Description

Technical Field

[0001] This application relates to the field of assembly technology, and in particular to a plug assembly line. Background Technology

[0002] Some plug connectors typically consist of a housing and a circuit board mounted inside the housing. Assembling the housing and the circuit board involves not only assembling the housing and placing the circuit board inside the housing, but also crimping and heat-melting the circuit board with the conductive components inside the housing. Therefore, assembling the plug connector requires frequent transfer between crimping machines, heat fusion machines, and laser melting machines.

[0003] Currently, it is usually necessary to allocate manpower to transfer between the above-mentioned multiple machines, and manpower also needs to be allocated to each machine for operation. Therefore, the manpower cost of completing the assembly of plug connectors is extremely high, the workflow is very complicated to coordinate, and the production efficiency is low. Summary of the Invention

[0075] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0076] See Figures 1 to 22 As shown, an embodiment of this application provides a plug assembly line for assembling plugs, such as automotive door plugs, wherein the plug includes a housing, a cover, and a circuit board.

[0077] The plug assembly line provided in this embodiment includes a hopper, a finished product tray 37, a first transfer tray 30, a second transfer tray 31, a housing loading flow line 1, a circuit board loading flow line 5, a crimping flow line 6, a hot melt flow line 7, a laser melting flow line 8, a functional testing flow line 91, and an airtightness testing flow line 92.

[0078] The first transfer tray 30 is used to carry the shell. Specifically, in order to improve the turnover efficiency of the shell, the first transfer tray 30 is used to carry multiple shells. That is, multiple shell positioning slots that match the shells are opened on the first transfer tray 30, and each shell positioning slot can accommodate and position a shell.

[0079] The second transfer tray 31 is used to carry circuit boards. Specifically, in order to improve the turnover efficiency of circuit boards, the second transfer tray 31 is used to carry multiple circuit boards. That is, multiple circuit board positioning slots adapted to the circuit boards are opened on the second transfer tray 31, and each circuit board positioning slot can accommodate and position a circuit board.

[0080] The housing loading flow line 1, circuit board loading flow line 5, crimping flow line 6, hot melt flow line 7 and laser melting flow line 8 are arranged sequentially from front to back, thereby conveying the first transfer tray 30 carrying the housing from the housing loading flow line 1 to the circuit board loading flow line 5, crimping flow line 6, hot melt flow line 7 and laser melting flow line 8 in sequence.

[0081] The circuit board loading line 5 can also transport the second transfer tray 31 carrying multiple circuit boards to the side of the first transfer tray 30, so that multiple circuit boards can be placed one by one on multiple housings on the first transfer tray 30 on the circuit board loading line 5, that is, the loading of circuit boards onto housings is completed to form the assembly to be pressed.

[0082] The crimping flow line 6 is disposed on the side of the crimping device 32, which includes existing crimping equipment. The component to be crimped is conveyed to the crimping flow line 6, i.e., to the side of the crimping device 32, along with the first transfer tray 30, thereby facilitating the crimping process of the component to be crimped by the crimping device 32 to form a component to be heat-fused. Specifically, the housing is provided with leads, and the circuit board is provided with hole-shaped pads corresponding to the leads. During the crimping process, the circuit board is crimped against the housing so that the leads deform and tighten within the hole-shaped pads.

[0083] The hot melt flow line 7 is located on the side of the hot melt device 33. The component to be hot melted is conveyed to the hot melt flow line 7, i.e., to the side of the hot melt device 33, along with the first transfer tray 30. This facilitates the hot melt treatment of the component to be hot melted by the hot melt device 33 to form the component to be fused. Specifically, after the crimping is completed, the tip of the pin protrudes relative to the hole-shaped pad. During the hot melt treatment, the tip of the pin melts and presses the circuit board against the hole-shaped pad.

[0084] The laser melting flow line 8 is located on the side of the laser melting device 34. The laser-melting assembly is conveyed to the hot melt flow line 7, i.e., to the side of the laser melting device 34, along with the first transfer tray 30, so that the laser-melting assembly can be laser-melted to form a plug. Specifically, the so-called "laser melting treatment" generally refers to ultrasonic welding. During the laser melting treatment, the housing and the circuit board are laser-melted to complete the positioning and connection between the two.

[0085] The functional test flow line 91 is set on the side of the functional test device 35. The plug is conveyed to the functional test flow line 91 along with the first transfer tray 30, that is, to the side of the functional test device 35, so that the plug can be functionally tested by the functional test device 35, thereby determining whether the assembled plug is functionally qualified, and the plug that passes the functional test is regarded as a functionally qualified plug.

[0086] The airtightness test flow line 92 is set on the side of the airtightness test device 36. The functional qualified plug is transported to the airtightness test flow line 92 along with the first transfer tray 30, that is, to the side of the airtightness test device 36, so that the functional qualified plug can be subjected to airtightness test by the airtightness test device 36, thereby determining whether the airtightness of the functional qualified plug is qualified. The functional qualified plug that passes the airtightness test is regarded as qualified plug, and the qualified plug is loaded into the finished product tray 37.

[0087] In this embodiment, see Figure 22 As shown, the silo mechanism includes a silo body and a loading and unloading assembly. The silo body is used to accommodate multiple layers of trays, wherein the trays can be any one of the first transfer tray 30, the second transfer tray 31, or the finished product tray 37.

[0088] The bin is used to hold stacked multi-layered trays and has a bottom opening so that the trays can enter and exit the bin relative to the bin through the bottom opening.

[0089] The loading and unloading assembly is located at the bottom opening. The loading and unloading assembly includes a first clamping part and a second clamping part that are spaced apart from each other. The first clamping part and the second clamping part can move away from each other to release the tray at the bottom opening, and the first clamping part and the second clamping part can move closer to each other to clamp the tray at the bottom opening.

[0090] Specifically, the silo mechanism can be used as a loading silo or a unloading silo. The working principle and process of the silo mechanism as a loading silo and unloading silo are described in the specific application scenarios below.

[0091] In this embodiment, see Figure 22 As shown, the material tray is conveyed by a lifting conveyor line, which includes a conveyor line body 540, a lifting component 541, a stop component 542, and a bearing positioning plate 543.

[0092] The conveyor body 540 can convey material trays along its own length. The conveyor body 540 has multiple lifting stations, and lifting components 541 are set at the lifting stations. The bearing positioning plate 543 is connected to the top of the lifting component 541. The lifting component 541 can drive the bearing positioning plate 543 to rise and fall relative to the conveyor body 540. Specifically, lifting components 541 are provided on both sides of the width direction of the conveyor body 540, and the tops of the lifting components 541 on both sides of the conveyor body 540 are connected to the bearing positioning plate 543. The specific structure of the lifting component 541 is not limited, as long as it can realize the lifting and lowering drive of the bearing positioning plate 543 without affecting the normal conveying function of the conveyor body 540. For example, the lifting component 541 includes a support base and a lifting drive cylinder connected to the support base, and the bearing positioning plate 543 is installed on the support base.

[0093] Furthermore, the lifting member 541 can drive the bearing positioning plate 543 to rise and fall relative to the conveyor body 540 between a first position and a second position. Specifically, the "first position" means that when the bearing positioning plate 543 is in the first position, the upper surface of the bearing positioning plate 543 is flush with the upper surface of the conveyor body 540, so that the material tray conveyed by the conveyor body 540 can be conveyed onto the bearing positioning plate 543. The "second position" means that when the bearing positioning plate 543 is in the second position, the height difference between the lower surface of the bearing positioning plate 543 and the upper surface of the conveyor body 540 is not less than the height of the material tray. Thus, when the bearing positioning plate 543 of a certain lifting station is driven to the second position by the lifting member 541, a clearance channel can be formed between the bearing positioning plate 543 and the conveyor body 540. The clearance channel allows the material tray to pass through, and the material tray passing through the clearance channel can continue to be conveyed backward, for example, to the next lifting station or the next flow line.

[0094] The bearing positioning plate 543 is used to support and position the material tray. The bearing positioning plate 543 includes a bearing plate and a positioning suction head set on the bearing plate. When the material tray is located on the bearing plate, the positioning suction head can adsorb and position the material tray to prevent the material tray from moving relative to the bearing plate.

[0095] The stop member 542 is vertically and flexibly disposed behind the bearing positioning plate 543. When the stop member 542 is raised and the bearing positioning plate 543 is in the first position, the stop member 542 acts as a stop for the material tray, causing the material tray to remain on the bearing positioning plate 543. When the stop member 542 is lowered and the bearing positioning plate 543 is in the first position, the stop member 542 releases the material tray, allowing the material tray to continue to flow backward under the conveying action of the conveyor body 540.

[0096] In the optional solutions of this embodiment, see Figures 1 to 4As shown, the lifting conveyor line of the housing loading flow line 1 is defined as the first lifting conveyor line 11. The housing loading flow line 1 also includes a first pick-and-transfer mechanism 12. Specifically, the housing loading flow line 1 also includes a first machine base 15. The first lifting conveyor line 11 and the first pick-and-transfer mechanism 12 are both set on the first machine base 15. The first lifting conveyor line 11 is used to convey the first transfer tray 30 containing multiple housings. The first lifting conveyor line 11 has multiple first lifting stations to simultaneously perform housing loading operations on the housings in the multiple first transfer trays 30, thereby improving the housing loading efficiency.

[0097] The feeding end of the first lifting conveyor line 11 is provided with a first feeding bin 10. The first feeding bin 10 is used to store multiple stacked empty first transfer trays 30. The first clamping component and the second clamping component are far apart from each other, so that the bottommost first transfer tray 30 at the bottom opening of the first feeding bin 10 is released to the first lifting conveyor line 11, thereby completing the feeding of the first transfer tray 30 to the first lifting conveyor line 11.

[0098] Each first lifting station is equipped with a tray scanning component 46, which is used to scan the identification code of the first transfer tray 30 that is stationed at the first lifting station to identify the first transfer tray 30.

[0099] The first picking and transferring mechanism 12 can sort out unqualified shells from the first transfer tray 30 on the first lifting conveyor line 11. Specifically, the first machine base 15 is also provided with an unqualified product tray 48 for accommodating unqualified shells. The first picking and transferring mechanism 12 is provided with an upper surface detection camera 40. When the first picking and transferring mechanism 12 picks up the shells in the first transfer tray 30, the quality of the upper surface of the shell can be detected by the upper surface detection camera 40. If the upper surface quality is unqualified, the unqualified shell is directly placed in the unqualified product tray 48.

[0100] In this embodiment, to perform three-dimensional multi-angle detection of the surface quality of the shell, see [reference needed]. Figure 4 As shown, the housing loading flow line 1 also includes a housing detection module 14, which includes at least five housing detection cameras 140. For example, the housing detection module 14 includes five, six or more housing detection cameras 140. In order to save costs, the number of housing detection cameras 140 in the housing detection module 14 is set to five.

[0101] At least five housing inspection cameras 140 are distributed on the five surfaces of the hexahedron excluding the top surface and enclose a housing inspection space. Each housing inspection camera 140 is facing the housing inspection space to take pictures. Specifically, if the quality of the top surface of the housing is found to be qualified after inspection by the top surface inspection camera 40, then the first pick-and-transfer mechanism 12 transports the housing to the housing inspection space so that the other surfaces of the housing can be inspected in multiple directions by the housing inspection module 14.

[0102] Understandably, the housing detected by the housing detection module 14 and the upper surface detection camera 40 can be returned to the first transfer tray 30 by the first pick-up and transfer mechanism 12. Conversely, if it fails the inspection, it is placed in the non-conforming tray 48 on the first machine 15.

[0103] Furthermore, in order to ensure that the housing detection module 14 can perform no blind spot detection on the housing, the first pick-up and transfer mechanism 12 can be configured to include a first robotic arm, a first rotation drive component 120 and a first adsorption component.

[0104] The first adsorption component is used to adsorb the upper surface of the shell, and the first robotic arm is used to drive the first adsorption component with the shell adsorbed to move between the first transfer tray 30, the shell detection module 14 and the non-conforming product tray 48 on the first machine table 15.

[0105] The first robotic arm is rotatably connected to the first adsorption component, and the first rotation drive component 120 is connected to the first adsorption component and can drive the first adsorption component to rotate. Thus, the housing can be rotated through the first adsorption component, which increases the rotational degree of freedom compared to the first robotic arm, allowing the housing detection camera 140 to capture and detect the housing from more angles.

[0106] The first pick-up and transfer mechanism 12 also includes a first lifting drive component 122, and the first adsorption component includes a first mounting base 123 and a plurality of first suction heads 121, which are used to simultaneously adsorb and detect the surfaces of a plurality of housings in a one-to-one correspondence.

[0107] Multiple first suction heads 121 are slidably connected to the first mounting base 123 along the suction direction. The first lifting drive component 122 can drive the multiple suction heads to slide relative to the first mounting base 123 along the suction direction. Thus, under the drive of the first lifting drive component 122, the multiple adsorbed shells can be inserted deeper into the shell detection space, improving the surface detection accuracy.

[0108] Optionally, the number of first lifting stations, the number of first picking and transferring mechanisms 12, the number of housing detection modules 14, and the number of housing defective sheet trays are all multiple and equal, so that they can be transferred between the same first lifting station, the same housing detection module 14, and the same defective sheet tray 48 through the same first picking and transferring mechanism 12.

[0109] In the optional solutions of this embodiment, see Figure 5 and Figure 6 As shown, the lifting conveyor line defining the circuit board loading flow line 5 includes a second lifting conveyor line 53 and a third lifting conveyor line 54. The circuit board loading flow line 5 also includes a second pick-and-transfer mechanism 52. Specifically, the housing loading flow line 1 also includes a second machine base 50. The second lifting conveyor line 53, the third lifting conveyor line 54 and the second pick-and-transfer mechanism 52 are all located on the second machine base 50.

[0110] The second lifting conveyor line 53 is located behind the first lifting conveyor line 11 and is used to convey a first transfer tray 30 containing multiple shells that have passed surface inspection. The second lifting conveyor line 53 has multiple second lifting stations to simultaneously perform circuit board loading operations on the shells in the multiple first transfer trays 30, thereby improving the circuit board loading efficiency. Each second lifting station is equipped with a tray scanning component 46, which scans the identification code of the first transfer tray 30 that is stationed at the second lifting station to identify the first transfer tray 30.

[0111] The third lifting conveyor line 54 is arranged side-by-side with the second lifting conveyor line 53 and is used to transport the second transfer tray 31. The second transfer tray 31 is used to hold circuit boards. The third lifting conveyor line 54 has multiple third lifting stations, which are arranged one-to-one with the multiple second lifting stations. Each third lifting station is equipped with a tray scanning component 46, which is used to scan the identification code of the second transfer tray 31 that is stopped at the third lifting station to determine the identity of the second transfer tray 31.

[0112] Specifically, the feeding end of the third lifting conveyor line 54 is provided with a second feeding bin 55, which is used to store multiple stacked controlled second transfer trays 31, so that the feeding operation of the second transfer trays 31 to the third lifting conveyor line 54 can be completed through the second feeding bin 55. The discharging end of the third lifting conveyor line 54 is provided with a second discharging bin 56. When the second transfer tray 31 is conveyed by the third lifting conveyor line 54 to the bottom opening of the second discharging bin 56, the second transfer tray 31 is clamped and lifted by the first clamping part and the second clamping part, so that the second transfer tray 31 can be loaded into the second discharging bin 56.

[0113] The second pick-and-transfer mechanism 52 can sort out defective circuit boards from the second transfer tray 31 on the third lifting conveyor line 54. Specifically, the second machine 50 is also equipped with a defective product tray 48 for accommodating defective circuit boards. The second pick-and-transfer mechanism 52 is equipped with an upper surface inspection camera 40. When the second pick-and-transfer mechanism 52 picks up the circuit board in the second transfer tray 31 at the third lifting station of the third lifting conveyor line 54, the second pick-and-transfer mechanism 52 can inspect the circuit board through the upper surface inspection camera 40. If the circuit board is defective, the second pick-and-transfer mechanism 52 puts the defective circuit board into the defective product tray 48.

[0114] In addition, the first machine 15 is equipped with a lower camera 43 for inspecting the lower surface of the circuit board. If the upper surface of the circuit board is qualified, the circuit board is moved from the second transfer tray 31 on the third lifting conveyor line 54 to above the lower camera 43. The lower camera 43 faces upward and inspects the lower surface of the circuit board. If the lower surface is also qualified, the second pick-and-transfer mechanism 52 places the circuit board with qualified upper and lower surfaces onto the housing in the first transfer tray 30 on the second lifting conveyor line 53, so as to assemble the qualified circuit board with the qualified housing to form the assembly to be pressed. Conversely, if the lower surface is unqualified, the second pick-and-transfer mechanism 52 also puts it into the unqualified product tray 48 on the second machine 50.

[0115] In this embodiment, the number of second lifting stations, the number of third lifting stations, the number of second pick-and-transfer mechanisms 52, and the number of defective product trays 48 are all multiple and equal, so that they can be transferred between the same second lifting station, the same third lifting station, and the same defective product tray 48 through the same second pick-and-transfer mechanism 52.

[0116] In the optional solutions of this embodiment, see Figures 7 to 9 As shown, the lifting conveyor line of the crimping conveyor line 6 is defined as the fourth lifting conveyor line 60. The crimping conveyor line 6 also includes a third pick-and-transfer mechanism 61. Specifically, the crimping conveyor line 6 also includes a third machine base 62. The fourth lifting conveyor line 60 and the third pick-and-transfer mechanism 61 are both located on the third machine base 62. The fourth lifting conveyor line 60 is located behind the second lifting conveyor line 53 and is used to convey the first transfer tray 30 containing the components to be crimped. The fourth lifting conveyor line 60 has multiple fourth lifting stations to simultaneously crimp the components to be crimped in multiple first transfer trays 30, thereby improving the crimping efficiency of the components to be crimped.

[0117] Each fourth lifting station is equipped with a tray scanning component 46, which is used to scan the identification code of the first transfer tray 30 that is stationed at the fourth lifting station to identify the first transfer tray 30.

[0118] The side of the fourth lifting conveyor line 60 is used to install the crimping device 32. The third pick-up and transfer mechanism 61 can transfer the component to be crimped between the first transfer tray 30 on the fourth lifting conveyor line 60 and the crimping device 32, so that the component to be crimped is formed into a component to be heat-melted after being crimped by the crimping device 32, and the component to be heat-melted is placed back into the first transfer tray 30.

[0119] A lower camera 43 is installed on the side of the fourth lifting conveyor line 60. Specifically, the lower camera 43 is installed on the side of the fourth lifting conveyor line 60 facing the crimping device 32. During the process of the third pick-up and transfer mechanism 61 transferring the component to be crimped to the crimping device 32, the lower camera 43 positions the component to be crimped, thereby determining which suction heads of the third pick-up and transfer mechanism 61 are occupied by the picked-up component, so that the crimped component to be heat-melted can be taken out from the crimping device 32 through the unoccupied suction heads. Before taking out the component to be heat-melted, it is first re-inspected by the re-inspection camera 41 on the third pick-up and transfer mechanism 61. After the re-inspection confirms that the crimping is qualified, the component to be heat-melted is then taken out.

[0120] After the component to be heat-melted is removed, the upper camera 42 on the pressing device 32 positions the pressing fixture 320 and the component to be heat-melted, so that the picked-up component to be heat-melted is accurately placed into the pressing device 32, and then the pressing device 32 performs the pressing process on the component to be heat-melted. Then, the third picking and transferring mechanism 61 puts the component to be heat-melted back into the first transfer tray 30 on the fourth lifting conveyor line 60.

[0121] There are multiple crimping devices 32, and correspondingly, there are multiple crimping flow lines 6, which are arranged sequentially from front to back. In order to improve the sorting efficiency of defective products, a defective product sorting mechanism 47 is set only at the rear end of the last crimping flow line 6, that is, the discharge end, and a defective product tray 48 is set on the third machine 62. When the first transfer tray 30 carrying the components to be heat-melted is conveyed to the defective product sorting mechanism 47, the components that fail the re-inspection can be taken out by the defective product sorting mechanism 47 and placed in the defective product tray 48 on the third machine 62.

[0122] In the optional solutions of this embodiment, see Figures 10 to 14As shown, the lifting conveyor line of the hot melt flow line 7 is defined as the fifth lifting conveyor line 70. The hot melt flow line 7 also includes a fourth pick-and-transfer mechanism 71. Specifically, the hot melt flow line 7 also includes a fourth machine base 72. The fifth lifting conveyor line 70 and the fourth pick-and-transfer mechanism 71 are both set on the fourth machine base 72. The fifth lifting conveyor line 70 is set behind the fourth lifting conveyor line 60. The fifth lifting conveyor line 70 is used to convey the first transfer tray 30 containing the components to be hot melted. The fifth lifting conveyor line 70 has multiple fifth lifting stations to simultaneously hot melt the components to be hot melted in multiple first transfer trays 30, thereby improving the hot melt efficiency.

[0123] Each fifth lifting station is equipped with a tray scanning component 46, which is used to scan the identification code of the first transfer tray 30 that is stationed at the fifth lifting station to identify the first transfer tray 30.

[0124] The side of the fifth lifting conveyor line 70 is used to install the hot-melt device 33. The fourth pick-up and transfer mechanism 71 can transfer the component to be hot-melted between the first transfer tray 30 on the fifth lifting conveyor line 70 and the hot-melt device 33, so that the component to be hot-melted is formed into a cover assembly after being hot-melted by the hot-melt device 33, and the cover assembly is placed back into the first transfer tray 30.

[0125] A lower camera 43 is provided on the side of the fifth lifting conveyor line 70. Specifically, the lower camera 43 is provided on the side of the fifth lifting conveyor line 70 facing the hot-melt device 33. During the process of the fourth picking and transferring mechanism 71 transferring the component to be hot-melted to the hot-melt device 33, the lower camera 43 positions the component to be hot-melted picked up, thereby determining which suction heads of the fourth picking and transferring mechanism 71 are occupied by the picked component to be hot-melted, so that the component to be capped after hot-melting can be taken out from the hot-melt device 33 through the unoccupied suction heads.

[0126] The hot melt fixture 330 of the hot melt device 33 includes a hot melt fixture body 3300 and a flip-up cover 3301. The flip-up cover 3301 can be flipped relative to the hot melt fixture body 3300, thereby pressing and positioning the components to be hot melted on the hot melt fixture 330 through the flip-up cover 3301.

[0127] The fifth lifting conveyor line 70 is equipped with a flipping mechanism 73 on the side near the hot melt flow line 7. Before taking out the cover assembly to be installed, the flipping mechanism 73 is used to flip and open the fliptable cover 3301. Then, the re-inspection camera 41 on the fourth picking and transfer mechanism 71 is used to re-inspect it. After the re-inspection confirms whether the laser melting is qualified, the cover assembly to be installed is taken out.

[0128] After the component to be installed is removed, the upper camera 42 on the hot-melt device 33 positions the hot-melt fixture 330 and the component to be installed, so that the picked-up component to be installed is accurately placed into the pressing device 32. Then, the flip-top cover 3301 is flipped and closed by the flipping mechanism 73, and the component to be pressed is then pressed by the pressing device 32. Then, the third picking and transferring mechanism 61 puts the component to be installed back into the first transfer tray 30 on the fourth lifting conveyor line 60.

[0129] Among them, see Figure 13 As shown, the flipping mechanism 73 can be any structure capable of flipping the fliptable cap 3301. As an example, the flipping mechanism 73 includes a flipping drive member 730, a feed drive member 731, and a clamping member 732.

[0130] The clamping member 732 is used to clamp the flip-up cap 3301. The clamping member 732 is disposed on the feed drive member 731. The feed drive member 731 can drive the clamping member 732 to move closer to or away from the flip-up cap 3301. The feed drive member 731 is disposed on the flip drive member 730. The flip drive member 730 can drive the feed drive member 731 and the clamping member 732 to flip the flip-up cap 3301.

[0131] There are multiple hot-melt devices 33, and correspondingly, there are multiple hot-melt flow lines 7, which are arranged sequentially from front to back. In order to improve the sorting efficiency of defective products, a defective product sorting mechanism 47 is set only at the rear end of the last hot-melt flow line 7, that is, the discharge end, and a defective product tray 48 is set on the fourth machine 72. When the first transfer tray 30 carrying the cover assembly to be installed is transported to the defective product sorting mechanism 47, the cover assembly that fails the re-inspection can be taken out by the defective product sorting mechanism 47 and placed in the defective product tray 48 on the fourth machine 72.

[0132] In the optional solutions of this embodiment, see Figures 16 to 17 As shown, the lifting conveyor line of the laser melting line 8 is defined as the sixth lifting conveyor line 80. The hot melting line 7 also includes a fifth machine 82 and a fifth pick-and-transfer mechanism 85, a sixth pick-and-transfer mechanism 81 and a cover supply mechanism 84 set on the fifth machine 82. Specifically, the sixth lifting conveyor line 80 is set behind the fifth lifting conveyor line 70. The sixth lifting conveyor line 80 is used to transport the first transfer tray 30 containing the cover assembly to be installed. The sixth lifting conveyor line 80 has multiple sixth lifting stations to simultaneously perform laser melting on the cover assemblies to be installed in multiple first transfer trays 30, thereby improving the laser melting efficiency.

[0133] Each sixth lifting station is equipped with a tray scanning component 46, which is used to scan the identification code of the first transfer tray 30 that is stopped at the sixth lifting station to identify the first transfer tray 30.

[0134] The side of the sixth lifting conveyor line 80 is used to install the laser melting device 34. The fifth pick-up and transfer mechanism 85 can transfer the assembly to be installed from the sixth lifting conveyor line 80 to the laser melting device 34, and can put the assembly to be tested after laser melting back into the first transfer tray 30 on the sixth lifting conveyor line.

[0135] A lower camera 43 is provided on the side of the sixth lifting conveyor line 80. Specifically, the lower camera 43 is provided on the side of the sixth lifting conveyor line 80 facing the laser melting device 34. During the process of the fifth pick-up and transfer mechanism 85 transferring the cover assembly to be installed to the laser melting device 34, the lower camera 43 positions the cover assembly to be installed picked up, thereby determining which suction heads of the fourth pick-up and transfer mechanism 71 are occupied by the picked-up cover assembly, so that the laser-melted assembly to be tested can be taken out from the laser melting device 34 through the unoccupied suction heads.

[0136] After the component to be tested is removed, the upper camera 42 on the laser melting device 34 positions the laser melting fixture and the component to be covered, so that the picked-up component to be inspected is accurately placed into the laser melting fixture. Then, the fifth picking and transferring mechanism 85 puts the component to be tested back into the first transfer tray 30 on the sixth lifting conveyor line 80.

[0137] The cover supply mechanism 84 is used to supply the cover to the sixth pick-up and transfer mechanism 81. The sixth pick-up and transfer mechanism 81 can take the cover out from the cover supply mechanism 84 and place it on the cover assembly to be installed on the laser melting device 34 to form the laser melting assembly. Then the laser melting device 34 can perform laser melting on the laser melting assembly to obtain the assembly to be tested.

[0138] Among them, see Figure 16 As shown, the cover supply mechanism 84 includes a vibratory feeder 840 and a cover conveyor belt 841. The cover conveyor belt 841 is arranged side by side on the side of the sixth lifting conveyor line 80. The vibratory feeder 840 can vibrate multiple covers, thereby continuously outputting the covers one by one.

[0139] The vibratory feeder 840 is provided at the feed end of the cover conveyor belt 841 so that the cover conveyor belt 841 can transport the covers in rows. The sixth pick-up and transfer mechanism 81 is provided at the discharge end of the cover conveyor belt 841 so that the sixth pick-up and transfer mechanism 81 can pick up, transfer and place a single cover on the cover assembly to be installed.

[0140] See Figure 17As shown, the sixth pick-up and transfer mechanism 81 includes a sixth transfer body, a sixth rotation drive component 862, and a sixth adsorption component 863.

[0141] The sixth rotation drive component 862 is connected between the sixth transport body and the sixth adsorption assembly 863. The sixth rotation drive component 862 can drive the sixth adsorption assembly 863 to rotate vertically, so that the cover adsorbed by the sixth adsorption assembly 863 rotates to a positive orientation. Specifically, the cover has markings to distinguish between the positive and negative sides. Before assembling the cover with the assembly to be installed, the cover needs to be adjusted to a positive orientation to ensure correct assembly. However, the cover picked up by the sixth adsorption assembly 863 may not be in a positive orientation. Therefore, the sixth rotation drive component 862 drives the sixth adsorption assembly 863 to rotate the cover until it reaches a positive orientation before transporting and placing the cover on the assembly to be installed. To facilitate the detection of the cover's orientation, a cover detection camera 854 is provided on the sixth transport body, located on the side of the sixth adsorption assembly 863.

[0142] Optionally, in order to save space and reduce the equipment footprint, the fifth picking and transferring mechanism 85 can be configured to transfer via a robotic arm, and the sixth transferring body can transfer via a linear module. Specifically, the sixth transferring body includes a first linear transfer module 860 and a second linear transfer module 861, a sixth rotation drive component is disposed between the first linear transfer module 860 and the sixth adsorption component, and the first linear transfer module 860 is disposed between the second linear transfer module 861.

[0143] There are multiple laser melting devices 34, and correspondingly, there are multiple laser melting flow lines 8, which are arranged sequentially from front to back. In order to improve the sorting efficiency of defective products, a defective product sorting mechanism 47 is set only at the rear end of the last laser melting flow line 8, that is, the discharge end, and a defective product tray 48 is set on the fifth machine 82. When the first transfer tray 30 carrying the components to be laser melted is transported to the defective product sorting mechanism 47, the components that fail the re-inspection can be taken out by the defective product sorting mechanism 47 and placed in the defective product tray 48 on the fifth machine 82.

[0144] In this embodiment, the crimping flow line 6, the hot melt flow line 7, the laser melting flow line 8, the functional test flow line 91, and the airtightness test flow line 92 are all equipped with sample trays 44. The sample trays 44 are used to place samples of intermediate products produced by the device corresponding to each flow line, especially the sample of the first intermediate product produced in the initial stage of the device's startup.

[0145] In this embodiment, see Figure 14As shown, to save space occupied by the defective product sorting mechanism 47, the defective product sorting mechanism includes a first linear module 470, a second linear module 471, a lifting drive module, and a defective product adsorption component 472. The defective product adsorption component 472 includes multiple suction heads, which can simultaneously pick up multiple defective products. The defective product adsorption component 472 is set on the first linear module 470 via the lifting drive module, and the first linear module 470 is set on the second linear module 471. Thus, the first linear module 470 and the second linear module 471 can drive the defective product adsorption component 472 to move along the width and length directions of the conveyor line body. The lifting drive module can drive the defective product adsorption component 472 to lift and lower the defective products.

[0146] In the optional solutions of this embodiment, see Figures 18 to 21 As shown, the plug assembly line also includes a testing flow line group located after the laser melting flow line 8. The testing flow line group can test the components to be tested and load the qualified components into the finished product tray as qualified plugs and output them as finished plugs. At the same time, the unqualified components to be tested are loaded into the unqualified product tray 48 as unqualified plugs.

[0147] The test flow line group includes a functional test flow line 91 located on the side of the functional test device 35 and an airtightness test flow line 92 located on the side of the airtightness test device 36. The functional test device 35 performs functional testing on the component to be tested as a component to be functionally tested, and the airtightness test device 36 performs airtightness testing on the component to be functionally tested that has passed the functional test.

[0148] In this embodiment, see Figures 18 to 19 As shown, the lifting conveyor line of the functional test flow line 91 is defined as the seventh lifting conveyor line 910. The functional test flow line 91 also includes a sixth machine 913, a seventh pick-and-transfer mechanism 911, and a defective product tray 48. The seventh lifting conveyor line 910 and the seventh pick-and-transfer mechanism 911 are both set on the sixth machine 913. Specifically, the seventh lifting conveyor line 910 is set behind the sixth lifting conveyor line 80. The seventh pick-and-transfer mechanism 911 can transfer the component to be functionally tested from the seventh lifting conveyor line 910 to the functional test device 35 for functional testing, and can put the component to be functionally tested that has passed the functional test back into the first transfer tray 30 on the seventh lifting conveyor line 910 as the component to be airtightness tested. At the same time, the component to be tested that has failed the functional test is put into the defective product tray 48 on the sixth machine 913.

[0149] The seventh pick-and-transfer mechanism 911 also includes a seventh robotic arm and a seventh adsorption assembly 912. The seventh adsorption assembly 912 is disposed on the seventh robotic arm. See [link to documentation]. Figure 19As shown, the seventh adsorption component 912 includes two sets of suction head groups 9120, each set of suction head groups 9120 including multiple seventh suction heads with adjustable spacing. In one set of suction head groups 9120, the multiple seventh suction heads are used to adsorb multiple components to be tested for airtightness in a one-to-one correspondence, while in the other set of suction head groups 9120, the multiple seventh suction heads are used to adsorb multiple components to be tested for airtightness that have already undergone functional testing in a one-to-one correspondence.

[0150] To make the spacing between the multiple seventh suction heads in each suction head group 9120 adjustable, the multiple seventh suction heads can be installed on independent seats. Each seat is movably connected to the frame of the seventh adsorption assembly 912. The frame is provided with a guide groove, and the seat is provided with a guide post extending into the guide groove. By driving the seat to move and causing the guide post to move along the guide groove, the spacing between the multiple seventh suction heads can be adjusted.

[0151] Since the distribution of the components to be tested for airtightness on the seventh lifting conveyor line 910 is random after the defective products are removed, when multiple components to be tested for airtightness are simultaneously adsorbed by the seventh adsorption component 912, the spacing of the multiple seventh suction heads in the suction head group 9120 is adjustable. This allows the seventh adsorption component 912 to adjust the spacing of the seventh suction heads in the suction head group 9120 according to the distribution position of the components to be tested for airtightness, so that the picking up of the components to be tested for airtightness is not affected by the randomness of the distribution position of the components to be tested for airtightness.

[0152] In this embodiment, see Figure 20 and Figure 21 As shown, the lifting conveyor line of the airtightness test flow line 92 is defined as the eighth lifting conveyor line 920. The airtightness test flow line 92 also includes the seventh machine 923 and the ninth lifting conveyor line 921 and the eighth pick-up and transfer mechanism 922 installed on the seventh machine 923.

[0153] Specifically, the eighth lifting conveyor line 920 is located behind the seventh lifting conveyor line 910, and the ninth lifting conveyor line 921 is located on the side of the eighth lifting conveyor line 920. The ninth lifting conveyor line 921 is used to transport the finished product tray 37. The eighth pick-up and transfer mechanism 922 can transfer the components to be tested for air tightness on the eighth lifting conveyor line 920 to the air tightness testing device 36 for air tightness testing, and can insert the plugs that pass the air tightness test into the finished product tray 37 on the ninth lifting conveyor line 921.

[0154] Because the entrance to the airtightness testing device 36 is relatively narrow, if multiple airtightness testing components 39 are transported in a side-by-side, spaced-apart arrangement along their width, they will not be able to pass through the entrance. To ensure that the multiple airtightness testing components 39 picked up by the eighth pick-up and transfer mechanism 922 can smoothly pass through the entrance of the airtightness testing device 36, see [reference needed]. Figure 21 As shown, the eighth pick-and-transfer mechanism 922 includes an eighth six-axis manipulator and an eighth adsorption assembly 925. The eighth adsorption assembly 925 is disposed on the eighth six-axis manipulator and includes a base, a mounting base, a first driving component, a plurality of eighth rotation driving components 927 and a plurality of eighth suction heads 926.

[0155] The reason for setting the robotic arm of the eighth adsorption component 925 as a six-axis robotic arm is to improve the flexibility of the eighth adsorption component 925 driven by the eighth six-axis robotic arm.

[0156] Multiple eighth suction heads 926 are connected to the mounting base via multiple eighth rotation drive components 927. The multiple eighth rotation drive components 927 can drive the multiple eighth suction heads 926 to rotate relative to the mounting base around their own axes in a corresponding manner. Thus, the multiple eighth suction heads 926 pick up the multiple airtightness test components 39 in an attitude in which they are arranged side by side at intervals along their width direction. Before the multiple airtightness test components 39 need to pass through the inlet of the airtightness test device 36, the multiple eighth rotation drive components 927 drive the multiple eighth suction heads 926 to rotate around their own axes, so as to rotate the multiple airtightness test components 39 to a attitude in which they are arranged side by side at intervals along their own thickness direction. This reduces the inlet width required by the multiple airtightness test components 39, and thus allows them to pass smoothly through the inlet of the airtightness test device 36.

[0157] The first driving member is connected between the mounting base and the base, and the first driving member can drive the mounting base to reciprocate relative to the base in a direction perpendicular to the axis of the eighth suction head 926.

[0158] Thus, after the multiple airtightness test components 39 picked up by the eighth pick-up and transfer mechanism 922 enter the airtightness test device 36, the multiple eighth rotation drive components 927 drive the multiple eighth suction heads 926 to rotate, so that the multiple airtightness test components 39 return to the posture of being arranged side by side at intervals along their own width direction, in preparation for being placed in the airtightness test station.

[0159] Then, the first driving component drives the mounting base to lower multiple airtightness test components 39 relative to the airtightness test station until they are installed on the airtightness test components 39.

[0160] It is understandable that the step of removing the airtightness test component 39 after the test is completed is the reverse of the process described above, and will not be elaborated here.

[0161] After removing the airtightness test-tested component 39, place the qualified airtightness test-tested component 39 into the finished product tray 37 on the ninth lifting conveyor line 921 until the tray is full. Then, it can be conveyed to its discharge end through the ninth lifting conveyor line 921. Place the unqualified airtightness test-tested component 39 back into the first transfer tray 30 on the eighth lifting conveyor line 920.

[0162] In order to achieve continuous supply of empty finished product trays 37, a third feeding bin 924 is set at the feeding end of the ninth lifting conveyor line 921. The third feeding bin 924 is used to store multiple empty finished product trays 37.

[0163] In this embodiment, the crimping flow line 6, the hot melt flow line 7, and the laser melting flow line 8 are all equipped with an ion air cleaning mechanism 45. The ion air cleaning mechanism 45 can blow ion air to clean the components in the first transfer tray 30 before and after crimping, before and after hot melting, and before and after laser melting.
