Description

Technical Field

[0001] This invention relates to the technical field of welding electric mechanisms, and more particularly to an ultrasonic welding apparatus for electric mechanisms. Background Technology

[0002] Currently, in the assembly process of existing electric mechanism products, the assembly and welding of the upper and lower covers are usually completed manually or in semi-automatic stations. The transfer, positioning, clamping, and welding actions between processes are scattered, and operators need to repeatedly perform manual alignment, placement, and confirmation, resulting in limited overall cycle time, high labor intensity, and poor cycle time consistency. At the same time, because the product is prone to displacement or posture changes during transportation to the welding position, the accuracy and stability of manual alignment are difficult to guarantee, affecting the subsequent welding quality. Furthermore, the ability of humans to handle multiple actions simultaneously is limited, which can easily lead to quality problems such as omissions, misalignments, and weak welds. As product structures become more refined and the required welding consistency increases, traditional methods relying on manual labor or simple tooling are no longer sufficient to meet the demands for efficiency, yield, and automation. Summary of the Invention

[0003] To address the problems of low efficiency, unstable positioning, inconsistent cycle time, and susceptibility of welding quality to human factors in traditional manual assembly and welding processes, this application provides an ultrasonic welding device with an electric mechanism.

[0004] The above-mentioned objective of this application is achieved through the following technical solution: An ultrasonic welding apparatus for an electric mechanism, the ultrasonic welding apparatus for an electric mechanism comprising: The conveying mechanism includes a belt conveying component and a limiting component located in the gap between two belts in the belt conveying component; A positioning component is used to place the product top cover and the product bottom cover, and is placed in the belt conveyor component for forward and backward transmission; An ultrasonic welding head is positioned above the limiting component, and the gap between the ultrasonic welding head and the limiting component is a welding station, through which the positioning component is movably inserted. The clamping mechanism is located on one side of the belt conveyor component; When the positioning component is detected to be located at the welding station, the limiting component restricts the positioning component from continuing to move forward and backward, and then pushes upward against the positioning component to disengage from the belt conveyor component. The clamping mechanism clamps the product top cover and places it on the product bottom cover. The ultrasonic welding head presses down to complete the welding of the product top cover and the product bottom cover.

[0005] By adopting the above technical solutions, and by constructing a continuously cooperating automated mechanism between conveying, limiting, positioning, clamping and welding, the product can automatically stop, automatically lift, automatically put on the cover and immediately enter the welding process after entering the welding station. This ensures the stability of the station cycle and the alignment accuracy, eliminates the errors caused by manual alignment, and significantly improves welding consistency, yield and overall production efficiency.

[0006] Preferably, the positioning component includes a positioning block and a slide. The slide is placed on the belt conveyor for forward and backward transmission and is fixedly connected to the positioning block by bolts. The positioning block is fitted with a product top cover and a product bottom cover.

[0007] By adopting the above technical solution, a sliding table is used to support the positioning block and move with the belt, so that the product can maintain a stable posture throughout the conveying process. The structure of the positioning block ensures that the upper and lower covers of the product are in a fixed position before entering the welding station, thereby improving the anti-deviation capability during the transmission process and providing a reliable basic positioning accuracy for subsequent automatic cover placement and welding.

[0008] Preferably, the positioning block is provided with positioning grooves and positioning bosses at intervals. The positioning grooves are positioned and engaged with the lower cover of the product, and the positioning bosses are positioned and engaged with the upper cover of the product. The clamping mechanism is located on the side of the belt conveyor component near the positioning bosses.

[0009] By adopting the above technical solution, complementary grooves and protrusions are set on the positioning block, so that the upper and lower covers of the product can be automatically aligned during clamping, ensuring accurate alignment between the clamped upper and lower covers; at the same time, the clamping mechanism is arranged on the side close to the positioning protrusion, so that the gripper can complete the grasping and placing action with the shortest movement path, thereby further improving the stability and efficiency of automatic cover placement.

[0010] Preferably, a clamping component is provided on one side of the belt conveyor component. When the positioning component disengages from the belt conveyor component, the pressing surface of the clamping component presses down to abut against the slide table, thereby positioning and stabilizing the slide table.

[0011] By adopting the above technical solution, the pressing component is used to press down the slide after the positioning component is removed from the belt, which can prevent the slide from shaking or slightly displacing due to the loss of the conveyor belt support, so that the product maintains a highly stable posture at the moment of welding, thereby improving the repeatability of the welding head pressing process and the consistency of welding strength.

[0012] Preferably, the clamping assembly includes a first lifting cylinder and a right-angle pressure plate. The driving end of the first lifting cylinder is connected to one end of the right-angle pressure plate to drive the right-angle pressure plate to move up and down. The other end of the right-angle pressure plate is parallel to the side of the slide table connected to the positioning block to fit the slide table for positioning and stabilization.

[0013] By adopting the above technical solution, the right-angle pressure plate is driven by the lifting cylinder, so that the pressing action is carried out with controllable and repeatable force. The right-angle pressure plate and the slide table are kept parallel and in contact, so that no lateral force is introduced during the pressing process, ensuring that the slide table is locked in the predetermined position and improving the positioning reliability of the welding station.

[0014] Preferably, the other end of the right-angle pressure plate is provided with two spaced pressure strips, one end of which is integrally connected to each other. The gap width between the two pressure strips is greater than the width of the positioning block, so as to make way for the positioning block and make the pressure strip fit against the positioning block, thereby cooperating to position and stabilize the slide.

[0015] By adopting the above technical solution, the two spaced-apart pressure strips maintain the pressure surface while making room for the positioning block, so that the pressing structure will not interfere with the product placement area and can directly fit the positioning block to achieve a stable lock, thereby ensuring the stability of the entire process of the top cover placement, alignment and welding, while avoiding damage to the product by the pressure strips.

[0016] Preferably, the belt conveyor is provided with a position sensing component electrically connected to the limiting component, and the detection area of ​​the position sensing component covers the welding station to detect whether the positioning component is located at the welding station.

[0017] By adopting the above technical solution and setting position sensing components on the belt conveyor, the system can detect in real time whether the positioning component has accurately reached the welding station, thereby realizing closed-loop control of the automated cycle time, so that the limit, lifting, clamping and welding actions are triggered at the right time, improving the overall reliability and synchronization of the equipment operation.

[0018] Preferably, the position sensing component includes a connecting block, a vertical rod, and a sensing probe. The connecting block is detachably connected to the belt conveyor component, the vertical rod is inserted into the connecting block, and the sensing probe is located at the end of the vertical rod near the ultrasonic welding head.

[0019] By adopting the above technical solution, and using a detachable combination structure of connecting blocks, vertical rods and probes, the height and position of the sensing probe can be flexibly adjusted, so that the detection area accurately covers the welding station, while facilitating maintenance and replacement, and ensuring the sensitivity and long-term stability of the station detection.

[0020] Preferably, the clamping mechanism includes a lifting component, a translation component, and a clamping component. The lifting component is connected to the translation component to drive the translation component to move toward or away from the positioning component. The translation component is connected to the clamping component to drive the clamping component to move along both sides of the belt conveyor component. The clamping component is used to clamp the product cover placed on the positioning component.

[0021] By adopting the above technical solution, through the coordination of the translation component, the lifting component and the gripping component, the gripping mechanism can achieve compound movement in different directions, ensuring that the upper cover can be accurately gripped and placed on the lower cover in a controlled trajectory, which significantly improves the reliability of the automatic cover placement action, avoids the occurrence of misalignment, tilting or misalignment, and thus improves the welding success rate and cycle consistency.

[0022] In summary, this application includes at least one of the following beneficial technical effects: This application integrates the previously manual transportation, alignment, lid placement, and welding processes into a continuous, coordinated mechanism that automatically conveys, limits, lifts, positions, and welds the entire welding process. This is achieved through a streamlined automated chain comprised of a conveyor mechanism, limiting components, a wearable positioning component, a clamping mechanism, and an ultrasonic welding head. Specifically, after the positioning component arrives at the welding position via belt conveyor, the limiting component actively stops its further movement and simultaneously lifts it upwards, detaching the platform from the belt and placing it in a stable welding posture. The clamping mechanism then automatically grasps the product's top cover and accurately places it on the bottom cover. The welding head then directly aligns with the positioned product for welding, eliminating the need for manual alignment or clamping. This not only achieves integrated automatic connection from conveying, alignment, lid placement to welding but also ensures that each product is in a stable and consistent position at the moment of welding, significantly improving assembly cycle time and avoiding quality problems such as eccentricity, misalignment, and omissions caused by manual operation. This results in an overall improvement in welding consistency, processing efficiency, and automation. Attached Figure Description

[0026] The present application will be further described in detail below with reference to the accompanying drawings.

[0027] In one embodiment, such as Figure 1 As shown, this application discloses an ultrasonic welding apparatus for an electric mechanism, the ultrasonic welding apparatus for an electric mechanism comprising: The conveying mechanism 1 includes a belt conveying component 11 and a limiting component 12 located in the gap between two belts in the belt conveying component 11; Positioning component 2 is used to place the product top cover and the product bottom cover, and is placed in the belt conveyor component 11 for front and rear transmission; The ultrasonic welding head 5 is positioned above the limiting component 12. The gap between the ultrasonic welding head 5 and the limiting component 12 is the welding station, and the positioning component 2 is movably inserted into the welding station. The clamping mechanism 6 is located on one side of the belt conveyor component 11; When the positioning component 2 is detected to be located at the welding station, the limiting component 12 restricts the positioning component 2 from continuing to move forward and backward, and then pushes the positioning component 2 upward to disengage from the belt conveyor component 11. The clamping mechanism 6 clamps the product top cover and places it on the product bottom cover. The ultrasonic welding head 5 presses down to complete the welding of the product top cover and the product bottom cover.

[0028] In this embodiment, the ultrasonic welding device with an electric mechanism mainly consists of a conveying mechanism 1, a positioning component 2, an ultrasonic welding head 5, a clamping mechanism 6, and a limiting component 12 cooperating with it, forming a continuous operation link. The conveying mechanism 1 includes a belt conveyor 11, and a limiting component 12 is provided between the two belts of the belt conveyor 11. The belt conveyor 11 is responsible for the kinetic energy output of transporting the product from the previous station to the welding station, while the limiting component 12 is placed at the position of the belt gap. The limiting component 12 is driven to rise and fall by a second lifting cylinder, so that when the positioning component 2 reaches the predetermined station, it can mechanically block the movement of the positioning component 2, and further lift the positioning component 2 upward, so that the positioning component 2 is freed from the support of the belt conveyor 11, thereby forcing it into the stable posture required for welding. The positioning component 2 carries the upper cover and lower cover of the product, and its lower structure can be placed on the belt conveyor 11 and transported back and forth by the movement of the belt. When the positioning component 2 moves to the vertical position of the welding station under the push of the belt conveyor 11, the limiting component 12 first stops the positioning component 2 from moving forward. Then the limiting component 12 pushes upward against the bottom of the positioning component 2, slowly lifting it away from the belt conveyor 11, so that the positioning component 2 changes from the follow-up conveying state to the stable suspension state, thereby avoiding the vibration error caused by the continuous movement of the belt conveyor 11, and keeping the positioning component 2 fixed and without displacement during welding.

[0029] The ultrasonic welding head 5 is fixedly installed above the limiting component 12, forming a vertical welding station between them. During the conveying phase, the positioning component 2 passes forward from below this station. After the positioning component 2 is lifted into position by the limiting component 12, its upper surface forms a stable welding gap with the initial position of the welding head, allowing the welding head to precisely press against the product's upper and lower covers during its vertical descent. The function of the welding head is to perform ultrasonic welding on the assembled product's upper and lower covers, achieving a tight fusion of the two products through the high-frequency vibration and pressing force of the welding head.

[0030] The gripping mechanism 6 is located on one side of the belt conveyor 11. Its function is to grip the top cover of the product from the loading side and accurately place it on the bottom cover of the product carried in the positioning component 2 after the positioning component 2 has been stably stopped at the welding station. After completing the translation, lifting, and gripping actions, the gripping mechanism 6 ensures that the top cover of the product is in a precise fit position before final welding, thus providing a reliable pre-assembly state for the ultrasonic welding head 5 to perform the welding action. The relative arrangement of the gripping mechanism 6 and the positioning component 2 means that the grippers do not need to move over a large range during gripping and placement, thereby improving the stability of the action and the consistency of the cycle.

[0031] During operation, the entire device first transports the positioning component 2, along with the product's lower cover it carries, from the front station to the welding station area via the conveyor mechanism 1. Once the positioning component 2 enters the detection range of the welding station, the limiting component 12 prevents it from moving further forward and, through an upward lifting action, disengages it from the dynamic support of the belt conveyor 11, forming a fixed welding support platform. At this point, the clamping mechanism 6 unfolds, accurately placing the product's upper cover onto the product's lower cover from the side. Subsequently, the ultrasonic welding head 5 presses down against the product's upper cover to achieve welding, ensuring a tight fusion between the upper and lower covers and completing the entire welding operation. The coordinated operation of these components ensures the product maintains a stable posture and precise position throughout the entire process of conveying, positioning, cover placement, and welding, improving overall welding quality and production efficiency.

[0032] Furthermore, the positioning component 2 includes a positioning block 21 and a slide 22. The slide 22 is placed on the belt conveyor component 11 for forward and backward transmission and is fixedly connected to the positioning block 21 by bolts. The positioning block 21 is fitted with a product top cover and a product bottom cover.

[0033] In this embodiment, the positioning component 2 is integrally formed by the positioning block 21 and the slide table 22. The slide table 22, as a follower base, is directly supported on the belt conveyor component 11, and the positioning component 2 moves linearly back and forth through the continuous operation of the belt conveyor component 11. The bottom structure of the slide table 22 adopts a combination of planar support and low-friction guide, so that it maintains a stable posture during belt conveying and will not tilt or jump significantly due to fluctuations in the surface speed of the conveyor belt. The positioning block 21 is fixedly connected to the slide table 22 by bolts. The fixing method is a multi-point fastening structure, which ensures that the positioning block 21 and the slide table 22 remain rigidly integrated throughout the entire transportation and welding process, without relative displacement. The positioning block 21 is a precision bearing block used to place and limit the upper and lower covers of the product. It is machined with a positioning structure that matches the contour of the product, so that the lower cover of the product can automatically fit into the set position area after placement, and at the same time provide an accurate reference for the subsequent bonding and welding of the upper cover of the product. By combining the mobility of the slide table 22 with the precise positioning function of the positioning block 21, the positioning component 2 can maintain the stable bearing mode of the product throughout the entire conveying path, so that the product's posture does not shift during the transfer process from the loading end to the welding station.

[0034] During equipment operation, the slide 22 moves forward continuously along with the belt conveyor 11, synchronously transporting the positioning block 21 and the product it carries to the welding station. When the slide 22 reaches the welding position of the limiting component 12, the limiting component 12 stops the slide 22 and then lifts it upward. At this time, since the positioning block 21 and the slide 22 are rigidly fixed, the position of the product above the positioning block 21 is simultaneously and accurately brought into the welding station, achieving spatial position locking before welding. Because the positioning block 21 has been pre-set with grooves, edge limiting, or contour fitting structures according to the product size and shape during processing, the lower cover of the product can be firmly attached to the positioning block 21 throughout the entire conveying process, avoiding positional drift under vibration or acceleration changes. When the clamping mechanism 6 places the upper cover of the product, the limiting structure of the positioning block 21 can also effectively guide the upper cover of the product to fall quickly and prevent it from being eccentric or angularly incorrect, providing a good pre-alignment basis for the subsequent ultrasonic welding head 5 pressing down and welding. Thus, through the structural design of the slide table 22 being responsible for movement and the positioning block 21 being responsible for precise bearing and limiting, the positioning component 2 has both transmission and positioning functions, realizing stable connection of the product in the three stages of conveying, docking and welding, effectively reducing manual intervention in the process chain and improving welding consistency and production cycle.

[0035] Furthermore, the positioning block 21 is provided with a positioning groove 211 and a positioning boss 212 at intervals. The positioning groove 211 is positioned and engaged with the lower cover of the product, and the positioning boss 212 is positioned and engaged with the upper cover of the product. The clamping mechanism 6 is located on the side of the belt conveyor 11 near the positioning boss 212.

[0036] In this embodiment, the upper surface of the positioning block 21 is provided with positioning grooves 211 and positioning bosses 212 at intervals according to the product structural features. The two form a set of mutually cooperating reference positioning structures in the planar position and height direction. The positioning grooves 211 are recessed in the upper surface of the positioning block 21, and their outline dimensions match the bottom shape of the product cover or a specific support area. When the product cover is placed on the positioning block 21, the product cover will automatically fall into the positioning groove 211 under the action of gravity and operation guidance. The bottom and wall of the groove limit it in three directions, thereby forming effective constraints in the front-back direction, left-right direction and some rotational degrees of freedom, ensuring that the product cover always maintains the set posture during the conveying with the slide table 22 and subsequent welding process. The positioning boss 212 is set on the upper surface of the positioning block 21 in a raised form. Its planar contour corresponds to the mating structure or inner cavity contour of the product cover. When the clamping mechanism 6 sends the product cover above the positioning block 21 and slowly lowers it, the inner cavity of the product cover will engage with the positioning boss 212 in a guiding manner. Under the combined action of gravity and the release action of the clamp, the product cover gradually slides down and is fitted onto the positioning boss 212, thereby obtaining positioning constraints in the horizontal and rotational directions, so that the product cover and the product bottom cover naturally form a preset coaxial relationship and covering relationship.

[0037] The clamping mechanism 6 is arranged on the side of the belt conveyor 11 near the positioning boss 212, with its extension arm facing the area above the positioning block 21. With this arrangement, after picking up the product cover from the loading station, the clamping mechanism 6 only needs to translate and appropriately raise and lower along the direction near the positioning boss 212 to accurately deliver the product cover above the positioning boss 212, reducing unnecessary lateral travel and minimizing positional errors and vibration effects caused by long travel. During actual operation, the positioning groove 211 provides stable reference support for the product cover, keeping it stationary throughout the positioning, placement, and welding stages. The positioning boss 212 provides a precise guide center for the product cover. The clamping mechanism 6 only needs to move the product cover above the capture area of ​​the positioning boss 212, and after the release action, the positioning boss 212 automatically completes the final precise positioning. In this way, the positioning groove 211, the positioning boss 212, and the clamping mechanism 6 form an organic linkage in terms of spatial position and function: the positioning groove 211 fixes the lower cover of the product on the positioning block 21, the positioning boss 212 guides and limits the placement posture of the upper cover of the product, and the clamping mechanism 6 completes the transportation and placement of the upper cover by taking a short path close to the positioning boss 212. The three work together to enable the upper cover and the lower cover of the product to achieve a high-precision alignment state before welding, providing a reliable, stable and repeatable assembly foundation for the subsequent pressing welding of the ultrasonic welding head 5, thereby significantly improving the welding quality and the consistency of the production cycle.

[0038] Specifically, when the position detection component 4 detects, it will raise the limiting end of the limiting component 2 first according to the preset time difference. The preset time difference will make the raising of the limiting end less abrupt, so that the limiting end of the limiting component 2 can more stably block the positioning component 2.

[0039] Furthermore, a pressing component 3 is provided on one side of the belt conveyor 11. When the positioning component 2 disengages from the belt conveyor 11, the pressing surface of the pressing component 3 presses down to abut against the slide table 22, thereby positioning and stabilizing the slide table 22.

[0040] In this embodiment, a clamping assembly 3 is provided on one side of the belt conveyor 11. The clamping assembly 3 is structurally positioned adjacent to the lateral area of ​​the slide table 22, allowing it to intervene promptly after the positioning component 2 is lifted off the belt conveyor 11 by the limiting component 12, applying a downward stabilizing clamping force to the slide table 22. Since the slide table 22 loses its support from the belt conveyor 11 after being lifted by the limiting component 12, without additional posture constraints, it may sway laterally, flip upwards, or slightly displace during the welding stage due to equipment vibration, instantaneous force generated by the welding head pressing down, or minor disturbances caused by the movement of the clamping mechanism 6. This could affect the alignment accuracy of the product on the positioning block 21 and the consistency of the welding head pressing. Therefore, the clamping assembly 3 is structurally positioned to the side of the belt conveyor 11, allowing it to apply a vertical or oblique clamping force to the upper surface or side of the slide table 22 the instant it is lifted into position, maintaining the slide table 22 in a rigid locked state during the welding process.

[0041] Specifically, after the positioning component 2 moves to the welding station with the belt conveyor component 11, the limiting component 12 lifts the slide table 22 away from the conveying surface of the belt conveyor component 11 through an upward action, causing the slide table 22 to enter a suspended state. After the slide table 22 completes the lifting action, the pressing surface of the clamping component 3 immediately descends from above and fits against the upper surface of the slide table 22, forming a fixed constraint through mechanical pressing. This ensures that the posture of the slide table 22 no longer depends on the belt conveyor component 11, but is maintained by the clamping structure jointly constructed by the clamping component 3 and the limiting component 12. This clamping state not only provides stable support in the vertical direction, but also suppresses the slight tilting and slight displacement of the slide table 22 through the contact area and friction of the pressing surface, ensuring that the product carried on the positioning block 21 maintains a strictly consistent spatial position. In addition, the lateral arrangement of the clamping component 3 and the belt conveyor component 11 ensures that they do not interfere with the vertical movement path of the positioning component 2 during operation, nor do they affect the product cover placement action of the clamping mechanism 6, thus maintaining coordination with the working rhythm of the entire device.

[0042] Furthermore, the pressing assembly 3 includes a first lifting cylinder and a right-angle pressure plate 31. The driving end of the first lifting cylinder is connected to one end of the right-angle pressure plate 31 to drive the right-angle pressure plate 31 to lift. The other end of the right-angle pressure plate 31 is parallel to the side of the slide table 22 connected to the positioning block 21 to fit the slide table 22 for positioning and stabilization.

[0043] In this embodiment, the clamping assembly 3 adopts a controllable clamping structure consisting of a first lifting cylinder and a right-angle pressure plate 31. The first lifting cylinder serves as the power actuator for the entire clamping assembly 3, and its drive end is rigidly connected to one end of the right-angle pressure plate 31 via a screw or connecting seat. This allows the piston rod of the first lifting cylinder to directly drive the right-angle pressure plate 31 to move vertically up and down during its extension and retraction. Structurally, the first lifting cylinder is fixed to the lateral base of the device frame or belt conveyor 11, with its direction of motion vertically aligned with the upper area of ​​the slide table 22, ensuring that the right-angle pressure plate 31 accurately contacts the designated force-bearing surface of the slide table 22 when it is pressed down. The other end of the right-angle pressure plate 31 extends along the length direction, and its pressing surface is strictly parallel to the lateral plane of the positioning block 21 connected on the slide table 22. This allows the right-angle pressure plate 31 to press the slide table 22 in a large-area fit when it is pressed down, thereby avoiding local indentations or uneven force that may be caused by point contact, and enabling the slide table 22 to obtain more stable posture constraints during welding.

[0044] The first lifting cylinder begins to operate after the positioning component 2 is lifted off the belt conveyor component 11 by the limiting component 12. Its piston rod extends downward, driving the right-angle pressure plate 31 closer to the slide table 22. After the pressing surface of the right-angle pressure plate 31 contacts the slide table 22, the first lifting cylinder continues to apply stable downward pressure, so that the slide table 22 obtains reliable, continuous and controllable clamping force in the vertical direction, further enhancing the fixation of the slide table 22 relative to the whole machine during the welding process. Since the pressing surface of the right-angle pressure plate 31 is parallel and in contact with the side of the positioning block 21 connected to the slide table 22, when the right-angle pressure plate 31 is pressed down into place, it can not only limit the upward floating of the slide table 22 in the vertical direction, but also effectively suppress the slight forward or backward displacement or lateral shift that the slide table 22 may produce through the contact friction, thereby keeping the product position carried on the positioning block 21 in accurate three-dimensional spatial coordinates throughout the welding process.

[0045] Furthermore, the other end of the right-angle pressure plate 31 is provided with two spaced pressure strips 32, one end of which is integrally connected to each other. The gap width between the two pressure strips 32 is greater than the width of the positioning block 21, so as to make room for the positioning block 21 and make the pressure strip 32 fit against the positioning block 21, thereby cooperating to position and stabilize the slide table 22.

[0046] In this embodiment, two spaced-apart pressure strips 32 are provided on the other end of the right-angle pressure plate 31. The two pressure strips 32 are integrally connected at one end to form an integral load-bearing component, which has a "gate-shaped" cross-connection structure, so that it can stably hold the positioning component 2 without interfering with the positioning block 21. The gap width of the pressure strips 32 is designed to be greater than the width of the positioning block 21, so that after the positioning block 21 is lifted off the belt conveyor component 11 by the limiting component 12, it can smoothly enter the clearance area between the two pressure strips 32 during the rising process. Since the positioning block 21 will not collide with the pressure strips 32, the entire lifting process remains smooth and there will be no jamming or deflection due to structural interference. When the right-angle pressure plate 31 is driven downward by the first lifting cylinder, the pressure strip 32 at its end will descend and pass over the slide table 22, eventually reaching the pressing position that is close to both sides of the positioning block 21. Since the inner sides of the two pressure strips 32 and the outer contour of the positioning block 21 are designed to fit together, after being pressed down, the contact between the pressure strips 32 and the positioning block 21 forms a double-sided limit, so that the positioning block 21 obtains a clear limit constraint in the lateral direction, avoiding micro-displacement in the horizontal direction during the welding process.

[0047] The double-sided contact of the pressure strip 32 not only enhances the stability of the slide table 22 and the positioning block 21 within the welding station, but also forms symmetrical pressure in the left and right directions through the double-point pressing structure. This prevents the slide table 22 from rotating or tilting under stress, thus maintaining the product cover and the product bottom cover in a strictly consistent three-dimensional posture at the moment of welding. In addition, the spaced arrangement of the pressure strip 32 ensures that the pressure plate assembly does not obstruct the area above the positioning block 21 while it is in contact with it. Therefore, the clamping mechanism 6 still has sufficient working space when performing the action of placing the product cover, ensuring that the product cover can be smoothly placed onto the positioning boss 212 from the vertical direction without interfering with the pressing structure. The combination of right-angle pressure plate 31, pressure strip 32, slide table 22, and positioning block 21 enables the clamping action to firmly lock the positioning component 2 during welding by pressing on both sides without affecting the product placement path. This improves the alignment consistency and pressing stability when the welding head is pressed down, ultimately making the welding quality more reliable and the equipment operation cycle more stable.

[0048] Furthermore, the belt conveyor 11 is provided with a position sensing component 4 electrically connected to the limiting component 12. The detection area of ​​the position sensing component 4 covers the welding station to detect whether the positioning component 2 is located at the welding station.

[0049] In this embodiment, the belt conveyor 11 is equipped with a position sensing component 4 electrically connected to the limiting component 12. The position of the position sensing component 4 is precisely calibrated so that its detection area can completely cover the welding station formed between the ultrasonic welding head 5 and the limiting component 12. The position sensing component 4 serves as the trigger condition detection unit for the entire automatic welding cycle. Its function is to determine in real time whether the positioning component 2 has accurately entered the predetermined welding area through non-contact detection as the positioning component 2 arrives at the welding station with the slide table 22. When the positioning component 2 is conveyed to the bottom of the welding station and enters the detection range of the position sensing component 4, the position sensing component 4 will transmit the detection signal to the limiting component 12 or the upper control system in an electrical manner, so that the limiting component 12 will immediately perform a stop and lifting action. At the same time, the clamping mechanism 6 and the ultrasonic welding head 5 also enter the next stage action queue synchronously according to the arrival signal of the position sensing component 4, realizing continuous process control of product cover clamping, cover placement, and welding head pressing.

[0050] The electrical connection of the position sensing component 4 enables it to form a closed-loop control logic with the limiting component 12. This means the position of the positioning component 2 is monitored in real time, and the limiting action is triggered immediately based on the actual monitoring results. This makes the lifting timing of the positioning component 2 by the limiting component 12 more precise, avoiding premature lifting that could cause the slide table 22 to deviate, and also avoiding delayed lifting that could cause the positioning component 2 to overshoot the workstation. The detection area of ​​the position sensing component 4 covers the entire welding station, making it unaffected by product model, the size of the positioning block 21, or slight differences in the position of the slide table 22. This ensures consistent triggering conditions for different batches and different cycle times. Through this layout, this embodiment ensures more precise cycle control of the welding station, improves the coordination of automated actions, and achieves strict synchronization between conveying, limiting, cover placement, and welding actions, ultimately improving welding quality and equipment operational stability.

[0051] Furthermore, the position sensing component 4 includes a connecting block 41, a vertical rod 42, and a sensing probe 43. The connecting block 41 is detachably connected to the belt conveyor component 11. The vertical rod 42 is inserted into the connecting block 41, and the sensing probe 43 is located at the end of the vertical rod 42 near the ultrasonic welding head 5.

[0052] In this embodiment, the position sensing component 4 consists of a connecting block 41, a vertical rod 42, and a sensing probe 43. These three components are combined in an adjustable mounting structure, allowing the position sensing component 4 to be flexibly arranged according to the actual height of the welding station, the movement trajectory of the slide table 22, and the working space of the ultrasonic welding head 5. The connecting block 41 is detachably fixed to the lateral mounting position of the belt conveyor component 11, forming a reliable connection with the belt conveyor component 11 via screws, clips, or a quick-release structure. It can be quickly disassembled and reinstalled when maintenance or position adjustment is required. The upper end of the connecting block 41 is provided with a mounting hole or guide groove. The vertical rod 42 is inserted into the structural hole of the connecting block 41. The vertical rod 42 can be finely adjusted along the vertical direction or within a small angular range, thereby allowing the height and angle of the sensing probe 43 to accurately adapt to the vertical position of the positioning component 2 at the welding station.

[0053] The sensor probe 43 is installed at the end of the vertical rod 42 near the ultrasonic welding head 5, directly facing the welding station area. This allows it to accurately detect the positioning block 21 or slide table 22's positioning status when the positioning component 2 enters the welding position from the pre-conveying stage. The sensor probe 43 can use photoelectric, proximity, inductive, or miniature distance sensors. It outputs an electrical signal by detecting the positional characteristics of the positioning component 2. This signal is transmitted to the limiting component 12 and the upper control system via the wiring within the vertical rod 42 and connecting block 41. This ensures that the limiting action, cover placement action, and welding action of the entire equipment are triggered by the detection result of the sensor probe 43. Since the vertical rod 42 can be adjusted according to the product size or station height, the sensor probe 43 can maintain a stable detection position without interfering with the movement path of the ultrasonic welding head 5, thus achieving accurate and reliable positioning judgment.

[0054] Furthermore, the clamping mechanism 6 includes a lifting component 61, a translation component 62, and a clamping component 63. The lifting component 61 is connected to the translation component 62 to drive the translation component 61 to move towards or away from the positioning component 2. The translation component 61 is connected to the clamping component 63 to drive the clamping component 63 to move along both sides of the belt conveyor component 11. The clamping component 63 is used to clamp the product cover placed on the positioning component 2.

[0055] In this embodiment, the clamping mechanism 6 consists of a lifting component 61, a translation component 62, and a clamping component 63, which are connected in series. This allows the clamping mechanism 6 to achieve three-dimensional motion combinations in the vertical, left-right, and clamping directions, thereby completing the picking, handling, and precise placement of the product cover along the conveying path. The lifting component 61 is located at the outermost support position of the clamping mechanism 6, and its lower end is rigidly connected to the translation component 62, allowing the translation component 62 to rise or fall as a whole under the drive of the lifting component 61 to adapt to changes in the product cover picking and placement height. During equipment operation, the lifting component 61 can controllably stroke to precisely position the clamping mechanism 6 in the vertical direction according to the actual height of the slide table 22, the position of the positioning block 21, and the space requirements of the welding area. This ensures that the clamping component 63 will not collide with the product during operation, nor will it interfere with the working area of ​​the ultrasonic welding head 5.

[0056] The translation component 62 is installed at the lower end of the lifting component 61 and moves towards or away from the positioning component 2 via a linear guide, slide bar, or cylinder structure. After the lifting component 61 raises the entire clamping mechanism 6 to a suitable height, the translation component 62 moves laterally to position the clamping component 63 directly above or near the location of the product cover, allowing the clamping component 63 to perform a clamping action. Similarly, during the placement phase, the translation component 62 can move the clamping component 63 above the positioning block 21, ensuring the product cover is precisely placed within the guide range of the positioning boss 212, thus achieving stable positioning. The lateral movement path of the translation component 62 is optimized so that its range of motion covers the loading position of the product cover without structural interference with the belt conveyor component 11, the limiting component 12, or the clamping component 3.

[0057] The gripping component 63, as the actuator that directly contacts the product, is installed at the front end of the translation component 62. Its structure includes grippers, a gripping drive mechanism, and a buffer fitting component. The gripping component 63 automatically clamps the product cover when it approaches via the gripper mechanism and maintains a stable grip during the lateral movement of the translation component 62. When the gripping component 63 is moved above the positioning block 21, the lifting component 61 controls the gripping component 63 to move downwards, causing the product cover to gradually fall into the guide range of the positioning boss 212. At an appropriate height, the grippers release, allowing the product cover to form a precise fit with the product bottom cover under the guidance of gravity and the limiting position of the positioning boss 212. The entire gripping action is highly automated through the coordinated action of these three components, not only improving the repeatability of the cover placement but also avoiding the problems of misalignment, tilting, or damage that may occur with manual cover placement.
