Description

Technical Field

[0001] This application relates to the field of power supply production technology, and in particular to a dispensing and spraying mechanism and its operation method. Background Technology

[0002] In power supply manufacturing, dispensing and spraying are two key adhesive application processes, primarily used to achieve functions such as component fixation, insulation, sealing, or heat dissipation. In existing power supply manufacturing processes, dispensing is performed first using a dispensing machine, followed by spraying using a spraying machine; these are performed step-by-step on different equipment.

[0003] In the existing technology, after the power circuit board is glued on the dispensing machine, it is then transferred to the spraying machine for spraying. The flow between processes leads to low production efficiency. Furthermore, for single-function dispensing or spraying machines, a single nozzle is often used for assembly line operation, and each action can usually only process one product, which also leads to low production efficiency.

[0004] Therefore, existing technologies still need to be improved and developed. Summary of the Invention

[0005] In view of the shortcomings of the prior art, the purpose of this application is to provide a dispensing and spraying mechanism and operation method to solve the problem of low production efficiency caused by using a dispensing machine and a spraying machine to perform power processing separately in the prior art.

[0010] The adjustment drive assembly is disposed on the frame and connected to the sliding bracket. The sliding bracket is driven by the adjustment drive assembly to synchronously adjust a first distance and a second distance, wherein the first distance is the distance between the first adhesive dot and the second adhesive dot, and the second distance is the distance between the first sprayed part and the second sprayed part.

[0011] Optionally, the positioning drive assembly includes: a linear drive unit disposed along the length direction on the frame, and a sliding bracket disposed at the output end of the linear drive unit;

[0012] The power unit is connected to the linear drive unit to provide power for the movement of the output end of the linear drive unit.

[0013] Optionally, the linear drive unit includes: a lead screw, the two ends of which are rotatably connected to one side of the frame via bearing seats;

[0014] Nut connecting block, the nut connecting block is screwed to the lead screw, and the sliding bracket is fixed to the nut connecting block.

[0015] Optionally, a first guide assembly is provided on the frame. The first guide assembly and the linear drive unit are located on the same side of the frame and connected to the sliding bracket to guide the sliding bracket to slide along the length direction.

[0016] The frame is also equipped with a second guide component, which is located on the other side of the frame and connected to the sliding bracket.

[0017] Optionally, the power unit includes an adjustment knob, which is turned to drive the output end of the linear drive unit to slide along the length direction.

[0018] Optionally, the frame is provided with a measuring scale that extends a predetermined length along the length direction and is used to indicate the length value of a first distance or a second distance.

[0019] Optionally, the sliding bracket includes: a sliding spray pad, which is slidably disposed on one side of the bracket and connected to the second spraying component;

[0020] A sliding adhesive pad is slidably mounted on the other side of the frame and connected to a second adhesive component;

[0021] A sliding connecting plate extends along the width direction and is connected at both ends to a sliding spraying pad and a sliding dispensing pad, respectively.

[0022] One of the sliding spray pad and the sliding dispensing pad is connected to the positioning drive assembly.

[0023] Optionally, the first dispensing component is connected to the frame by a fixed dispensing pad block so that the dispensing port of the first dispensing component coincides with the dispensing port of the second dispensing component in the width direction.

[0024] The first sprayed part is connected to the frame by a fixed spraying pad so that the dispensing nozzle of the first sprayed part coincides with the dispensing nozzle of the second sprayed part in the width direction.

[0025] Optionally, the sliding bracket is provided with a locking component, which is used to generate friction between the sliding bracket and the frame to lock the sliding bracket.

[0026] Optionally, a first synchronous detection component is provided between the first and second adhesive application components, and a second synchronous detection component is provided between the first and second sprayed components. The deviation between the first and second distances is detected by comparing the measured values ​​between the first and second synchronous detection components.

[0027] On the other hand, this application also proposes a dispensing and spraying operation method, wherein the dispensing and spraying operation method is applied to the above-mentioned dispensing and spraying mechanism and includes the following steps:

[0028] Receive the sensor's sensing signal to determine that the fixture carrying the product has reached the predetermined work position, wherein the receiving of the sensor's sensing signal reaches a predetermined time.

[0029] Control the first and second adhesive dispensing components to move synchronously to the predetermined dispensing positions;

[0030] The first and second dispensing components are controlled to perform dispensing operations based on a preset path. If the dispensing time exceeds a preset threshold during the dispensing process, the first and second dispensing components are controlled to close and an alarm is triggered.

[0031] Once the first and second dispensing components are detected to have completed dispensing, the first and second dispensing components are controlled to rise back to their initial dispensing positions, while the first and second spraying components are controlled to descend to their predetermined spraying positions.

[0032] The first and second spraying parts are controlled to perform spraying operations based on a preset path. If the spraying time exceeds a preset threshold during the spraying process, the first and second spraying parts are controlled to shut down and an alarm is triggered.

[0033] Once the first and second sprayed parts are detected to have completed spraying, the first and second sprayed parts are controlled to rise back to the initial spraying position.

[0034] The dispensing and spraying mechanism is controlled to move to the machine origin, while the equipment conveyor track is controlled to allow the finished product to flow out of the predetermined operation position.

[0035] The beneficial effects of the dispensing and spraying mechanism and operating method provided in this application are at least as follows: By fixing a first dispensing component and a first spraying component to a frame, and additionally setting a second dispensing component and a second spraying component that are movable in position on the frame, the distance between the first and second dispensing components is a first distance, and the distance between the first and second spraying components is a second distance. The second dispensing component and the second spraying component are connected by a sliding bracket, which moves under the drive of an adjustment drive component, thereby synchronously adjusting the first and second distances. By integrating the first dispensing component and the first spraying component onto the frame, during use, dispensing and spraying of the power supply circuit board can be performed separately by moving the frame. Furthermore, by setting the second dispensing component and the second spraying component, they can work synchronously with the first dispensing component and the first spraying component, enabling operation on multiple power supply circuit boards, further improving efficiency. The positions of the second dispensing component and the second spraying component can be adjusted synchronously, thus adapting to different power supply production lines and enhancing practicality.

[0048] like Figure 1 , Figure 2 As shown, this embodiment proposes a dispensing and spraying mechanism, mainly including: a frame 100, a first dispensing component 200 and a first spraying component 300, a second dispensing component 210 and a second spraying component 310, a sliding bracket 400, and a positioning drive assembly 500. The frame 100 can adopt a roughly square structure. For example, the frame 100 specifically includes a support plate 110 and a panel pad 120. The support plate 110 can be a square plate with a protruding connecting block 111 at the upper end. The protruding connecting block 111 is used to connect the panel pad 120 and fix it to the moving mechanism through the panel pad 120. In this way, the entire dispensing and spraying mechanism can be driven to move by the moving mechanism. The moving mechanism can be a robotic arm or an XYZ linear motion mechanism. To avoid the panel pad 120 interfering with the lifting cylinder of the entire dispensing and spraying mechanism, the size of the panel pad 120 is optimized by changing the length from 77mm to 95mm.

[0049] like Figure 1 , Figure 2As shown, the square support plate 110 is placed vertically along the vertical direction. It has a length direction and a width direction on the horizontal plane. The length direction is the direction of the longer side, and the width direction is the direction of the thickness. For ease of structural description, the length direction is also the front-to-back direction, and the width direction is also the left-to-right direction. The support plate 110 has a first face and a second face facing each other along its width direction. The first adhesive dosing component 200 and the first spraying component 300 are fixed to opposite sides of the frame 100 along its width direction. The first adhesive dosing component 200 is located on the first face, and the first spraying component 300 is located on the second face. In other structures, the first adhesive dosing component 200 can be located on the second face, and the first spraying component 300 can be located on the first face, achieving the same function. For ease of structural description, this embodiment uses an example where the first adhesive dot 200 is located on the first surface and the first spray coating 300 is located on the second surface. The second adhesive dot 210 and the second spray coating 310 are slidably disposed on opposite sides of the frame 100, respectively. The second adhesive dot 210 and the second spray coating 310 are connected by a sliding bracket 400 and slide synchronously. The second adhesive dot 210 can be disposed on the same side as the first adhesive dot 200 or on the opposite side; the second spray coating 310 can be disposed on the same side as the first adhesive dot 200 or on the opposite side. For ease of structural description, this embodiment uses an example where the second adhesive dot 210 is slidably disposed on the first surface of the frame 100 and the second spray coating 310 is slidably disposed on the second surface of the frame 100. The adjustment drive assembly 500 is disposed on the frame 100 and connected to the sliding bracket 400. The sliding bracket 400 is driven by the adjustment drive assembly 500 to synchronously adjust the first distance and the second distance, wherein the first distance is the distance between the first adhesive dot 200 and the second adhesive dot 210, and the second distance is the distance between the first spraying part 300 and the second spraying part 310.

[0050] In this embodiment, the dispensing and spraying mechanism fixes the first dispensing component 200 and the first spraying component 300 to the frame 100, and additionally sets the second dispensing component 210 and the second spraying component 310, which are movable in position, on the frame 100. The distance between the first dispensing component 200 and the second dispensing component 210 is the first distance, and the distance between the first spraying component 300 and the second spraying component 310 is the second distance. Thus, the second dispensing component 210 and the second spraying component 310 are connected by a sliding bracket 400. The sliding bracket 400 moves under the drive of the adjustment drive component 500, thereby synchronously adjusting the first distance and the second distance. By integrating the first dispensing component 200 and the first spraying component 300 onto the frame 100, the power supply circuit boards can be dispensed and sprayed separately by moving the frame 100 during use. Furthermore, by providing a second dispensing component 210 and a second spraying component 310, they can work synchronously with the first dispensing component 200 and the first spraying component 300, enabling the processing of multiple power supply circuit boards and further improving efficiency. The positions of the second dispensing component 210 and the second spraying component 310 can be adjusted synchronously, thus adapting to different power supply production lines and enhancing practicality.

[0051] like Figure 1 , Figure 2 , Figure 4 As shown, in some embodiments, the adjustment drive assembly 500 includes a linear drive unit 510 and a power unit 520. The linear drive unit 510 is disposed along the length direction on the frame 100, and the sliding bracket 400 is disposed at the output end of the linear drive unit 510. The power unit 520 is connected to the linear drive unit 510 to provide power for the movement of the output end of the linear drive unit 510. The power unit 520 can be electrically driven or manually driven. Power is provided by the power unit 520 to move the output end of the linear drive unit 510 along the length direction, thereby driving the sliding bracket 400 to move in the front-back direction. The linear drive unit 510 can be a ball screw assembly 511 or a screw 511, a lead screw assembly, etc.

[0052] like Figure 2 , Figure 4As shown, in some embodiments, the linear drive unit 510 specifically includes a lead screw 511 and a nut connecting block 512. The two ends of the lead screw 511 are rotatably connected to one side of the frame 100 via bearing seats. The nut connecting block 512 is screwed onto the lead screw 511, serving as the output end. The sliding bracket 400 is fixed to the nut connecting block 512. Driven by the power unit 520, the lead screw 511 rotates, causing the nut connecting block 512 to move along the lead screw 511 in the front-to-back direction. This allows the sliding bracket 400 to synchronously move the second adhesive application component and the second spraying component, thereby adjusting the first distance and the second distance. The linear drive unit 510 can be disposed on the first surface or the second surface; for example, the linear drive unit 510 can be disposed on the second surface and located at the midpoint of the vertical direction of the first surface.

[0053] like Figure 2 , Figure 3 , Figure 4 As shown, in some embodiments, a first guide assembly 610 is provided on the frame 100. The first guide assembly 610 and the linear drive unit 510 are located on the same side of the frame 100 and connected to the sliding bracket 400 to guide the sliding bracket 400 along its length. In a specific structure, the first guide assembly 610 is located on the second side and includes a first upper guide rail 611 and an upper slide, as well as a first lower guide rail 612 and a lower slide. The sliding bracket 400 is connected to the upper slide and the lower slide, with the nut connecting block 512 positioned in the middle of the upper slide and the lower slide. This ensures that the force on the entire sliding bracket 400 is relatively uniform, achieving stable guidance of the sliding bracket 400.

[0054] like Figure 2 , Figure 3 , Figure 5 As shown, a second guide component 620 is also provided on the frame 100. The second guide component 620 and the first guide component 610 are respectively provided on the other side of the frame 100 and connected to the sliding bracket 400. The second guide component 620 is provided on the first surface. The second guide component 620 and the first guide component 610 have the same structure, and are provided with a second upper guide rail 621 and an upper slide, as well as a second lower guide rail 622 and a lower slide. The part of the sliding bracket 400 connected to the first surface is connected to the upper slide and the lower slide, so that the sliding bracket 400 can achieve stable guided sliding on both the first surface and the second surface.

[0055] like Figure 2 , Figure 3As shown, in some embodiments, the power unit 520 includes an adjustment knob 521, which drives the output end of the linear drive unit 510 to slide along the length direction by turning the adjustment knob 521. The manual adjustment method simplifies the structure, allowing for manual adjustment according to product parameters before production, resulting in low cost and greater practicality. The sliding bracket 400 fixes the second spraying parts 310 and the second adhesive dots 210 on both sides, enabling the adjustment knob 521 to be turned once to simultaneously adjust the second spraying parts 310 and the second adhesive dots 210 on both sides, maintaining precise and synchronized adjustment.

[0056] like Figure 2 , Figure 4 As shown, the frame 100 is further provided with a measuring scale 130, which extends a predetermined length along the length direction and is used to indicate the length value of a first distance or a second distance. The length moved by the sliding bracket 400 can be manually observed through the measuring scale 130, allowing for intuitive reading of the length and convenient manual adjustment.

[0057] like Figure 2 , Figure 3 As shown, in some embodiments, the sliding bracket 400 includes: a sliding spraying pad 410, a sliding adhesive dispensing pad 420, and a sliding connecting plate 430. The sliding spraying pad 410 is slidably disposed on one side of the bracket 100 and connected to the second spraying component 310. The sliding adhesive dispensing pad 420 is slidably disposed on the other side of the bracket 100 and connected to the second adhesive dispensing component 210. The sliding connecting plate 430 extends along the width direction and its two ends are respectively connected to the sliding spraying pad 410 and the sliding adhesive dispensing pad 420. One of the sliding spraying pad 410 and the sliding adhesive dispensing pad 420 is connected to the adjustment drive assembly 500. In a specific structure, the sliding spraying pad 410 is connected to the first guide assembly 610 on the first surface and extends in the vertical direction, with its lower end protruding from the lower surface of the support plate 110. The sliding adhesive dispensing pad 420 is located on the second guide assembly 620 on the second surface and extends in the vertical direction, with its lower end protruding from the lower surface of the support plate 110. The sliding connecting plate 430 is located below the support plate 110 and is spaced a certain distance from the support plate 110, so that the sliding bracket 400 can slide stably on the frame 100.

[0058] like Figure 1 , Figure 6 As shown, in some embodiments, a locking component 700 is provided on the sliding bracket 400, which is used to generate friction between the sliding bracket 400 and the frame 100 to lock the sliding bracket 400.

[0059] For example, the locking component 700 can be a screw, which passes directly through the sliding bracket 400 and presses against the frame 100 to lock the sliding bracket 400.

[0060] like Figure 6 , Figure 7 As shown, for example, the locking assembly 700 can be a quick-release locking structure, which is set on the sliding connecting plate 430. In a specific structure, a hinge seat 431 is provided on the sliding connecting plate 430. The locking assembly 700 includes a pressure rod 720, which has an oblong hole 721 along its length. The pressure rod 720 is movably connected to the hinge seat 431 through the oblong hole 721, so that the pressure rod 720 can move along its length and rotate around the hinge seat 431. The pressure rod 720 has an opposing pressing end 722 and a quick-connect end 724. The pressing end 722 protrudes toward the lower surface of the support plate 110, and the quick-connect end 724 is provided with a quick-connect piece 730, which can be locked onto the sliding connecting plate 430. A locking tooth 112 is provided on the lower surface of the support plate 110, and a hook tooth 723 is provided on the pressing end 722. After the adjustment drive assembly 500 adjusts the position of the sliding bracket 400, the pressing end 722 of the pressure rod 720 is raised, so that the hook tooth 723 is pressed into the locking tooth 112 on the lower surface of the support plate 110 to achieve locking engagement. Furthermore, the quick connector 730 applies force to the quick connector end 724 of the pressure rod 720, so that the pressing end 722 of the pressure rod 720 has a large pressing force and is pressed into the locking tooth 112 on the lower surface of the support plate 110. Then, the quick connector 730 is locked onto the sliding connecting plate 430 to achieve stable locking of the sliding bracket 400.

[0061] like Figure 7 As shown, since the pressure rod 720 can move back and forth (in the length direction) on the hinge seat 431, the position of the pressure rod 720 can be adjusted back and forth when the sliding bracket 400 is fixed. This allows the position of the hook tooth 723 of the pressing end 722 to be adjusted in the back and forth direction. Without changing the fixed position of the sliding bracket 400, the hook tooth 723 can be aligned with the locking tooth 112 on the lower surface of the support plate 110. This ensures that the fixed position of the sliding bracket 400 is not affected while achieving a stable locking function.

[0062] like Figure 7As shown, the quick-connect component 730 may further include a hinge joint 731, which is hinged to the quick-connect end 724 of the pressure rod 720. A threaded rod 732 is screwed onto the hinge joint 731, and an eccentric handle 733 is hinged to the other end of the threaded rod 732. A U-shaped slot 432 is provided on the sliding connecting plate 430, and the threaded rod 732 can rotate into the U-shaped slot 432. By pressing the eccentric handle 733, the quick-connect end 724 is moved away from the lower surface of the support plate 110 under eccentric action, and the threaded rod 732 is fixed in the U-shaped slot 432.

[0063] The screw rod 732 can be rotated to rise and fall on the hinge joint 731, thereby adjusting the clamping force of the eccentric handle 733 and also adjusting the clamping force of the pressing end 722 of the pressure rod 720, thus adjusting the degree of locking.

[0064] like Figure 1 , Figure 2 As shown, in some embodiments, the first dispensing component 200 is connected to the frame 100 via a fixing dispensing pad 140, so that the dispensing nozzle of the first dispensing component 200 coincides with the dispensing nozzle of the second dispensing component 210 in the width direction. The first spraying component 300 is connected to the frame 100 via a fixing spraying pad 150, so that the dispensing nozzle of the first spraying component 300 coincides with the dispensing nozzle of the second spraying component 310 in the width direction.

[0065] like Figure 1 , Figure 2 As shown, in the specific structure, both the first dispensing component 200 and the second dispensing component 210 include a cylinder 212 and a dispensing gun 211. Both the first spraying component 300 and the second spraying component 310 include a cylinder and a spray gun 311. By setting a fixed dispensing pad 140 and a fixed spraying pad 150, the fixed dispensing gun 211 and the slidable dispensing gun 211 are made substantially flush with each other in the left-right direction, and the fixed spray gun 311 and the slidable spray gun 311 are also made substantially flush. This eliminates the need for additional fine-tuning in the left-right direction when working with multiple power circuit boards, thus improving efficiency.

[0066] In addition, cylinders 212 are all controlled by solenoid valves controlled by PLC for extension and retraction. Therefore, a synchronous start trigger signal is added to the PLC controller. After receiving the synchronous start trigger signal, the PLC controller simultaneously sends a cylinder synchronous control command to the control output pin. After receiving the cylinder synchronous control command, the solenoid valves connected to the four cylinders simultaneously drive the four cylinders to ensure that the lifting and lowering commands of all cylinders are output at the same time. Then, the on and off time of the solenoid valves is controlled by pulse output to precisely adjust the lifting and lowering speed.

[0067] like Figure 8As shown, in some embodiments, a first synchronous detection component 160 is provided between the first dispensing component 200 and the second dispensing component 210, and a second synchronous detection component 170 is provided between the first spraying component 300 and the second spraying component 310. The deviation between the first distance and the second distance is detected by comparing the measured values ​​between the first synchronous detection component 160 and the second synchronous detection component 170. Specifically, since both the dispensing gun 211 and the spraying gun 311 are driven by cylinders fixed to the sliding bracket 400, slight misalignment of the dispensing gun 211 and the spraying gun 311 may occur during use due to the impact force of the cylinders. The dispensing and spraying mechanism of this application needs to operate on miniature precision components on the power supply circuit board, requiring high precision. Therefore, by setting the first synchronous detection component 160 and the second synchronous detection component 170, real-time and accurate monitoring of the first distance and the second distance is achieved, avoiding excessive errors.

[0068] like Figure 8 As shown, in the specific structure, taking the first synchronous detection component 160 as an example, it includes a first elastic connector 161 (e.g., a spring), a tension gauge 162, and a second elastic connector 163. The first elastic connector 161 is fixed to the first dispensing component 200 (e.g., a cylinder), and the second elastic connector 163 is fixed to the second dispensing component 210 (e.g., a cylinder). The second synchronous detection component 170 has the same structure and is connected to the first spraying component 300 and the second spraying component 310. Before use, after adjusting the position, the tension gauges 162 on both sides are zeroed. After multiple dispensing and spraying operations, the readings of the two gauges are observed to see if they are 0. This allows for the determination of whether there is a deviation between the first distance and the second distance. When the deviation exceeds the predetermined quality range, the distance between the two cylinders can be adjusted in time to meet the quality requirements. Therefore, based on the change in tension caused by the change in the distance on both sides, the first distance and the second distance can be accurately monitored. In addition, through the elastic action of the first and second synchronous detection components, a preload force can be applied to the entire sliding bracket toward the first adhesive part (or the first sprayed part). This preload force can cause the threaded contact surface of the screw to move toward one side of the length direction during the rotation of the screw (the side facing the first adhesive part or the first sprayed part). In this way, the error caused by the assembly gap can be reduced during the screw's tightening process, thereby improving the positional accuracy of the entire sliding bracket after being moved during the screw's rotation.

[0069] This application also proposes a dispensing and spraying operation method, wherein the dispensing and spraying operation method is applied to the above-mentioned dispensing and spraying mechanism and includes the following steps:

[0070] Step 10: Place the product into the fixture, so that the fixture is located at the inlet docking station. The conveying mechanism is activated by sensing and transporting the fixture to the predetermined work position.

[0071] In the specific process, the loading and conveying are carried out first, with an estimated time of 0-5 seconds. The PCB board of the power supply is manually placed into the fixture, which is pre-positioned at the inlet receiving platform. Once the conveyor mechanism senses that the PCB board is in place, it starts and conveys it at a constant speed to the positioning baffle, achieving positioning at the predetermined work position. This process utilizes the coordination of the conveyor mechanism (motor + conveyor belt) and the loading device to input the product.

[0072] Next, positioning and calibration are performed. The fixture with the PCB board is detected by the sensor in 5-10 seconds, and then the fixture is clamped and fixed by the mechanical clamp.

[0073] Simultaneously, paint supply preparation is carried out. Within 10-15 seconds, the paint in the storage tank is squeezed according to the preset air pressure (0.2-0.5MPa), filtered through the filter screen, and then sent to the coating head.

[0074] Step 100: Receive the sensor's sensing signal and determine that the fixture carrying the product has reached the predetermined work position, wherein the reception of the sensor's sensing signal reaches a predetermined time.

[0075] In the specific process, the input signal of the position sensor (photoelectric switch) is detected and continuously monitored. A "delay filtering" function is added to the PLC to delay the sensing signal by 10ms. That is, the input signal of the position sensor (photoelectric switch) is sensed for 10ms before it is considered a valid signal and the predetermined work position is determined. This can filter out false signals caused by electromagnetic interference or sensor jitter.

[0076] Step 200: Control the first and second dispensing components to move synchronously to the predetermined dispensing position.

[0077] Step 300: Control the first and second dispensing components to perform dispensing operations based on a preset path. If the dispensing time exceeds a preset threshold during the dispensing process, control the first and second dispensing components to shut down and trigger an alarm.

[0078] In the specific process, upper and lower thresholds are set for key parameters of glue dispensing (such as dispensing time). The PLC monitors external sensors and relays in real time for control. If the working time of the glue gun exceeds the upper or lower threshold during dispensing, the surface dispensing fails, the glue gun is forcibly shut down, and an alarm signal is issued. This avoids the problem of glue gun control malfunctioning.

[0079] Step 400: Detect that the first and second dispensing components have completed dispensing, control the first and second dispensing components to rise back to their initial dispensing positions, and simultaneously control the first and second spraying components to descend to their predetermined spraying positions.

[0080] Step 500: Control the first and second spraying parts to perform spraying operations based on the preset path. If the spraying time exceeds a preset threshold during the spraying process, control the first and second spraying parts to shut down and trigger an alarm.

[0081] In the specific process, upper and lower thresholds are set for key atomization parameters (such as atomization time). The PLC monitors external sensors and relays in real time for control. If the working time of the atomizing gun exceeds the upper or lower threshold during the spot spraying atomization process, the surface atomization spraying is unsuccessful, the atomizing gun is forcibly shut down, and an alarm signal is issued. This avoids the problem of the atomizing gun control not working properly.

[0082] Step 600: After detecting that the first and second sprayed parts have completed spraying, control the first and second sprayed parts to rise back to the initial spraying position.

[0083] During the above process, precise coating is applied. Within 15-65 seconds, the first dispensing component (second dispensing component) and the first spraying component (second spraying component) move along a preset path (X / Y / Z axis linkage) driven by the moving mechanism to cover the designated area in the form of spraying / dispensing / brushing, and complete the main dispensing and spraying processes.

[0084] Step 700: Control the dispensing and spraying mechanism to move to the machine origin, and at the same time control the equipment conveyor track to let the finished product flow out of the predetermined operation position.

[0085] In the specific process, the material is fed in within 0-5 seconds. After the coating is completed, the conveyor sends it to the docking station to check the coating thickness and missing coating. If it passes the inspection, it is cured.

[0086] It should be understood that the application of this application is not limited to the examples above. Those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
