The structure of the conveying device of the present invention is shown in fig. 2 to 5.

In the present invention, the X direction and the Y direction are preferably perpendicular to each other.

Specifically, a first bevel gear a123 may be sleeved at one end of the transmission shaft a 121; the X-direction driving unit A11 may include a driving shaft A111, a second bevel gear A112 sleeved on the driving shaft A111, and an X-direction driving member A113; the driving shaft A111 is erected on the conveying rack along the X direction, the second bevel gear A112 is meshed with the first bevel gear A123, and the X-direction driving piece A113 is used for driving the driving shaft A111 to rotate.

Preferably, the driving shaft a111 may be sleeved with a plurality of second bevel gears a112, and the number of the second bevel gears a112 is matched with the number of the X-direction conveying units a12, so that the purpose of driving the plurality of X-direction conveying units a12 (or the plurality of transmission shafts a121) to operate through one driving shaft a111 can be achieved, the structure of the device is simplified, and the floor space of the equipment is reduced.

Further, the X-directional driving component a113 may include a driving motor a1131 and a conveyor belt a1132, the driving motor a1131 is disposed below the driving shaft a111, one end of the conveyor belt a1132 is sleeved on an output end of the driving motor a1131, and the other end is sleeved on the driving shaft a 111. The arrangement mode is favorable for further reducing the space occupation area of the device, so that the structure of the device is more intensive.

Preferably, at least two slip-preventing rings may be fitted over the conveying roller a 122. When the conveyance target of the conveyance device is a workpiece having a small surface friction such as a glass substrate, a slip prevention ring may be fitted over the conveyance roller a122 to increase the friction between the conveyance roller a122 and the workpiece in order to prevent the workpiece from slipping on the surface of the X-direction conveyance mechanism A1.

Further, the Y-direction conveying unit a22 may include a conveying belt a221, a Y-direction driving member, a lifting seat a 222; the conveying belt A221 is installed on the conveying frame through the lifting seat A222, the conveying direction of the conveying belt A221 is parallel to the Y direction, and the Y-direction driving piece is used for driving the conveying belt A221 to run.

When the conveyance target of the conveyance device is a workpiece having a small surface friction such as a glass substrate, a slip prevention ring may be provided on the conveyor a221 to increase the friction between the conveyor a221 and the workpiece in order to prevent the workpiece from slipping on the surface of the Y-direction conveying mechanism A2.

The existing coating modes are mainly two, namely a spraying mode and a roller coating mode.

The spray coating has low requirements on glass substrates, is suitable for glass substrates with different thicknesses and even non-planar glass substrates, but the uniformity of a coating film is difficult to ensure by the spray coating. The roller coating is to use a roller as a carrier of the coating, so that the coating forms a wet film with a certain thickness on the surface of the roller, and then the roller contacts with an object to be coated in the rotating process to coat the coating on the surface of the object to be coated. Compared with a spraying type, the roller coating type can ensure the uniform thickness of a coating film, but the existing roller coating device has the problem of single thickness of the coating film during coating, and cannot meet the requirements of different application occasions on different thicknesses of the coating on the surface of the glass substrate.

Preferably, as shown in fig. 6 to 7, the roll coating device B (the first roll coating device and the second roll coating device may be both structures of the roll coating device B) provided by the present invention includes a roll coating machine frame B5, and a liquid supply mechanism B1, a roll coating mechanism B2, and a roll coating conveying mechanism B3, which are sequentially arranged on a roll coating machine frame B5 from top to bottom; the liquid supply mechanism B1 is used for supplying coating liquid to the roller coating mechanism B2; the roller coating mechanism B2 comprises a coating roller B21, a glue spreader roller B22, a rotary driving mechanism B23 and a spacing adjusting mechanism B24, wherein the coating roller B21 and the glue spreader roller B22 are arranged side by side at intervals, the rotary driving mechanism B23 is used for driving the coating roller B21 and the glue spreader roller B22 to rotate in opposite directions, and the spacing adjusting mechanism B24 is used for adjusting the spacing between the coating roller B21 and the glue spreader roller B22 and the spacing between the coating roller B21 and the roller coating conveying mechanism B3; the roller coating conveying mechanism B3 is positioned below the roller coating mechanism B2 and is used for conveying workpieces to be processed.

The roller coating device B provided by the invention transports the workpiece to be processed by the roller coating conveying mechanism B3, and when the workpiece to be processed is transported to the position below the roller coating mechanism B2, the roller coating mechanism B2 carries out roller coating treatment on the workpiece to be processed. During the roller coating process, coating liquid is supplied to the roller coating mechanism B2 by a liquid supply mechanism B1 positioned above the roller coating mechanism B2. The roller coating mechanism B2 comprises a coating roller B21, a glue spreader roller B22, a rotary driving mechanism B23 and a spacing adjusting mechanism B24. In the coating process, the coating roller B21 and the glue homogenizing roller B22 are driven by the rotary driving mechanism B23 to rotate in opposite directions, air bubbles in the coating liquid can be eliminated by mutual pressing between the coating roller B21 and the glue homogenizing roller B22, and the phenomenon that the air bubbles are brought to the coating roller B21 to cause mark defects on the surface of a workpiece to be processed is prevented. Meanwhile, in order to meet the thickness requirements of surface coatings of workpieces to be processed on different occasions, the distance between the coating roller B21 and the glue spreader roller B22 and the distance between the coating roller B21 and the roller coating conveying mechanism B3 are adjusted by the distance adjusting mechanism B24, so that coating layers with different thicknesses can be formed on the surface of the glass substrate by the roller coating mechanism B2.

As one of the embodiments of the present invention, the diameter of the leveling roller B22 can be made smaller than the diameter of the applicator roller B21. Therefore, the setting of the glue homogenizing roller B22 is facilitated, and the phenomenon that the machining quality of a workpiece to be machined is influenced due to the interference of the glue homogenizing roller B22 and the roller coating conveying mechanism B3 in the glue homogenizing process can be prevented.

As another embodiment of the present invention, the roll coating conveyor mechanism B3 may include a plurality of roll coating conveyor rollers B31 parallel to each other, and a conveyor drive mechanism that drives the roll coating conveyor roller B31 to rotate. In the conveying process, the conveying driving mechanism drives the roller coating conveying roller B31 to rotate, and the workpiece to be machined is driven to move along the conveying direction.

Besides, the roller coating conveying mechanism B3 may be a belt conveyor, a chain conveyor, or the like.

Preferably, the roller coating conveying mechanism B3 may further include a support roller correspondingly disposed just below the coating roller, and the diameter of the support roller is equal to that of the coating roller. The arrangement mode is to enable the coating layer on the surface of the workpiece to be processed to be more uniform in the coating process and avoid the workpiece to be processed from being broken. Since the diameter of the backup roll is equal to that of the application roll B21, the backup roll and the application roll B21 rotate at the same speed during the coating process, and the work piece to be processed can be subjected to the coating process at a stable conveyance speed. Meanwhile, the supporting roll can provide uniform and enough supporting force for the workpiece to be processed, and the workpiece to be processed is prevented from being crushed due to uneven pressure applied by the coating roll B21 or uneven pressure applied by the roller coating conveying roll B31 in the coating process.

As an example of the present invention, the glue roller B22 may be a metal roller and the applicator roller B21 may be a rubber roller. Since the metal roller and the rubber roller have different viscosities with respect to the coating liquid, the coating liquid can adhere to the coating roller B21, but not to the leveling roller B22. During the coating process, when the coating liquid passes through the distance between the coating roller B21 and the glue homogenizing roller B22, the thickness of the glue liquid is convenient to control.

Further, the liquid supply mechanism B1 may include a liquid storage B11 and a liquid guide B12 communicating with the bottom of the liquid storage B11, and the discharge end of the liquid guide B12 is disposed above the gap between the coating roller and the glue spreader roller B22.

Wherein the first vertical adjusting member and the first horizontal adjusting member may be driving cylinders. The distances between the coating roller B21 and the roller coating conveying mechanism B3 and between the coating roller B21 and the roller homogenizing roller B22 can be adjusted by controlling the lifting and/or horizontal movement of the coating roller B21; and further adjusting the thickness of the coating layer on the surface of the workpiece to be processed.

Preferably, the spacing adjustment mechanism B24 may further include a second vertical adjustment member and a second horizontal adjustment member connected to each other, the second vertical adjustment member controls the leveling roller B22 to perform a lifting motion, and the second horizontal adjustment member controls the leveling roller B22 to perform a horizontal motion. Wherein the second vertical adjusting member and the second horizontal adjusting member may be driving cylinders. By controlling the lifting and/or horizontal movement of the spreader roller B22, the distance between the spreader roller B22 and the applicator roller B21 can be adjusted, and the thickness of the surface coating of the workpiece to be processed can be adjusted.

In addition, the distance adjusting mechanism B24 controls the coating roller B21 and the glue spreader roller B22 to move relatively at the same time, so that the distance adjusting process between the coating roller B21 and the glue spreader roller B22 can be accelerated, and the processing efficiency is improved.

As an embodiment of the present invention, the roll coating mechanism B2 may further include a pressure adjusting unit, the pressure adjusting unit includes a pressure sensor provided on the coating roll B21, and the pressure sensor is connected to the spacing adjusting mechanism B24 through a spacing control circuit. During operation, the pressure sensor senses the pressure between applicator roll B21 and spreader roll B22, and/or between applicator roll B21 and the part to be processed. Different coating layer thicknesses and different pressures between the corresponding coating roller B21, the corresponding glue spreader roller B22 and the corresponding coating roller B21 and the workpiece to be processed in the coating process, so that the pressure in the coating process is detected by the pressure sensor, and the judgment of whether the coating layer thickness on the surface of the workpiece to be processed meets the requirement or not is facilitated. When the pressure sensor detects that the pressure value is within the preset range, the coating process is normally carried out; if the pressure sensor detects that the pressure value is not within the preset range, the distance adjusting mechanism B24 is controlled through the distance control circuit, and then the distance between the coating roller B21 and the roller coating conveying mechanism B3 and the distance between the coating roller B21 and the glue homogenizing roller B22 are adjusted, so that the control and adjustment of the thickness of the coating layer on the surface of the workpiece to be processed are realized.

Preferably, the bottom of the roller coating machine frame B5 is also provided with a roller B4. The roller B4 is favorable for moving the roller coating device, and is convenient to carry.

In the prior art, when plates such as glass, steel plates and stone plates are processed, the plates are often required to be taken and transported manually or by a lifting appliance, and the taking and transporting mode is low in production efficiency, low in safety, easy to damage the plates and the like.

At present, although some manufacturers on the market use vacuum chucks for transporting plates, the vacuum chucks have a problem that the space between the vacuum chucks is fixed and cannot be adjusted. In the process of taking, transporting and placing materials, when the size of a product is not matched with the coverage area of the vacuum chuck, the vacuum chuck with different specifications must be equipped to take and place the product simultaneously so as to meet the shipping requirement of the product, and the use convenience of the vacuum chuck is greatly influenced.

The existing vacuum suction cup D32 is only suitable for the condition that a plurality of suction heads work simultaneously and can not meet the requirement that only part of the suction heads need to work under part of working conditions.

To solve this problem, a vacuum logic valve D33 may be provided on each vacuum cup D32, and when the cup D32 sucks the product, the vacuum logic valve D33 is opened to generate vacuum; for the suction cup D32 which does not suck the product, because the corresponding vacuum logic valve D33 is in a closed state, the vacuum leakage can not be caused, and the suction vacuum degree of other suction cups D32 is influenced; therefore, the normal work of a part of the suckers D32 needing to work in the material taking device can be ensured, and the requirement that the material taking device absorbs plane objects with any shapes and specifications is met, so that the material taking device provided by the invention meets the universality within a certain size range.

In the process of processing a glass substrate, in order to prevent the surface of the glass substrate from being scratched, a protective film is generally adhered on the glass substrate; therefore, the surface of the glass substrate can be prevented from being scratched, and the glass substrate can be protected in the pretreatment process. However, the protective film needs to be removed during subsequent processing.

At present, the treatment to glass substrate surface film all adopts artifical manual tearing to remove, can not realize the automation of protection film and peels off, and whole operation process automation degree is low, wastes time and energy, and the protection film strips after peeling off and retrieves untimely, causes the material easily to pile up, influences subsequent manufacturing procedure greatly.

Therefore, how to provide a film tearing device with high automation degree and high working efficiency becomes a technical problem to be solved urgently by the technical personnel in the field.

In order to solve the problem, the invention also provides a film tearing device E which can realize automatic peeling of the protective film, and has the advantages of simple structure, high automation degree, time and labor saving and high working efficiency.

Specifically, as shown in fig. 15, the film tearing device E provided by the present invention includes a film tearing frame E1, and a film tearing conveying mechanism E2 disposed on the film tearing frame E1; the film tearing conveying mechanism E2 is used for conveying workpieces; the film rolling barrel E3, the film tearing mechanism E4 and the material receiving mechanism E5 are installed on the film tearing rack E1 and are sequentially arranged along the workpiece conveying direction of the film tearing conveying mechanism E2; the winding barrel E3 is used for releasing the adhesive tape; the film tearing mechanism E4 comprises a pressing roller E41 and a tearing starting roller E42, the pressing roller E41 is used for pressing the adhesive tape and the workpiece together, the tearing starting roller E42 is used for guiding the adhesive tape adhered with the protective film away from the surface of the workpiece, and the diameter of the tearing starting roller E42 is smaller than that of the pressing roller E41; the adhesive tape starts from a winding barrel E3, sequentially winds through a pressing roller E41 and a tearing roller E42 and finally is collected into a material receiving mechanism E5; the receiving mechanism E5 is used for receiving the adhesive tape.

The film tearing device provided by the invention comprises a winding barrel E3, a film tearing mechanism E4, a material receiving mechanism E5 and a film tearing and conveying mechanism E2. The winding drum E3 is used for releasing adhesive tapes, the film tearing mechanism E4 comprises a pressing roller E41 and a tearing starting roller E42, and the adhesive tapes for adhering the protective films sequentially wind the pressing roller E41, the tearing starting roller E42 and the receiving mechanism E5 from the winding drum E3. In the film tearing process, under the conveying action of a film tearing conveying mechanism E2, workpieces sequentially pass through a space between a pressing roller E41 and a film tearing conveying mechanism E2 and a space between a tearing roller E42 and a film tearing conveying mechanism E2; the pressing roller E41 is used for pressing the adhesive tape on the surface of the workpiece, so that the adhesive tape is attached to the surface of the workpiece, and the adhesive tape is further attached to the protective film on the surface of the workpiece; the function of the tearing roller E42 is to guide the adhesive tape adhered with the protective film away from the surface of the workpiece, so that the protective film is separated from the surface of the workpiece. In order to ensure good film tearing effect, the diameter of the tearing-starting roller E42 is required to be smaller than that of the pressing roller E41, because the smaller the diameter is, the larger the curvature of the roller is, and the larger the bending degree is; in the pressing process, in order to ensure the tightness of the adhesion between the adhesive tape and the surface of the workpiece, the curvature of the pressing roller E41 is small, and the bending degree is small. After the pressing process is completed, the protective film needs to be torn off the surface of the workpiece by using the adhesive tape, and the adhesive tape sequentially winds around the pressing roller E41 and the tearing start roller E42, so that the diameter of the tearing start roller E42 is smaller than that of the pressing roller E41, the extending direction of the adhesive tape is matched with the curvature changing direction of the tearing start roller E42, and a good peeling effect can be achieved between the protective film and the workpiece. This is also because the work of the present invention is a glass substrate, which is thin and large in size, and if the turning angle of the tape is small, the glass substrate and the protective film are brought away from the surface of the tear film transfer mechanism E2 by the tape. Therefore, the diameter of the tearing-starting roller E42 is smaller than that of the pressing roller E41, the film tearing mechanism E4 can achieve a good film tearing effect, the rejection rate is low, and the working efficiency is high.

As one embodiment of the present invention, the pressing roller E41 may be arranged on the film tearing frame E1 in a liftable manner. Thus, when the film tearing operation is required to be carried out on the workpiece, the pressing roller E41 moves downwards to press the adhesive tape and the surface of the workpiece together; after the film tearing operation is completed, the pressing roller E41 is lifted, and movement away from the film tearing conveying mechanism E2 occurs.

Preferably, the two ends of the stitching roller E41 can be connected with a lifting frame E43, and the lifting frame E43 is fixed on the film tearing frame E1 through a lifting driving piece E44. The stitching roller E41 is driven by the lifting driving piece E44 to perform lifting movement.

Preferably, the winding barrel E3 in the present invention is further provided with a locking structure for limiting the rotation of the winding barrel E3, so as to avoid the winding barrel E3 from rotating when the film tearing device is not in operation to tear the film, which leads to the scattering of the adhesive tape.

Preferably, film tearing mechanism E4 may further include a first sensor E45 and a first control circuit, wherein first sensor E45 is used for detecting the workpiece on film tearing conveying mechanism E2, and first sensor E45 is connected to lifting drive member E44 through the first control circuit.

In the working process, when the first sensor E45 detects that a workpiece is conveyed on the film tearing and conveying mechanism E2, the first sensor E45 transmits a signal to the first control circuit, the first control circuit controls the lifting driving piece E44 to drive the pressing roller E41 to move downwards, so that the adhesive tape is attached to the surface of the workpiece, and the film tearing process is started; when the first sensor E45 detects that no workpiece exists on the film tearing and conveying mechanism E2, the first sensor E45 transmits a signal to the first control circuit, and the lifting driving piece E44 is controlled by the first control circuit to drive the pressing roller E41 to move upwards and is far away from the film tearing and conveying mechanism E2. The setting of first inductor E45 can improve the accuracy and the validity of dyestripping device dyestripping, promptly, only when the inductor senses the existence of work piece, just can control stitching roller E41 and carry out the pressfitting process, and then carry out the dyestripping process, reduces the emergence of invalid action.

Preferably, the first sensor E45 may be further connected to the material receiving mechanism E5 through a third control circuit, and when the first sensor E45 senses that a workpiece is transported on the film tearing and conveying mechanism E2, the first sensor E45 transmits a signal to the third control circuit, and the third control circuit controls the material receiving mechanism E5 to start a material receiving movement, so as to drive the adhesive tape to move around each roller, and to start a film tearing process in cooperation with a descending movement of the pressing roller E41. Similarly, when the first sensor E45 senses that no workpiece exists on the film tearing and conveying mechanism E2, the first sensor E45 transmits a signal to the third control circuit, the third control circuit controls the material receiving mechanism E5 to stop receiving material movement, and the film tearing process is suspended in cooperation with the rising movement of the pressing roller E41.

The arrangement mode can effectively save the use of the adhesive tape. That is, the film tearing apparatus starts the film tearing operation only when there is a workpiece on the film tearing conveyance mechanism E2, otherwise the film tearing process is suspended.

As one of the embodiments of the present invention, the receiving mechanism E5 may include a guide E51 and a receiver E52, the guide E51 is used to guide the adhesive tape wound from the tearing-off roller E42 to the receiver E52, and the receiver E52 is used to recover the adhesive tape.
