[0002] The high-precision single-piece glue laminating machines currently on the market only have a single-row arrangement, and only laminating one piece of material at a time, which greatly limits the efficiency of high-precision glue laminating. Utility Model Content

[0003] The utility model provides a multi-station gluing mechanism and a gluing machine, which are used to solve the technical problem of low efficiency that only one piece of material can be glued at a time for a single row of single material.

[0004] The technical solution adopted by the utility model is:

[0005] A multi-station glue sticking mechanism comprises a workpiece conveying member, a glue discharging structure and a glue taking structure; the workpiece conveying member is provided with a glue sticking station, a glue discharging structure is provided on the outer side of the glue sticking station, the glue discharging structure is provided with at least two glue-to-be-taken stations at positions corresponding to the glue sticking stations, the glue taking structure is provided with a horizontal multi-joint manipulator and a lifting and placing glue picking component, the rotating lifting part of the horizontal multi-joint manipulator is provided with at least two lifting and placing glue picking components, and the lifting and placing glue picking components correspond to the glue-to-be-taken stations one by one; the lifting and placing glue picking component which obtains double-sided adhesive tapes on at least two glue-to-be-taken stations at one time switches between the glue-to-be-taken station and the glue sticking station under the drive of the horizontal multi-joint manipulator. The workpiece conveyor adopts a conveyor belt. During the conveying, the workpieces to be glued can be conveyed side by side, or two in a row, and at least two materials to be glued can be conveyed at a time. That is to say, the workpiece conveyor will stop when it conveys the conveyed materials to be glued to the gluing station. At this time, there will be at least two materials to be glued at the gluing station. The horizontal multi-joint manipulator rotates and lifts to control the lifting and placing glue assembly to obtain the double-sided tape at the gluing station and transfer it to the gluing station for gluing. After the gluing is completed, the workpiece conveyor conveys the glued workpiece out of the gluing station, and the new workpiece to be glued is transferred to the gluing station to wait for the next gluing. The horizontal multi-joint manipulator uses a Yamaha horizontal multi-joint manipulator.

[0006] As a preferred solution of the utility model, a glue outlet structure is respectively arranged on the two outer sides of the glue sticking station, and the two glue outlet structures are standby for each other. Initially, one of the glue outlet structures is used first, starting with the left side according to the setting habit. When the double-sided tape on the left side is used up, the other glue outlet structure, that is, the glue outlet structure on the right side, is used. In this way, uninterrupted glue sticking can be avoided and shutdown due to lack of double-sided tape can be avoided.

[0007] As a preferred solution of the utility model, the setting direction of the workpiece on the glue sticking station is perpendicular to the setting direction of the double-sided tape to be taken on the glue taking station.

[0008] As a preferred solution of the utility model, a glue picking bracket is installed on the rotating lifting part of the horizontal multi-joint manipulator, and a lifting glue picking and placing component is installed on both sides of the glue picking bracket. The setting of the glue picking bracket can better install the lifting glue picking and placing component, so that it can more accurately correspond to the glue picking station, and the two do not affect each other.

[0009] As a preferred solution of the utility model, each lifting and placing glue picking assembly includes a lifting power part, a glue picking base plate and a glue picking adsorption plate. The lifting power part is installed on the glue picking bracket, the telescopic part of the lifting power part is connected to the glue picking base plate, the glue picking base plate is provided with a negative pressure channel, the glue picking adsorption plate is fixed on the lower end surface of the glue picking base plate, the glue picking adsorption plate is provided with an air cavity, and through adsorption air holes are arranged at the bottom of the air cavity, and the adsorption air holes are connected to the negative pressure channel through the air cavity. The vacuum equipment is connected to the negative pressure channel. After the lifting power part descends to make the glue taking substrate contact with the double-sided adhesive to be taken, the gas enters the air cavity from the adsorption hole and then enters the vacuum equipment from the negative pressure channel to form a negative pressure between the adsorption hole and the double-sided adhesive to be taken. The double-sided adhesive to be taken is adsorbed, and then the lifting power part rises and is transferred to the glue sticking station under the drive of the horizontal multi-joint manipulator. The horizontal multi-joint manipulator descends to bring the lifting and placing glue assembly close to the workpiece to be glued. The lifting power part descends to make the glue taking adsorption plate adsorb the double-sided adhesive and press the workpiece to be glued downward. The vacuum equipment stops moving, and the double-sided adhesive is separated from the glue taking adsorption plate and adhered to the workpiece to be glued. At least two pieces of double-sided adhesive are adsorbed each time and the workpieces to be glued that are transported side by side are glued to improve the glue sticking efficiency.

[0010] As a preferred solution of the utility model, the two lifting and placing glue components are not synchronized. In a glue picking or gluing action, one lifting and placing glue component picks up or puts glue first, and then the other lifting and placing glue component picks up or puts glue. That is to say, when completing a process action, there will be a height difference between the two lifting and placing glue components.

[0011] Of course, you can also adsorb or release glue synchronously, and the specific synchronization or asynchronous setting is based on the actual process.

[0012] The utility model also provides a glue sticking machine, comprising the above-mentioned multi-station glue sticking mechanism, feeding mechanism and hot pressing mechanism, the feeding mechanism is arranged at the feeding position of the workpiece conveying member and supplies materials to the workpiece conveying member; the hot pressing mechanism is arranged at the hot pressing position of the workpiece conveying member and the hot pressing mechanism hot presses the glue sticking workpiece conveyed on the workpiece conveying member.

[0014] As a preferred solution of the utility model, a visual monitoring mechanism is installed at the glue sticking station and / or the glue taking station. The visual monitoring mechanism uses a camera or a video camera to obtain the image at the location and transmit it to the controller for processing, and a fill light is also provided in the shooting area to obtain a clear image.

[0015] As a preferred solution of the utility model, a glue sticking monitoring station is provided between the rolling mechanism and the glue taking structure, and a visual monitoring mechanism is provided at the glue sticking monitoring station. After the glue taking structure completes the gluing at the gluing station, the workpiece conveyor continues to convey the glued workpiece downward to the glue sticking monitoring station for gluing quality inspection. The image is judged by the photograph. After the inspection is passed, rolling is performed to squeeze out the bubbles that may exist, and then hot pressing is performed to make the double-sided tape closely contact with the workpiece to complete the gluing of the workpiece surface.

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Example:

[0026] A multi-station glue sticking mechanism, such as Figure 1 As shown, it includes a workpiece conveying member 1, a glue discharging structure 2 and a glue taking structure 3; the workpiece conveying member 1 is provided with a glue sticking station, and the workpiece conveying member adopts a conveyor belt, and conveys the workpieces 5 to be glued side by side during conveying, and conveys at least two materials 5 to be glued at a time, that is, the workpiece conveying member will stop when conveying the materials to be glued to the glue sticking station, and at this time, there will be at least two materials 5 to be glued side by side at the glue sticking station. This embodiment is demonstrated by taking the example of the workpiece conveying member conveying two rows at a time. Of course, it can also be changed to convey one row in groups of two.

[0027] A glue outlet structure 2 is provided on the outer side of the glue laminating station. In the present embodiment, a glue outlet structure 2 is provided on the two outer sides of the glue laminating station respectively. The two glue outlet structures are standby for each other. Initially, one of the glue outlet structures is used first. According to the setting habit, the left side is used as the starting point. When the double-sided adhesive on the left side is used up, the other glue outlet structure, i.e. the glue outlet structure on the right side, is used. This can avoid uninterrupted glue laminating and avoid shutdown due to lack of double-sided adhesive.

[0028] The glue discharging structure 2 is provided with two glue-taking stations in parallel at the position corresponding to the glue-applying station, and each glue-taking station corresponds to a double-sided adhesive tape 6 to be taken. The glue discharging structure uses a double-sided adhesive tape feeding device in the prior art, which will not be described here. The double-sided adhesive tape disc is Figure 1 Not shown in FIG.

[0029] like Figure 2 As shown, the glue picking structure 3 is provided with a horizontal multi-joint manipulator 31 and a lifting and placing glue picking assembly 32. The horizontal multi-joint manipulator 31 is installed across the workpiece conveyor through a U-shaped frame 311. The rotating lifting part of the horizontal multi-joint manipulator 31 is installed with a glue picking bracket 33. A lifting and placing glue picking assembly 32 is installed on both sides of the glue picking bracket 33. The lifting and placing glue picking assembly 32 corresponds to the glue picking station one by one; as shown Figure 3The setting of the glue taking bracket can better install the lifting and placing glue taking component 32, so that it can more accurately correspond to the glue taking station, and the two do not affect each other.

[0030] The lifting and placing glue assembly 32 for obtaining the double-sided adhesive tapes on at least two glue-taking stations at one time switches between the glue-taking station and the glue-applying station under the drive of the horizontal multi-joint manipulator 31. In addition, the workpiece setting direction on the glue-applying station in this embodiment is perpendicular to the setting direction of the double-sided adhesive tape to be taken on the glue-taking station.

[0031] like Figure 3 As shown, each lifting and placing glue picking assembly 32 includes a lifting power member 321, a glue picking substrate 322 and a glue picking adsorption plate 323. The lifting power member 321 uses a lifting cylinder. The lifting power member 321 is installed on the glue picking bracket 33. The telescopic part of the lifting power member 321 is connected to the glue picking substrate 322. The glue picking substrate 322 is provided with a negative pressure channel 3221. Figure 4 As shown, the glue taking adsorption plate 323 is fixed on the lower end surface of the glue taking substrate 322, and the glue taking adsorption plate 323 is provided with an air cavity 3231, and a through adsorption air hole 3232 is arranged at the bottom of the air cavity. Figure 5 As shown, the adsorption pores are connected to the negative pressure channel 3221 through the air cavity. The vacuum equipment is connected to the negative pressure channel. After the lifting power part descends to make the glue-taking substrate contact with the double-sided adhesive to be taken, the gas enters the air cavity from the adsorption pores and then enters the vacuum equipment from the negative pressure channel to form a negative pressure between the adsorption pores and the double-sided adhesive to be taken. The double-sided adhesive to be taken is adsorbed, and then the lifting power part rises and is transferred to the glue sticking station under the drive of the horizontal multi-joint manipulator 31. The horizontal multi-joint manipulator 31 descends to bring the lifting and placing glue assembly 32 close to the workpiece to be glued. The lifting power part 321 descends to make the glue-taking adsorption plate 323 adsorb the double-sided adhesive and press the workpiece to be glued downward. The vacuum equipment stops moving, and the double-sided adhesive is separated from the glue-taking adsorption plate 323 and attached to the workpiece to be glued; at least two pieces of double-sided adhesive are adsorbed each time and the workpieces to be glued that are transported side by side are glued, so as to improve the glue sticking efficiency.

[0032] The horizontal multi-joint manipulator rotates and lifts to control the lifting and placing of the glue assembly to obtain the double-sided tape at the gluing station and transfer it to the gluing station for gluing. After the gluing is completed, the workpiece conveyor transfers the glued workpiece out of the gluing station, and the new workpiece to be glued is transferred to the gluing station to wait for the next gluing. The horizontal multi-joint manipulator uses a Yamaha horizontal multi-joint manipulator.

[0033] In the glue picking and placing actions of this embodiment, the two lifting glue picking and placing components are not synchronized. One lifting glue picking and placing component picks up glue or places glue first, and then the other lifting glue picking and placing component picks up glue or places glue. That is to say, when completing a process action, there will be a height difference between the two lifting glue picking and placing components, and the two lifting cylinders are controlled separately.

[0034] Of course, you can also adsorb or release glue synchronously, and the specific synchronization or asynchronous setting is based on the actual process.

[0035] In the actual production process, the glue sticking of the workpiece, i.e. the thermal insulation pad, is achieved by using a glue sticking machine, such as Figure 6 As shown, the required mechanism is added to the multi-station gluing mechanism, including a loading mechanism 7 which is arranged at the loading station of the workpiece conveying member 1 and feeds the workpiece conveying member 1, and the loading mechanism is provided with a silo 71 and a transplanting module 72, and the transplanting module takes two thermal insulation pads from the silo at a time and places them on the workpiece conveying member 1 for conveying; the workpiece conveying member 1 transports the two rows of thermal insulation pad workpieces to the gluing station and then stops to wait for gluing;

[0036] After the glue taking structure takes glue and glues the heat insulating pad, the rolling mechanism 8 behind the glue taking structure rolls the workpiece with preliminary glue application to ensure that there are no bubbles between the double-sided adhesive and the workpiece adhesive surface. The heat insulating pad after rolling is further transported by the workpiece conveying member 1 and hot pressed by the hot pressing mechanism 9 at the hot pressing station.

[0037] In addition, visual monitoring mechanisms are installed at both the glue sticking station and the glue taking station. The visual monitoring mechanism uses a camera or a video camera to obtain the image at the location and transmit it to the controller for processing. A fill light is also provided in the shooting area to obtain a clear image and guide the glue taking mechanism to accurately obtain the double-sided adhesive and stick it on the thermal insulation pad.

[0038] In addition, a glue sticking monitoring station is provided between the rolling mechanism 8 and the glue taking structure 3, and a visual monitoring mechanism is provided at the glue sticking monitoring station. After the glue taking structure completes the gluing at the gluing station, the workpiece conveyor continues to convey the glued workpiece downward to the glue sticking monitoring station for gluing quality inspection, and judges whether there is any missing glue through the captured image to eliminate the quality defects of missing glue sticking; it saves the personnel for missing glue sticking inspection, and after the inspection is passed, rolling is performed to squeeze out the possible bubbles, and then hot pressing is performed to make the double-sided adhesive and the workpiece in close contact, and the gluing of the workpiece on that side is completed.

[0039] The utility model improves the single-row single-time pick-up and placement to double-row single-time pick-up and placement for two times, thereby reducing the repeated material picking actions of the glue sticking robot, shortening the time, and greatly improving the production capacity.
