Description

Technical Field

[0001] This invention relates to the field of glass feeding equipment technology, and specifically to a flip-adsorption type glass feeding device for laser cleaving processing. Background Technology

[0002] In the production processes of display panels, photovoltaic glass, and other fields, glass laser cleaving is a core process for achieving precise glass cutting. The degree of automation, adaptability, and positioning accuracy of the glass loading stage before processing directly determine the subsequent cleaving quality and overall production efficiency.

It cannot adaptively adjust according to the glass size and stacking angle. The fixed-angle adsorption component cannot accurately fit with the glass surface, which easily leads to uneven adsorption force and increases the risk of glass falling off.

Detailed Implementation

[0030] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but the present invention can be implemented in many different ways as defined and covered by the claims.

[0031] like Figures 1-7 As shown, a flip-adsorption type glass feeding device for laser dicing includes a fixed base plate 1, a transmission mechanism 2 is provided on the fixed base plate 1, an adsorption gripping mechanism 3 is provided on both sides of the fixed base plate 1 located on the transmission mechanism 2, and a placement rack for storing glass is symmetrically provided on both sides of the fixed base plate 1.

[0032] Using the above scheme, the glass to be processed is neatly stacked on the placement rack during operation. The adsorption and gripping mechanisms 3 set on both sides alternately grip the glass in the placement rack and place it on the transmission mechanism 2. The adsorption and gripping mechanisms 3 on both sides work alternately. When the adsorption and gripping mechanism 3 on one side completes the feeding, it immediately returns to the feeding position, and the adsorption and gripping mechanism 3 on the other side starts the glass gripping at the same time to ensure that the feeding process is continuous and uninterrupted. The transmission mechanism 2 drives the glass to move towards the laser cleaving equipment.

[0033] The transmission mechanism 2 includes multiple sets of fixed plates 21 symmetrically arranged along the length of the fixed base plate 1. A transmission roller 22 is symmetrically arranged between two opposing fixed plates 21 via a bearing. A drive assembly 23 is provided on the transmission roller 22 and the drive assembly 23 is provided on the fixed base plate 1.

[0034] The cooperation between the fixed plate 21 and the drive assembly 23 can drive the transmission roller 22 to rotate during operation, while also providing space for the flipping movement of the adsorption gripping mechanism 3, ensuring that the adsorption gripping mechanism 3 can smoothly grip the glass without hindering the rotation of the transmission roller 22.

[0035] The drive assembly 23 includes a driven wheel 231 mounted on the transmission roller 22, a linkage rod 232 mounted on the outer wall of the fixed plate 21 via a bearing, a linkage wheel 233 and a drive wheel 234 mounted sequentially on the linkage rod 232, the driven wheel 231 and the linkage wheel 233 connected by a linkage belt 235, and a drive belt 236 connected between the drive wheels 234, and a drive motor mounted on the fixed base plate 1 via a motor mount, the drive motor being connected to start one of the drive wheels 234;

[0036] By adopting the above-mentioned mechanism, the adsorption and gripping mechanism 3 places the glass onto the transmission roller 22, starts the drive motor, and drives the drive wheel 234 to rotate during operation. The drive wheel 234 drives the linkage rod 232 to rotate synchronously through the interaction between the drive wheel 233, the driven wheel 231 and the linkage belt 235 during operation. During the rotation of the linkage rod 232, the transmission roller 22 is controlled to rotate through the interaction between the linkage wheel 233, the driven wheel 231 and the linkage belt 235, thereby moving the glass.

[0037] The adsorption and gripping mechanism 3 includes a fixed base 31 mounted on a fixed plate 21, a mounting rod 32 mounted between the fixed bases 31 via bearings, a gripping frame 33 mounted on the mounting rod 32, a control lever 37 mounted on the gripping frame 33, a gripping cylinder 34 mounted between the control lever 37 and the fixed plate 21, an execution adjustment component 35 mounted on the gripping frame 33 located between the two fixed plates 21, and an adsorption component 36 mounted on the execution adjustment component 35.

[0038] By adopting the above technical solution, the gripping cylinder 34 first outputs power, and transmits torque through the control lever 37 rigidly connected to the gripping frame 33, driving the gripping frame 33 to rotate around the mounting rod 32. This rotation causes the gripping frame 33 to deflect towards the placement rack until the adsorption component 36 enters the working range of the glass to be gripped, completing the initial approach action. During this process, the extension and retraction of the gripping cylinder 34 can be preset and adjusted according to the glass stacking height on the placement rack to ensure the consistency of the initial approach position. During the rotation, the gripping frame 33 accurately passes through the preset gap between the fixed plates 21 on both sides of the transmission mechanism 2. The adsorption gripping mechanism can adjust the spatial position and angle of the adsorption component by executing the adjustment component 35 according to the size, thickness and stacking angle of the glass to be gripped, ensuring that the adsorption component can accurately fit with the glass surface. This can overcome the problem that a single fixed adsorption structure cannot adapt to multiple specifications of glass, and realize universal gripping of glass with different parameters.

[0039] The execution adjustment component 35 includes an adjustment frame 351 mounted on the gripping frame 33. An adjustment link 352 is mounted on the upper side of the adjustment frame 351 via a pin, and an adjustment bracket 353 is mounted on the lower side of the adjustment frame 351 via a pin. An adsorption frame 354 is mounted between the adjustment link 352 and the adjustment bracket 353 via a pin. Adjustment grooves 355 are symmetrically opened on the adjustment bracket 353. An adjustment column 356 is slidably mounted in the adjustment groove 355. A control component 4 is mounted on the gripping frame 33 and is connected to the adjustment column 356.

[0040] The control component 4 includes a control cylinder 41 mounted on the gripper frame 33, a control connecting plate 42 mounted on the control cylinder 41, and a control connecting rod 43 connected to the adjusting column 356 on the control connecting plate 42.

[0041] By adopting the above technical solution, the control cylinder 41 outputs linear driving force, and through the force transmission of the control connecting plate 42 and the control link 43, the adjusting column 356 is driven to slide along the adjusting groove 355 of the adjusting frame 353. The sliding motion of the adjusting column 356 is converted into the rotational motion of the adjusting frame 353 around the connecting pin of the adjusting frame 351. At the same time, through the coordinated rotation of the adjusting link 352, the adsorption frame 354 drives the adsorption assembly 36 to complete the angle adjustment.

[0042] The adsorption assembly 36 includes a fixed suction cup 361 mounted on an adsorption frame 354. Sliding grooves are evenly distributed along the length of the adsorption frame 354. Sliding blocks 362 are slidably disposed within the sliding grooves. A connecting bracket is provided between two sliding blocks 362. A movable suction cup 364 is mounted on each sliding block 362. An extension frame 365 is mounted on the adsorption frame 354. Two extension frames 365 located in the middle are connected by a horizontal plate 366. An adjustment control 5 is mounted on the horizontal plate 366 and connected to the sliding blocks 362. A locking element 6 is mounted on the end of the horizontal plate 366 facing away from the adjustment control 5. Rectangular grooves 367 are provided on each of the two sliding blocks 362. A positioning hole 368 communicating with the rectangular grooves 367 is provided on each sliding block 362. A sliding frame 369 is mounted on the adsorption frame 354, passing through the rectangular grooves 367, and the sliding blocks 362 are slidably connected to the sliding frame 369.

[0043] The control unit 5 includes a control cylinder 51 set on the horizontal plate 366, a control plate 52 installed on the control cylinder 51, a control rod 53 set on the control plate 52, and the control rod 53 connected to the sliding block 362.

[0044] By adopting the above technical solution, according to the specifications of the glass to be grasped, the control cylinder 51 is activated to drive the control rod 53 on the control plate 52 to move linearly. When the control plate 52 moves, the control rod 53 simultaneously vibrates the sliding block 362 to move along the length of the sliding frame 369. If the glass size is large, the control rod 53 drives the sliding block 362 to move away from the fixed suction cup 361, increasing the distance between the moving suction cup 364 and the fixed suction cup 361. If the glass size is small, the control rod 53 drives the sliding block 362 to move closer to the fixed suction cup 361, reducing the distance between the moving suction cup 364 and the fixed suction cup 361. The distance between the fixed suction cup 364 and the movable suction cup 361 is such that the fixed suction cup 361 and the movable suction cup 364 are respectively connected to existing air pumps. The working status of the fixed suction cup 361 and the movable suction cup 364 during operation can be controlled by different suction pumps. The locking member 6 has two locking states during operation. In the first locking state, the locking member 6 can fix the sliding block 362 on the sliding frame 369 to ensure the stability of the distance between the fixed suction cup 361 and the movable suction cup 364. In the second locking state, the locking member 6 can lock the working status of the adjustable frame 351 to improve the stability of glass adsorption and gripping.

[0045] After the adsorption and gripping mechanism 3 moves the glass to the transfer roller 22, the locking part 6 returns to its initial state. At this time, the air pump connected to the fixed suction cup 361 stops working. According to the position of the glass on the transfer roller 22, the adjustment control 5 starts working, driving the sliding block 362 to move along the length of the sliding frame 369. The moving suction cup 364 moves synchronously with the sliding block, using its adsorption force with the glass surface to drive the glass to be translated and adjusted on the transfer roller 22, so that the edge of the glass is aligned with the processing baseline of the laser cleaving machine, so that the transported glass can meet the processing requirements of the laser cleaving machine.

[0046] The locking component 6 includes a locking cylinder 61 mounted on a horizontal plate 366, a locking connecting plate 62 mounted on the locking cylinder 61, a pressing rod 63 mounted on the locking connecting plate 62, a sliding cavity 64 formed on the sliding frame 369, the pressing rod 63 slidably disposed within the sliding cavity 64, and locking holes 65 evenly distributed along the length of the sliding frame 369 communicating with the sliding cavity 64. Locking rods 66 are movably disposed within the locking holes 65, and the locking rods 66 are connected to each other by a locking plate 67. A return spring 68 is provided between the inner walls of the interactive cavity. A fitting rod 69 is provided on the locking plate 67. The fitting rod 69 abuts against the pressing rod 63. The pressing rod 63 is provided with a stepped protrusion 610. Limiting holes 611 are evenly provided on the adjusting connecting rod 352 and the adjusting frame 353. The protrusion 610 has two steps. When the first step contacts the fitting rod 69, the locking member 6 is in the first locking state. When the second step contacts the fitting rod 69, the locking member 6 is in the second locking state.

[0047] Using the above technical solution, during operation, the locking cylinder 61 drives the pressing rod 63 on the locking connecting plate 62 to slide along the sliding cavity 64 of the sliding frame 364; the first step of the protrusion 610 on the pressing rod 63 presses against the fitting rod 69 during the sliding process, causing the locking plate 67 to compress the return spring 68; the locking rod 66 on the locking plate 67 is inserted into the positioning hole 368 of the sliding block along the locking hole 65 of the sliding frame, realizing the rigid fixation of the sliding block 362 and the sliding frame 369. After locking, the sliding block 362 thus determines the location of the moving suction cup. At position 364, if further improvement in gripping stability is required, such as when gripping thin or heavy glass, the locking cylinder 61 is activated to drive the squeezing rod 63 to continue sliding, so that the second step position of the protrusion 610 contacts the bonding rod 69. In this state, the locking rod 66 passes through the sliding frame 369 and is inserted into the limiting hole 611 of the adjusting rod 352 and the adjusting bracket 353 of the execution adjustment component 35, thereby achieving dual locking of the position of the sliding block 362 and the angle of the adsorption frame 354, and preventing the overall angle of the adsorption component from shifting during the gripping process.

[0048] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
