Description

Technical Field

[0001] This invention belongs to the field of new energy battery technology, and specifically relates to an automatic hot melt machine. Background Technology

[0002] When assembling the substrate and the lower cover, an ultrasonic hot melt machine is used to ultrasonically heat melt the substrate and the lower cover together. Ultrasonic hot melt can firmly fix the substrate and the lower cover together, preventing them from falling off or loosening during use. It forms a uniform and dense connection between the substrate and the lower cover, which can effectively prevent dust, moisture and other impurities from entering the assembly and improve the sealing performance of the product. In addition, ultrasonic hot melt can connect the substrate and the lower cover without the use of additional adhesives or glues, thereby reducing costs and production time. Ultrasonic hot melt can make the connection between the substrate and the lower cover look cleaner and more beautiful, improving the overall appearance quality of the product.

[0003] In traditional technology, the ultrasonic hot-melt process for assembling the substrate and lower cover often involves manual loading. On the one hand, manual loading is costly, as labor and training costs increase manufacturing costs. Manual loading requires repetitive operations, leading to high workload, fatigue, and errors, thus affecting efficiency and product quality. On the other hand, manual loading relies heavily on visual inspection of the substrate and lower cover, increasing the risk of missed or false positives, resulting in a high number of defective lower covers and impacting product quality and reliability. Furthermore, the manual loading process is susceptible to instability due to operator skill level and work status, affecting product consistency and stability. Summary of the Invention

[0004] To overcome the shortcomings of existing technologies and solve the problems of high cost, high labor intensity, difficult inspection and poor production stability caused by manual loading of substrates for assembling the lower cover in traditional technologies, this invention proposes an automatic hot melt machine.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] An automatic hot melt machine includes an automated conveyor line, on both sides of which are connected a docking production line and a customer discharge production line. On both sides of the automated conveyor line are respectively provided an assembly cover hot melt machine, and on the outside of the assembly cover hot melt machine is a cover feeding line for conveying the cover hopper.

[0007] The docking production line is a substrate unloading line at the upper station. The substrate is fed through the docking production line. The customer unloading production line is used to unload the finished product material after the bottom cover substrate is hot-melted. The bottom cover feeding line is used to feed the bottom cover. The bottom cover assembly hot-melt machine automatically picks up the substrate from the docking production line and the bottom cover from the bottom cover feeding line, and then automatically hot-melts the substrate and bottom cover. The assembly bottom cover hot-melt machine with dual stations on both sides of the automated conveyor line can greatly improve the efficiency of substrate bottom cover hot-melting and increase production efficiency.

[0008] The assembly platform of the bottom cover hot melt machine is equipped with a substrate gripping mechanism, a substrate buffer position, a barcode defective unloading line, a reverse defective substrate unloading position, a tooling transmission line, a barcode defective unloading and handling mechanism, a bottom cover gripping mechanism, a bottom cover secondary positioning platform, a reverse defective bottom cover unloading box, a substrate barcode scanning mechanism, an ultrasonic welding machine, an ultrasonic loading and unloading mechanism, an unloading assembly line, and a transfer mechanism.

[0009] The substrate gripping mechanism is used to grip the substrate on the docking production line and transfer the substrate to the tooling transmission line. The lower cover gripping mechanism is used to grip the lower cover on the lower cover feeding line and transfer the lower cover to the substrate conveyed by the tooling transmission line. The barcode defective unloading and handling mechanism is used to clamp and transfer the barcode defective products on the tooling transmission line to the barcode defective unloading line. The transfer mechanism is used to transfer the products on the unloading production line to the customer unloading production line.

[0010] The substrate gripping mechanism picks up the substrate from the docking production line. After the reverse detection sensor identifies the reverse, the good product at the identification point is rotated 90° and placed into the tooling transmission line. When the substrate is reversed and defective, it is placed into the substrate reversed and defective unloading position. When the equipment is briefly abnormal, the substrate gripping mechanism picks up the substrate and places it into the substrate buffer position. When the equipment is idle, it picks up the substrate from the buffer position and continues to work.

[0011] The lower cover gripping mechanism picks up the lower cover from the lower cover feeding line. A foolproof sensor is installed on the lower cover gripping mechanism to identify the correct orientation of the lower cover. Good products are placed on the lower cover secondary positioning platform, while defective products are placed in the lower cover reverse defective unloading box. The lower cover gripping mechanism then removes the lower cover from the secondary positioning platform and grips it onto the tooling transmission line for assembly into the substrate. The substrate is then conveyed by the tooling transmission line into the substrate scanning station, where it is scanned by the substrate scanning mechanism. Good products are then fed into the ultrasonic welding machine for heat melting via the ultrasonic loading and unloading mechanism. Defective products are picked up by the defective unloading and conveying mechanism and placed on the defective unloading line. The finished products processed by the ultrasonic welding machine are fed into the unloading line via the ultrasonic loading and unloading mechanism. Finished products at the unloading line's outlet are picked up by the transfer mechanism and transferred to the customer's unloading line.

[0012] Preferably, the docking production line is equipped with a positioning module and a positioning adjustment plate that cooperate with the substrate for positioning and limiting. After the substrate flows into the docking production line, it is positioned by the positioning module and the positioning adjustment plate, which facilitates the substrate gripping mechanism to accurately grip the substrate.

[0013] Preferably, a lower cover lifting mechanism is fixedly provided on one side of the machine tool to lift the lower cover in the lower cover hopper. The lower cover lifting mechanism includes a second lead screw linear module fixed on one side of the machine tool and a lower cover lifting block fixedly connected to a slide on the second lead screw linear module. The lower cover lifting block is driven by the action of the second lead screw linear module to lift the lower cover in the lower cover hopper through the through hole in the lower cover feeding line and the lower cover hopper, which can automatically feed the upper cover and facilitate the lower cover gripping mechanism to grip the lower cover on the lower cover feeding line.

[0014] Preferably, the substrate buffer position is provided with an adjustable hopper and a substrate buffer lifting mechanism for lifting the substrates in the adjustable hopper. The substrate buffer lifting mechanism includes a first lead screw linear module fixed below the machine tool and a substrate lifting block fixedly connected to a slide table on the first lead screw linear module. The first lead screw linear module drives the substrate lifting block to pass through the through holes in the machine tool and the adjustable hopper to lift the substrates in the adjustable hopper upwards, which facilitates the feeding of substrates in the substrate buffer position and facilitates the substrate gripping mechanism to grip the substrates in the substrate buffer position and place them into the tooling transmission line.

[0015] Preferably, the substrate gripping mechanism is equipped with a reverse detection sensor for identifying and detecting the reverse side of the substrate; the lower cover gripping mechanism is equipped with two lower cover anti-foolproof sensors for identifying the front and back sides.

[0016] The reverse detection sensor can identify the front and back of the substrate, ensuring that the substrate is correctly oriented during assembly. This avoids assembly deviations or poor assembly caused by incorrect substrate orientation, improving the accuracy and reliability of the assembly.

[0017] The bottom cover error sensor can identify the front and back of the bottom cover, preventing it from being assembled with the wrong orientation. This avoids defective products caused by incorrect bottom cover assembly onto the substrate, improving the accuracy and stability of product assembly.

[0018] Preferably, the defective barcode scanning unloading and handling mechanism includes a first rotary cylinder fixed on the machine base, a lifting cylinder mounted on the first rotary cylinder, and a gripper cylinder C mounted on the lifting cylinder. The defective barcode scanning products on the tooling transmission line are clamped and transferred to the defective barcode scanning unloading line through the cooperation of the first rotary cylinder, the lifting cylinder, and the gripper cylinder C.

[0019] When a defective product is detected during barcode scanning, the first rotary cylinder rotates the gripper cylinder C to above the defective product. The lifting cylinder then moves the gripper cylinder C down to grab the defective product, and then moves it up again. The first rotary cylinder rotates the gripper cylinder C to above the barcode defective unloading line, and the lifting cylinder moves the gripper cylinder C down to place the grabbed defective product onto the barcode defective unloading line.

[0020] Preferably, the substrate scanning mechanism includes two barcode scanners located on the upper and lower sides of the feed end of the tooling transmission line for scanning the lower cover of the assembled substrate.

[0021] Preferably, the ultrasonic welding machine's operating table is equipped with a welding lower mold and a first positioning cylinder and a second positioning cylinder for positioning the substrate and lower cover on the welding lower mold. When the first positioning cylinder and the second positioning cylinder are activated, they push the positioning plate connected to the piston rod on their upper part to position the substrate and lower cover on the welding lower mold, which facilitates the ultrasonic welding machine to perform heat fusion welding on the substrate and lower cover, resulting in accurate welding positioning and good welding quality.

[0022] Preferably, the ultrasonic loading and unloading mechanism includes an inverted U-shaped bracket fixed on the machine base, a transverse cylinder on the inverted U-shaped bracket, a first lifting module on the moving seat of the transverse cylinder, a support plate on the lifting slide of the first lifting module, a first mounting plate and a second mounting plate vertically arranged on both sides of the support plate, a first clamping assembly on the first mounting plate for transferring the product on the tooling transmission line outlet end to the welding lower mold, and a second clamping assembly on the second mounting plate for transferring the product on the welding lower mold to the unloading production line.

[0023] The first clamping assembly includes a gripper cylinder A fixed to the bottom of the first mounting plate and two limiting cylinders located on both sides of the gripper cylinder A. The piston rods of the two limiting cylinders are respectively connected to two limiting plates that limit the movement of the lower cover plate on both sides.

[0024] The second clamping assembly includes a gripper cylinder B rotatably disposed at the bottom of the second mounting plate, a first pulley connected to the fixed end of the gripper cylinder B and disposed above the second mounting plate, a 90° rotating cylinder fixed at the bottom of the second mounting plate, a second pulley disposed above the second mounting plate and connected to the 90° rotating cylinder, and a transmission belt sleeved on the outer sides of the first pulley and the second pulley.

[0025] The ultrasonic loading and unloading mechanism can send the scanned good products into the ultrasonic welding machine for hot melting operation. On the other hand, the finished products processed by hot melting are sent into the unloading production line through the ultrasonic loading and unloading mechanism.

[0026] When the ultrasonic loading and unloading mechanism is working, the lateral cylinder moves, causing the first lifting module, the first clamping assembly, and the second clamping assembly to move horizontally. The first clamping assembly moves above the scanned good product, and the second clamping assembly moves above the finished product from the hot melt process. Then, the first lifting module moves, causing the first and second clamping assemblies to move downwards. The first clamping assembly, through the coordinated action of its limiting cylinder and gripper cylinder A, moves the limiting plate to grip the lower cover plate from the left and right ends, and the gripper cylinder A moves the lower cover plate back and forth. The two-end gripper can stably grip the lower cover substrate. The second clamping component grips the finished material through the gripper cylinder B on it. The first lifting module, in conjunction with the transverse cylinder, drives the gripped lower cover substrate and finished material to move up, then horizontally, and finally down, transferring the gripped lower cover substrate to the welding mold of the ultrasonic welding machine. The 90° rotation cylinder drives the first pulley, the second pulley, and the transmission belt to rotate the gripper cylinder B 90°, rotating the gripped finished material 90° and placing it into the unloading production line.

[0027] Preferably, the transplanting mechanism includes two support columns fixed on the machine base, a horizontal transplanting module fixed on the two support columns, a second lifting module disposed on the slide of the horizontal transplanting module, a transplanting plate disposed on the lifting slide of the second lifting module, and a product suction cup disposed on the transplanting plate.

[0028] The horizontal transplanting module and the second lifting module on the transplanting mechanism move to drive the product suction cup to move horizontally and descend to pick up the finished material on the unloading line, and then move upward and horizontally to transfer the finished material to the customer's unloading line to complete the unloading of the finished material.

[0029] The technical effects and advantages of this invention are as follows:

[0030] The automated conveyor line, docking line, and customer unloading line on the automatic hot melt machine are used to transport the substrate and the lower cover, respectively, to ensure the smooth operation of the production line and to ensure efficient production and transfer of products during the production process. The lower cover assembly hot melt machine is used to automatically heat melt the substrate and the lower cover, which improves production efficiency. The lower cover feeding line is used to supply the lower cover to the lower cover assembly hot melt machine to ensure that the production line will not be interrupted due to the depletion of lower covers.

[0031] The automatic hot melt machine has a substrate gripping mechanism and a lower cover gripping mechanism for gripping the substrate and lower cover respectively and placing them in the appropriate positions for automated processing in subsequent production. The ultrasonic welding machine and the ultrasonic loading and unloading mechanism are used to perform ultrasonic hot melt on the assembled substrate and lower cover and produce finished products. The ultrasonic loading and unloading mechanism helps to transfer products and improve production efficiency.

[0032] This automatic hot melt machine uses a defective barcode scanning unloading line to handle product quality issues. A transfer mechanism helps move finished products from one location to another. These components and mechanisms work together to provide an efficient and automated production method, improving production efficiency, ensuring product quality, and reducing manual intervention.

[0067] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0068] The following is in conjunction with the appendix Figure 1-13 This application will be described in further detail;

[0069] This application discloses an automatic hot melt machine.

[0070] Reference Figure 1-4 An automatic hot melt machine includes an automated conveyor line 100, on which a docking assembly line 200 and a customer discharge assembly line 300 are connected on both sides. On both sides of the automated conveyor line 100, there are respectively a bottom cover assembly hot melt machine 400. On the outside of the bottom cover assembly hot melt machine 400, there is a bottom cover feeding line 500 for conveying the bottom cover hopper 51.

[0071] The docking production line 200 is a substrate unloading line at the upper station. The substrate is fed through the docking production line 200. The customer unloading production line 300 is used for unloading and conveying the finished product material after the lower cover substrate is hot-melted. The lower cover feeding line 500 is used for feeding the lower cover. The lower cover assembly hot-melt machine 400 automatically picks up the substrate from the docking production line 200 and the lower cover from the lower cover feeding line 500, and then automatically hot-melts the substrate and lower cover. The dual-station lower cover assembly hot-melt machine 400 set on both sides of the automated conveyor line 100 can greatly improve the substrate lower cover hot-melt efficiency and improve production efficiency.

[0072] Reference Figure 7-9 The assembly base 41 of the lower cover hot melt machine 400 is equipped with a substrate gripping mechanism 42, a substrate buffer position 43, a barcode defective unloading line 44, a reverse defective substrate unloading position 45, a tooling transmission line 46, a barcode defective unloading and conveying mechanism 47, a lower cover gripping mechanism 48, a lower cover secondary positioning platform 49, a reverse defective lower cover unloading box 410, a substrate barcode scanning mechanism 411, an ultrasonic welding machine 412, an ultrasonic loading and unloading mechanism 413, an unloading assembly line 414, and a transfer mechanism 415.

[0073] The substrate gripping mechanism 42 is used to grip the substrate on the docking production line 200 and transfer the substrate to the tooling transmission line 46. The lower cover gripping mechanism 48 is used to grip the lower cover on the lower cover feeding line 500 and transfer the lower cover to the substrate conveyed by the tooling transmission line 46. The barcode defective unloading and handling mechanism 47 is used to clamp and transfer the barcode defective products on the tooling transmission line 46 to the barcode defective unloading line 44. The transfer mechanism 415 is used to transfer the products on the unloading production line 414 to the customer unloading production line 300.

[0074] The substrate gripping mechanism 42 picks up the substrate from the docking production line 200. After the reverse detection sensor 4201 identifies the reverse, the good product at the identification point is rotated 90° and placed into the tooling transmission line 46. When the substrate is reversed and defective, it is placed into the substrate reversed and defective unloading position 45. When the equipment is briefly abnormal, the substrate gripping mechanism 42 picks up the substrate and places it into the substrate buffer position 43. When the equipment is idle, the substrate is picked up from the buffer position and the work continues.

[0075] The lower cover gripping mechanism 48 grips the lower cover on the lower cover feeding line 500. A lower cover error-proof sensor 4801 is installed on the lower cover gripping mechanism 48 to facilitate correct orientation and prevent error. Correctly identified good products are placed on the lower cover secondary positioning platform 49, while incorrectly identified defective products are placed on the lower cover reverse defect unloading box 410. The lower cover gripping mechanism 48 then removes the lower cover from the lower cover secondary positioning platform 49 and grips it onto the tooling transmission line 46 for assembly onto the substrate. Through the conveying of the tooling transmission line 46, the substrate flows into the substrate scanning process. The substrate is scanned by the substrate scanning mechanism 411. Good products are fed into the ultrasonic welding machine 412 for hot melting operation by the ultrasonic loading and unloading mechanism 413. Defective products are picked up by the defective unloading and handling mechanism 47 and unloaded by the defective unloading line 44. The finished products processed by the ultrasonic welding machine 412 are fed into the unloading line 414 by the ultrasonic loading and unloading mechanism 413. The finished products at the outlet of the unloading line 414 are picked up by the transfer mechanism 415 and transferred to the customer unloading line 300.

[0076] The substrate gripping mechanism 42 and the lower cover gripping mechanism 48 can automatically complete the gripping, identification, and assembly of substrates and lower covers at different stages, improving production efficiency. The reverse detection sensor 4201 and the lower cover error-proof sensor 4801 can identify the forward and reverse errors in real time, ensuring product quality. Defective products are automatically placed in the corresponding positions, preventing the mixing of good products and ensuring the purity of the production line. The equipment has autonomous identification, gripping, assembly, and conveying functions, reducing manual intervention and lowering labor costs. When the equipment experiences a brief malfunction, the substrate gripping mechanism 42 will place the substrate into the substrate buffer position 43, waiting for the equipment to return to normal before continuing to work. This helps reduce production downtime and improve equipment utilization. Each stage, such as the substrate scanning station, ultrasonic welding machine 412, and unloading assembly line 414, has clear operation and monitoring, making the production process more standardized and orderly. Through sensors and monitoring equipment set at different stages, the production status can be monitored in real time, facilitating management to schedule and optimize the production process. The integrated design reduces the equipment footprint and lowers investment costs. Meanwhile, the equipment operates stably, reducing maintenance and repair costs. Automated production lines reduce human error, improve resource utilization, and reduce waste in the production process.

[0077] Reference Figure 5 The docking production line 200 is equipped with a positioning module 21 and a positioning adjustment plate 22 that cooperate with the substrate for positioning. After the substrate flows into the docking production line 200, it is positioned by the positioning module 21 and the positioning adjustment plate 22, which facilitates the substrate gripping mechanism 42 to accurately grip the substrate.

[0078] Precise positioning of the substrate ensures its accurate and stable position on the production line, facilitating precise gripping of the substrate by the substrate gripping mechanism 42 and reducing errors during the gripping process. Precise positioning helps the substrate gripping mechanism 42 grip the substrate quickly and accurately, reducing gripping time and improving gripping efficiency. Precise positioning can also prevent misalignment or blockage of the substrate on the production line, ensuring the stability and continuity of the production line. Furthermore, precise positioning reduces human intervention during the substrate gripping process, minimizing the impact of human factors on production.

[0079] Reference Figure 4 , Figure 8The substrate buffer position 43 is provided with an adjustable hopper 4301 and a substrate buffer lifting mechanism 4302 for lifting the substrates in the adjustable hopper 4301. The substrate buffer lifting mechanism 4302 includes a first lead screw linear module 4303 fixed below the machine base 41 and a substrate lifting block 4304 fixedly connected to a slide table on the first lead screw linear module 4303. The first lead screw linear module 4303 drives the substrate lifting block 4304 through the through hole in the machine base 41 and the adjustable hopper 4301 to lift the substrates in the adjustable hopper 4301 upward, which facilitates the feeding of substrates on the substrate buffer position 43 and facilitates the substrate gripping mechanism 42 to grip the substrates on the substrate buffer position 43 and put them into the tooling transmission line 46.

[0080] Reference Figure 8 The substrate gripping mechanism 42 is equipped with a reverse detection sensor 4201 for identifying and reverse detecting the substrate.

[0081] The reverse detection sensor 4201 can identify the front and back of the substrate, ensuring that the substrate is correctly oriented during assembly. This avoids assembly deviations or poor assembly caused by incorrect substrate orientation, improving the accuracy and reliability of assembly.

[0082] Reference Figure 6 A lower cover lifting mechanism 52 is fixedly provided on one side of the machine base 41 to lift the lower cover in the lower cover hopper 51. The lower cover lifting mechanism 52 includes a second lead screw linear module 5201 fixed on one side of the machine base 41 and a lower cover lifting block 5202 fixedly connected to the slide table on the second lead screw linear module 5201. The lower cover lifting block 5202 is driven by the action of the second lead screw linear module 5201 to pass through the through hole on the lower cover feeding line 500 and the lower cover hopper 51 to lift the lower cover in the lower cover hopper 51 upward. This enables automated feeding of the upper cover and facilitates the lower cover gripping mechanism 48 to grip the lower cover on the lower cover feeding line 500.

[0083] Reference Figure 9 The lower cover gripping mechanism 48 is equipped with two lower cover error-proof sensors 4801 to identify the front and back of the lower cover and prevent incorrect assembly. These sensors 4801 can identify the front and back of the lower cover, preventing incorrect orientation during assembly. This avoids defective products caused by incorrect lower cover assembly onto the substrate, improving the accuracy and stability of product assembly.

[0084] Reference Figure 10The defective barcode unloading and conveying mechanism 47 includes a first rotary cylinder 4701 fixed on the machine base 41, a lifting cylinder 4702 provided on the first rotary cylinder 4701, and a gripper cylinder C4703 provided on the lifting cylinder 4702. The defective barcode products on the tooling transmission line 46 are clamped and transferred to the defective barcode unloading line 44 through the cooperation of the first rotary cylinder 4701, the lifting cylinder 4702 and the gripper cylinder C4703.

[0085] When a defective product is detected during barcode scanning, the first rotary cylinder 4701 rotates the gripper cylinder C4703 to above the defective product. The lifting cylinder 4702 then moves the gripper cylinder C4703 down to grab the defective product, and then moves it up. The first rotary cylinder 4701 rotates the gripper cylinder C4703 to above the barcode defective unloading line 44, and the lifting cylinder 4702 moves the gripper cylinder C4703 down to place the grabbed defective product onto the barcode defective unloading line 44.

[0086] Driven by cylinders, automated transfer and handling are achieved, improving production efficiency. Through the coordination of rotary cylinders, lifting cylinders 4702, and gripper cylinders C4703, defective products can be easily transferred from the tooling transmission line 46 to the defective product unloading line 44, reducing manual intervention and operational complexity. When a defective product is detected during scanning, the mechanism can quickly grab it and place it on the defective product unloading line 44, ensuring smooth production line operation. The first rotary cylinder 4701, fixed on the machine base 41, improves the stability of the entire mechanism, reducing failure rate and maintenance costs. During operation, defective products are immediately placed on the defective product unloading line 44 after being grabbed, reducing the dwell time of defective products on the production line and minimizing safety risks. The mechanism has a compact structure, small footprint, and is easy to lay out and install. Automated handling reduces labor costs and production losses caused by human error. Timely identification and handling of defective products reduces the probability of them entering the next process, thereby improving overall product quality.

[0087] Reference Figure 7-9 The substrate scanning mechanism 411 includes two barcode scanners located on the upper and lower sides of the discharge end of the tooling transmission line 46 for scanning the assembled substrate bottom cover. By simultaneously scanning the substrate and bottom cover with two barcode scanners, scanning efficiency is improved, scanning waiting time is reduced, and all products are scanned in a timely manner. Dual scanning increases the system's product identification accuracy, reduces the possibility of missed scans and misidentification, and ensures the correctness of each product. Using multiple barcode scanners ensures consistency and accuracy in the scanning process. The dual barcode scanner design improves the speed and accuracy of product scanning, contributing to increased production line efficiency and data acquisition accuracy.

[0088] Reference Figure 11 The ultrasonic welding machine 412 has a welding lower mold 4121 and a first positioning cylinder 4122 and a second positioning cylinder 4123 on the operating table for positioning the substrate and lower cover on the welding lower mold 4121. When the first positioning cylinder 4122 and the second positioning cylinder 4123 are activated, they push the positioning plate connected to the piston rod on them to position the substrate and lower cover on the welding lower mold 4121, which facilitates the ultrasonic welding machine 412 to perform hot melt welding on the substrate and lower cover. The welding positioning is accurate and the welding quality is good.

[0089] The positioning cylinder precisely positions the substrate and the lower cover, ensuring that they maintain the correct relative position throughout the welding process, thereby improving welding accuracy. The positioning cylinder makes the welding of the substrate and the lower cover more stable, avoiding problems such as weak welding or uneven welds caused by positional deviation, thus improving welding quality. The precise positioning system can reduce the time wasted on adjusting the position during the welding process, improving production efficiency. The positioning of the substrate and the lower cover can be easily achieved through cylinder control on the operating table, making the welding process simpler.

[0090] Reference Figure 12 The ultrasonic loading and unloading mechanism 413 includes an inverted U-shaped bracket 4131 fixed on the machine base 41, a transverse cylinder 4132 on the inverted U-shaped bracket 4131, a first lifting module 4133 on the moving seat of the transverse cylinder 4132, a support plate 4134 on the lifting slide of the first lifting module 4133, a first mounting plate 4135 and a second mounting plate 4136 vertically arranged on both sides of the support plate 4134, a first clamping assembly 4137 on the first mounting plate 4135 for transferring the product on the discharge end of the tooling transmission line 46 to the welding lower mold 4121, and a second clamping assembly 4138 on the second mounting plate 4136 for transferring the product on the welding lower mold 4121 to the unloading assembly line 414.

[0091] The first clamping assembly 4137 includes a gripper cylinder A41371 fixed to the bottom of the first mounting plate 4135 and two limiting cylinders 41372 located on both sides of the gripper cylinder A41371. The piston rods of the two limiting cylinders 41372 are respectively connected to two limiting plates 41373 that limit the sides of the lower cover plate.

[0092] The second clamping assembly 4138 includes a gripper cylinder B41381 rotatably disposed at the bottom of the second mounting plate 4136, a first pulley 41382 connected to the fixed end of the gripper cylinder B41381 and disposed above the second mounting plate 4136, a 90° rotating cylinder 41383 fixed at the bottom of the second mounting plate 4136, a second pulley 41384 disposed above the second mounting plate 4136 and connected to the 90° rotating cylinder 41383, and a transmission belt sleeved on the outer sides of the first pulley 41382 and the second pulley 41384.

[0093] The ultrasonic loading and unloading mechanism 413 can send the scanned good products into the ultrasonic welding machine 412 for hot melting operation. On the other hand, the finished products processed by hot melting are sent into the unloading production line 414 through the ultrasonic loading and unloading mechanism 413.

[0094] When the ultrasonic loading and unloading mechanism 413 is working, the transverse cylinder 4132 moves, driving the first lifting module 4133, the first clamping assembly 4137, and the second clamping assembly 4138 to move horizontally. The first clamping assembly 4137 moves above the scanned good product, and the second clamping assembly 4138 moves above the finished product processed by hot melt. Then, the first lifting module 4133 moves, driving the first clamping assembly 4137 and the second clamping assembly 4138 to move downward. The first clamping assembly 4137, through the cooperation of the limiting cylinder 41372 and the gripper cylinder A41371, moves the limiting plate 41373 to grip the lower cover plate from the left and right ends. The first clamping assembly 4138 grips the front and rear ends of the lower cover substrate, enabling stable gripping of the lower cover substrate. The second clamping assembly 4138 grips the finished material via the gripper cylinder B41381. The first lifting module 4133, in conjunction with the transverse cylinder 4132, moves the gripped lower cover substrate and finished material upward, then horizontally, and finally downward, transferring the gripped lower cover substrate to the welding mold 4121 of the ultrasonic welding machine 412. The 90° rotation cylinder 41383 moves, driving the first pulley 41382, the second pulley 41384, and the transmission belt to rotate the gripper cylinder B41381 90°, rotating the gripped finished material 90° and placing it into the unloading line 414 for unloading.

[0095] The ultrasonic loading and unloading mechanism 413 can simultaneously complete the hot-melt processing of good products and the unloading of finished products, improving production efficiency. It adopts cylinder and pulley drive to realize automated transmission and gripping, reducing the intensity of manual labor. The precise control of the transverse cylinder 4132 and the lifting module ensures the stable transmission and gripping of good and finished products. The safety of the operation process is ensured by the coordinated action of the limit air and the gripper cylinder. The modular design makes it easy to disassemble and maintain. The structure is compact and occupies a small area. Through automated loading and unloading, production costs are reduced.

[0096] Reference Figure 13 The transplanting mechanism 415 includes two support columns 4151 fixed on the machine base 41, a horizontal transplanting module 4152 fixed on the two support columns 4151, a second lifting module 4153 provided on the slide of the horizontal transplanting module 4152, a transplanting plate 4154 provided on the lifting slide of the second lifting module 4153, and a product suction cup 4155 provided on the transplanting plate 4154.

[0097] The horizontal transplanting module 4152 and the second lifting module 4153 on the transplanting mechanism 415 move to drive the product suction cup 4155 to move horizontally and descend to pick up the finished material on the unloading line 414, and then move upward and horizontally to transfer the finished material to the customer unloading line 300 to complete the unloading of the finished material.

[0098] Through the coordinated operation of the horizontal transfer module 4152 and the second lifting module 4153, finished materials are quickly and accurately transferred from the unloading line 414 to the customer unloading line 300, reducing the production cycle and improving production efficiency. This automated transfer mechanism 415 can replace traditional manual handling, reducing the company's investment in manpower and saving costs. Through the precise control of the robotic arm, the stability and safety of the finished materials during the transfer process are ensured, avoiding problems such as damage and contamination that may occur during manual operation, thus improving product quality. After adopting the automated transfer mechanism 415, workers do not need to carry out handling work, reducing labor intensity and helping employees maintain a good working condition. This transfer mechanism 415 can achieve continuous operation, with high equipment utilization, which is conducive to improving the operating efficiency of the entire production line. During the transfer process, the contact between the finished materials and workers is reduced, reducing the risk of accidents and improving production safety.

[0099] The workflow of this automatic hot melt machine is roughly as follows:

[0100] 1. The substrate enters the automated conveyor line 100 through the docking production line 200, and is then picked up by the assembly cover hot melt machine 400 and placed on the tooling transmission line 46.

[0101] 2. The lower cover enters the lower cover assembly hot melt machine 400 through the lower cover feeding line 500, and is then picked up by the lower cover gripping mechanism 48 and placed on the tooling transmission line 46.

[0102] 3. The substrate and the lower cover enter the substrate scanning mechanism 411 for scanning via the tooling transmission line 46, and then enter the ultrasonic welding machine 412 for hot melting operation.

[0103] 4. After hot melting, the product enters the unloading production line 414 through the ultrasonic loading and unloading mechanism 413.

[0104] 5. If the product fails to scan the barcode, it will be picked up by the barcode failure unloading and handling mechanism 47 and placed on the barcode failure unloading line 44.

[0105] 6. The unloading line 414 delivers the finished material to the transfer mechanism 415, and then the transfer mechanism 415 transfers the finished material to the customer unloading line 300.

[0106] 7. After completing the transplanting, the transplanting mechanism 415 returns to its initial position, awaiting the arrival of the next batch of finished materials.

[0107] The above process is repeated cyclically to achieve automated production.

[0108] The application of automated conveyor line 100, docking assembly line 200, and customer unloading assembly line 300 enables automated conveying of substrates and bottom covers, as well as automated unloading of finished materials, reducing manual intervention and improving production efficiency. The dual-station assembly bottom cover hot-melt machine 400 significantly improves the hot-melt efficiency of substrates and bottom covers, thereby increasing overall production efficiency and achieving fast and efficient production. By automatically picking up substrates from the docking assembly line 200 and bottom covers from the bottom cover feeding line 500, and then automatically hot-melting the substrates and bottom covers, the quality and consistency of each assembled product can be ensured. The automated production process reduces manual operation, lowers labor costs, and improves production efficiency, thereby effectively saving production costs.

[0109] In conclusion, this automatic hot melt machine can improve production efficiency, enhance product quality, and save costs, thus possessing significant application value.
