Description

Technical Field

[0001] The invention relates to the technical field of label installation and fixing, and in particular to a label rapid welding device. Background Art

[0002] Labels are auxiliary devices that provide product information. For example, clothing needs to be labeled to indicate size, raw material ratio, washing method and other information. Metal parts can be labeled to provide product size, steel type and other information. High-pressure containers need to be labeled to provide capacity, container pressure resistance and storage conditions and other information. For clothing, a sewing machine can be used to sew fabric labels on collars and corners. However, for metal parts, high-pressure containers and other devices with metal outer surfaces, in order to ensure that the label is not damaged and not easy to fall off, a metal nameplate is usually used as a label, and then the metal sheet label is installed on the outside of the device.

[0003] At present, the installation methods of metal sheet labels usually include riveting, clamping, screw connection, welding, etc. Since welding is the most efficient in operation, ordinary welding is also convenient for removing the label, not easy to damage the label, and easy to reuse. Therefore, for products whose installation objects are weldable metal materials, welding is usually used to install the label.

[0004] For products such as small plates and containers that are easy to fix and place, the welding work can be completed by using a traditional automatic welding machine. The product is placed on the conveying mechanism of the automatic welding machine, and it passes through the label placement device and the welding gun in turn to complete the automatic label placement and welding work. However, for can-shaped metal containers, because their sides are arc surfaces, when labels need to be welded on their sides, traditional automatic welding machines are difficult to complete the work of fixing, automatically placing labels, and welding. The use of manual operation for label welding undoubtedly greatly increases the workload, and the processing efficiency is also very low, which is not conducive to large-scale production in factories. Therefore, a better label rapid welding device is needed to specifically solve the problem of side label welding of cylindrical can-shaped containers. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention provides a label rapid welding device, which solves the problems in the prior art that automatic welding machines cannot weld can-shaped containers, and manual welding has low efficiency and large workload.

[0006] According to an embodiment of the present invention, a label rapid welding device includes a workbench and a placement rack, a feeding assembly, a transfer assembly, a limit assembly and a welding assembly respectively arranged on the workbench.

[0007] The feeding component is arranged on the upper surface of the workbench, and the feeding component automatically and continuously outputs a single label to the position where the transfer component is located;

[0008] The transfer component is arranged corresponding to the feeding component, and transports the label output by the feeding component to the position where the placement rack is located;

[0009] The limiting component is arranged in cooperation with the placement rack. The limiting component fixes and limits or releases the limit of the label placed on the placement rack, and does not affect the work of the welding component at the same time;

[0010] The welding component is arranged opposite to the limiting component. When the limiting component fixes and limits the label, the welding component abuts against the label for welding processing. When the limiting component releases the limit, the welding component moves away from the label.

[0011] Further, the placement rack is arranged at one side edge of the workbench. The placement rack is a horizontally arranged cylindrical structure or a flat plate structure. The feeding component and the transfer component are arranged on the side of the workbench far from the placement rack, and the limiting component and the welding component are arranged on the side of the workbench close to the placement rack, and the limiting component and the welding component are respectively arranged on opposite sides of the placement rack.

[0012] Further, the feeding component includes a vertically arranged feeding groove and a pusher arranged on the side far from the transfer component opposite to the feeding groove. The feeding groove is a vertically arranged hollow cylindrical structure, and the internal cross-sectional shape corresponds to the shape of the label, so that the label is restricted in the feeding groove and can only move vertically. Horizontally strip-shaped openings are respectively arranged at the bottom of the feeding groove corresponding to the opposite sides of the transfer component and the pusher, and the openings on both sides are arranged opposite to each other. The size of the openings is just enough for the label to pass through horizontally;

[0013] The pusher includes a horizontally arranged first horizontal telescopic rod. The movable end of the first horizontal telescopic rod is arranged towards the direction where the opening is located. A push plate is fixedly connected to the movable end of the first telescopic rod. The push plate is horizontally arranged, and the thickness of the push plate is less than the height of the opening, and the width is less than the width of the opening, so that the push plate can respectively penetrate through the two openings along the horizontal direction.

[0014] Further, the transfer component includes a support column, a second horizontal telescopic rod arranged on the top of the support column, and a first vertical telescopic rod fixed to the movable end of the second horizontal telescopic rod. The projection of the moving path of the first vertical telescopic rod driven by the second horizontal telescopic rod on the surface of the workbench intersects with the moving path of the push plate and the upper surface of the placement rack. A grasping mechanism is fixed to the bottom end of the first vertical telescopic rod, and the grasping mechanism can grasp or release the label.

[0015] Further, the grasping mechanism includes a fixing plate and a suction cup. The fixing plate is horizontally arranged and connected to the bottom end of the first vertical telescopic rod. The suction cup is arranged at the bottom of the fixing plate, and the adsorption surface of the suction cup faces the surface of the workbench.

[0016] Further, the limiting component includes a third horizontal telescopic rod and a second vertical telescopic rod. The second vertical telescopic rod is fixed to the movable end of the third horizontal telescopic rod. The third horizontal telescopic rod is parallel to the first horizontal telescopic rod, so that the horizontal projection of the moving path of the second vertical telescopic rod intersects with the horizontal projection of the moving path of the first vertical telescopic rod on the upper surface of the placing rack;

[0017] A pressing member is arranged at the bottom end of the second vertical telescopic rod, and the pressing member does not affect the operation of the feeding component and the welding component.

[0018] Further, the pressing member includes a connecting block and two pressing pieces. The connecting block is connected to the second vertical telescopic rod. The pressing pieces are arranged horizontally in parallel. One end of each pressing piece is fixed to the side surface of the connecting block, and the bottom is located on the upper surface of the placing rack. The distance between the pressing pieces allows the grasping mechanism to pass through in the vertical direction.

[0019] Further, the welding component includes a fourth horizontal telescopic rod arranged on the workbench, a track mechanism arranged at the movable end of the fourth horizontal telescopic rod, a connecting rod installed on the track mechanism, and a welding torch arranged on the connecting rod. The fourth horizontal telescopic rod is arranged parallel to the second horizontal telescopic rod. The connecting rod is respectively connected to the track mechanism and the welding torch, so that the welding torch moves through the track mechanism, and the bottom end of the welding torch abuts against the position where the label is located on the surface of the support frame. The welding torch moves to the opposite side edges of the label respectively under the drive of the fourth horizontal telescopic rod and the track mechanism to perform welding.

[0020] Further, the track mechanism includes a guide rail perpendicular to the fourth horizontal telescopic rod and a slider movably arranged on the guide rail. The slider moves horizontally along the guide rail, and the whole formed by the guide rail and the slider moves under the drive of the fourth horizontal telescopic rod. One end of the connecting rod is fixed on the slider, and the other end is connected to the welding torch, so that the welding torch extends out of the surface of the workbench to the position where the mounting rack is located.

[0021] Further, a chute is arranged at the bottom of the fourth horizontal telescopic rod. The fixed end of the fourth horizontal telescopic rod is fixed at one end of the chute, and the movable end is connected with a support block. The support block is slidably installed on the chute to move freely along the chute. The track mechanism is arranged on the support block, and the moving direction of the track mechanism is perpendicular to the chute.

The placement rack is used to carry containers or workpieces with labels to be installed in different shapes. Then, the feeding component, the transfer component, the limiting component and the welding component cooperate with each other to complete the welding work of the labels. The present invention can cooperate with cylindrical pressure-resistant containers such as liquefied gas cylinders. Place the circular handle part at the top of the gas cylinder on the placement rack, and the fully automatic label welding can be completed, thus avoiding problems such as low efficiency, time-consuming and laborious, and high error rate caused by manual operation.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0030] As Figure 1As shown in the figure, an embodiment of the present invention provides a label rapid welding device, which includes a workbench 1, and a placement rack 2, a feeding assembly 3, a transfer assembly 4, a limiting assembly 5, and a welding assembly 6 respectively arranged on the workbench 1. In this embodiment, the product to be welded with the label is the circular grab part at the top of the liquefied gas bottle.

[0031] In this embodiment, the workbench 1 has a square tabletop structure, and its upper surface is horizontal for arranging each component. The placement rack 2 is arranged at one side edge of the workbench 1. The placement rack 2 is a horizontally arranged cylindrical structure or a flat plate structure. In this embodiment, the cylindrical structure is preferably adopted, and the axis of the cylinder is perpendicular to the vertical side surface on which it is installed, so that the top of the placement rack 2 corresponds to the upper surface position of the workbench 1. At this time, the product is the circular grab part at the top of the liquefied gas bottle. Then, the product is coaxially sleeved outside the placement rack 2, and one end of the product is closely attached to the side surface of the workbench 1 to complete the placement. The upward-facing arc surface on the outside of the product is used for welding with the label. The feeding assembly 3 and the transfer assembly 4 are arranged on the side of the workbench 1 far from the placement rack 2, and the limiting assembly 5 and the welding assembly 6 are arranged on the side of the workbench 1 close to the placement rack 2, and the limiting assembly 5 and the welding assembly 6 are respectively arranged on the opposite sides of the placement rack 2.

[0032] As Figure 2 shown, in the embodiment of the present invention, the feeding assembly 3 is arranged on the upper surface of the workbench 1, and the feeding assembly 3 automatically and continuously outputs single labels to the position where the transfer assembly 4 is located. Specifically, the feeding assembly 3 includes a vertically arranged feeding groove 31 and a pusher 32 arranged on the side far from the transfer assembly 4 relative to the feeding groove 31. The feeding groove 31 is a vertically arranged hollow cylindrical structure, and the cross-sectional shape inside it corresponds to the shape of the label, so that the label is restricted in the feeding groove 31 and can only move vertically. In this embodiment, the label is a square plate, so the feeding groove 31 is a square cylinder. Horizontally strip-shaped openings 311 are respectively arranged at the bottom of the feeding groove 31 corresponding to the opposite sides of the transfer assembly 4 and the pusher 32, and the openings 311 on both sides are arranged opposite to each other, and the size of the openings 311 is just enough for the label to pass horizontally.

[0033] The pusher 32 includes a first horizontal telescopic rod 321 arranged horizontally. The movable end of the first horizontal telescopic rod 321 is arranged towards the direction where the opening 311 is located. A strip-shaped connecting head 322 is fixedly connected to the movable end of the first telescopic rod. A push plate 323 is arranged on the side of the bottom of the connecting head 322 away from the first telescopic rod. The push plate 323 is horizontally and closely attached to the surface of the workbench 1. The thickness of the push plate 323 is less than the height of the opening 311, and the width is less than the width of the opening 311, so that the push plate 323 can pass through the two openings 311 horizontally respectively. In this way, when the labels are stacked vertically in the feeding groove 31, the relative two sides of the bottommost label correspond to the positions of the two openings 311. At this time, the first telescopic rod extends, allowing the push plate 323 to pass through the first opening 311, that is, to contact the label. Subsequently, the push plate 323 continues to move, pushing the label through the second opening 311 until the label reaches the position of the transfer assembly 4, completing one feeding. Then the push plate 323 retracts until it completely leaves the feeding groove 31, and the stacked labels drop under the action of gravity, and a new feeding can be prepared again.

[0034] The transfer assembly 4 is arranged corresponding to the feeding assembly 3, and transports the labels output by the feeding assembly 3 to the position where the placement rack 2 is located. In this embodiment, the transfer assembly 4 includes a support column 41, a second horizontal telescopic rod 42 arranged on the top of the support column 41, and a first vertical telescopic rod 43 fixed to the movable end of the second horizontal telescopic rod 42. The movement path of the first vertical telescopic rod 43 driven by the second horizontal telescopic rod 42 projects onto the surface of the workbench 1 and intersects with the movement path of the push plate 323 and the upper surface of the placement rack 2. A grasping mechanism 44 is fixed to the bottom end of the first vertical telescopic rod 43, and the grasping mechanism 44 can grasp or release the label.

[0035] In a further solution, the grasping mechanism 44 includes a fixing plate 441 and a suction cup 442. The fixing plate 441 is arranged horizontally and connected to the bottom end of the first vertical telescopic rod 43. The suction cup 442 is arranged at the bottom of the fixing plate 441, and the adsorption surface of the suction cup 442 faces the surface of the workbench 1. In this embodiment, an air extraction pipe 443 is also arranged above the suction cup 442. The middle of the air extraction pipe 443 is connected to the fixing plate 441, and the upper end of the air extraction pipe 443 is connected to an air extractor through a hose (not shown) to provide suction ability for the suction cup 442. When the feeding assembly 3 transports the label below the suction cup 442, the first vertical telescopic rod 43 controls the suction cup 442 to move downward to contact the upper surface of the label, thereby adsorbing the label to achieve grasping. Subsequently, the first vertical telescopic rod 43 moves upward to lift the label, and the second horizontal telescopic rod 42 moves to move the first vertical telescopic rod 43 and the label as a whole to above the placement rack 2. The first vertical telescopic rod 43 moves downward again to move the label to the product surface arranged on the placement rack 2.

[0036] The limiting component 5 is arranged in cooperation with the placement rack 2. The limiting component 5 fixes and limits or releases the limit of the label placed on the placement rack 2, and does not affect the operation of the welding component 6 at the same time. The limiting component 5 includes a third horizontal telescopic rod 52 and a second vertical telescopic rod 53. The second vertical telescopic rod 53 is fixed on the movable end of the third horizontal telescopic rod 52. The third horizontal telescopic rod 52 is parallel to the first horizontal telescopic rod 321, so that the horizontal projection of the moving path of the second vertical telescopic rod 53 intersects with the horizontal projection of the moving path of the first vertical telescopic rod 43 on the upper surface of the placement rack 2. In this embodiment, since the placement rack 2 is arranged on the side of the workbench 1 and is located outside the workbench 1, a support 51 parallel to the placement rack 2 is also arranged at the bottom of the third horizontal telescopic rod 52 on the side of the workbench 1.

[0037] Furthermore, a pressing member 54 is arranged at the bottom end of the second vertical telescopic rod 53, and the pressing member 54 does not affect the operation of the feeding component 3 and the welding component 6. Preferably, the pressing member 54 includes a connecting block 541 and two pressing pieces 542. The connecting block 541 is connected to the second vertical telescopic rod 53. The pressing pieces 542 are arranged horizontally in parallel. One end of each pressing piece 542 is fixed to the side surface of the connecting block 541, and the bottom is located on the upper surface of the placement rack 2. The distance between the pressing pieces 542 allows the grasping mechanism 44 to pass through in the vertical direction. That is, the distance between the two pressing pieces 542 does not affect the passage of the suction cup 442. Therefore, when the suction cup 442 adsorbs the label and places it on the surface of the product to be processed, the limiting component 5 starts to work. The pressing member 54 is moved above the label through the third horizontal telescopic rod 52. At this time, the two pressing pieces 542 respectively pass through both sides of the air extraction pipe 443, without affecting the operation of other components of the grasping component. Subsequently, the second vertical telescopic rod 53 drives the pressing pieces 542 to move downward to press tightly on the label, then the first vertical telescopic rod 43 can drive the suction cup 442 to move upward, so that the suction cup 442 passes through between the two pressing pieces 542, and the label is separated from the suction cup 442 due to the fixation of the pressing pieces 542.

[0038] Preferably in this embodiment, a sponge gasket is arranged at the bottom of the pressing piece 54, so that the circular arc-shaped surface of the product is in closer contact with the pressing piece 54, avoiding the problem that the pressing piece 54 slides on the product, resulting in displacement during the welding process and affecting the welding accuracy. In addition, in this embodiment, considering that the welding surface of the product is an arc surface, and the label is usually processed into a flat thin sheet, the bottom of the pressing piece 54 can be set as an arc surface matching the shape of the welding surface, so as to bend the label during the process of fixing the label and make it closely adhere to the surface of the product, making the welding more firm. When the area of the label is extremely small relative to the welding surface of the product, the radian of the welding surface can be ignored at this time, and it can also be directly pressed for welding, and the stability of the label is ensured by the thickness of the weld.

[0039] Such as Figure 3As shown, the welding assembly 6 is arranged relative to the limiting assembly 5. When the limiting assembly 5 fixes and limits the label, the welding assembly 6 abuts against the label for welding processing. When the limiting assembly 5 releases the limit, the welding assembly 6 moves away from the label. Specifically, the welding assembly 6 includes a fourth horizontal telescopic rod 63 arranged on the workbench 1, a track mechanism 64 arranged at the movable end of the fourth horizontal telescopic rod 63, a connecting rod 65 installed on the track mechanism 64, and a welding torch 66 arranged on the connecting rod 65. The fourth horizontal telescopic rod 63 is arranged parallel to the second horizontal telescopic rod 42. The connecting rod 65 is respectively connected to the track mechanism 64 and the welding torch 66, so that the welding torch 66 moves through the track mechanism 64, and the bottom end of the welding torch 66 abuts against the position of the label on the surface of the support frame. The welding torch 66 moves to the opposite side edges of the label respectively under the drive of the fourth horizontal telescopic rod 63 and the track mechanism 64 for welding.

[0040] Furthermore, the track mechanism 64 includes a guide rail 641 arranged perpendicular to the fourth horizontal telescopic rod 63 and a slider 642 movably arranged on the guide rail 641. The slider 642 moves in the horizontal direction along the guide rail 641, and the whole formed by the guide rail 641 and the slider 642 moves under the drive of the fourth horizontal telescopic rod 63. One end of the connecting rod 65 is fixed on the slider 642, and the other end is connected to the welding torch 66, so that the welding torch 66 extends out of the surface of the workbench 1 to the position where the mounting frame is located. Considering that the placement rack 2 is located outside the workbench 1 in this embodiment, the connecting rod 65 adopts a horizontal L-shaped bending structure, so as to extend the welding torch 66 out of the upper surface of the workbench 1 and extend to the side of the placement rack 2 away from the limiting assembly 5. Preferably, in this embodiment, the guide rail 641 adopts a ball screw guide rail 641, and the slider 642 is connected to the ball screw guide rail 641 through a ball bearing. One end of the guide rail 641 is connected with a motor to provide power.

[0041] As Figure 4As shown in the figure, after the label is fixed, the fourth horizontal telescopic rod 63 extends first, so that the welding torch 66 is aligned with the edge of the label on the side away from the workbench 1. Then the motor drives the ball screw guide rail 641 to rotate, driving the slider 642 to move along the guide rail 641 towards the product direction, driving the welding torch 66 to move along the straight line where the label edge is located. When the welding torch 66 moves to the end point of the label edge, welding starts and ends when the welding torch 66 moves to the other end of the label edge. Subsequently, the fourth horizontal telescopic rod 63 contracts so that the welding torch 66 is aligned with the edge end point of the label on the side close to the workbench 1, and welding starts again. At the same time, the motor rotates in the reverse direction, driving the slider 642 to move along the direction away from the product through the ball screw guide rail 641, so that the welding torch 66 completes the welding of the other side edge of the label. Finally, the slider 642 continues to move so that the welding torch 66 completely disengages from the position above the placement rack 2, and then the second vertical telescopic rod 53 raises the pressing member 54 and the third horizontal telescopic rod 52 contracts the pressing member 54 away from the position above the placement table, and then the cylindrical product can be drawn outwards.

[0042] In a preferred solution, a chute 62 is provided at the bottom of the fourth horizontal telescopic rod 63. The fixed end of the fourth horizontal telescopic rod 63 is fixed at one end of the chute 62, and the movable end is connected with a support block 621. The support block 621 is slidably installed on the chute 62 to move freely along the chute 62. The track mechanism 64 is arranged on the support block 621, and the moving direction of the track mechanism 64 is perpendicular to the chute 62. Considering that there is also a movable part on the track mechanism 64 and the welding torch 66 that needs to move is connected at the same time, in this way, when the track mechanism 64 is driven by the fourth horizontal telescopic rod 63 to move, it can be more stable and avoid shaking left and right, which affects the welding accuracy. At the same time, a support table 61 is also provided below the chute 62 to lift the whole chute 62 to match the length of the welding torch 66.

[0043] As a preferred implementation manner, in this embodiment, the first horizontal telescopic rod 321, the second horizontal telescopic rod 42, the third horizontal telescopic rod 52, the fourth horizontal telescopic rod 63, the first vertical telescopic rod 43, and the second vertical telescopic rod 53 are all telescopic rods of an electric cylinder structure.

[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the purpose and scope of the technical solutions of the present invention, and they should all be covered by the scope of the claims of the present invention.
