Description

Technical Field

[0001] This utility model relates to the technical field of glue-applying pressure plates, and more specifically, to a glue-applying pressure plate assembly and a glue applicator. Background Technology

[0002] As an important type of automated equipment, glue applicators are widely used for precise glue application to ensure the quality and stability of product assembly. Existing glue applicators have significant shortcomings in glue utilization, primarily due to design flaws in the pressure plate inside the glue tank. Specifically, traditional pressure plates have an inverted funnel-shaped bottom. As the glue level in the tank decreases and reaches the bottom, this design fails to effectively pump out the residual glue from the hollow center of the pressure plate, resulting in a large amount of glue remaining in the tank and causing waste.

[0003] There is currently no effective solution to the problem of excessive adhesive residue caused by using a pressure plate pump to extract adhesive in existing technologies. Utility Model Content

[0004] The main purpose of this utility model is to provide a glue-applying pressure plate assembly and a glue applicator to solve the problem of excessive glue residue caused by using a pressure plate pump to extract glue in the prior art.

[0005] To achieve the above objectives, according to one aspect of the present invention, a glue-applying pressure plate assembly is provided, comprising: a pressure head having a suction cavity that is disposed through the pressure head along its axial direction; and a pressure plate body connected to the pressure head, wherein the pressure plate body has a plurality of through holes that are connected to the suction cavity.

[0006] Furthermore, the pressing surface of the pressure plate body on the side opposite to the pressure head is a plane.

[0007] Furthermore, the pressure plate body and the pressure head are detachably connected.

[0008] Furthermore, the pressure plate body is provided with countersunk holes, and the end of the pressure head near the pressure plate body is provided with threaded holes. The threaded holes and countersunk holes are set one-to-one, and the bolts pass through the countersunk holes and threaded holes in sequence to fix the pressure plate body to the pressure head.

[0009] Furthermore, the pressure plate body and the pressure head are connected by threads.

[0010] Furthermore, a sealing ring is provided between the pressure plate body and the pressure head.

[0011] Furthermore, the suction chamber has a conical structure, and the inner diameter of the suction chamber gradually decreases in the direction away from the pressure plate body.

[0012] Furthermore, a connecting section is provided at the end of the pressure head away from the pressure plate body, and the inner diameter of the connecting section is smaller than the inner diameter of the suction chamber.

[0013] Furthermore, the inner diameter of the connecting section is set to be constant along the axial direction of the connecting section.

[0014] According to another aspect of the present invention, a glue applicator is provided, which includes a glue applicator plate assembly, wherein the glue applicator plate assembly is the aforementioned glue applicator plate assembly.

[0015] The technical solution of this utility model involves connecting one end of the pressure head to a pump and the other end to a pressure plate body. Multiple through holes on the pressure plate body communicate with the suction chamber of the pressure head. Under the action of the pump, the adhesive is pumped into the suction chamber through the through holes. When the amount of adhesive in the glue bucket decreases to near the bottom, the pressing surface of the pressure plate body abuts against the bottom of the bucket, effectively sealing the circumference of each through hole to create a large suction force, thereby drawing the adhesive from the bottom of the bucket into the suction chamber. The adhesive coating pressure plate assembly in the above solution overcomes the limitation of traditional pressure plates leaving adhesive residue at the bottom of the glue bucket, achieving efficient utilization of the adhesive and effectively reducing adhesive residue in the glue bucket.

[0027] Combination Figure 1 As shown, according to a specific embodiment of this application, a glue-applying pressure plate assembly is provided.

[0028] Specifically, the adhesive coating plate assembly includes a pressure head 10 and a pressure plate body 20. The pressure head 10 has a suction cavity 11, which is axially connected to the pressure head 10. The pressure plate body 20 is connected to the pressure head 10. The pressure plate body 20 has multiple through holes 21, which are connected to the suction cavity 11.

[0029] In the embodiments of this application, one end of the pressure head 10 is connected to a pump, and the other end of the pressure head 10 is connected to the pressure plate body 20. Multiple through holes 21 on the pressure plate body 20 communicate with the suction chamber 11 of the pressure head 10. Under the action of the pump, the adhesive is pumped into the suction chamber 11 through the through holes 21. When the amount of adhesive in the glue bucket decreases to near the bottom, the pressing surface of the pressure plate body 20 can abut against the bottom of the bucket, effectively sealing the circumference of each through hole 21 to form a large suction force, thereby drawing the adhesive from the bottom of the bucket into the suction chamber 11. The adhesive coating pressure plate assembly in the above solution breaks the limitation of traditional pressure plates leaving adhesive residue at the bottom of the glue bucket, achieving efficient utilization of the adhesive and effectively reducing adhesive residue in the glue bucket.

[0030] It should be noted that the suction port of the pressure plate in the prior art is relatively large. When the pressure plate abuts against the bottom of the barrel, the circumferential sealing of the suction port is poor, and it cannot generate sufficient suction force, that is, it cannot fully pump the rubber material at the bottom of the barrel. In this application, by setting a pressure plate body 20 and setting multiple through holes 21 on the pressure plate body 20, the diameter of the suction port is reduced. Due to the smaller diameter, under the same downward pressure, the smaller the diameter of the suction port, the better the circumferential sealing of the suction port, and the greater the suction force generated; in addition, the smaller the diameter of the suction port, the less suction force is required.

[0031] It should be further noted that the shape of the suction chamber 11 of the pressure head 10 is not limited, and can be a conical structure, a cylindrical structure, etc.

[0032] In one exemplary embodiment of this application, the pressing surface of the pressure plate body 20 on the side opposite to the pressure head 10 is a plane.

[0033] In the embodiments of this application, the pressure plate body 20 contacts the bottom of the glue bucket through the pressing surface. The pressing surface is set as a plane so that the pressure plate body 20 can make complete and uniform contact with the bottom of the bucket, that is, it can better seal the circumference of each through hole 21, so that each through hole 21 can generate sufficient suction force, thereby fully pumping the glue material at the bottom of the bucket.

[0034] As an alternative implementation, the pressing surface of the pressure plate body 20 on the side opposite to the pressure head 10 is an arc surface, and the pressure plate body 20 can deform under the action of external force. That is, under a sufficiently large downward pressure, the pressure plate body 20 can deform, causing the pressing surface to be concave inward, so that the pressing surface deforms to abut against the bottom of the barrel.

[0035] In one exemplary embodiment of this application, the pressure plate body 20 is detachably connected to the pressure head 10.

[0036] In the embodiments of this application, the pressure plate body 20 is detachably connected to the pressure head 10, and different specifications of the pressure plate body 20 can be replaced according to usage requirements; and, after the pressure plate body 20 is damaged, the pressure plate body 20 can be replaced and repaired.

[0037] For example, the pressure plate body 20 is provided with a countersunk hole, and the end of the pressure head 10 near the pressure plate body 20 is provided with a threaded hole. The threaded hole and the countersunk hole are provided in a one-to-one correspondence. The bolt passes through the countersunk hole and the threaded hole in sequence to fix the pressure plate body 20 to the pressure head 10.

[0038] In the embodiments of this application, the pressure plate body 20 is provided with a countersunk hole so that the head of the bolt can be fully inserted into the countersunk head of the countersunk hole, so as to avoid the bolt being exposed and affecting the pressure plate body 20 from being able to fully abut against the bottom of the glue bucket.

[0039] For example, the pressure plate body 20 and the pressure head 10 are connected by threads.

[0040] Specifically, the end of the pressure head 10 near the pressure plate body 20 is provided with an internal thread, and the pressure plate body 20 is provided with an external thread. The pressure plate body 20 and the pressure head 10 are connected by threads, and at least part of the pressure plate body 20 extends into the pressure head 10.

[0041] Preferably, a sealing ring is provided between the pressure plate body 20 and the pressure head 10.

[0042] In the embodiments of this application, the sealing ring is provided to ensure the sealing of the suction chamber 11 of the pressure head 10 so that the suction chamber 11 maintains sufficient suction force.

[0043] In one exemplary embodiment of this application, the suction cavity 11 has a conical structure, and the inner diameter of the suction cavity 11 gradually decreases in the direction away from the pressure plate body 20.

[0044] In the embodiments of this application, the suction chamber 11 is designed as a conical structure, which can form a concentrated negative pressure extraction effect. As the inner diameter of the suction chamber 11 gradually decreases, its efficiency and ability to extract the adhesive are enhanced. Even when the amount of adhesive in the glue bucket is small and the viscosity of the adhesive increases, the adhesive can be effectively extracted, which significantly improves the utilization rate of the adhesive.

[0045] like Figure 1 As shown, the pressure head 10 has a conical structure, and its outer diameter gradually decreases in the direction away from the pressure plate body 20. The suction cavity 11 inside the pressure head 10 has a conical structure, and its inner diameter gradually decreases in the direction away from the pressure plate body 20.

[0046] Furthermore, the end of the pressure head 10 furthest from the pressure plate body 20 is provided with a connecting section 12, the inner diameter of which is smaller than the inner diameter of the suction chamber 11.

[0047] In the embodiments of this application, the design of the inner diameter of the connecting section 12 being smaller than the inner diameter of the suction chamber 11 can form a gradual flow channel. During the process of conveying the adhesive from the suction chamber 11 to the pump, the smaller inner diameter of the connecting section 12 helps to increase the flow rate of the adhesive as it passes through, forming a local high-speed flow, thereby accelerating the extraction rate of the adhesive. Especially when the amount of adhesive in the adhesive bucket decreases and the viscosity increases, this design can significantly improve the extraction efficiency and reduce adhesive residue.

[0048] Preferably, the inner diameter of the connecting section 12 is set to be equal along the axial direction of the connecting section 12.

[0049] In the embodiments of this application, the design of the equal inner diameter of the connecting section 12 helps to maintain the pressure consistency during the transmission of the adhesive. The adhesive will not undergo abrupt changes when passing through the connecting section 12, which reduces the resistance changes caused by abrupt changes in the flow channel size, ensures the continuity and stability of the adhesive transmission, avoids the phenomenon of unstable adhesive extraction or flow interruption caused by pressure fluctuations, and improves the accuracy and efficiency of the adhesive application operation.

[0050] like Figure 1 As shown, the connecting segment 12 is a cylindrical structure.

[0051] According to another specific embodiment of this application, a glue applicator is provided, which includes a glue applicator plate assembly, which is the glue applicator plate assembly in the above embodiment.

[0052] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0053] In addition to the above, it should be noted that the terms "one embodiment," "another embodiment," and "embodiment" used in this specification refer to specific features, structures, or characteristics described in connection with that embodiment, which are included in at least one embodiment described in the general description of this application. The appearance of the same expression in multiple places in the specification does not necessarily refer to the same embodiment. Furthermore, when a specific feature, structure, or characteristic is described in connection with any embodiment, the intention is to suggest that implementing such a feature, structure, or characteristic in conjunction with other embodiments also falls within the scope of this utility model.
