[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. 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.

[0034] Embodiment 1

[0035] See also Figures 1 to 3 As shown, a mobile phone cover glass listening hole slot identification and feeding device in an embodiment of the present invention includes a body 1, which is the basic frame of the device and provides an installation and support basis for other components in the device, and also includes:

[0036] The double-sided conveyor belt 2 is arranged on the inner side of the machine body 1, and the belt surface of the double-sided conveyor belt 2 has a baffle. Specifically, the double-sided conveyor belt 2 adopts the industrial conveyor belt structure commonly used in the prior art, and the width of the belt is selected according to the size of the subsequent deviation correction material tray 6 and the feeding requirements. The baffle on the belt surface is used to limit the deviation correction material tray 6 to prevent it from sliding.

[0037] Planar robot 3, the plane robot 3 is fixed on one side of the rear section of the machine body 1. In this embodiment, the plane robot 3 adopts a SCARA plane robot to ensure high precision and high speed in the process of taking and placing the film. The plane robot 3 is fixed to the corresponding position of the machine body 1 by bolts, and its installation height is adjusted according to the actual working plane to ensure that its mechanical arm can conveniently perform the picking and placing operation on the deviation correction tray 6.

[0038] The mounting frame 4 is fixed to the other side of the rear section of the machine body 1. The upper end of the mounting frame 4 is fixed with a wide-angle automatic image measuring instrument 5 electrically connected to the plane robot 3. The lower end of the mounting frame 4 is firmly fixed to the machine body 1 by welding or bolting. The wide-angle automatic image measuring instrument 5 is electrically connected to the plane robot 3 through a data cable and is located in the upper middle part of the machine body 1 after installation. The field of view of the wide-angle automatic image measuring instrument 5 is adjusted according to the size of the mobile phone cover glass and the area to be covered, ensuring that its measurement area can cover the deviation correction material tray 6 without interfering with the movement of the plane robot 3.

[0039] The deflection correction tray 6 is arranged above the double-sided conveyor belt 2 and is used for loading the mobile phone cover glass.

[0040] When in use, the mobile phone cover glass is loaded in the deviation correction material tray 6, and is conveyed by the double-sided conveyor belt 2. It stops after completely entering the measurement area of ​​the wide-angle automatic image measuring instrument 5. The wide-angle automatic image measuring instrument 5 analyzes and judges the size of the cover plate, identifies the position of the listening hole slot, and transmits the data to the plane robot 3 when a reverse direction occurs, and the position of the mobile phone cover glass is adjusted by the plane robot 3. For example, if the position deviation angle of the cover glass is 180 degrees, the plane robot 3 will rotate the mobile phone cover glass 180 degrees to adjust the position of the listening hole slot to the correct direction.

[0041] After adjustment by the planar robot 3, the position of the mobile phone cover glass is corrected to meet the requirements of subsequent processing procedures such as automatic silk screen printing, preventing the automatic silk screen printer from printing the direction of the listening hole as the direction of the microphone, causing the error of printing in the opposite direction.

[0042] Among them, the grasping tool of the planar robot 3 can adopt a vacuum suction cup, and by adjusting the suction force and distribution of the suction cup, it can ensure the firm grasping and stable operation of the mobile phone cover glass during the position adjustment process; and the method of detecting whether the correction material tray 6 is in place can adopt a photoelectric sensor (not shown in the figure), which is a commonly used technical means in this field and will not be repeated here.

[0043] Embodiment 2

[0044] The mobile phone cover glass is placed on the upper plate 62 of the deviation correction tray 6. Due to manual placement or other factors such as vibration, the initial position of the mobile phone cover glass may be skewed or uneven, which may bring many adverse effects.

[0045] First, the image processing algorithm of the wide-angle automatic image measuring instrument 5 is usually designed based on standard image patterns and object shapes. Uneven mobile phone cover glass will produce irregular images, which will cause the data processed by the algorithm to deviate from the normal range, reducing the reliability of recognition and processing speed;

[0046] Secondly, it will also affect the accuracy of the planar robot 3 grasping, and increase the complexity and time consumption of the adjustment action. For example, when rotating the mobile phone cover glass 180 degrees to correct the direction of the listening hole slot, if there is a deviation in the initial position, the planar robot 3 needs to move it to an accurate reference position first, and then perform the rotation operation, instead of rotating it directly at the original position, which will increase multiple operation steps and corresponding time costs. Therefore, this embodiment is provided.

[0047] See also Figures 2 to 7 As shown, on the basis of the first embodiment, the deviation correction material tray 6 includes a bottom plate 61 and an upper plate 62, the upper plate 62 is fixedly connected to the upper side of the bottom plate 61, and a plurality of deviation correction mechanisms 65 are arranged in an internal array of the bottom plate 61;

[0048] Among them, mesh holes 63 are arranged at the positions of the plurality of deviation correction mechanisms 65 on the surface of the bottom plate 61. The mesh holes 63 can reduce the weight of the upper plate 62. In addition, when the mobile phone cover glass is placed on the upper plate 62, the existence of the mesh holes 63 provides a uniform channel for the gas to be discharged. Unlike the plane structure, when the mobile phone cover glass is placed on the plane structure, the air at the bottom will be quickly discharged from the edge. This uneven exhaust process may affect the placement position of the mobile phone cover glass, causing it to be offset or uneven. The existence of the mesh holes 63 allows the bottom gas to be discharged evenly, avoiding the position deviation caused by uneven gas discharge, thereby improving the position accuracy of the mobile phone cover glass after placement.

[0049] The deviation correction mechanism 65 includes a pulley 1 651 and four groups of reciprocating components 657. A deviation correction rod 658 is fixedly connected to the inner side of the upper end of the reciprocating component 657. The top of the deviation correction rod 658 is hemispherical and made of wear-resistant and smooth material to avoid scratching the mobile phone cover glass. The upper end of the deviation correction rod 658 extends out of the through slot 64 provided on the bottom plate 61. The size design of the through slot 64 ensures that the deviation correction rod 658 can move freely without getting stuck. The pulley 1 651 is arranged in the middle of the four groups of reciprocating components 657 and a gear 652 is fixedly connected to the lower end. The lower part of the reciprocating component 657 is connected with a pulley 3 655 and a pulley 2 654 in sequence. The pulley 1 651 and the pulley 2 654 are connected with a synchronous belt 1 653. A synchronous belt 2 656 is wound around the four pulleys 3 655. The pulley 1 651 and multiple pulleys 2 654 are all rotatably connected to the bottom plate 61.

[0050] Racks 7 are fixedly connected to the inner sides of the two frames of the double-sided conveyor belt 2. The gear 652 extends out of the lower end surface of the bottom plate 61. When the deviation-correcting material tray 6 passes over the rack 7, the gear 652 can mesh with the rack 7.

[0051] When in use, the double-sided conveyor belt 2 is started to drive the correction material tray 6 to move along the conveyor belt. During the movement, when the correction material tray 6 passes over the rack 7 of the double-sided conveyor belt 2, the gear 652 meshes with the rack 7 to convert the linear motion of the double-sided conveyor belt 2 into the power of the correction mechanism 65. Specifically, the rotation of the gear 652 drives the pulley 1 651 to rotate, and through the transmission of the synchronous belt 1 653, the pulley 2 654 rotates, thereby driving the 655 connected thereto to rotate. Since multiple pulleys 3 655 are connected by synchronous belts 656, each pulley 3 655 rotates synchronously, driving the reciprocating assembly 657 to move, so that the correction rod 658 reciprocates and contacts the mobile phone cover glass. By pushing on four sides, the mobile phone cover glass is corrected, which can cope with the deflection of various mobile phone cover glasses and ensure the position accuracy of the mobile phone cover glass. For example, if the mobile phone cover glass deflects to the left, the correction rod 658 on the left side will push it to the right, and finally the mobile phone cover glass will be neatly placed on the correction tray 6.

[0052] It should be noted that the four deviation correction rods 658 are distributed in a diamond shape, corresponding to the two long sides and the short sides of the mobile phone cover glass respectively.

[0053] In this embodiment, the length of the rack 7 is twice the circumference of the gear 652 , ensuring that the gear 652 can complete a sufficient rotation stroke when passing through the rack 7 .

[0054] Among them, the reciprocating component 657 includes a moving ring 6571 and a half gear 6574. Both sides of the moving ring 6571 are slidably sleeved with a slide groove 6573. The slide groove 6573 is fixedly connected to the upper plate 62. Tooth grooves 6572 are provided on both sides of the inner end of the moving ring 6571. The half gear 6574 is fixed to the pulley three 655 and meshed with the tooth groove 6572. The moving ring 6571 can achieve smooth reciprocating sliding in the slide groove 6573. When the pulley three 655 rotates, the half gear 6574 will rotate with it. The outer quarter area of ​​the half gear 6574 has a tooth head. After one circle of rotation, it will mesh with the tooth grooves 6572 on both sides of the moving ring 6571, thereby driving the moving ring 6571 to do reciprocating linear motion in the horizontal direction, thereby driving the correction rod 658 to correct the deviation of the mobile phone cover glass. Since the length of the rack 7 is twice the circumference of the gear 652, the gear 652 has sufficient rotation travel, so that the correction rod 658 can perform multiple reciprocating movements, thereby ensuring the accurate position of the mobile phone cover glass.

[0055] It should be noted that before the correction tray 6 is fed, each correction rod 658 needs to be in the expanded position, that is, in the outward expanded state, so as to leave space for the mobile phone cover glass to be placed in. In addition, after passing through the rack 7 area, since the length of the rack 7 is twice the circumference of the gear 652, the specifications of each pulley are the same, the half gear 6574 will rotate two circles, that is, the reciprocating assembly 657 will move twice, and the correction rod 658 will reset to the initial expanded state after the action, thereby preventing the cover glass from contacting and rubbing with the correction rod 658 when the subsequent planar robot 3 takes the film.

[0056] In summary, please refer to Figure 8 As shown, the overall workflow is as follows:

[0057] First, place the mobile phone cover glass on the upper plate 62 of the deflection correction material tray 6, then start the double-sided conveyor belt 2. When the deflection correction material tray 6 passes over the rack 7 on the inner side of the two frames of the double-sided conveyor belt 2, the deflection correction mechanism 65 in the deflection correction material tray 6 starts to work to correct the mobile phone cover glass, ensuring that the mobile phone cover glass is neatly placed, which provides convenience for subsequent operations. When the deflection correction material tray 6 carrying the mobile phone cover glass completely enters the measuring area of ​​the wide-angle automatic image measuring instrument 5, the double-sided conveyor belt 2 stops conveying. The wide-angle automatic image measuring instrument 5 identifies the position of the listening hole slot of the mobile phone cover glass, detects whether the position of the listening hole slot is correct, and transmits the data information to the plane robot 3. The plane robot 3 performs corresponding adjustment operations on the mobile phone cover glass according to the received data information:

[0058] For the positive mobile phone cover glass, the flat robot does not move;

[0059] For the reversed mobile phone cover glass, the flat robot takes the piece, rotates the mobile phone cover glass 180 degrees, adjusts it to the positive direction and puts it back.

[0060] After all are put back, the tray is sent out and enters the next process.

[0061] The above is a detailed description of an embodiment of the present invention, but the content is only a preferred embodiment of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
