Description

Technical Field

[0001] This utility model relates to the field of glass processing technology, specifically to a material feeding and alignment mechanism. Background Technology

[0002] In the glass processing industry, loading and alignment are crucial steps affecting processing accuracy and efficiency. Traditional glass alignment mechanisms often employ single-sided clamping or fixed limiting methods, which present the following problems:

[0003] The glass has poor size adaptability and is prone to displacement or breakage due to uneven force during clamping.

[0004] The alignment accuracy relies on manual adjustment, which is inefficient and cannot meet the needs of high-precision machining.

[0005] Without a multi-directional collaborative positioning mechanism, the glass is prone to secondary displacement when it moves to the preset position.

[0006] Furthermore, existing mechanisms are complex in structure, have high maintenance costs, and provide insufficient protection for the glass surface, making them prone to scratches. Therefore, there is an urgent need for an alignment mechanism capable of simultaneously clamping both ends of the glass, multi-directional fine adjustment, and flexible pushing, in order to improve automation levels and processing quality.

[0066] During operation, two pieces of glass are placed between two centering mechanisms on the base. The two sides of the centering mechanism move towards the glass simultaneously, and the clamping components at both ends of the mechanism flexibly clamp the glass from both ends, completing the initial centering. Subsequently, the two positioning mechanisms at the front end move towards the glass. Finally, the pushing mechanism smoothly advances along the base towards the positioning mechanism, so that the glass moves towards the positioning mechanism, allowing the positioning mechanism to abut against the side of the glass, further correcting the horizontal positional deviation. The entire process achieves automated alignment through mechanical linkage, balancing efficiency and accuracy, and is especially suitable for high-precision glass processing scenarios. After the glass has completed accuracy calibration, the centering mechanism, positioning mechanism, and pushing mechanism will move and reset.

[0067] By symmetrically moving the centering mechanisms on both sides, the glass ends are clamped and automatically centered, avoiding glass displacement or stress concentration caused by unilateral force application, thus improving clamping stability and safety. Combined with the edge abutment of the front positioning mechanism and the precise push of the rear pushing mechanism, a three-level positioning of "clamping-limiting-pushing" is formed, ensuring that the glass moves to the preset position without displacement, and significantly improving alignment accuracy. Through mechanical linkage, the clamping force is evenly distributed, avoiding hard impacts, reducing the risk of scratches or breakage on the glass surface, and ensuring a high yield rate.

[0091] The feeding and alignment mechanism of this utility model embodiment is described in detail below with reference to the accompanying drawings.

[0092] Please see Figures 1-8 In this embodiment, the system includes: a base 1 on which a workpiece can be placed; two centering mechanisms 2, which are respectively disposed opposite to each other on both sides of the base 1, and whose ends can move closer or further apart to clamp the ends of the workpiece on the base 1; two positioning mechanisms 3, which are respectively disposed at intervals on the base 1 and at the front ends of the two centering mechanisms 2, and whose ends can move toward the two centering mechanisms 2 to abut against the edge of the workpiece; and a pushing mechanism 4, which is disposed on the base 1 and at the rear ends of the two centering mechanisms 2, and whose pushing mechanism 4 can move toward the two centering mechanisms 2 to move the workpiece clamped by the two centering mechanisms 2 toward the two positioning mechanisms 3 to move the workpiece to a preset position.

[0093] The workpiece described above is glass. During operation, two pieces of glass are placed between two centering mechanisms 2 on the base 1. The two sides of the centering mechanism 2 move towards the glass simultaneously, and the clamping components at both ends of the mechanism 2 flexibly clamp the glass from both ends, completing the initial centering. Subsequently, the two front positioning mechanisms 3 move towards the glass respectively. Finally, the pushing mechanism 4 is smoothly pushed along the base 1 towards the positioning mechanism 3, so that the glass moves towards the positioning mechanism 3, and the positioning mechanism 3 abuts against the side of the glass, further correcting the horizontal positional deviation. The entire process achieves automated positioning through mechanical linkage, balancing efficiency and accuracy, and is especially suitable for high-precision glass processing scenarios.

[0094] By symmetrically moving the centering mechanisms 2 on both sides, the glass ends are clamped and automatically centered, avoiding glass displacement or stress concentration caused by unilateral force application, thus improving clamping stability and safety. Combined with the edge abutment of the front positioning mechanism 3 and the precise push of the rear pushing mechanism 4, a three-level positioning of "clamping-limiting-pushing" is formed, ensuring that the glass moves to the preset position without displacement, and significantly improving the alignment accuracy. The clamping force is evenly distributed through mechanical linkage, avoiding hard impacts, reducing the risk of scratches or breakage on the glass surface, and ensuring the yield rate of processed products.

[0095] Preferably, the centering mechanism 2 includes: two first slide rails 201, which are spaced apart within the base 1 and arranged along the width direction of the base 1; two first sliders 202, which are slidably mounted on the two first slide rails 201; a first fixing plate 203, which is mounted on the two first sliders 202; a first mounting block 204, which is located at the bottom of the first fixing plate 203 and between the two first sliders 202; a first linear nut 205, which is located in the middle of the first mounting block 204; two first limiting rods 206, which are located at both ends of the first mounting block 204 and are arranged along the width direction of the base 1; and a plurality of first stop rods 207, which are vertically mounted at equal intervals on the first fixing plate 203, and the tops of the plurality of first stop rods 207 extend to the base 1.

[0096] The centering mechanism 2 further includes: two second sliders 208, which are slidably mounted on two first slide rails 201 and spaced apart from the two first sliders 202; a second fixing plate 209, which is mounted on the two second sliders 208; a second mounting block 210, which is located at the bottom of the second fixing plate 209 and between the two second sliders 208; a second linear nut 211, which is located in the middle of the second mounting block 210; two second limiting rods 212, which are located at both ends of the second mounting block 210 and are arranged along the width direction of the base 1, and correspond to the two first limiting rods 206; and a plurality of second stop rods 213, which are vertically mounted on the second fixing plate 209 at equal intervals, and the tops of the plurality of second stop rods 213 extend to the base 1.

[0097] The centering mechanism 2 further includes: a mounting plate 214, which is disposed on the side of the base 1; a first motor 215, which is disposed inside the mounting plate 214, and the drive shaft of the first motor 215 extends through the mounting plate 214 to the outside of the mounting plate 214; a first rotating wheel 216, which is connected to the drive shaft of the first motor 215; a bearing seat 217, which is disposed inside the base 1; a lead screw 218, the first end of which is rotatably connected to the bearing seat 217, and the second end of which passes through the first linear nut 205 and the second linear nut 211 and extends to the outside of the base 1; a second rotating wheel 219, which is connected to the second end of the lead screw 218; and a first belt 220, which is sleeved on the first rotating wheel 216 and the second rotating wheel 219.

[0098] The two ends of the lead screw 218 are respectively provided with a first thread and a second thread, the first thread and the second thread have opposite rotation directions, the first thread is rotatably connected to the first linear nut 205, and the second thread is rotatably engaged with the second linear nut 211;

[0099] After the glass is placed on the base 1, the first motor 215 drives the lead screw 218 to rotate via a belt. Due to the reverse thread design at both ends of the lead screw 218, the first linear nut 205 and the second linear nut 211 respectively drive the two first sliders 202 and the two sliders to move synchronously towards each other along the first slide rail 201. The first stop 207 fixed to the first fixed plate 203 and the second stop 213 fixed to the second fixed plate 209 clamp the glass from both sides. The movement range is constrained by the limit rod to ensure that the glass is subjected to uniform force at both ends and complete the automatic centering. The evenly spaced distribution of the stop rods is suitable for glass of different sizes. When clamping, it only contacts the edge of the glass to avoid surface scratches. The reverse thread lead screw 218 drives the two sets of sliders to move synchronously, eliminating the tilting or displacement of the glass caused by unilateral force application, improving the centering accuracy, and is suitable for high-precision scenarios such as ultra-thin glass. It realizes the full automation of glass clamping, centering and positioning, and solves the pain points of uneven clamping, excessive manual intervention and easy damage to glass in traditional mechanisms. It is particularly suitable for precision processing fields such as display panels and optical glass.

[0100] In this embodiment, the positioning mechanism 3 includes: a mounting base 301, which is disposed on the base 1; two third slide rails 302, which are respectively disposed at both ends of the mounting base 301 and are oriented towards the centering mechanism 2; two third sliders 303, which are slidably disposed on the two third slide rails 302; a third fixing plate 304, which is disposed on the two third sliders 303; a plurality of third stop rods 305, which are vertically disposed at equal intervals on the third fixing plate 304; and a cylinder 306, which is disposed on the mounting base. Inside 301, the transmission end of cylinder 306 is connected to the third fixed plate 304; after the glass is clamped by the centering mechanism 2, cylinder 306 is in a retracted state, and the third stop 305 is away from the edge of the glass; the piston rod of cylinder 306 extends, pushing the third fixed plate 304 to move along the third slide rail 302 toward the glass; multiple third stop 305s simultaneously open the edge of the glass, and then the pushing mechanism 4 pushes the glass toward the direction of the third stop 305 so that the edge of the glass abuts against the third stop 305. By having multiple third stop 305s simultaneously abut against the edge of the glass, the lateral position deviation of the glass is corrected by uniformly applying pressure.

[0101] In this embodiment, the pushing mechanism 4 includes: two support plates 401, which are disposed within the base 1 and oriented toward the centering mechanism 2; two fourth slide rails 402, which are respectively disposed on the two support plates 401 and oriented along the length of the two support plates 401; two fourth sliders 403, which are slidably disposed on the two fourth slide rails 402; a fourth fixing plate 404, which is disposed on the two fourth sliders 403; and two connecting plates 405, which are respectively disposed at both ends of the fourth fixing plate 404 and oriented toward the centering mechanism 2. Two abutment components 406 are respectively disposed on two connecting plates 405; a second motor 407 is vertically disposed at the bottom of the base 1, and the drive shaft of the second motor 407 extends into the base 1; a third rotating wheel 408 is disposed on the second motor 407 and is connected to the second motor 407 in a transmission manner; a fourth rotating wheel 409 is rotatably disposed in the base 1 and is spaced apart from the third rotating wheel 408; a second belt 410 is sleeved on the third rotating wheel 408 and the fourth rotating wheel 409; a connector 411 is connected at one end to the fourth fixing plate 404 and at the other end to the second belt 410;

[0102] After the centering mechanism 2 clamps the glass, the pushing mechanism 4 is located at the rear end of the base 1, maintaining a safe distance between the abutment component 406 and the glass. The second motor 407 drives the third rotating wheel 408 to rotate, which in turn drives the fourth rotating wheel 409 to rotate synchronously via the second belt 410. The connecting piece 411 moves with the belt, pulling the fourth fixing plate 404 to move linearly along the fourth slide rail 402 towards the centering mechanism 2 (i.e., the glass direction), so that the glass is pushed towards the positioning mechanism 3, so that the end of the glass near the abutment component 406 and the end near the positioning mechanism 3 can be aligned. The two fourth slide rails 402 are arranged in parallel to ensure that the pushing mechanism 4 moves only in a single direction, meeting the requirements for precise glass alignment.

[0103] In this embodiment, the abutment component 406 includes: a fixing block 4061, which is disposed on the connecting plate 405; two mounting grooves 4062, which are respectively disposed at both ends of the fixing block 4061 and extend through the end face of the fixing block 4061 along its width direction; two sleeves 4063, which are respectively disposed in the two mounting grooves 4062; and two sliding rods 4064. 4. Slidingly disposed within two sleeves 4063 respectively; abutting block 4065, the abutting block 4065 being connected to the first end of two sliding rods 4064; two limiting blocks 4066, the two limiting blocks 4066 being disposed at the second end of two sliding rods 4064 respectively; two springs 4067, the two springs 4067 being respectively sleeved on two sliding rods 4064, and one end of each spring 4067 being connected to the abutting block 4065 respectively, and the other end being connected to the end face of each spring 4067 respectively;

[0104] When the pushing mechanism 4 moves, the abutment block 4065 contacts the rear end face of the glass, and the slide rod 4064 begins to slide into the sleeve 4063. The spring 4067 is compressed and contracts, converting the mechanical impact force into elastic potential energy, thus preventing the glass from breaking due to rigid collision. After the spring 4067 is compressed to an equilibrium state, the abutment block 4065 transmits a stable thrust through the slide rod 4064, pushing the glass towards the positioning mechanism 3. When the pushing mechanism 4 retracts, the spring 4067 releases energy, pushing the slide rod 4064 to reset, and the abutment block 4065 disengages from the glass. The deformation of the spring 4067 absorbs the instantaneous impact force, preventing the glass from cracking due to instantaneous impact. The sleeve 4063 restricts the slide rod 4064 to move only along the axial direction, preventing the abutment block 4065 from deflecting and scratching the glass surface, thus protecting the high-gloss glass. Through the mechanical buffer design of "spring 4067, slide rod 4064 + sleeve 4063 guidance", dynamic and compliant control is achieved during the glass workpiece pushing process, protecting the integrity of the glass and adapting to diverse working conditions.

[0105] In this embodiment, the base 1 is provided with a plurality of equally spaced first sliding grooves 101 and a plurality of equally spaced second sliding grooves 102. A first stop bar 207 is disposed in the first sliding groove 101 and a second stop bar 213 is disposed in the second sliding groove 102. The first stop bar 207 and the second stop bar 213 of the centering mechanism 2 move synchronously along the first sliding groove 101 and the second sliding groove 102 respectively. The sliding groove guides the stop bar to slide along a fixed path to ensure that the distance between the stop bars on both sides is adjusted evenly. The bottom of the stop bar is embedded in the sliding groove to eliminate lateral sway and ensure that the clamping force direction is always perpendicular to the glass edge to avoid stress concentration caused by tilting.

[0106] In this embodiment, the base 1 is also provided with a plurality of protrusions 103, which are equally spaced. The equally spaced protrusions 103 ensure that the glass contacts the base 1 only through a plurality of discrete protrusions 103, reducing the contact area of ​​the planar support and significantly reducing friction scratches (especially for high-gloss glass, such as mobile phone cover glass or optical lenses). The surface of the protrusions 103 can be coated with silicone, polyurethane or Teflon to avoid hard contact damage to the glass surface, while providing moderate anti-slip force. The spacing of the protrusions 103 is optimized according to the glass thickness to ensure that the weight of the glass is evenly distributed and to prevent microcracks caused by local bending stress.
