Description

Technical Field

[0001] This application relates to the field of AC gun manufacturing, and in particular to AC gun potting production lines and manufacturing processes. Background Technology

[0002] An AC charging gun is a device used for charging electric new energy vehicles, serving to connect the power source and the vehicle. The AC charging gun consists of a non-conductive plastic shell and internal conductive metal components. The tail of the AC charging gun connects to the power source via a cable. The user holds the outer shell of the AC charging gun and inserts the nozzle into the corresponding charging port on the vehicle to charge it.

[0003] To facilitate the assembly of AC guns, existing AC guns consist of a left shell and a right shell, with internal metal parts installed between them. The left and right shells are then connected to form the outer casing. To enhance the structural strength of the AC gun, a mounting port for injecting adhesive is provided between the left and right shells. This allows adhesive to be injected into the AC gun casing, and the rear decorative panel is then installed into the mounting port to seal the AC gun. However, excessive shrinkage may occur when the adhesive solidifies, pulling on the left and right shells and causing the size and shape of the mounting port to not conform to the design dimensions, making it impossible to install the rear decorative panel. Manual correction may damage the AC gun, thus requiring improvement. Summary of the Invention

[0004] In order to improve the yield rate of AC gun assembly and potting, this application provides an AC gun potting production line and production process.

[0005] Firstly, the AC gun potting production line provided in this application adopts the following technical solution:

[0006] An AC gun potting production line includes a riveting mechanism, a testing mechanism, a dispensing mechanism, a drying mechanism, and a conveyor belt. A straightening mechanism is also provided on the side of the drying mechanism away from the dispensing mechanism to straighten the dried AC gun. The straightening mechanism includes a spreading component, a spreading drive component, and a workbench. A worktable is movably mounted on the workbench and reciprocates vertically. The spreading component is mounted on the worktable, and the worktable drives the spreading component to descend and insert into the mounting port of the AC gun. The spreading drive component is mounted on the workbench or worktable and drives the spreading component to straighten the mounting port of the AC gun.

[0007] Using the above technical solution, the operator places the aligned left and right shells into the riveting mechanism, which then rivets the shells together. The operator transfers the AC gun to the testing platform of the testing mechanism for component testing. The tested AC gun is then installed on a conveyor belt, which transports it into the glue-filling mechanism. This mechanism injects the mixed adhesive into the shell through the mounting port. After filling, the conveyor belt transports the AC gun from the glue-filling mechanism to the drying tunnel of the drying mechanism to accelerate adhesive curing. Once the adhesive in the AC gun is dry, the conveyor belt removes the AC gun from the drying mechanism. The operator removes the AC gun and installs the rear decorative panel onto the shell through the mounting port. If installation is impossible due to a small mounting port, the operator installs the AC gun onto the straightening mechanism, straightens the mounting port, and then installs the rear decorative panel. The assembly and potting of the AC gun were realized, which improved the strength of the AC gun body; the problem of the rear decorative panel being unable to be installed due to excessive shrinkage of the adhesive was solved, and the yield rate of AC gun production was improved.

[0008] Optionally, two of the spreading components are symmetrically arranged in the width direction of the worktable. Each spreading component includes a mounting block, a spreading plate, and a guide rod. The mounting block is slidably mounted on the worktable and has a guide hole. One end of the guide rod is connected to the worktable, and the other end is inserted into the guide hole. The two mounting blocks move closer to or further away from each other along the length of the guide rod. A return spring is sleeved on the guide rod. One end of the return spring is connected to the worktable, and the other end is connected to the mounting block. The spreading plate is mounted on the bottom of the mounting block. The spreading drive component drives the two mounting blocks to move away from each other, thereby causing the two spreading plates to move away from each other in the horizontal direction.

[0009] Optionally, the spreading drive assembly includes a first pressing guide cone and a pressing drive component. The pressing drive component is mounted on a worktable above the two spreading components, and the first pressing guide cone is mounted on the pressing drive component. A first anti-friction roller is provided directly below the first pressing guide cone. The first anti-friction roller is rotatably connected to the side wall of the mounting block away from the worktable via a rotating shaft. The first pressing guide cone descends and contacts the two first anti-friction rollers simultaneously, thereby causing the two first anti-friction rollers to move away from each other, so that the two mounting blocks move away from each other.

[0010] By adopting the above technical solution, the lifting cylinder drives the worktable to descend until the two expansion plates are inserted into the mounting opening and then stop; the downward driving component is activated, and the piston rod of the downward driving component drives the first downward guiding cone to descend vertically until the tip of the first downward guiding cone is inserted between the two anti-friction rollers, and the inclined sidewall of the first downward guiding cone simultaneously contacts the peripheral wall of the two anti-friction rollers; the first downward guiding cone continues to descend, forcing the two anti-friction rollers to separate from each other, causing the two mounting blocks to move away from each other along the length of their respective guide rods, at which point the return spring is compressed; the two expansion plates respectively abut against the two sidewalls in the width direction of the mounting opening, and after the mounting opening is opened to the designed size, the first downward guiding cone stops descending. After the AC gun straightening process is completed, the piston rod of the downward driving component drives the first downward guiding cone to rise, the return spring causes the two mounting blocks to move closer to each other, and the two expansion plates to move closer to each other; the piston rod of the lifting cylinder drives the worktable to rise, causing the expansion plates to retract from the mounting opening. The expansion drive component enables semi-automatic correction of the mounting port, reducing damage to the AC gun caused by manual correction and improving the yield rate of AC gun production.

[0011] Optionally, the spreading drive assembly includes a drive cylinder, a second downward guide cone, and a linkage. The drive cylinder is mounted on the top wall of the work frame. The linkage includes a first rack, a second rack, a first gear, and a second gear. The piston rod of the drive cylinder passes through the top wall of the work frame and is connected to one end of the first rack. The second rack is disposed on one side of the first rack and is slidably connected to the work frame. A limit hole is formed on the top wall of the work frame, through which the second rack passes. A limit block is installed at the end of the second rack passing through the limit hole to limit the range of movement of the second rack. The end of the second rack away from the limit block is connected to the worktable. The first gear and the second gear are disposed between the first rack and the second rack. Both the first gear and the second gear are rotatably connected to the work frame. The first gear meshes with the first rack, and the second gear meshes with the second rack. The second gear has a partially smooth surface on its peripheral wall. The end of the first rack away from the drive cylinder is connected to the second downward guide cone. The mounting block is rotatably mounted on the side wall away from the worktable. The first rack drives the second downward guide cone to descend and contact the two second anti-friction rollers simultaneously, thereby causing the two second anti-friction rollers to move away from each other, so that the two mounting blocks move away from each other.

[0012] By adopting the above technical solution, the drive cylinder drives the first rack to move downwards, the first gear rotates counterclockwise, the second gear rotates clockwise, and the second rack moves downwards. At this time, the smooth surface of the second gear moves from the top of the second gear towards one side of the second rack. When the smooth surface of the second gear reaches the second rack, the second rack stops moving, the limit block is in contact with the top wall of the work frame, and the worktable descends to the designated position. The drive cylinder drives the first rack to continue descending, and the first rack drives the second downward pressure guide cone to be inserted between the two second anti-friction rollers to separate the two spreading plates. During this process, the smooth surface of the second gear remains at the second rack. When the correction is completed, the drive cylinder drives the first rack and the second downward pressure guide cone to move upwards, at which time the two spreading plates are reset under the action of the return spring. The first rack moves upward, at which point the first gear rotates clockwise and the second gear rotates counterclockwise. The smooth surface of the second gear moves from the second rack towards the first gear, while the second rack remains stationary throughout this movement. When the smooth surface of the second gear is above the second rack, the second gear meshes with the second rack again. The continuous rotation of the first gear drives the second gear to rotate, causing the second rack to move upward, thus raising the worktable. When the piston rod of the drive cylinder fully retracts into the cylinder body, the worktable, the second downward guide cone, and the two expansion plates all return to their original positions. The linkage design reduces the number of cylinders, reduces the adjustment time required for cylinder coordination, simplifies the straightening action, and improves the efficiency of the straightening process.

[0013] Optionally, the correction mechanism is further provided with an alignment component, which includes a positioning ball, a connecting rope, and a rope winding shaft; the rope winding shaft is mounted on the second gear, the connecting rope is wound around the rope winding shaft, a through hole is provided on the worktable, the end of the connecting rope away from the rope winding shaft passes through the through hole and is connected to the positioning ball; the positioning ball can contact the front end of the AC gun housing.

[0014] Optionally, a positioning ring is fitted onto the connecting rope, and the positioning ring is mounted on the worktable to limit the position of the positioning ball.

[0015] By adopting the above technical solution, when the piston rod of the drive cylinder is fully retracted into the cylinder body, the positioning ball is at its lowest position. The operator pushes the AC gun towards the positioning ball. When the positioning ball contacts the front end of the AC gun, it means the AC gun has moved to the correction position. The drive cylinder can then be activated, thereby causing the two expansion plates to open the inner walls on both sides of the AC gun mounting port through the linkage. During the extension of the piston rod of the drive cylinder, the second gear rotates clockwise, thereby winding the connecting rope onto the winding shaft. At this time, the positioning ball rises. When the piston rod of the drive cylinder is fully extended, the AC gun is in the correction state, and the positioning ball is in contact with the bottom wall of the positioning ring. When the correction of the AC gun is completed, the piston rod of the drive cylinder retracts, the second gear rotates counterclockwise, thereby unwinding the connecting rope from the winding shaft. The positioning ball returns to its lowest point under the action of gravity to position the next AC gun. The alignment component is designed to facilitate operator alignment, allowing the expansion plates to be smoothly inserted into the mounting port during descent, improving the accuracy of correction and operational efficiency.

[0016] Optionally, the correction mechanism is provided with a clamping assembly, which includes a mounting plate, a lifting rod, two clamping rods, and two clamping blocks. The mounting plate is mounted on a work frame, and the two clamping rods are rotatably connected to the mounting plate. Each of the two clamping rods has a sliding hole, and the two clamping rods are arranged crosswise. A sliding rod is inserted into the two overlapping sliding holes. The end of the sliding rod away from the clamping rod is connected to the lifting rod, and the end of the lifting rod away from the sliding rod is connected to the worktable. The clamping block is mounted on the end of the clamping rod away from the mounting plate, and the side wall of the clamping block can be abutted against the outer side wall of the AC gun mounting port. When the sliding rod rises vertically, it causes the two clamping blocks to move closer to each other to clamp the AC gun.

[0017] By adopting the above technical solution, the drive cylinder starts, and the worktable and the second downward guide cone descend synchronously. At this time, the lifting rod drives the sliding rod to descend vertically. The sliding rod moves within the sliding hole, causing the movable end of the clamping rod to rotate downwards with its pivot connected to the mounting plate as the center, and the two clamping blocks move closer to each other. Until the worktable stops descending, the two expansion plates are inserted into the mounting opening. At this time, the two clamping blocks are located on both sides of the AC gun, and the distance between the two clamping blocks is the standard distance after the left and right shells of the AC gun are expanded. At this time, the second downward guide cone continues to descend, and the two expansion plates expand the two side walls of the mounting opening to both sides. When the outer sides of the left and right shells of the AC gun are in contact with the clamping blocks, the second downward guide cone moves down to the lowest distance, and the two expansion plates expand the mounting opening of the AC gun to the required size. When the AC gun calibration is complete, the piston rod of the drive cylinder retracts, and the two expansion plates first move closer together, releasing the expansion effect on the side walls of the AC gun. Then, the worktable rises, the expansion plates move out of the AC gun's mounting port, the sliding rod moves upward, and drives the movable end of the clamping rod to rotate upward with its connection point with the mounting plate as the center. The two clamping blocks move away from each other, releasing the clamping of the left and right shells of the AC gun. The clamping assembly reduces the possibility of damage to the AC gun's outer shell during the expansion process, improving the yield rate of the calibration process.

[0018] Optionally, an adjustment assembly is provided below the workbench to move the AC gun below the spreading assembly; the adjustment assembly includes an adjustment plate and an adjustment frame, the adjustment frame is slidably mounted on the workbench and moves closer to and further away from the workbench in the horizontal direction; the adjustment plate is rotatably connected to the adjustment frame; the AC gun is mounted on the adjustment plate via a fixture, and the adjustment plate is used to adjust the angle of the AC gun.

[0019] By adopting the above technical solution, the operator inserts the AC gun into the fixture on the adjustment plate, at which point the adjustment frame is away from the workbench. The operator then pushes the adjustment frame closer to the workbench and adjusts the angle of the adjustment plate so that the mounting opening faces upwards and is directly below the spreading assembly. Once the operator has moved out of the danger zone, calibration can begin. After calibration, the operator pulls the adjustment frame back away from the workbench to remove the AC gun. The adjustment assembly facilitates the operator's adjustment and fixation of the AC gun angle, reducing the possibility of accidental injury to the operator during calibration and improving the safety of equipment use.

[0020] Secondly, this application also discloses the production process of the AC gun filling production line:

[0021] The process for filling and sealing AC guns includes the following steps:

[0022] Riveting: The left and right shells of the AC gun are initially assembled by the riveting mechanism, with an installation opening left between the left and right shells;

[0023] Testing: The conductivity of the electronic components inside the AC gun housing is tested using the aforementioned testing mechanism;

[0024] Glue filling: The glue filling mechanism fills the AC gun with glue from the mounting port;

[0025] Drying: When the AC gun is drying in the drying mechanism, the mounting port of the AC gun always faces upward;

[0026] Correction: The expansion plate is inserted into the mounting port of the AC gun. The expansion drive assembly drives the two expansion plates to separate from each other, correcting the mounting port to the set size.

[0027] Assembly: Install the rear trim panel onto the AC gun housing through the mounting port.

[0028] Optionally, the dispensing head of the dispensing mechanism is inserted into the housing of the AC gun from the mounting port until it approaches the nozzle of the AC gun, and dispensing is performed while the dispensing head is pulled outward.

[0029] By adopting the above technical solutions, the AC gun components are produced through riveting, inspection, glue filling, drying, straightening and assembly processes, which improves the strength of the AC gun body and increases the yield rate of AC gun production.

[0030] In summary, this application includes at least one of the following beneficial technical effects:

[0031] 1. The operator places the aligned left and right shells into the riveting mechanism, which then rivets the shells together. The operator transfers the AC gun to the testing platform of the testing mechanism for component testing. The tested AC gun is then installed on a conveyor belt, which transports it into the glue-filling mechanism. This mechanism injects the mixed glue into the shell through the mounting port. After filling, the conveyor belt transports the AC gun from the glue-filling mechanism to the drying tunnel of the drying mechanism to accelerate glue curing. Once the glue inside the AC gun is dry, the conveyor belt removes the AC gun from the drying mechanism. The operator removes the AC gun and installs the rear decorative panel onto the shell through the mounting port. If installation is impossible due to a small mounting port, the operator installs the AC gun onto the straightening mechanism, straightens the mounting port, and then installs the rear decorative panel. This process achieves the assembly and potting of the AC gun, improving its strength; it also solves the problem of the rear decorative panel being unable to be installed due to excessive glue shrinkage, thus improving the yield rate of AC gun production.

[0032] 2. The expansion drive component enables semi-automatic correction of the mounting port, reducing damage to the AC gun caused by manual correction and improving the yield rate of AC gun production.

[0033] 3. The operator inserts the AC gun into the fixture on the adjusting plate, with the adjusting bracket away from the workbench. The operator then pushes the adjusting bracket closer to the workbench and adjusts the angle of the adjusting plate so that the mounting opening faces upwards and is directly below the spreading assembly. The operator then moves out of the danger zone of the equipment and can begin the correction process. After correction, the operator pulls the adjusting bracket back away from the workbench to remove the AC gun. The adjusting assembly facilitates the operator's adjustment and fixation of the AC gun angle, reducing the possibility of accidental injury to the operator during correction and improving the safety of equipment use.

[0043] The following is in conjunction with the appendix Figure 1-8 This application will be described in further detail.

[0044] Example 1

[0045] Embodiment 1 of this application discloses an AC gun filling production line. (Refer to...) Figure 1 The AC gun potting production line includes a riveting mechanism 1, which is used for the initial assembly of the left and right shells of the AC gun. A testing mechanism 2 is located on one side of the riveting mechanism 1 to test the AC gun. A glue-filling mechanism 3 is located on the side of the testing mechanism 2 away from the riveting mechanism 1, which fills the AC gun shell with glue from the mounting port to strengthen the AC gun. A drying mechanism 4 is located on the side of the glue-filling mechanism 3 away from the testing platform to dry the glue inside the AC gun. The AC gun potting production line also includes a conveyor belt 5, which runs through the glue-filling mechanism 3 and the drying mechanism 4 for transporting the AC gun. A straightening mechanism 6 is located on the side of the conveyor belt 5 away from the drying mechanism 4, which straightens the mounting port to facilitate the installation of the decorative panel.

[0046] The operator places the aligned left and right shells into the riveting mechanism 1. The riveting mechanism 1 is activated to rivet the left and right shells together, leaving an installation opening between them. The operator transfers the AC gun to the testing table of the testing mechanism 2 to test its components. The tested AC gun is then installed on the conveyor belt 5, with the installation opening facing upwards. The conveyor belt 5 transports the AC gun into the glue-filling mechanism 3, which is activated to pour the mixed glue into the shell through the installation opening. After filling, the conveyor belt 5 transports the AC gun from the glue-filling mechanism 3 to the drying tunnel of the drying mechanism 4 to accelerate the curing of the glue. Once the glue inside the AC gun is dry, the conveyor belt 5 removes the AC gun from the drying mechanism 4. The operator removes the AC gun and installs the rear decorative panel onto the shell through the installation opening. If the installation opening is too small to install, the operator installs the AC gun onto the straightening mechanism 6 and activates the straightening mechanism 6 to straighten the installation opening. The rear decorative panel is then installed, and the AC gun shell is successfully sealed.

[0047] Reference Figure 2 and 3 The straightening mechanism 6 includes a work frame 63, with an adjustment component 65 mounted at the bottom of the work frame 63. A worktable 64 is movably mounted above the adjustment component 65. The worktable 64 is driven by a lifting cylinder 641, which is mounted on the work frame 63, and the worktable 64 is connected to the piston rod of the lifting cylinder 641. Two spreading components 61 are symmetrically mounted on the worktable 64 along its width. A spreading drive component 62 is also mounted on the worktable 64 to drive the two spreading components 61 away from each other to straighten the mounting opening.

[0048] When correction is required, the operator installs the AC gun onto the adjustment assembly 65, adjusts the position and angle of the AC gun so that the mounting port faces upward and is located below the two spreading assemblies 61; the piston rod of the lifting cylinder 641 drives the worktable 64 to descend, which in turn drives the two spreading assemblies 61 to descend and be inserted into the mounting port at the same time; the spreading drive assembly 62 is activated, which drives the two spreading assemblies 61 to correct the mounting port to the design size.

[0049] The adjustment assembly 65 includes an adjustment frame 652, which is slidably mounted on the work frame 63. The adjustment frame 652 can move horizontally closer to or further away from the worktable 64. An adjustment plate 651 is provided on the adjustment frame 652, and the adjustment plate 651 is rotatably connected to the adjustment frame 652 and can be locked relative to the adjustment frame 652 after rotation. A fixture is mounted on the adjustment plate 651, and an AC gun is inserted into the fixture. Rotation of the adjustment plate 651 drives the AC gun to rotate, so that the mounting port faces upward.

[0050] The expansion assembly 61 includes a mounting block 611, which is slidably connected to the side wall of the worktable 64. A guide hole 6111 is provided on the mounting block 611, extending through its length. A guide rod 614 is provided between the mounting block 611 and the worktable 64. One end of the guide rod 614 is connected to the worktable 64, and the other end is inserted into the guide hole 6111. The length of the guide rod 614 is parallel to the width of the worktable 64. The two mounting blocks 611 move closer to or further away from each other along the length of their respective guide rods 614. A return spring 615 is fitted on the guide rod 614. One end of the return spring 615 is connected to the worktable 64, and the other end is connected to the opposing side walls of the two mounting blocks 611. The bottom of the mounting block 611 is equipped with a support plate 613, which is set vertically and two support plates 613 hang above the mounting port. When the AC gun is installed on the adjustment component 65 and the mounting port is facing upward, the two support plates 613 can be inserted into the mounting port at the same time.

[0051] The expansion drive assembly 62 includes a first downward guide cone 621, which is movably mounted on the worktable 64. The tip of the first downward guide cone 621 hangs above two mounting blocks 611. A downward drive component 622 is provided on the first downward guide cone 621. In this embodiment, the downward drive component 622 is a cylinder. The downward drive component 622 is mounted on the worktable 64, and its piston rod is connected to the first downward guide cone 621. The piston rod of the downward drive component 622 drives the first downward guide cone 621 to descend vertically and insert it between the two mounting blocks 611. In order to reduce the friction between the first downward guide cone 621 and the mounting block 611, a first friction-reducing roller 612 is rotatably provided on the mounting block 611. The first friction-reducing roller 612 is mounted on the side wall of the mounting block 611 away from the worktable 64. The side wall of the first downward guide cone 621 can contact the peripheral walls of the two first friction-reducing rollers 612 at the same time.

[0052] The operator inserts the AC gun into the fixture on the adjustment plate 651, at which point the adjustment bracket 652 is away from the workbench 64. The operator pushes the adjustment bracket 652 closer to the workbench 64 and adjusts the angle of the adjustment plate 651 so that the mounting opening faces upward and is located directly below the support plate 613. The lifting cylinder 641 is activated, causing the worktable 64 to descend until the two expansion plates 613 are inserted into the mounting opening. The pressing drive 622 is activated, and the piston rod of the pressing drive 622 drives the first pressing guide cone 621 to descend vertically until the tip of the first pressing guide cone 621 is inserted between the two first anti-friction rollers 612, and the inclined sidewall of the first pressing guide cone 621 simultaneously contacts the peripheral wall of the two first anti-friction rollers 612. The first pressing guide cone 621 continues to descend, forcing the two first anti-friction rollers 612 to separate from each other, causing the two mounting blocks 611 to move away from each other along the length direction of their respective guide rods 614. At this time, the return spring 615 is compressed. The two expansion plates 613 respectively abut against the two sidewalls in the width direction of the mounting opening, and after opening the mounting opening to the designed size, the first pressing guide cone 621 stops descending. After the AC gun straightening process is completed, the piston rod of the downward drive component 622 drives the first downward guide cone 621 to rise. The return spring 615 brings the two mounting blocks 611 closer together, and the two expansion plates 613 bring them closer together. The piston rod of the lifting cylinder 641 drives the worktable 64 to rise, causing the expansion plates 613 to retract from the mounting opening. The operator pulls the adjusting frame 652 back away from the worktable 64, removes the AC gun, and installs the rear decorative panel into the mounting opening. The straightening mechanism 6 resets and awaits the next straightening command.

[0053] The implementation principle of the AC gun potting production line in Embodiment 1 of this application is as follows: the AC gun components are initially assembled by the riveting mechanism 1, inspected by the testing mechanism 2, potted by the glue-filling mechanism 3, and dried by the drying mechanism 4. Then, the operator assembles the rear decorative panel. If the installation port is too small and cannot be installed, the operator installs the AC gun on the adjusting component 65 and moves it below the two spreading components 61. The lifting cylinder 641 drives the two spreading plates 613 to be inserted into the installation port. The spreading drive component 62 drives the two spreading plates 613 to spread the installation port to the designed size. After the installation port is corrected, the operator can install the rear decorative panel at the installation port, and the AC gun shell potting is completed.

[0054] Example 2

[0055] The difference between this embodiment and Embodiment 1 is that, referring to... Figure 4 and Figure 5The expansion drive assembly 62 includes a drive cylinder 623 and a linkage 625. The drive cylinder 623 is fixed to the top wall of the work frame 63 by bolts, and the piston rod of the drive cylinder 623 extends into the work frame 63 through the top wall. The linkage 625 includes a first rack 6251, one end of which is fixed to the piston rod of the drive cylinder 623 by bolts.

[0056] A first gear 6253 is rotatably connected to the work frame 63 via a shaft, and the first gear 6253 meshes with a first rack 6251. A second gear 6254 is also rotatably connected to the work frame 63 via a shaft. The second gear 6254 is installed on the side of the first gear 6253 away from the first rack 6251. In this embodiment, the radii of the first gear 6253 and the second gear 6254 are equal. When the first rack 6251 reciprocates in the vertical direction, it drives the first gear 6253 to rotate. When the first gear 6253 rotates under the action of the first rack 6251, the first gear 6253 meshes with the second gear 6254 to drive the second gear 6254 to rotate in the opposite direction.

[0057] The second gear 6254 meshes with a second rack 6252 on the side away from the first gear 6253. A through hole 642 is provided on the top wall of the work frame 63. The top side wall of the second rack 6252 is made into a smooth surface. The top end of the second rack 6252 passes upward through the through hole 642 and is integrally formed with a limiting block 6255. The diameter of the limiting block 6255 is larger than the diameter of the through hole 642. The end of the second rack 6252 away from the limiting block 6255 is fixed to the worktable 64 by bolts.

[0058] The second gear 6254 has a smooth surface on its peripheral wall, which in this embodiment occupies one-quarter of the peripheral wall of the second gear 6254. When the second gear 6254 rotates, it first meshes with the second rack 6252 to drive the second rack 6252 to move vertically. When the smooth surface of the second gear 6254 rotates to the position of the second rack 6252, the second gear 6254 and the second rack 6252 do not mesh, and at this time the limiting block 6255 is in contact with the top wall of the work frame 63. The second gear 6254 continues to rotate, and the second rack 6252 cannot move.

[0059] The first rack 6251 extends downward from the end away from the drive cylinder 623 and is connected to the second downward guide cone 624. The second anti-friction roller 616 is rotatably connected to the side wall of the mounting block 611 away from the worktable 64 via a rotating shaft. When the drive cylinder 623 is activated, the piston rod of the drive cylinder 623 extends downward, and the first rack 6251 moves downward under the action of the drive cylinder 623, thereby driving the second downward guide cone 624 to move downward relative to the worktable, so that the second downward guide cone 624 is inserted between the two second anti-friction rollers 616, and the two second anti-friction rollers 616 are moved away from each other.

[0060] When the drive cylinder 623 is activated, the piston rod of the drive cylinder 623 extends, and the first rack 6251 moves downward. At this time, the first gear 6253 rotates counterclockwise under the action of the first rack 6251, and the second gear 6254 rotates clockwise under the action of the first gear 6253. The second rack 6252 moves downward under the action of the second gear 6254. At this time, the smooth surface of the second gear 6254 is located at the top of the second gear 6254 and moves from one side of the first gear 6253 to one side of the second rack 6252. When the smooth surface of the second gear 6254 moves to the second rack 6252, the second rack 6252 stops moving, the limit block 6255 is in contact with the top wall of the work frame 63, and the worktable 64 descends to the designated position. The drive cylinder 623 drives the first rack 6251 to continue to descend. The first rack 6251 drives the second downward guide cone 624 to be inserted between the two second anti-friction rollers 616 to separate the two spreading plates 613 in a direction away from each other. After the spreading plates 613 move to the designated position, they are held for the required time. During this process, the smooth surface of the second gear 6254 is always at the second rack 6252.

[0061] When the two expansion plates 613 complete their correction action on the AC gun, the piston rod of the drive cylinder 623 retracts, causing the drive cylinder 623 to move the first rack 6251 and the second downward guide cone 624 upward. At this time, the two expansion plates 613 are reset under the action of the return spring 615. The first rack 6251 moves upward, and the first gear 6253 rotates clockwise under the action of the first rack 6251, while the second gear 6254 rotates counterclockwise under the action of the first gear 6253. The smooth surface of the second gear 6254 moves from the second rack 6252 toward the first gear 6253. During the movement of the smooth surface of the second gear 6254 toward the second rack 6252, the second rack 6252 remains stationary. When the smooth surface of the second gear 6254 completely moves away from the second rack 6252... When the first gear 6254 disengages, its smooth surface is located between the first gear 6253 and the second rack 6252, and above the second gear 6254. At this time, the second gear 6254 meshes with the second rack 6252 again. The first gear 6253 continues to rotate, driving the second gear 6254 to rotate, thereby causing the second rack 6252 to move upward, which in turn drives the worktable 64 to rise. When the piston rod of the drive cylinder 623 is fully retracted into the cylinder body, the worktable 64, the second downward guide cone 624, and the two expansion plates 613 are all reset.

[0062] Reference Figure 4 and Figure 5 To ensure the expansion plate 613 can be smoothly inserted into the mounting opening during descent, the alignment mechanism 6 is equipped with an alignment component 67. The alignment component 67 includes a rope winding shaft 673, which is bolted to the second gear 6254 and rotates synchronously with it. A connecting rope 672 is wound around the rope winding shaft 673. One end of the connecting rope 672 is glued to the peripheral wall of the rope winding shaft 673, while the other end is movable. When the first rack 6251 descends, the second gear 6254 rotates clockwise, and the connecting rope 672 is wound around the rope winding shaft 673. At this time, the length of the connecting rope 672 outside the rope winding shaft 673 decreases, and the movable end of the connecting rope 672 rises. The workbench 64 has a through hole 642. The bottom wall of the workbench 64 is fixed with a positioning ring 674 by bolts. The end of the connecting rope 672 away from the rope winding shaft 673 passes through the through hole 642 and the positioning ring 674, and is connected to a positioning ball 671. Under the action of gravity, the positioning ball 671 hangs freely.

[0063] When the piston rod of the drive cylinder 623 is fully retracted into the cylinder body, the positioning ball 671 is at its lowest position. After the AC gun is inserted into the fixture, the operator pushes the fixture towards the positioning ball 671. When the positioning ball 671 contacts the front end of the AC gun, it means that the AC gun has moved to the correction position; the drive cylinder 623 can then be activated, thereby causing the two expansion plates 613 to open the inner walls on both sides of the AC gun mounting port through the linkage 625; during the extension of the piston rod of the drive cylinder 623, the second gear 6254... Rotating clockwise, the connecting rope 672 is wound around the rope winding shaft 673. At this time, the positioning ball 671 rises, and when the piston rod of the drive cylinder 623 is fully extended, the AC gun is in the correction state, and the positioning ball 671 is in contact with the bottom wall of the positioning ring 674. When the correction of the AC gun is completed, the piston rod of the drive cylinder 623 retracts, and the second gear 6254 rotates counterclockwise, thereby unwinding the connecting rope 672 from the rope winding shaft 673. Under the action of gravity, the positioning ball 671 returns to its lowest point to position the next AC gun.

[0064] Reference Figure 5 and Figure 6 To reduce the possibility of damage to the casing of the AC gun during the opening process of the expansion plate 613, a clamping assembly 66 is provided on the work frame 63. The clamping assembly 66 includes a mounting plate 661, which is mounted on the work frame 63 and located on the side of the first rack 6251 away from the second rack 6252. Two clamping rods 663 are mounted on the mounting plate 661. One end of the clamping rod 663 is rotatably connected to the mounting plate 661 via a shaft, and the other end is movably disposed. A sliding hole 6631 is provided through the side wall of the clamping rod 663 away from the mounting plate 661. The two clamping rods 663 are arranged crosswise. A sliding rod 6632 is horizontally inserted at the overlap of the two sliding holes 6631. A lifting rod 662 is vertically disposed at the end of the sliding rod 6632 away from the sliding hole 6631. The end of the lifting rod 662 away from the sliding rod 6632 is engaged and fixed to the worktable 64 via an extension rod. The movable end of the clamping rod 663 is horizontally engaged with a clamping block 664; when the AC gun is being calibrated, the two clamping blocks 664 are respectively clamped on the side walls on both sides of the AC gun. At this time, one clamping block 664 and the expansion plate 613 on the same side as the clamping block 664 jointly clamp the side wall of the AC gun.

[0065] When the piston rod of the drive cylinder 623 is fully retracted into the cylinder body, the slide rod 6632 is at its highest point, and the distance between the two clamping blocks 664 is greater than the size of the AC gun. The drive cylinder 623 is activated, and the worktable 64 and the second downward guide cone 624 descend synchronously. At this time, the lifting rod 662 drives the slide rod 6632 to descend vertically. The slide rod 6632 moves within the sliding hole 6631, causing the movable end of the clamping rod 663 to rotate downward with its pivot connected to the mounting plate 661 as the center, and the two clamping blocks 664 move closer to each other. Until the worktable 64 stops descending, the two expansion plates 613 are inserted into the mounting opening. At this time, the two clamping blocks 664 are located on both sides of the AC gun, and the distance between the two clamping blocks 664 is the standard distance after the left and right shells of the AC gun are expanded. At this time, the second downward guide cone 624 continues to descend, the two expansion plates 613 move away from each other, and the two expansion plates 613 expand the side walls on both sides of the AC gun to the sides. When the outer sides of the left and right shells of the AC gun are in contact with the clamping block 664, the second downward guide cone 624 moves down to the lowest distance, and the two expansion plates 613 expand the mounting port of the AC gun to the required size.

[0066] When the AC gun calibration is finished, the piston rod of the drive cylinder 623 retracts, and the two expansion plates 613 first move closer to each other, releasing the expansion of the AC gun sidewalls; then the worktable 64 rises, the expansion plates 613 move out of the AC gun mounting port, the slide rod 6632 moves upward and drives the movable end of the clamping rod 663 to rotate upward with its connection with the mounting plate 661 as the center, and the two clamping blocks 664 move away from each other, releasing the clamping of the left and right shells of the AC gun.

[0067] The implementation principle of Example 2 is as follows: The drive cylinder 623 drives the first rack 6251 to move downward, the first gear 6253 rotates counterclockwise, the second gear 6254 rotates clockwise, and the second rack 6252 moves downward; when the smooth surface of the second gear 6254 moves to the position of the second rack 6252, the second rack 6252 stops moving, the limit block 6255 is in contact with the top wall of the work frame 63, and the worktable 64 descends to the designated position. The first rack 6251 continues to descend, driving the second downward pressure guide cone 624 to be inserted between the two second anti-friction rollers 616 to separate the two spreading plates 613. When the correction is completed, the drive cylinder 623 drives the first rack 6251 and the second downward pressure guide cone 624 to move upward, at which time the two spreading plates 613 are reset under the action of the return spring 615. The first rack 6251 moves upward, at which time the first gear 6253 rotates clockwise and the second gear 6254 rotates counterclockwise. When the second gear 6254 meshes with the second rack 6252 again, it drives the second gear 6254 to rotate, causing the second rack 6252 to move upward, thereby driving the worktable 64 to reset.

[0068] When the piston rod of the drive cylinder 623 is fully retracted into the cylinder body, the positioning ball 671 is at its lowest position, and the distance between the two clamping blocks 664 is the farthest. The operator pushes the AC gun towards the positioning ball 671 until the front end of the AC gun contacts the positioning ball 671. The drive cylinder 623 starts, and the positioning ball 671 rises until it is in contact with the bottom wall of the positioning ring 674. The two clamping blocks 664 move closer to each other until the distance between the two clamping blocks 664 is the standard distance after the left and right shells of the AC gun are spread open. At the same time, the two spreading plates 613 correct the mounting port.

[0069] Example 3

[0070] The difference between this embodiment and embodiment 1 is that a spring is provided at the bottom of the workbench 64 to allow the workbench 64 to be suspended on the work frame 63. When the AC gun needs to be calibrated, the operator presses the workbench 64 with his hand to move the workbench 64 to the lowest point, and the two support plates 613 are inserted into the mounting port of the AC gun.

[0071] This application also discloses the production process of the AC gun filling production line, with reference to... Figure 7 and Figure 8 It includes the following steps:

[0072] Riveting: The operator installs the electronic components into the left shell 71 and right shell 72 of the AC gun 7, aligns the left shell 71 and right shell 72 in advance, and then puts the aligned left shell 71 and right shell 72 into the riveting mechanism 1. The riveting mechanism 1 applies uniform pressure to the left shell 71 and right shell 72 to rivet them together; an installation port 73 is left between the left shell 71 and right shell 72, and the outer shell of the AC gun 7 is initially installed.

[0073] Testing: The operator transfers the AC gun 7 to the testing platform of the testing mechanism 2 and tests the conductivity of the electronic components inside the casing of the AC gun 7 by conductivity testing.

[0074] Glue application: The operator installs the tested AC gun 7 onto the conveyor belt 5 and adjusts the angle of the AC gun 7 so that the mounting port 73 faces upwards and the line connecting the mounting port 73 and the gun nozzle is vertical. The conveyor belt 5 feeds the AC gun 7 into the glue application mechanism 3. The glue application head of the glue application mechanism 3 is vertically inserted into the housing of the AC gun 7 through the mounting port 73. As the glue application head is pulled out, the mixed glue is poured into the AC gun 7 until the internal cavity of the AC gun 7 is filled. The conveyor belt 5 then sends the glue-filled AC gun 7 out of the glue application mechanism 3.

[0075] Drying: Adjust the angle of the AC gun 7 so that the glue flows to the tail of the gun; the conveyor belt 5 sends the AC gun 7 into the drying mechanism 4, the drying mechanism 4 maintains the temperature in the drying tunnel, and the conveyor belt 5 drives the AC gun 7 to move slowly in the drying tunnel until the glue is initially dried; the conveyor belt 5 sends the AC gun 7 with the dried glue out of the drying tunnel.

[0076] Correction: The operator removes the AC gun 7 from the conveyor belt 5 and installs it on the fixture, adjusting the angle of the adjusting plate 651 and the position of the adjusting bracket 652 so that the mounting port 73 is directly below the spreading plate 613;

[0077] Assembly: Install the rear decorative panel 74 onto the housing of the AC gun 7 through the mounting port 73 to complete the potting assembly of the AC gun 7.

[0078] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
