Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
As shown in fig. 1 and fig. 2a to 2c, in one aspect, the embodiment of the invention provides a glue spreading device 01, where the glue spreading device 01 includes a base 1, and a substrate 2 to be spread is placed on the base 1; the gluing device 01 further comprises: the guide mechanism 3, the connecting mechanism 4 and the gluing mechanism 5 are all arranged above the base station 1;
the gluing mechanism 5 is connected with the connecting mechanism 4 in a sliding manner, and the connecting mechanism 4 is configured to drive the gluing mechanism 5 to slide along the guiding direction of the guiding mechanism 3;
the gluing mechanism 5 comprises a glue injection head 511;
in the process that the glue applying mechanism 5 slides along the guiding direction, a preset distance is kept between the glue injection head 511 and the surface of the substrate 2.
It should be noted that the glue spreading device provided in the first embodiment of the present invention can be used for spreading glue on a wavy substrate, and here, the glue spreading device is not limited to spreading glue on a wavy substrate, but also can be used for spreading glue on non-planar substrates such as a continuous trapezoidal substrate (i.e., the cross section of the substrate is trapezoidal along the vertical direction of the substrate plate surface) and a continuous V-shaped substrate (i.e., the cross section of the substrate is V-shaped along the vertical direction of the substrate plate surface).
Secondly, referring to fig. 1, for the convenience of the following description and understanding, an XYZ rectangular coordinate system is established in a space including the base 1, wherein the base 1 has a table 11, an X direction is perpendicular to the guide direction and parallel to the table 11, a Y direction is parallel to the guide direction and the table 11, and a Z direction is perpendicular to the table 11.
Based on this, in the glue spreading device 01 provided in the embodiment of the present invention, the glue spreading mechanism 5 slides along the guiding direction of the guiding mechanism 3, and meanwhile, a preset distance is kept between the glue injection head 511 of the glue spreading mechanism 5 and the surface of the substrate 2, so as to adapt to the shape of the surface of the substrate or control the glue spreading amount at different positions of the surface of the substrate.
For example, when the preset distance is set to be a constant value, the motion track of the glue injection head 511 of the glue applying mechanism 5 and the surface of the substrate 2 are matched with each other, so that the glue applying mechanism 5 can coat a uniform glue line matched with the surface of the substrate 2 on the surface of the substrate 2. For example, when the substrate 2 is a wavy substrate 2 as shown in fig. 3, the motion trajectory of the glue injection head 511 of the glue applying mechanism 5 above the surface of the substrate 2 is a wavy curve matched with the surface of the substrate 2, so that the glue applying mechanism 5 can apply a wavy curve glue solution B matched with the surface of the substrate 2 on the surface of the substrate 2.
The preset distance may also be set to be a non-constant value, for example, when the glue spreading amount needs to be increased at a certain point or a certain section on the substrate 2, and the glue injection head 511 moves to the point or the section, more glue solution can flow out of the glue bottle and be coated on the point or the section by adjusting the preset distance, so that the glue spreading apparatus 01 provided by the embodiment of the present invention can control the glue spreading amount at different positions on the surface of the substrate 2.
Referring to fig. 3, the glue spreading device 01 according to the embodiment of the present invention is applicable to a glue spreading process for a wavy substrate 2 and a glue spreading for a curved substrate. And the guide mechanism 3 can drive the gluing mechanism 5 to reciprocate along the guide directionSo that the gluing mechanism 5 can perform the gluing on the surface of the substrate 2 by y1To y2Direction, by y2To y1The direction makes a round trip to glue many times, consequently, rubber coating device 01 can also realize making a round trip to glue many times to base plate 2 to improve work efficiency, practice thrift the rubber coating time, improve output.
Here, y1And y2For example, the two ends of the wavy edge of the wavy substrate 2 may be provided.
Therefore, the gluing device 01 provided by the embodiment of the invention is a gluing device particularly suitable for gluing a curved substrate, and fills up the technical blank in the current market.
Further, in order to keep a preset distance between the glue injection head 511 and the surface of the substrate 2, the glue coating apparatus 01 includes a preset trajectory control mechanism for presetting a motion trajectory of the glue injection head 511 above the surface of the substrate 2. The specific structure of the preset trajectory control mechanism may follow the relevant design, which is not limited in the embodiment of the present invention. For example, the preset trajectory control mechanism may include: a control unit and a drive unit; the control unit is used for outputting a control instruction, and the driving unit is used for controlling the glue injection head 511 of the glue injection mechanism 5 to move along a preset track under the control of the received control instruction.
For example, when a uniform glue line is required to be coated on the surface of the substrate 2, the preset trajectory control mechanism sets the distance between the glue injection head 511 and the surface of the substrate 2 to be a constant value, that is, the motion trajectory of the glue injection head 511 is preset to be a wavy curve matching with the surface of the substrate 2.
When the glue spreading amount of a certain point or a certain section on the substrate 2 needs to be increased, the preset track control mechanism increases the preset distance between the glue injection head 511 and the point or the section. When the glue injection head 511 moves to the point or above the section, more glue solution can flow out of the glue bottle and be coated on the point or the section.
Referring to fig. 1 and fig. 2a to 2c, the specific structure of each mechanism will be described separately below:
specifically, referring to fig. 1 and 2a, the guide mechanism 3 includes: a support frame 31 provided on the base 1, and a guide rail 32 provided on the support frame 31. The connecting mechanism 4 is disposed on the guide rail 32, and the extending direction of the guide rail 32 is the guiding direction. The connecting mechanism 4 can reciprocate along the guide rail 32, so as to drive the gluing mechanism 5 to reciprocate in the extending direction of the guide rail 32.
Further, as shown in fig. 4, the guide rail 32 may be a screw 32. The connecting mechanism 4 is sleeved on the screw rod 32. The gluing device 01 is provided with a driving mechanism, the driving mechanism drives the screw rod 32 to rotate, the connecting mechanism 4 is driven to move along the screw rod 32, and therefore the gluing mechanism 5 is driven to move in the extending direction of the screw rod 32.
By way of example, the drive mechanism may be an electric motor. Compare in the manual mode that makes coupling mechanism 4 slip, the motor operation is quick, consequently can further improve rubber coating device 01's rubber coating efficiency, and the motor can drive coupling mechanism 4 and slide on lead screw 32 at the uniform velocity, avoids the injecting glue head 511 to differ too much in the different positions dwell time on base plate 2 surface for the glue solution of beating gluey mechanism 5 coating on base plate 2 is more even.
Referring to fig. 4, since the threads of the screw rod 32 are uniformly arranged, when the screw rod 32 rotates, the connecting mechanism 4 can be driven to do uniform motion along the screw rod 32, so as to drive the gluing mechanism 5 to do uniform motion in the Y direction, and thus the glue solution coated on the substrate 2 by the gluing mechanism 5 is more uniform.
As shown with reference to fig. 2b, the connection mechanism 4 may particularly comprise a moving member 41. The moving member 41 is slidably connected to the guide rail 32, so that the moving member 41 can slide back and forth along the guide rail 32. The gluing mechanism 5 is slidably connected to the moving member 41 so that the gluing mechanism 5 can slide back and forth in the Z direction.
Further, the moving member 41 may be divided into two parts, namely a first connecting member 411 and a second connecting member 412 slidably connected with the first connecting member 411; the first connecting member 411 is slidably connected to the guide rail 32, and the second connecting member 412 is slidably connected to the gluing mechanism 5. This makes it easy to install and maintain the moving member 41, and it is also possible to reduce the difficulty of processing the moving member 41.
Further, the connection mechanism 4 further includes: the lifting control member 42 is disposed on the first connecting member 411, and the lifting control member 42 is configured to drive the second connecting member 412 to reciprocate along a direction perpendicular to the guiding direction, i.e., the Z direction in fig. 1; wherein, the output end of the lifting control member 42 is fixedly connected with the second connecting member 412.
Based on the above structure, as shown in fig. 1, fig. 2a to fig. 2c and fig. 3, when the gluing mechanism 5 moves to the edge 2c of the substrate 2, after the gluing is completed, the lifting control member 42 drives the second connecting member 412 to move upward along the Z direction, and since the gluing mechanism 5 is connected to the second connecting member 412, the second connecting member 412 drives the gluing mechanism 5 to move upward along the Z direction, so that the gluing mechanism 5 is separated from the surface of the substrate 2, i.e., separated from the surface of the substrate 2, and a certain distance is left between the gluing mechanism 5 and the substrate 2, thereby facilitating the replacement of the substrate 2 to be glued. When the glue applying mechanism 5 starts to apply glue to the substrate 2, the lifting control member 42 drives the second connecting member 412 to move downward along the Z direction, so that the glue applying mechanism 5 falls back to the surface of the substrate 2 until contacting the surface of the substrate 2 to start applying glue to the substrate 2.
The above-described structure allows the gluing device 01 to control the gluing device 5 to contact the substrate 2 at the start of gluing and to separate from the substrate 2 at the end of gluing.
Specifically, referring to fig. 2b, the lift control member 42 includes: a lifting member 421 and a third connecting member 422; the lifting member 421 is fixed on the first connecting member 411, the driving end of the lifting member 421 is fixedly connected to the third connecting member 422, and the third connecting member 422 is fixedly connected to the second connecting member 412. The lifting member 421 drives the third connecting member 422 to move up and down in a direction perpendicular to the guide rail 32, and the third connecting member 422 drives the second connecting member 412 to move up and down in a direction perpendicular to the guide rail 32, so as to drive the gluing mechanism 5 to move up and down in a direction perpendicular to the guide rail 32, so that the gluing mechanism 5 can contact with the substrate 2 at the beginning of gluing and be separated from the substrate 2 at the end of gluing.
Specifically, referring to fig. 2b, the lifting member 421 includes: a power take-off 421a, a support bar 421b, a first guide bar 421c, and a first slider 421d for reciprocating along the first guide bar 421 c;
as shown in fig. 1 and fig. 2, the power output member 421a is fixed on the first connecting member 411, and the power output member 421a is used for controlling the supporting rod 421b to extend and retract along a direction perpendicular to the table 11; one end of the support rod 421b close to the table 11 is connected with the power output member 421a, and one end of the support rod 421b far from the table 11 is fixedly connected with the third connecting member 422; the first sliding block 421d is fixed to the third connecting member 422, the second connecting member 412 is fixed to the first sliding block 421d, and the first guide strip 421c is fixed to the power take-off member 421 a.
Here, in fig. 2b, only two support rods 421b are taken as an example for illustration, which is not limited in the embodiment of the present invention, and the number of the support rods 421b may be only one or more than two, so as to stably support the third connecting member 422 to move up and down along the direction perpendicular to the table top 11.
Further, for convenience of installation and maintenance, the lifting member 421 further includes a fixing mounting plate 421e, and the lifting member 421 is fixedly mounted on the first connecting member 411 through the fixing mounting plate 421e, that is, the fixing mounting plate 421e is fixedly connected to the first connecting member 411.
Specifically, the lifting member 421 may be a pneumatic lifting member or a hydraulic lifting member.
The pneumatic lifting piece is simple and light in structure, convenient to install and maintain and high in safety coefficient in the using process compared with the hydraulic lifting piece, so that the lifting piece 421 is preferably the pneumatic lifting piece.
Specifically, referring to fig. 2c, the glue applying mechanism 5 includes: the contact piece 52 is arranged on the glue injection piece 51, and the glue injection piece 51 is connected with the connecting mechanism 4 in a sliding manner; the glue injection head 511 is arranged on the glue injection piece 51;
the contact 52 is for contacting the substrate 2, and the contact 52 is configured to keep a distance between the glue injection head 511 and the substrate 2 uniform.
Since the contact member 52 of the gluing mechanism 5 is in contact with the substrate 2 during the movement of the gluing mechanism 5 in the Y direction, the motion trajectory of the contact member 52 on the surface of the substrate 2 is a wave-like curve matched with the surface of the substrate 2. Since the contact member 52 is disposed on the glue injection member 51 and the contact member 52 is disposed so that the distance between the glue injection head 511 and the substrate 2 is kept consistent, the movement locus of the glue injection head 511 of the glue injection member 51 on the surface of the substrate 2 is a wavy curve matched with the surface of the substrate 2. Thus, referring to fig. 4, the glue applying mechanism 5 can apply a wavy curved glue solution B on the surface of the substrate 2, wherein the wavy curved glue solution B matches with the surface of the substrate 2. For example, when the contact 52 moves to the trough 2a of the substrate 2, the glue injection head 511 correspondingly moves to above the trough 2a of the substrate 2, so that the glue applying mechanism 5 applies the glue solution to the trough 2a of the substrate 2; when the contact member 52 moves to the peak 2b of the substrate 2, the glue injection head 511 correspondingly moves to above the peak 2b of the substrate 2, so that the glue applying mechanism 5 applies the glue solution to the peak 2b of the substrate 2.
As shown in fig. 5, the distance between the glue injection head 511 and the mesa 11 (denoted by h in fig. 5)1) Greater than the minimum distance (denoted h in fig. 3) between the contact 52 and the mesa 112) (ii) a Therefore, a gap is formed between the glue injection head 511 and the substrate 2 all the time, so that the glue solution can flow out from the glue injection head 511 and be coated on the surface of the substrate 2.
The minimum distance between the contact 52 and the mesa 11 is a distance between a point of the contact 52 closest to the mesa 11 and the mesa 11.
Further, referring to fig. 2c, the glue injection member 51 includes: the glue injection bracket 512 and a sliding part 513 arranged on the glue injection bracket 512; wherein,
the contact member 52 is disposed on the glue injection support 512, the sliding member 513 is perpendicular to the guiding direction, and the connecting mechanism 4 is disposed with a guiding member 514 engaged with the sliding member 513.
Here, fig. 2c only illustrates the guide 514 and the sliding part 513 as the sliding groove 514 and the sliding strip 513, respectively, which is not limited to this embodiment of the present invention, and the guide 514 and the sliding part 513 may be a guide pillar, a guide sleeve, etc., for example, as long as the two structures can slide relatively.
Because the sliding member 513 is perpendicular to the guiding direction, and the sliding member 513 and the contact member 52 are fixed on the glue injection bracket 512, the glue injection bracket 512 can reciprocate along the direction perpendicular to the guiding direction, so as to drive the glue bottle 515 and the glue injection head 511 mounted thereon to reciprocate along the direction perpendicular to the guiding direction, and the distance between the glue injection head 511 and the substrate 2 is kept consistent.
Further, in order to restrict the sliding member 513 from being disengaged from the guide member 514, a stopper 513a is provided at an end of the sliding member 513 away from the base 2.
For example, the glue injection bracket 512 may be the glue injection bracket 512 shown in fig. 6.
Referring to fig. 6, the glue injection bracket 512 has a supporting portion 512a and a circumferential fixing portion 512b, when the glue bottle 515 is fixed on the glue injection bracket 512, the supporting portion 512a plays a role of supporting the glue bottle 515 upwards, and the circumferential fixing portion 512b plays a role of keeping the glue bottle 515 in a vertical state all the time, so as to prevent the glue bottle 515 from swinging left and right or back and forth, which affects the accuracy of the glue application position.
Here, please refer to the related art for a specific fixing manner of the glue injection bracket 512 for fixing the glue bottle 515, which is not described in detail in the embodiments of the present invention.
Further, referring to fig. 2c, since the contact 52 is in contact with the substrate 2 during the moving process, the substrate 2 may be subjected to a certain friction force, so as to easily damage the substrate 2, and therefore, in order to reduce the damage, the contact 52 specifically includes: the roller bracket 521 and the roller 522 arranged at one end of the roller bracket 521, the other end of the roller bracket 521 is arranged on the glue injection bracket 512, and the roller 522 is used for contacting the substrate 2 and rolling along the surface of the substrate 2. The roller 522 is in rolling contact with the surface of the substrate 2 to generate a rolling friction force, which greatly reduces the friction force applied to the substrate compared with a sliding friction force, thereby reducing the damage of the contact member 52 to the substrate 2.
In order to further reduce the damage of the contact member 52 to the substrate 2 during the movement, the roller 522 may be an elastic roller.
Further, referring to fig. 2c, the glue applying apparatus 01 further includes: an air tube 9 and a pneumatic control (not shown in fig. 2 c) connected to the glue bottle 515 through the air tube 9; wherein the pneumatic control element is used for controlling the glue discharging amount of the glue bottle 515. Therefore, the glue discharging of the glue bottle 515 is fast and uniform, and the glue discharging amount can be adjusted at will.
Further, the material of the glue injection head 511 may be metal. The injecting glue head of metal material is for disposable plastics injecting glue head, and is fixed more firm, and the dead weight is bigger with the bottleneck of gluing the bottle for gluing the in-process and can not the horizontal hunting for the rubber coating position is more accurate.
For example, the glue injection head 511 may be an aluminum alloy glue injection head.
Further, in order to realize the quick glue changing operation and reduce the glue changing times, the glue bottle 515 can be selected to be customized and batch produced, the glue barrel is simple in structure and large in capacity, the time for changing the glue bottle 515 in large quantity can be saved, the glue filling process is reduced, and the working efficiency is further improved.

Further, as shown in fig. 7, since the substrate 2 is in contact with the positioning contacts 724 during the positioning process and is subjected to a certain pressing force, in order to protect the substrate 2 from being damaged during the positioning process, the positioning contacts 724 may further be provided with substrate contacts 728 made of an elastic material (e.g., rubber, sponge, etc.).

At least one first positioning member 71 is arranged on the outer side of the plate surface of one of the two substrate supporting plates 81, and a second positioning member 72 corresponding to the first positioning member 71 is arranged on the outer side of the plate surface of the other one of the two substrate supporting plates 81;
for example, as shown in fig. 1, two sides of two substrate supporting plates 81 are respectively provided with a first positioning member 71 and a second positioning member 72, which can fix the substrate 2 from the Y direction, so that the substrate does not generate Y-direction displacement during the gluing process.
It should be noted that, referring to fig. 1, two ends of the substrate supporting plate 81 respectively refer to one end of the substrate supporting plate 81 close to the guide mechanism 3 and one end of the substrate supporting plate 81 far from the guide mechanism 3;
the plate-surface outer sides of the two substrate supporting plates 81 refer to both sides of a surface of the two substrate supporting plates 81 away from each other.
The overall working steps and working principle of the above gluing device are summarized as follows with reference to fig. 1:
step S1, placing the substrate 2 on the substrate base 8, and fixing the substrate 2 on the substrate base 8 by the positioning mechanism 7;
step S2, dropping the gluing mechanism 5 over the surface of the substrate 2 by the lifting control member 42, and bringing the roller 54 into contact with the surface of the substrate 2;
step S3, the guide mechanism 3 drives the gluing mechanism 5 to move in the Y direction through the connecting mechanism 4; in the process that the gluing mechanism 5 moves in the Y direction, the roller 54 rolls on the surface of the substrate 2, so that the gluing mechanism 5 moves up and down along with the fluctuation of the surface of the substrate 2, and in the process, the gluing mechanism 5 coats glue solution on the surface of the substrate 2;
in step S4, the gluing mechanism 5 is lifted by the lifting control member 42 so that the roller 54 is away from the surface of the substrate 2.
In another aspect, the embodiment of the present invention further provides a glue spreading system, which includes the above glue spreading apparatus.
Further, referring to fig. 1 and 8, the glue spreading system according to the embodiment of the present invention further includes: a shielding plate 10 arranged on one surface of the substrate 2 far away from the base station 1; the shielding plate 10 exposes the area to be coated on the substrate 2.
Specifically, as shown in fig. 4 and 8, the shielding plate 10 has a shape matching with the substrate 2 to be glued, including a correspondingly matched arc surface and the like.
As shown in fig. 9, the shielding plate 10 is covered on the substrate 2 to be glued, the area to be glued on the substrate 2 is exposed, and the gluing mechanism 5 coats the glue solution on the substrate 2 along the edge 10a of the shielding plate 10, so that the gluing position is more accurate.

After the gluing device 01 finishes gluing to the substrate 2, the adhesive tape 11 can be pasted along the edge 10a of the baffle plate 10 in the area where the glue solution is coated on the surface of the substrate 2, so that the adhesive tape 11 is aligned accurately with the area where the glue solution is coated, the installation is faster and more accurate, and the working efficiency is further improved.
It is understood that, when the shielding plate 10 is covered on the substrate 2 to be coated, the roller 54 contacts the surface of the shielding plate 10, i.e., the roller 54 rolls on the surface of the shielding plate 10, during the coating of the substrate 2 by the coating device 01.
