Description

Technical Field

[0001] This utility model relates to the field of radar manufacturing technology, and in particular to an automated intelligent radar production system. Background Technology

[0002] The automated intelligent production line for millimeter-wave radar is mainly used for radar sensor assembly and testing. The automated intelligent production line for millimeter-wave radar needs to complete the automatic assembly of radar components first. Its assembly process usually includes: welding breathable membrane, PCBA programming and testing, applying thermal conductive adhesive, riveting heat sink frame, PCBA assembly, antenna radome assembly, etc. After the assembly is completed, the assembled radar needs to be tested to see if it can meet the usage standards. The testing steps usually include high temperature aging test, airtightness test, laser marking, etc.

[0003] Existing laser marking mechanisms not only include a laser marking unit for marking, but also a flipping component. The gripper first places the radar on the flipping component and flips it to the marking surface. Then, the gripper places it on the radar positioning plate for marking. This results in a longer marking time, requiring two transfers through the gripper, which takes up a lot of time and leads to a slow production cycle. It is also prone to large placement errors. Utility Model Content

[0004] The purpose of this invention is to provide an automated intelligent production system for radar, which solves the problems of slow production cycle and large placement errors of the laser marking device during marking and testing after automatic radar assembly.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] Radar automated intelligent production system, which includes:

[0007] An assembly line configured to assemble radar shapes;

[0008] A test line, located downstream of the assembly line, includes a laser marking device comprising:

[0009] The flipping mechanism includes a lifting drive component, a flipping drive component is provided at the output end of the lifting drive component, and a vacuum adsorption disk is provided at the output end of the flipping drive component. The vacuum adsorption disk is used to adsorb and fix the radar.

[0010] A marking mechanism configured to mark the radar;

[0011] The moving mechanism includes a moving drive and a platform. The platform is used to support and fix the radar. The moving drive can drive the platform to move between the vacuum adsorption disk and the marking mechanism.

[0023] In some embodiments, a positioning monitoring element is provided on the first conveyor belt, the positioning monitoring element is signal-connected to the rotating assembly, and the positioning monitoring element monitors the radar position of the first conveyor belt.

[0024] In some embodiments, the test line further includes an airtightness testing device and a dark box testing device. The airtightness testing device is located upstream of the laser marking device and is used to detect the airtightness of the radar. The dark box testing device is located downstream of the laser marking device and is used to perform dark box testing on the radar.

[0025] The beneficial effects of this utility model are:

[0050] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0051] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; 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; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0052] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0053] In the description of this embodiment, the terms "upper," "lower," "left," and "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0054] like Figures 1 to 14 As shown, this application provides an automated intelligent production system for radar, which includes an assembly line and a testing line. The assembly line is configured to assemble a radar 300. The assembly line includes a waterproof and breathable membrane welding device 10, a heat sink frame feeding device 20, a PCBA programming and FCT testing device 30, a thermally conductive adhesive coating device 40, a heat sink frame riveting device 50, a PCBA pressing device 60, and an antenna radome welding device 70 arranged sequentially. The waterproof and breathable membrane welding device 10 is used to weld a waterproof and breathable membrane onto the lower shell. The membrane is then transferred to the heat sink frame feeding device 20, where the heat sink is placed into the corresponding heat sink frame placement slot inside the lower shell. The membrane is then transferred... The PCBA programming and FCT testing device 30 programs the PCBA board and places the programmed PCBA into the corresponding PCBA placement slot in the lower housing. It then flows to the thermally conductive adhesive coating device 40, where thermally conductive adhesive is applied to the heat sink frame and the lower housing. Next, it flows to the heat sink frame riveting device 50, where the lower housing and heat sink frame are moved into the hot air cold riveting assembly for assembly. It then flows to the PCBA pressing device 60, where the PCBA board is pressed to the lower housing. Finally, it flows to the radome welding device 70, where the radome is welded to the lower housing, completing the assembly of the radar 300. The assembled radar 300 is then transferred to the testing line for testing. It should be noted that all devices within the assembly line are existing technologies, and their specific structures will not be described in detail.

[0055] like Figure 1 As shown, the test line is located downstream of the assembly line. The test line includes an aging device 80, an airtightness testing device 90, a laser marking device 100, and a dark box testing device 200. The aging device 80 is located downstream of the radome welding device 70. The airtightness testing device 90 is located upstream of the laser marking device 100 and downstream of the aging device 80. The dark box testing device 200 is located downstream of the laser marking device 100. The airtightness testing device 90 is used to detect the airtightness of the radar 300, and the dark box testing device 200 is used to perform dark box testing on the radar 300. Both the airtightness testing device 90 and the dark box testing device 200 are existing technologies and will not be described in detail.

[0056] like Figure 2 and Figure 6As shown, in some embodiments, the aging device 80 includes an aging chamber 81, an off-line conveying mechanism 83, and a handling mechanism 84; the off-line conveying mechanism 83 includes a first conveyor belt 831, which is capable of conveying the radar 300; the handling mechanism 84 is capable of temporarily storing the radar 300 to be aged conveyed from the assembly line onto the first conveyor belt 831, or transferring the radar 300 to be aged conveyed from the assembly line and on the first conveyor belt 831 onto a fixing fixture 82 for fixation.

[0057] When a radar 300 that needs to be aged arrives at the assembly line, it can be transported to a fixed fixture 82 by a transport mechanism 84 for aging. If there is no available fixed fixture 82, the radar 300 to be aged can be temporarily placed on the first conveyor belt 831 by the transport mechanism 84, so that the production process can be stopped without interruption and the need to wait due to the lack of available fixed fixtures 82 can be avoided. When an available fixture becomes available, the transport mechanism 84 can transport the radar 300 to be aged temporarily stored on the first conveyor belt 831 to the fixed fixture 82 for aging, thereby improving production efficiency.

[0058] In addition, to avoid the radar 300 being stacked, the first conveyor belt 831 can also adjust the placement position of the radar 300 for the handling mechanism 84, reducing the frequency of adjustments to the handling mechanism 84.

[0059] like Figure 2 As shown, in some embodiments, the aging device 80 includes a first feeding mechanism 85, which receives radar 300 to be aged from the assembly line. The first feeding mechanism 85 may include a conveyor belt and a barcode scanner. The barcode scanner obtains information about the radar 300 for easy traceability. The conveyor belt can also transport the radar 300 to the loading position for easy handling by the handling mechanism 84. After the first feeding mechanism 85 completes information collection, the handling mechanism 84 can choose to transport the radar 300 to the fixed fixture 82 for aging, or transport it to the first conveyor belt 831 for temporary storage, depending on the availability of the fixed fixture 82.

[0060] In some embodiments, the aging chamber 81 includes several drawers 811, each drawer 811 containing multiple fixing fixtures 82. Each fixing fixture 82 includes a fixing base 821, on which a probe plug 822 is provided to cooperate with the radar 300, allowing the radar 300 to be inserted into the probe plug 822 from top to bottom for normal aging operation. The fixing base 821 also includes a fixing component 823, which can fix or loosen the radar 300 connected to the probe plug 822, thereby ensuring the stability of the connection during aging testing and allowing it to be released after aging for easy removal by the handling mechanism 84.

[0061] Specifically, such as Figures 3 to 5 As shown, the fixing assembly 823 includes a bearing 8231, which is spaced apart from the probe plug 822. A receiving groove 8232 is provided on the side of the bearing 8231 facing the probe plug 822. The opening of the receiving groove 8232 is horizontally facing the probe plug 822. The groove wall of the receiving groove 8232 is provided with a sliding groove extending towards or away from the probe plug 822. A stop member 8233 is provided within the receiving groove 8232, slidingly engaged within the sliding groove. A first elastic member 8234 is also provided between the stop member 8233 and the bearing 8231, which keeps the stop member 8233 inclined towards the probe plug 822. Therefore, when the radar 300 is plugged into the probe plug 822, the stop member 8233, under the action of the first elastic member 8234, abuts against the radar 300, securing it firmly on the probe plug 822. Exemplarily, the abutment member 8233 includes an abutment seat 82331, which slides on a groove. A first elastic member 8234 connects the abutment seat 82331 and the bearing seat 8231. The abutment seat 82331 can move closer to or further away from the probe plug 822. A bearing 82332 is rotatably connected to the abutment seat 82331, so that the movement of the abutment seat 82331 drives the bearing 82332 to move closer to or further away from the probe plug 822. The bearing 82332 facilitates the insertion and removal of the radar 300. Exemplarily, the first elastic member 8234 is a spring.

[0062] In some embodiments, the fixing assembly 823 further includes a retaining strip 8235 and a rotating pin 8236. The rotating pin 8236 is disposed between the first end and the second end of the retaining strip 8235. The retaining strip 8235 is rotatably connected to the fixing seat 821 through the rotating pin 8236. The retaining strip 8235 and the shaft seat 8231 are located on opposite sides of the probe plug 822. A second elastic element 8237 is connected between the first end of the retaining strip 8235 and the fixing seat 821. Since the side of the radar 300 has a limiting groove (this is the prior art), when the radar 300 contacts the probe plug 822, the radar 300 is pressed down to abut the second end of the retaining strip 8235. As the second end of the retaining strip 8235 is pressed down, the retaining strip 8235 will be embedded in the limiting groove. Thus, the second end of the retaining strip 8235 abuts against the groove wall of the limiting groove through the second elastic element 8237, further pressing the radar 300 and making the radar 300 and the probe plug 822 in close contact. Applying force to the first end of the locking strip 8235 allows it to approach the fixing seat 821. The first end compresses the second elastic element 8237 to accumulate potential energy. At the same time, the second end of the locking strip 8235 moves away from the fixing seat 821, allowing the second end of the locking strip 8235 to detach from the groove wall of the limiting groove. This allows the radar 300 to be easily pulled out and quickly detached from the probe plug 822. Subsequently, the locking strip 8235 can return to its original position through the second elastic element 8237.

[0063] like Figure 2 and Figure 8 As shown, the corresponding transport mechanism 84 includes a transport drive 841 and a transport manipulator 842 disposed at the output end of the transport drive 841. The transport drive 841 drives the transport manipulator 842 to move between various mechanisms. The transport manipulator 842 can grip and transport the radar 300. The transport drive 841 and the transport manipulator 842 are existing technologies and will not be described in detail. The transport manipulator 842 is also provided with a latching member 843 that can abut against the first end of the retaining strip 8235. When it is necessary to detach the radar 300 from the probe plug 822, the latching member 843 abuts against the first end of the retaining strip 8235, and the transport manipulator 842 grasps the radar 300 and moves it away from the probe plug 822. Specifically, the fastener 843 includes a telescopic drive 8431 mounted on the handling robot 842. The output end of the telescopic drive 8431 is connected to a stop shaft 8432. Thus, the telescopic drive 8431 can selectively drive the stop shaft 8432 to stop the locking bar 8235 only when the radar 300 is disengaged.

[0064] When the transport mechanism 84 places excess radars 300 to be aged onto the first conveyor belt 831, the radars 300 are generally placed horizontally for stability. However, when the radars 300 need aging, they need to be vertically connected to the probe plugs 822. This facilitates reversal and reduces the complexity of the transport mechanism 84. Figure 6 As shown, in some embodiments, the off-line conveying mechanism 83 further includes a rotating component 832. The rotating component 832 is disposed at one end of the first conveyor belt 831 near the handling mechanism 84. When the radar 300 needs to be transferred, the first conveyor belt 831 conveys the radar 300 to the rotating component 832. The flipping assembly clamps the radar 300 on the first conveyor belt 831 and flips it over. Then, the handling mechanism 84 directly moves it to the fixing fixture 82 for fixation.

[0065] Specifically, such as Figure 7As shown, the rotating assembly 832 includes a rotating support plate 8321. Two rotating support plates 8321 are arranged opposite each other on both sides of the first conveyor belt 831. The rotating support plate 8321 is provided with a rotating shaft 8322, which spans across the first conveyor belt 831. The rotating support plate 8321 also has a rotating drive component 8325. The rotating shaft 8322 is connected to the output end of the rotating drive component 8325, thereby driving it to rotate. The rotating shaft 8322 is provided with a clamping drive component 8323. The output end of the clamping drive component 8323 is connected to a gripper 8324 capable of clamping the radar 300. After the radar 300, which is horizontally placed on the first conveyor belt 831, is clamped by the gripper 8324, the rotation of the gripper 8324 is driven to make it vertical, waiting for the transport mechanism 84 to transport it. After transport, it is vertically inserted into the probe plug 822. For example, the rotary drive 8325 is a rotary cylinder or a rotary motor, the clamping drive 8323 is a clamping cylinder, and the structure of the gripper 8324 is not specifically limited and can be selected according to different radars 300.

[0066] In some embodiments, the rotating component 832 is disposed at one end of the first conveyor belt 831 near the handling mechanism 84, thereby facilitating the handling mechanism 84 to pick up and remove the components.

[0067] like Figure 6 As shown, a positioning monitoring element 833 is further provided on the first conveyor belt 831. The positioning monitoring element 833 is signal-connected to the rotating assembly 832, thereby monitoring the position of the radar 300 on the first conveyor belt 831 and providing a basis for starting the rotating assembly 832. Exemplarily, the positioning monitoring element 833 may be, but is not limited to, an infrared monitoring element.

[0068] like Figure 2 As shown, in some embodiments, the aging device 80 also includes an NG conveying mechanism 87 and a unloading mechanism 88. The conveying mechanism 84 can move the unqualified radars 300 after aging from the fixed fixture 82 to the NG conveying mechanism 87; and move the qualified ones to the unloading mechanism 88 for unloading. The NG conveying mechanism 87 and the unloading mechanism 88 are both existing technologies and will not be described in detail.

[0069] like Figure 2As shown, in some embodiments, the aging device 80 further includes a pre-programming mechanism 89. The pre-programming mechanism 89 provides additional programming functionality for the radar 300 that needs to be programmed. In the current embodiment, the radar 300 that has been repaired after NG (outdated) can be placed in the pre-programming mechanism 89 for programming, and then transported by the transport mechanism 84 to the fixing fixture 82. If there is no spare fixing fixture 82, it can be temporarily stored on the first conveyor belt 831 by the transport mechanism 84, awaiting aging test. The pre-programming mechanism 89 is prior art and will not be described in detail.

[0070] In some embodiments, the aging device 80 further includes a second feeding mechanism 86, which includes a second conveyor belt and a pre-fixing fixture 82. The pre-fixing fixture 82 is fixed to the second conveyor belt. A transport mechanism 84 can transport the radar 300 fixed to the pre-fixing fixture 82 to the fixing fixture 82 inside the aging chamber 81. The first feeding mechanism 85 corresponds to automatic feeding on the assembly line. The second feeding mechanism 86 corresponds to manual feeding, where an operator inserts the radar 300 into the pre-fixing fixture 82, which is then transported by the transport mechanism 84, increasing the feeding pathways. In the current embodiment, the pre-fixing fixture 82 and the fixing fixture 82 have the same structure.

[0071] like Figures 9 to 14 As shown, the laser marking device 100 includes a flipping mechanism 101, a marking mechanism 102, a moving mechanism 103, and a pick-and-place mechanism 104. The flipping mechanism 101 includes a lifting drive 1011, a flipping drive 1012 at the output end of the lifting drive 1011, and a vacuum adsorption disk 1013 at the output end of the flipping drive 1012. The vacuum adsorption disk 1013 is used to adsorb and fix the radar 300. The flipping drive 1012 can drive the vacuum adsorption disk 1013 to flip, and the lifting drive 1011 can drive... The vacuum adsorption plate 1013 is raised and lowered; the marking mechanism 102 is configured to mark the radar 300; the moving mechanism 103 includes a moving drive 1031 and a platform 1032, the platform 1032 is used to support and fix the radar 300, and the moving drive 1031 can drive the platform 1032 to move between the vacuum adsorption plate 1013 and the marking mechanism 102; the pick-and-place mechanism 104 is used to place the radar 300 transmitted from the airtightness testing device 90 onto the vacuum adsorption plate 1013 or to remove the radar 300 from the platform 1032.

[0072] When marking is required on the radar 300, the radar 300, which is conveyed from the upstream airtightness testing device 90, is first placed on the vacuum adsorption plate 1013 by the pick-and-place mechanism 104 for adsorption and fixation. Then, the vacuum adsorption plate 1013 is flipped by the flipping drive component 1012. Subsequently, the lifting component drives the vacuum adsorption plate 1013 to descend, placing the radar 300 on the platform 1032 for fixation. The moving drive component 1031 drives the platform 1032 to move to the marking mechanism 102 to mark the radar 300. Marking is performed; before marking is completed, there is no need for the pick-and-place mechanism 104 to transfer the radar 300 a second time, avoiding secondary positioning and placement errors. After the vacuum adsorption plate 1013 places the radar 300 on the stage 1032, and before the pick-and-place mechanism 104 needs to remove the marked radar 300, the pick-and-place mechanism 104 can place the next radar 300 to be marked on the vacuum adsorption plate 1013 for adsorption, avoiding long waiting time for the pick-and-place mechanism 104 and improving production efficiency.

[0073] like Figures 10 to 13 As shown, in some embodiments, the moving drive 1031 is a linear slide, which is existing technology and will not be described in detail. In some alternative embodiments, the moving drive 1031 may also be a cylinder or the like. The stage 1032 is fixed to the output end of the linear slide. To facilitate positioning, the stage 1032 is provided with a fixing part 10321, which restricts the radar 300 and prevents the radar 300 from shaking during transfer or marking. Exemplarily, the fixing part 10321 is a contoured groove formed on the stage 1032 and matching the radar 300, so that the radar 300 can be partially embedded into the contoured groove for restriction. In other embodiments, the fixing part 10321 may also be a clamping claw or other components for fixing.

[0074] In the current embodiment, the flipping mechanism 101 and the marking mechanism 102 are arranged on one side of the linear slide, making the overall layout of the device more compact. In some embodiments, the adsorption surface of the vacuum adsorption plate 1013 is provided with a plurality of positioning elements 10134, thereby positioning the radar 300 placed on the vacuum adsorption plate 1013 through the positioning elements 10134. After the vacuum adsorption plate 1013 is flipped, the radar 300 can be directly placed in the contour groove, avoiding the need for repositioning during placement. For the mounting holes on the radar 300 housing, the positioning elements 10134 in the current embodiment are positioning pins. When placing the radar 300, the positioning pins are simply inserted into the mounting holes. It is understood that the form of the positioning elements 10134 may also be different for different marking radars 300.

[0075] like Figure 11As shown, since vacuum adsorption requires connection to an external air extraction device via an external air pipe, in order to avoid interference of the external air pipe with the placement of the radar 300, the vacuum adsorption disk 1013 includes an adsorption disk body 10131. The adsorption disk body 10131 is provided with an adsorption hole 10135. The surface where the adsorption hole 10135 is located is the adsorption surface mentioned above. Of course, the adsorption disk body 10131 is also provided with an adsorption channel that connects to the adsorption hole 10135, which will not be described in detail here. The adsorption disk 10131 is also provided with a groove 10133. The groove 10133 is not on the same plane as the adsorption hole 10135. The adjacent surfaces of the adsorption disk 10131 and the adsorption hole 10135 are provided with the groove 10133. The external connector 10132 is provided in the groove 10133 to connect the adsorption channel. The external air pipe is connected to the external connector 10132 and the external air extraction device to realize vacuum adsorption. The external air pipe is also located on the side of the vacuum adsorption disk 1013 to avoid interference problems.

[0076] Furthermore, to avoid interference with the rotation of the external air pipe during the rotation of the vacuum adsorption disk 1013, the lifting drive 1011 in this embodiment is a lifting cylinder, with a fixed plate 1014 at its output end. The flipping drive 1012 is a rotary cylinder, fixed to the fixed plate 1014. The fixed plate 1014 has a first notch 10141 corresponding to the position of the rotary cylinder's through hole (rotary cylinders generally have through holes, which is prior art and will not be described in detail). A rotating plate 1015 is installed at the output end of the cylinder. A second notch is provided on the rotating plate 1015 corresponding to the position of the through hole of the rotary cylinder. The second notch corresponds to the embedding position of the external connector 10132. That is, the first notch 10141, the second notch, the through hole of the rotary cylinder, and the groove 10133 are collinear, allowing the external air pipe to sequentially pass through the second notch, the through hole of the rotary cylinder, and the first notch 10141 to connect to the outside. This facilitates the external air pipe's rotation with the adsorption disc 10131, avoiding interference. For example, the external air pipe can be a flexible hose.

[0077] In some embodiments, the flipping mechanism 101 further includes a position detection element 1016, which is disposed at the output end of the lifting drive element 1011 so as to rise and fall together with the vacuum adsorption disk 1013. The position detection element 1016 detects the position of the adsorption surface of the vacuum adsorption disk 1013, accurately determining whether the radar 300 on the vacuum adsorption disk 1013 is placed on the stage 1032, thereby controlling the vacuum adsorption disk 1013. Exemplarily, the position detection element 1016 is an infrared sensor. Two mounting plates are disposed on the fixing plate 1014, located on both sides of the vacuum adsorption disk 1013. One mounting plate has an infrared sensor transmitter, and the other mounting plate has an infrared sensor receiver.

[0078] like Figure 10 As shown, in some embodiments, the marking mechanism 102 includes a laser generator 1021 and a welding fume purifier 1022. The smoke extraction port of the welding fume purifier 1022 is located below the laser outlet of the laser generator 1021 and can absorb the welding fumes generated during marking. Both the laser generator 1021 and the welding fume purifier 1022 are existing technologies and will not be described in detail.

[0079] In some embodiments, the laser marking apparatus 100 further includes a quality inspection mechanism 105. After marking is completed, the stage 1032 moves to the quality inspection mechanism 105, which can at least inspect the marking quality of the radar 300 on the stage 1032. Exemplarily, the quality inspection mechanism 105 includes two CCD cameras, one located above the linear slide and the other located to the side of the linear slide. When the stage 1032 moves to the position of the CCD camera above the linear slide, the CCD camera inspects the marking effect; and when the stage 1032 moves to the position of the CCD camera located to the side of the linear slide, the CCD camera inspects the pins at the head of the radar 300.

[0080] like Figure 14 As shown, in some embodiments, the pick-and-place mechanism 104 includes a pick-and-place drive 1041 and a suction cup clamp 1042. The suction cup clamp 1042 is disposed at the output end of the pick-and-place drive 1041. The pick-and-place drive 1041 drives the suction cup clamp 1042 to move, thereby placing the radar 300 onto the vacuum suction plate 1013 or removing the radar 300 from the stage 1032. For example, the pick-and-place drive 1041 is a robotic arm, and the robotic arm is equipped with multiple sets of suction cup clamps 1042, thereby enabling the pick-and-place of multiple radars 300 and reducing the movement frequency of the robotic arm.

[0081] The aforementioned automated intelligent production system for radar can seamlessly complete the assembly and testing of radar 300, thereby improving the production efficiency of radar 300.
