Description

Technical Field

[0002] In the encapsulation production process of electronic products, conveyor lines play an irreplaceable role in connecting the assembly line and encapsulation equipment, as well as in transporting products between the encapsulation equipment and the docking station. They are an indispensable and important component in the automated encapsulation (sealing) production of electronic products. Commonly used conveyor mechanisms include chain conveyors, belt conveyors, roller conveyors, and flexible chain conveyors.

[0003] With the rapid development of electronic technology, electronic products are becoming increasingly feature-rich, while simultaneously demanding higher standards for cost control and quality, especially for automated glue-filling production processes. Existing production line technologies struggle to simultaneously meet the following requirements: 1. Electronic products come in diverse styles and sizes, yet all need to be produced on the same line; 2. Traditional production methods involve creating a matching carrier for each product, which then circulates on the conveyor line. To save costs, carriers cannot be used; instead, products must be placed directly on the conveyor line without being scratched during transport. Furthermore, static electricity generated during transport must be prevented from damaging the electronic products; 3. The glue-filling process requires real-time weighing of the products on the conveyor line to ensure accurate glue application. Utility Model Content

The conveyor can also adjust the position of the baffles to form different conveying widths, thereby meeting the conveying and circulation of electronic products of various sizes. In order to prevent electronic products from being damaged by friction and scratches and static electricity generated when they are flowing on the conveyor line, the front adjustable baffle 309 and the rear adjustable baffle 310 that come into contact with the products are made of special anti-static plastic material. The anti-static plastic material has low hardness and a smooth surface, which effectively prevents scratches on electronic products. At the same time, it has anti-static function and will not damage electronic products due to static electricity.

[0051] like Figure 4As shown, the lifting and weighing device 4 includes a lifting cylinder 41, a weighing device base 42, a linear bearing 43, a guide shaft 44, a fixed pressure block 45, a lifting plate 46, and an electronic scale 47. The lifting cylinder 41 is fixed at the center of the weighing device base 42. The piston rod of the lifting cylinder 41 is fixedly connected to the center of the lifting plate 46. Multiple sets of linear bearings 43 and guide shafts 44 are evenly arranged around the lifting cylinder 41 and are respectively connected to the lifting plate 46 and the weighing device base 42. Each set of guide shafts 44 passes through and slides with the linear bearing 43, providing guidance and positioning for the vertical reciprocating movement of the lifting plate 46. The electronic scale 47 is fixedly connected to the upper part of the lifting plate 46 through multiple fixed pressure blocks 45. When the lifting cylinder 41 is retracted, the top surface of the electronic scale 47 is lower than the plane of the conveyor chain plate.

[0052] The working process of the adjustable-width and anti-static conveyor line in this embodiment is as follows: Electronic products transferred from the previous station flow into the left side of the flexible chain conveyor line 2. The drive motor 27 runs, driving the transmission shaft 28 to rotate, which drives the front conveyor chain plate 23 and the rear conveyor chain plate 24 to run synchronously, causing the electronic products to move from left to right on the flexible chain conveyor line 2. When the sensor 9 detects the electronic product, the blocking cylinder 6 rises, the buffer blocking block 7 stops the electronic product, and then the flexible chain conveyor line 2 stops running. At this time, the preparation work for feeding the electronic product is completed, and the production process of the current equipment station can begin. If the current station is a glue-pouring equipment, the following working process will also be performed: the lifting cylinder 41 drives the piston rod to drive the lifting plate 46 and the electronic scale 47 to rise, and then the electronic scale 47... The lifting cylinder 41 is lifted until it is completely detached from the contact of the flexible chain conveyor 2. After the lifting cylinder 41 reaches its upper limit, it stops. The electronic scale 47 reads and records the weight data of the electronic product. Then, the dispensing machine starts dispensing the electronic product. After dispensing, the electronic scale 47 weighs the dispensing electronic product, reads and records the weight data. The dispensing machine control system calculates the amount of dispensing for the electronic product by subtracting the two weight data and determines whether it meets the set requirements. After the above actions are completed, the lifting cylinder 41 descends and resets, and the dispensing electronic product is placed back on the flexible chain conveyor 2. The blocking cylinder 6 drives the buffer blocking block 7 to descend, and then the flexible chain conveyor 2 starts running, transporting the electronic product to the next station to the right.

[0053] When the production line needs to switch to producing a different size electronic product, simply loosen the fixing bolts of the front adjustable baffle 309 or the rear adjustable baffle 310, then slide the front adjustable baffle 309 or the rear adjustable baffle 310 to the previously calibrated scale position of the current electronic product, referring to the first front scale 302, the second front scale 311 or the first rear scale 304, and the second rear scale 313. Then tighten the fixing bolts of the adjustable baffle 309 or the rear adjustable baffle 310. By following the above steps, the width of the conveyor line can be quickly adjusted, enabling rapid changeover production when the production line changes product models, thus improving production efficiency.

The rear adjustable baffle has sliding grooves at both ends, which slide in cooperation with the first and second rear guide rails respectively, and are connected to the rear base through bolts.

4. A conveyor line as described in claim 3, characterized in that: The front base is fixedly provided with a first front scale and a second front scale at both ends, which are used to mark the position when adjusting the front adjustable baffle; the rear base is fixedly provided with a first rear scale and a second rear scale at both ends, which are used to mark the position when adjusting the rear adjustable baffle.

5. A conveyor line as described in claim 1, characterized in that: The lifting and weighing device includes a lifting cylinder, a weighing device base, linear bearings, guide shafts, fixed pressure blocks, a lifting plate, and an electronic scale. The body of the lifting cylinder is fixed at the center of the weighing device base, and the piston rod of the lifting cylinder is connected to the center of the lifting plate. At least two sets of linear bearings and guide shafts are provided, evenly distributed around the lifting cylinder, and connected to the lifting plate and the weighing device base respectively. Each set of guide shafts passes through and slides with the linear bearing, providing guidance and positioning for the vertical reciprocating movement of the lifting plate. The electronic scale is fixedly connected to the upper part of the lifting plate through at least two fixed pressure blocks.

6. A conveyor line as described in claim 1, characterized in that: The outer surface of the flexible chain conveyor is provided with an anti-static layer.

7. A conveyor line as described in claim 6, characterized in that: The antistatic layer is made of plastic.

8. A conveyor line as described in claim 1, characterized in that: The stop positioning assembly includes a buffer block, a blocking cylinder, and a cylinder fixing plate, which are connected in sequence and fixedly connected to the base plate.

9. A conveyor line as described in claim 1, characterized in that: The sensing component includes a sensor bracket and a sensor, with the sensor fixed to one side of the width adjustment device via the sensor bracket.
