Description

Technical Field

[0001] This utility model belongs to the field of automated assembly technology of urine collection bags, and relates to a welding device, particularly an ultrasonic welding device. Background Technology

[0002] The urine collection bag consists of a urine bag and a bottle body, which is further divided into a bottle frame and a cap. Before assembling the cap with the bottle body, an air filter membrane needs to be welded to the opening of the cap, typically using ultrasonic welding. The current welding station includes a cap feeding mechanism, an air filter membrane feeding mechanism, a cap transfer mechanism, an air filter membrane transfer mechanism, a welding carrier, and an ultrasonic welding gun. The cap feeding mechanism loads the cap, which is then picked up and transported to the welding carrier. The air filter membrane feeding mechanism outputs the air filter membrane, which is then transported to the opening of the cap on the welding carrier. The ultrasonic welding gun then welds the two parts together, and finally, the membrane is unloaded and moved to the next station. This air filter membrane welding requires multiple mechanisms to work together, resulting in long cycle times between them and low processing efficiency. Moreover, in such a welding station, the air filter membrane is not precisely aligned when placed on the bottle cap, and the position to be welded on the bottle cap is not aligned with the ultrasonic welding head, which may lead to unsatisfactory welding results, such as weld position displacement or skewness. Summary of the Invention

[0003] The purpose of this invention is to address the aforementioned problems in the existing technology by proposing an ultrasonic welding device. It solves the technical problem of how to simultaneously improve the efficiency and yield of the welding station.

[0004] The objective of this utility model can be achieved through the following technical solutions: An ultrasonic welding apparatus is disposed on one side of a conveyor line, the conveyor line having an in-line carrier that travels in a straight line. This welding device includes an ultrasonic welding head, a conveying assembly, and a positioning carrier, all positioned on the same side of the conveyor line. The positioning carrier is located below the ultrasonic welding head and parallel to the carriers arranged on the line. The conveying assembly is used to reciprocate between the carriers on the line and the positioning carrier to move bottle caps back and forth. The conveying assembly includes a pressure block and a feeding section for gripping or picking up material bottle caps, the pressure block being configured to press against the filter membrane of the material bottle caps as the feeding section transfers the material bottle caps; The positioning carrier has a reference positioning part and a movable positioning part at both ends of its length direction. The reference positioning part and the movable positioning part are arranged opposite to each other and the movable positioning part can move toward the reference positioning part. The positioning carrier has a centering limit block on both sides of its width direction and the two centering limit blocks can move closer to or further away from each other.

[0005] This ultrasonic welding device is installed on one side of the conveyor bottle cap. The material bottle caps are transported to the conveyor line by an online carrier for welding. The material bottle caps have already had filter membranes placed on them at the previous station. When they arrive at the transport component, they are transported to the positioning carrier for welding. During the transport process, the pressure block on the transport component can hold down the filter membrane placed on the bottle cap to prevent it from falling off. After welding is completed at the positioning carrier, the material is transported back to the online carrier by the transport component and transferred to the next station. This welding station design greatly improves production efficiency while ensuring a high yield rate.

[0006] The positioning carrier of this application is used to place the bottle cap of the material to be welded. The positioning carrier has a reference positioning part and a movable positioning part. The side of the reference positioning part is close to the position to be welded on the bottle cap, that is, the location of the filter membrane. The reference positioning part is equivalent to a reference. The movable positioning part pushes the other end of the bottle cap so that the end of the bottle cap where the position to be welded is close to the reference positioning part and aligned in the left and right direction. The positioning carrier also has a centering limit block. The two centering limit blocks can approach each other and clamp the middle position of the bottle cap so that its front and back position is centered and aligned. Such tight limiting can make the position to be welded, that is, the location of the filter membrane, precisely aligned with the ultrasonic welding head, thereby improving the welding yield.

[0007] In the ultrasonic welding device described above, the conveying assembly includes a rotary cylinder and two material handling parts, which are arranged opposite to each other and can rotate and exchange positions under the drive of the rotary cylinder.

[0008] The material handling component of this application consists of two symmetrically arranged picking units that can rotate and exchange positions symmetrically. This means that by simply setting the distance between the positioning carrier and the carrier on the line to correspond to the positions of the two picking units, the material can be rotated and handled, which is highly efficient.

[0009] In the aforementioned ultrasonic welding device, the conveying assembly includes a frame, a lifting cylinder is mounted on the top of the frame, and a rotary cylinder is connected to the output end of the lifting cylinder and can be raised and lowered under the drive of the lifting cylinder.

[0010] The two material handling parts of this application are connected to a rotary cylinder, which is connected to a lifting cylinder for lifting and lowering. The two material handling parts can simultaneously lift and lower the material bottle caps on the line carrier and the positioning carrier, which results in high synchronization and simple and efficient movement.

[0011] In the aforementioned ultrasonic welding device, a mounting plate is fixed to the rotating end of the rotary cylinder. The mounting plate has two mounting ends arranged opposite to each other. The material handling part is a suction cup assembly, and the two suction cup assemblies are respectively fixed to the mounting ends. A telescopic cylinder is provided on one side of the suction cup assembly on the mounting end. The pressure block is fixed to the push rod of the telescopic cylinder and can extend and retract horizontally under the drive of the telescopic cylinder to press the filter membrane on the material bottle cap.

[0012] The pressing blocks in this application are all located on one side of each material picking section. They are driven to move horizontally above the filter membrane position by a telescopic cylinder. The material picking section is a suction cup group. The suction cup group picks up the material bottle cap. When the material bottle cap is picked up, it floats upward and rests against the pressing block, thereby pressing the filter membrane onto the pressing block. This ensures that the position of the filter membrane does not change during the movement, ensuring stable welding and a high yield.

[0013] In the ultrasonic welding device described above, the mounting end has a blocking part protruding on both sides of the suction cup assembly arrangement direction. When the suction cup assembly adsorbs the material bottle cap, the upper surface of the material bottle cap and the bottom surface of the blocking part form a blocking trend.

[0014] The material handling part of this application is a suction cup assembly, and a blocking part is provided on the side of the suction cup assembly. When adsorbing the material bottle cap, the blocking part limits and blocks the floating position of the material bottle cap, so as to improve the positional accuracy of picking up and putting down the material.

[0015] In the ultrasonic welding device described above, the bottom surface of the pressure block and the bottom surface of the blocking part are on the same horizontal plane.

[0016] The bottom surface of the pressing block and the blocking part of this application are on the same horizontal plane so as to make synchronous contact with the material bottle cap, so as to prevent the pressing block from excessively squeezing the filter membrane and causing damage, thereby improving the yield.

[0017] In the aforementioned ultrasonic welding device, the positioning carrier includes a base, the reference positioning part is located at one end of the base and protrudes upward, the movable positioning part is located at the other end of the base relative to the reference positioning part, the movable positioning part is a push rod, the push rod is connected to a drive cylinder, and is pushed by the drive cylinder to extend towards the reference positioning part.

[0018] In the aforementioned ultrasonic welding device, an arc-shaped protrusion protrudes upward from the end of the base opposite to the reference positioning part. The arc-shaped protrusion and the reference positioning part surround and form a receiving groove. The arc-shaped protrusion has a notch, and the push rod can extend into the inside of the receiving groove from the notch.

[0019] The arc-shaped protrusion and the reference positioning part surround to form a receiving groove. The receiving groove can guide and limit the material bottle caps that are picked up and put in. The receiving groove is used for initial limiting, and then the push rod and the central limiting clamp are used for further precise positioning. This makes it easy to pick up and put in while ensuring accurate positioning.

[0020] In the ultrasonic welding device described above, the centering limiting block is located on both sides of the base between the reference positioning part and the movable positioning part, and the two centering limiting blocks can approach each other to clamp the material bottle cap.

[0021] In the aforementioned ultrasonic welding device, the base is provided with an air blowing component and a dust suction component at intervals on opposite sides near the reference positioning part.

[0022] This application also incorporates air blowing and dust suction components on the base, which remove dust and other impurities from the filter membrane and the welding area by blowing and suction, thereby further improving the welding yield.

[0023] Compared with existing technologies, the advantages of this product are: 1. The material handling component of this application uses two rotatable material handling parts to symmetrically rotate and exchange the positioning carrier and the material bottle cap on the line carrier. It is also equipped with a pressure block to press the filter membrane placed on the material bottle cap, so as to realize rapid repositioning for welding. After welding, it can be quickly reset and transferred. Such welding station has high production efficiency.

[0024] 2. The positioning carrier of this application uses the receiving groove to initially position and place the material bottle cap. It is also equipped with a movable positioning part and a reference positioning part to align the position in the left and right directions. In addition, a centering limit block is set to clamp the middle position of the material bottle cap so that its front and back positions are centered and aligned. This tight positioning ensures that the position to be welded, i.e. the position of the filter membrane, is precisely aligned with the ultrasonic welding head, thereby improving the welding yield.

Detailed Implementation

[0027] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0028] like Figure 1 An ultrasonic welding device is shown, which is set on one side of a conveyor line 1. The conveyor line 1 has a rotating belt, and several online carriers 11 are fixed at intervals on the belt. The rotating belt drives the online carriers 11 to be transported in a straight line. At the front end of the conveyor line 1, there is a feeding mechanism that can feed bottle caps to the online carriers 11. The bottle caps are transported in a straight line by the online carriers 11. Some workstations related to bottle cap assembly or processing are arranged along both sides of the conveyor line 1. The ultrasonic welding device is set on one side of the belt and is called the welding workstation. When the online carrier 11 moves to the welding workstation, it stops, and the bottle caps on the online carrier 11 can be removed for welding. This assembly line welding method design can greatly improve efficiency.

[0029] like Figure 1 and Figure 2 As shown, this ultrasonic welding device includes an ultrasonic welding assembly (including an ultrasonic welding head 2), a conveying assembly 3, and a positioning carrier 4. The ultrasonic welding assembly, including the ultrasonic welding head 2, is used for welding; this is existing mature technology and will not be elaborated upon here. The positioning carrier 4 is located below the ultrasonic welding head 2 and is used to position the material bottle caps for precise positioning welding. The conveying assembly 3 is located between the positioning carrier 4 and the conveyor line 1, and is used to reciprocate between the positioning carrier 4 and the online carrier 11 on the conveyor line 1 to move the material bottle caps to be welded from the online carrier 11 to the positioning carrier 4, or to move the welded material bottle caps from the positioning carrier 4 back to the online carrier 11 for continued transmission. This simplifies the old welding method shown in the background art and significantly improves production efficiency.

[0030] like Figure 3 , Figure 5 and Figure 6The specific structure and arrangement of the positioning carrier 4 in this application are as follows: The positioning carrier 4 is located below the ultrasonic welding head 2. The structure of the positioning carrier 4 is similar to that of the online carrier 11, and both are designed to mimic the outer contour of the material bottle cap, which is advantageous for accommodating the placement of the material bottle cap. This design facilitates the transfer and placement of the material bottle cap between the positioning carrier 4 and the online carrier 11, resulting in good stability. The positioning carrier 4 and the online carrier 11 are designed parallel to each other and face opposite directions. This design is adapted to the rotary conveying component 3, and works in conjunction with the conveying component 3 to improve the overall material switching efficiency and thus improve the overall production efficiency. The specific arrangement and structure of the conveying component 3 are described below.

[0031] Furthermore, the positioning carrier 4 includes a base 44, a reference positioning part 41 located at one end of the base 44 and protruding upward, and a movable positioning part 42 located at the other end of the base 44 opposite to the reference positioning part 41. The movable positioning part 42 is a push rod connected to a drive cylinder 45. The push rod is pushed by the drive cylinder 45 to extend towards the reference positioning part 41. In order to improve the welding accuracy, the reference positioning part 41 is set to set the reference, so that the end of all the material bottle caps that are taken off the line and placed in the positioning carrier 4 can be accurately fixed near the welding end, which makes it convenient for the ultrasonic welding head 2 to fall directly for welding without the need for position adjustment, thereby improving the welding yield.

[0032] Furthermore, an arc-shaped protrusion 46 protrudes upward from the end of the base 44 opposite to the reference positioning part 41. The arc-shaped protrusion 46 and the reference positioning part 41 surround and form a receiving groove 47. The arc-shaped protrusion 46 has a notch 461, through which the push rod can extend into the inside of the receiving groove 47. The receiving groove 47 formed between the arc-shaped protrusion 46 and the reference positioning part 41 can guide and limit the material bottle caps being picked up and placed. Initial positioning is achieved through the receiving groove 47, followed by further precise positioning through the push rod and the central limiting clamp 43. This facilitates picking up and placing while ensuring precise positioning, reducing the probability of failure and further improving the yield rate.

[0033] Furthermore, at the center of the bottom, there are notches 461 on both sides between the reference positioning part 41 and the movable positioning part 42. Movable centering limit clamps 43 are provided at the notches 461. The bottom of the two centering limit clamps 43 are connected to the two-finger cylinders 48. The two-finger cylinders 48 drive the opening and closing. The two-finger cylinders 48 are fixed to the bottom of the base 44. The upper ends of the centering limit clamps 43 are located on both sides of the base 44 between the reference positioning part 41 and the movable positioning part 42 at the receiving groove 47 and are close to each other to clamp the material bottle cap. This ensures that the material bottle cap is in the correct position and avoids tilting. It also makes the material bottle cap centered to ensure accurate welding position of the finished product.

[0034] Furthermore, the base 44 is provided with air blowing components 5 and dust suction components 6 at intervals on opposite sides near the reference positioning part 41. This application also designs air blowing components 5 and dust suction components 6 on the base 44 to remove dust and other impurities from the filter membrane and the position to be welded by blowing and suction, thereby further improving the welding yield.

[0035] like Figure 2 and Figure 4 As shown, the specific structure and arrangement of the conveying component 3 of this application are as follows: The conveying component 3 is used to reciprocate between the online carrier 11 and the positioning carrier 4 to transport material bottle caps. The conveying component 3 includes a pressing block 31 and a material picking part 32 for clamping or sucking up material bottle caps. The pressing block 31 is configured to press against the filter membrane of the bottle cap when the material picking part 32 moves the material bottle cap. The positioning carrier 4 has a reference positioning part 41 and a movable positioning part 42 at both ends in its length direction. The reference positioning part 41 and the movable positioning part 42 are arranged opposite to each other and the movable positioning part 42 can move toward the reference positioning part 41. The positioning carrier 4 has a centering limiting clamp 43 on both sides in its width direction and the two centering limiting clamps 43 can move closer to or further away from each other. This ultrasonic welding device is installed on one side of the conveyor bottle cap. The material bottle cap is conveyed to the conveyor line 1 by the online carrier 11 for welding. The material bottle cap has a filter membrane placed on it at the previous station. When it reaches the position of the conveying component 3, it is transported by the conveying component 3 to the positioning carrier 4 for welding. During the transportation process, the pressure block 31 on the conveying component 3 can press down the filter membrane placed on the bottle cap to prevent it from falling off. After welding is completed at the positioning carrier 4, it is transported back to the online carrier 11 by the conveying component 3 for transmission to the next station. This welding station design greatly improves production efficiency while ensuring the yield rate.

[0036] Furthermore, the conveying assembly 3 includes a rotary cylinder 33 and two picking-up sections 32. The two picking-up sections 32 are arranged opposite each other and can rotate and exchange positions under the drive of the rotary cylinder 33. The conveying assembly 3 of this application consists of two symmetrically arranged picking-up sections 32, which can rotate and exchange positions symmetrically. In this way, it is only necessary to set the distance between the positioning carrier 4 and the online carrier 11 to correspond to the positions of the two picking-up sections 32 to realize the rotational conveying of materials, which is highly efficient.

[0037] Furthermore, the handling assembly 3 includes a frame 34, with a lifting cylinder 35 mounted on the top of the frame 34. A rotary cylinder 33 is connected to the output end of the lifting cylinder 35 and can move up and down under the drive of the lifting cylinder 35. The two material handling parts 32 of this application are connected to the rotary cylinder 33, which is integrally connected to the lifting cylinder 35 for lifting. The two material handling parts 32 can simultaneously lift and lower the material bottle caps on the line carrier 11 and the positioning carrier 4, resulting in high synchronization and simple, efficient movement.

[0038] Furthermore, a mounting plate 36 is fixed to the rotating end of the rotary cylinder 33. The mounting plate 36 has two mounting ends 361 arranged opposite to each other. The material picking part 32 is a suction cup assembly, and the two suction cup assemblies are respectively fixed to the mounting ends 361. A telescopic cylinder 37 is provided on one side of the suction cup assembly on the mounting end 361. The aforementioned pressing block 31 is fixed to the push rod of the telescopic cylinder 37 and can be horizontally extended and retracted in the extension direction of the two material picking parts 32 under the drive of the telescopic cylinder 37, for pressing the filter membrane on the material bottle cap. The pressing block 31 of this application is provided on one side of each material picking part 32. It is driven by the telescopic cylinder 37 to move horizontally above the position of the filter membrane. The material picking part 32 is a suction cup assembly. The suction cup assembly picks up the material bottle cap. When the material bottle cap is picked up, it floats upward and rests against the pressing block 31, thereby pressing the filter membrane onto the clamping block. This ensures that the position of the filter membrane does not change during the movement, ensuring stable welding and a high yield.

[0039] Furthermore, the mounting end 361 has protruding abutment portions 362 on both sides of the suction cup assembly arrangement direction. When the suction cup assembly adsorbs the material bottle cap, the upper surface of the material bottle cap and the bottom surface of the abutment portion 362 form a blocking tendency. The material picking part 32 of this application is a suction cup assembly, and the abutment portion 362 is provided on the side of the suction cup assembly. When adsorbing the material bottle cap, the abutment portion 362 limits and blocks the floating position of the material bottle cap to improve the positional accuracy of picking and placing materials.

[0040] Furthermore, the bottom surface of the pressing block 31 and the bottom surface of the blocking part 362 are on the same horizontal plane. The bottom surfaces of the pressing block 31 and the blocking part 362 are on the same horizontal plane so as to make synchronous contact with the material bottle cap, preventing the pressing block 31 from excessively squeezing the filter membrane and causing damage, thereby improving the yield rate.

[0041] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
