[0027] The lower casing assembly device includes a lower casing storage box 23 mounted on a frame, a lower casing conveyor belt 24, and a robot arm for gripping the lower casings. Lower casing positioning fixtures 25 are evenly distributed on the lower casing assembly tray. The robot arm is used to place the lower casings with the rotating shaft of the lower casing spring into the lower casing positioning fixtures. The robot arm is equipped with an image recognition system for identifying the number of lower casings on the conveyor belt. When there are not enough lower casings, the lower casing storage and delivery system sends the lower casings into the conveyor belt.

The measuring wheel assembly plate is evenly equipped with multiple measuring wheel base positioning seats and measuring spring positioning seats for fixing measuring wheel bases and measuring springs. A rotating shaft 12 is rotatably mounted in the middle of the measuring wheel base positioning seat, and a connecting clamp 13 is installed at the lower end of the rotating shaft 12. The measuring wheel base feeding mechanism 14, the measuring spring feeding mechanism 15, and the measuring wheel cover plate feeding mechanism 16 are installed around the measuring wheel assembly plate in sequence on the frame. A detection mechanism and a measuring spring pre-tightening mechanism are installed in sequence on the frame corresponding to the position directly below the measuring wheel base positioning seat.

After rotating a certain number of turns or angles, the servo motor stops automatically; the frame is also equipped with a ruler wheel assembly gripping unit for gripping the pre-tightened ruler wheel assembly onto the lower ruler shell assembly plate.

[0030] The upper scale shell assembly device includes an upper scale shell fixture 27 mounted on an upper scale shell assembly plate, on which an upper scale shell is mounted.

An upper scale shell gripping unit for gripping the assembled upper scale shell onto the lower scale shell assembly plate is also mounted on the frame.

[0031] The specific workflow of this production line is as follows:

[0032] Measuring tape components: Tape housing assembly (upper and lower housings) + tape wheel assembly (taper spring, tape wheel seat, and cover plate) + tape belt assembly (taper hook and tape) + measuring tape accessories (handle strap, belt buckle, tape nozzle, and tape stopper) + fixing screws. Measuring tape working principle: Under normal conditions, the tape belt is wound around the tape wheel assembly under the preload of the spring. When the tape belt is pulled out, the tape wheel rotates, and the tape spring connected to the tape wheel, along with the rotation of the tape wheel, stores energy to retract the tape belt back into the tape housing.

[0033] This automated assembly equipment is meticulously designed, taking into account the components and working principle of the measuring tape. It is roughly divided into the following equipment components.

[0034] Scale wheel assembly equipment:

[0035] (1): Loading material onto the measuring wheel

[0036] After the ruler wheel bases are straightened by the vibrating plate and the ruler wheel guide rail, they are arranged in sequence. The first one in the sequence is the position to be grasped. The ruler wheel base is grasped by the ruler wheel grasping unit and transported to the designated position on the turntable. When the sensor detects that there is no ruler wheel at the position to be grasped, the next ruler wheel base moves forward and reaches the grasping position, waiting for the next grasping unit to grasp it.

[0037] (2) Loading the spring

[0038] The vibrating rod detects that the transmission of the ruler spring from the vibrating plate is about to be completed and sends a signal to the ruler spring storage unit to add ruler springs to the vibrating plate. After the vibrating plate is straightened by vibration and the ruler spring guide rail, the springs are arranged sequentially on the guide rail. The turntable rotates, and the ruler spring grasping unit grasps the ruler springs and places them into the ruler wheel base. The turntable rotates, moving the ruler wheel base and ruler springs to the next position, awaiting the installation of the ruler wheel cover plate.

[0039] (3) Installation of the measuring wheel cover plate

[0040] The vibratory feeder for the measuring wheel cover plate feeds the material through vibration. The guide rail of the measuring wheel cover plate is straightened, so that the measuring wheel cover plates are arranged sequentially on the guide rail. The gripping unit grips the cover plate at the pre-grip position. If no cover plate is detected at the pre-grip position, the next cover plate is pushed in through the ejection device.

[0041] The measuring wheel cover plate is picked up onto the turntable and rotated and installed on the measuring wheel base.

[0042] (4) Check whether the wheels, springs and cover plates are assembled properly.

[0043] The rotating shaft drives the ruler wheel assembly and ruler spring to rotate. During rotation, the exposed end of the ruler spring is detected by the sensor, indicating that the assembly is installed correctly. Then the rotating disk rotates and moves to the next station—ruler spring pre-tensioning.

[0044] (5) Preload of the rudder spring

[0045] The servo motor is connected to the rotating shaft of the ruler spring via an upward axis. The ruler wheel assembly, detected as properly installed and rotating slowly in the previous station, pre-tightens the ruler spring. After rotating a certain number of revolutions or angles, the servo motor automatically stops. The servo motor then disconnects from the ruler spring's rotating shaft via a downward axis. The turntable rotates, proceeding to the next process.

[0046] (6): (Right wheel + right spring pretensioning) assembly conveyor

[0047] The pre-tightened ruler wheel assembly and ruler spring rotating shaft are gripped together by the gripping unit. After being adjusted by the assembly angle adjustment assembly, they are transported along the ruler wheel assembly conveyor rail to the next station - lower ruler shell installation.

[0048] (7) Installation of the lower casing

[0049] The lower casing of A contains a ruler spring spindle.

[0050] The image recognition system on the robotic arm identifies the quantity of rulers on the conveyor belt. When there are not enough rulers, the lower ruler is stored and sent onto the conveyor belt. The robotic arm takes an image to identify the posture of the lower ruler, picks it up, adjusts its posture, and after inspection, sends it to the lower ruler positioning fixture.

[0051] The ruler spring rotating shaft on the gripping unit of the ruler wheel pretensioning assembly is aligned with the ruler spring core shaft on the lower ruler housing. Pressing down causes the ruler wheel pretensioning assembly to disengage from the ruler spring rotating shaft and be installed onto the ruler spring core shaft on the lower ruler housing.

[0052] B. Lower ruler housing positioning fixture: The lower ruler housing positioning fixture is equipped with a clamping device to tighten the head of the ruler spring and prevent the ruler spring from contracting on the pre-tightened components.

[0053] At this point, the lower scale housing assembly (including the scale wheel preload assembly) is complete. Now, we await the installation of the upper scale housing assembly.

[0054] (7) Installation of the upper scale housing assembly: (lifting strap + scale nozzle + scale brake)

[0055] A: Carry and install

[0056] The image recognition system identifies the number of carrying straps on the conveyor belt. When the number decreases, a signal is sent to the carrying strap storage unit, causing the number to increase via the conveyor belt. The image recognition system also identifies the posture of the carrying straps. After the robotic arm grasps and adjusts them, they are placed into a specific fixture on the turntable of the lower casing assembly.

[0057] B: Installation of the caliper gate assembly

[0058] The vibratory plate of the ruler brake vibrates, and after the ruler brake track is straightened, the ruler brakes are arranged in sequence on the track. The gripping unit picks up the ruler brake, raises it, and the synchronous belt moves forward to the designated position, rotates, lowers it, and installs it into the component installed in the previous process. At this time, the lifting strap and the ruler brake are installed in the lower ruler housing. Then the rotating plate rotates to the next station for the installation of the ruler nozzle.

[0059] C: Installation of the measuring nozzle

[0060] The vibrating disc vibrates, and the rulers, after being straightened by the ruler track, are arranged sequentially and reach the pre-grip position. A sensor at the pre-grip position detects the presence of the rulers. The gripping unit then grips the rulers according to system knowledge, and a synchronous belt propels them forward to insert the previously installed upper ruler housing assembly. At this point, the assembly installation is complete.

[0061] (8) Assembly of the upper and lower scale housing components

[0062] The upper measuring tape housing assembly, equipped with the carrying strap, brake, and nozzle, is gripped by the upper measuring tape housing gripping unit and pushed forward by the synchronous belt to assemble with the lower measuring tape housing assembly. At this point, the installation of the measuring tape housing assembly, the measuring wheel assembly, the carrying strap, brake, and nozzle is complete. In other words, the main components of the measuring tape are now installed.

[0063] (9) Installation of the casing screws

[0064] The assembled components, after the above steps, are rotated to the screw mounting position on the measuring tape. One or more screw machines can be mounted on the base. The screw machines travel along tracks to the designated positions, align with the screw holes on the measuring tape, and install the screws. The screw bits are replaceable to accommodate different measuring tape and measuring tape screw models. The screw machine includes an automatic screw feeding function.

[0065] After the screws are installed, rotate to the next station - the installation of the measuring tape.

[0066] (10) Installation of the measuring tape.

[0067] The measuring tapes are stacked one by one in the measuring tape groove. The suction cup picks up the top measuring tape and sends it to the flipping mechanism. The flipping mechanism flips 90 degrees to hang the measuring tape on the spring head and restores it to its original position. The spring head clamping mechanism opens and the measuring tape is retracted into the measuring tape.

[0068] As can be seen from the shape of the punched hole at the end of the measuring tape and the shape of the measuring spring at the end, the suction cup measuring tape is delivered to the measuring tape rotating mechanism. The measuring tape rotating mechanism aligns with the position, rises first, and after passing through half of the punched hole at the end of the measuring tape, it rotates 90-100 degrees clockwise to connect the measuring tape with the measuring spring. Then, the clamping mechanism of the measuring spring is released, and the measuring tape retracts into the measuring housing under the force of the measuring spring. The measuring tape installation is complete.

[0069] (11) Installation of belt buckle and locking of center pin

[0070] The belt buckle vibratory feeder detects the number of belt buckles in the feeder via a vibrating rod. If the number is insufficient, the belt buckle storage unit is triggered to supply buckles. Through vibration, the belt buckles are aligned on the track and arranged sequentially, with the foremost buckle positioned for pre-grabbing. The grabbing unit picks up the belt buckles, and the synchronous belt moves forward to the designated position. The buckles then descend and rotate into the center of the upper measuring tape housing. The screw machine tightens the center screw, and the measuring tape assembly is complete, ready for production.

[0071] The above describes the entire process of automatic installation of the measuring tape and the operation of each mechanism. In this invention, unless otherwise explicitly specified and limited, for example, the connection may be fixed, detachable, or integral; it may be mechanical or electrical; it may be direct or indirect through an intermediate medium; it may be the internal connection of two components or the interaction between two components. Unless otherwise explicitly limited, those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0072] The above are preferred embodiments of the present invention. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
