Description

Technical Field

[0001] The present application relates to the field of component assembly, and in particular to a vacuum negative pressure detection and assembly mechanism. Background Art

[0002] As people's living standards improve, the overall performance and configuration of automobiles have greatly improved. Currently, most cars are equipped with air conditioning systems, and airflow control components are installed on the air outlets of the car air conditioner to adjust the airflow direction. The airflow control components can deliver cold or warm air to every corner of the car, ensuring that all passengers can enjoy the benefits of air conditioning.

[0003] like Figure 1 and Figure 2 As shown, the wind direction adjustment member 0 includes a blade 01, a fixed bracket 1 02, a connecting rod 03 and a fixed bracket 2 04. One end of the blade 01 is fixedly connected to a boss 1 011 and a boss 2 012, and the other end of the blade 01 is fixedly connected to a boss 3 013. The fixed bracket 1 02 is provided with an assembly port 1 021 for plugging with the boss 1 011, the connecting rod 03 is provided with an assembly port 2 031 for plugging with the boss 2 012, and the fixed bracket 2 04 is provided with an assembly port 3 041 for plugging with the boss 3 013. The blade 01 is installed on the fixed bracket 1 02, the connecting rod 03 and the fixed bracket 2 04 through the assembly mechanism. One side of the fixed bracket 1 02, the connecting rod 03 and the fixed bracket 2 04 is fixedly connected to a boss 022. During installation, it is necessary to ensure that the boss 022 is close to the blade 01 to complete the assembly.

[0004] In order to prevent the fixed bracket from being installed upside down, the existing assembly mechanism has designed error-proofing structures such as mechanical error-proofing structures, infrared error-proofing structures, and optical fiber error-proofing structures. These error-proofing structures can detect whether the fixed bracket is installed upside down. However, because the fixed bracket is relatively thin, during the actual production process, some fixed brackets themselves will warp or have poor dimensions. The existing error-proofing structures cannot detect and alarm in time, which will cause errors in the assembly process of the fixed bracket and the blade, ultimately resulting in product scrapping and reduced production efficiency. Summary of the Invention

[0005] In order to improve production efficiency, the present application provides a vacuum negative pressure detection assembly mechanism.

[0006] The vacuum negative pressure detection assembly mechanism provided in this application adopts the following technical solutions:

[0007] A vacuum negative pressure detection assembly mechanism includes an assembly table, a base and an adsorption block. The base is slidably connected to the upper end of the assembly table, and the adsorption block is fixedly connected to the side wall of the base. An adsorption groove is provided at the end of the adsorption block facing away from the base. The adsorption groove is used for placing a fixed bracket. The bottom of the adsorption groove is provided with an adsorption port, and the adsorption port is used to adsorb the fixed bracket.

[0008] By adopting the above technical solution, when installing the fixed bracket, if the fixed bracket is installed upside down, the boss side will be close to the bottom of the adsorption groove, and there will be a gap of the boss thickness between the fixed bracket and the bottom of the adsorption groove. If the fixed bracket is warped or has poor size, the fixed bracket will not fit the bottom of the adsorption groove, and the pressure of the adsorption port will not reach the preset value. It is easy to quickly detect whether the fixed bracket meets the requirements and whether the fixed bracket is installed upside down, thereby improving processing efficiency.

[0009] Preferably, it also includes a placement table, which is arranged on the side of the adsorption block away from the base, and the placement table is fixedly connected to the upper end of the assembly table. The upper end of the placement table is provided with a slot, and the slot extends to both ends to pass through the placement table. The length direction of the slot is parallel to the sliding direction of the base, and the slot is used to insert the blade.

[0010] By adopting the above technical solution, the slot limits the placement of the blade, thereby improving the stability of the blade, and the base moves closer to the placement table, which facilitates the assembly of the fixed bracket and the blade, thereby improving assembly efficiency.

[0011] Preferably, it also includes an air pipe, a vacuum generator, a controller and an indicator light. The upper end of the adsorption block is provided with an air outlet, the air outlet is connected to the adsorption port, one end of the air pipe is coaxially fixedly connected to the inner wall of the air outlet, and the other end of the air pipe is coaxially fixedly connected to the inner wall of the air inlet of the vacuum generator. An air pressure sensor is fixedly connected to the vacuum generator, the controller is electrically connected to the air pressure sensor, and the controller is electrically connected to the indicator light.

[0012] By adopting the above technical solution, the air pressure sensor detects the negative pressure of the adsorption port and sends a signal to the controller. The controller compares the detection value with the preset value. If the detection value is less than or equal to the preset value, it indicates that the installation of the fixed bracket meets the requirements, the indicator light comes on, and the base slides close to the placement table. After the assembly is completed, the base moves away from the placement table and the indicator light goes off, which makes it easy for the operator to judge whether the quality of the fixed bracket meets the requirements and whether the fixed bracket is installed in place, thereby improving processing efficiency.

[0013] Preferably, it also includes a push rod, the assembly table is provided with a through opening, the through opening vertically passes through the assembly table, the push rod slides in the through opening, the push rod is used to limit the base, when the fixed bracket and the blade are assembled, the push rod is arranged on the side of the base away from the placement table.

[0014] By adopting the above technical solution, if the pressure of the adsorption port does not drop below the preset value, the push rod extends upward from the opening to limit the sliding of the base, reminding the operator that the fixing bracket is of poor quality or is not placed correctly. When the pressure of the adsorption port drops below the preset value, the push rod moves downward and the base slides smoothly close to the placement table.

[0015] Preferably, it also includes a driving cylinder and a reset rod, the cylinder body of the driving cylinder is fixedly connected to the lower end of the assembly table, the piston rod of the driving cylinder is coaxially fixedly connected to the lower end of the push rod, the reset rod is coaxially fixedly connected to the piston rod of the driving cylinder, the reset rod is arranged below the cylinder body of the driving cylinder, and the driving cylinder is electrically connected to the controller.

[0016] By adopting the above technical solution, the controller controls the up and down sliding of the push rod by controlling the driving cylinder, so that the position of the push rod can be adjusted according to the pressure of the adsorption port, so that when the fixed bracket is not installed in place, the sliding of the base is blocked by the push rod. When the fixed bracket is installed correctly, the base can slide smoothly. If the base slides between the push rod and the placement table, the base can be reset only when the fixed bracket and the blade are installed. The reset rod allows the user to manually control the downward movement of the push rod.

[0017] Preferably, it also includes a distance sensor, which is arranged between the base and the placement table. The distance sensor is used to detect the distance from the detection head to the base. The distance sensor is electrically connected to the controller, and the distance sensor sends a signal to the controller.

[0018] By adopting the above technical solution, the distance sensor is used to detect the position of the base, thereby determining the relative position of the fixed bracket and the blade, so that when the fixed bracket is not installed on the adsorption block, the base cannot approach the placement table, and when the fixed bracket on the adsorption block is not assembled with the blade, the base cannot move away from the placement table.

[0019] Preferably, it also includes a quick clamp, which includes a fixed seat, a guide seat, a hinged seat, a guide rod, a first connecting rod, a second connecting rod and a handle, wherein the fixed seat is arranged on a side of the base away from the adsorption block, the fixed seat is fixedly connected to the upper end of the assembly table, the guide seat and the hinged seat are both fixedly connected to the upper end of the fixed seat, the hinged seat is arranged on a side of the guide seat away from the base, the guide seat is provided with a guide port, the axis of the guide port is parallel to the sliding direction of the base, the guide rod is slidably connected to the inner wall of the guide port, one end of the guide rod is fixedly connected to the base, the other end of the guide rod is hinged to one end of the first connecting rod, the other end of the first connecting rod is hinged to one end of the second connecting rod, the other end of the second connecting rod is hinged to the hinged seat, and the handle is fixedly connected to the end of the second connecting rod away from the fixed seat.

[0020] By adopting the above technical solution, it is easy to control the movement of the base and improve the operating efficiency.

[0021] Preferably, a positioning pin is further included. The bottom of the adsorption groove is provided with a positioning groove. The positioning pin is connected to the groove wall of the positioning groove. The positioning pin is used to be inserted into the hole of the fixing bracket.

[0022] By adopting the above technical solution, the fixed bracket is hung on the positioning pin, which improves the installation efficiency of the fixed bracket, reduces the probability of the fixed bracket falling when the vacuum generator is not started, improves user operation efficiency, and then improves detection efficiency.

[0023] Preferably, it further comprises a first spring, one end of the first spring is fixedly connected to the bottom of the positioning groove, and the other end of the first spring is fixedly connected to the positioning needle.

[0024] By adopting the above technical solution, the fixed bracket is hung on the positioning pin. When the fixed bracket is assembled with the blade, the protruding column abuts against the positioning pin, causing the positioning pin to move toward the bottom of the positioning groove. After the fixed bracket and the blade are assembled, the base is away from the blade, and the first spring resets the positioning pin, making it easier for the next fixed bracket to be hung, thereby improving the installation efficiency of the fixed bracket.

[0025] Preferably, it also includes an abutment column, a gear, a first rack and a second rack, the bottom of the adsorption groove is provided with an abutment groove, the abutment groove is provided between the positioning groove and the adsorption port, the abutment column is slidably connected to the bottom of the abutment groove, the adsorption block is provided with a connecting cavity, the connecting cavity is provided between the positioning groove and the adsorption groove, the gear rotates around its own axis and is connected to the inner wall of the connecting cavity, the rotation axis of the gear is set, the first rack is fixedly connected to the positioning pin, the second rack is fixedly connected to the abutment column, and the first rack and the second rack are respectively engaged with the two ends of the gear.

[0026] By adopting the above technical solution, while the positioning pin moves, the abutment column moves in the opposite direction, pushing the fixing bracket to fix the blade, thereby improving assembly efficiency and assembly quality.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] 1. When installing the fixed bracket, if the fixed bracket is installed upside down, the boss side will be close to the bottom of the adsorption groove. There will be a gap of the boss thickness between the fixed bracket and the bottom of the adsorption groove. If the fixed bracket is warped or has poor dimensions, the fixed bracket will not fit the bottom of the adsorption groove, which will cause the pressure of the adsorption port to fail to reach the preset value. It is easy to quickly detect whether the fixed bracket meets the requirements and whether the fixed bracket is installed upside down, thereby improving processing efficiency.

[0029] 2. The air pressure sensor detects the negative pressure at the suction port and sends a signal to the controller. The controller compares the detected value with the preset value. If the detected value is less than or equal to the preset value, it indicates that the installation of the fixed bracket meets the requirements. The indicator light comes on and the base slides closer to the placement table. After the assembly is completed, the base moves away from the placement table and the indicator light goes off. This makes it easy for the operator to judge whether the quality of the fixed bracket meets the requirements and whether the fixed bracket is installed in place, thereby improving processing efficiency.

[0030] 3. The controller controls the up and down sliding of the ejector pin by controlling the driving cylinder, so as to adjust the position of the ejector pin according to the pressure of the adsorption port. When the fixed bracket is not installed in place, the sliding of the base is blocked by the ejector pin. When the fixed bracket is installed correctly, the base can slide smoothly. If the base slides between the ejector pin and the placement table, the base can be reset only when the fixed bracket and the blade are installed. The reset rod allows the user to manually control the downward movement of the ejector pin. BRIEF DESCRIPTION OF THE DRAWINGS

The end of the adsorption block 32 facing away from the base 31 is provided with an adsorption groove 321 for placing a fixed bracket. The adsorption groove 321 is provided with an adsorption port 3211 at the bottom of the adsorption groove 321 for adsorbing the fixed bracket. The upper end of the adsorption block 32 is provided with an air outlet 322, which is connected to the adsorption port 3211.

The indicator light 45 lights up, and the driving cylinder 422 drives the push rod 421 to rise to prevent the base 31 from resetting. If the detection value of the air pressure sensor 413 is greater than the preset value, it indicates that the fixing bracket is assembled with the blade, and the fixing bracket is separated from the adsorption groove 321.

When the fixing bracket and the blade are assembled, the boss pushes the positioning pin 461 to move. When the positioning pin 461 moves toward the bottom of the positioning groove 3212, the blocking block 469 moves toward the air outlet 322. The abutment column 463 pushes the fixing bracket and the blade into contact. When the positioning pin 461 moves away from the bottom of the positioning groove 3212, the blocking block 469 moves away from the air outlet 322.

[0053] The implementation principle of the vacuum negative pressure detection assembly mechanism of the present application is as follows: when the distance sensor 43 detects that the base 31 is on the side of the push rod 421 away from the placement table 2, if the air pressure sensor 413 detects that the fixed bracket is installed correctly, the indicator light 45 lights up, and the driving cylinder 422 controls the push rod 421 to descend, so that the base 31 can slide closer to the placement table 2. If the fixed bracket is not installed correctly, the indicator light 45 does not light up, and the push rod 421 rises to prevent the base 31 from sliding; when the distance sensor 43 detects that the base 31 is on the side of the push rod 421 and the placement table 2, the air pressure sensor 413 detects that the fixed bracket is installed correctly, the indicator light 45 lights up, and the driving cylinder 422 controls the push rod 421 to descend, so that the base 31 can slide closer to the placement table 2. When placed between platforms 2, if the detection value of the air pressure sensor 413 is less than or equal to the preset value, it indicates that the fixed bracket is still in the adsorption groove 321 and has not been assembled with the blades. The indicator light 45 is on, and the driving cylinder 422 drives the push rod 421 to rise to prevent the base 31 from resetting. If the detection value of the air pressure sensor 413 is greater than the preset value, it indicates that the fixed bracket and the blades are completely assembled, the fixed bracket is separated from the adsorption groove 321, and the indicator light 45 is off. After the fixed brackets in the two adsorption blocks 32 are completely assembled, the push rod 421 descends, and the base 31 can slide and reset.
