Description

Technical Field

[0001] The present invention relates to the technical field of chip placement machines, in particular to an improved chip placement machine with a basket for taking chips. Background Art

[0002] Polarizers are an indispensable material in the liquid crystal display industry, and each LCD glass panel needs to be attached with a polarizer.

[0003] When loading polarizers, the conventional placement machine first stacks multiple polarizers in a basket, then places the basket on a predetermined station on the machine. However, residual adhesive and dirt often cling to the edges of the polarizers, making it easy for the upper and lower polarizers to stick together. Furthermore, the insufficient wind power of the ion wind bar results in the following drawbacks when removing the polarizers:

[0004] (1) It is easy to cause the excess polarizer to be thrown out of the basket, resulting in serious material throwing from the machine;

[0005] (2) The polarizer cannot be effectively positioned when it is transported to the pre-alignment platform, resulting in vacuum anomalies and frequent machine alarms;

[0006] (3) The polarizer loss rate is high, which affects the equipment's utilization rate, stability and product yield. Summary of the Invention

[0007] In order to solve the technical problems raised in the background technology, the present invention provides an improved chip placement machine with a basket for taking chips.

The driving assembly is arranged in the first cylinder and can drive the second cylinder to rotate relative to the first cylinder before taking the film. The input end of the transmission assembly rotates synchronously with the second cylinder, so that its output end drives the blowing assembly and the ion wind rod to move together along the circumference direction of the outer edge of the polarizer. The blowing assembly can blow away the adhesive scale attached to it along the path direction of the outer edge of the polarizer, and the ion wind rod can remove static electricity in the polarizer.

[0014] As a further improvement of the above-mentioned scheme, the driving assembly includes a driving motor, which is installed on the top of the second hanging plate and accommodated in the first cylinder. A first gear coaxial with the first cylinder is fixed on the output shaft of the driving motor, and a second gear meshing with the first gear is provided in the first cylinder. An annular rack is coaxially fixed to the top of the second cylinder, and the second gear part protrudes out of the first cylinder to mesh with the annular rack.

[0015] As a further improvement to the above solution, the transmission assembly includes a first connecting rod radially fixed to the outer peripheral side wall of the second cylinder, a second connecting rod coaxial with the first connecting rod is elastically inserted at the centrifugal end thereof, a third connecting rod vertically downward is fixed at the centrifugal end of the second connecting rod, and the blowing assembly is mounted at the bottom of the third connecting rod;

[0016] A limiting rod is fixed downward on the outer side of the second connecting rod, which is parallel to the third connecting rod and extends to the bottom of the first connecting rod. The first connecting rod is provided with a clearance groove for the limiting rod to move axially relative to the first connecting rod; the top of the second hanging plate is detachably provided with a limiting groove surrounding the outside of the first cylinder, and the outer side wall of the limiting rod and the inner circumferential groove wall of the limiting groove are movably extruded and fitted.

[0017] As a further improvement of the above solution, the shape structure of the limiting groove is adapted to the shape structure of the polarizer accommodated in the basket.

[0018] As a further improvement of the above solution, a first roller is installed at the bottom of the limiting rod, and the limiting rod is rolled and extruded with the inner peripheral groove wall of the limiting groove through the first roller.

[0019] As a further improvement of the above solution, the centrifugal end of the first connecting rod is provided with a sliding groove extending along its axial direction, and the sliding groove is connected to the give way groove. The centripetal end of the second connecting rod is inserted into the sliding groove and is connected to the corresponding groove wall of the sliding groove through a first spring.

[0020] As a further improvement of the above solution, the blowing component is a blowing pipe, and the output end of the blowing pipe is directed toward the outer edge of the uppermost polarizer in the basket.

[0021] As a further improvement of the above solution, the top of the material basket is open and has a storage space for accommodating the polarizer inside. A carrier plate is elastically supported in the material basket, and the polarizer is stacked on top of the carrier plate.

[0022] As a further improvement of the above solution, the method for taking slices from the basket includes the following steps:

[0023] S1. Move the second hanging plate down to the top of the basket, and use the electric push rod to adjust the electric suction cup to touch the uppermost polarizer in the basket;

[0024] S2. Using a driving assembly to drive the second cylinder to rotate relative to the first cylinder, and using a transmission assembly to move the blowing assembly and the ion wind rod along the circumference of the outer edge of the polarizer, so as to blow away residual glue and dirt attached along the path of the outer edge of the polarizer and remove static electricity in the polarizer;

[0025] S3. Use the electric suction cup to suck up the polarizer on the top to remove the glue dirt and static electricity, and use the electric push rod to adjust the electric suction cup to move upward to complete the removal of the polarizer.

[0026] Compared with the prior art, the present invention has the following beneficial effects:

[0027] 1. The improved chip mounter with basket-taking function of the present invention can effectively blow away the adhesive dirt on the outer edge of the polarizer in the basket by adding a film-taking device to the machine, and cooperates with the ion wind rod to remove static electricity, so that the polarizers can be separated one by one when taking out the films, avoiding adhesion and throwing of materials, so as to facilitate smooth positioning and eliminate the situation where vacuum abnormalities cause frequent machine alarms. At the same time, it also plays a role in cleaning the surface of the polarizer, improving production efficiency, greatly reducing the loss of production auxiliary materials, and also improving equipment utilization rate, stability and product yield.

[0028] 2. The improved chip placement machine for picking up films with a basket of the present invention can adapt to any shape structure of the polarizer to be picked up for film picking through the first hanging plate, the second hanging plate, the driving assembly, the transmission assembly, the blowing assembly, and the ion wind rod in the film picking mechanism. That is, it is only necessary to select a limit groove with the same shape and size structure as the above-mentioned arbitrary shape structure polarizer and install it on the second hanging plate. Then, with the rotation of the output shaft of the driving motor and through the limiting cooperation of the transmission assembly, the circumferential rotation of the first connecting rod and the second connecting rod can be converted into a movement that can keep the third connecting rod and the blowing pipe and the ion wind rod thereon always in the direction of the peripheral edge of the polarizer of the shape structure, thereby achieving that the output end of the blowing pipe is always close to and aligned with the peripheral edge of the polarizer, so as to accurately blow away the adhesive scale attached to the edge of the polarizer, and also achieve that the output end of the ion wind rod is always close to the corresponding area of ​​the polarizer, so as to remove static electricity. It is convenient and practical, and improves production efficiency and yield rate.

[0029] 3. The improved chip placement machine for taking out polarizers from the basket of the present invention can prevent the polarizers in the basket from accidentally falling out of the basket and causing damage when the polarizers are not taken out, through the positioning rod, positioning groove and baffle. When the positioning rod is inserted into the positioning groove, the baffle will automatically deflect to a vertical state to facilitate subsequent film taking operations.

[0030] 4. The improved chip placement machine with basket for taking out chips of the present invention can clamp the basket on the machine before taking out chips by means of the positioning rod, positioning slot, clamping rod, wire wheel and traction rope. When the positioning rod is inserted into the positioning slot, the basket can be clamped and fixed on the machine before taking out chips, thereby improving the accuracy of positioning and preventing the basket from shaking when taking out chips and interfering with the chip taking operation.

[0038] The present invention will be further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0039] Example 1

[0040] Please combine Figures 1 to 4 The improved chip placement machine with a basket for picking up chips includes a machine platform 1, a chip picking device, a film tearing mechanism, and an attaching mechanism.

[0041] The film removal device is mounted on the machine 1 and includes a basket 2 and a film removal mechanism. The mechanism, located above the basket 2, is used to remove the polarizers pre-stored in the basket one by one. The basket 2 has an open top and contains a storage space for the polarizers. A carrier plate 3 is elastically supported within the basket 2. The carrier plate 3 and the basket 2 are connected by a second spring (not shown). To maintain the stability of the carrier plate 3, the second spring is mounted on the outside of a telescopic rod (not shown). The ends of the rod are fixed to the bottom of the carrier plate 3 and the bottom of the basket 2, respectively. The polarizers are stacked on top of the carrier plate 3.

[0042] In this embodiment, the second spring elastically supports the carrier plate 3. Whenever a polarizer is removed, the total weight of the remaining stacked polarizers will decrease accordingly, and the elastic force of the second spring can be released accordingly to push the carrier plate 3 and the remaining polarizers toward the opening of the basket 2, ensuring that the top polarizer can always be flush with the opening, so as to facilitate the subsequent blowing off of glue stains and static electricity on the polarizers and the removal of the polarizers.

[0043] The film-tearing mechanism is mounted on platform 1 and is capable of applying an easy-to-tear adhesive to each polarizer removed, removing the release film from the polarizer. The attaching mechanism is also mounted on platform 1 and is capable of sequentially attaching each polarizer, after the release film has been removed, to the LCD on the LCD platform, completing the polarizer-to-LCD attaching process.

[0044] The film removal mechanism includes a first hanger plate 4, a second hanger plate 6, a drive assembly, a transmission assembly, an air blowing assembly, and an ion wind rod. The first hanger plate 4 is suspended above the second hanger plate 6. A drive arm 5 is mounted on top of the first hanger plate 4, which moves the polarizing film removed by the film removal mechanism to the film tearing mechanism. The top of a first cylinder 7 is fixed to the bottom of the first hanger plate 4, connecting the first and second hanger plates 4 and ensuring synchronized movement. The drive arm 5 is hydraulically driven by the hydraulic system on the machine platform 1.

[0045] The blowing component is a blowing pipe 17, and the output end of the blowing pipe 17 is directed toward the outer edge of the uppermost polarizer in the basket 2. The air source of the blowing pipe 17 can be provided by a micro air pump housed in the pipe body.

[0046] An electric push rod 23 is mounted at the bottom of the second hanging plate 6. An electric suction cup 22 is mounted on the output end of the electric push rod 23. The distance between the electric suction cup 22 and the polarizer can be adjusted by the electric push rod 23. A first cylinder 7 is vertically fixed to the top of the second hanging plate 6. A second cylinder 11 is rotatably mounted on the outer side of the first cylinder 7. The second cylinder 11 is connected to the first cylinder 7 via a bearing, allowing the second cylinder 11 to rotate relative to the first cylinder 7.

[0047] The driving component is arranged in the first cylinder 7, and can drive the second cylinder 11 to rotate relative to the first cylinder 7 before taking the film. The input end of the transmission component rotates synchronously with the second cylinder 11, so that its output end drives the blowing component and the ion wind rod 18 to move along the circumference direction of the outer edge of the polarizer. The blowing component can blow away the residual glue and dirt attached to the path direction of the outer edge of the polarizer. The ion wind rod 18 can remove static electricity in the polarizer, thereby realizing the separation of the polarizers one by one to avoid adhesion.

[0048] The drive assembly includes a drive motor 8, which can be a reduction motor. The drive motor 8 is mounted on the top of the second hanging plate 6 and housed in the first cylinder 7. A first gear 9 coaxial with the first cylinder 7 is fixed to the output shaft of the drive motor 8. The first cylinder 7 is provided with a second gear 10 meshing with the first gear 9. An annular rack 13 is coaxially fixed to the top of the second cylinder 11. Part of the second gear 10 protrudes out of the first cylinder 7 to mesh with the annular rack 13.

[0049] In this embodiment, a movable groove (not marked) connecting the inside and the outside is opened on the wall of the first cylinder 7, and part of the wheel body of the second gear 10 protrudes from the outside of the first cylinder 7 through the movable groove, thereby engaging with the gear teeth of the annular rack 13 for transmission.

[0050] The transmission assembly includes a first connecting rod 14 radially fixed to the outer peripheral side wall of the second cylinder 11. A second connecting rod 15 coaxial with the first connecting rod 14 is elastically inserted at the centrifugal end. A third connecting rod 16 is fixed vertically downward at the centrifugal end of the second connecting rod 15. The third connecting rod 16 moves synchronously with the second connecting rod 15. The blowing assembly is installed at the bottom of the third connecting rod 16.

[0051] In this embodiment, the centrifugal end of the first connecting rod 14 defines a chute (not shown) extending along its axial direction. The chute communicates with the clearance groove. The centrifugal end of the second connecting rod 15 is inserted into the chute and connected to the corresponding groove wall of the chute via a first spring. The first spring provides a constant squeezing force on the second connecting rod 15, ensuring that the centrifugal end of the second connecting rod 15 tends to move in the centrifugal direction.

[0052] A stopper rod 19 is fixed downwardly to the outside of the second connecting rod 15, parallel to the third connecting rod 16 and extending below the first connecting rod 14. The first connecting rod 14 is provided with a clearance groove that allows the stopper rod 19 to move axially relative to the first connecting rod 14. A stopper groove 21 is detachably provided on the top of the second hanging plate 6, surrounding the outside of the first cylinder 7. The outer wall of the stopper rod 19 is movably pressed into the inner wall of the stopper groove 21.

[0053] In this embodiment, the shape structure of the limiting groove 21 is adapted to the shape structure of the polarizer accommodated in the material basket 2. The shape structure of the polarizer in this embodiment is illustrated by a rectangle, and the shape structure of the limiting groove 21 should be consistent with the rectangular polarizer shape structure. This allows the blowing pipe 17 and the ion wind rod 18 to move along the circumference direction of the outer edge of the polarizer, and allows the output end of the blowing pipe 17 to be as close as possible to the outer peripheral edge of the polarizer to be taken, so as to accurately blow away the adhesive scale attached to its edge. At the same time, the output end of the ion wind rod 18 can be as close as possible to the polarizer to be taken, so as to effectively remove the static electricity of the polarizer.

[0054] In order to make the contact and pressure between the limit rod 19 and the limit groove 21 smoother, a first roller 20 is installed at the bottom of the limit rod 19 in this embodiment. The limit rod 19 is rolled and squeezed with the inner peripheral groove wall of the limit groove 21 through the first roller 20. The first roller 20 can smoothly transition at each bend in the limit groove 21 to reduce vibration.

[0055] The method for removing polaroids from the basket in this embodiment includes the following steps (this embodiment is illustrated by taking a rectangular polaroid as an example):

[0056] First, use the drive arm 5 to lower the first hanging plate 4, along with the first cylinder 7 and the second hanging plate 6, to the corresponding position above the basket 2. This aligns the output ends of the air blow pipe 17 and the ion wind rod 18 with the outer edge of the stacked polarizer. Use the electric push rod 23 to adjust the electric suction cup 22 to contact the polarizer (the electric suction cup 22 is not activated at this time). The electric suction cup 22 presses and secures the polarizer, preventing the air blow pipe 17 from accidentally blowing the polarizer off the basket 2 during the descaling operation.

[0057] When the electric suction cup 22 touches the polarizer, the output shaft of the drive motor 8 drives the first gear 9, the second gear 10, and the annular rack 13, thereby driving the second cylinder 11 to rotate relative to the first cylinder 7. The second cylinder 11 drives the first connecting rod 14, the second connecting rod 15, the third connecting rod 16, the blowing pipe 17 and the ion wind rod 18 to move around the edge of the polarizer.

[0058] During this period, when the first roller 20 just moves from the front section of the wide side of the limiting groove 21 (corresponding to the wide side of the polarizer) toward the middle of the wide side, the first roller 20 is squeezed by the limiting groove 21 to drive the limiting rod 19 and the second connecting rod 15 to move centripetally, and squeeze the first spring to ensure that the blowing pipe 17 on the third connecting rod 16 can accurately blow away the adhesive scale attached to the edge of the front section of the wide side of the polarizer, and at the same time enable the ion wind rod 18 to effectively remove the static electricity of the polarizer in the corresponding front section area.

[0059] When the first roller 20 moves from the middle position of the wide side to the rear section of the wide side, the first spring in the slide groove pushes the second connecting rod 15 to move centrifugally. At this time, the second connecting rod 15 drives the limiting rod 19 to move synchronously, so that the first roller 20 can always roll and press the wide side of the limiting groove 21, and keep the second connecting rod 15 rolling on the wide side relative to the extended length of the first connecting rod 14, so that the blowing pipe 17 on the third connecting rod 16 can still accurately blow away the glue scale attached to the edge of the rear section of the wide side of the polarizer, and at the same time enable the ion wind rod 18 to effectively remove the static electricity of the polarizer in the rear section area of ​​the wide side.

[0060] When the first roller 20 moves from the wide side to the long side, similar to the movement of the first roller 20 on the wide side, the first spring is compressed and then extended, so that the output end of the blowing tube 17 on the third connecting rod 16 is always close to the corresponding outer peripheral edge of the aligned polarizer, so that the output end of the ion wind rod 18 is always close to the corresponding area of ​​the aligned polarizer. Since the movement of the first roller 20 on the long side of the limiting groove 21 and the elastic change of the first spring are the same as those of the wide side, this embodiment will not elaborate on this.

[0061] After removing the adhesive and static electricity, use the electric suction cup 22 to suck up the polarizer with the adhesive and static electricity removed. Use the electric push rod 23 to adjust the electric suction cup 22 to move up to complete the removal of the polarizer. Then, use the drive arm 5 to move it to the film tearing mechanism for subsequent operations.

[0062] In summary, the advantage of the film taking device of this embodiment is that, according to the arbitrary shape structure of the polarizer to be taken, it is only necessary to select the limiting groove 21 with the same shape and size structure to be installed on the second hanging plate 6. Then, as the output shaft of the drive motor 8 rotates, through the limiting cooperation of the transmission component, the circumferential rotation of the first connecting rod 14 and the second connecting rod 15 can be converted into the third connecting rod 16 and the blowing pipe 17 and the ion wind rod 18 thereon to always keep moving in the direction of the outer edge of the polarizer of the shape structure, so that the output end of the blowing pipe 17 can always be close to and aligned with the outer edge of the polarizer to accurately blow away the adhesive scale attached to the edge of the polarizer, and the output end of the ion wind rod 18 can also be always close to the corresponding area of ​​the polarizer to remove static electricity. It is convenient and practical, and improves production efficiency.

[0063] Example 2

[0064] Please combine Figures 1 to 5 This embodiment is an improvement on Embodiment 1. Positioning rods 24 are provided on both sides of the bottom of the first hanging plate 4, parallel to the third connecting rod 16. Positioning slots 25 are provided on both sides of the open top of the basket 2 for the positioning rods 24 to be inserted into. The positioning rods 24 and the positioning slots 25 facilitate positioning between the sheet removal device and the basket 2 before removing the sheets.

[0065] A rotatable baffle 28 is elastically mounted on one side of the top of the basket 2 near the opening. When the positioning rod 24 is not inserted into the positioning slot 25, the baffle 28 is in a horizontal position with its free end extending into the opening to block the polarizers stacked in the opening and prevent the polarizers in the basket from accidentally falling out of the opening. Specifically:

[0066] A first reel 27 is fixed to the end of baffle 28, away from the opening. A lug is mounted on basket 2. The ends of first reel 27 are inserted into two axial holes (not shown) in the lug. A coil spring connects the ends of first reel 27 to the walls of the axial holes. When the coil spring is not deformed, baffle 28 is horizontal.

[0067] A second roller 26 is fixedly mounted on the first reel 27. When the positioning rod 24 enters the positioning groove 25, the wall of the positioning rod 24 will press and rub the second roller 26 to rotate. The second roller 26 drives the corresponding baffle 28 through the first reel 27 to deflect 90 degrees away from the opening of the material basket 2 until it is vertical. At this time, the free end of the baffle 28 moves out of the opening of the material basket 2 to avoid interfering with the subsequent film retrieval operation.

[0068] In order to better ensure the stability of the material basket 2 when positioning before taking the film, this embodiment elastically inserts rotatable clamping rods 30 on the machine 1 on both sides of the material basket 2. The clamping rod 30 has an L-shaped structure, that is, the clamping rod 30 has a vertical section and a horizontal section. The vertical section is relatively closer to the side of the material basket 2. A flexible clamping pad (not marked) is installed on the side of the vertical section close to the material basket 2 to reduce the damage to the side wall of the material basket 2 caused by rigid contact, and at the same time increase the contact area and static friction between the clamping rod 30 and the material basket 2, so that the clamping is more stable.

[0069] A second reel 32 is secured through the bend of the clamping rod 30. An ear mount is mounted on the machine platform 1. The ends of the second reel 32 are inserted into two axial holes (not shown) in the ear mount. A coil spring connects the ends of the second reel 32 to the walls of the axial holes. When the coil spring is not deformed, the vertical section of the clamping rod 30 is tilted relative to the sidewalls of the basket 2, meaning that the clamping rod 30 does not secure the basket 2.

[0070] In this embodiment, a wire wheel 29 is fixedly mounted on the first reel 27, and a traction rope (not marked) is placed around the wire wheel 29. A fixed pulley 31 is installed on the material basket 2. The free end of the traction rope passes around the fixed pulley 31 to keep it in a tensioned state and is then fixed to the free end of the horizontal section of the clamping rod 30 by a bolt. When the positioning rod 24 is inserted into the positioning groove 25, the wire wheel 29 can follow the first reel 27 to rotate and rewind the traction rope, and pull the free end of the horizontal section of the clamping rod 30 through the traction rope, so that the clamping rod 30 is deflected around the second reel 32 to the material basket 2. The two outer walls of the material basket 2 are effectively clamped and fixed by the vertical sections of the two clamping rods 30, so that the material basket 2 is effectively fixed before taking the film, thereby improving the accuracy of positioning and preventing the material basket 2 from shaking during film taking, which interferes with the film taking operation.

[0071] The above embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and replacements made by technicians in this field on the basis of the present invention fall within the scope of protection required by the present invention.
