provided on one side of the outer wall of the movable clamping plate.

[0012] Preferably, a connecting plate is connected to the top of the outer wall of the slider, a telescopic rod is connected to the outer wall of the connecting plate, and a spring is installed around the outer wall of the telescopic rod.

[0013] Preferably, a fixing clamping plate is installed on the other side of the inner wall of the placement groove, and a second spring is installed around the outer wall of the second telescopic rod.

[0014] Preferably, a limiting plate is installed on one side of the outer wall of the conveyor belt, a laser welder is movably installed on one side of the conveyor belt, a receiving bin is provided at the bottom of the laser welder, and a discharging bin is provided on one side of the limiting plate.

[0015] Preferably, cavities are provided on one side and at the top of the outer wall of the slide groove, the connecting block passes through the cavity on one side of the outer wall of the slide groove and connects to one side of the outer wall of the slider, and the connecting plate passes through the cavity at the top of the outer wall of the slide groove and connects to the top of the outer wall of the slider.

[0016] Preferably, the top block extends through one end of the slide groove and is connected to one end of the slider, and the outer wall of the top block is inclined.

[0017] Preferably, the three-dimensional view of the limiting plate is semi-circular, and both ends of the limiting plate are inclined, with the inclination angles of the two ends of the limiting plate being the same as the inclination angle of the outer wall of the top block.

[0018] Preferably, a cavity is provided on one side of the outer wall of the connecting block, and the movable block passes through the cavity of the connecting block.

[0019] Preferably, one end of the movable block is semi-circular, and one end of the limiting block is inclined.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] 1. This invention achieves batch clamping and welding of jigsaw blades through a conveyor belt, a saw blade welding mechanism, and a saw blade unloading mechanism, thereby improving the production efficiency of jigsaw blades. While existing saw blade welding machines can meet various saw blade welding needs, in jigsaw blade production, they can only clamp and weld one saw blade at a time, making it impossible to utilize the small size of jigsaw blades for batch processing, resulting in low production efficiency and difficulty in meeting large-scale production demands. This invention, however, uses multiple saw blade welding mechanisms arranged in a row on a conveyor belt to simultaneously clamp and weld multiple sets of saw blades and saw tails. During conveyor belt operation, the top block, slider, and limiting structure work together to automatically bring the saw blades and saw tails together for welding. Compared to traditional equipment, this significantly improves welding efficiency and effectively solves the problem of insufficient jigsaw blade production efficiency.

[0022] 2. This invention reduces the efficiency loss and safety hazards caused by manual part handling through the saw blade unloading mechanism. Traditional laser saw blade welding machines require manual part removal after welding, which is not only cumbersome and reduces production efficiency, but also poses safety risks such as burns, mechanical injuries, and electric shock. In contrast, this invention moves the placement trough along a conveyor belt after welding. Through the cooperation of limit blocks, movable blocks, and spring structures, the movable clamping plate is automatically released. When the placement trough moves to the end of the conveyor belt, the saw blade can fall into the receiving bin by gravity, eliminating the need for manual contact with the welded saw blade. This avoids efficiency fluctuations caused by manual part handling and eliminates the safety hazards associated with manual operation, thus ensuring a safe and efficient production process.

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] Please see Figures 1 to 12 The present invention provides a technical solution: a clamping and welding device for producing jigsaw blades, including a conveyor belt 1, a saw blade welding mechanism 2 arranged on the outer wall of the conveyor belt 1 for bringing the welding points of the saw blade and the saw tail close together during saw blade welding, and a saw blade unloading mechanism 3 disposed on one side of the saw blade welding mechanism 2 for clamping and unloading the saw blade and the saw tail.

[0038] The saw blade welding mechanism 2 includes a sluice 201 arranged at equal intervals on the outer wall of the conveyor belt 1. A slider 202 is movably installed on the inner wall of the sluice 201. One end of the slider 202 is connected to a top block 206. A limit block 207 is installed on one side of the outer wall of the sluice 201.

[0039] The saw blade feeding mechanism 3 includes a connecting block 301 installed on one side of the outer wall of the slider 202. One end of the connecting block 301 is connected to a placement groove 302. A second telescopic rod 304 is installed on one side of the inner wall of the placement groove 302. One end of the second telescopic rod 304 is connected to a movable clamping plate 306. A movable block 307 is provided on one side of the outer wall of the movable clamping plate 306.

[0040] In this embodiment, when the top block 206 moves, it causes the slider 202 to slide to one side on the inner wall of the slide groove 201. When the slider 202 slides, it causes the connecting block 301 on one side of its outer wall to move. When the connecting block 301 moves, it causes the placement groove 302 to move. When the placement groove 302 moves, one end of the movable block 307 slides along the outer wall of the limiting block 207. Since one end of the movable block 307 is inclined, the movable block 307 is no longer limited by the limiting block 207. Furthermore, since the second spring 305 is in a stretched state when one end of the movable block 307 is pressed against the outer wall of the limiting block 207, the second spring 305 will contract when the movable block 307 is no longer limited by the limiting block 207, causing the movable clamping plate 306 to move to one side. When the saw blade is placed, the movable clamping plate 306 and the fixed clamping plate 303 will have space to place the saw blade. After the saw blade is placed, the sliding block 202 will stretch the first telescopic rod 204 and the first spring 205 when it moves. At this time, the first telescopic rod 204 and the first spring 205 will drive the sliding block 202 to reset through the connecting plate 203, thereby resetting the movable clamping plate 306. This allows the movable clamping plate 306 and the fixed clamping plate 303 to clamp the saw blade (by using the cooperation of the top block 206 and the limiting plate 4 to drive the placement groove 302 to move, the saw blade and the saw tail in the placement groove 302 can come closer to each other during welding, making the welding of the saw blade and the saw tail more secure and preventing the occurrence of false welding).

[0041] A connecting plate 203 is connected to the top of the outer wall of the slider 202. A telescopic rod 204 is connected to the outer wall of the connecting plate 203. A spring 205 is installed around the outer wall of the telescopic rod 204.

[0042] In this embodiment, when the slider 202 moves, it will cause the first telescopic rod 204 and the first spring 205 to be stretched. At this time, the first telescopic rod 204 and the first spring 205 will drive the slider 202 to reset through the connecting plate 203, thereby causing the movable clamping plate 306 to reset, so that the movable clamping plate 306 and the fixed clamping plate 303 clamp the saw blade (when placing the saw blade and saw tail, the actual steps are simply to press the top block 206 and press it to one side to place the saw blade into the inner wall of the placement groove 302, thereby completing the placement of the saw blade and saw tail, and the subsequent welding and unloading will be automatically completed through the cooperation of the conveyor belt 1, the saw blade welding mechanism 2 and the saw blade unloading mechanism 3).

[0043] A fixing clamping plate 303 is installed on the other side of the inner wall of the placement groove 302, and a second spring 305 is installed around the outer wall of the second telescopic rod 304.

[0044] In this embodiment, after the placement slot 302 moves to a certain position, since one end of the movable block 307 is inclined, the movable block 307 is no longer limited by the limiting block 207. Furthermore, since the second spring 305 is in a stretched state when one end of the movable block 307 is pressed against the outer wall of the limiting block 207, the second spring 305 will contract when the movable block 307 is no longer limited by the limiting block 207, causing the movable clamping plate 306 to move to one side. At this time, a space for placing the saw blade is created between the movable clamping plate 306 and the fixed clamping plate 303 (when the top block 206 is in its initial position). When the movable block 307 is in close contact with the outer wall of the limiting block 207, the other end of the movable block 307, which is the end that moves with the movable clamping plate 306, will cause the movable clamping plate 306 to be in close contact with the fixed clamping plate 303. At this time, the second spring 305 is in a stretched state. When the movable block 307 moves to the inclined end of the limiting block 207, since there is no longer a limiting force from the outer wall of the limiting block 207, the second spring 305 will contract, thereby causing the movable clamping plate 306 to move to one side, thus providing space for placing the saw blade.

[0045] A limit plate 4 is installed on one side of the outer wall of the conveyor belt 1, a laser welder 5 is movably installed on one side of the conveyor belt 1, a receiving bin 6 is provided at the bottom of the laser welder 5, and a discharging bin 7 is provided on one side of the limit plate 4.

[0046] In this embodiment, as the conveyor belt 1 operates, the top block 206 is kept in one position by the conveyor belt 1, so that the movable clamping plate 306 is always in a loose state. When the placement groove 302 moves to one end of the conveyor belt 1, the placement groove 302 will flip because one end of the conveyor belt 1 is semi-circular. Since the saw blade inside the placement groove 302 is no longer clamped and limited by the movable clamping plate 306, it will fall into the receiving bin 6 due to gravity as the placement groove 302 flips. (The integrated process of welding the saw blade and the saw tail is completed by the cooperation of the saw blade welding mechanism 2 and the saw blade unloading mechanism 3 driven by the transmission power of the conveyor belt 1, thereby improving the production efficiency of the jigsaw saw blade.)

[0047] The outer wall of the slide 201 has cavities on one side and at the top. The connecting block 301 passes through the cavity on one side of the outer wall of the slide 201 and is connected to one side of the outer wall of the slider 202. The connecting plate 203 passes through the cavity at the top of the outer wall of the slide 201 and is connected to the top of the outer wall of the slider 202.

[0048] In this embodiment, when the top block 206 moves, it will cause the slider 202 to slide to one side on the inner wall of the slide groove 201. When the slider 202 slides, it will cause the connecting block 301 on one side of its outer wall to move. When the connecting block 301 moves, it will cause the placement groove 302 to move. When the placement groove 302 moves, one end of the movable block 307 will slide along the outer wall of the limiting block 207. After the placement groove 302 moves to a certain position, since one end of the movable block 307 is inclined, the movable block 307 is no longer limited by the limiting block 207. And since the second spring 305 is in a stretched state when one end of the movable block 307 is close to the outer wall of the limiting block 207, when the movable block 307 is no longer limited by the limiting block 207, the second spring 305 will contract, causing the movable clamping plate 306 to move to one side.

[0049] The top block 206 passes through one end of the slide groove 201 and is connected to one end of the slider 202. The outer wall of the top block 206 is inclined.

[0050] In this embodiment, the top block 206 can be limited by the limiting plate 4 and kept in one position, so that the movable clamping plate 306 is always in a loose state. When the placement groove 302 moves to one end of the conveyor belt 1, the placement groove 302 will flip because one end of the conveyor belt 1 is semi-circular. Since the saw blade inside the placement groove 302 is no longer clamped and limited by the movable clamping plate 306, it will fall into the receiving bin 6 due to gravity as the placement groove 302 flips.

[0051] The three-dimensional view of the limiting plate 4 is semi-circular, and both ends of the limiting plate 4 are inclined. The inclination angle of the two ends of the limiting plate 4 is the same as the inclination angle of the outer wall of the top block 206.

[0052] In this embodiment, as one end of the top block 206 moves to the outer wall of the limiting plate 4, the connecting block 301 will drive the placement groove 302 to move to a certain position as the slider 202 moves. At this time, the movable block 307 set on the outer wall of the movable clamping plate 306 will move to the inclined position of one end of the limiting block 207. At this time, the second telescopic rod 304 and the second spring 305 will drive the movable clamping plate 306 to reset, so that the movable clamping plate 306 releases the clamped saw blade. As the conveyor belt 1 runs, the top block 206 will be limited by the limiting plate 4 and always kept in one position.

[0053] A cavity is provided on one side of the outer wall of the connecting block 301, and the movable block 307 passes through the cavity of the connecting block 301.

[0054] In this embodiment, the movable block 307 is no longer limited by the limiting block 207, and since the second spring 305 is in a stretched state when one end of the movable block 307 is pressed against the outer wall of the limiting block 207, the second spring 305 will contract when the movable block 307 is no longer limited by the limiting block 207, causing the movable clamping plate 306 to move to one side.

[0055] One end of the movable block 307 is semi-circular, and one end of the limiting block 207 is inclined.

[0056] In this embodiment, the movable block 307 on the outer wall of the movable clamping plate 306 will move to the position where one end of the limiting block 207 is tilted. At this time, the second telescopic rod 304 and the second spring 305 will drive the movable clamping plate 306 to reset.

[0057] Working Principle: When using this jigsaw blade production clamping and welding device, the operator first needs to stand on both sides of the conveyor belt 1. Then, the saw blade and saw tail are taken out from the feeding bin 7. Afterward, the operator needs to press the top block 206 and move it to one side. When the top block 206 moves, it will drive the slider 202 to slide to one side on the inner wall of the groove 201. When the slider 202 slides, it will drive the connecting block 301 on one side of its outer wall to move. When the connecting block 301 moves, it will drive the placement groove 302 to move. When the placement groove 302 moves, one end of the movable block 307 will slide along the outer wall of the limiting block 207. After the placement groove 302 moves to a certain position, since one end of the movable block 307 is tilted, the movable block 307 no longer has the limiting block 207. The limit of 07, and since the second spring 305 is in a stretched state when one end of the movable block 307 is pressed against the outer wall of the limit block 207, when the movable block 307 is no longer limited by the limit block 207, the second spring 305 will contract, causing the movable clamping plate 306 to move to one side. At this time, there is space between the movable clamping plate 306 and the fixed clamping plate 303 to place the saw blade. After the saw blade is placed, when the slider 202 moves, it will drive the first telescopic rod 204 and the first spring 205 to be stretched. At this time, the first telescopic rod 204 and the first spring 205 will drive the slider 202 to reset through the connecting plate 203, thereby causing the movable clamping plate 306 to reset, so that the movable clamping plate 306 and the fixed clamping plate 303 clamp the saw blade.

[0058] Secondly, since both the saw blade welding mechanism 2 and the saw blade unloading mechanism 3 are installed on the outer wall of the conveyor belt 1, the operation of the conveyor belt 1 will drive the saw blade welding mechanism 2 and the saw blade unloading mechanism 3 to move. When the chute 201 moves with the conveyor belt 1, the top block 206 will gradually touch the inclined surface of one end of the limiting plate 4. At this time, one end of the limiting plate 4 will stick to the outer wall of the top block 206 and squeeze the top block 206 to move. When the top block 206 moves, it will gradually drive the slider 202 to slide on the inner wall of the chute 201. The setting position of the limiting plate 4 is exactly slightly forward of the laser welding point of the laser welder 5. This makes the top block 206 move in a certain direction. When the distance is short, the slider 202 will cause the placement groove 302 to move to one side, and the saw blade and saw tail clamped on the inner wall of the placement groove 302 will move closer to each other until they are pressed together. After the saw blade and saw tail are pressed together, the top block 206 does not move completely to the outer wall of the limiting plate 4, but is still a little distance away from the outer wall of the limiting plate 4. Then the laser of the laser welder 5 will weld the saw blade and saw tail. During the welding, a certain amount of extrusion force is required to make the saw blade and saw tail slowly move closer together while welding. At this time, as the top block 206 moves, the saw blade and saw tail will slowly move closer to each other. After the saw blade welding is completed, one end of the top block 206 will move to the outer wall of the limiting plate 4.

[0059] Finally, as one end of the top block 206 moves to the outer wall of the limiting plate 4, the connecting block 301 moves the placement groove 302 to a certain position as the slider 202 moves. At this time, the movable block 307 on the outer wall of the movable clamping plate 306 moves to the inclined position of one end of the limiting block 207. At this time, the second telescopic rod 304 and the second spring 305 drive the movable clamping plate 306 to reset, causing the movable clamping plate 306 to release the clamped saw blade. And as the conveyor belt 1 rotates, The top block 206 is kept in one position by the limiting plate 4, so that the movable clamping plate 306 is always in a loose state. When the placement groove 302 moves to one end of the conveyor belt 1, the placement groove 302 will flip because one end of the conveyor belt 1 is semi-circular. Since the saw blade inside the placement groove 302 is no longer clamped and limited by the movable clamping plate 306, it will fall into the receiving bin 6 due to gravity as the placement groove 302 flips. At this point, the work of the invention is completed.

[0060] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
