DETAILED DESCRIPTION

[0018] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of this application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not used to limit the scope of the present invention.

[0019] refer to Figure 1 and Figure 2 The present invention provides a high temperature glue printing device 100, which is used to dispense glue to a workpiece so that the workpiece can complete subsequent bonding work. The amount of glue dispensed by the high temperature glue printing device 100 for the workpiece can be basically consistent each time, and the workpiece will basically not have too much or too little glue dispensed, which not only saves glue liquid, but also ensures that the workpiece has enough glue liquid for subsequent bonding processes.

[0020] The high-temperature glue printing device 100 includes a shell component 1, a glue delivery component 2 and a glue dispensing drive component 3, wherein the shell component 1 is used to place the workpiece to be glued, the glue delivery component 2 and the glue dispensing drive component 3 are both arranged in the shell component 1, the glue delivery component 2 is connected to the glue dispensing drive component 3, and is used to deliver glue to the glue dispensing drive component 3, so that the glue dispensing drive component 3 can flow the glue through the shell component 1 into the workpiece when moving, so as to dispense glue on the workpiece.

[0021] refer to Figure 3 and Figure 5 The housing assembly 1 includes a housing 11 and a storage platform 12 connected to each other. The housing 11 is provided with a first channel 111 and a second channel 112. The second channel 112 and the first channel 111 are connected to each other to form a glue delivery channel. One end of the second channel 112 is connected to the first channel 111 and is perpendicular to each other, and the other end of the second channel is roughly Z-shaped.

[0022] refer to Figure 2 and Figure 4 The storage platform 12 includes a collar 121 and a storage plate 122. A through hole is provided in the middle of the collar 121. The collar 121 is connected to the housing 11 and the storage plate 122 is fixed between the collar 121 and the housing 11 to fix the storage plate 122. In one embodiment, the collar 121 can be connected to the housing by a threaded connection, which is convenient for disassembly and assembly. The storage plate 122 is provided with a glue outlet hole 123, and a storage groove 124 is formed between one side of the storage plate 122 and the hole wall of the through hole, and the storage groove 124 is used to place the workpiece. Clamping holes 125 are provided on both sides of the storage plate 122, and the housing 11 has a positioning column 114. The positioning column 114 and the clamping hole 125 are plugged together to completely fix the storage plate 122.

[0023] The shape and size of the placement groove 124 can be adapted to the workpiece, so that when the workpiece is placed in the placement groove 124, the workpiece can be positioned, and the workpiece can be guaranteed to completely cover the glue outlet hole 123, and the glue of the glue drive assembly 3 can directly contact the workpiece through the glue outlet hole 123, thereby completing the dispensing of the workpiece. Figure 2 The placement groove 124 of the illustrated embodiment is circular and can be used to position a circular workpiece. In other embodiments, the placement groove 124 can also be set to a rectangular or regular polygonal shape, etc., which can be specifically set according to the shape of the workpiece.

[0024] The number of the glue outlet holes 123 is not limited and can be one or more. Figure 4 In the embodiment shown, the storage plate 122 has two glue outlet holes 123 extending through the thickness direction thereof. The glue of the glue outlet drive assembly 3 can simultaneously flow into the workpiece through the two glue outlet holes 123. Compared with having only one glue outlet hole 123, the workpiece of this embodiment obtains more glue dots, and has better viscosity later, which is beneficial to the subsequent bonding process. In other embodiments, the number of glue outlet holes 123 is not limited, for example, it can also be three or more, which can be determined according to the number of glue dots required for the workpiece.

[0025] refer to Figure 5 and Figure 6 The glue liquid conveying assembly 2 includes a glue raw material tank 21, a suction cylinder 22, a piston 23, a first one-way valve 24 and a second one-way valve 25. The housing 11 is also provided with a discharge channel 113. The two ends of the discharge channel 113 are connected to the glue raw material tank 21 and the first channel 111. The first one-way valve 24 is arranged at the connection between the discharge channel 113 and the first channel 111, and is used to open or close the connection. The second one-way valve 25 is arranged at the connection between the first channel 111 and the second channel 112, and is used to open or close the connection. The piston 23 is slidably connected to the housing 11, and the suction cylinder 22 is connected to the piston 23 and is used to drive the piston 23 to slide back and forth.

[0026] refer to Figure 2 The glue storage raw material tank 21 has a feeding port 211, an observation transparent column 212 and a sealing plug 213. The sealing plug 213 is threadedly connected to the feeding port 211 and is used to open or seal the feeding port 211. When it is necessary to replenish the glue liquid for the glue storage raw material tank 21, the staff can first open the sealing plug 213 and add the glue liquid from the feeding port 211. The glue liquid passes through the observation transparent column 212 and enters the inside of the glue storage raw material tank 21 to replenish the glue liquid. The glue liquid level of the observation transparent column 212 is consistent with the glue liquid level inside the glue storage raw material tank 21. The staff can check whether the glue liquid inside the glue storage raw material tank 21 is sufficient by observing the transparent column 212, so as to prompt the staff to replenish the glue in time.

[0027] In the above manner, a sufficient amount of glue liquid can be stored in the glue storage raw material tank 21 in advance. When the suction cylinder 22 drives the piston 23 to slide away from the first one-way valve 24, the piston 23 drives the first channel 111 to form a negative pressure, and the negative pressure drives the first one-way valve 24 to open. The glue liquid in the glue storage raw material tank 21 flows into the first channel 111 through the discharge channel 113. At the same time, the negative pressure drives the second one-way valve 25 to close, so as to avoid the first channel 111 from losing pressure and being unable to suck the glue liquid.

[0028] When the suction cylinder 22 drives the piston 23 to slide toward the first one-way valve 24, the piston 23 compresses the first channel 111, pressurizes the first channel 111, and the air pressure drives the first one-way valve 24 to block the discharge channel 113, and at the same time, the air pressure drives the second one-way valve 25 to open, so as to drive the glue liquid in the first channel 111 to enter the second channel 112. As the suction cylinder 22 drives the piston 23 to slide back and forth continuously, the glue liquid in the second channel 112 gradually accumulates, and finally flows into the glue discharge drive assembly 3 driven by the air pressure, and continuously supplies glue liquid to the glue discharge drive assembly 3.

[0029] The principle of sucking glue by the glue delivery component 2 is similar to that of a water pump for pumping well water, both of which use two one-way valves to cooperate with each other and combine with air pressure to extract the liquid and deliver it to the target location.

[0030] The structures of the first one-way valve 24 and the second one-way valve 25 are not limited, for example, they can both be composed of a sealing plate and a torsion spring. The sealing plate is rotatably connected to the housing through the torsion spring. When the sealing plate is subjected to air pressure, the air pressure can drive the sealing plate to rotate to open the corresponding channel, and at the same time, the sealing plate drives the torsion spring to accumulate elastic force. When the sealing plate is not subjected to air pressure, the torsion spring releases the elastic force to drive the sealing plate to automatically seal the corresponding channel.

[0031] Figure 6 The first one-way valve 24 of the illustrated embodiment includes a first spring 241 and a first ball 242, both of which are located in the first channel 111, and one end of the first spring 241 abuts against the step of the first channel 111, and the other end abuts against the first ball 242. The first ball 242 is used to block or open the outlet of the discharge channel 113. When the piston 23 slides away from the first spring 241, the first channel 111 is in a negative pressure state, and the first ball 242 presses the first spring 241 under the drive of the negative pressure, and the first spring 241 is compressed to accumulate elastic force, and at the same time, the first ball 242 opens the outlet of the discharge channel 113, and the negative pressure is transmitted to the glue storage raw material tank 21 through the discharge channel 113, driving the glue liquid in the glue storage raw material tank 21 to enter the first channel 111. When the piston 23 stops sliding away from the first spring 241, the first spring 241 automatically releases the elastic force to drive the first ball 242 to block the outlet of the discharge channel 113.

[0032] Figure 6The second one-way valve 25 of the illustrated embodiment includes a second spring 251 and a second ball 252, both of which are located in the second channel 112, and one end of the second spring 251 abuts against the step of the second channel 112, and the other end abuts against the second ball 252. The second ball 252 is used to block or open the entrance of the second channel 112. When the piston 23 slides away from the first spring 241, the first channel 111 is in a negative pressure state, and the second ball 252 blocks the entrance of the second channel 112 under the dual drive of the negative pressure of the first channel 111 and the second spring 251, and the first channel 111 continuously enters the glue liquid. When the piston 23 slides toward the first spring 241, the air pressure of the first channel 111 continues to increase, and the first ball 242 blocks the outlet of the discharge channel 113 under the pressure of the first spring 241 and the first channel 111; at the same time, the air pressure of the first channel 111 drives the second ball 252 to open the entrance of the second channel 112, driving the glue in the first channel 111 into the second channel 112, and at the same time, the second ball 252 compresses the second spring 251 to accumulate elastic force. When the piston 23 stops sliding toward the first spring 241, the second spring 251 automatically releases its elastic force to drive the second ball 252 to re-block the entrance of the second channel 112.

[0033] The first channel 111 and the second channel 112 together form a glue delivery channel, and the glue liquid in the glue storage raw material tank 21 is transported to the glue output drive assembly 3 through the glue delivery channel under the action of the suction cylinder 22 .

[0034] refer to Figure 7 , Figure 8 and Fig. 9 The glue discharging drive assembly 3 includes a glue holding part 31, a driving motor 32 and a gear set 33, and the gear set 33 meshes with the glue holding part 31 and the driving motor 32 at the same time. The glue holding part 31 is rotatably connected to the housing 11, and the driving motor 32 can drive the gear set 33 to rotate by meshing, so that the gear set 33 drives the glue holding part 31 to rotate by meshing. The glue holding part 31 is used to receive the glue liquid conveyed by the second channel 112. During the rotation process, the glue holding part 31 can align the glue liquid with the glue outlet hole 123 of the storage plate 122, so that the glue liquid flows through the glue outlet hole 123 to the workpiece located on the storage plate 122, so as to dispense glue to the workpiece.

[0035] The gear set 33 includes a driving gear 331, a transmission gear 332 and a driven gear 333 that are meshed in sequence. The driven gear 333 is clamped on the glue container 31 through a latch 334. The driving motor 32 is connected to the driving gear 331 and can drive the driving gear 331 to rotate, so that the driving gear 331 drives the glue container 31 to rotate through the transmission gear 332 and the driven gear 333 in sequence.

[0036] The driven gear 333 has a first slot 335, and the plastic container 31 has a second slot 311. The second slot 311 is engaged with the first slot 335 via a latch 334, so that the plastic container 31 can rotate with the driven gear 333. In other embodiments, the driven gear 333 and the plastic container 31 can also be connected in other ways, such as welding.

[0037] An annular groove 312 is formed in the middle of the glue holding member 31 along the circumference thereof. When the glue holding member 31 rotates, the annular groove 312 can be connected to the second channel 112 all the time, so that the glue liquid from the second channel 112 can continuously flow into the annular groove 312 without being affected by the rotation of the glue holding member 31 .

[0038] A recovery groove 313 is provided at the top of the glue holding member 31. The recovery groove 313 is provided with a boss 314. A glue storage groove 315 is provided at the top of the boss 314. A gluing channel 316 is provided along the length of the glue holding member 31. The inlet of the gluing channel 316 is connected to the annular groove 312. The outlet of the gluing channel 316 is connected to the glue storage groove 315. Therefore, the glue in the annular groove 312 can flow to the glue storage groove 315 through the gluing channel 316 under the action of air pressure. The above-mentioned placement plate 122 is arranged close to the glue storage groove 315, so that when the glue holding member 31 is rotating, the glue in the glue storage groove 315 can flow to the workpiece through the glue outlet hole 123 of the placement plate 122 to dispense glue on the workpiece.

[0039] The boss 314 is eccentrically arranged and is not arranged on the rotating shaft of the glue holding member 31, so that when the glue holding member 31 rotates, the glue storage tank 315 on the boss 314 can be aligned or misaligned with the glue outlet hole 123. When the glue storage tank 315 is aligned with the glue outlet hole 123, the glue in the glue storage tank 315 can flow into the glue outlet hole 123 to dispense glue to the workpiece. When the glue storage tank 315 is misaligned with the glue outlet hole 123, the glue in the glue storage tank 315 cannot flow into the glue outlet hole 123.

[0040] The high temperature glue printing device can work in conjunction with a manipulator, which is used to place the workpiece in the storage tank 124 or take out the workpiece that has been glued from the storage tank 124. The speed of the drive motor 32 can be adjusted automatically, for example, it can be adjusted so that during the period from when the manipulator takes out the workpiece that has been glued to when the next workpiece to be glued is placed in the storage tank 124, the glue storage tank 315 will not pass through the glue outlet hole 123 again. It can also be understood that the glue storage tank 315 cannot pass through the glue outlet hole 123 when the storage tank 124 is empty, so that the glue in the glue outlet hole 123 will not overflow into the storage tank 124, causing pollution to other parts of the workpiece.

[0041] The multiple glue outlet holes 123 opened on the above-mentioned storage plate 122 can be arranged along the extension direction of the glue storage groove 315, so that when the glue holding member 31 rotates, it can drive the glue storage groove 315 to align multiple glue outlet holes 123 at the same time, dispensing glue for multiple parts of the workpiece, thereby improving the adhesion of the workpiece.

[0042] The glue holding member 31 is provided with a recycling channel 317, one end of which is connected to the recycling groove 313, and the other end is connected to the glue storage raw material tank 21. The recycling groove 313 is connected to the glue storage groove 315. The glue overflowing from the glue storage groove 315 can flow into the recycling channel 317 through the recycling groove 313, and finally flow back to the glue storage raw material tank 21, which is conducive to saving glue. Therefore, the entire glue circulation of the high-temperature glue printing device is equivalent to a circulation circulation, which can not only continuously supply glue to the glue outlet hole 123, but also recycle the unused glue for secondary use.

[0043] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by any technician familiar with the technical field within the technical scope disclosed by the present invention should be covered within the protection scope of the present invention.
