DETAILED DESCRIPTION

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0013] like Figure 1-6 As shown, the embodiment of the present invention includes: A torsion spring torsion assembly and adjustment device for a double-cover armrest box comprises a machine platform 1, an armrest box positioning base 2, a cylinder slide 3 on one side and cylinder slides 4 on two sides, a servo motor 5, a slide cylinder 6, an air claw 7, a rotary cylinder 8 and a swing arm 9. The machine platform 1 is provided with an armrest box positioning base 2, and the left and right sides of the armrest box positioning base 2 are provided with a cylinder slide 3 on one side and cylinder slides 4 on two sides, a servo motor 5 is mounted on the cylinder slide 3 on one side, a slide cylinder 6 is vertically installed at the front end of the servo motor 5, and an air claw 7 is horizontally mounted on the slide cylinder 6. A torsion spring torsion lock contour chuck 10 is installed at the front end of the air claw 7, a rotating cylinder 8 is mounted on the two side cylinder slides 4, a swing arm 9 is installed at the front end of the rotating cylinder 8, a pressure roller 11 is arranged on the swing arm 9, a first visual camera 12 is mounted on the upper side of the armrest box positioning base 2, and at least two second visual cameras 13 are centrally arranged below the armrest box positioning base 2; the servo motor 5 is used to realize the torsion angle adjustment of the torsion spring torsion lock 100, and the slide cylinder 6 is used to realize the floating clutch of the torsion spring torsion lock 100.

[0014] Among them, a number of positioning pins 14 are arranged on the edge of the armrest box positioning base 2, a horizontal cylinder 15 is mounted on the outer side of the armrest box positioning base 2, a wedge-shaped pressure block is installed at the front end of the horizontal cylinder 15, and the wedge-shaped pressure block is matched with the positioning pin 14. The wedge-shaped pressure block is used to suppress the longitudinal displacement of the product, and the positioning pin 14 is used to suppress the lateral displacement of the product.

[0015] Furthermore, a Z-axis lifting cylinder 16 is mounted on the outer side of the armrest box positioning base 2, and a torsion spring pre-tensioning bracket 17 is installed at the front end of the Z-axis lifting cylinder 16. A torsion spring pre-tensioning bracket 17 is provided with a torsion spring hook positioning groove. The torsion spring pre-tensioning bracket 17 is an angle steel with a Z-shaped structure, and the torsion spring pre-tensioning bracket 17 is used to realize the clamping assembly of the torsion spring and the torsion spring torsion lock 100.

[0016] Furthermore, a lower-facing photoelectric sensor 2a obliquely upward is provided in the armrest box positioning base 2, and upper-facing photoelectric sensors 2b obliquely downward are provided on both sides of the first visual camera 12. The lower-facing photoelectric sensors 2a and the upper-facing photoelectric sensors 2b are opposite to each other, and two lower-facing photoelectric sensors 2a and two upper-facing photoelectric sensors 2b are provided and are respectively used for synchronous detection of the opening moment of the double cover 200.

[0017] Furthermore, two servo motors 5 and two rotary cylinders 8 are provided.

[0018] Furthermore, a through opening matching the second visual camera 13 is opened on the machine platform 1 , and a transparent cover is installed at the through opening, and the transparent cover blocks the front end of the second visual camera 13 .

[0019] Specifically, the basic situation of the armrest box product is as follows: an integrally formed shaft seat 1001 is provided on the base of the armrest box. The shaft seat 1001 is hollow and plugs in a rotating shaft 1002. The rotating shaft 1002 is connected to the box cover 1003 to realize opening and closing. The shaft seat 1001 is columnar and coaxially sleeved with a torsion spring 1004. One end of the torsion spring 1004 is connected to the box cover 1003, and the other end uses a torsion spring torsion lock 100 to control the torsion angle. The torsion spring torsion lock 100 is a multi-toothed part similar to a pin shape and has an axial hole 1005. The torsion spring torsion lock 100 is coaxially installed on the shaft seat 1001 through the axial hole 1005. The shaft seat 1001 is surrounded by a wall 1006. The torsion spring torsion lock 100 is inserted into the notch of the wall 1006. The two can be flexibly matched together to prevent slipping. A step groove 1007 is provided on the torsion spring twist lock 100 , and the outer end hook of the torsion spring 1004 is hooked in the step groove 1007 .

[0020] Therefore, the elastic force of the torsion spring 1004 can be adjusted by rotating the torsion spring twist lock 100 around the shaft seat 1001. The greater the elastic force of the torsion spring 1004, the faster the armrest box cover 200 opens. In order to keep the opening speeds of the two symmetrical armrest box covers 200 consistent and achieve the effect of synchronous and speed opening, the multi-stage latch 1010 (this product is set as a three-stage latch) on the torsion spring twist lock 100 is used. In order to achieve fine-tuning of the angle of the hook at the outer end of the torsion spring 1004 by the torsion spring twist lock 100, the multi-stage slot 1011 on the inner wall of the wall 1006 is required, which can be achieved by the mutual engagement of the multi-stage latch 1010 and the multi-stage slot 1011.

[0021] So far, although the positioning of the hook angle of the torsion spring 1004 has been achieved, there is still a lack of corresponding fine-tuning means. In order to solve this problem, it is necessary to further add a structure to the torsion spring torsion lock 100 to realize the clutch of the multi-stage slot 1011 and the multi-stage latch 1010, that is, the aforementioned shaft hole 1005 is designed as a wire hole 1005, so that the axial position of the entire torsion spring torsion lock 100 can be switched from one end of the wire hole 1005 to the other end of the wire hole 1005. In order to realize such a floating switching function, the slide cylinder 6 of this device must be used. After completing the floating switching action, the servo shaft 5 is also required to adjust the rotation angle of the torsion spring torsion lock 100, that is, to adjust the bite relationship between the multi-stage latch 1010 and the multi-stage slot 1011.

[0022] Based on the above technical principles, the calibration device of the present application is designed. The device can not only detect whether there is light leakage in the gap of the armrest box, but also be used to detect and adjust whether the opening process of the armrest box cover is synchronous and at the same speed.

[0023] Among them, the detection of light leakage problems is realized by two cameras below the center seam of the armrest box, the detection of lid opening synchronization problems is performed by a third camera placed obliquely on the armrest box, and the lid opening action is realized by the downward pressure cylinder 2000.

[0024] In addition, the present device also involves the automatic assembly of the torsion spring torsion lock 100. The torsion spring torsion lock 100 is clamped by the air claw 7 and then pushed into the shaft seat 1001 by the cylinder slide 3. The detection of the opening and closing speed of the armrest box cover is visually determined by the camera 12. If the two covers cannot be opened synchronously and at the same speed, it is necessary to switch the matching relationship between the multi-stage latch 1010 and the multi-stage slot 1011, that is, to switch the bite position. In order to trigger the opening action during detection, the present device is also designed with a downward pressure cylinder 2000 facing the physical switch of the armrest box cover, which can automatically press the opening button to open the armrest box cover 200. The present device is also designed with a cover closing mechanism, and the cover closing action is achieved by means of a roller 11 driven by the swing arm 9, and the roller 11 is located on the side of the armrest box cover 200. If the opening speed of the armrest box cover is not synchronized after the test, the roller 11 will flip the armrest box cover and press it down to reset through the swing arm 9, and then fine-tune the angle of the torsion spring torsion lock 100, and re-engage the multi-stage latch 1010 with the multi-stage slot 1011, and then test again. The physical unlocking switch equipped with the armrest box can be repeatedly pressed by the downward cylinder 2000 to repeat the adjustment process. After pressing the physical unlocking switch, the armrest box cover can be automatically opened under the elastic force of the torsion springs at both ends.

[0025] In addition, the torsion spring is pre-installed on the shaft seat by the operator, and the torsion spring toggle lock is pre-delivered to the air gripper 7 by the operator. The machine 1 of this equipment is also equipped with a labeling machine, which can facilitate the operator to label qualified or unqualified products. In addition, it is also equipped with a material box for the torsion spring toggle lock and a material box for the torsion spring. The front of the machine 1 is also equipped with a pre-installed control switch for the torsion spring toggle lock, which can adjust the opening and closing of the air gripper 7 separately.

[0026] In summary, the present invention provides a torsion spring torsion assembly and adjustment device for a double-cover armrest box, which realizes quantitative fine-tuning of the torsion spring damping through the linkage of a servo motor, a slide cylinder and an air claw, thereby quickly realizing the synchronous calibration of the double-cover armrest box, and at the same time utilizes the linkage of a rotating cylinder and a swing arm to realize the double-cover resetting during the calibration process, which greatly improves the adjustment efficiency of the armrest box and realizes the precise unification of the double-cover damping.
