Description

Technical Field

[0001] The present invention relates to a production line, in particular to an assembly and detection production line for safety sensors. Background Art

[0002] In the production of safety sensors (also known as safety sensors), during the final production stage, the sensor assembly and the bottom shell are assembled. Since the sensor assembly needs to be rigidly clipped into the bottom shell at an angle, manual clip-on assembly is generally used in the prior art to ensure production accuracy. This is time-consuming and labor-intensive, and is not conducive to production continuity. Summary of the Invention

[0003] The purpose of the present invention is to provide an assembly and testing production line for safety sensors, which can realize the automated assembly and production of sensor components and bottom shells, and at the same time can also have the automated testing effect after assembly, with better continuity and automation.

[0004] The present invention provides the following technical solutions:

[0005] An assembly and testing production line for safety sensors, comprising a first direct vibration feeder, a bottom shell flipping mechanism, an assembly indexing turntable, an optical fiber detection sensor, a second direct vibration feeder, a first quick gripper, an angle adjustment mechanism, a second quick gripper, and a pressing assembly;

[0006] The straight vibration feeder is used to feed the bottom shell, which is a prior art and will not be described in detail here. The tail end of the feeding is connected to a bottom shell turning mechanism. The bottom shell turning mechanism receives and grabs the conveyed bottom shell and sends it to a loading station corresponding to the assembly indexing turntable. There are multiple groups of carriers evenly distributed along the circumference of the outer periphery of the assembly indexing turntable. At the loading station, a group of carriers on the assembly indexing turntable receives the bottom shell sent by the bottom shell turning mechanism and rotates it to the optical fiber detection station. At the optical fiber detection station, the optical fiber detection sensor The sensor is used to detect the position of the bottom shell placed in the carrier to determine whether the bottom shell is placed in the carrier in place; at the same time, since the bottom shell loading and placement position detection are divided into different workstations, the overall work efficiency can be improved. In addition, a set of optical fiber position pressure cylinders can be set at the optical fiber detection station, that is, when the bottom shell moves to the optical fiber detection station, it can be tested at the same time, and the optical fiber position pressure cylinder can also press down the bottom shell to ensure that the bottom shell can be completely placed in the carrier cavity, thereby ensuring the accuracy of subsequent operations.

[0007] The second straight vibration feeder is used to feed the sensor assembly. It is a prior art and will not be described in detail here. The tail end of its feeding is connected to a rubbing table. After the rubbing table receives a group of sensor assemblies delivered to the position, it is driven by a rubbing cylinder to perform horizontal linear motion to form a docking misalignment with the feeding tail end of the second straight vibration feeder. The blocking plate on one side moves to the feeding tail end of the second straight vibration feeder to form a blocking effect on the sensor assembly, that is, to form a material blocking effect to prevent interference with the latter group of sensor assemblies when clamping the front end group of sensor assemblies.

[0008] The quick gripper 1 is used to grab the sensor component on the rubbing table and feed it into the grabbing end of the angle adjustment mechanism. The angle adjustment mechanism is used to dock with the grabbing end of the quick gripper 2 above after grabbing the fed sensor component and turning it over. The quick gripper 2 is used to move to the assembly station of the assembling indexing turntable after grabbing the sensor component. At the assembly station, the quick gripper 2 is used to insert the sensor component into the bottom shell at an angle to avoid the buckle in the bottom shell. Because the bottom shell is provided with a buckle for clamping and positioning the sensor component, direct vertical downward pressure will not be able to operate due to the obstruction of the buckle. Therefore, it is necessary to first plug it in in an inclined manner. , so that the sensor assembly can avoid the buckle and be placed in the bottom shell, and the setting of the angle adjustment mechanism is also used to adapt the sensor assembly to the transition between the quick gripper 1 for vertical gripping and the quick gripper 2 for inclined gripping. However, the inclined plug-in mode of the quick gripper 2 cannot complete the precise full-down operation, so a pressing station can be added to realize the vertical pressing operation, that is, after the initial inclined plug-in is completed at the assembly station, the assembly indexing turntable then drives the bottom shell assembled with the sensor assembly to rotate to the pressing station. At the pressing station, the pressing assembly is used to vertically press the sensor assembly downward so that it is completely placed in the bottom shell and its top is blocked and limited by the buckle;

[0027] The beneficial effects of the present invention are:

[0028] In the assembly and testing production line of the safety sensor of the present invention, since a buckle for clamping and positioning the sensor assembly is provided in the bottom shell, direct vertical downward pressing and plugging will not be possible due to the obstruction of the buckle. Therefore, it is necessary to first plug in in an inclined manner so that the sensor assembly can avoid the buckle and be placed in the bottom shell. The angle adjustment mechanism is also provided to adapt the transition of the sensor assembly between the vertical gripping quick gripper 1 and the inclined gripping quick gripper 2. However, the inclined plugging method of the quick gripper 2 cannot complete the precise and complete downward pressing operation. Therefore, a pressing station can be added to realize the vertical downward pressing operation. That is, after the initial inclined plugging is completed at the assembly station, the assembly indexing turntable drives the bottom shell assembled with the sensor assembly to rotate to the pressing station. At the pressing station, the pressing assembly is used to vertically press the sensor assembly so that it is completely placed in the bottom shell and its top is blocked and limited by the buckle. At this point, the automated assembly operation of the bottom shell and the sensor assembly can be completed, with better continuity and automation.

[0029] 2. The bottom shell flipping mechanism is used to realize the transition between the direct vibration feeder 1 and the bottom shell on the loading station carrier. The rubbing table, the quick gripper 1, the angle adjustment mechanism and the quick gripper 2 are used to realize the transition between the direct vibration feeder 2 and the sensor component on the bottom shell of the assembly station. After the bottom shell is loaded, an optical fiber detection station is added to judge whether the placement position of the bottom shell in the carrier is in place. At the same time, since the bottom shell loading and placement position detection are divided into different stations for operation, the overall work efficiency can be improved. In addition, a set of optical fiber detection stations can be set. Positioning cylinder, that is, when the bottom shell moves to the optical fiber detection station, it can be accompanied by detection, and at the same time, the optical fiber positioning cylinder can press down the bottom shell to ensure that the bottom shell can be completely placed in the carrier cavity, thereby ensuring the accuracy of subsequent operations. At the same time, a pressing station is added after the sensor is assembled to realize the positional operation of sensor component insertion and pressing. The refined process station also ensures that each station can work simultaneously because the assembly indexing turntable drives the indexing rotation of the carrier, and the time interval between the middle work is also short to improve production efficiency.

DETAILED DESCRIPTION

[0046] Example 1

[0047] like Figure 1-14 As shown, a safety sensor assembly and testing production line, in this embodiment, includes a straight vibration feeder 100, a bottom shell flip mechanism 200, an assembly indexing turntable 300, an optical fiber detection sensor 400, a straight vibration feeder 2 500, a quick gripper 1 600, an angle adjustment mechanism 700, a quick gripper 2 800 and a pressing assembly 900;

[0048] The straight vibration feeder 100 is used for feeding the bottom shell, which is a prior art and will not be described in detail here. The tail end of the feeding is connected to the bottom shell turning mechanism 200. The bottom shell turning mechanism 200 receives and grabs the conveyed bottom shell and sends it to a loading station corresponding to the assembly indexing turntable 300. The periphery of the assembly indexing turntable 300 is evenly distributed along the circumference. There are multiple groups of carriers 1. At the loading station, a group of carriers 1 on the assembly indexing turntable 300 receives the bottom shell sent by the bottom shell turning mechanism 200 and rotates it to the optical fiber detection station. The optical fiber detection sensor 400 is used to detect the position of the bottom shell placed in the carrier 1 to determine whether the bottom shell is in place in the carrier 1; at the same time, since the bottom shell loading and placement position detection are divided into different workstations, the overall work efficiency can be improved, and a group of optical fiber position pressure cylinders can be provided at the optical fiber detection station, that is, when the bottom shell moves to the optical fiber detection station, it can be accompanied by detection and at the same time, the optical fiber position pressure cylinder can press down the bottom shell to ensure that the bottom shell can be completely placed in the carrier cavity of the carrier 1, thereby ensuring the accuracy of subsequent operations.

[0049] The second straight vibration feeder 500 is used to feed the sensor assembly 2. It is a prior art and will not be described in detail here. The tail end of its feeding is connected to a rubbing table 501. After receiving a group of sensor assemblies 2 delivered to the position, the rubbing table 501 is driven by a rubbing cylinder 502 to perform horizontal linear motion to form a docking misalignment with the feeding tail end of the second straight vibration feeder 500. The blocking plate 503 on one side moves to the feeding tail end of the second straight vibration feeder 500 to form a blockage for the sensor assembly 2, that is, to form a material blocking effect to prevent interference with the latter group of sensor assemblies 2 when clamping the frontmost group of sensor assemblies 2;

[0050] The quick gripper 600 is used to grab the sensor assembly 2 on the rubbing table 501 and rotate it 90 degrees in the horizontal plane and then feed it into the grabbing end of the angle adjustment mechanism 700. The angle adjustment mechanism 700 grabs the fed sensor assembly 2 and flips the angle in the vertical plane to dock with the grabbing end of the quick gripper 800 above. The quick gripper 800 is used to move to the assembly station of the assembling indexing turntable 300 after grabbing the sensor assembly 2. At the assembly station, the quick gripper 800 is used to insert the sensor assembly 2 into the bottom shell at an angle to avoid the buckle in the bottom shell, because the bottom shell is provided with a buckle for clamping and positioning the sensor assembly 2. Therefore, direct vertical downward pressure will not be able to operate due to the obstruction of the buckle. Therefore, It is necessary to first plug in an inclined manner so that the sensor assembly 2 can avoid the buckle and be placed in the bottom shell, and the setting of the angle adjustment mechanism 700 is also used to adapt the sensor assembly 2 to the transition between the vertically grasped quick gripper 1 600 and the inclined grasping quick gripper 2 800. However, the inclined plugging method of the quick gripper 2 800 cannot complete the precise and complete pressing operation, so a pressing station can be added to realize the vertical pressing operation, that is, after the inclined preliminary plugging is completed at the assembly station, the assembly indexing turntable 300 then drives the bottom shell assembled with the sensor assembly 2 to rotate to the pressing station. At the pressing station, the pressing assembly 900 is used to vertically press the sensor assembly 2 downward so that it is completely placed in the bottom shell and its top is blocked and limited by the buckle.

[0051] At this point, the automated assembly operation of the bottom shell and the sensor assembly 2 can be completed with better continuity and automation.

[0052] The bottom shell flipping mechanism 200 includes a flip base 201, a flip mounting frame 202, a flip top cylinder 203, a flip driving cylinder 204 and a flip clamp 205. The flip mounting frame 202 is slidably mounted on the flip base 201, and its bottom is driven and connected to the flip top cylinder 203 on the flip base 201. The flip driving cylinder 204 on it is driven to rise and fall under the drive of the flip top cylinder 203. The rotating driving end of the flip driving cylinder 204 is connected to the flip clamp 205. The flipping clamp 205 is docked at the tail end of the straight vibration feeder 100 to clamp the conveyed bottom shell, and is driven by the flip top cylinder 203 to rise and turn 180° under the drive of the flip drive cylinder 204 and then descend again under the drive of the flip top cylinder 203 to feed the bottom shell into the carrier 1 that is rotated into place at the loading station. At this point, the transition of the bottom shell to the carrier 1 at the loading station can be realized. The whole process only requires one set of bottom shell flipping mechanisms 200, which is more convenient and more stable.

The pulley is limited in the long strip groove, and when the swing arm 606 rotates, it is driven by the swing arm 606 to move in an n-shaped manner in the groove, so as to drive the driving plate 607 fixed at its axis end to move synchronously. A group of vertical guide rails 608 are installed in the guide of the driving plate 607, and a slider 1 for sliding connection installed on the horizontal guide rail 603 is also installed on the back side thereof, and the vertical guide rail 608 is distributed perpendicular to the horizontal guide rail 603. The bottom end of the vertical guide rail 608 is also provided with a group of rotating cylinders 604 and quick clamps 609 in the direction of its guide extension. The quick clamps 609 are used to vertically grasp the sensor assembly 2 on the rubbing table 501 and are driven by the rotating cylinder 604 to rotate 90 degrees and then transition to the grasping end of the angle adjustment mechanism 700.

[0070] The working principle of the present invention is as follows: in the assembly and detection production line of the safety sensor of the present invention, since a buckle is provided in the bottom shell for clamping and positioning the sensor assembly 2, direct vertical downward pressing and plugging will not be able to operate due to the obstruction of the buckle. Therefore, it is necessary to first plug in an inclined manner so that the sensor assembly 2 can avoid the buckle and be placed in the bottom shell. The setting of the angle adjustment mechanism 700 is also used to adapt the sensor assembly 2 to the transition between the vertical grasping quick gripper 1 600 and the inclined grasping quick gripper 2 800. However, the quick gripper 2 80 0 The inclined plug-in method cannot complete the precise full pressing operation, so a pressing station can be added to realize the vertical pressing operation, that is, after completing the inclined preliminary plug-in at the assembly station, the assembly indexing turntable 300 drives the bottom shell assembled with the sensor component 2 to rotate to the pressing station. At the pressing station, the pressing assembly 900 is used to vertically press the sensor component 2 so that it is completely placed in the bottom shell and its top is blocked and limited by the buckle; at this point, the automated assembly operation of the bottom shell and the sensor component 2 can be completed, with better continuity and automation. The bottom shell flipping mechanism 200 is used to realize the transition between the direct vibration feeder 100 and the bottom shell on the loading station carrier 1, and the rubbing table 501, the quick gripper 600, the angle adjustment mechanism 700, and the quick gripper 800 are used to realize the transition between the direct vibration feeder 500 and the sensor component 2 on the bottom shell of the assembly station, and an optical fiber detection station is added after the bottom shell is loaded to determine whether the placement position of the bottom shell in the carrier 1 is in place; at the same time, since the bottom shell loading and placement position detection are divided into different stations for operation, the overall work efficiency can be improved, and at the optical fiber detection station, A group of optical fiber positioning cylinders can be provided, that is, when the bottom shell moves to the optical fiber detection station, it can be accompanied by detection and the bottom shell can be pressed down by the optical fiber positioning cylinder to ensure that the bottom shell can be completely placed in the carrier cavity of the carrier 1, thereby ensuring the accuracy of subsequent operations. At the same time, a pressing station is added after the sensor is assembled to realize the positional operation of plugging and pressing the sensor component 2. The refined process station also ensures that each station can work simultaneously because the assembly indexing turntable 300 drives the indexing rotation of the carrier, and the time interval between the middle work is also short to improve production efficiency.
