Description

Technical Field

[0001] The present invention belongs to the technical field of automotive parts processing, and particularly relates to an assembly and pressing device for an external rearview mirror lens. Background Art

[0002] Automotive rearview mirrors are located on the left and right sides of the front of the vehicle, as well as in front of the interior of the vehicle. The automotive rearview mirror reflects the conditions behind, to the sides, and below the vehicle, enabling the driver to indirectly see clearly the conditions in these positions. It plays the role of a "second pair of eyes", expanding the driver's field of vision.

[0003] Mostly, the frame and the lens are assembled together by a snap connection method. During assembly, the lens is pressed into the interior of the frame, and the snap structure in the frame holds the lens, thus completing the assembly work between the lens and the frame.

[0004] However, during the use of existing assembly pressing devices, the following problems exist:

[0005] Firstly, it cannot detect whether the connection between the lens body and the frame body is stable. If the lens body is not fully pressed into the interior of the frame body, the lens body is likely to detach from the frame body, which may easily cause the lens body to fall in the processing workshop, posing a safety hazard to the subsequent processing process.

[0006] Secondly, the assembled rearview mirror after pressing needs to be manually unloaded, increasing the workload of the workers. To solve the above problems, the present application proposes an assembly and pressing device for an external rearview mirror lens. Summary of the Invention

[0007] The purpose of the present invention is to provide an assembly and pressing device for an external rearview mirror lens to solve the problems raised in the above background art.

[0008] To achieve the above purpose, the present invention provides the following technical solution. An assembly and pressing device for an external rearview mirror lens includes an assembly table and an assembly frame. A lifting unit is installed on the assembly frame. The lifting unit is connected to a pressing support, and the pressing support is connected to a pressing block.

[0009] A cylinder is provided on the assembly frame, and the cylinder is connected to a frame pressing plate.

[0010] A pressing detection unit is provided on the pressing support. The pressing detection unit includes a tensile force detection unit, a suction cup, and a power pump. The pressing detection unit has an adsorption detection state. When the pressing detection unit is in the adsorption detection state, the suction cup sucks the lens body by suction, and the frame pressing plate presses on the frame body.

[0011] A blanking unit is provided outside the assembly frame. The blanking unit includes a guiding cloth, a position adjusting unit, and a storage box.

[0012] Preferably, the lifting unit is connected with a lifting plate, and the pressing bracket is installed on the lifting plate.

[0013] Preferably, the air cylinder is installed on the lifting plate, and the outer wall of the frame pressing plate is attached to the outer wall of the assembly rack.

[0014] Preferably, the pressing detection unit further includes a support plate and a detection plate. The tensile force detection unit is arranged on the support plate and is used for measuring the force received by the detection plate.

[0015] Preferably, a plurality of adjusting shafts are arranged at the detection plate and are circumferentially and arrayed around the center line of the pressing block. The adjusting shafts are inserted with mounting seats, and the mounting seats are detachably installed on the detection plate.

[0016] Preferably, the adjusting shaft is connected with a driving unit, and the driving unit is used for driving the adjusting shaft to rotate forward and backward.

[0017] Preferably, the driving unit includes a first gear, a second gear and a driving motor. The first gear is sleeved outside the adjusting shaft. The first gear is connected with the second gear through meshing transmission of teeth, and the second gear is connected with the output shaft of the driving motor through a key.

[0018] Preferably, the adjusting shaft is connected with a square sleeve through threads. A bottom plate is arranged at the bottom of the square sleeve. The suction cup and the power pump are both arranged on the bottom plate. A guide sleeve is arranged on the detection plate. The square sleeve is inserted into the guide sleeve, and the square sleeve and the guide sleeve can only slide relatively up and down.

[0019] Preferably, the blanking unit further includes two inclined plates. The guiding cloth is located between the two inclined plates. The inclined plates are connected with a moving frame. A slider, a lead screw, a track and a power motor are arranged on the lower side of the moving frame, and the slider is connected with the moving frame.

[0020] Preferably, the slider is slidably connected with the track. The slider is connected with the lead screw through threads. The power motor is used for driving the lead screw to rotate. A baffle is arranged on one side of the storage box far away from the assembly table, and the baffle is used for preventing the frame body from not sliding into the interior of the storage box.

[0021] Compared with the prior art, the beneficial effects of the present invention are:

[0022] 1. When the pressing and detecting unit of the present invention is in the adsorption detection state, the lifting unit and the cylinder are started at this time. The lifting unit drives the lifting plate to move upward, and then drives the pressing bracket and the suction cup to move upward. The cylinder drives the frame pressing plate to move downward, so that the frame pressing plate always presses on the frame body. In this way, there is a tendency of relative movement between the lens body sucked by the suction cup and the frame body. The tensile force borne by the lens body is measured by the tensile force detection unit. If the tensile force is normal, the connection between the lens body and the frame body is tight. If the tensile force is too small, it means that the connection between the lens body and the frame body is not tight, which can detect the connection between the lens body and the frame body, re-press the lens body with unsuccessful pressing, and avoid the separation of the lens body and the frame body after pressing.

[0023] 2. When the blanking unit of the present invention is in the blanking state, the guiding cloth moves to the lower side of the suction cup under the drive of the position adjusting unit. At this time, the suction cup is in the starting state and sucks the lens body. At this time, the lens body and the frame body have been adsorbed to the area above the guiding cloth. When the suction cup releases the lens body, the frame body and the lens body fall onto the guiding cloth under the action of gravity and slide into the storage box along the inclined guiding cloth, eliminating the need for manual blanking and reducing the workload of workers.

[0033] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0034] Refer to Figures 1-6 , an external rearview mirror lens assembly and pressing device, including an assembly table 3 and an assembly frame 4. A storage groove 301 for storing the frame body 1 is arranged in the assembly table 3.

[0035] It should be noted that a lifting unit 5 is installed on the assembly frame 4. The lifting unit 5 is connected with a pressing bracket 7. The lifting unit 5 is used to drive the pressing bracket 7 to move up and down. A pressing block 8 is arranged at the bottom of the pressing bracket 7. The pressing block 8 is used to press the lens body 2 into the frame body 1. A corresponding buckle structure is arranged in the frame body 1. By pressing the lens body 2 downward, the lens body 2 can be pressed into the frame body 1, thereby completing the assembly work between the lens body 2 and the frame body 1.

[0036] Specifically, the lifting unit 5 is connected with a lifting plate 6, and the pressing bracket 7 is installed on the lifting plate 6.

[0037] In order to ensure that the position of the frame body 1 does not shake during the process of the pressing block 8 pressing the lens body 2, a cylinder 9 is arranged outside the assembly frame 4. The output end of the cylinder 9 is connected with a frame pressing plate 10. Specifically, the cylinder 9 is installed on the lifting plate 6, and the outer wall of the frame pressing plate 10 is attached to the outer wall of the assembly frame 4. The two can slide up and down relatively. During the process of the pressing block 8 pressing the lens body 2, the frame pressing plate 10 presses on the frame body 1 to fix the position of the frame body 1 by pressure and avoid its displacement.

[0038] After the pressing block 8 presses the lens body 2 into the frame body 1, it is necessary to detect whether the connection between the lens body 2 and the frame body 1 is stable. If the lens body 2 is not fully pressed into the frame body 1, the lens body 2 is likely to detach from the frame body 1, which may easily cause the lens body 2 to fall in the processing workshop, posing a safety hazard to the subsequent processing process. In order to detect the stability of the connection between the lens body 2 and the frame body 1, a pressing detection unit 11 is provided on the pressing support 7. The pressing detection unit 11 includes a tensile force detection unit, a suction cup 1109, and a power pump 1110. The pressing detection unit 11 has an adsorption detection state and a separation state. When the pressing detection unit 11 is in the adsorption detection state, the suction cup 1109 sucks the lens body 2 by suction, and the frame pressing plate 10 presses on the frame body 1;

[0039] When the pressing detection unit 11 is in the adsorption detection state, at this time, the lifting unit 5 and the cylinder 9 are started. The lifting unit 5 drives the lifting plate 6 to move upward, and then drives the pressing support 7 and the suction cup 1109 to move upward, while the cylinder 9 drives the frame pressing plate 10 to move downward, so that the frame pressing plate 10 always presses on the frame body 1. In this way, there is a tendency of relative movement between the lens body 2 sucked by the suction cup 1109 and the frame body 1. The tensile force borne by the lens body 2 is measured by the tensile force detection unit. If the tensile force is normal, the connection between the lens body 2 and the frame body 1 is tight. If the tensile force is too small, it means that the connection between the lens body 2 and the frame body 1 is not tight, and the lens body 2 is not fully assembled onto the frame body 1, and it needs to be reassembled (it is necessary to confirm that the lens body 2 is not damaged due to the previous pressing before assembly).

[0040] It should be added that when the pressing detection unit 11 is in the separation state, there is a gap between the suction cup 1109 and the lens body 2.

[0041] Specifically, the pressing detection unit 11 further includes a support plate 1101 and a detection plate 1102. The tensile force detection unit is arranged on the support plate 1101, and the tensile force detection unit is used to measure the force received by the detection plate 1102;

[0042] More specifically, a plurality of adjustment shafts 1103 are arranged at the detection plate 1102 and are circumferentially arrayed around the center line of the pressing block 8. The adjustment shafts 1103 are inserted with mounting seats 1104, and the mounting seats 1104 are detachably mounted on the detection plate 1102. The adjustment shafts 1103 are connected with a driving unit 1105, and the driving unit 1105 is used to drive the adjustment shafts 1103 to rotate forward and backward;

[0043] It should be noted that with reference to Figure 5, the driving unit 1105 includes a first gear, a second gear, and a driving motor. The first gear is sleeved outside the adjusting shaft 1103. The first gear is connected to the second gear through gear meshing transmission. The second gear is key-connected to the output shaft of the driving motor. In this way, when the driving motor rotates forward and backward, the second gear can rotate together, and the second gear drives the first gear to rotate through gear meshing. During the forward and backward rotation of the adjusting shaft 1103, it can drive the square sleeve 1106 threadedly connected thereto to move up and down. The suction cup 1109 is arranged on the square sleeve 1106. In this way, the height of the suction cup 1109 can be adjusted to enable the pressing detection unit 11 to switch between the adsorption detection state and the separation state.

[0044] It should be added that the adjusting shaft 1103 is threadedly connected with a square sleeve 1106. A bottom plate 1107 is arranged at the bottom of the square sleeve 1106. Both the suction cup 1109 and the power pump 1110 are arranged on the bottom plate 1107. A guide sleeve 1108 is arranged on the detection plate 1102. The square sleeve 1106 is inserted into the guide sleeve 1108, and the square sleeve 1106 and the guide sleeve 1108 can only slide relatively up and down.

[0045] The assembled spectacle frame body 1 and lens body 2 need to be removed from the assembly table 3. To facilitate the removal of the above two, a blanking unit 12 is arranged outside the assembly rack 4. The blanking unit 12 includes a guide cloth 1202, a position adjusting unit, and a storage box 1207. The position adjusting unit is used to adjust the position of the guide cloth 1202. The blanking unit 12 has a blanking state and a retracted state. When the blanking unit 12 is in the blanking state, the guide cloth 1202 is inclined and arranged under the spectacle frame body 1 sucked by the suction cup 1109, and the guide cloth 1202 faces the storage box 1207. In this way, after the suction cup 1109 releases the lens body 2, the spectacle frame body 1 and the lens body 2 fall onto the guide cloth 1202 under the action of gravity and slide into the storage box 1207 along the inclined guide cloth 1202.

[0046] Specifically, the blanking unit 12 further includes two inclined plates 1201. The guide cloth 1202 is located between the two inclined plates 1201. The inclined plates 1201 are connected with a moving frame 1203. The lower side of the moving frame 1203 is provided with a slider 1204, a lead screw 1205, a track 1206, and a power motor. The slider 1204 is connected to the moving frame 1203. The slider 1204 is slidably connected to the track 1206. The slider 1204 is threadedly connected to the lead screw 1205. The power motor is used to drive the lead screw 1205 to rotate. It should be noted that a baffle 1208 is arranged on the side of the storage box 1207 away from the assembly table 3. The baffle 1208 is used to prevent the spectacle frame body 1 from not sliding into the storage box 1207.

[0047] Working principle:

[0048] A pressing block 8 is provided at the bottom of the pressing bracket 7. Driven by the lifting unit 5, the pressing block 8 can move downward, and the lens body 2 can be pressed into the frame body 1. A corresponding buckle structure is provided in the frame body 1. By pressing the lens body 2 to move downward, the lens body 2 can be pressed into the frame body 1, thus completing the assembly work between the lens body 2 and the frame body 1.

[0049] When the pressing detection unit 11 is in the adsorption detection state, the lifting unit 5 and the cylinder 9 are started at this time. The lifting unit 5 drives the lifting plate 6 to move upward, and then drives the pressing bracket 7 and the suction cup 1109 to move upward, while the cylinder 9 drives the frame pressing plate 10 to move downward, so that the frame pressing plate 10 always presses on the frame body 1. In this way, a relative movement trend is generated between the lens body 2 sucked by the suction cup 1109 and the frame body 1. The tension borne by the lens body 2 is measured by the tension detection unit. If the tension is normal, the connection between the lens body 2 and the frame body 1 is tight. If the tension is too small, it means that the connection between the lens body 2 and the frame body 1 is not tight, and the connection between the lens body 2 and the frame body 1 can be detected.

[0050] When the blanking unit 12 is in the blanking state, the guiding cloth 1202 moves to the lower side of the suction cup 1109 driven by the position adjusting unit. At this time, the suction cup 1109 is in the starting state, and it sucks the lens body 2. At this time, the lens body 2 and the frame body 1 have been adsorbed to the area above the guiding cloth 1202. When the suction cup 1109 releases the lens body 2, the frame body 1 and the lens body 2 fall onto the guiding cloth 1202 under the action of gravity and slide into the storage box 1207 along the inclined guiding cloth 1202.

[0051] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
