[0002] In automated assembly lines for electronic components and small precision parts, the tray loading process is a core step in material handling, and its efficiency and accuracy directly affect the overall production line's capacity and product yield. Currently, many production lines in the industry still rely on manual tray loading. Operators must move the trays one by one to the conveyor station, which is not only labor-intensive and inefficient in meeting the demands of high-speed production lines, but also prone to material misalignment and damage due to human error, and may even introduce dust and other contaminants, adversely affecting the quality of precision products.

[0003] However, existing automated tray loading equipment also has some shortcomings. For example, most of the equipment is a single-module structure, which makes it difficult to support the material supply of high-speed production lines. Furthermore, tray material distribution often adopts a simple lifting or pushing structure, which can easily lead to problems such as tray stacking and jamming, and incomplete separation of individual trays during actual operation, affecting the stability of material loading.

[0020] See attached document Figure 1-7 A tray loading device includes a base 12 and a protective cover 13. The protective cover 13 is provided with two sets of loading assembly modules. Each loading assembly module includes two tray loading conveyor components 1 arranged in parallel. The front end of each tray loading conveyor component 1 is provided with a carrier misalignment receiving mechanism 2 and an assembly robot 3. A vision inspection module A4 is provided between the assembly robot 3 and the carrier misalignment receiving mechanism 2. The tray loading conveyor component 1 includes a tray hopper 6, a material distribution conveyor line 7 and a lifting mechanism 8 arranged from top to bottom. One end of the tray hopper 6 is provided with a protective light grid 5, and one end of the material distribution conveyor line 7 is connected to the carrier misalignment receiving mechanism 2.

[0021] The tray loading equipment uses a base 12 as its support. The base 12 is equipped with casters with adjustable feet at the bottom, which ensures both ease of movement and stability. The base 12 has a built-in lead screw slide 202 and integrates core components such as pneumatic components and electrical control modules to provide power and signal control support for each actuator. A protective cover 13 is installed on top of the base 12. The protective cover 13 is detachably connected to the base 12 by a hinge and a buckle, which not only provides safety protection and dust protection but also facilitates future equipment maintenance. The operating surface of the protective cover 13 integrates an operation panel and a display window, which can realize parameter setting, equipment start and stop control, and real-time display of operating status and detection data.

[0022] The protective cover 13 is equipped with two independent feeding and assembly modules. The two modules work in parallel to improve production capacity. Each feeding and assembly module includes two parallel tray feeding and conveying components 1. The front end of the tray feeding and conveying components 1 is connected to the carrier misalignment receiving mechanism 2 and the assembly robot 3 in sequence along the material flow direction. The assembly robot 3 and the carrier misalignment receiving mechanism 2 are matched one-to-one. Above the docking area between the assembly robot 3 and the carrier misalignment receiving mechanism 2, a vision inspection module A4 is also provided for the accuracy and status detection after material conveying.

[0023] Each tray feeding and conveying assembly 1 adopts a layered structure of "upper layer storage + middle layer distribution and conveying + lower layer lifting", consisting of tray hopper 6, distribution conveyor line 7 and lifting mechanism 8 from top to bottom: Tray hopper 6: Erected above the frame of the material distribution conveyor line 7, and fixedly connected to the material distribution conveyor line 7 by bolts, its structure includes two mirror baffles 602 fixed on the support platform 601, forming a space for accommodating the tray stack; a fixed partition 603 is provided at the rear end of the baffle 602 to limit the rear end of the tray stack, and an opening and closing plate 604 is provided at the front end. The opening and closing plate 604 is hinged to the baffle 602 by a telescopic cylinder 605. When the telescopic cylinder 605 is vented, the opening and closing plate 604 can close inward to limit the tray stack laterally, or the opening and closing plate 604 can open outward to facilitate material replenishment; multiple infrared sensors 606 are also arranged on the opening and closing plate 604 to detect the stacking height and material status of the trays in the hopper in real time, and automatically issue a material replenishment prompt signal when the material is insufficient; Material distribution auxiliary mechanism: An upper material distribution mechanism 10 is provided at one end of the support platform 601 near the partition 603. It is a cylinder-driven pallet structure used to support the upper tray stack during material distribution, so as to achieve single tray separation. Two blocking mechanisms 9 are symmetrically provided at the lower end of the support platform 601. They are cylinder-driven blocking block structures located at the front and rear ends of the lifting mechanism 8, respectively. They can limit the lifting position of the tray by extending or retracting, in coordination with the material distribution action. A lower material distribution mechanism 11 is also provided on the outside of one of the blocking mechanisms 9. It is also a cylinder-driven pallet structure used to accurately position a single tray on the material distribution conveyor line 7 to ensure the subsequent conveying accuracy. Lifting mechanism 8: Composed of lifting frame 801 and linear electric cylinder 802. Linear electric cylinder 802 is fixed to the upper end of machine base 12 through support base. Lifting frame 801 is connected to the output slider flange of linear electric cylinder 802. Linear electric cylinder 802 can drive lifting frame 801 to rise and fall in the vertical direction, thereby driving the tray stack in tray hopper 6 to rise and fall, and cooperate with upper material distribution mechanism 10 to complete single tray material distribution. Material sorting conveyor line 7: The lower end is fixed to the upper end of the machine base 12 through multiple support bases, and its conveying end is connected to the carrier conveyor line 201 of the carrier misalignment receiving mechanism 2; the material sorting conveyor line 7 adopts a belt conveyor structure, which can stably transport the individual trays after sorting to the receiving station.

[0024] One end of the tray hopper 6 is also equipped with a protective light grid 5. This light grid is linked to the equipment emergency stop system. When the operator accidentally touches the area of ​​the hopper and blocks the light grid, the equipment will stop immediately to ensure operational safety.

[0025] The carrier misalignment receiving mechanism 2 includes a carrier conveyor line 201 and a lead screw slide 202: the lead screw slide 202 is embedded inside the base 12, and its slider is fixedly connected to the bottom of the carrier conveyor line 201; the carrier conveyor line 201 is a belt conveyor structure used to carry trays and convey them to the assembly station. Through the horizontal drive of the lead screw slide 202, the carrier conveyor line 201 can achieve misalignment movement, and can sequentially connect to the material distribution conveyor line 7 of two parallel tray feeding conveyor components 1 in the same feeding assembly module, continuously receiving materials from two trays, improving the flexibility and efficiency of receiving materials.

[0026] The assembly robot 3 and the carrier misalignment receiving mechanism 2 are set up one-to-one. The main body of the robot is a four-axis robot 301, which is fixed to the bracket at the upper end of the base 12 by the base bolts. The end effector of the four-axis robot 301 is connected to the material picking module 302 through a quick-change connector, and can be replaced with a vacuum suction cup or gripper structure according to the material type to pick up the material in the tray. The material picking module 302 also integrates a vision inspection module B303, which can perform secondary inspection on the position and appearance of the material before picking up the material to ensure that the picked up material meets the assembly requirements.

[0027] The specific workflow is as follows: Material preparation: The operator places the stacked trays between the two baffles 602 of the tray hopper 6. The telescopic cylinder 605 drives the opening and closing plate 604 to close, which limits the side of the tray stack. After the infrared sensor 606 detects that there is material in the hopper, the equipment enters the standby state.

[0028] Material sorting action: The linear electric cylinder 802 of the lifting mechanism 8 drives the lifting frame 801 to rise, which in turn raises the tray stack to the set height; the upper material sorting mechanism 10 extends to support the upper tray stack, and the lifting frame 801 descends slightly, so that the bottom single tray falls into the material sorting conveyor line 7; the lower material sorting mechanism 11 operates to accurately position the single tray.

[0029] Conveying and Inspection: The material conveyor line 7 conveys a single tray to the docking position. The vision inspection module A4 inspects the positional accuracy of the tray and the presence or absence of materials. After the inspection is qualified, the lead screw slide 202 drives the carrier conveyor line 201 to move to the docking position, and the tray is conveyed onto the carrier conveyor line 201.

[0030] Material handling and transfer: The four-axis robot 301 of the assembly robot 3 drives the material handling module 302 to move above the tray, and the vision inspection module B303 performs a secondary inspection of the material; after passing the inspection, the material handling module 302 grabs the material and transports it to the subsequent assembly station.

[0031] Continuous feeding: Another tray feeding and conveying component 1 in the same feeding assembly module simultaneously completes the material distribution and conveying. The carrier conveyor line 201 moves in a staggered manner through the lead screw slide 202 to connect with the material distribution conveyor line 7 of this component to achieve continuous material receiving. When the tray in the hopper is insufficient, the infrared sensor 606 sends a material replenishment signal to remind the operator to replenish the material. The assembled tray is output to the next process through the side of the equipment.

[0032] Safety protection: During equipment operation, the protective light curtain 5 continuously monitors the hopper area. If personnel accidentally touch it, it will immediately trigger an emergency stop to ensure operational safety.

[0033] The above-described embodiments are merely illustrative of certain implementations of this utility model, and their descriptions are relatively specific and detailed. However, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
