Description

Technical Field

[0001] The utility model relates to the field of automation, and particularly to an automatic deviation rectification and positioning system for product installation. Background Art

[0002] For 3C digital products that need to assemble parts, the assembly and installation detection process is as described in the patent number "CN118404181A". A turntable platform is arranged in the middle of the main machine table to carry parts. A feeding transfer manipulator, an assembly module, a testing module, a marking module, and a discharging module are sequentially distributed in the circumferential direction of the working turntable; after the parts of the product are adsorbed and fed by the manipulator and assembled, they are placed on the working turntable and conveyed to the next station for testing. Since the current devices for testing products are all automated testing devices, the prerequisite for testing is that the position of the product needs to correspond to the position of the testing device. However, the position of the product placed on the working turntable after being assembled by the manipulator often has a certain position deviation from the testing position of the testing device. When the product rotates to the testing station with the working turntable, it cannot be guaranteed to exactly correspond to the position of the testing device; to avoid this situation, it is necessary to manually correct the position of the product before the testing work, which takes a long time for position adjustment and has extremely low manual adjustment efficiency. Therefore, it is urgent to solve. Summary of the Utility Model

[0003] In order to avoid and overcome the technical problems existing in the prior art, the utility model provides an automatic deviation rectification and positioning system for product installation. The utility model can realize the automatic deviation rectification and positioning of the product position, which is convenient for subsequent automated testing of the product.

[0004] To achieve the above object, the utility model provides the following technical solutions:

[0005] An automatic deviation rectification and positioning system for product installation includes a working turntable driven by a power source to rotate. Positioning platforms are evenly arranged along the circumference on the working turntable. A deviation rectification area for placing the product to be deviation rectified is arranged on the positioning platform; in each deviation rectification area, a first positioning block and a second positioning block are arranged perpendicular to each other. The main push deviation rectification mechanism generates a linear pushing action on the product to be deviation rectified along the direction perpendicular to the first positioning block, and the side push deviation rectification mechanism generates a linear pushing action on the product to be deviation rectified along the direction perpendicular to the second positioning block. After the first positioning block and the second positioning block cooperate, they form a right-angle abutting positioning for the product to be deviation rectified. A pressing block for generating a pressing action on the product to be deviation rectified in the vertical direction is also arranged in the deviation rectification area; a deviation rectification probe for monitoring the deviation rectification position of the product to be deviation rectified is arranged on the working turntable.

[0006] As a further solution of the utility model: the main push and deviation correction mechanism includes a main push screw rod, and the main push screw rod drives the main push screw rod slider to move linearly through the cooperation of the screw rod slider; the side push platform is fixed at the axis of the working turntable and is rotationally matched with the working turntable. The main push and deviation correction mechanism is arranged outside the working turntable. Along the radial direction of the working turntable, the side push and deviation correction mechanism and the main push and deviation correction mechanism are distributed on both sides of the positioning table, and the side push screw rod and the main push screw rod are both arranged along the radial direction of the working turntable.

[0007] As a further solution of the utility model: the side push and deviation correction mechanism includes a side push screw rod installed on the side push platform, and the side push screw rod drives the side push screw rod slider to move linearly through the cooperation of the screw rod slider; a side push slider that forms a horizontal sliding fit with the side push screw rod slider is installed in the side push screw rod slider, and the sliding direction of the side push slider forms an angle with the movement direction of the side push screw rod slider, and the angle is not a right angle; a side push lever for pushing the product is fixed on the side push slider along the advancing direction of the side push screw rod slider, and a limit head is installed on the side push platform. When the side push slider advances with the side push screw rod slider until it abuts against the limit head, the limit head generates a reverse thrust on the side push slider so that the side push slider and the side push screw rod slider slide relatively; along the sliding direction of the side push screw rod slider, the distance between the side push slider and the limit head is smaller than the distance between the side push screw rod slider and the limit head.

[0008] As a further solution of the utility model: the side push slider horizontally penetrates through the side push screw rod slider and then forms a sliding fit with the side push screw rod slider. A guide groove is formed along the length direction on the side push slider, and a guide post corresponding to the groove width of the guide groove is arranged vertically on the side push screw rod slider, and the end of the guide post forms a sliding fit with the cavity of the guide groove.

[0009] As a further solution of the utility model: a return spring is arranged along the length direction of the guide groove in the guide groove, one end of the return spring abuts against the groove wall of the guide groove, and the other end of the return spring abuts against the column body of the guide post.

[0010] As a further solution of the utility model: the limit head is a limit bearing, the axis of the limit bearing is arranged vertically, and the side push slider forms a rolling friction fit after abutting against the limit bearing.

[0011] As a further solution of the utility model: the side push lever is an elastic lever that can generate a bending action.

[0012] As a further solution of the utility model: when the side push slider does not abut against the limit head, along the radial direction of the working turntable, the side push lever avoids the rotation path position of the positioning table; when the side push slider abuts against the limit head, along the radial direction of the working turntable, the side push lever is located on the side of the product to be corrected and is arranged opposite to the second positioning block; when the side push slider slides in cooperation with the side push screw rod slider, it drives the side push lever to move towards the second positioning block.

[0013] As a further solution of the utility model: the positioning table is fixedly pressed on the working turntable by a pressing plate, forming a detachable fit with the working turntable.

[0014] As a further solution of the utility model: at least two groups of parallel main push elastic ejector pins are arranged on the main push screw slider of the main push deviation correction mechanism, and each main push elastic ejector pin applies an elastic pressing action to the product to be deviation corrected; the pressing block is an elastic pressing block driven by a cylinder to move up and down.

[0015] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0016] 1. The utility model arranges the main push deviation correction mechanism and the side push deviation correction mechanism radially on the working turntable, so that on two pushing directions perpendicular to each other, the adjacent two sides of the product to be deviation corrected are pushed to abut against the two positioning blocks in the deviation correction area. After the product to be deviation corrected is formed into a right-angle abutting positioning by the two groups of positioning blocks, the product to be deviation corrected is pressed by the pressing block, and then the main push deviation correction mechanism and the side push deviation correction mechanism are withdrawn and reset. The product to be deviation corrected can be conveyed to the next test station under the set positioning surface, thus completing the automated test work.

[0017] 2. The screw rod structures of the main push deviation correction mechanism and the side push deviation correction mechanism of the utility model are both arranged radially along the working turntable; when the side push slider and the side push lever move linearly along with the side push screw slider and the side push slider is not in contact, there is still a certain distance between the side push lever and the positioning table along the radial direction of the working turntable. The side push lever moves linearly along the radial direction of the working turntable to approach the side of the product to be deviation corrected; when the side push slider abuts against the limit head, at this time the side push lever just moves to the side of the corresponding product to be deviation corrected, thus being arranged opposite to the second positioning block; after the side push slider abuts against the limit head and the side push screw slider continues to move forward, relative sliding occurs between the side push slider and the side push screw slider. During the sliding, since the side push slider cannot continue to move forward, it rolls with the limit head. The side push lever at the end of the side push slider generates a horizontal displacement along the tangential direction of the working turntable, thus moving towards the second positioning block direction and pressing the other end of the product to be deviation corrected against the second positioning block. The forward and then lateral movement of the side push lever can be realized through the linear movement of the side push screw; there is no need to install a linear driving source in the tangential direction of the working turntable. Through the two groups of screw rod structures arranged radially along the working turntable, a right-angle positioning of the product to be deviation corrected can be formed, making full use of the compact installation space of the working turntable.

[0018] 3. Through the sliding fit of the guiding column and the guiding groove, the utility model can realize the guiding of the sliding of the side-pushing slider. The arrangement of the reset spring in the guiding groove enables the reset spring to be compressed when there is relative sliding between the side-pushing screw slider and the side-pushing slider. After the side-pushing screw slider is reset, under the action of the elastic force of the reset spring, the side-pushing slider can automatically slide back to its original position. The limiting head is designed as a bearing structure, which can form a rolling friction fit between the side-pushing slider and the limiting head during sliding, with less friction. The bendable design of the side-pushing lever can apply an elastic pressing force to the product to be corrected, avoiding rigid pressing damage to the product surface during pressing.

[0019] 4. With the design of multiple groups of main-pushing elastic ejector pins in the main-pushing deviation-correcting mechanism of the utility model, a multi-point pressing force can be applied to the product to be corrected, adapting to products with irregular shapes and enabling the side of the product to be corrected to be fully abutted against the first positioning block.

[0033] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0034] Please refer to Figures 1 to 5 , in the embodiments of the present invention, an automatic rectification and positioning system for product installation includes a working turntable 1 driven by a power source to rotate. The side push platform 35 of the side push rectification mechanism 3 is fixed at the center of the working turntable 1 and is in rotational cooperation with the working turntable 1. When the working turntable 1 rotates, the side push platform 35 remains stationary. Positioning platforms 11 are uniformly arranged along the circumference of the working turntable 1. The positioning platforms 11 are pressed against the working turntable 1 by pressing plates 12, so as to form a detachable fit with the working turntable 1. Different sizes of positioning platforms 11 can be replaced according to different products. A rectification probe for monitoring the rectification position of the product 4 to be rectified is arranged on the working turntable 1. The position of the product is observed in real time through the probe to ensure the accuracy of the rectification position.

[0035] The main push rectification mechanism 2 is arranged outside the working turntable 1. When the working turntable 1 rotates, both the main push rectification mechanism 2 and the side push rectification mechanism 3 avoid the rotation path positions of the positioning platforms 11. When one group of positioning platforms 11 rotates between the main push rectification mechanism 2 and the side push rectification mechanism 3, the product 4 to be rectified in this positioning platform 11 starts the rectification operation.

[0036] Along the radial direction of the working turntable 1, the main push rectification mechanism 2 and the side push rectification mechanism 3 are located on the same straight line. Rectification areas 111 for placing the product 4 to be rectified are uniformly arranged along the length direction of the positioning platforms 11. First positioning blocks 112 and second positioning blocks 113 arranged perpendicular to each other are arranged in the rectification areas 111. After the product 4 to be rectified is adsorbed by the manipulator and placed in the rectification area 111, the main push rectification mechanism 2 and the side push rectification mechanism 3 push the product 4 to be rectified. The two sides of the product 4 to be rectified are respectively abutted against the first positioning block 112 and the second positioning block 113, so as to complete the positioning.

[0037] A pressing block 114 for pressing the product 4 to be rectified in the vertical direction is also arranged in the rectification area 111. The pressing block 114 is driven by a cylinder, and the pressing block 114 is an elastic pressing block. The rectified product is pressed by the elastic pressing force in the vertical direction. The number of pressing blocks 114 is preferably multiple groups, and the product 4 to be rectified is pressed at multiple points.

[0038] The main push deviation rectifying mechanism 2 includes main push lead screws 21 arranged radially along the working turntable 1, and the number of main push lead screws 21 corresponds to the number of deviation rectifying areas 111. Each main push lead screw 21 drives the corresponding main push lead screw slider 22 to move linearly through a lead screw-slider fit. Preferably, at least two groups of parallel main push elastic ejector pins 23 are arranged inside each main push lead screw slider 22. The main push elastic ejector pins 23 are arranged parallel to the main push lead screws 21 and are arranged opposite to the positions of the first positioning blocks 112. After the main push elastic ejector pins 23 move linearly with the main push lead screw sliders 22 until they abut against the product 4 to be deviation rectified, the main push elastic ejector pins 23 elastically expand and contract to apply an elastic pressing force to the product 4 to be deviation rectified. Through the cooperation of multiple groups of main push elastic ejector pins 23, a multi-point pressing force can be applied to the product 4 to be deviation rectified, adapting to products with irregular shapes, so that the side of the product 4 to be deviation rectified fully abuts against the first positioning blocks 112.

[0039] On the side push platform 35 of the side push deviation rectifying mechanism 3, side push lead screws 34 corresponding to the number of deviation rectifying areas 111 are fixed. Each side push lead screw 34 drives the corresponding side push lead screw slider 33 to move linearly through a lead screw-slider fit; the side push lead screws 34 are arranged radially along the working turntable 1.

[0040] The side push slider 32 penetrates through the side push lead screw slider 33 in the horizontal direction and is slidably matched with the side push lead screw slider 33. The sliding direction of the side push slider 32 and the side push lead screw slider 33 forms an angle with the linear movement direction of the side push lead screw slider 33, and this angle is not a right angle. Preferably, a guide groove 321 is formed in the side push slider 32 along the length direction of the side push slider 32, and a guide post 331 protruding into the guide groove 321 is provided on the side push lead screw slider 33. The diameter of the guide post 331 corresponds to the width of the guide groove 321. A return spring 322 is arranged inside the guide groove 321. One end of the return spring 322 abuts against the groove wall of the guide groove 321, and the other end of the return spring 322 abuts against the guide post 331. When the side push slider 32 is driven by an external force to slide relative to the side push lead screw slider 33, the return spring 322 is compressed. After the external force is removed, under the elastic force of the return spring 322, the side push slider 32 slides back to its original position.

[0041] A limit head 36 is provided at one end of the side push platform 35 adjacent to the positioning table 11. The limit head 36 is preferably a limit bearing with a vertically arranged axis. The distance between the side push slider 32 and the limit head 36 is less than the distance between the side push lead screw slider 33 and the limit head 36. A side push lever 31 arranged radially along the working turntable 1 is fixed at one end of the side push slider 32 adjacent to the positioning table 11. The side push lever 31 is an elastic lever that can be slightly bent. To avoid position interference, the side push lever 31 and the limit head 36 are arranged with a height offset, and the side push lever 31 and the main push elastic ejector pins 23 are at the same height.

[0042] When the side push slider 32 and the side push lever 31 move linearly with the side push screw slider 33 and the side push slider 32 is not in contact, there is still a certain distance between the side push lever 31 and the positioning table 11 along the radial direction of the working turntable 1. The side push lever 31 moves linearly along the radial direction of the working turntable 1 to approach the side of the product 4 to be corrected. When the side push slider 32 abuts against the limit head 36, at this time, the side push lever 31 just moves to the side of the corresponding product 4 to be corrected, so as to be arranged oppositely to the second positioning block 113. After the side push slider 32 abuts against the limit head 36, when the side push screw slider 33 continues to move forward, relative sliding occurs between the side push slider 32 and the side push screw slider 33. During the sliding, under the action of the included angle, rolling cooperation occurs between the side push slider 32 and the limit head 36, and the side push lever 31 at the end of the side push slider 32 generates a horizontal displacement along the tangent direction of the working turntable 1, so as to move towards the second positioning block 113 and press the other end of the product 4 to be corrected against the second positioning block 113. After the main push correction mechanism 2 and the side push correction mechanism 3 press and position the product 4 to be corrected in sequence, the product 4 to be corrected is pressed and positioned from top to bottom through the pressing block 114, and then the main push correction mechanism 2 and the side push correction mechanism 3 are reset to wait for the next correction operation.
