Description

Technical Field

[0001] The present invention belongs to the technical field of automobile parts production equipment, and in particular relates to automatic assembly equipment and method for new energy automobile connectors. Background Art

[0002] The automatic assembly equipment for new energy vehicle connectors is a highly automated mechanical equipment that is specifically used to assemble the various basic structural components of new energy vehicle connectors (such as housings, terminals, seals, locking parts, etc.) into finished products through precise mechanical movements and control systems. This equipment plays a vital role in the manufacturing process of new energy vehicles because it can greatly improve production efficiency and product quality while reducing labor costs and human errors.

[0003] In the prior art, a connector that meets the quality requirements is fixed on an assembly tool, and a suitable glue is selected according to the requirements of the connector, and the glue is applied to the required position of the connector by a glue sprayer or other automatic coating device.

[0004] There are still some problems in the actual application of the above scheme. Although the existing automatic glue coating device can complete the coating of the required parts of the connector, the glue has poor fluidity and the part of the connector that needs to be coated is not flat, so the glue cannot be fully applied to the area that needs to be coated, which will cause the connection point to loosen and the seal to be poor, thereby affecting the overall performance and reliability of the connector. At the same time, it will also cause the connector to be more susceptible to environmental influences (such as temperature changes, humidity, chemicals, etc.) after long-term use, thereby affecting its long-term stability and service life. Secondly, during the use of the added uniform coating mechanism, the machine vibration will cause the glue to fall or flow out from the part of the connector that needs to be coated, thereby forming an unnecessary heat insulation layer on the outside of the connector, affecting the heat conduction performance, and causing local overheating. At the same time, the falling or flowing of glue will leave marks or residues on the surface of the connector, affecting the appearance quality of the product.

[0016] A method for automatically assembling a connector for a new energy vehicle, specifically comprising:

[0017] Raw material loading: Place the connectors that meet the quality requirements into the working frame;

[0018] Glue coating: When the connector is placed inside the working frame, the coating nozzle moves back and forth to coat the connector. The wave structure on the side of the reciprocating vibration plate close to the working frame vibrates with the wave plate when the reciprocating vibration plate moves, so that the glue coating can be more even.

[0019] Parts assembly: Install the parts onto the connector one by one according to the predetermined assembly sequence. Then, use the corresponding automated equipment to process the parts that need to be crimped, welded or fastened.

[0020] Quality inspection: First, the assembled connector is visually inspected through a visual inspection system or manual inspection. Second, the electrical performance and sealing performance of the connector are tested using professional testing equipment to ensure that it meets relevant standards and requirements.

[0021] The glue coating is specifically as follows: first, a connector that meets the quality requirements is placed inside the working frame. At this time, the coating nozzle will move along the guide on the top of the workbench, and the connector can be coated while moving. When the coating work is completed on one side of the connector, the driving source will start. When the driving source is started, the second rotating shaft fixedly connected to its output shaft will rotate, thereby driving the first connecting rod and the moving column to rotate. Since the moving column slides in the groove opened in the middle of the arc-shaped swing arm, the arc-shaped swing arm will swing, thereby driving the arc-shaped gear on the top of the arc-shaped swing arm to rotate in a small range. At this time, the reciprocating vibration plate meshed with the arc-shaped gear on the top of the arc-shaped swing arm will perform a straight reciprocating movement along the guide openings set on both sides of the limiting rectangular frame. At this time, the wave-shaped structure in the reciprocating vibration plate will cooperate with the wave plate to vibrate, thereby enabling the glue coated on the coating part of the connector to flow to every corner of the coating part of the connector.

[0022] The beneficial effects of the present invention are as follows:

[0023] 1. The present invention starts the driving source, and the second rotating shaft fixedly connected to the output shaft of the driving source will drive the first connecting rod and the moving column to rotate synchronously. Since the moving column slides in the guide groove opened inside the arc-shaped swing arm connecting rod, the arc-shaped swing arm will rotate around the first fixed axis when the first connecting rod drives the moving column to rotate, and can further drive the arc-shaped gear on the top of the arc-shaped swing arm to swing slightly. At this time, the reciprocating vibration plate meshing with the arc-shaped swing arm will perform reciprocating linear motion. Since the reciprocating vibration plate is provided with a slope structure matched with the wave plate on the side close to the working frame, the reciprocating vibration plate will generate vibration while reciprocating, so that the glue can be evenly coated on the coating area required by the connector to improve the sealing of the connector, thereby ensuring the overall performance and reliability of the connector and extending the service life of the connector.

[0024] 2. The present invention enables the sliding block in the guide groove opened on the outer ring surface of the third rotating shaft to slide through the rotation of the third rotating shaft. Since the sliding block is fixedly connected to the reciprocating cylinder through the second connecting rod, the sliding block will drive the reciprocating cylinder to move upward along the guide of the limit ring when sliding inside the guide groove. At this time, the connecting block fixed on the top of the reciprocating cylinder will also move synchronously. When the reciprocating cylinder moves to a certain height with the connecting block, the limit plate will rotate around the second fixed shaft due to the obstruction of the fixed rod. At this time, the limit plate that has been rotated to a vertical degree will block the glue coated on the connector to prevent the glue from falling off due to the swinging vibration mechanism during operation, thereby avoiding the formation of a heat insulation layer on the outside of the connector due to the coverage of the glue. At the same time, preventing the glue from falling off can improve the appearance quality of the product.

[0025] 3. The present invention pushes the second L-shaped push rod and the reciprocating sliding rod fixed on the end face of the second L-shaped push rod to move in a direction away from the supporting base through the reciprocating motion of the first L-shaped push rod. When the reciprocating sliding rod moves, it will drive the moving piston fixedly connected to its end face to move along the side wall of the inner cavity of the piston cylinder. At this time, the reciprocating spring will be compressed, and the inside of the piston cylinder will be filled with air. When the first L-shaped push rod moves in the opposite direction, the reciprocating spring will reset and the air inside the piston cylinder will be sprayed out through the nozzle by the moving piston, thereby achieving preliminary drying of the glue, and then promoting the glue to reach the initial solidification state faster, which helps to shorten the entire production cycle and improve production efficiency.

[0040] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0041] Embodiment 1

[0042] like Figures 1 to 9 As shown, one embodiment of the present invention is:

[0043] An automatic assembly device for a new energy vehicle connector includes an assembly adhesion device 1, wherein the assembly adhesion device 1 includes a workbench 101, a side wall of the workbench 101 is provided with an inner cavity, a support base 102 is fixedly connected to the upper surface of the workbench 101, a first rotating shaft 103 is rotatably connected to the middle of the support base 102, one end of the first rotating shaft 103 is fixedly connected to a work frame 104, a coating nozzle 105 is slidably connected to the top of the workbench 101, and a swing vibration mechanism 2 is arranged on the upper surface of the workbench 101;

[0044] The oscillating vibration mechanism 2 is used for uniform coating of glue.

[0045] Specifically, although the existing automatic glue coating device can complete the coating of the required parts of the connector, due to the poor fluidity of the glue and the unevenness of the parts of the connector to be coated, the glue cannot be fully applied to the areas to be coated, which will cause the connection points to become loose and the seal to be loose, thereby affecting the overall performance and reliability of the connector. At the same time, it will also make the connector more susceptible to environmental influences (such as temperature changes, humidity, chemicals, etc.) after long-term use, thereby affecting its long-term stability and service life;

[0046] Therefore, the present invention solves this problem by setting up a certain structure, and places the connector that meets the quality requirements with the side to be coated facing upward in the working frame 104. At this time, the side of the connector that needs to be coated can be coated by the coating nozzle 105. Since the coating nozzle 105 has no way to coat the tiny corners of the connector during the coating process, the reciprocating motion of the mechanism in the swing vibration mechanism 2 will cause the working frame 104 to vibrate, so that the glue can be evenly coated on the coating area required by the connector to improve the sealing of the connector, thereby ensuring the overall performance and reliability of the connector and extending the service life of the connector.

[0047] like Figure 2 As shown, the swing vibration mechanism 2 of this embodiment includes a support frame 201, the support frame 201 is fixedly connected to the upper surface of the workbench 101, the side wall of the working frame 104 is fixedly connected to the wave plate 214, and the top of the support frame 201 is fixedly connected to the limited position rectangular frame 203.

[0048] Specifically, the limiting rectangular frame 203 fixed on the top of the support frame 201 is used to limit and guide the subsequent device, and the wave plate 214 fixed on the side wall of the working frame 104 will cooperate with the subsequent device to complete the vibration of the working frame 104.

[0049] like Figure 3 As shown, in this embodiment, a driving source 202 is provided on the side wall of the support frame 201, and the output shaft of the driving source 202 is fixedly connected to the second rotating shaft 204, and the second rotating shaft 204 runs through the middle part of the support frame 201, and the end of the second rotating shaft 204 away from the driving source 202 is fixedly connected to the first connecting rod 205, and the end of the first connecting rod 205 away from the second rotating shaft 204 is fixedly connected to the moving column 206, and the end of the moving column 206 away from the first connecting rod 205 is provided with an arc-shaped swinging rod 207, and a guide groove is opened in the middle of the arc-shaped swinging rod 207, and the moving column 206 is slidably connected inside the sliding groove of the arc-shaped swinging rod 207.

[0050] Specifically, when the coating nozzle 105 completes coating, the driving source 202 will be started. When the driving source 202 is turned on, the second rotating shaft 204 fixed on the output shaft of the driving source 202 will rotate synchronously. When the second rotating shaft 204 rotates, it will drive the first connecting rod 205 away from the end of the driving source 202 to rotate, and at the same time, it will drive the moving column 206 fixed at the bottom of the first connecting rod 205 to rotate, and the moving column 206 is slid in the guide groove opened in the middle of the arc-shaped swing rod 207, and the guide groove opened in the middle of the arc-shaped swing rod 207 can cooperate with the subsequent device to convert the rotation of the arc-shaped swing rod 207 into swinging.

[0051] like Figure 2 , Figure 3 and Figure 4 As shown, the arc-shaped swing arm 207 of this embodiment is composed of an arc-shaped gear and a connecting rod. A first fixed shaft 208 is arranged in the middle of the arc-shaped swing arm 207. The first fixed shaft 208 is rotatably connected to the middle of the arc-shaped swing arm 207 and is fixedly connected to the support frame 201. The arc-shaped gear at the top of the arc-shaped swing arm 207 is meshed with a reciprocating vibration plate 209, and the reciprocating vibration plate 209 is against the wave plate 214.

[0052] Specifically, when the motion column 206 rotates, since the middle part of the arc-shaped swing arm 207 has a first fixed axis 208 fixed to the side of the driving source 202 and the arc-shaped swing arm 207 is in a rotational relationship with the first fixed axis 208, when the motion column 206 rotates around the second rotation axis 204, the arc-shaped swing arm 207 will swing. At the same time, since the arc-shaped swing arm 207 is composed of an arc-shaped gear and a connecting rod, when the arc-shaped swing arm 207 swings, the arc-shaped gear on its upper part will drive the reciprocating vibration plate 209 meshing with it to move linearly along the guide opening on the side of the limiting rectangular frame 203. At the same time, since the side of the reciprocating vibration plate 209 is adapted to the wavy structure of the wave plate 214, the reciprocating vibration plate 209 will vibrate the working frame 104 when it reciprocates, so that the glue can be evenly coated on the coating area required by the connector to improve the sealing of the connector, thereby ensuring the overall performance and reliability of the connector and extending the service life of the connector.

[0053] like Figure 4 As shown, a sliding groove 210 is provided on the side of the bottom of the connecting rod of the arc-shaped swing rod 207 of this embodiment, a sliding base 211 is slidably connected in the sliding groove 210, a first L-shaped push rod 213 is rotatably connected inside the sliding base 211, and a guide block 212 is sleeved on the outer surface of the first L-shaped push rod 213.

[0054] Specifically, when the arc-shaped swing arm 207 swings around the first fixed axis 208, since the arc-shaped gear and the connecting rod of the arc-shaped swing arm 207 are in a straight line, the swing direction of the arc-shaped gear at the bottom of the connecting rod always remains opposite. When the arc-shaped swing arm 207 swings, the first L-shaped push rod 213 is restricted by the guide block 212, which will drive the sliding base 211 connected to it for rotation to move from the middle to the bottom of the sliding groove 210 along the guide of the sliding groove 210, so that the first L-shaped push rod 213 can always maintain a linear reciprocating motion.

[0055] like Figure 5As shown, the assembled adhesion device 1 of this embodiment is internally provided with a rotating and lifting mechanism 3 for flipping and limiting, and the rotating and lifting mechanism 3 includes a fixed rod 301, and the fixed rod 301 is fixed on the top of the working frame 104, and the bottom of the inner cavity of the working frame 104 is rotatably connected with a third rotating shaft 302, and the outer ring surface of the third rotating shaft 302 is provided with a guide groove 303, and the inside of the guide groove 303 is slidably connected with a sliding block 304, and the middle part of the sliding block 304 is rotatably connected with a second connecting rod 305, and the end of the second connecting rod 305 away from the sliding block 304 is fixedly connected with a reciprocating cylinder 306, and the outer ring surface in the middle part of the reciprocating cylinder 306 is sleeved with a limiting ring 311.

[0056] Specifically, when the swing vibration mechanism 2 completes its work, the third rotating shaft 302 is rotated by starting an external motor whose output shaft is fixedly connected to the third rotating shaft 302. Since an annular guide groove is provided on the outer ring surface of the third rotating shaft 302, when the third rotating shaft 302 rotates, the sliding block 304 sliding in the guide groove 303 moves along the guide groove 303, and can further drive the reciprocating cylinder 306 to move upward along the guide of the limit ring 311 through the second connecting rod 305, thereby driving the remaining components in the rotating lifting mechanism 3 to move upward.

[0057] like Figure 5 and Figure 6 As shown, in this embodiment, a connecting block 307 is fixedly connected to the top of the reciprocating cylinder 306, and a second fixed shaft 308 is fixedly connected to the upper part of the connecting block 307. A rotating ring 309 is sleeved on the outer ring surface of the second fixed shaft 308, and a limiting plate 310 is fixedly connected to the top of the rotating ring 309.

[0058] Specifically, when the reciprocating cylinder 306 moves upward along the guide of the limit ring 311, the limit plate 310 on the top of the reciprocating cylinder 306 will also move synchronously. At this time, the fixed rod 301 fixed on the top of the working frame 104 will press against one side of the limit plate 310, thereby causing the limit plate 310 to rotate around the second fixed axis 308 through the rotating ring 309. When the limit plate 310 rotates from a horizontal state to a vertical state, since the limit plate 310 is made of silicone, it can not only block the glue on the part of the connector that needs to be coated, but also prevent the glue from adhering to the surface of the limit plate 310, thereby avoiding the appearance of an insulation layer on the outside of the connector due to the glue covering, and preventing the glue from falling off can improve the appearance quality of the product.

[0059] like Figure 7 and Figure 8As shown, a pre-drying mechanism 4 for drying is provided on the side of the assembled adhesion device 1 of this embodiment, and the pre-drying mechanism 4 includes a piston cylinder 401, which is fixedly connected to the inside of the support base 102, and an inner cavity is opened inside the piston cylinder 401. A movable piston 402 is slidably connected to the side wall of the inner cavity of the piston cylinder 401, and a reciprocating spring 403 is fixedly connected to the side of the movable piston 402 close to the support base 102, and the end of the reciprocating spring 403 away from the movable piston 402 is fixedly connected to the side wall of the inner cavity of the piston cylinder 401, and a reciprocating sliding rod 404 is fixedly connected to the middle part of the side of the movable piston 402 close to the support base 102, and the reciprocating sliding rod 404 slides through the side wall of the piston cylinder 401, and a second L-shaped pushing rod 405 is fixedly connected to the end of the outer annular surface of the reciprocating sliding rod 404 away from the movable piston 402, and the second L-shaped pushing rod 405 slides through the inside of the support base 102.

[0060] Specifically, the first L-shaped push rod 213 can always maintain linear motion under the swing of the arc-shaped swing rod 207 due to the cooperation of the sliding groove 210 and the guide block 212. During the movement of the first L-shaped push rod 213, it will fit with the end surface of the second L-shaped push rod 405, so that the second L-shaped push rod 405 can move along the guide port opened inside the support base 102. When the second L-shaped push rod 405 moves away from the working frame 104, it will pull the reciprocating sliding rod 404 to move away from the working frame 104. At this time, the reciprocating sliding rod 404 fixed on the bottom of the inner cavity of the moving piston 402 and the piston cylinder 401 The reciprocating spring 403 between the two parts is in a compressed state, and when the reciprocating sliding rod 404 moves, the piston cylinder 401 will suck air into the inner cavity of the piston cylinder 401 through the nozzle. When the first L-shaped push rod 213 does not fit the end surface of the second L-shaped push rod 405 under the swing of the arc-shaped swing rod 207, the reciprocating spring 403 will reset. At this time, the air stored in the piston cylinder 401 will be blown to the glue in the coating area of ​​the connector through the nozzle, so as to achieve preliminary drying of the glue, and then promote the glue to reach the initial curing state faster, which helps to shorten the entire production cycle and improve production efficiency.

[0061] Embodiment 2

[0062] like Figures 1 to 9 As shown, compared with Example 1, another embodiment of the present invention is: an automatic assembly device for new energy vehicle connectors, the specific steps include:

[0063] Raw material loading: placing connectors that meet quality requirements into the working frame 104;

[0064] Glue coating: When the connector is placed inside the working frame 104, the coating nozzle 105 is reciprocated to work on the part of the connector that needs to be coated. The wave structure of the reciprocating vibration plate 209 close to the working frame 104 is set. When the reciprocating vibration plate 209 moves, its wave structure will vibrate with the wave plate 214, so that the glue coating can be more uniform;

[0065] Parts assembly: Install the parts onto the connector one by one according to the predetermined assembly sequence. Then, use the corresponding automated equipment to process the parts that need to be crimped, welded or fastened.

[0066] Quality inspection: First, the assembled connector is visually inspected through a visual inspection system or manual inspection. Second, the electrical performance and sealing performance of the connector are tested using professional testing equipment to ensure that it meets relevant standards and requirements.

[0067] The specific method of glue coating is to first place the connector that meets the quality requirements into the working frame 104. At this time, the coating nozzle 105 will move along the guide on the top of the working table 101, and the connector can be coated while moving. When the coating work on one side of the connector is completed, the driving source 202 will start. When the driving source 202 is started, the second rotating shaft 204 fixedly connected to its output shaft will rotate, and then the first connecting rod 205 and the moving column 206 will rotate. Since the moving column 206 slides in an arc swing, The arc-shaped swing rod 207 is in the groove in the middle of the rod 207, so the arc-shaped swing rod 207 will swing, which will drive the arc-shaped gear on the top of the arc-shaped swing rod 207 to rotate in a small range. At this time, the reciprocating vibration plate 209 meshing with the arc-shaped gear on the top of the arc-shaped swing rod 207 will move back and forth in a straight line along the guide openings set on both sides of the limiting rectangular frame 203. At this time, the wave-shaped structure in the reciprocating vibration plate 209 will vibrate in coordination with the wave plate 214, so that the glue coated on the coating part of the connector can flow to every corner of the coating part of the connector.

[0068] Working principle: the limiting rectangular frame 203 fixed on the top of the support frame 201 is used to limit and guide the subsequent device, and the wave plate 214 fixed on the side wall of the workbench 101 will cooperate with the subsequent device to complete the vibration of the working frame 104.

[0069] When the coating nozzle 105 completes coating, the driving source 202 is started. When the driving source 202 is turned on, the second rotating shaft 204 fixed on the output shaft of the driving source 202 rotates synchronously. When the second rotating shaft 204 rotates, it drives the first connecting rod 205 away from the end of the driving source 202 to rotate, and at the same time drives the moving column 206 fixed at the bottom of the first connecting rod 205 to rotate, and the moving column 206 slides in the guide groove opened in the middle of the arc-shaped swing rod 207, and the guide groove opened in the middle of the arc-shaped swing rod 207 can cooperate with subsequent devices to convert the rotation of the arc-shaped swing rod 207 into swinging.

[0070] When the motion column 206 rotates, since the middle part of the arc-shaped swing arm 207 has a first fixed axis 208 fixed to the side of the driving source 202 and the arc-shaped swing arm 207 is in a rotational relationship with the first fixed axis 208, when the motion column 206 rotates around the second rotation axis 204, the arc-shaped swing arm 207 will swing. At the same time, since the arc-shaped swing arm 207 is composed of an arc-shaped gear and a connecting rod, when the arc-shaped swing arm 207 swings, the arc-shaped gear on its upper part will drive the reciprocating vibration plate 209 meshing with it to move linearly along the guide opening on the side of the limiting rectangular frame 203. At the same time, since the side of the reciprocating vibration plate 209 is adapted to the wavy structure of the wave plate 214, the reciprocating vibration plate 209 will vibrate the working frame 104 when it reciprocates, so that the glue can be evenly coated on the coating area required by the connector to improve the sealing of the connector, thereby ensuring the overall performance and reliability of the connector and extending the service life of the connector.

[0071] When the arc-shaped swing arm 207 swings around the first fixed axis 208, since the arc-shaped gear and the connecting rod of the arc-shaped swing arm 207 are in a straight line, the swing direction of the arc-shaped gear at the bottom of the connecting rod always remains opposite. When the arc-shaped swing arm 207 swings, the first L-shaped push rod 213 is restricted by the guide block 212, which will drive the sliding base 211 connected to it for rotation to move from the middle to the bottom of the sliding groove 210 along the guide of the sliding groove 210, so that the first L-shaped push rod 213 can always maintain a linear reciprocating motion.

[0072] When the swing vibration mechanism 2 completes its work, the third rotating shaft 302 is rotated by starting an external motor whose output shaft is fixedly connected to the third rotating shaft 302. Since an annular guide groove 303 is provided on the outer ring surface of the third rotating shaft 302, when the third rotating shaft 302 rotates, the sliding block 304 sliding in the guide groove 303 moves along the guide groove 303, and can further drive the reciprocating cylinder 306 to move upward along the guide of the limit ring 311 through the second connecting rod 305, thereby driving the remaining components in the rotating lifting mechanism 3 to move upward.

[0073] When the reciprocating cylinder 306 moves upward along the guide of the limit ring 311, the limit plate 310 on the top of the reciprocating cylinder 306 will also move synchronously. At this time, the fixed rod 301 fixed on the top of the working frame 104 will press against one side of the limit plate 310, so that the limit plate 310 can rotate around the second fixed axis 308 through the rotating ring 309. When the limit plate 310 rotates from a horizontal state to a vertical state, since the limit plate 310 is made of silicone, it can not only block the glue on the part of the connector that needs to be coated, but also prevent the glue from adhering to the surface of the limit plate 310, thereby avoiding the appearance of an insulation layer on the outside of the connector due to the glue covering, and preventing the glue from falling off can improve the appearance quality of the product.

[0074] The first L-shaped push rod 213 can always maintain linear motion under the swing of the arc-shaped swing rod 207 due to the cooperation of the sliding groove 210 and the guide block 212. During the movement of the first L-shaped push rod 213, it will fit with the end surface of the second L-shaped push rod 405, so that the second L-shaped push rod 405 can move along the guide opening opened inside the support base 102. When the second L-shaped push rod 405 moves away from the working frame 104, it will pull the reciprocating sliding rod 404 to move away from the working frame 104. At this time, it is fixed between the moving piston 402 and the bottom of the inner cavity of the piston cylinder 401. The reciprocating spring 403 is in a compressed state, and when the reciprocating sliding rod 404 moves, the piston cylinder 401 will suck air into the inner cavity of the piston cylinder 401 through the nozzle. When the first L-shaped push rod 213 does not fit the end surface of the second L-shaped push rod 405 under the swing of the arc-shaped swing rod 207, the reciprocating spring 403 will reset. At this time, the air stored in the piston cylinder 401 will be blown onto the glue in the connector coating area through the nozzle, so as to achieve preliminary drying of the glue, and then promote the glue to reach the initial curing state faster, which helps to shorten the entire production cycle and improve production efficiency.

The wave structure of the reciprocating vibration plate (209) is arranged on one side close to the working frame (104). When the reciprocating vibration plate (209) moves, the wave structure thereof vibrates with the wave plate (214), thereby making the glue coating more uniform. Parts assembly: Install the parts onto the connector one by one according to the predetermined assembly sequence. Then, use the corresponding automated equipment to process the parts that need to be crimped, welded or fastened. Quality inspection: First, the assembled connector is visually inspected by a visual inspection system or manual inspection.
