Abstract
Description
Technical Field
[0001] This utility model relates to the field of glue applicator technology, specifically a protective structure and a glue applicator. Background Technology
[0002] A glue applicator, also known as a glue applicator, glue applicator, or glue dispensing machine, is a device specifically designed to control fluids (such as glue, silicone, epoxy resin, etc.) and to precisely apply a predetermined amount of glue to a specific location.
[0003] The patent with publication number CN220496802U discloses a desktop dispensing machine, including: a workbench, a gantry frame, a dispensing head, and a cooling mechanism. The cooling mechanism includes a cooling jacket, a heat exchange frame, and a fan. A delivery pipe is connected to the top of the cooling jacket. The heat exchange frame is fixedly placed on the side wall of the cooling jacket, and a cooling plate is installed inside the heat exchange frame. The cooling end of the cooling plate is provided with a first heat exchange plate inserted into the cooling jacket, and the heat dissipation end of the cooling plate is provided with a second heat exchange plate located inside the heat exchange frame. The fan is placed on the side wall of the heat exchange frame. Cooling is achieved through a semiconductor cooling plate. Only a fan needs to be installed on the surface, which greatly reduces the volume of the cooling structure and facilitates the layout of the dispensing machine. The second heat exchange plate carries away the heat from the heat dissipation end of the cooling plate and exhausts it through the fan. The first heat exchange plate cools the adhesive inside the cooling jacket at the cooling end of the cooling plate, which can effectively improve the cooling effect and effectively prevent the adhesive from being difficult to dispense due to excessive viscosity.
[0004] However, the above-mentioned dispensing machine still has the following problems in actual use:
[0005] Desktop dispensing machines are typically placed directly on a desktop and operated by an automated control system. They achieve precise dispensing of adhesive to workpieces on a substrate through precise control of the X, Y, and Z axes. However, since dispensing operations are conducted in an open environment, if an operator or object accidentally enters the machine's movement range during dispensing, it may collide with the moving dispensing head, resulting in equipment damage. Utility Model Content
[0006] To address the shortcomings of existing technologies, this utility model provides a protective structure and a glue applicator, which can protect the outer periphery of the glue applicator's stroke during operation.
[0007] To achieve the above objectives, the present invention provides the following technical solution: a protective structure, comprising two protective shells fixedly installed at both ends of the front side of a base plate, each of the two protective shells having a transmission assembly inside, the adjacent ends of the two transmission assemblies being connected to a front plate, the distant ends of the two transmission assemblies being connected to side plates, the two side plates and the front plate forming a U-shaped frame, the middle of the base plate being located within the U-shaped frame.
[0008] Furthermore, the transmission assembly includes a first rod, a first bevel gear, a second bevel gear, and a second rod. The first and second bevel gears are both located inside the protective shell and mesh with each other. The first bevel gear is sleeved and fixedly connected to the outer wall of one end of the first rod. The other end of the first rod passes through the protective shell and the side plate and is fixedly connected to the side plate. The second bevel gear is sleeved and fixedly connected to the outer wall of one end of the second rod. The other end of the second rod passes through the protective shell and the front plate and is fixedly connected to the front plate.
[0009] Furthermore, two side plates are fixedly connected to raised blocks on both sides away from the first pole. Infrared receivers and infrared transmitters are fixedly connected to both sides of the raised blocks, and the infrared receivers and infrared transmitters on adjacent raised blocks are matched and aligned.
[0010] This utility model also provides a glue applicator, including the above-mentioned protective structure, and further including a base plate, a moving and dispensing mechanism installed on the rear side of the base plate, and a storage plate installed in the middle of the base plate. The front plate is located on the side of the base plate away from the moving and dispensing mechanism, and the two side plates are respectively located on both sides of the storage plate.
[0011] Furthermore, folding openings are provided on both sides of the base plate, and the ends of the two No. 1 rods away from the No. 1 bevel gear are rotatably connected to the inner walls of the two folding openings respectively.
[0012] Furthermore, the bottom surface of both folding openings is provided with storage openings, and the inner walls of both storage openings are rotatably connected with stop bars, the side walls of the stop bars abutting against the side walls of the side plates.
[0013] Furthermore, both storage openings have pull tabs on the side away from the side panel.
[0014] Compared with the prior art, the present invention has the following beneficial effects:
[0015] 1. This type of protective structure and glue applicator uses a bevel gear transmission assembly to achieve synchronous linkage between the front plate and the two side plates. Only one plate needs to be moved to complete the quick switching between the protective structure in the upright (blocking state) and flat (material loading and unloading state), which is convenient to operate and reduces the workpiece loading and unloading time.
[0016] 2. This type of protective structure and glue applicator is equipped with an infrared transmitter and receiver at the end of the side plate to form a three-dimensional monitoring area. When a foreign object enters the protection range, it can immediately trigger a shutdown alarm to avoid collision between the glue applicator head and the foreign object, thereby reducing the risk of equipment damage.
[0017] 3. The protective structure and glue applicator have folding and storage openings on both sides of the base plate, which allows the side plates to be laid flat below the base plate, without taking up vertical space and making it easy to pick up and put away large workpieces, thus adapting to diverse production scenarios.
[0018] 4. In this type of protective structure and glue applicator, the rotatable stop bar inside the receiving port abuts against the side wall of the side plate when in the protective state, effectively preventing the protective structure from being accidentally deployed during equipment operation and ensuring the continuity and safety of the processing process.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0026] Please see Figures 1-5 A protective structure includes two protective shells 8 fixedly installed at both ends of the front side of a base plate 1. Each of the two protective shells 8 has a transmission component inside. The adjacent ends of the two transmission components are connected to a front plate 4. The opposite ends of the two transmission components are connected to side plates 5. The two side plates 5 and the front plate 4 form a U-shaped frame. The middle part of the base plate 1 is located inside the U-shaped frame.
[0027] like Figures 1 to 5 As shown, in use, the protective structure of this utility model can be operated by simply moving the front plate 4 or any one of the side plates 5 by hand. Due to the action of the two transmission components, the front plate 4 and the two side plates 5 will rotate together, thus allowing it to be erected (in a covered state, such as...) Figure 1 ) and flat (material handling state, such as) Figure 3It allows users to switch freely between different modes, and the operation is convenient and quick.
[0028] As a preferred embodiment of this utility model, the transmission assembly includes a first rod 11, a first bevel gear 12, a second bevel gear 13, and a second rod 14. The first bevel gear 12 and the second bevel gear 13 are both located inside the protective shell 8 and are meshed. The first bevel gear 12 is sleeved and fixedly connected to the outer wall of one end of the first rod 11. The other end of the first rod 11 passes through the protective shell 8 and the side plate 5 and is fixedly connected to the side plate 5. The second bevel gear 13 is sleeved and fixedly connected to the outer wall of one end of the second rod 14. The other end of the second rod 14 passes through the protective shell 8 and the front plate 4 and is fixedly connected to the front plate 4.
[0029] More specifically, when the front plate 4 or any side plate 5 is moved, the side plate 5 will be rotated by the first rod 11 after being subjected to force. When the first rod 11 rotates, it will also rotate the first bevel gear 12 located inside the protective shell 8. Then the first bevel gear 12 will rotate the second bevel gear 13, which will then rotate the front plate 4. Subsequently, the front plate 4 can rotate the other side plate 5 together through the first bevel gear 12 and the second bevel gear 13 inside the other protective shell 8.
[0030] As a preferred embodiment of this utility model, both sides of the two side plates 5 away from the first rod 11 are fixedly connected to the raised blocks 6. Infrared receivers 7 and infrared transmitters 10 are fixedly connected to both sides of the raised blocks 6 respectively, and the infrared receivers 7 and infrared transmitters 10 on the two adjacent raised blocks 6 are matched and aligned.
[0031] More specifically, by setting up a shim block 6, and then setting up an infrared receiver 7 and an infrared transmitter 10 on the shim block 6, an additional monitoring function can be provided between the side panel 5 and the front panel 4 when they are in a blocked state. Because of the blocking effect of the side panel 5 and the front panel 4, although foreign objects will not directly hit the workpiece being processed, they may still collide with components such as the dispensing head. Therefore, the infrared receiver 7 and the infrared transmitter 10 can immediately issue an alarm when they detect that a foreign object has entered the blocked range, and at the same time, the equipment will stop, allowing the staff to conduct a timely inspection.
[0032] This utility model also provides a glue applicator, including the above-mentioned protective structure, and further including a base plate 1, a moving and dispensing mechanism 2 installed on the rear side of the base plate 1, and a placement plate 3 installed in the middle of the base plate 1. The front plate 4 is located on the side of the base plate 1 away from the moving and dispensing mechanism 2, and the two side plates 5 are respectively located on both sides of the placement plate 3.
[0033] More specifically, through the above arrangement, the bottom plate 1, the moving and dispensing mechanism 2 and the storage plate 3 can be completely covered inside by the side plate 5 and the front plate 4, so that they will not be directly obstructed by external objects during operation.
[0034] It should be noted that the desktop glue dispensing machine is a mature existing technology. In addition to the base plate 1, the moving and dispensing mechanism 2, and the placement plate 3, it also includes, but is not limited to, a control system responsible for parameter setting, motion trajectory planning, and process control; and a drive system that provides power to the mechanical structure to ensure that the dispensing head moves along the preset trajectory.
[0035] In addition, the moving and dispensing mechanism 2 includes, but is not limited to: a dispensing actuator that directly contacts the adhesive and completes the dispensing; and an adhesive supply system that is responsible for storing and transporting the adhesive, ensuring that the adhesive is supplied to the actuator at a stable pressure and flow rate, and avoiding adhesive interruption or air bubbles.
[0036] As a preferred embodiment of this utility model, folding openings 301 are provided on both sides of the base plate 1, and the ends of the two rods 11 away from the bevel gear 12 are respectively rotatably connected to the inner walls of the two folding openings 301.
[0037] More specifically, by setting the folding opening 301, storage can be provided for the two side panels 5 when unfolded, avoiding taking up space above the base plate 1.
[0038] As a preferred embodiment of this utility model, the bottom surfaces of the two folding openings 301 are provided with storage openings 302, and the inner walls of the two storage openings 302 are rotatably connected with a stop bar 9, the side wall of the stop bar 9 abutting against the side wall of the side plate 5.
[0039] More specifically, by setting up the storage opening 302 and the stop bar 9, the stop bar 9 can be erected together with the side plate 5 after it is erected, so that the stop bar 9 can block the outside of the side plate 5, thereby preventing the side plate 5 and the front plate 4 from unfolding on their own during processing, thus affecting the protective effect.
[0040] As a preferred embodiment of this utility model, each of the two storage openings 302 has a pull-out opening 303 on the side away from the side plate 5.
[0041] More specifically, by setting the lifting port 303, the stop bar 9 can be completely stored in the storage port 302 when the side panel 5 is unfolded. At the same time, when the stop bar 9 needs to be pulled out again later, it is easier to pry it out.
[0042] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
