[0022] In the optical device loading equipment, when the special-shaped workpiece is picked up by the adsorption method, the adsorption contact surface does not match the geometric characteristics of the workpiece due to the irregular profile of the workpiece, and the posture of the workpiece cannot be stably maintained during the picking process. Real-time posture correction is required through a vision system, thereby prolonging the single loading operation cycle and reducing the continuous operation efficiency of the equipment.

[0023] Specifically, in the automatic assembly scene of optical prisms, when the suction picking of the prism workpiece with an asymmetric profile is implemented by the taking mechanism, the workpiece rotates or tilts due to the offset of the center of gravity, and the vision system needs to repeatedly collect images and calculate and adjust the angle to match the target placement coordinates, so that the workpiece transfer process is interrupted multiple times, the production line beat is forced to be prolonged, and the overall output capacity of the equipment is restricted.

[0024] For this purpose, please refer to Figures 2 to 5The present application provides a product taking assembly, which comprises a support frame 10 and a taking mechanism 20, the taking mechanism 20 comprising a mounting plate 21 and a suction accessory 22, the mounting plate 21 being movably connected to the support frame 10, and the suction accessory 22 being movably connected to the side of the mounting plate 21 away from the support frame 10; the suction accessory 22 has a positioning counterbore 22a and a suction hole 22b in communication with the positioning counterbore 22a, and the suction hole 22b is located at the edge of the positioning counterbore 22a; the positioning counterbore 22a is used for inserting and limiting the special-shaped workpiece, and negative pressure suction is generated by the suction hole 22b.

[0025] The product taking assembly is a device for picking up and placing workpieces in an automated production line. The assembly aims to improve the precision and efficiency of workpiece handling, especially for irregularly shaped special-shaped workpieces.

[0026] The support frame 10 is the structural basis of the product taking assembly, used to carry and fix the taking mechanism 20 and install it in a specific working environment. The support frame 10 can adopt various structural forms, such as frame structure, column structure or cantilever structure, to adapt to different installation requirements and space limitations.

[0027] The taking mechanism 20 is the core functional component of the product taking assembly, responsible for the actual workpiece picking, moving and placing operations. The mechanism works cooperatively with its internal mounting plate 21 and suction accessory 22 to achieve precise grasping and positioning of the workpiece.

[0028] The mounting plate 21 is part of the taking mechanism 20, which serves as the mounting base of the suction accessory 22 and realizes the movable connection of the taking mechanism 20 on the support frame 10. The mounting plate 21 can be designed to move in one or more directions, such as being connected to the support frame 10 through guide rails, sliders or hinges, etc.

[0029] The suction accessory 22 is the part of the taking mechanism 20 that directly contacts the workpiece and generates negative pressure to adsorb the workpiece. The suction accessory 22 is usually composed of a cavity with a specific shape and a channel for generating negative pressure to ensure stable grasping of the special-shaped workpiece. The positioning counterbore 22a is a recessed structure on the suction accessory 22 for receiving the special-shaped workpiece. The shape and size of the counterbore are designed to match the specific part of the special-shaped workpiece, providing physical limiting when the workpiece is inserted, ensuring the initial position and attitude of the workpiece before being adsorbed.

[0030] The suction hole 22b is a channel on the suction accessory 22 that communicates with the positioning counterbore 22a, and the suction hole 22b is located at the edge of the positioning counterbore 22a, used to generate negative pressure in the positioning counterbore 22a. When negative pressure acts on the workpiece in the positioning counterbore 22a through the suction hole 22b, the workpiece is firmly adsorbed on the suction accessory 22.

[0031] An irregularly shaped workpiece refers to a workpiece with irregular geometric shape, which may contain curves, angles or asymmetric features on its surface, making it difficult for traditional planar suction or mechanical clamping to achieve accurate positioning and stable grabbing. The irregularly shaped workpiece in this embodiment is ASL Barra.

[0032] Negative pressure suction is a technology that uses the principle of air pressure difference for suction. By pumping air at the suction hole 22b, the air pressure inside the positioning counterbore 22a is lower than the external atmospheric pressure, thereby generating an inward suction force to firmly fix the workpiece on the suction member 22.

[0033] The present embodiment provides a product picking assembly, which includes a support frame 10 and a picking mechanism 20. The support frame 10 serves as the skeleton of the entire assembly, which can be a complex frame structure, and its main function is to provide a stable mounting base for the picking mechanism 20. The picking mechanism 20 is responsible for performing the actual workpiece picking operation. For example, the support frame 10 can be a metal rod fixed on a workbench, and the picking mechanism 20 is mounted on the metal rod in some way.

[0034] The picking mechanism 20 further includes a mounting plate 21 and a suction member 22. The mounting plate 21 is an intermediate component in the picking mechanism 20, which is used to connect the suction member 22 and the support frame 10. The suction member 22 is the part that directly contacts the workpiece. For example, the mounting plate 21 can be a rectangular plate, and the suction member 22 is fixed to one side of the rectangular plate.

[0035] The mounting plate 21 is movably connected to the support frame 10. This movable connection allows the mounting plate 21 to move on the support frame 10, so that the suction member 22 can reach different picking or placing positions. For example, the mounting plate 21 can be connected to the support frame 10 through a sliding rail, so that it can slide in the vertical direction; or the mounting plate 21 can be connected to the support frame 10 through a ball screw, so that it can slide in the vertical direction.

[0036] The suction member 22 is movably connected to the side of the mounting plate 21 away from the support frame 10. This connection allows the suction member 22 to have a certain mobility relative to the mounting plate 21, for example, the suction member 22 can be slightly adjusted in angle or telescoped relative to the mounting plate 21 to adapt to the slight positional deviation of the workpiece. For example, the suction member 22 can be connected to the mounting plate 21 through a telescopic rod, so that it can telescope in the axial direction.

[0037] The suction attachment 22 has a positioning recess 22a and a suction hole 22b connected to the positioning recess 22a. The positioning recess 22a is a recess or cavity on the suction attachment 22 for receiving a workpiece, which can be a simple circle, square or any other geometric shape as long as it can accommodate a portion of the irregular workpiece. The suction hole 22b is a passage connecting the inside of the positioning recess 22a to an external negative pressure source, which can be located on the side wall, top or bottom of the positioning recess 22a. For example, the positioning recess 22a can be a cylindrical recess, and the suction hole 22b is located on the side wall of the recess.

[0038] The positioning recess 22a is used to limit the insertion of the irregular workpiece. When the irregular workpiece is sent to the picking position, a specific part of it can be guided into the positioning recess 22a. The geometry of the positioning recess 22a provides physical constraints on the insertion direction and depth of the workpiece, thereby preliminarily calibrating the position and attitude of the workpiece before it is suctioned. For example, if the irregular workpiece has a protruding edge, the positioning recess 22a can be designed as a groove matching the shape of the edge, which is limited in the groove when the workpiece is inserted.

[0039] The suction hole 22b generates negative pressure suction. Once the irregular workpiece is preliminarily limited by the positioning recess 22a, the negative pressure source draws air through the suction hole 22b to form a negative pressure inside the positioning recess 22a. This negative pressure generates a suction force that firmly suction the workpiece to the inner wall of the positioning recess 22a, thereby completing the stable grasping of the workpiece. For example, the suction hole 22b can be connected to a vacuum pump, when the vacuum pump is started, the gas inside the positioning recess 22a is drawn out, and the workpiece is suctioned.

[0040] Suppose in an automated production line, a batch of irregularly shaped irregular workpieces need to be transferred from a bin to a tooling. Due to their unique geometric shape, these irregular workpieces are prone to angular and positional deviations under traditional suction methods, making subsequent assembly difficult.

[0041] The product picking assembly of the present embodiment is installed above the production line, with the support frame 10 fixed to the machine base 100. The mounting plate 21 of the picking mechanism 20 is movably connected to the support frame 10 through a slide rail, allowing the picking mechanism 20 to move horizontally to cover the area of the bin and the tooling. The suction attachment 22 is movably connected below the mounting plate 21 through a telescopic mechanism, allowing it to move vertically.

[0042] When a special-shaped workpiece needs to be picked up, the taking mechanism 20 first moves above the magazine. The suction accessory 22 is lowered, with its positioning sink hole 22a aligned with the special-shaped workpiece in the magazine. A specific protruding part of the special-shaped workpiece is guided to be inserted into the positioning sink hole 22a. Since the inner wall shape of the positioning sink hole 22a matches the protruding part, the special-shaped workpiece is physically limited during insertion, and its horizontal position and rotation angle are preliminarily calibrated to a preset accurate state.

[0043] Once the special-shaped workpiece is limited by the positioning sink hole 22a, the suction holes 22b inside the suction accessory 22 are activated, for example, by the connected vacuum pump starting to pump. A negative pressure is quickly formed inside the positioning sink hole 22a, generating a strong suction force that firmly sucks the special-shaped workpiece onto the inner wall of the positioning sink hole 22a. At this time, the special-shaped workpiece is not only sucked, but its posture and position are also accurately maintained through the physical limitation of the positioning sink hole 22a.

[0044] Subsequently, the taking mechanism 20 rises, taking the suction accessory 22 with the special-shaped workpiece out of the magazine. The mounting plate 21 moves along the slide rail on the support frame 10, accurately transporting the special-shaped workpiece above the target tooling. The suction accessory 22 is lowered again, placing the special-shaped workpiece into the predetermined position of the tooling. During placement, since the special-shaped workpiece maintains an accurate posture and position throughout the transfer process, no additional vision system is needed for posture adjustment. When the workpiece is placed in position, the suction holes 22b stop pumping, the negative pressure is released, and the special-shaped workpiece is released into the tooling.

[0045] Please refer to Figures 2 to 5 , the present application further proposes that in the above-mentioned product taking assembly, the suction holes 22b are located on the bottom wall of the positioning sink hole 22a.

[0046] Wherein, the suction holes 22b are located on the bottom wall of the positioning sink hole 22a, which means that the openings of the suction holes 22b are arranged on the bottom surface inside the positioning sink hole 22a, which is roughly perpendicular to the insertion direction of the special-shaped workpiece. This arrangement is designed to ensure that the negative pressure suction force can directly and effectively act on the bottom of the special-shaped workpiece, thereby providing the maximum suction contact area and the most stable suction effect when the workpiece is limited. The suction holes 22b can be one or more openings that directly penetrate the bottom wall of the positioning sink hole 22a. The bottom wall can be designed as a flat surface, or a concave-convex structure that matches the shape of the bottom of the special-shaped workpiece, with the suction holes 22b integrated into these structures. The suction holes 22b can be connected to a vacuum channel inside the suction accessory 22, which is connected to an external vacuum generating device. The shape of the suction holes 22b can be circular, oval, or slit-shaped to adapt to different suction needs and workpiece bottom shapes.

[0047] When the special-shaped workpiece is guided and inserted into the positioning hole 22a of the suction accessory 22, the bottom of the special-shaped workpiece will be in close contact with the bottom wall of the positioning hole 22a. Since the suction hole 22b is arranged on the bottom wall of the positioning hole 22a, once the negative pressure is applied through the suction hole 22b, the negative pressure will directly and uniformly act on the bottom surface of the special-shaped workpiece. This direct action ensures that the suction force can be efficiently transmitted and a reliable seal is formed between the workpiece and the bottom wall. In this way, the special-shaped workpiece is not only physically limited in the positioning hole 22a, but also firmly sucked by the negative pressure generated by the suction hole 22b on the bottom wall, thereby forming a double fixation, greatly enhancing the stability and reliability during the taking process, effectively avoiding displacement or falling of the workpiece during the transfer process due to unstable suction.

[0048] As a specific embodiment, the suction accessory 22 can be manufactured in an integrated manner, for example, by injection molding or 3D printing technology. The bottom wall of the positioning hole 22a can be designed as a plane or a curved surface matching the bottom contour of the special-shaped workpiece to be sucked. In the center position of the bottom wall, a circular suction hole 22b with a diameter of 2.5 millimeters can be arranged. The suction hole 22b is connected with the external vacuum pump through the channel reserved inside the suction accessory 22. When the special-shaped workpiece is placed into the positioning hole 22a, its bottom will cover the suction hole 22b, at which time the vacuum pump is started, and negative pressure is generated through the suction hole 22b to firmly suck the special-shaped workpiece on the bottom wall of the positioning hole 22a.

[0049] Referring to Figures 2 to 5 , the application further proposes that the number of suction holes 22b is two, and the two suction holes 22b are arranged in a spaced manner around the edge of the bottom wall of the positioning hole 22a.

[0050] Among them, the number of suction holes 22b is two, which means that the suction accessory 22 sets two independent negative pressure suction points on the bottom wall of the positioning hole 22a. This design can provide more dispersed and balanced suction force, avoiding the instability of suction caused by a single suction point. The two suction holes 22b can be independent holes connected with the negative pressure source through the internal channel, or can be openings with specific shapes and sizes. The arrangement around the edge of the bottom wall of the positioning hole 22a means that the two suction holes 22b are not concentrated in the central area of the bottom wall, but are distributed along the circumferential edge of the bottom wall and maintain a certain distance between each other. This arrangement can ensure that the suction force acts on multiple edge or peripheral contact points of the special-shaped workpiece, thereby enhancing the overall stability and anti-overturning ability of the special-shaped workpiece. For example, the two suction holes 22b can be symmetrically distributed on the edge of the bottom wall, or asymmetrically but spaced according to the specific shape and gravity distribution of the special-shaped workpiece.

[0051] The technical scheme of the present application provides two suction holes 22b arranged at intervals around the edge of the bottom wall of the positioning hole 22a of the suction accessory 22, so that when the special-shaped workpiece is inserted into the positioning hole 22a and subjected to negative pressure suction, the negative pressure suction force can act on multiple peripheral contact points of the workpiece. When the negative pressure source is started, the two suction holes 22b simultaneously generate negative pressure to firmly suction the special-shaped workpiece on the bottom wall of the positioning hole 22a. Since the suction holes 22b are located at the edge of the bottom wall and arranged at intervals, they can form a wider and more balanced suction area, effectively avoiding the concentration of suction force and the shaking of the workpiece caused by a single suction point. This multi-point, edge-distributed suction method is particularly effective for special-shaped workpieces with irregular shapes, off-center of gravity, or uneven contact surfaces, and can significantly improve the stability and reliability of suction, ensuring that the workpiece maintains the correct posture during material taking and transfer and is not prone to falling off or tilting.

[0052] As a specific embodiment, the bottom wall of the positioning hole 22a of the suction accessory 22 can be designed to match the shape of the bottom contour of the special-shaped workpiece. The two suction holes 22b can be machined into a circular or elliptical shape and arranged at intervals at an angle along the edge of the bottom wall, for example, at two opposite sides or two adjacent corners of the bottom wall. For example, if the bottom of the special-shaped workpiece is rectangular, the two suction holes 22b can be located near the edges of the two diagonal directions of the rectangular bottom wall, respectively. The negative pressure generated by the suction cylinder 222 of the suction hole 22b is communicated with the external vacuum system, and when the special-shaped workpiece is placed in the positioning hole 22a, the negative pressure acts on the bottom of the workpiece through the two suction holes 22b to achieve stable suction.

[0053] Through the above technical scheme, the product material taking assembly can provide more stable and reliable negative pressure suction for the special-shaped workpiece. The two suction holes 22b arranged at intervals around the edge of the bottom wall of the positioning hole 22a effectively disperse the suction force, avoid the shaking or tilting of the workpiece during suction due to uneven force, significantly improve the success rate of taking the special-shaped workpiece and the stability during transfer, and thus improve the working efficiency and reliability of the entire product material taking assembly.

[0054] Please refer to Figures 2 to 5 The present application further provides that the contour of the positioning hole 22a is adapted to the contour of the special-shaped workpiece. Among them, "adapted to" means that the internal shape of the positioning hole 22a and the external contour of the special-shaped workpiece are geometrically matched with each other, which can achieve close fitting.

[0055] This adaptation can be achieved in various ways. For example, a numerically controlled machining technique can be used to form a positioning counterbore 22a on the suction attachment 22 that perfectly matches the profile of the workpiece, based on an accurate three-dimensional model of the workpiece. Alternatively, a 3D printing technique can be used to produce a positioning counterbore 22a component with a matching profile based on the complex shape of the workpiece, and then integrate it into the suction attachment 22.

[0056] In addition, for production lines with multiple types of irregular workpieces, it is also possible to design replaceable positioning counterbore 22a modules, each corresponding to the profile of a specific type of irregular workpiece, to facilitate quick switching and adaptation to the requirements of different workpieces.

[0057] The scheme of the present application sets the profile of the positioning counterbore 22a to match the profile of the irregular workpiece, so that when the irregular workpiece is placed or inserted into the positioning counterbore 22a, it can be accurately guided and tightly accommodated therein. This tight mechanical fit provides an initial, stable limiting effect for the irregular workpiece, effectively preventing the workpiece from shaking, tilting, or mispositioning before suction. When the suction hole 22b subsequently generates negative pressure suction, since the irregular workpiece is already in the best positioning state, the negative pressure can more evenly and effectively act on the workpiece surface, thereby ensuring the firmness and reliability of the suction. The synergy of mechanical limiting and negative pressure suction significantly improves the accuracy and stability of the irregular workpiece taking.

[0058] The following is illustrated by a specific example. Suppose the irregular workpiece is an integrated circuit chip with multiple irregular protrusions and grooves. In this case, the profile of the positioning counterbore 22a can be designed as a groove that perfectly matches the external shape of the chip, including recesses corresponding to the chip protrusions and protrusions corresponding to the chip grooves. When the taking mechanism 20 lowers the chip above the suction attachment 22, the chip can accurately slide into the positioning counterbore 22a, with its irregular protrusions and grooves tightly engaging the matching structures of the positioning counterbore 22a, thereby achieving accurate limiting of the chip in the horizontal and rotational directions. Subsequently, the suction hole 22b generates negative pressure, firmly suctioning the chip to the bottom of the positioning counterbore 22a, ensuring that the chip does not shift or fall off during movement.

[0059] Through the above technical scheme, the irregular workpiece can obtain accurate and stable mechanical positioning before being taken, effectively avoiding the problem of inaccurate positioning or firm suction caused by the irregular shape of the workpiece. This significantly improves the accuracy and reliability of the product taking assembly in taking irregular workpieces, reduces the risk of workpiece damage during the taking process, and thus improves the automation production efficiency and stability of the entire workpiece feeding machine.

[0060] Please refer to Figures 2 to 5The application further proposes that the above-mentioned suction accessory 22 comprises a suction cylinder 221, the bottom wall of the suction cylinder 221 is provided with an opening, a limiting plate 221a is arranged at the opening, the limiting plate 221a and the side wall of the suction cylinder 221 jointly form the above-mentioned positioning counterbore 22a, the limiting plate 221a is provided with the above-mentioned suction hole 22b, and a suction air cylinder 222 is connected to one end of the suction cylinder 221 and communicates with the suction hole 22b.

[0061] The suction cylinder 221 is the main structure of the suction accessory 22, which is usually in the shape of a cylinder or a hollow structure with a specific cross section. The internal space is used to accommodate or cooperate with other components and provide structural support for the suction of workpieces. The suction cylinder 221 can be made of metal materials (such as aluminum alloy, stainless steel) or high-strength engineering plastics (such as polyformaldehyde, polycarbonate) to meet the requirements of strength, wear resistance and light weight. Its shape and size can be customized according to the size and shape of the workpiece to be suctioned in actual application.

[0062] The bottom wall of the suction cylinder 221 is provided with an opening, which is designed to provide space for the subsequent installation of the limiting plate 221a and enable the positioning counterbore 22a to be formed in the lower area of the suction cylinder 221. The opening can be circular, square or any shape matching the profile of the special-shaped workpiece, and its size should be sufficient to accommodate the limiting plate 221a and ensure the effective formation of the positioning counterbore 22a. The limiting plate 221a is a key component for forming the positioning counterbore 22a together with the side wall of the suction cylinder 221. It is usually a plate-shaped structure with a specific shape and thickness, and its interior or surface can be processed to have holes for suction. The limiting plate 221a can be made of the same material as the suction cylinder 221, or it can be made of a material with better wear resistance or friction coefficient, such as polyurethane, rubber or special engineering plastics, to protect the surface of the workpiece and increase the limiting effect.

[0063] By installing the limiting plate 221a at the opening of the bottom wall of the suction cylinder 221 and jointly defining a space with a specific shape and depth with the inner side wall or lower edge of the suction cylinder 221, the positioning counterbore 22a is formed. This enclosing structure ensures the accuracy of the shape and size of the positioning counterbore 22a, which can tightly fit the profile of the special-shaped workpiece, thereby achieving precise insertion limiting of the workpiece. The suction hole 22b is arranged on the limiting plate 221a, so that the suction hole 22b can be directly located at the bottom or side wall of the positioning counterbore 22a, so that after the workpiece is inserted into the positioning counterbore 22a, the suction hole 22b can directly act on the surface of the workpiece to generate negative pressure suction. The number and position of the suction hole 22b can be designed according to the shape, size and suction force requirements of the workpiece, for example, it can be a central hole, or multiple holes distributed around.

[0064] The suction cylinder 222 is an actuating element that generates negative pressure or positive pressure using compressed air. In this application, it is mainly used to generate negative pressure to achieve the suction of workpieces. The suction cylinder 222 typically includes a cylinder body, a piston, a piston rod, and inlet and outlet ports. Its working principle is to control the direction and pressure of air flow to make the piston reciprocate in the cylinder body, thereby forming negative pressure in the cavity connected to the suction hole 22b. The suction cylinder 222 can be a single-acting or double-acting cylinder, and its stroke and thrust / suction force can be selected according to actual needs. The suction cylinder 222 is mechanically connected to one end of the suction barrel 221 through its output end (usually a gas port or a connecting seat) to ensure the sealing and stability of the air flow path. This connection can be a threaded connection, a flange connection, or a buckle connection, etc., depending on the structural design of the suction barrel 221 and the suction cylinder 222. The suction cylinder 222 is connected to the suction hole 22b on the limiting plate 221a through internal air passages or external pipelines to establish an airtight connection. When the suction cylinder 222 works to generate negative pressure, the negative pressure is transmitted to the suction hole 22b through the communication path, and then acts on the surface of the workpiece in the positioning counterbore 22a to achieve the suction of the workpiece. This communication method ensures that the negative pressure can efficiently and directly act on the workpiece, improving the reliability of the suction.

[0065] Specifically, the suction barrel 221 serves as the main body of the suction member 22, and the opening of its bottom wall provides a structural basis for the installation of the limiting plate 221a. The limiting plate 221a is ingeniously arranged at the opening and cooperates with the side wall of the suction barrel 221 to form a positioning counterbore 22a that matches the profile of the special-shaped workpiece. This structure allows the special-shaped workpiece to be accurately inserted into the positioning counterbore 22a when it is moved by the material taking mechanism 20 to the position below the suction member 22 and is limited by the side wall of the counterbore, thereby achieving the preliminary centering and position fixing of the workpiece.

[0066] On this basis, the adsorption hole 22b is directly arranged on the limiting plate 221a, ensuring that the adsorption hole 22b can closely fit or be close to the surface of the workpiece in the positioning counterbore 22a. The adsorption cylinder 222 is connected with one end of the adsorption cylinder 221, and is in airtight communication with the adsorption hole 22b on the limiting plate 221a through an internal or external gas path. When the adsorption cylinder 222 is activated, it generates negative pressure at the adsorption hole 22b. Since the workpiece has been accurately positioned by the positioning counterbore 22a, the negative pressure can efficiently act on the surface of the workpiece, firmly adsorbing the workpiece in the positioning counterbore 22a. This integrated design organically combines the mechanical positioning of the workpiece with the negative pressure adsorption function, avoiding the problems of unstable adsorption or inaccurate positioning that may exist in traditional suction cups, especially for irregular-shaped workpieces, which can provide more stable and reliable material taking operations. In this way, the adsorption assembly 22 not only realizes accurate insertion positioning of irregular-shaped workpieces, but also ensures the effectiveness and reliability of negative pressure adsorption, significantly improving the adaptability and material taking success rate of the material taking assembly to irregular-shaped workpieces.

[0067] As a specific embodiment, the adsorption cylinder 221 can be made of a precisely machined aluminum alloy material, and the inner diameter thereof is determined according to the maximum outer dimension of the irregular-shaped workpiece to be adsorbed. The bottom wall of the adsorption cylinder 221 can be machined into a rectangular opening, the size of which is slightly larger than the projection area of the irregular-shaped workpiece. The limiting plate 221a can be made of a wear-resistant polyurethane material, the outer shape of which matches the rectangular opening of the bottom wall of the adsorption cylinder 221, and is fixed on the bottom wall of the adsorption cylinder 221 by screws. The inner side edge of the limiting plate 221a and the inner side wall of the adsorption cylinder 221 together form a positioning counterbore 22a that accurately matches the contour of the irregular-shaped workpiece, for example, if the irregular-shaped workpiece is L-shaped, the positioning counterbore 22a is also L-shaped. Two adsorption holes 22b can be provided on the limiting plate 221a, which are located at the bottom wall of the positioning counterbore 22a and symmetrically distributed below the two main arms of the L-shaped workpiece.

[0068] Through the above technical solution, the structure of the adsorption assembly 22 is optimized, realizing the close integration of the positioning counterbore 22a and the adsorption hole 22b. The synergistic effect of the adsorption cylinder 221, the limiting plate 221a and the adsorption cylinder 222 enables the irregular-shaped workpiece to be accurately mechanically positioned by the positioning counterbore 22a when being taken, effectively solving the problem of possible deflection or shaking of the workpiece before adsorption. Subsequently, the adsorption hole 22b provided on the limiting plate 221a can directly and efficiently apply negative pressure to the positioned workpiece, ensuring the firmness and reliability of adsorption. This design not only improves the material taking accuracy and stability of irregular-shaped workpieces and reduces the material taking failure rate, but also through structural integration, makes the structure of the entire adsorption assembly 22 more compact, facilitating installation and maintenance, thereby significantly improving the adaptability and working efficiency of the product material taking assembly to irregular-shaped workpieces.

[0069] Referring to Figures 2 to 5 The product taking assembly further includes a plurality of mounting plates 21 and a plurality of suction accessories 22. Each of the plurality of mounting plates 21 is movably connected to the support frame 10. Each of the plurality of suction accessories 22 is movably connected to one of the plurality of mounting plates 21 away from the support frame 10.

[0070] The plurality of mounting plates 21 means more than one mounting plate 21, which can independently or cooperatively carry the suction accessories 22 and realize movement relative to the support frame 10. These mounting plates 21 can be movably connected in various ways, for example, each mounting plate 21 can be installed on an independent linear guide on the support frame 10, and driven by a servo motor or a pneumatic cylinder to move along the guide; or a plurality of mounting plates 21 can be commonly installed on a gantry structure, which is movably connected to the support frame 10, thereby realizing overall movement and local fine adjustment of each mounting plate 21.

[0071] The plurality of suction accessories 22 means a number of suction accessories 22 corresponding to the plurality of mounting plates 21. Each suction accessory 22 has the same function as a single suction accessory 22, i.e., has a positioning counterbore 22a and a suction hole 22b for inserting and limiting and negative pressure suctioning of the special-shaped workpiece. Each suction accessory 22 is movably connected to the corresponding mounting plate 21 away from the support frame 10. This connection allows the suction accessory 22 to move relative to the mounting plate 21, for example, vertically, a small range of translation or rotation, to adapt to the precise taking and placing requirements of the workpiece. For example, the suction accessory 22 can be connected to the mounting plate 21 through a small pneumatic cylinder or an electric push rod to realize vertical extension and retraction; or through a universal joint or a flexible connecting piece to allow it to adjust the angle within a certain range.

[0072] The scheme of the present application introduces a plurality of mounting plates 21 and a plurality of suction accessories 22 in the taking mechanism 20, so that the product taking assembly can be converted from a single workpiece processing mode to a multi-workpiece parallel processing mode. Each mounting plate 21 is movably connected to the support frame 10, ensuring that each taking unit (the combination of the mounting plate 21 and the suction accessory 22) has independent positioning capability. At the same time, each suction accessory 22 is movably connected to the corresponding mounting plate 21, further ensuring the flexibility and accuracy of each suction accessory 22 when performing taking operations. This multi-unit parallel working structure enables the product taking assembly to simultaneously position, suction and transfer multiple special-shaped workpieces, thereby significantly improving the taking efficiency of the workpieces and the overall throughput of the production line. This design ingeniously integrates multiple independent taking functions into an expandable system, while maintaining the precise taking capability of a single suction accessory 22, greatly improving the operation efficiency and capacity of the entire assembly.

[0073] The following is described by a specific example. The product taking assembly can include three sets of mounting plates 21 and suction attachments 22. The three sets of mounting plates 21 can be respectively mounted on three parallel linear guides above the support frame 10, one mounting plate 21 on each guide, and driven by independent linear motors to enable independent movement in the horizontal direction. Each suction attachment 22 is connected to the corresponding mounting plate 21 below through a small servo electric cylinder to realize precise lifting and suction in the vertical direction. When three special-shaped workpieces need to be taken out from the warehouse, the control system can instruct the three mounting plates 21 to move to the preset taking position at the same time, and then the corresponding suction attachments 22 are lowered to position the workpieces through the positioning hole 22a and generate negative pressure through the suction hole 22b to suck the workpieces. After the suction is completed, the three suction attachments 22 can be lifted at the same time or in sequence, and moved to the placement position with the mounting plates 21 to place the workpieces into the tooling.

[0074] Through the above technical solution, the product taking assembly is expanded from a single taking unit to multiple taking units working in parallel. This multi-unit configuration enables the product taking assembly to handle multiple special-shaped workpieces at the same time or complete more workpiece taking and placing operations in the same time. This significantly improves the workpiece taking efficiency and the overall throughput of the production line, effectively shortens the production cycle, and solves the problem of low efficiency of the single taking unit when handling a large number of workpieces, thereby improving the production capacity of the automated production line.

[0075] Please refer to Figures 2 to 5 The present application further proposes that the taking mechanism 20 further includes a plurality of rotary motors 23, each rotary motor 23 being fixed to a mounting plate 21 and in transmission connection with a suction cylinder 222 to drive a suction cylinder 222 and a suction cylinder 221 to rotate.

[0076] The rotating motor 23 is a device capable of converting electrical energy into mechanical energy and generating rotary motion, which functions to provide rotary power to enable the connected components to make angular adjustments about their axes. The rotating motor 23 can adopt a stepper motor to achieve precise angular positioning by precisely controlling pulse signals, or a servo motor to achieve high-precision and high-response rotary motion through closed-loop control. The rotating motor 23 is fixed to a mounting plate 21, meaning that the relative position between the rotating motor 23 and the mounting plate 21 is fixed through mechanical connection to ensure that the rotating motor 23 can stably provide rotary power when working and accurately transmit its rotary motion to the adsorption cylinder 222 and the adsorption cylinder 221. This fixing method can directly fix the rotating motor 23 body on the mounting plate 21 through fasteners such as bolts and rivets, or install the rotating motor 23 on the mounting plate 21 through a transitional connecting piece (such as a bracket or a flange). The rotating motor 23 is in transmission connection with the adsorption cylinder 222, meaning that mechanical connection is established between the rotating motor 23 and the adsorption cylinder 222, so that the rotary motion of the rotating motor 23 can be transmitted to the adsorption cylinder 222. This transmission connection can adopt gear transmission to transmit rotary motion through gear engagement, or synchronous belt transmission to achieve smooth and precise transmission.

[0077] Finally, the rotating motor 23 drives the adsorption cylinder 222 and the adsorption cylinder 221 to rotate through transmission connection, thereby achieving angular adjustment or orientation of the special-shaped workpiece adsorbed on the adsorption member 22 to meet the requirements of subsequent processes on the posture of the workpiece.

[0078] The scheme of the present application introduces multiple rotating motors 23 in the material taking mechanism 20, so that each adsorption member 22 can actively adjust the angle of the special-shaped workpiece after taking it. Specifically, when the adsorption member 22 of the material taking mechanism 20 takes the special-shaped workpiece, the rotating motor 23 corresponding to the adsorption member 22 is activated. The rotating motor 23 is fixed to the mounting plate 21, and the rotary power generated thereby is transmitted to the adsorption cylinder 222 through transmission connection. Since the adsorption cylinder 221 is connected to the adsorption cylinder 222, the rotation of the adsorption cylinder 222 will synchronously drive the adsorption cylinder 221 and the special-shaped workpiece adsorbed thereon to rotate. This design enables the posture of the special-shaped workpiece to be accurately adjusted according to a preset program or real-time feedback after being taken, thereby solving the problem that angular adjustment of the workpiece cannot be achieved by relying solely on linear motion. In this way, the product taking assembly can not only achieve grasping and planar movement of the workpiece, but also achieve precise angular positioning of the workpiece, greatly improving the flexibility and functionality of the taking assembly in handling complex special-shaped workpieces in an automated production line, so that it can adapt to more diversified assembly and processing requirements.

[0079] As a specific implementation, the rotary motor 23 can be a compact stepper motor, which is firmly fixed on the mounting plate 21 through a customized mounting bracket. A drive gear can be installed on the output shaft of the stepper motor, and the body or connecting part of the suction cylinder 222 is integrated with a driven gear meshing with the drive gear. When the stepper motor receives a control signal, its drive gear rotates, thereby driving the driven gear and the suction cylinder 222 to rotate. Since the suction cylinder 221 is tightly connected with the suction cylinder 222, the suction cylinder 221 also rotates, thereby achieving precise angular adjustment of the special-shaped workpiece suctioned in the positioning hole 22a. For example, if the special-shaped workpiece needs to be rotated by 90 degrees to be inserted into the next station, the stepper motor can precisely control the suction cylinder 221 to rotate by 90 degrees. In addition, a small servo motor can also be used, whose output shaft is directly connected with the suction cylinder 222 through a high-precision coupling, to achieve faster, smoother and high-precision rotation control.

[0080] Through the above technical solution, after the product taking assembly sucks the special-shaped workpiece, it can actively and accurately adjust the angle of the special-shaped workpiece, effectively solving the problem that the traditional taking assembly cannot adjust the angle or needs additional process for calibration when processing special-shaped workpieces that need a specific posture. This significantly improves the automation degree and efficiency of workpiece processing, reduces manual intervention and potential positioning errors, so that the product taking assembly can better adapt to complex and variable automated production and assembly requirements, thereby improving the flexibility and production efficiency of the entire production line.

[0081] Please refer to Figure 1 The present application further proposes that the taking mechanism 20 further comprises a plurality of connecting plates 24, an assembly plate 25 and a plurality of lifting cylinders 26. The plurality of connecting plates 24 are used to establish mechanical connection between the telescopic rods of the lifting cylinders 26 and the mounting plate 21. Each connecting plate 24 transmits the vertical movement of one lifting cylinder 26 to the corresponding mounting plate 21, thereby driving the suction member 22 to ascend or descend.

[0082] The connecting plate 24 can be implemented in various forms, for example, it can be a rigid metal plate or connecting block, which is fixedly connected with the end of the telescopic rod of the lifting cylinder 26 and the mounting plate 21 through bolts, rivets or other fasteners; or it can be designed as a structural member with a specific geometric shape to adapt to different connection requirements and space limitations.

[0083] The assembly plate 25 serves as the mounting base of the plurality of lifting cylinders 26 and is movably connected to the support frame 10. Its main function is to bear and fix the plurality of lifting cylinders 26, while allowing it to move as a whole on the support frame 10 to match the overall movement of the material taking mechanism 20. The movable connection mode of the assembly plate 25 can include but is not limited to: linear sliding connection by matching the slider with the guide rail on the support frame 10; or smooth movement by the roller mechanism on the support frame 10.

[0084] The plurality of lifting cylinders 26 are actuating mechanisms that provide vertical driving force to drive the suction accessories 22 to lift. The telescopic rod of each lifting cylinder 26 is connected with a connecting plate 24, and the extension and retraction of the lifting cylinder 26 is controlled by air pressure, so as to realize accurate vertical positioning of the suction accessories 22. The lifting cylinder 26 can adopt various types, for example, it can be a single-acting cylinder that is pushed out by air pressure and retracted by spring or gravity; it can also be a double-acting cylinder that is controlled to extend and retract by air pressure, providing stronger control ability and positioning accuracy; in addition, other linear driving devices such as electric push rods can also be used to realize the lifting function.

[0085] The scheme of the present application provides accurate and independent vertical movement capability for the material taking mechanism 20 of the product material taking assembly by introducing a plurality of connecting plates 24, an assembly plate 25 and a plurality of lifting cylinders 26. Specifically, the assembly plate 25 is movably connected to the support frame 10, so that it can move horizontally as a whole with the material taking mechanism 20. The plurality of lifting cylinders 26 are mounted on the assembly plate 25, thereby ensuring the synchronous movement of the lifting cylinders 26 and the material taking mechanism 20. The telescopic rod of each lifting cylinder 26 is connected with a connecting plate 24, and each connecting plate 24 is connected with a mounting plate 21. Since each mounting plate 21 movably connects a suction accessory 22, when the lifting cylinder 26 receives a control signal and extends or retracts, the telescopic rod of the lifting cylinder 26 drives the connecting plate 24, and then drives the mounting plate 21 and the suction accessory 22 thereon to move vertically. This structure enables each suction accessory 22 to move horizontally on the support frame 10 through the mounting plate 21, and also enables accurate vertical positioning through the independent lifting cylinder 26. In this way, the material taking mechanism 20 can independently or synchronously adjust the vertical height of the plurality of suction accessories 22 according to actual needs, so as to more accurately adapt to the height difference of the workpieces or the depth requirement of the tooling when taking and placing the special-shaped workpieces, thereby significantly improving the accuracy and flexibility of the taking and placing operation.

[0086] As a specific embodiment, the above technical means can be implemented with reference to the following examples. The assembly plate 25 can be a rectangular frame composed of aluminum alloy profiles, with linear slides mounted on both sides of the bottom, which cooperate with the pre-set linear guide rails on the support frame 10, thereby realizing the smooth movable connection of the assembly plate 25 on the support frame 10. A plurality of lifting cylinders 26, for example, small double-acting cylinders with a stroke of 50 mm, are fixed on the top of the assembly plate 25 through cylinder mounting seats. The telescopic rod end of each lifting cylinder 26 is bolted to the side of the corresponding mounting plate 21 through an L-shaped connecting plate 24. The L-shaped connecting plate 24 is made of stainless steel material and has sufficient rigidity to transmit the thrust of the lifting cylinder 26. When it is necessary to adjust the vertical position of the suction accessory 22, the pneumatic control system supplies or exhausts air to the corresponding lifting cylinder 26, so that the telescopic rod of the cylinder extends or retracts, thereby driving the connecting plate 24, the mounting plate 21 and the suction accessory 22 to move upward or downward as a whole, realizing the accurate vertical picking and placing of the special-shaped workpiece.

[0087] Through the above technical solution, the product picking mechanism 20 obtains precise and controllable vertical movement capability. The introduction of multiple connecting plates 24, assembly plates 25 and lifting cylinders 26 enables each suction accessory 22 to independently or synchronously move vertically while moving horizontally. This effectively solves the problem of insufficient vertical positioning accuracy caused by height differences of workpieces or depth requirements of tooling when picking and placing special-shaped workpieces. This solution significantly improves the adaptability of the product picking mechanism 20 to workpieces of different sizes and placement environments, ensuring that the workpieces can be accurately inserted into the positioning hole 22a and subjected to negative pressure adsorption by the suction hole 22b, or accurately placed at the target position, thereby improving the overall operation precision, stability and production efficiency of the product picking mechanism 20.

[0088] Please refer to Figure 2 and Figure 1 , the present application also proposes a workpiece feeding machine, which comprises a base 100, an inlet flow line 200, an outlet flow line 300, a tool positioning assembly 400 and the above-mentioned product picking assembly.

[0089] Among them, the base 100 is the basic structure of the workpiece feeding machine, its main function is to provide a stable mounting platform and support for each functional module on the machine. It can be made of high-strength steel or cast aluminum in various materials and structures, such as welded together, or integrally formed, to ensure the rigidity and stability of the entire machine during operation, effectively suppress vibration and ensure equipment operation precision.

[0090] The infeed line 200 is a conveying mechanism for transporting empty tooling to the workpiece loading position. Its implementation can include but is not limited to: using a belt conveyor, conveying the tooling from the entry end to the designated position through continuous belt movement; or using a drum conveyor, pushing the tooling forward through the rotation of the driven drum; or a chain conveyor, carrying the tooling through the chain-driven tray or clamp. The line is usually equipped with sensors to detect the arrival of the tooling.

[0091] The outfeed line 300 is a conveying mechanism for removing the tooling loaded with workpieces from the loading station. It is usually arranged adjacent to the infeed line 200 to form a smooth material flow. Its implementation is similar to the infeed line 200, which can adopt the form of belt, drum or chain conveyor, etc., to ensure that the tooling loaded with workpieces can be stably and efficiently transferred from the loading area to the next process.

[0092] The tool positioning assembly 400 is used to accurately position and lift the tooling on the infeed line 200 to a preset height during the workpiece loading process, so that the product picking assembly can accurately place the workpiece into the tooling. The tool positioning assembly 400 of the embodiment includes a base plate, an electric cylinder mounted on the base plate, and a tool lifting mechanism mounted at the output end of the electric cylinder. The electric cylinder drives the tool lifting mechanism to move below the infeed line 200, and the tool lifting mechanism is used to lift the tooling at the infeed line 200.

[0093] The tool positioning assembly 400 of other embodiments can be implemented by a cylinder-driven lifting mechanism, for example, by the synchronous action of two or more cylinders, driving the lifting pin or lifting platform to lift the tooling from above the line; or a lifting platform driven by a servo motor, to achieve more accurate height control and positioning.

[0094] The support frame 10 of the product picking assembly is mounted on the base 100, which establishes the macro position of the product picking assembly in the entire workpiece loading station. This mounting method ensures the stability and working accuracy of the picking assembly, so that it can reliably perform the workpiece grabbing and placing tasks. The support frame 10 can be connected to the base 100 by screwing, welding or buckle connection, etc., to meet different installation and maintenance needs.

[0095] The infeed flow line 200, outfeed flow line 300, and tool positioning assembly 400 are arranged below the support frame 10 of the product handling assembly. This layout optimizes space utilization and enables the handling mechanism 20 to operate on the tool from above. This relative positional relationship enables the handling mechanism 20 to conveniently access the tool for workpiece picking and placing, while avoiding interference with other components. The handling mechanism 20 of the product handling assembly undertakes the core material handling function, i.e., picking up workpieces from a predetermined feeding location (e.g., a hopper or staging area) and placing them accurately into an empty tool that has been raised by the tool positioning assembly 400 on the infeed flow line 200. This process typically involves horizontal movement, vertical lifting, and possibly rotational action of the handling mechanism 20 to accommodate the geometry and placement requirements of different workpieces and tools.

[0096] The workpiece feeding machine of the present application achieves automated and efficient workpiece feeding by integrating multiple functional modules. First, an empty tool is transported to a predetermined feeding location by the infeed flow line 200. Once the tool is in place, the tool positioning assembly 400 raises it from the flow line and accurately fixes it, preparing for workpiece placement. Meanwhile, the handling mechanism 20 of the product handling assembly uses the positioning hole 22a and suction hole 22b of its suction accessory 22 to pick up a special-shaped workpiece from the feeding location. After picking up the workpiece, the handling mechanism 20 moves above the positioned tool and, through precise lifting and possibly rotational action, accurately places the workpiece into the limiting structure of the tool. After completing workpiece placement, the tool positioning assembly 400 lowers the tool loaded with the workpiece back onto the infeed flow line 200, and then the tool is removed from the machine by the outfeed flow line 300, completing a feeding cycle. Throughout the process, the base 100 provides stable support for all components, ensuring the accuracy of the coordinated work of each mechanism. This integrated solution enables the originally independent handling assembly to operate efficiently in an automated environment, solving the limitations of a single handling assembly that cannot achieve continuous and accurate feeding.

[0097] As a specific embodiment, the base 100 of the workpiece loading machine can be welded from a steel plate with a thickness of 10 mm and undergo surface plastic spraying treatment to provide good structural strength and corrosion resistance. The feeding flow line 200 and the discharging flow line 300 can adopt synchronous belt conveyors with a width of 200 mm, which are driven by servo motors to ensure smooth conveying and accurate parking of the tooling. The tooling positioning assembly 400 can be composed of two side-by-side mounted pneumatic lifting cylinders, and a V-shaped block is mounted on the top rod of each cylinder to cooperate with the positioning groove at the bottom of the tooling to achieve accurate lifting and positioning of the tooling. The support frame 10 of the product taking assembly can be a gantry structure, and a linear guide rail and a sliding block are mounted on the cross beam of the support frame 10 to carry the mounting plate 21 of the taking mechanism 20 and allow the mounting plate 21 to move in the horizontal direction. The suction member 22 of the taking mechanism 20 can be customized to have a positioning counterbore 22a according to the shape of the special-shaped workpiece, for example, for L-shaped workpieces, the positioning counterbore 22a can be designed to have an L-shaped profile, and the suction hole 22b is located at the bottom wall of the L-shaped counterbore. After the workpiece is sucked, the taking mechanism 20 is lowered by the Z-axis module driven by the servo motor to place the workpiece into the tooling.

[0098] Through the above technical solution, the workpiece loading machine provided by the present application effectively solves the problem of integration and efficient operation of the product taking assembly in the automatic production line. By providing the feeding flow line 200, the discharging flow line 300 and the tooling positioning assembly 400, automatic conveying, accurate parking and positioning of the empty tooling, and automatic removal of the tooling loaded with workpieces are achieved. The taking mechanism 20 of the product taking assembly can stably and accurately transfer the workpiece from the loading position to the tooling, significantly improving the automation degree and efficiency of workpiece loading. This integrated design avoids manual intervention, reduces operation errors, and ensures the continuity and stability of the production process, thereby improving the automation level and production efficiency of the entire production line.

[0099] Please refer to Figure 2 and Figure 1 , the workpiece loading machine further comprises a stock bin assembly 500 mounted on the base 100, the stock bin assembly 500 is located below the support frame 10 and is spaced apart from the feeding flow line 200; the stock bin assembly 500 is used for loading workpieces for the taking mechanism 20 of the product taking assembly to suck the workpieces.

[0100] Specifically, the magazine assembly 500 is a device for storing and orderly presenting workpieces. For example, the magazine assembly 500 is designed as a vertically stacked structure, specifically including a welding rack, a tray transfer mechanism, two tray lifting mechanisms, and two tray taking and placing mechanisms, the tray transfer mechanism is arranged at the top of the welding rack; the welding rack has an upper loading position and a lower loading position, the two tray lifting mechanisms are respectively installed in the upper loading position and the lower loading position, and the two tray taking and placing mechanisms are respectively installed at the top of the upper loading position and the lower loading position.

[0101] The worker places the tooling with the workpiece sleeve on the tray lifting mechanism at the upper loading position, at this time the tray lifting mechanism lifts the tooling loaded with workpieces to the top, the tray taking and placing mechanism sucks the tooling and translates the tooling to the taking position of the welding mechanism, at this time the taking mechanism 20 takes the workpieces from the taking position; after all the workpieces on the tooling are taken away, the tray transfer mechanism moves to the lower position of the tooling, so that the tray taking and placing mechanism places the empty tooling on the tray transfer mechanism, and the tray transfer mechanism moves the empty tooling to the top of the lower loading position; at this time, the tray lifting mechanism at the lower loading position rises to the top, the tray transfer mechanism lowers the empty tooling to the tray lifting mechanism, and the tray lifting mechanism lowers the empty tooling to the bottom of the welding rack, and the worker takes away the empty tray from the lower loading position outlet of the welding rack.

[0102] The magazine assembly 500 can be a vibrating tray that orients and transports scattered workpieces to a designated position through vibration; or it can be a stacked magazine, in which workpieces are stored in a stacked manner and are sent out one by one by a push rod or a conveying mechanism; or it can be a tray magazine, in which workpieces are placed in a tray in advance, and the tray is moved by an indexing mechanism to present the workpieces.

[0103] The magazine assembly 500 is installed on the base 100, which means that it is firmly connected to the main structure of the workpiece loading machine by bolts, welding or other fixing methods, to ensure its stability and positioning accuracy during operation. The magazine assembly 500 is located below the support frame 10, and this spatial layout enables the taking mechanism 20 of the product taking assembly to move downward to grab workpieces from the magazine assembly 500. The magazine assembly 500 is spaced apart from the feeding line 200, and this spacing design is intended to avoid physical interference between the operation of the magazine assembly 500 and the movement of the tooling on the feeding line 200, to ensure that the two work independently and coordinately. The function of the magazine assembly 500 is to continuously or on-demand provide workpieces so that they are in a position that can be accurately recognized and sucked by the taking mechanism 20 of the product taking assembly.

[0104] The technical scheme of the present application provides a material bin assembly 500 on the base 100 of the workpiece feeding machine, which is positioned below the support frame 10 and spaced apart from the feeding flow line 200, thereby providing a stable, orderly and automated workpiece supply source for the workpiece taking mechanism 20 of the product taking assembly. The material bin assembly 500 is responsible for arranging and positioning the bulk or disordered workpieces and accurately presenting them at a fixed taking position. The suction member 22 of the workpiece taking mechanism 20 has a positioning counterbore 22a and a suction hole 22b, which can accurately lower and suck the workpiece according to the position and posture of the workpiece provided by the material bin assembly 500. This configuration enables the workpiece taking mechanism 20 to continuously obtain workpieces without manual intervention and transfer them to the tooling on the feeding flow line 200. The spatial separation of the material bin assembly 500 and the feeding flow line 200 ensures that the workpiece supply and tooling transmission processes do not interfere with each other, thereby ensuring smooth operation and high efficiency of the entire workpiece feeding machine.

[0105] Through the above technical scheme, the workpiece feeding machine can realize automatic supply of workpieces, continuously providing workpieces to be processed to the product taking assembly without manual intervention. This significantly improves the automation level and production efficiency of the entire feeding process, reduces labor costs and operation intensity. At the same time, the orderly feeding of the material bin assembly 500 ensures that the workpiece taking mechanism 20 can stably and accurately suck the workpieces, reducing the workpiece taking failure rate caused by inconsistent positions or postures of the workpieces, thereby improving the operation reliability and production yield of the equipment.

[0106] Please refer to Figure 2 and ​ , the present application further provides that the workpiece feeding machine further comprises an open clamp assembly 600 installed on the feeding flow line 200, which is used to open the clamping structure on the tooling to allow the workpiece taking mechanism 20 to place the workpiece into the clamping structure on the tooling.

[0107] The open clamp assembly 600 is a device specially used to release or open the clamping structure on the tooling. Its function is to open the clamping structure on the tooling in advance before the workpiece is placed, creating conditions for the smooth placement of the workpiece. The open clamp assembly 600 can be implemented in various ways, for example, it can be a mechanical arm or a lever driven by a pneumatic cylinder or an electric push rod, which pushes or pulls the release mechanism of the clamping structure through physical contact; or it can also be an electromagnetic drive device, which attracts or repels specific components in the clamping structure through electromagnetic force to release the locked state. The open clamp assembly 600 is installed on the feeding flow line 200, ensuring that it can accurately interact with the tooling moving along the flow line. This installation method enables the open clamp assembly 600 to accurately operate the clamping structure of the tooling when it reaches the specified position.

[0108] Specifically, the open clamp assembly 600 can be fixedly installed on the side frame of the feeding line 200, and its height and position can be adjusted to adapt to the clamping structure of different toolings; or it can also be installed on the gantry structure above the feeding line 200, and it can contact and open the clamping structure through vertical movement. The core function of the open clamp assembly 600 is to open the clamping structure on the tooling. This means that it needs to have an interface or action mode that matches various clamping structures. For example, for a spring buckle type clamping structure, the open clamp assembly 600 can be designed as a wedge-shaped or hook-shaped component that inserts and spreads the buckle; for a rotary locking type clamping structure, the open clamp assembly 600 can be designed as a rotary driver that drives the unlocking component of the clamping structure to rotate to the open position. The purpose of the open clamp assembly 600 to open the clamping structure is to facilitate the placement of the workpiece by the material taking mechanism 20. This means that the action of the open clamp assembly 600 needs to be coordinated with the placement action of the material taking mechanism 20. For example, the open clamp assembly 600 can complete the opening action before the material taking mechanism 20 starts to descend to place the workpiece, and remain in the open state until the material taking mechanism 20 leaves after the workpiece is placed; or the opening action of the open clamp assembly 600 can be synchronized with the descending action of the material taking mechanism 20 to ensure that the clamping structure is in the open state when the workpiece contacts the tooling.

[0109] The workpiece feeding machine of the present application is provided with an open clamp assembly 600 on the feeding line 200. When the feeding line 200 carrying the empty tooling is transported to the preset feeding position, the open clamp assembly 600 is activated. The open clamp assembly 600 contacts and exerts force on the clamping structure on the tooling for fixing the workpiece through its specific structure, thereby opening the originally closed clamping structure. Once the clamping structure is opened, a space is created for the material taking mechanism 20 of the product material taking assembly to place the workpiece. At this time, the material taking mechanism 20 can accurately and without obstacles place the workpiece taken from the stock bin or other feeding position into the tooling with the opened clamping structure. In this way, the open clamp assembly 600 works with the feeding line 200 and the material taking mechanism 20 to ensure that the workpiece can be smoothly and efficiently placed into the tooling, avoiding the difficulty of placement or damage to the workpiece caused by the closed clamping structure, thereby realizing the automation and continuity of the entire feeding process.

[0110] Through the above technical solution, the open clamp assembly 600 is added to the workpiece feeding machine, which can automatically identify and open the clamping structure of the tooling on the feeding line 200. This effectively solves the technical problem that the material taking mechanism 20 cannot smoothly place the workpiece due to the closed clamping structure of the tooling during the workpiece placement process.

[0111] By pre-opening the clamping structure before placing the workpiece, it is ensured that the workpiece can be accurately and smoothly placed into the inside of the tool by the workpiece taking mechanism 20, interference and potential damage between the workpiece and the clamping structure are avoided, and the success rate and automation degree of workpiece feeding are significantly improved. At the same time, the need for manual intervention to open the clamping structure is eliminated, thereby improving the running efficiency of the entire feeding machine and the continuity of the production line.

Any equivalent structural transformation made by using the content of the present application specification and drawings, or direct / indirect application in other related technical fields under the technical concept of the present application is included in the patent protection scope of the present application.
