[0035] The following is a further description of the embodiments of the present invention in conjunction with the accompanying drawings:

[0036] As shown in the figure, an automatic assembly equipment includes a frame 1 and a manipulator 2 installed on the frame 1, the frame 1 is provided with a loading mechanism 3 for transporting parts to predetermined positions, a gluing mechanism 4 for gluing some parts, a screw tightening mechanism 5 for screwing the assembled semi-finished materials and the remaining parts to form finished materials, and a unloading mechanism 6 for outputting the finished materials; the manipulator 2 has a first state of transferring parts from the loading mechanism 3 to the gluing mechanism 4, a second state of transferring semi-finished materials from the gluing mechanism 4 to the screw tightening mechanism 5, and a third state of transferring finished materials from the screw tightening mechanism 5 to the unloading mechanism 6, the manipulator 2 can assemble some of the glued parts into the semi-finished materials at the gluing mechanism 4 between the first state and the second state, and can screw the semi-finished materials with the remaining parts at the screw tightening mechanism 5 between the second state and the third state. The remaining parts are assembled; in this technical solution, employees place parts (such as upper shell, PCBA board, lower shell) on the loading mechanism, the loading mechanism moves the parts to the pre-grabbing position of the robot, and the robot grabs some parts (PCBA board, lower shell) to the dispensing mechanism. The dispensing mechanism automatically applies heat dissipation glue on some parts according to the set program. After the gluing is completed, the robot preliminarily assembles some parts (PCBA board, lower shell) into semi-finished products. After the assembly is completed, it is grabbed onto the screw tightening mechanism. The robot goes to the loading mechanism to clamp the remaining parts (upper shell) and transfers them to the screw tightening mechanism for assembly with the semi-finished products. After the assembly is completed, the screw tightening mechanism tightens the 4 screw holes of the semi-finished product and records its screw tightening data. After the screw tightening is completed, the robot transfers the finished product to the unloading mechanism and transfers it to the next process to continue production; it has the advantages of high degree of automation and high product qualification rate.

[0037] Specifically, this automated assembly equipment achieves fully automated production, from part loading to finished product unloading, through the coordinated operation of a robot 2, a loading mechanism 3, a glue dispensing mechanism 4, a screw tightening mechanism 5, and a discharge mechanism 6. This significantly improves production efficiency, reduces manual intervention, lowers production costs, and enhances reliability and safety. During this process, the robot 2 assumes multiple states, enabling precise transfer of parts and semi-finished materials between different processes: at the glue dispensing mechanism 4, the robot accurately assembles the glued parts into semi-finished materials; at the screw tightening mechanism 5, the robot precisely assembles the semi-finished materials with the remaining parts to form the finished product. This precise assembly ensures product quality and consistency and enables efficient integration of different processes. It is also understood that additional processing equipment (either as a supplement to or as an alternative to glue dispensing and screw tightening) can be added to meet different product or production needs, providing high flexibility and adjustability.

[0038] It should be understood that the MES manufacturing execution system can be associated with this automatic assembly equipment. The MES can obtain key data in the tightening process in real time, such as torque value, angle, and tightening time, and store and associate it with specific products or batches, ensuring the integrity, accuracy, and traceability of the data. It can also monitor the production status of the production line in real time, optimize resource allocation such as material distribution, staffing, and equipment utilization, and improve the overall efficiency and balance rate of the production line. In addition, the data indexing and query mechanism of the MES allows users to quickly retrieve and query data for specific time periods, specific products, or specific processes. Through flexible query conditions, users can obtain the required traceability data, analyze and compare it, to facilitate problem troubleshooting, quality traceability, and compliance verification.

[0039] The remaining parts of the manipulator 2 when it is between the second state and the third state are grabbed and transferred from the loading mechanism 3, which can also reduce the production downtime caused by waiting for parts.

[0040] The dispensing mechanism 4 in this embodiment includes:

[0041] A first platform 41, which is mounted on the frame 1 and has first brackets 45 mounted on both sides thereof;

[0042] A first driving member 42 is mounted on the first platform 41 and has a first mold 43 at its output end for placing parts;

[0043] A second driving member 44 is mounted on the first bracket 45 and has an output end provided with a first mounting plate 46 driven to move along the X-axis direction;

[0044] A third driving member 47 is mounted on the first mounting plate 46 and has an output end provided with a second mounting plate 48 driven to move along the Z-axis direction;

[0045] A fourth driving member 49, which is mounted on the second mounting plate 48 and has a glue dispensing barrel 40 mounted on its output end;

[0046] The first mold 43 is driven by the first driving member 42 to move along the Y-axis direction. The glue dispensing barrel is a prior art. Generally, the glue liquid is discharged from the glue outlet at the lower end of the glue dispensing barrel by applying pressure to the barrel. This is a purchased part and will not be described in detail here. Those skilled in the art should understand the meaning of the X-axis, Y-axis, and Z-axis. For example, they are perpendicular to each other to form a rectangular coordinate system. Among them, the X-axis direction can be the direction of the long side of the frame, the Y-axis can be the direction of the short side of the frame or the feed direction, and the Z-axis direction can be the height direction. This solution realizes the dispensing of some parts in various directions through the coordinated work of the first driving member 42, the second driving member 44, the third driving member 47 and the fourth driving member 49. This enables the dispensing process to be accurately aligned with the predetermined position on the part, ensuring the accuracy and consistency of the dispensing.

[0047] In addition, the first driving member, the second driving member and the third driving member adopt linear sliding servo modules, and the fourth driving member adopts a cylinder. The above driving members are all purchased parts, which have the advantages of low cost and good working stability. In addition, other power elements such as cylinders or linear motors can also be used.

[0048] The first drive member can move the material on the first mold in the Y-axis direction, while the second and third drive members can move the dispensing barrel in the X-axis and Z-axis directions. These three-directional movements can bring the dispensing barrel and the material closer together and align them, thereby completing the application of thermal adhesive. The fourth drive member can also move the dispensing barrel in the Z-axis direction to accommodate products of different heights.

[0049] The screw tightening mechanism 5 comprises:

[0050] A second platform 50, which is mounted on the frame 1 and has second brackets 51 mounted on both sides thereof;

[0051] A fifth driving member 53, which is mounted on the second platform 50 and has a second mold 54 at its output end for placing materials;

[0052] a sixth driving member 55 , which is mounted on the second bracket 51 and has an output end provided with a third mounting plate 56 driven along the X-axis direction;

[0053] a seventh driving member 57, which is mounted on the third mounting plate 56 and has an output end provided with a fourth mounting plate 58 driven along the Z-axis direction;

[0054] An eighth driving member 59, which is mounted on the upper end of the fourth mounting plate 58;

[0055] A plurality of movable seats 71 slidably mounted on the fourth mounting plate 58 and connected to the output end of the eighth driving member 59 ;

[0056] A tightening assembly 7, which is mounted vertically downward on the movable seat 71;

[0057] The second mold is driven by the fifth driving member 53 to move along the Y-axis direction, and the movable seat is driven by the eighth driving member 59 to move along the Z-axis direction; the fifth driving member, the sixth driving member and the seventh driving member adopt a linear sliding servo module, and the eighth driving member adopts a cylinder. The above driving members are all purchased parts and have the advantages of low cost and good working stability. In addition, other power elements such as cylinders or linear motors can also be used.

[0058] The fifth driving member can drive the material on the second mold to move in the Y-axis direction, and the sixth driving member and the seventh driving member can drive the tightening assembly to move in the X-axis and Z-axis directions. The movement in three directions can make the tightening assembly and the material close to and align with each other, thereby completing the screw tightening work. The eighth driving member can also drive the dispensing barrel to move in the Z-axis direction, which can adapt to products of different heights; through the coordinated work of the fifth driving member 53, the sixth driving member 55, the seventh driving member 57 and the eighth driving member 59, the precise movement of the assembled semi-finished material and the remaining parts in various directions is realized; this enables the tightening process to be carried out accurately, ensures the accuracy and consistency of screw tightening, and thus improves the quality and stability of the product.

[0059] The tightening assembly includes a screw machine 72 mounted on a high-positioned movable base 71 and a feed tube 73 mounted on a low-positioned movable base 71. The feed tube 73 is provided with a guide channel 74 through which the bottom end of the screw machine 72 passes, and a feed tube 75 for the screw to enter. The guide channel 74 is arranged straight and communicates with the inclined feed tube 75. The guide channel 74 and the feed tube 75 form a Y-shape when combined. The screw is fed into a loading area (not shown) by a vibrating feed tray (not shown) and simultaneously fed into the feed tube by a carrier gas source (not shown). This structure is prior art and will not be described in detail here. The screw enters the various screw holes in the upper shell through the feed tube, and then the screw machine tightens the screw through the guide channel. The terms "high position" and "low position" refer to the relative positional relationship between the two movable bases 71. The design of the feed tube allows the screw to smoothly enter the guide channel 74 from the feed tube 75 and be accurately guided to the bottom end of the screw machine 72, thereby achieving an efficient and stable feeding process. The straight guide channel 74 of the feed tube 73 ensures stable and accurate screw feeding. Once the screw is fed to the bottom end of the screw driver 72, it accurately grasps the screw and tightens it. The straight guide channel 74 and the angled insertion of the feed channel 75 ensure smooth screw feeding, reducing the risk of jamming and clogging.

[0060] The manipulator 2 is equipped with a gripper 21, which utilizes either an electric cylinder gripper or a finger cylinder. These grippers offer excellent practicality. Specifically, they offer high precision and stability, can accommodate workpieces of varying shapes, sizes, and weights, and provide rapid response. Furthermore, the manipulator and its gripper (e.g., an electric cylinder gripper or finger cylinder) can better handle hazardous environments or assembly processes.

[0061] The feeding mechanism 3 includes:

[0062] a ninth driving member 31 , mounted on the frame 1 ;

[0063] a tray 32 connected to the output end of the ninth driving member 31 and arranged horizontally;

[0064] The tray 32 is driven by the ninth drive member 31 to a predetermined position (e.g., along the Y-axis) for grasping by the manipulator 2. Material is placed on the tray, which is then driven by the ninth drive member to move the material to the manipulator's pre-grab position. The loading mechanism 3, via the ninth drive member 31, drives the tray 32, achieving automated material loading. This eliminates the need for human intervention, reduces labor costs, and improves production efficiency, making the entire production process smoother and more efficient. The tray 32 is driven by the ninth drive member 31 to a predetermined position for grasping by the manipulator 2. This ensures precise positioning of the material during grasping, guaranteeing accurate and stable grasping.

[0065] The unloading mechanism 6 adopts a conveyor belt mechanism, and can also adopt a sliding servo module or a ball screw mechanism; the conveyor belt mechanism can continuously and smoothly transport parts while ensuring a simple structure, and the cost is controllable; the latter two have the characteristics of high precision, fast response, and strong load-bearing capacity.

[0066] The cylinder in this article can be a transplanting cylinder, which has the advantages of improving the degree of automation and production efficiency, improving production accuracy and quality, strong adaptability and low maintenance cost, and improving the flexibility and scalability of the production line.
