Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of automation equipment, in particular to a multifunctional clamping, overturning and buckling device. BACKGROUND

[0002] For various electronic products in the prior art, during the process of assembling into finished products, various workpieces constituting them usually need to be fixed by dispensing glue liquid. For the workpieces needing dispensing, workpiece carrier plates are generally provided for positioning them. After dispensing, pressure holding cover plates are usually used to press and fix them to achieve shaping.

[0003] The front and rear ends of the pressure holding cover plate used are generally rotatably connected with buckling members. The front and rear ends of the workpiece carrier plate used are generally provided with buckling grooves for buckling the buckling members. During operation, the pressure holding cover plate is stacked on the workpiece carrier plate at appropriate front and rear positions and left and right positions, and then the two buckling members are buckled into the corresponding position buckling grooves, so that the workpiece placed on the workpiece carrier plate is press-fitted and fixed by the pressure holding cover plate.

[0004] As the prior art, the pressure holding cover plate is usually placed with its lower pressing surface upward to avoid the lower pressing surface being contaminated by stains on the table and then contaminating the workpiece when the lower pressing surface is pressed onto the upper surface of the workpiece. During operation, the operator needs to turn the pressure holding cover plate by 180 degrees so that the lower pressing surface faces downward, and then manually place the corresponding pressure holding cover plate on the workpiece carrier plate and manually buckle the two buckling members into the corresponding position buckling grooves to press and fix the workpiece placed on the workpiece carrier plate by the pressure holding cover plate.

[0005] For the above operation, the present patent inventor found that the following defects and deficiencies exist.

[0006] Specifically, on the one hand, the pressure holding cover plate is manually turned by 180 degrees and placed on the workpiece carrier plate. The level, front and rear position and left and right position of the pressure holding cover plate during placement are not easy to accurately control, and misalignment between the pressure holding cover plate and the workpiece carrier plate is likely to occur, so that the workpiece preassembled on the upper surface of the workpiece carrier plate cannot be accurately press-fitted and fixed as much as possible. On the other hand, when the placement position of the pressure holding cover plate is not accurate, the workpiece preassembled is likely to be damaged by manual movement of the pressure holding cover plate. The workpiece preassembled is likely to be damaged, and the pressure holding cover plate is usually relatively heavy. Manual turning and carrying of the pressure holding cover plate will consume a lot of manpower, increase the labor of the operator, and the dust and oil stains on the hands of the operator are likely to contaminate the surface of the workpiece preassembled, so that the workpiece preassembled is likely to become a defective product.

[0007] In view of this, the patent inventors, combined with experience, through in-depth thinking of the problems encountered in work, reading a large number of scientific research materials and literature, through retrieval novelty search, gradually conceived and designed the present application to solve the related technical problems.

The rotation shafts of the two buckling members 2001 are arranged along the left-right direction. The pressure retaining cover plate 2000 is provided with insertion holes 2002 at the left and right end faces thereof, respectively. The pressure retaining cover plate 2000 is formed with a workpiece pressing position 2003 in the middle of the upper end face thereof. The workpiece carrier plate 3000 is provided with buckling grooves 3001 at the front and rear ends thereof, respectively, for the buckling members 2001 to be buckled downward in relative position. The workpiece carrier plate 3000 is formed with a workpiece resting position 3002 in the middle of the upper end face thereof. Specifically, reference can be made to the accompanying drawings of the present application. Figure 1 and the accompanying Figure 2 drawings.

[0081] Based on this, reference can be made to the accompanying Figures 3 to 7 drawings.

[0082] The present application includes:

[0083] A fixing seat 10 is adapted to be fixed to a three-dimensional moving mechanism so as to move forward and backward, left and right, and up and down under the control of the three-dimensional moving mechanism.

[0084] A left grabbing member 20 is used to grab the left end of the pressure retaining cover plate 2000.

[0085] A right grabbing member 30 is used to grab the right end of the pressure retaining cover plate 2000.

[0086] Left and right driving mechanism 40; the left and right driving mechanism 40 is fixedly arranged at the bottom of the fixed seat 10, used to drive the left grabbing piece 20 and the right grabbing piece 30 to move towards each other to correspond to the left and right ends of the pressure retaining cover plate 2000, and used to drive the left grabbing piece 20 and the right grabbing piece 30 to move away from each other to correspond to the left and right ends of the pressure retaining cover plate 2000;

[0087] Left overturning mechanism 50; the left overturning mechanism 50 is fixedly arranged at the lower left part of the left and right driving mechanism 40, used to overturn the pressure retaining cover plate 2000 by 180 degrees so that the upper end face is turned downward; based on this, the left grabbing piece 20 of the application is fixedly arranged at the right part of the left overturning mechanism 50;

[0088] Right overturning mechanism 60; the right overturning mechanism 60 is fixedly arranged at the lower right part of the left and right driving mechanism 40, used to overturn the pressure retaining cover plate 2000 by 180 degrees together with the left overturning mechanism 50 so that the upper end face is turned downward; based on this, the right grabbing piece 30 of the application is fixedly arranged at the left part of the right overturning mechanism 60.

[0089] Based on the above, it can be clear that the application is mainly used as a multifunctional clamping, overturning and buckling device 1000 in specific implementation.

[0090] Specifically, when the application is applied, the pressure retaining cover plate 2000 to be grabbed is prearranged on a jig table, then the application is moved forward, backward, left, right, up and down to the appropriate position under the control of the three-dimensional moving mechanism used in combination, the left grabbing piece 20 and the right grabbing piece 30 are driven to move towards each other by the left and right driving mechanism 40 to correspond to the left and right ends of the pressure retaining cover plate 2000, then the left overturning mechanism 50 and the right overturning mechanism 60 are cooperated and rotated in the same direction to overturn the pressure retaining cover plate 2000 by 180 degrees so that the upper end face is turned downward, then the application is moved forward, backward, left, right, up and down to the appropriate position under the control of the three-dimensional moving mechanism used in combination to adhere the pressure retaining cover plate 2000 overturned by 180 degrees to the upper end face of the workpiece carrier plate 3000 from top to bottom, so that the workpiece pressing and fixing position 2003 is opposite to the workpiece resting position 3002, then the left grabbing piece 20 and the right grabbing piece 30 are driven to move away from each other by the left and right driving mechanism 40 to correspond to the left and right ends of the pressure retaining cover plate 2000, and the buckling pieces 2001 arranged at the front and rear ends of the pressure retaining cover plate 2000 are buckled into the buckling grooves 3001 arranged at the front and rear ends of the workpiece carrier plate 3000, so that the workpiece preloaded on the workpiece resting position 3002 on the upper end face of the workpiece carrier plate 3000 is fixed, and specific reference can be made to the drawings in the specification of the application. Figure 7

[0091] ​Obviously, for the application of this application, the use of mechanical automation control enables the pressure-holding cover plate 2000 to be rotated 180 degrees as accurately as possible so that its upper surface is rotated downwards, and to be in close contact with the upper surface of the workpiece carrier plate 3000 in the most accurate front-back and left-right positions, so that they are not easily misaligned. As a result, the workpiece pre-installed on the upper surface of the workpiece carrier plate 3000 can be pressed and fixed as accurately as possible, making the application highly reliable.

[0092] Furthermore, when the pressure-holding cover 2000 can be rotated 180 degrees as accurately as possible so that its upper surface is turned downwards, and when it can be in close contact with the upper surface of the workpiece carrier plate 3000 in the most accurate front-to-back and left-to-right positions, its placement position is precise. This allows the workpiece pressing position 2003 to be precisely aligned with the workpiece placement position 3002 without needing to be moved again, thus reducing the risk of wear on the workpiece pre-installed on the workpiece carrier plate 3000 at the workpiece placement position 3002. As a result, the pre-installed workpiece is less likely to be damaged by wear. Moreover, the pressure-holding cover 2000 is rotated and transported by mechanical automation control, which can greatly save the operator's physical strength and reduce operator fatigue. The operator's hands do not need to come into contact with it, so it is not easy to get dust and oil stains from the operator's hands. This makes the pressure-holding cover 2000 and the surface of the pre-installed workpiece have good anti-contamination effect, so the pre-installed workpiece is less likely to become a defective product.

[0093] Furthermore, through the above-mentioned optimized design, the whole constituted by this application is highly practical and has a good effect in use.

[0094] Furthermore, in specific implementation, in accordance with... Figures 3 to 6 As shown, according to an embodiment of the present invention, the left and right driving mechanism 40 includes a driving member A401, a left inverted L-shaped fixing member 402 and a right inverted L-shaped fixing member 403;

[0095] The driving component A401 is fixedly disposed in the middle of the lower bottom surface of the fixed base 10; the left inverted L-shaped fixing component 402 and the right inverted L-shaped fixing component 403 are both connected to the driving component A401, and the left flipping mechanism 50 is fixedly disposed in the lower left part of the left inverted L-shaped fixing component 402, and the right flipping mechanism 60 is fixedly disposed in the lower right part of the right inverted L-shaped fixing component 403.

[0096] Under the control of the driving component A401, the left inverted L-shaped fixing component 402 and the right inverted L-shaped fixing component 403 can move towards each other or away from each other.

[0097] Thus, under the control of the driving member A401, when the left inverted L-shaped fixing member 402 and the right inverted L-shaped fixing member 403 move towards each other by a preset stroke, the left grabbing member 20 and the right grabbing member 30 are driven to move towards each other by a preset stroke to correspondingly grab the left and right ends of the pressure maintaining cover plate 2000. Conversely, under the control of the driving member A401, when the left inverted L-shaped fixing member 402 and the right inverted L-shaped fixing member 403 move away from each other by a preset stroke to the initial state, the left grabbing member 20 and the right grabbing member 30 are driven to move away from each other by a preset stroke to correspondingly release the left and right ends of the pressure maintaining cover plate 2000.

[0098] Preferably, in the technical solution, the driving member A401 adopts a double-cylinder driving member to realize synchronous movement of the left inverted L-shaped fixing member 402 and the right inverted L-shaped fixing member 403 towards or away from each other. At this time, the driving member A401 has a left movable end and a right movable end which can move left and right. The left movable end of the driving member A401 is connected to the upper right part of the left inverted L-shaped fixing member 402, and the right movable end of the driving member A401 is connected to the upper left part of the right inverted L-shaped fixing member 403.

[0099] Further, in specific implementation, the left and right driving mechanisms 40 continue to be compared with Figures 3 to 6 As shown, according to one embodiment of the present application, the left and right driving mechanisms 40 further include a left sliding rail 404, a left sliding block 405, a right sliding rail 406, and a right sliding block 407.

[0100] The left sliding rail 404 is fixedly arranged on the lower bottom surface of the fixed seat 10 and located on the left side of the driving member A401. The left sliding block 405 is slidably arranged on the left sliding rail 404 and connected to the left inverted L-shaped fixing member 402.

[0101] The right sliding rail 406 is fixedly arranged on the lower bottom surface of the fixed seat 10 and located on the right side of the driving member A401. The right sliding block 407 is slidably arranged on the right sliding rail 406 and connected to the right inverted L-shaped fixing member 403.

[0102] Therefore, by additionally arranging the left sliding rail 404 and the left sliding block 405, the movement of the driving member A401 towards or away from the right inverted L-shaped fixing member 403 is stable and not prone to forward and backward displacement. Similarly, by additionally arranging the right sliding rail 406 and the right sliding block 407, the movement of the driving member A401 towards or away from the left inverted L-shaped fixing member 402 is also stable and not prone to forward and backward displacement.

[0103] Therefore, when the left and right driving mechanisms 40 further comprise the left sliding rail 404, the left sliding block 405, the right sliding rail 406 and the right sliding block 407, the left and right driving mechanisms 40 can operate more stably and reliably.

[0106] When the driving part A 401 controls the left inverted L-shaped fixing part 402 and the right inverted L-shaped fixing part 403 to move towards each other by a preset stroke, the right end of the left limit buffer 409 abuts against the left end face of the left sliding rail 404, and the left end of the right limit buffer 411 abuts against the right end face of the right sliding rail 406.

[0107] Therefore, the left and right positions of the left limit buffer 409 and the right limit buffer 411 can be adjusted according to the left and right widths of the pressure maintaining cover plate 2000, so that the preset stroke of the driving part A 401 controlling the left inverted L-shaped fixing part 402 and the right inverted L-shaped fixing part 403 to move towards each other is controllable. When the driving part A 401 controls the left inverted L-shaped fixing part 402 and the right inverted L-shaped fixing part 403 to move towards each other by a preset stroke to drive the left grabbing part 20 and the right grabbing part 30 to move towards each other by a preset stroke to correspondingly grab the pressure maintaining cover plate 2000 at both ends, the grabbing distance is controllable, which can better avoid the left grabbing part 20 and the right grabbing part 30 from damaging the pressure maintaining cover plate 2000, so that the overall use reliability of the present application is more optimal.

[0124] The pushing member 70 comprises a front pushing plate 701, a front pushing wheel 702, a rear pushing plate 703 and a rear pushing wheel 704. The front pushing plate 701 is vertically fixed at the lower front part of the fixed base 10. The front pushing wheel 702 is rotatably fixed at the bottom of the front pushing plate 701. The rear pushing plate 703 is vertically fixed at the lower rear part of the fixed base 10. The rear pushing wheel 704 is rotatably fixed at the bottom of the rear pushing plate 703. The rotation shafts of the front pushing wheel 702 and the rear pushing wheel 704 are arranged in the left-right direction.

[0125] In the actual application, when the pressure retaining cover plate 2000 is grabbed and turned by 180 degrees so that the upper end face thereof is turned downward and is attached to the upper end face of the workpiece loading plate 3000, and then the left grabbing member 20 and the right grabbing member 30 are driven by the left-right driving mechanism 40 to move away from each other to release the pressure retaining cover plate 2000, and then the application is controlled by the matched three-dimensional moving mechanism to move downward by a preset stroke, the front pushing wheel 702 can be driven to move downward by a preset stroke to press the clamping member 2001 arranged at the front end of the pressure retaining cover plate 2000 into the clamping groove 3001 arranged at the front end of the workpiece loading plate 3000. The rear pushing wheel 704 can be driven to move downward by a preset stroke to press the clamping member 2001 arranged at the rear end of the pressure retaining cover plate 2000 into the clamping groove 3001 arranged at the rear end of the workpiece loading plate 3000.

For the above-mentioned operation, the clamping members 2001 arranged at the front and rear ends of the pressure retaining cover plate 2000 are also automatically pressed into the clamping grooves 3001 arranged at the front and rear ends of the workpiece loading plate 3000 by the corresponding mechanical hand. Similarly, the operator's hand does not need to contact the clamping members 2001 to manually operate the clamping members 2001, so that the operator's hand is not easily contaminated by dust, oil stains and the like, the pollution prevention effect of the pressure retaining cover plate 2000 is achieved, and the operation efficiency and operation accuracy of the turning and pressing of the pressure retaining cover plate 2000 are greatly improved.

[0127] Therefore, the above-optimized design can further improve the overall use effect of the application.

[0128] It should be noted that, in specific implementation, referring to Figs. 1 to 3, Figure 4 and Figure 6 According to one embodiment of the application, the pushing member 70 further comprises a driving member D705.

[0129] The driving member D705 is fixedly arranged on the fixed base 10. The upper ends of the front pushing plate 701 and the rear pushing plate 703 are connected to the driving member D705.

[0130] Under the control of the drive unit D705, the front push plate 701 and the rear push plate 703 can move towards each other or away from each other.

[0131] Preferably, in this technical solution, the driving component D705 adopts a dual-cylinder driving component to control the front push plate 701 and the rear push plate 703 to move synchronously towards each other or synchronously away from each other. In this case, the driving component D705 has a front movable end and a rear movable end that can move back and forth. The front movable end of the driving component D705 is connected to the upper end of the front push plate 701, and the rear movable end of the driving component D705 is connected to the upper end of the rear push plate 703.

[0132] Therefore, by controlling the downward movement of this application by the matching three-dimensional moving mechanism, the front pushing wheel 702 is driven to move downward by a preset stroke to press the fastening member 2001 at the front end of the pressure-holding cover plate 2000 into the fastening groove 3001 at the front end of the workpiece carrier plate 3000, and the rear pushing wheel 704 is driven to move downward by a preset stroke to press the fastening member 2001 at the rear end of the pressure-holding cover plate 2000 into the fastening groove 3001 at the rear end of the workpiece carrier plate 3000. Simultaneously, the driving member D705 controls the front pushing plate 701 and the rear pushing plate 703 to move towards each other by a preset stroke, thus enabling better and faster pressing of the fastening member 2001 at the front end of the pressure-holding cover plate 2000 into the fastening groove 3001 at the front end of the workpiece carrier plate 3000, and better and faster pressing of the fastening member 2001 at the rear end of the pressure-holding cover plate 2000. 1. Pressed into the fastening groove 3001 provided at the rear end of the workpiece carrier plate 3000. This is because when the driving component D705 controls the front pushing plate 701 and the rear pushing plate 703 to move towards each other for a preset stroke, the fastening member 2001 provided at the front end of the pressure holding cover plate 2000 can be fully pushed backward into the fastening groove 3001 provided at the front end of the workpiece carrier plate 3000, and the fastening member 2001 provided at the rear end of the pressure holding cover plate 2000 can be pressed into the fastening groove 3001 provided at the front end of the workpiece carrier plate 3000. 01 is pushed forward and fully into the fastening groove 3001 provided at the rear end of the workpiece carrier plate 3000, so that the two fastening parts 2001 can be fastened into the corresponding positions of the two fastening grooves 3001 more quickly and reliably, so as to drive the pressure holding cover plate 2000 to be pressed more firmly on the workpiece carrier plate 3000 and make it less likely to loosen from each other, so that the workpiece pre-installed on the upper surface of the workpiece carrier plate 3000 will be pressed and fixed more stably.

[0133] And, in the initial state, under the control of the driving element D705, the front pushing plate 701 and the rear pushing plate 703 are preset to have a large gap between each other in the opposite movement stroke, at this time, the left grabbing element 20 and the right grabbing element 30 can be conveniently formed to avoid space to facilitate the turning of 180 degrees, in this way, the pushing element 70 provided by the application has good independence and good use reliability, and will not interfere with the left grabbing element 20 and the right grabbing element 30 in the opposite movement or synchronous turning of 180 degrees.

[0134] Further, the above optimization design enables the overall use effect of the application to be further improved.

[0138] Therefore, by providing the left stop block 2011, the left overturning limiting buffer 413, the right stop block 3011 and the right overturning limiting buffer 414, the overturning angle of the left grabbing piece 20 and the right grabbing piece 30 will be very accurate when they are overturned by 180 degrees, so that they are stable and reliable in use.
