Description

Technical Field

[0001] This utility model relates to the field of glue dispensing machines, specifically to an automatic glue dispensing machine with a weighing sensor. Background Technology

[0002] In numerous industries such as electronics manufacturing, automotive parts production, and handicrafts processing, potting is a crucial step in ensuring the sealing, insulation, waterproofing, and structural strength of products. Traditional potting methods rely primarily on manual operation, which is not only labor-intensive and inefficient but also makes it difficult to guarantee the accuracy and consistency of the potting amount, resulting in inconsistent product quality and a high defect rate.

[0003] With the continuous development of industrial automation technology, automatic glue dispensing machines have emerged, greatly improving the efficiency and accuracy of glue dispensing operations. However, existing automatic glue dispensing machines still have some shortcomings in practical applications. On the one hand, some automatic glue dispensing machines only have the function of dispensing glue and lack the step of detecting the weight of the product after dispensing. Due to problems such as unstable glue flow, glue head blockage or leakage during the dispensing process, the actual dispensing volume may deviate from the set value. If this is not detected and handled in time, it will affect the quality and performance of the product. On the other hand, some automatic glue dispensing machines with weighing functions have poorly designed weighing devices, making it difficult to guarantee weighing accuracy and stability. Furthermore, errors are prone to occur during product transportation and positioning, affecting the accuracy of the weighing results.

[0004] In addition, existing automatic dispensing machines have room for improvement in terms of equipment structure layout, component installation stability, and automation control. For example, the overall structure of the equipment is not compact enough and occupies a large space; the installation of moving parts such as cylinders is not stable enough, and they are prone to loosening and wear during long-term operation, affecting the normal operation and service life of the equipment; the functions of the automation control system are not perfect enough to achieve real-time monitoring and precise control of the equipment's operating status, which is not conducive to improving production efficiency and product quality.

[0024] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. To provide a clear and complete description of the technical solution, the following embodiments are selected for illustration; these embodiments are only some embodiments of the present invention; other embodiments obtained based on this application without creative effort are all within the scope of protection of the present invention.

[0025] In the following embodiments, it should be noted that the terms "upper," "lower," "left," "right," "inner," "outer," "top / bottom," etc., are all based on the orientation or positional relationship shown in the accompanying drawings and are only for the purpose of clearly describing this embodiment. They do not indicate or imply that the device or element referred to must have a specific orientation, and therefore should not be construed as a limitation of this application. At the same time, the terms "first" and "second" in the embodiments are only used for descriptive purposes and do not represent an indication or implication of relative importance.

[0026] like Figure 1-7As shown, the specific embodiment of this utility model is an automatic glue dispensing machine with a weighing sensor, which is mainly used in industrial production fields that require glue dispensing and weighing of products. It aims to provide an efficient and accurate automated device to meet the requirements of modern industrial production for product quality and production efficiency.

[0027] This automatic glue dispensing machine with a weighing sensor 7 (hereinafter referred to as "this equipment") mainly includes a frame 1, a support frame 3, a conveyor belt 4, a weighing sensor 7, and a glue dispensing assembly 2. The frame 1 serves as the supporting structure for the entire equipment, providing the mounting base for other components; the conveyor belt 4 is responsible for conveying the fixture product 11; the weighing sensor 7 is used to weigh the fixture product 11 after the glue dispensing operation is completed; and the glue dispensing assembly 2 realizes the mixing and dispensing of the glue.

[0028] The conveyor belt 4 of this application is driven by a motor and extends from the frame 1 to the support frame 3. The motor transmits power to the drive wheel of the conveyor belt 4 through a transmission device (such as a belt, chain, etc.), thereby driving the conveyor belt 4 to rotate in a cycle. The conveyor belt 4 is made of wear-resistant and non-slip rubber material to ensure that there is no slippage during the conveying of the clamp product 11, thus ensuring the stability and accuracy of the conveying.

[0029] Two positioning pin seats 402 are provided at the starting end of the frame 1 and the conveyor belt 4, and the positioning pin seats 402 are fixed to the frame 1 by bolts. Each positioning pin seat 402 is equipped with a light axis positioning pin 403, and the height of the light axis positioning pin 403 is higher than the highest point of the conveyor belt 4. When the fixture product 11 is placed on the conveyor belt 4, the light axis positioning pin 403 can initially position and align the fixture product 11, preventing it from shifting on the conveyor belt 4 and ensuring the accuracy of subsequent glue dispensing and weighing operations. Preferably, there are two light axis positioning pins 403, which can be aligned with the side of the fixture product 11. A baffle plate 401 is provided at the end of the conveyor belt 4. The baffle plate 401 can block the fixture product 11 at a specific station, so that it accurately stops in the weighing area for weighing operations.

[0030] Two photoelectric mounting plates 404 are provided on the inner side of the conveyor belt 4. The photoelectric mounting plates 404 are fixed to the frame of the conveyor belt 4. Photoelectric switches 405 are respectively installed on the photoelectric mounting plates 404. The two photoelectric switches 405 correspond to the start and end points of the travel of the clamped product 11 on the conveyor belt 4. The photoelectric switches 405 are through-beam or reflective photoelectric sensors, which can detect the position of the clamped product 11 in real time. When the clamped product 11 reaches the designated position, the photoelectric switch 405 will send a signal to control the conveyor belt 4 to stop running so that subsequent operations can be carried out.

[0031] A connecting plate 406 with an L-shaped structure is provided on the outer side of the conveyor belt 4. One end of the connecting plate 406 is connected to the frame of the conveyor belt 4 by bolts, and the other end is connected to the frame 1 by bolts. This connection method can enhance the connection stability between the conveyor belt 4 and the frame 1 and reduce vibration and noise during equipment operation.

[0032] The support frame 3 of this application is fixed to one side of the frame 1, providing installation support for weighing. A lifting mounting plate 5 is bolted to the support frame 3, and a cylinder 6 is mounted on the lifting mounting plate 5. This equipment uses a four-guide-column cylinder 6, which includes four guide shafts 601 and a cylinder body 602. A lower pad 604 is fixed to the lifting mounting plate 5. The four guide shafts 601 are evenly distributed and pass through the lower pad 604, and are fixed to the lower pad 604 by flanges. The cylinder body 602 is mounted on the lower pad 604 and located between the four guide shafts 601. An upper pad 603 is provided on the top of the guide shafts 601, and a cylinder shaft 605 extends from the top of the cylinder body 602 to abut against the upper pad 603. This structural design ensures the stability and accuracy of the cylinder 6 during the lifting process and reduces the shaking of the cylinder 6 during operation.

[0033] A weighing sensor 7 is installed on the cylinder 6. The weighing sensor 7 is a high-precision resistance strain gauge sensor, which can accurately measure the weight of the fixture product 11. A top plate 8 is installed on the weighing sensor 7. After the fixture product 11 completes the glue-pouring operation in the frame 1, it is transported to the support frame 3 by the conveyor belt 4 and finally placed on the top plate 8 of the weighing module. The total weight of the fixture product 11 is weighed by the weighing sensor 7 for quality inspection.

[0034] The dispensing assembly 2 of this application includes a mixing tank containing a stirring device driven by a motor. This device thoroughly mixes the adhesive, preventing sedimentation and solidification. A dispensing head is connected to the mixing tank via a pipe. The pipe is equipped with a control valve, which is a solenoid valve, allowing precise control of the adhesive flow rate and dispensing time. When dispensing is required, the control valve opens, allowing the adhesive to flow from the mixing tank through the pipe into the dispensing head, dispensing the fixture product 11. The mixing tank is electrically connected to a vacuum pump, which is an oil-free vacuum pump. This pump performs a vacuum treatment on the adhesive in the mixing tank before dispensing, removing air bubbles. The vacuum treatment improves the quality of the adhesive and prevents air bubbles from forming during dispensing, thus ensuring effective dispensing of the product.

[0035] The frame 1 is also equipped with an air filter 9, which is made of high-efficiency filter material and can filter dust and impurities from the air entering the equipment. This provides a good environmental condition for the stable operation of the equipment, reduces the wear and corrosion of internal components by dust and impurities, and extends the service life of the equipment.

[0036] The frame 1 is equipped with an operation box 10, which uses a touch screen control system. Operators can use the operation box 10 to monitor the equipment's operating status in real time, such as the speed of the conveyor belt 4, the lifting position of the cylinder 6, and the measurement data of the weighing sensor 7. At the same time, operators can also use the operation box 10 to control the equipment, such as starting and stopping the equipment, and adjusting the equipment's operating parameters, thus improving the convenience of operation.

[0037] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any minor modifications, equivalent substitutions and improvements made to the above embodiments based on the technical essence of the present utility model should be included within the protection scope of the technical solution of the present utility model.
