[0037] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0038] It should be noted that the directions in the diagram are described using the X, Y, and Z coordinate system, where X, Y, and Z represent three directions of motion.

[0039] Example 1:

[0040] refer to Figure 3 and Figure 4 The loading and transfer equipment of the automatic assembly line for the inner and outer frames of the aluminum inspection port includes a beam frame 10; a Y-axis motion mechanism is installed on the top of the beam frame 10.

[0041] The Y-axis motion mechanism includes a track arm 101, a drive wheel 102, and a drive motor 104. The track arm 101 is fixed on both sides of the top of the beam frame 10. The drive wheel 102 is installed at both ends of the inner side of the track arm 101. The drive wheel 102 has a conveyor belt 103. A transverse arm 30 is slidably connected to the track arm 101. The bottom end of the transverse arm 30 is fixed to the conveyor belt 103. The drive motor 104 is located at the tail end of the beam frame 10. A linkage shaft 105 is installed at the output end of the drive motor 104. Both ends of the linkage shaft 105 are fixed inside the drive wheel 102. A first slider 301 is fixed at the bottom of the transverse arm 30. The first slider 301 is slidably connected to the track arm 101.

[0042] In the above scheme, by starting the drive motor 104, the power output of the drive motor 104 is transmitted to the linkage shaft 105. The linkage shaft 105 then outputs power to the drive wheels 102 at both ends, causing the conveyor belt 103 on the drive wheels 102 to move. The bottom end of the transverse arm 30 is fixed to the conveyor belt 103. The displacement of the conveyor belt 103 can synchronously drive the transverse arm 30 to move on the track arm 101. The direction of this movement is the Y-axis direction. The forward and reverse rotation of the drive motor 104 changes the forward and reverse movement of the transverse arm 30 in the Y-axis direction.

[0043] refer to Figure 3 and Figure 4 The X-axis motion mechanism is mounted on the Y-axis motion mechanism;

[0044] The X-axis motion mechanism includes a support plate 40 and a control motor 402. A transverse slide bar 302 is fixed on both sides of the top of the transverse arm 30. A first rack 303 is fixed on one side of the transverse slide bar 302. A second slider 401 that is slidably connected to the transverse slide bar 302 is fixed on the bottom of the support plate 40. The control motor 402 is fixed on the surface of the support plate 40. The output end of the control motor 402 is provided with a drive tooth 403 that meshes with the first rack 303.

[0045] In the above scheme, the control motor 402 outputs power to the drive gear 403. The rotation of the drive gear 403 enables the support plate 40 to move freely on the transverse slide bar 302 in the X-axis direction. The forward and reverse rotation of the control motor 402 changes the forward and reverse movement of the support plate 40 in the X-axis direction. At the same time, the start of the drive motor 104 and the movement of the transverse arm 30 synchronously drive the support plate 40 to move in the forward and reverse directions in the Y-axis direction.

[0046] refer to Figures 6-8 The Z-axis motion mechanism is mounted on the X-axis motion mechanism;

[0047] The Z-axis motion mechanism includes a longitudinal arm 407 and a longitudinal motor 405. A wall plate 404 is mounted on the surface of the support plate 40. Four wall plates 404 are arranged in a rectangle. A third slider 409 is fixed on the inner wall of the wall plate 404. A longitudinal slide bar 410 that slides with the third slider 409 is fixedly connected to the side wall of the longitudinal arm 407. A gear 406 is provided at the output end of the longitudinal motor 405. A second rack 408 that meshes with the gear 406 is fixed on the side wall of the longitudinal arm 407. A hollow groove is provided in the middle of the transverse arm 30.

[0048] In the above scheme, the horizontal arm 30 passes through the hollow slot in the middle of the horizontal arm 30. By activating the vertical motor 405, the power output of the vertical motor 405 is transmitted to the gear 406. The rotation of the gear 406 allows the vertical arm 407 to move freely on the third slider 409 in the Z-axis direction. The forward and reverse rotation of the vertical motor 405 changes the forward and reverse movement of the vertical arm 407 in the Z-axis direction. At the same time, the activation of the control motor 402 drives the support plate 40 to move, thereby driving the vertical arm 407 to move in the forward and reverse directions in the X-axis direction. Combined with the Y-axis direction movement mechanism, the activation of the drive motor 104 can simultaneously drive the Z-axis direction movement mechanism and the X-axis direction movement mechanism to move in the forward and reverse directions in the Y-axis direction.

[0049] refer to Figures 5-10 The clamping and reversing mechanism is installed below the Z-axis motion mechanism;

[0050] The clamping reversing mechanism includes a swing rotary cylinder 50, which is fixed to the bottom of the longitudinal arm 407. The bottom output end of the swing rotary cylinder 50 is connected to a rotary disk 501, and a connecting plate 502 is fixed to the bottom of the rotary disk 501.

[0051] In the above scheme, the activation of the swing rotary cylinder 50 can drive the rotary disk 501 to rotate, thereby changing the angle of the clamping reversing mechanism. The commonly used adjustable range of the swing rotary cylinder 50 is 0° to 190°.

[0052] The purpose of this rotation angle is, for example, when the clamped product workpiece 70 is horizontal, after clamping the product workpiece 70, the swing rotation cylinder 50 is activated to change the direction of the clamped product workpiece 70 to the vertical direction. This allows for different placement direction requirements and improves the overall versatility of the equipment.

[0053] refer to Figure 5 and Figure 8 The connecting plate 502 has lugs 504 on both sides of the bottom. An assembly plate 503 is rotatably connected to the lugs 504. A second shaft block 507 is fixed to the front end of the assembly plate 503. A first shaft block 506 is fixed to the front end of the connecting plate 502. A push cylinder 505 is rotatably connected to the first shaft block 506. The output shaft of the push cylinder 505 is rotatably connected to the second shaft block 507.

[0054] In the above scheme, since the tail end of the assembly plate 503 is rotatably connected to the lug 504, when the output shaft of the push cylinder 505 is pushed out, the assembly plate 503 rotates around the lug 504 as the center axis, thereby changing the tilt angle of the assembly plate 503.

[0055] The purpose of adjusting the tilt angle of the assembly plate 503 is as follows: For example, when the plane on which the workpiece 70 is placed is an inclined plane, the tilt angle of the assembly plate 503 can be easily and quickly adjusted to be parallel to the inclined plane by activating the push cylinder 505. In this way, the workpiece 70 held by the clamping and reversing mechanism can be placed stably on the surface of the inclined plane.

[0056] refer to Figure 5 and Figure 8 A bidirectional cylinder 60 is fixed to the bottom of the assembly plate 503, and a push plate 601 is fixed to the output ends on both sides of the bidirectional cylinder 60. A clamping arm 602 is fixed to the bottom of the push plate 601.

[0057] The clamping arm 602 is detachably equipped with clamping blocks 603 on both sides, and the clamping blocks 603 hold the workpiece 70.

[0058] Below the beam frame 10, there are two sets of sorting mechanisms 20 in mirror symmetry. Several workpieces 70 are placed on the sorting mechanisms 20, and the clamping and reversing mechanism clamps the workpieces 70 within the sorting mechanisms 20.

[0059] In the above scheme, workpiece 70 is a single corner part of the inner and outer frames of the aluminum access port, and the inner and outer frames of the aluminum access port are composed of four workpieces 70; according to Figure 5 In the process, the clamping arm 602 holds several workpieces 70 arranged in a row. Each time, the clamping arm 602 clamps several workpieces 70 in the sorting mechanism 20 as a group (i.e., ... Figure 5 The sorting mechanism 20 here is embodied as any platform used to place the workpiece 70, without specific details of protection. The setting of two sets of sorting mechanisms 20 improves the supply of workpiece 70. The clamping block 603 is provided with a barb shape that matches the workpiece 70, which can easily support and clamp the workpiece 70. The two clamping arms 602 achieve synchronous adjustment of the distance through a two-way cylinder 60.

[0060] In summary, the Y-axis motion mechanism drives the X-axis motion mechanism, the Z-axis motion mechanism, and the clamping and reversing mechanism; the X-axis motion mechanism drives the Z-axis motion mechanism and the clamping and reversing mechanism; the Z-axis motion mechanism drives the clamping and reversing mechanism, which is used for clamping the workpiece 70, adjusting its direction, and adjusting its tilt angle.

[0061] Specifically, the X-axis motion mechanism, Y-axis motion mechanism, Z-axis motion mechanism, and clamping and reversing mechanism work together to complete material picking and unloading, thereby realizing material transfer.

[0062] The specific implementation process of this utility model is as follows:

[0063] Step 1:

[0064] When removing workpiece 70 from the sorting mechanism 20:

[0065] S1. First, the drive motor 104 on the Y-axis motion mechanism starts, and the conveyor belt 103 drives the transverse arm 30 to move on the track arm 101 to above the sorting mechanism 20.

[0066] S2. Then, the control motor 402 on the X-axis direction motion mechanism is started, controlling the support plate 40 to slide on the transverse slide bar 302 to above the corresponding set of sorting mechanisms 20 (so that the clamping reversing mechanism is located above the sorting mechanism 20).

[0067] S3. Next, the longitudinal motor 405 on the Z-axis motion mechanism is started, causing the longitudinal arm 407 to move on the third slider 409, thereby slowly moving the clamping reversing mechanism from above to below the sorting mechanism 20.

[0068] S4. Finally, the bidirectional cylinder 60 on the clamping reversing mechanism expands, widening the distance between the two clamping arms 602 to accommodate a certain number of workpieces 70. The bidirectional cylinder 60 is then activated again to retract, narrowing the distance between the two clamping arms 602, and a certain number of workpieces 70 are clamped by the clamping block 603. It should be noted that there are two sets of sorting mechanisms 20 here, which alternately clamp the workpieces through the clamping reversing mechanism.

[0069] Step Two: Material Feeding Process

[0070] S4. The longitudinal motor 405 on the Z-axis motion mechanism starts, and the longitudinal arm 407 slowly rises from bottom to top.

[0071] S5, the drive motor 104 on the Y-axis motion mechanism starts, moving the X-axis motion mechanism, Z-axis motion mechanism and clamping reversing mechanism away from the sorting mechanism 20 and moving them to the designated placement position (the "placement position" is any "conveyor belt production line").

[0072] The longitudinal motor 405 on the S6 and Z-axis motion mechanism starts, and the longitudinal arm 407 moves down, so that the workpiece 70 on the clamping arm 602 approaches the "conveyor belt production line".

[0073] S7. Control the expansion of the bidirectional cylinder 60, and the workpiece 70 is detached from the clamping arm 602 and laid flat on the "conveyor belt production line" for transportation to the next production line.

[0074] S8. Repeat the S1-S7 workflow (Note: The two sorting mechanisms 20 alternately grip the materials through the clamping and reversing mechanism. Only the control motor 402 on the X-axis direction motion mechanism needs to be changed to start, so as to realize the alternating gripping of materials).

[0075] "Exceptions" to Material Handling and Discharging

[0076] Exception 1:

[0077] When the clamped product workpiece 70 is horizontal, while the workpiece 70 placed on the "conveyor belt production line" needs to be vertical, the control of the swing rotary cylinder 50 is added during the clamping and unloading process. By activating the swing rotary cylinder 50, different placement direction requirements can be achieved.

[0078] Exception 2:

[0079] When the plane of the "conveyor belt production line" is inclined, this is reflected in the feeding process. During the feeding process in S7, the control of the push cylinder 505 is added. The push cylinder 505 can adjust the tilt angle of the assembly plate 503 to be parallel to the plane of the "conveyor belt production line". In this way, the workpiece 70 held by the clamping and reversing mechanism can be placed stably on the inclined plane of the "conveyor belt production line".

[0080] Finally, two exceptional steps were identified, and these two exceptional steps need to be added to the overall material handling and unloading process.

[0081] The specific control of this invention requires unified computer scheduling, such as: unified scheduling of integrated management of the central control system: through PLC (Programmable Logic Controller), SCADA (Supervisory and Data Acquisition System) or industrial computer, to centrally monitor and coordinate the status of all equipment and production parameters; it can also be combined with sensors and feedback mechanisms, etc.

[0082] The above embodiments are merely exemplary models of this utility model and are not intended to limit this utility model. The scope of protection of this utility model is defined by the claims. Various modifications or equivalent substitutions can be made to this utility model within its substance and scope of protection. Such modifications or equivalent substitutions should also be considered to fall within the scope of protection of this utility model.

[0083] In the description of this utility model, it should be noted that the terms "inner," "front," "rear," "left," and "right," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the attached circle, or the orientation or positional relationship commonly used when the utility model product is in use. They are used 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. Therefore, these terms indicating orientation or positional relationship should not be construed as limitations on this utility model.

[0084] In the description of this utility model, it should be further noted that, unless otherwise explicitly specified and limited, the terms "set" and "connection" should be interpreted broadly. For example, these terms can refer to a fixed connection, a detachable connection, or an integral connection between components; they can also refer to a mechanical connection or an electrical connection; or they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of these terms in this utility model according to the specific circumstances.
