Description

Technical Field

[0001] The present invention relates to the technical field of security product production, in particular to automatic assembly equipment for a base spring and rear cover of a security product. Background Art

[0002] Smart cameras are a type of security product. The finished base needs to be assembled using automatic assembly equipment during production. The finished base mainly includes base raw materials, connecting rods, ball heads, spring seats, springs, and back cover bodies. During assembly, the base raw materials are placed on the jig assembly for transportation. Then, the connecting rod and ball head are assembled with the base raw materials through the ball head assembly module to form a semi-finished base. Then, the spring seat and spring are assembled with the semi-finished base through the spring assembly assembly module. Finally, the back cover body is placed on top of the semi-finished base through the back cover material tray loading three-axis assembly and pressed.

[0003] However, when the existing security product base spring back cover automatic assembly equipment is in use, when the back cover body and the base raw material are pressed together, the base is easily not placed in place during the previous assembly and transportation process. At the same time, it is easy to shake during pressing, which affects the quality of pressing. In addition, a back cover through hole is provided on the back cover body, and a boss through hole is provided on the base raw material. After the back cover body is placed on the top of the base semi-finished product through the back cover material tray loading three-axis assembly, the back cover body is easily offset, resulting in the back cover through hole and the boss through hole not being aligned, which will also affect the quality of pressing, and then affect the assembly quality of the base finished product.

At the same time, it is detected whether the base material 1201 is tilted, and the base material 1201 can be pressed to prevent it from shaking; before pressing, the position of the back cover body 1206 can be fine-tuned to ensure that the back cover through hole 1209 can be aligned with the boss through hole 1208, and the back cover body 1206 and the base material 1201 can be prevented from shaking, thereby ensuring the quality of pressing and then ensuring the assembly quality of the base finished product 12.

[0034] The clamping mechanism includes a rotating ring 201 rotatably connected to the bottom of the L-shaped plate 1104, and the bottom of the rotating ring 201 is fixedly connected to two symmetrically arranged fixed tubes 202, each of which is inserted with an extrusion rod 203, and the side wall of the fixed tube 202 is fixedly connected with an L-shaped tube 204, the L-shaped tube 204 and the fixed tube 202 are filled with hydraulic oil, the L-shaped tube 204 is inserted with a counterweight plate 205, and the side wall of each fixed tube 202 is provided with a The first detection mechanism for detection, the rotation of the rotating ring 201 is driven by the driving mechanism, the pressing cylinder 1102 is started, so that the moving block 1103 moves downward, and when the lower end of the extrusion rod 203 is against the top of the base material 1201, the extrusion rod 203 can move upward along the fixed tube 202. At the same time, under the action of hydraulic pressure, the counterweight plate 205 is pushed to move upward along the L-shaped tube 204, thereby ensuring that the extrusion force between the extrusion rod 203 and the base material 1201 is constant.

[0035] The pushing mechanism includes a plurality of first triangular blocks 301 and a plurality of second triangular blocks 304 fixedly connected to the side wall of the L-shaped plate 1104, wherein the first triangular block 301 includes two symmetrically arranged first inclined surfaces 302, and the second triangular block 304 includes two symmetrically arranged second inclined surfaces 305. The top of the movable plate 1113 is connected to the pushing rod 303 by a rotating mechanism. When the L-shaped plate 1104 moves downward, the movable plate 1113 and the movable rod 1107 can be driven to move downward synchronously by the rotating disk 1106 and the reset mechanism. When the position of the rear cover body 1206 is offset, the movable rod 303 is rotated. The ball 1110 at the lower end of 1107 will abut against the top of the rear cover body 1206, so that the moving rod 1107 cannot continue to move downward. At this time, it can push the moving plate 1113 to move upward along the side wall of the T-shaped guide rod 701. At the same time, the first return spring 702 is compressed, and when the moving plate 1113 moves upward, the pushing rod 303 is driven to move upward synchronously through the rotating mechanism. When the pushing rod 303 abuts against the first inclined surface 302 at the bottom of the first triangular block 301, the side walls of the fixed rod 1001 and the limiting rod 1002 abut against each other. At this time, the pushing rod 303 and the rotating rod 402 will not rotate, and can The push rod 303 is pushed to slide along the first inclined surface 302, thereby driving the rotating disk 1106 to rotate clockwise in the circular hole 1105 through the rotating mechanism and the movable plate 1113. When the push rod 303 slides to the second inclined surface 305 at the bottom of the second triangular block 304, it can slide along the second inclined surface 305, thereby driving the rotating disk 1106 to rotate counterclockwise in the circular hole 1105. This reciprocating process can make the rotating disk 1106 rotate back and forth within a certain range and drive the movable rod 1107 to rotate synchronously. When the movable rod 1107 is aligned with the through hole 1209 of the rear cover, the reset mechanism Under the action of , the moving rod 1107 can be inserted into the rear cover through hole 1209. At the same time, the push plate 1108 and the inclined plate 1109 are driven to move downward through the telescopic mechanism, and the inclined plate 1109 can be abutted against the top of the rear cover through hole 1209, so that the rear cover body 1206 can be rotated and adjusted. In addition, the push plate 1108 and the inclined plate 1109 penetrate into the rear cover through hole 1209 and the boss through hole 1208. Under the action of the telescopic mechanism, the push plate 1108 is abutted against the inner walls of the rear cover through hole 1209 and the boss through hole 1208, ensuring that the rear cover through hole 1209 is aligned with the boss through hole 1208.

[0036] The rotating mechanism includes a U-shaped block 401 fixedly connected to the top of the moving plate 1113, and the side wall of the U-shaped block 401 is rotatably connected to the rotating rod 402, one end of the push rod 303 is fixed to the side wall of the rotating rod 402, and the side wall of the U-shaped block 401 is provided with a limiting mechanism for limiting the rotation of the rotating rod 402. When the moving plate 1113 moves upward, the pushing rod 303 is driven to move upward synchronously through the rotating mechanism. When the pushing rod 303 is aligned with the first triangular block 30 When the first inclined surface 302 at the bottom of the rear cover abuts against the first inclined surface 302, the side walls of the fixing rod 1001 and the limiting rod 1002 abut against each other. At this time, the pushing rod 303 and the rotating rod 402 will not rotate. When the moving rod 1107 is inserted into the through hole 1209 of the rear cover and the moving plate 1113 moves downward, the pushing rod 303 can rotate upward along the rotating rod 402, so that it will not abut against the first inclined surface 302 and the second inclined surface 305, thereby preventing the rotating disk 1106 from rotating.

[0037] The limiting mechanism includes a limiting rod 1002 fixedly connected to the side wall of the U-shaped block 401, and the side wall of the rotating rod 402 is fixedly connected to the fixing rod 1001, ensuring that the rotating rod 402 and the pushing rod 303 can only rotate upward.

[0038] The first detection mechanism includes a scale mark 501 set on the side wall of the extrusion rod 203, an L-shaped frame 502 is fixedly connected to the side wall of the fixed tube 202, and a visual sensor 503 is fixedly inserted into the side wall of the L-shaped frame 502. The scale marks 501 exposed on the two extrusion rods 203 are detected by the visual sensor 503. When there is always an error between the two scale marks 501, it means that the base material 1201 is still tilted after flattening. At this time, the operator is reminded to perform maintenance.

[0039] The driving mechanism includes a motor 901 fixedly connected to the top of the L-shaped plate 1104, and the lower end of the motor 901 passes through the bottom of the L-shaped plate 1104 and is fixedly connected to the rubber wheel 902. When the motor 901 is started, the rotation of the motor 901 drives the rotation of the rubber wheel 902, thereby driving the rotation of the rotating ring 201, and then driving the rotation of the fixed tube 202 and the extrusion rod 203. At this time, the base material 1201 can be flattened to ensure that it is placed in place.

[0040] A second detection mechanism for detecting the movement of the movable plate 1113 is provided at the top of the L-shaped plate 1104, and the second detection mechanism includes a detection block 601 fixedly connected to the top of the U-shaped block 401, and an L-shaped mounting bracket 602 is fixedly connected to the top of the L-shaped plate 1104, and a distance sensor 603 is fixedly connected to the bottom of the mounting bracket 602. When the rotating disk 1106 rotates, when the distance sensor 603 detects that the movable plate 1113 has not moved downward, it indicates that the movable rod 1107 has not been able to be inserted into the rear cover through hole 1209. At this time, the operator is reminded to perform maintenance.

[0041] The reset mechanism includes two symmetrically arranged T-shaped guide rods 701 fixedly connected to the top of the rotating disk 1106, and the movable plate 1113 is sleeved on the side wall of the T-shaped guide rod 701, and the side wall of each T-shaped guide rod 701 is sleeved with a first reset spring 702, which guides and resets the movement of the movable plate 1113.

[0042] The telescopic mechanism includes two symmetrically arranged sleeve rods 801 fixedly connected to the side walls of each push plate 1108, and the side wall of each sleeve rod 801 is sleeved with a sleeve 802, the other end of the sleeve 802 is fixed to the side wall of the moving rod 1107, and the side wall of each sleeve 802 is sleeved with a second return spring 803. When the moving rod 1107 is inserted into the rear cover through hole 1209, the inclined plate 1109 can be abutted against the top of the rear cover through hole 1209, so that the rear cover body 1206 can be rotated and adjusted, and the push plate 1108 and the inclined plate 1109 are inserted into the rear cover through hole 1209 and the boss through hole 1208. At the same time, the second return spring 803 is compressed to ensure the positioning effect.

[0043] Working principle: During assembly, the base raw material 1201 is first placed on the jig assembly 105 and positioned through the boss through-hole 1208. Then, the jig assembly 105 and the base raw material 1201 are conveyed through the double-layer jig return line assembly 104. When they are conveyed to the ball head assembly assembly module 106, the conveying is stopped. The ball head assembly assembly module 106 can be used to assemble the connecting rod 1202 and the ball head 1203 with the base raw material 1201 through bolts. The assembled base semi-finished product continues to be conveyed forward and stops when it is conveyed to the ball head assembly module 106. The spring assembly assembly module 107 can be used to assemble the spring seat 1204 and the spring 1205 with the base semi-finished product. After assembly, it continues to be conveyed forward. When it is conveyed to the back cover assembly module, the back cover body 1206 is placed on the top of the base semi-finished product through the back cover material tray loading three-axis assembly 108.

[0044] Next, the pressing cylinder 1102 is started to move the moving block 1103 downward. When the lower end of the extrusion rod 203 contacts the top of the base material 1201, the extrusion rod 203 can move upward along the fixed tube 202. At the same time, under the action of the hydraulic pressure, the counterweight plate 205 is pushed to move upward along the L-shaped tube 204, thereby ensuring that the extrusion force between the extrusion rod 203 and the base material 1201 is constant. At the same time, the motor 901 is started. The rotation of the motor 901 drives the rotation of the rubber wheel 902, thereby driving the rotation of the rotating ring 201, and then driving the fixed tube 202 and the extrusion rod 203. 03 is rotated. At this time, the base material 1201 can be flattened to ensure that it is placed in place, and the scale marks 501 exposed on the two extrusion rods 203 are detected by the visual sensor 503. When there is always an error between the two scale marks 501, it means that the base material 1201 is still tilted after being flattened. At this time, the operator is reminded to perform maintenance. In the subsequent pressing process, the base material 1201 is pressed tightly by the extrusion rod 203 to prevent it from shaking, thereby ensuring the quality of the subsequent pressing and further ensuring the assembly quality of the base finished product 12;

[0045] At the same time, when the L-shaped plate 1104 moves downward, the movable plate 1113 and the movable rod 1107 can be driven to move downward synchronously through the rotating disk 1106 and the reset mechanism. When the position of the rear cover body 1206 is offset, the ball 1110 at the lower end of the movable rod 1107 will be against the top of the rear cover body 1206, so that the movable rod 1107 cannot continue to move downward. At this time, the movable plate 1113 can be pushed to move upward along the side wall of the T-shaped guide rod 701. At the same time, the first reset spring 702 is compressed, and when the movable plate 1113 moves upward, the push rod 303 is driven to move upward synchronously through the rotating mechanism. When the push rod 303 is aligned with the first inclined surface at the bottom of the first triangle block 301, When the first and second cams 305 are in contact with each other, the side walls of the fixed rod 1001 and the limiting rod 1002 are in contact with each other. At this time, the pushing rod 303 and the rotating rod 402 will not rotate, and the pushing rod 303 can be pushed to slide along the first inclined surface 302, thereby driving the rotating disk 1106 to rotate clockwise in the circular hole 1105 through the rotating mechanism and the movable plate 1113. When the pushing rod 303 slides to the second inclined surface 305 at the bottom of the second triangular block 304, it can slide along the second inclined surface 305, thereby driving the rotating disk 1106 to rotate counterclockwise in the circular hole 1105. This reciprocating process can make the rotating disk 1106 rotate back and forth within a certain range and drive the moving rod 1107 to rotate synchronously.

[0046] When the moving rod 1107 is aligned with the rear cover through hole 1209, under the action of the first return spring 702, the moving rod 1107 can be inserted into the rear cover through hole 1209, and the moving plate 1113 moves downward. At the same time, the push plate 1108 and the inclined plate 1109 are driven downward by the telescopic mechanism. At this time, the push rod 303 can rotate upward along the rotating rod 402 so that it will not collide with the first inclined surface 302 and the second inclined surface 305, thereby not pushing the rotating disk 1106. The rear cover body 1206 is rotated, and the inclined plate 1109 is abutted against the top of the rear cover through-hole 1209, so that the rear cover body 1206 can be rotated and adjusted. In addition, the push plate 1108 and the inclined plate 1109 are inserted into the rear cover through-hole 1209 and the boss through-hole 1208. At the same time, the second return spring 803 is compressed, so that the push plate 1108 is abutted against the inner walls of the rear cover through-hole 1209 and the boss through-hole 1208, ensuring that the rear cover through-hole 1209 and the boss through-hole 1208 are aligned.

[0047] When the pressing ring 1112 abuts against the top of the rear cover body 1206, the rear cover body 1206 and the base raw material 1201 can be pressed together. Therefore, before pressing together, the position of the rear cover body 1206 can be fine-tuned to ensure that the rear cover through hole 1209 is aligned with the boss through hole 1208. In addition, under the squeezing action of the second return spring 803, the rear cover body 1206 and the base raw material 1201 can be prevented from shaking, thereby ensuring the quality of pressing together and further ensuring the assembly quality of the finished base 12.

[0048] After the assembly is completed, the finished base 12 is transported out through the discharge port 103 and is manually unloaded and inspected.
