Description

Technical Field

[0001] This utility model relates to the field of mechanized assembly equipment, and in particular to a fully automated circular track assembly production line. Background Technology

[0002] In the production of toy light-up ball handles, the core assembly process involves multiple steps, including fixing the toy's base shell, assembling the positive and negative electrode plates, bending and shaping the electrode plates, assembling the button glue particles and circuit board, cutting and soldering the positive and negative connecting wires, soldering the double-wire copper lamp, testing the power-on function, and screening and rejecting defective products. Currently, the industry still largely relies on traditional manual operation for the production of such products, which presents significant technical bottlenecks and production pain points, specifically in the following four aspects: First, manual operation has low precision, making it difficult to guarantee product yield.

[0003] During manual assembly, the assembly deviation rate of core components remains high. For example, positioning adhesive particles need to be manually placed on the button assembly positions of the toy's bottom shell. Affected by hand stability and visual judgment errors, the deviation rate can reach 5%-8%, directly causing the button switches on the subsequent circuit board to malfunction. The bending process of positive and negative electrode sheets relies on manual labor with simple tools. The bending direction is inconsistent, and problems such as electrode sheet breakage or incorrect bending angle (required to be 90±1) are prone to occur. The electrode sheets need to be readjusted or replaced during subsequent soldering, which increases labor costs. When manually separating circuit boards, the breakage rate exceeds 3% due to uneven force or inaccurate positioning. Furthermore, burrs are easily generated on the edges of the circuit boards after separation, affecting their compatibility with the toy's bottom shell. In addition, when manually soldering the positive and negative electrode connecting wires and copper wire lamps, defects such as bridging, cold solder joints, and missing solder joints are prone to occur. The soldering yield rate is only maintained at 85%-90%, and the rework rate of defective products is high, which seriously restricts the overall production efficiency.

[0004] Second, low production efficiency makes it impossible to meet mass production demands.

[0005] Each process is operated independently by manual labor, lacking continuous production coordination, resulting in a lengthy overall cycle time. Specifically, the manual board separation efficiency is only 30pcs / min, and the complete assembly cycle of a single product from bottom shell loading to finished product output takes as long as 15 seconds, with an average daily capacity of less than 3,600 pieces, far from meeting the mass production demand of ≥5,000 pieces per day in the downstream market; material transfer between processes relies on manual handling, which is not only time-consuming (each transfer takes 2-3 minutes) but also prone to damage to semi-finished products due to collisions; the power-on testing process requires manual installation of batteries, pressing of switches, and visual inspection of copper wire lamp brightness, with a single person only able to test 80-120 pieces per hour, becoming a "bottleneck" process on the production line, often resulting in "flow interruptions" where materials are piling up at the front end and waiting for materials at the back end, seriously affecting production continuity.

[0006] Third, high labor costs and high operational risks do not meet the needs of modern production.

[0007] A traditional manual production line requires 3-4 operators, each responsible for loading the base shell, assembling the electrode sheets, welding, testing, and screening. Based on current industry labor costs, annual labor expenses exceed 150,000 yuan, significantly increasing production costs. During the power-on testing phase, operators must stare directly at the lit double-wire copper lamps for extended periods (6-8 hours per day), and the strong light can easily cause visual fatigue and even vision damage. When manually screening good products, differences in concentration and subjective judgment can easily lead to situations where "good products are misjudged as defective products" (misjudgment rate of about 2%) or "defective products are missed and enter the market" (missed judgment rate of about 3%). The former results in material waste, while the latter may lead to customer complaints and damage the company's brand image.

[0008] Fourth, existing equipment has poor compatibility and high modification costs.

[0009] While a few automated assembly machines exist on the market for electronic components or standard mechanical parts, none can accommodate the irregular contours of toy light-up ball handles (such as the curved bottom shell or the special angle of the copper wire lamp extension). If companies modify existing equipment to meet production needs, they must customize special fixtures, adjust the transmission structure and control program, with modification costs reaching 30,000-50,000 yuan per unit. Moreover, the modified equipment can only be used for a single product model. As the demand for personalization in the toy market increases, companies need to frequently change product models. Frequent equipment modifications not only further increase costs but also lead to production interruptions, making it difficult to adapt to multi-category, small-batch production models.

[0010] In summary, the current production process of toy light-up ball handles lacks a set of production equipment that integrates full-process automation, high precision, and high compatibility. There is an urgent need to design a circular track-type continuous production line, which can solve the problems of low precision, poor efficiency, high cost, and insufficient equipment compatibility of manual operation through standardized workstation layout and precise control, and promote the upgrading of the industry's production mode towards automation and large scale.

Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention.

[0032] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0033] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0034] like Figure 1-33 As shown, the present invention provides the following implementation examples.

[0035] Example 1: A fully automatic circular track assembly production line, including a positioning frame 1, a circular track 2, several jig moving units 3, a feeding station 4, an electrode sheet assembly station 5, an electrode sheet bending station 6, a button assembly station 7, a connecting wire welding station 8, a copper wire lamp welding station 9, a power-on testing station 10, and a good product screening station 11. The annular track 2 is fixedly installed on the positioning frame 1. Several fixture moving units 3 are evenly distributed and slidably installed on the annular track 2. Each fixture moving unit 3 includes a slider 31, a bottom shell fixture 32, and an alignment component 33. The slider 31 is slidably fitted with the annular track 2. The bottom shell fixture 32 is detachably installed on the slider 31. The bottom shell fixture 32 has a cavity for fixing the toy bottom shell 12. A first transverse guide rail 22 is fixedly installed on the slider 31. Multiple alignment components 33 are provided, and each alignment component 33 is installed one-to-one between the side of the slider 31 and the positioning frame 1. The feeding station 4, electrode sheet assembly station 5, electrode sheet bending station 6, button assembly station 7, connecting wire welding station 8, copper wire lamp welding station 9, power-on testing station 10, and good product screening station 11 are sequentially arranged on the positioning frame 1 along the circular track 2. The principle is as follows: the alignment component 33 allows the slider 31 to automatically align itself when sliding to each station, ensuring the conveying accuracy of each station during assembly, welding, and testing. The ring track 2 allows the fixture moving unit 3 to perform automatic cyclic conveying operations on the positioning frame 1, realizing automated production assembly. The feeding station 4, electrode sheet assembly station 5, electrode sheet bending station 6, button assembly station 7, connecting wire welding station 8, copper wire lamp welding station 9, power-on testing station 10, and good product screening station 11 are respectively used to assemble on the toy base shell 12, realizing automated operation.

[0036] Furthermore: the alignment component 33 includes a positioning bracket 331, a first displacement cylinder 332, a second rotating shaft 333, a cylinder connecting rod 334, and an alignment connecting rod 335; the positioning bracket 331 is fixedly installed on the positioning frame 1, the first displacement cylinder 332 is rotatably mounted on the positioning bracket 331, the second rotating shaft 333 is rotatably mounted above the positioning frame 1, the cylinder connecting rod 334 and the alignment connecting rod 335 are both fixedly mounted on the second rotating shaft 333, the end of the first displacement cylinder 332 is rotatably mounted on the cylinder connecting rod 334, and the first displacement cylinder 332 drives the second rotating shaft 333 to rotate through the cylinder connecting rod 334; The outer end of the alignment connecting rod 335 is fixedly installed with an alignment block 336, and an alignment notch 337 is formed on the slider 31. When the second rotating shaft 333 rotates, it drives the alignment block 336 to be inserted into the alignment notch 337 with a gap fit. The alignment block 336 on the alignment connecting rod 335 can be inserted into the alignment notch 337 of the slider 31 to move and limit the movement of the first displacement cylinder 332 to drive the second rotating shaft 333 to rotate, thereby ensuring the accurate positioning of the slider 31 when it moves to each station.

[0037] Furthermore: The loading station 4 includes a base plate 41, a first drive mechanism 42 and a first pneumatic finger 43. The base plate 41 is fixedly installed on the positioning frame 1. The toy bottom shell 12 is clamped and installed in the first pneumatic finger 43. The first drive mechanism 42 clamps the toy bottom shell 12 through the first pneumatic finger 43 and transports it into the bottom shell fixture 32. The first drive mechanism 42 enables the toy base shell 12 on the first pneumatic finger 43 to align with the base shell fixture 32, thereby realizing automatic feeding operation on the base shell fixture 32 and providing the possibility of automation for the production of the handle of the toy light-up ball.

[0038] Furthermore: The electrode assembly station 5 includes two electrode assembly mechanisms 51, and the toy bottom shell 12 is provided with two electrode insertion positions 121, with the two electrode assembly mechanisms 51 corresponding to the two electrode insertion positions 121 of the toy bottom shell 12 respectively. The electrode assembly mechanism 51 includes a support platform 511, a first conveying mechanism 513, a first rotating mechanism 514, and a second pneumatic finger 515. The first conveying mechanism 513 is fixedly installed on the upper end of the support platform 511. The first conveying mechanism 513 drives the first rotating mechanism 514 to move above the toy bottom shell 12. The first rotating mechanism 514 drives the second pneumatic finger 515 to rotate. Two electrode assembly mechanisms 51 are used to insert the positive and negative electrode plates into the two electrode plate insertion positions 121 of the toy's bottom shell 12. The first conveying mechanism 513 and the first rotating mechanism 514 achieve precise positioning when the second pneumatic finger 515 is inserted into the electrode plate insertion position 121, ensuring accuracy during batch assembly, avoiding manual assembly by workers, and greatly improving production efficiency.

[0039] Furthermore: the electrode bending station 6 includes a bending unit 61, which is fixedly installed on the positioning frame 1 and is located above the toy bottom shell 12. The positive electrode 25 and the negative electrode 26 are respectively inserted and fitted into the two electrode insertion positions 121 of the toy bottom shell 12. When the bending unit 61 is working, it bends the positive electrode 25 and the negative electrode 26. By using the bending unit 61 to press down the upper ends of the positive electrode sheet 25 and the negative electrode sheet 26, a stable bending effect is achieved. The bending direction can be kept consistent, and they will not be easily broken, thus ensuring the quality and efficiency of production and assembly.

[0040] Furthermore: the bending unit 61 is provided with two pressing mechanisms 614, and a width adjuster 615 is fixedly installed between the two pressing mechanisms 614.

[0041] Furthermore: the button assembly station 7 includes a granule feeder 71 and a circuit board feeder 72. A button assembly position 27 is formed inside the toy's bottom shell 12. The granule feeder 71 is provided with multiple positioning granules 14. The granule feeder 71 feeds the positioning granules 14 one by one into the button assembly position 27. The circuit board feeder 72 is provided with multiple circuit boards. A button switch 28 is embedded on the bottom side of a single circuit board 16. The circuit board feeder 72 feeds the single circuit board 16 one by one into the button assembly position 27 and allows the button switch 28 to press down the positioning granules 14 to complete the feeding and assembly.

The following structure is optimized based on embodiment one: 1. Optimization of loading station 4: Rubber pads with a thickness of 1mm and a hardness of 50 Shore A are added to the inner side of the semi-circular groove 431 and semi-circular protrusion 432 of the first pneumatic finger 43 to increase friction and prevent slippage caused by anti-slip texture during clamping, with clamping stability ≥99.8%.

This reduces the friction wear between the anti-slip texture and the cavity and extends the service life of the fixture to more than 100,000 times.

[0086] 3. Button assembly optimization: A flexible protrusion is added to the inner side of the fifth pneumatic finger 728 of the circuit board loading machine 72.

The positioning deviation is ≤0.1mm.

[0087] 4. Welding optimization: The first welding head 8243 and the second welding head 8342 of the connecting wire welding station 8 are coated with an anti-stick coating made of ceramic to prevent solder dross from sticking to the welding head during welding, reduce welding defects, and maintain a welding yield of ≥99%.

The various processes are well compatible, and there are no jamming or defects caused by the anti-slip textures. The production efficiency is consistent with that of regular products.
