[0048] The base 207 is installed on the ground. The adjustment module 204 itself is composed of a lead screw, a linear guide rail 214 and a linear base 207, and is driven by a servo motor 2052. Three sets of adjustment modules 204 are installed on the base 207 at equal intervals.

The third set of joints adjusts the bottom of the lifting slide and its two sliders 211, which are respectively screwed with the lead screw guide rail of the third adjustment module 204 and the linear guide rails 214 of the first and second adjustment modules 204. The locking and positioning release mechanism 202 is connected to the rear end of the upper plate of the joint adjustment lifting slide 203, and the pressure plate 2021 at the end is used as the force application point through air pressure drive to release the locking and positioning of the device. The tooling slide moving connection mechanism 206 is connected to the front end of the upper plate of the joint adjustment lifting slide 203, that is, the opposite side of the locking and positioning release mechanism 202. The clamping claw 2061 of the mechanism can be clamped and released under the drive of the cylinder. The tooling transmission mechanism 205 is installed on the two side vertical plates of the base 207 to provide driving force for the automatic positioning adjustment unit.

[0049] In a preferred embodiment of the present invention, the locking and positioning release mechanism 202 includes a pressing plate 2021 and an unlocking cylinder 2022 .

[0050] The unlocking cylinder 2022 is installed on the upper plate surface of the joint adjustment lifting slide 203, and the pressure plate 2021 is screwed to the end of the push rod of the unlocking cylinder 2022.

[0051] In a preferred embodiment of the present invention, the tooling slide movable connection mechanism 206 includes a clamp 2061 and a dual-axis cylinder 2062 .

[0052] The base 207 of the dual-axis cylinder 2062 is installed on the upper plate surface of the joint adjustment lifting slide 203 and is located on the opposite side of the locking positioning release mechanism 202. The clamping claw 2061 is screwed to the ends of the push rods at both ends of the dual-axis cylinder 2062.

[0053] In a preferred embodiment of the present invention, the tooling transmission mechanism 205 includes a fixing seat 2051 , a servo motor 2052 , a driving wheel 2053 , a conveyor belt 2054 , a tensioning wheel 2055 , and a reversing wheel 2056 .

[0054] The fixing seat 2051 is installed on the side plate of the base 207, the output shaft of the servo motor 2052 passes through the shaft hole of the fixing seat 2051, and the end is connected to the driving wheel 2053 through a flat key, two tensioning wheels 2055 and a reversing wheel 2056 are screwed on the fixing seat 2051, and the conveyor belt 2054 is wound around the two reversing wheels 2056, the tensioning wheel 2055 and the driving wheel 2053. The mechanism drives the driving wheel 2053 through the servo motor 2052, thereby making the conveyor belt 2054 run.

[0055] In a preferred embodiment of the present invention, the automatic positioning and adjustment unit includes a moving platform 208, a joint slide 209, a locking positioning device 210, a slider 211, a lever of the joint slide 209, a hinge placement slot 213, and a linear guide rail 214.

[0056] Three linear guides 214 are installed at equal intervals on the moving platform 208. Two sliders 211 are provided under each bottom plate of the joint slide 209, and the sliders 211 cooperate with the linear guides 214. Each joint slide 209 lever is installed below the upper plate end of the joint slide 209. The joint slide 209 lever is located in the clamp 2061 of the tooling slide moving connection mechanism 206. The movement control of the joint slide 209 is realized by grasping the lever by the clamp 2061. The locking and positioning device 210 is installed below the rear end of the upper plate of the joint slide 209, and its positioning block is located directly above the locking and positioning release mechanism 202. Under the action of the compression spring, the upper positioning plate and the positioning block of the locking and positioning device 210 are pressed against the upper plate of the joint slide 209 and the upper surface of the moving platform 208, respectively. A hinge placement groove 213 with high flatness (flatness is 0.05 / 100mm) is installed above the upper plate of the joint slide 209. According to actual working conditions, multiple groups of high flatness hinge placement grooves 213 can be set.

[0057] Before assembling the linear rod product, the operator selects the linear rod model on the operation screen, clicks the automatic positioning adjustment unit out of the warehouse button, and the three-dimensional warehouse 1 starts, and the idle automatic positioning adjustment unit is transferred to the elevator 103 via the drive roller 104. Under the control of the drive system 106, the transmission system 105 drives the elevator 103 to transfer the automatic positioning adjustment unit to the tooling transmission mechanism 205 in the positioning drive device. Under the synchronous drive of the drive roller 104 and the tooling transmission mechanism 205 in the elevator 103, the automatic positioning adjustment unit is transferred to the positioning drive device.

[0058] The operator places the hinge joint into the hinge placement groove 213, and uses the tools in the tool box 3 to grind the end face and inner hole of the product joint. After the ground surface meets the assembly requirements, the linear rod is manually cleaned and glued, and finally the processed linear rod is put into assembly.

[0059] After determining the model of the linear rod to be assembled, the system can automatically retrieve the linear rod size and other related information, press the positioning button, and the automatic positioning adjustment unit will adjust the position of the three groups of joint slides 209. The joint adjustment lifting slide 203 is driven by the motor to lift its upper plate upward, driving the tooling slide mobile connection mechanism 206 and the locking positioning release mechanism 202 on its surface to move in the vertical direction. These two mechanisms quickly find and reach the position of the joint slide lever 212 and the positioning block position of the locking positioning device 210 through sensors. The clamp on the tooling slide mobile connection mechanism 206 is driven by the cylinder to clamp the joint slide lever 212, thereby realizing the control of the joint slide. The pressure plate 2021 on the locking and positioning release mechanism 202 contacts the positioning plate surface of the locking and positioning device 210 under the drive of the unlocking cylinder 2022 and applies an upward thrust, so that the spring of the locking and positioning device 210 shortens the extension distance due to pressure, the positioning block separates from the moving table 208, and the joint slide 209 is in an unlocked state.

[0060] The distance between the three groups of joint slides 209 is adjusted by the linear rod model input before assembly. The system controls the three groups of servo motors of the adjustment module 204 to drive each group of screw rods to move the joint adjustment lifting slide 203 along the axis of the screw rod. Under the control of the tooling slide moving connection mechanism 206 and the locking and positioning release mechanism 202, the joint slide 209 moves on the linear guide rail 214 to adjust the distance between the three groups of joint slides 209. Through the high-precision magnetic sensor (accuracy of ±0.02mm) under the joint slide 209, the position of each group of joint slides 209 can be read out and the system can be accurately adjusted. When the distance between the two groups of joint slides 209 is the specified value of the linear rod model, the pressure plate of the locking and positioning release mechanism 202 is lowered, so that the positioning block of the locking and positioning device 210 locks the joint slide 209 on the moving platform 208 under the action of the spring, and keeps the distance between the three groups of joint slides 209 unchanged. At the same time, the clamping claw of the tooling slide mobile connection mechanism 206 is loosened under the cylinder drive, and the control of the joint slide lever 212 is lost. The indicator light is green, waiting for the operator to load the material and latch.

[0061] After the bolt is completed, the assembly of a set of linear rods is completed. Click the completion button, and the joint adjustment lifting slide 203 is driven by the motor to lower the lifting slide, driving the tooling slide moving connection mechanism 206 and the locking positioning release mechanism 202 on its surface to synchronously lower, and the overall height is lower than the lower surface of the moving platform 208 in the automatic positioning adjustment unit. The tooling conveying mechanism 205 on both sides of the positioning drive device is started, so that the automatic positioning adjustment unit moves to the driving roller 14 in the elevator 13. Under the synchronous drive of the driving roller 14 and the tooling conveying mechanism 205, the assembled linear rod product is put into the elevator 13 together with the automatic positioning adjustment unit, and then the product and the automatic positioning adjustment unit are stored in the three-dimensional warehouse 1 under the action of the driving system 16, the transmission system 15 and the driving roller 14. After the warehousing is completed, the three-dimensional warehouse 1 continues to take out the idle automatic positioning adjustment unit, according to the above operation, until all linear rods are assembled and positioned.

[0062] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
