Description

Technical Field

[0001] The invention relates to the technical field of glue dispensing equipment, in particular to an automatic glue dispensing device. Background Art

[0002] In automated production, automatic dispensing devices are commonly used to complete dispensing or gluing operations, and currently conveyor belts are mostly used to transport products. Reliably positioning the conveyed products at the dispensing station has become a key step in the dispensing process.

[0003] For example, a Chinese utility model patent with authorization announcement number CN209680463U and authorization announcement date 2019.11.26 discloses a PCB product clamping device for a dispensing machine, and specifically discloses that the dispensing machine includes a conveying mechanism and a lifting mechanism disposed below the conveying mechanism, and the PCB product clamping device of the dispensing machine includes four clamping members, and the four clamping members are disposed on the conveying mechanism for clamping the PCB product, so that the PCB product conveyed by the conveying mechanism is clamped by the four clamping members after being lifted by the lifting mechanism, and a transmission gap is formed between the clamped PCB product and the conveying mechanism. The two clamping members are mounted on the first pressing plate through the first mounting seat, and a clamping member includes a cylinder, a clamping claw driven by the cylinder, and an upper pressing plate disposed above the clamping claw, and the cylinder drives the clamping claw to move, so that the PCB product is clamped between the clamping claw and the upper pressing plate.

[0004] When using the existing glue dispenser to clamp and position the PCB product, it is necessary to control the coordination of the lifting mechanism and the four clamping parts to effectively position the PCB product. The structure of the clamping device is complex and the control process is cumbersome. Moreover, in actual use, the product to be dispensed is not limited to PCB, but may also be other plate-like or sheet-like materials (hereinafter collectively referred to as "material plates"). Due to the shape and material limitations of the material plates, the clamping position and clamping area need to be flexibly adjusted.

[0005] In summary, the existing dispensing machines have problems such as complex structure, cumbersome clamping control process, and inability to flexibly adjust the clamping position and clamping area. Summary of the invention

DETAILED DESCRIPTION

[0027] The specific implementation of the present invention is further described in detail below in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0028] A specific embodiment 1 of the automatic dispensing device of the present invention is as follows Figures 1 to 5 As shown, the automatic glue dispensing device includes a machine base 1, a conveying mechanism 2 installed on the machine base 1, a lifting mechanism 3 and a pressing structure 4, and an image acquisition module 7 and a glue dispensing module 6 installed on the upper side of the conveying mechanism 2; the pressing structure 4 is arranged on the outer side of the conveying mechanism 3, and the pressing structure 4 includes a base plate 41 and an adjustable pressing plate 42, a lifting interval 40 is reserved between the base plate 41 and the conveying mechanism 3, the adjustable pressing plate 42 is adjustably installed on the upper side of the base plate 41, and the adjustable pressing plate 42 has an upper clamping portion cantilevered to the inner side of the base plate 41, and a carrying space for accommodating the conveying of the material plate is reserved between the upper clamping portion and the upper surface of the conveying mechanism 2; the lifting mechanism 3 includes a lifting drive member 30, a lifting clamping plate 31 installed on the upper part of the lifting drive member 30, the lifting clamping plate 31 is movably installed up and down in the lifting interval 40 between the base plate 41 and the conveying mechanism 2, and the upper edge of the lifting clamping plate 31 constitutes a lower clamping portion for pressing the material plate.

[0029] The conveying mechanism 2 includes two conveyor belts 21 arranged in parallel and at intervals, and a transmission roller 20. The two conveyor belts 21 are respectively the first conveyor belt and the second conveyor belt. The lifting drive member 30 is arranged between the first conveyor belt and the second conveyor belt. The first conveyor belt and the second conveyor belt are respectively connected to the two ends of the transmission roller 20 by transmission. The two conveyor belts 22 are synchronously driven by a transmission roller 20 to achieve the purpose of smoothly conveying the material plate. In addition, there are two base plates 41, which are respectively the first base plate and the second base plate. The first base plate is arranged at intervals on the outside of the first conveyor belt, and the second base plate is arranged at intervals on the outside of the second conveyor belt. That is, a lifting interval 40 is formed between the first conveyor belt and the first base plate, and a lifting interval 40 is also formed between the second conveyor belt and the second base plate.

[0030] Furthermore, both base plates 41 are strip-shaped vertical plates extending parallel to the conveying direction of the conveying mechanism 2. A pad 43 is fixed on the upper side of the base plate 41. The pad 43 is provided with a plurality of assembly holes 430 spaced apart along the conveying direction of the conveying mechanism 2. A clamping bolt (not shown in the figure) is connected between the adjustable pressure plate 42 and the assembly holes 430. The adjustable pressure plate 42 is fastened to the pad 43 by the clamping bolt. Different clamping positions can be selected according to the actual situation of the material plate so that the adjustable pressure plate 42 is fastened to the assembly holes 430 at different positions of the pad 43.

[0031] In the present embodiment, the adjustable pressing plate 42 is narrow in front and wide in the back, and an elongated hole 420 is provided at the back of the adjustable pressing plate 42. The front of the adjustable pressing plate 42 constitutes an upper clamping portion that overhangs to the inner side of the base plate 41. Specifically, the adjustable pressing plate 42 is a "Y"-shaped pressing plate, and the "Y"-shaped pressing plate includes a front narrow section 421 and a rear wide section 422. The elongated hole 420 extends along the length direction of the front narrow section 421 and is arranged in the middle of the rear wide section 422 of the "Y"-shaped pressing plate. The adjustable pressing plate 42 is designed to be narrow in front and wide in the back, which reduces the clamping surface of the upper clamping portion of the adjustable pressing plate 42, ensures that the clamping area of ​​the adjustable pressing plate 42 on the material plate is small enough, and effectively avoids the problem of interference with other parts of the material plate during clamping and positioning. Moreover, the elongated hole 420 enables the adjustable pressure plate 42 to have the flexibility to be freely adjusted in a plane. The length of the overhanging upper clamping portion can be changed by translating the adjustable pressure plate 42, and the clamping position of the upper clamping portion can be changed by rotating the adjustable pressure plate 42, thereby achieving the purpose of flexibly adjusting the clamping position and clamping area of ​​the material plate according to actual conditions.

[0032] In order to ensure a stable clamping effect between the lifting clamp plate 31 and the adjustable pressure plate 42, two lifting clamp plates 31 are also provided, and the plate surfaces of the lifting clamp plates 31 are arranged parallel to the plate surfaces of the base plate 41, one of the lifting clamp plates 31 is guided and installed in the lifting interval 40 between the first base plate and the first conveyor belt, and the other lifting clamp plate is guided and installed in the lifting interval 40 between the second base plate and the second conveyor belt. Specifically, a vertically extending guide rail is fixed on the inner plate surface of the base plate 41, and a vertically extending guide groove is correspondingly provided on the outer plate surface of the lifting clamp plate 31. The guide rail and the guide groove are slidably matched to ensure the movement accuracy of the upward clamping action of the lifting clamp plate 31.

[0033] The lifting driving member 30 drives the lifting clamp 31 to move upward, firstly lifting the material plate through the lower pressing part located at the upper edge of the lifting clamp 31, so that the material plate is separated from the upper surface of the conveyor belt 21, and then continuing to press the material plate upward until it is stopped by the adjustable pressing piece 42, and the lower pressing part of the lifting clamp 31 and the upper pressing part of the adjustable pressing piece 42 are used to clamp the material plate, thereby achieving the purpose of clamping and positioning the material plate. In the whole control process, only the lifting driving member 30 is controlled to perform the lifting action, and the lifting clamp 31 cooperates with the adjustable pressing piece 42 to complete the function of lifting the material plate and clamping and positioning, and the whole structure and control process are simpler.

[0034] Specifically, the lifting drive 30 is a scissor-type lifting device, which includes a scissor arm and a driving cylinder. The extension and contraction of the driving cylinder drives the rotation of the scissor arm, thereby realizing the upward lifting and downward lowering actions. A support plate 32 is also provided on the upper part of the lifting drive 30. It should be noted that in order to facilitate the intuitive understanding of the structure of the lifting drive 30, Figure 2 , Figure 5 In the figure, the lifting drive member 30 is exposed to the upper part of the support plate 32, but in fact, the support plate 32 is installed on the upper part of the lifting drive member 30. The lower part of the two lifting clamps 31 is also connected with a top column 33, which is vertically pressed with the support plate 32, and the top column 33 includes an upper column section and a lower column section, and the upper column section and the lower column section are threadedly assembled and connected. When the conveying mechanism 2 normally transports the material plate, the lifting drive member 30 is in the retracted position, the support plate 32 drops to the lowest position and separates from the top column 33; when the material plate needs to be clamped, the lifting drive member 30 works to drive the support plate 32 to rise, and when the support plate 32 is pressed into contact with the top column 33, the lifting clamp 31 begins to be lifted.

[0035] In order to ensure the synchronization of the support plate 32 lifting the two lifting clamps 31, at least three lifting driving members 30 are provided, and at least three lifting driving members 30 are distributed circumferentially around the center of the support plate 32. In this embodiment, four lifting driving members 30 are provided, and the four lifting driving members 30 are distributed circumferentially around the center of the support plate 32, and the four lifting driving members 30 are respectively arranged at the four vertices of the square. The four lifting driving members 30 jointly lift the support plate 32, ensuring that the plate surface of the support plate 32 is always in a horizontal plane, thereby ensuring that the material plate is clamped synchronously when pressing the two lifting clamps 31.

[0036] In addition, the automatic glue dispensing device also includes a stop mechanism 5, which includes a stop driving member 50 and a stop plate 51. The driving direction of the stop driving member 50 is set vertically, and the stop plate 51 is an L-shaped folding plate. The L-shaped folding plate includes a horizontal edge 511 and a vertical side 510. The vertical side 510 is used to cooperate with the front edge of the material plate. When the glue dispensing station is clamping and positioning the material plate, the stop driving member 50 drives the stop plate 51 to move upward, so that the vertical side 510 is higher than the upper surface of the conveyor belt 21, so as to form a stop effect on the subsequent material plate, thereby ensuring that the material plate of the glue dispensing station completes the glue dispensing smoothly, and avoiding the problem of subsequent material plates colliding and being damaged by the lifting mechanism 3. The image acquisition module 7 is an industrial camera, which is used to capture the plane image of the material sheet, so as to determine the dispensing position of the material sheet. The dispensing module 6 is movably installed on the upper side of the conveying mechanism. The dispensing module 6 includes a glue storage container, a dispensing valve and a connecting hose. According to the image of the material sheet obtained by the image acquisition module 7, the dispensing module 6 moves along the planned path and performs the dispensing operation at the determined dispensing position.

[0037] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principles of the present invention. These improvements and substitutions should also be regarded as the scope of protection of the present invention.
