[0021] In order to make the technical problems, technical solutions and beneficial effects of the present application clearer, the present application will be further described in detail below in conjunction with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and not intended to limit the present application.

[0024] In addition, the terms "first", "second" are only for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined with "first", "second" can explicitly or implicitly include one or more of the features. In the description of the present application, the meaning of "a plurality of" is two or more, unless otherwise specifically limited.

[0025] In industrial production, it is often necessary to accurately position and reliably fix workpieces for subsequent processing, detection or transportation and other operations. The traditional positioning method may not meet the needs of simultaneous positioning of multiple workpieces and accurate positioning in different directions, which can easily lead to workpiece position deviation, affecting the processing quality and production efficiency. Therefore, it is necessary to design a load mechanism that can effectively position multiple workpieces in different directions, improve the accuracy and stability of positioning.

[0026] Please refer to Figure 1The carrier mechanism 10 provided in the embodiments of the present application will be described. The carrier mechanism 10 provided in the embodiments of the present application comprises a support assembly 11, a plurality of limiting assemblies 12, and a plurality of positioning assemblies 13. The support assembly 11 can carry a workpiece. Each limiting assembly 12 comprises two limiting pieces 121, which are arranged at intervals along a first direction on the support assembly 11. The first direction is denoted as X. Each positioning assembly 13 comprises a pressure receiving piece 131 and a pressing piece 132, which are arranged at intervals along a second direction on the support assembly 11. The second direction is denoted as Y. The pressing piece 132 is movably arranged along the second direction. The second direction has an included angle with the first direction. Each limiting assembly 12 and one positioning assembly 13 can position a workpiece. When the workpiece is placed between the two limiting pieces 121 and between the pressure receiving piece 131 and the pressing piece 132, the two limiting pieces 121 can limit the workpiece along the first direction, and the pressing piece 132 can move along the second direction to be close to the pressure receiving piece 131, so as to clamp and position the workpiece along the second direction together with the pressure receiving piece 131.

[0027] In the carrier mechanism 10 provided in the embodiments of the present application, the first direction and the second direction are used to describe the directional relationship of limiting and positioning. The two directions can be defined according to actual application scenarios, as long as they have an included angle. For example, the two directions can be perpendicular to each other.

[0028] The support assembly 11 serves as the basis of the entire carrier mechanism 10. The support assembly 11 provides a platform for carrying the workpiece, so as to ensure that the workpiece can be placed stably.

[0029] Each limiting assembly 12 comprises two limiting pieces 121 arranged at intervals along the first direction. When the workpiece is placed on the support assembly 11, the two limiting pieces 121 block the workpiece from both sides along the first direction, so as to limit the movement of the workpiece along the first direction, thereby achieving the positioning of the workpiece along the first direction.

[0030] Each positioning assembly 13 comprises a pressure receiving piece 131 and a pressing piece 132, which are arranged at intervals along the second direction on the support assembly 11. The pressing piece 132 is movable along the second direction. When the workpiece is placed between the pressure receiving piece 131 and the pressing piece 132, the pressing piece 132 is controlled to move towards the pressure receiving piece 131, so as to clamp the workpiece together with the pressure receiving piece 131 along the second direction, thereby achieving the positioning of the workpiece along the second direction. Since the first direction and the second direction have an included angle, usually a perpendicular relationship, the positioning of the workpiece in a two-dimensional plane can be achieved.

[0031] The plurality of limiting assemblies 12 and positioning assemblies 13 cooperate with each other. Each limiting assembly 12 and one positioning assembly 13 can independently position a workpiece, so as to achieve the simultaneous positioning of a plurality of workpieces, thereby improving the production efficiency and being suitable for the scene of batch production.

[0032] By limiting and clamping the workpiece in two different directions, the positional deviation of the workpiece in the plane can be effectively reduced, the positioning accuracy can be improved, and the requirements of high-precision machining and inspection can be met. At the same time, the constraint in two directions makes the workpiece more stable on the loading mechanism 10, less prone to shaking or displacement, ensuring the smooth progress of subsequent operations.

[0033] In actual implementation, on the battery cell processing production line, the support assembly 11 has a structure with a horizontal support platform, the limiting components 121 are two blocks mounted on the support platform, the pressure bearing component 131 is a block mounted on the support platform, and the pressing component 132 is a pressing block that can be driven by a cylinder or other driving components. The battery cell is placed between the two blocks and between the blocks and the pressing block, and the pressing block is driven to move closer to the blocks to achieve the positioning of the battery cell.

[0034] In the above embodiment, the limiting member 121 is configured to be adjustable along a first direction. By adjusting the position of the limiting member 121, the distance between the two limiting members 121 can be changed, thereby adapting to workpieces of different sizes. This enables the loading mechanism 10 to be compatible with a variety of workpieces of different sizes, reduces the need to replace the loading mechanism 10 due to changes in workpiece size, and improves production efficiency, utilization rate, and versatility.

[0035] The adjustable settings can be implemented in various ways, such as guide rail slider, screw and nut adjustment, or slot adjustment.

[0036] In practical implementation, the limiting component 121 can be mounted on the support assembly 11 via a guide rail and a slider. By tightening or loosening the bolts on the slider, the position of the limiting component 121 on the guide rail can be adjusted to accommodate mechanical parts of different widths. Alternatively, a bolt-and-strip hole method can be used. The limiting component 121 has a strip hole, and a bolt passes through the strip hole to connect to the support assembly 11. By tightening or loosening the bolt, the position of the limiting component 121 on the support assembly 11 can be adjusted.

[0037] Furthermore, in the above embodiment, the pressure-bearing member 131 is fixed to the support assembly 11 with screws as an example; the material loading mechanism 10 may also include a reinforcing member (not shown in the figure), the reinforcing member (not shown in the figure) is disposed on the side of the pressure-bearing member 131 away from the pressing member 132 along the second direction, the reinforcing member (not shown in the figure) is provided with an adjustment part (not shown in the figure) that is adjustable along the second direction, and the adjustment part (not shown in the figure) abuts against the side of the pressure-bearing member 131 away from the pressing member 132 along the second direction.

[0038] The pressure bearing 131 is fixed on the support assembly 11 by screws. When the pressing member 132 moves to push the workpiece to contact the pressure bearing 131, the pressure bearing 131 will be forced to generate a needle, and with frequent force vibration, the screws fixing the pressure bearing 131 will be loose, so that the pressure bearing 131 is not fixed firmly. The reinforcing member (not shown in the figure) is arranged on the side of the pressure bearing 131 away from the pressing member 132. The adjusting part (not shown in the figure) on the reinforcing member (not shown in the figure) abuts against the pressure bearing 131. Therefore, by adjusting the adjusting part (not shown in the figure), the side of the pressure bearing 131 away from the pressing member 132 is pressed, thereby resisting the force of the pressing member 132 and strengthening the stability of the pressure bearing 131. The stability and positioning accuracy of the pressure bearing 131 are improved, and the problem of inaccurate positioning of the workpiece caused by loosening or displacement of the pressure bearing 131 is reduced.

[0039] The adjusting part (not shown in the figure) can be a common screw or a precision screw with fine adjustment function, which is selected according to the actual requirement for positioning accuracy.

[0040] In actual implementation, the pressure bearing 131 is a positioning stop block fixed on the support assembly 11 by screws. The reinforcing member (not shown in the figure) is a block structure with a threaded hole. The adjustable screw abuts against the positioning stop block through the threaded hole. When the positioning stop block does not loosen, the force stability thereof can be improved by adjusting the adjustable screw. When the positioning stop block slightly displaces, the position thereof can be corrected by adjusting the adjustable screw.

[0041] Please refer to Figure 1 Further, the support assembly 11 in the above embodiment can include a support seat 111 and a plurality of bearing members 112. The plurality of bearing members 112 are arranged at intervals on the support seat 111, and each bearing member 112 can bear a workpiece. The two limiting members 121 of each set of limiting assemblies 12 are arranged on a bearing member 112, and the pressure bearing 131 of each set of positioning assemblies 13 is arranged on a bearing member 112. The pressing member 132 of the set of positioning assemblies 13 is movably connected to the bearing member 112 and / or the support seat 111 along the second direction.

[0042] By arranging the plurality of bearing members 112 at intervals, the load carrying mechanism 10 can simultaneously bear a plurality of workpieces, thereby improving the processing or transportation efficiency per unit time. The limiting and positioning of each workpiece are independently completed by the assemblies on the bearing member 112 where the workpiece is located, thereby avoiding mutual interference between different workpieces and ensuring the positioning accuracy of each workpiece. Each bearing member 112 and its corresponding limiting assembly 12 and positioning assembly 13 can be regarded as an independent module, which is convenient for maintenance, replacement or expansion, thereby improving the flexibility and maintainability of the equipment.

[0043] The support base 111 serves as a basic structure and provides mounting platforms for the plurality of bearing members 112. The spacing of the bearing members 112 ensures space utilization and avoids collision between workpieces.

[0044] Each set of limiting components 12 and positioning components 13 is centrally arranged on a single bearing member 112, making each bearing member 112 an independent functional unit. This design not only simplifies the overall structure but also facilitates the replacement of different bearing member 112 modules according to the size or type of workpieces.

[0045] The pressing member 132 can be connected to the bearing member 112 and / or the support base 111. This design takes into account both structural stability and movement flexibility. For example, if the pressing member 132 is only connected to the bearing member 112, the stress on the support base 111 can be reduced. If it is connected to the support base 111, the movement accuracy of the pressing member 132 can be ensured through the rigidity of the support base 111.

[0046] The design of multiple bearing members 112 allows simultaneous positioning of multiple workpieces, especially suitable for scenarios requiring batch processing or transportation, significantly improving production efficiency.

[0047] In actual implementation, the support base 111 is a base structure, and the plurality of bearing members 112 are arranged at uniform intervals on the support base 111. Each bearing member 112 is provided with a set of limiting components 12 and a pressure-bearing member 131. The pressing member 132 is a pressure block that can be driven by a gas cylinder or the like and can move in the second direction. When a workpiece is placed on a certain bearing member 112, the limiting components 12 limit the workpiece in the first direction, and the gas cylinder drives the pressure block to move, clamping the workpiece in cooperation with the pressure-bearing member 131 to achieve positioning. Multiple bearing members 112 can simultaneously carry different workpieces without interfering with each other.

[0048] Please refer to Figure 1 Furthermore, the above embodiment arranges the plurality of bearing members 112 in an array along the first direction and the second direction. This regular arrangement allows the bearing members 112 to have a clear positional relationship. In this layout, each bearing member 112 has a relatively fixed position coordinate. Whether it is the limiting of the workpiece in the first direction by the limiting components 12 or the positioning of the workpiece in the second direction by the positioning components 13, it can be done according to the established rules. Moreover, this layout is easier to interface with other production equipment (such as mechanical hands, conveyors, etc.). These devices can be programmed and set according to the array rules to achieve automated workpiece handling and processing, improving the automation level and efficiency of the entire production system.

[0049] And due to the standardization of array arrangement, it is convenient to design and plan the whole load mechanism 10, and it is also conducive to cooperate with the automatic feeding and discharging equipment, realize efficient workpiece carrying and positioning operation, reduce the complexity and failure rate of operation. At the same time, the array arrangement can make the carriers 112 closely and orderly arranged on the support seat 111, avoid the waste of space, and accommodate more carriers 112 in limited space, thereby improving the overall carrying capacity of the load mechanism 10.

[0050] The array arrangement is not limited to square or rectangular array, but also can be in the form of rhombus, hexagon and other forms according to actual needs. Different array forms are suitable for workpieces of different shapes and sizes, as well as different production sites and equipment layout. The first direction and the second direction can be flexibly defined according to the actual production scene. For example, in some cases, the first direction may be the direction of material flow on the production line, and the second direction is perpendicular to it; while in other cases, the two directions may be related to the installation direction of the equipment or the operation habit of the operator.

[0051] Among them, the array arrangement of the carrier 112 also has good expansibility, for example, if the number of carriers 112 needs to be increased, it only needs to be expanded on the basis of the original array, without the need for large-scale modification of the whole load mechanism 10, which is convenient for the expansion and adjustment of production scale.

[0052] In actual implementation, taking the case where the first direction and the second direction are perpendicular to each other as an example, a plurality of carriers 112 are arranged in a matrix array on the support seat 111 along the first direction and the second direction. For example, there are 10 carriers 112 arranged along the first direction, and 8 carriers 112 arranged along the second direction, which can simultaneously carry a total of 80 workpieces. The automatic feeding and discharging manipulator can accurately place the workpieces on the specified carrier 112 according to the array standard, or take the processed workpieces from the carrier 112

[0053] Please refer to Figure 1 and Figure 2 , further, the positioning assembly 13 in the above embodiment can further include an elastic member 133, the elastic member 133 elastically connecting the pressing member 132 and the support seat 111, the pressing member 132 being movable under the elastic driving action of the elastic member 133, pressing the workpiece and cooperating with the pressure receiving member 131 to clamp and position the workpiece along the second direction.

[0054] When the workpiece is placed between the pressure receiving member 131 and the pressing member 132, the pressing member 132 will automatically move towards the pressure receiving member 131 along the second direction under the driving action of the elasticity of the elastic member 133 itself until the workpiece is pressed on the pressure receiving member 131 and cooperates with the pressure receiving member 131 to clamp and position the workpiece in the second direction. When the workpiece needs to be removed, the pressing member 132 is moved away from the pressure receiving member 131 against the elasticity of the elastic member 133, so that the workpiece is no longer clamped, and the workpiece removal operation is completed.

[0055] The arrangement of the elastic member 133 driving the pressing member 132 does not require an additional power source (such as a motor, air cylinder, etc.) and a complex control device to drive the pressing member 132 to clamp the workpiece, thereby reducing the number of parts and complexity, and reducing the cost and maintenance difficulty. Only by placing the workpiece in the corresponding position, the pressing member 132 can automatically complete the clamping and positioning under the action of the elastic member 133, and the operation is more convenient and fast.

[0056] Moreover, since the clamping action of the pressing member 132 is automatically completed, the manual intervention and operation time are reduced, and especially in the production line which needs to frequently carry out feeding and discharging, the production efficiency can be significantly improved.

[0057] In addition, the elasticity of the elastic member 133 can be adjusted according to the size and clamping force requirement of the workpiece, so that the workpiece loading mechanism 10 can adapt to workpieces of different sizes and shapes, and the versatility and adaptability are improved.

[0058] Among them, the elastic member 133 can have multiple types, in addition to the common springs (such as coil springs, disc springs, etc.), it can also be a rubber elastic body, an elastic plastic, etc., and the specific embodiments of the present application are not limited, and they are all applicable.

[0059] In actual implementation, the elastic member 133 takes a spring as an example, one end of the spring is connected to the pressing member 132, and the other end is connected to the support seat 111. When the workpiece is placed between the pressure receiving member 131 and the pressing member 132, the elasticity of the spring automatically moves the pressing member 132 towards the pressure receiving member 131 to clamp and position the workpiece. When the machining is completed, the operator uses fingers or a driving cylinder to remove the workpiece to drive the pressing member 132 to move against the elasticity of the spring, and the workpiece can be removed.

[0060] Please refer to Figure 1 and Figure 2 Further, the workpiece loading mechanism 10 in the above embodiment can further include a guide shaft 15 and a connecting member 16. The guide shaft 15 is arranged in the second direction along the axial direction of the support seat 111. The pressing members 132 adjacent in the second direction are connected and fixed by the connecting member 16, and are movably connected with the guide shaft 15 in the second direction.

[0061] The axial direction of the guide shaft 15 is fixed on the support seat 111 in the second direction, providing an accurate guide path for the movement of the pressing piece 132. Adjacent pressing pieces 132 in the second direction are connected and fixed by a connecting piece 16 (such as a connecting plate, a connecting rod, etc.), forming a synchronous linkage structure. These pressing pieces 132 are movably connected with the guide shaft 15 in the second direction (for example, through a sliding block, a bearing, etc.), so that when one of the pressing pieces 132 is driven, the connecting piece 16 will drive all adjacent pressing pieces 132 to move synchronously along the guide shaft 15. This design ensures the consistency of the movement of multiple pressing pieces 132 in the second direction, thereby ensuring that the clamping force on multiple workpieces is uniform and the positioning position is unified, avoiding problems such as workpiece position deviation or clamping instability caused by individual pressing piece 132 movement deviation.

[0062] The guide shaft 15 provides rigid support for the movement of the pressing piece 132, reducing shaking and deviation during movement, and improving the structural stability and reliability of the entire load mechanism 10. When the elastic piece 133 is a spring, the spring is sleeved on the guide shaft 15.

[0063] The guide shaft 15 serves as a guide structure for the movement of the pressing piece 132, and the material and structural design of the guide shaft 15 (such as using a high-strength metal shaft, surface chrome plating treatment, etc.) can improve its wear resistance and corrosion resistance, prolonging the service life.

[0064] The connecting piece 16 physically connects multiple pressing pieces 132 into a whole, making their movements completely synchronized. The rigidity and strength of the connecting piece 16 directly affect the linkage effect, and appropriate materials (such as metal plates, profiles, etc.) and structural forms (such as straight plates, truss structures, etc.) need to be selected according to the actual stress situation. The design of the connecting piece 16 also needs to consider the connection method with the pressing piece 132 and the guide shaft 15, such as through bolt fastening, welding or buckle connection, etc., to ensure the reliability of the connection

[0065] The embodiments of the present application are particularly suitable for scenarios that require simultaneous parallel clamping of multiple workpieces, such as plate processing, multi-station assembly, etc. By adjusting the number, spacing of the guide shaft 15 and the length of the connecting piece 16, different sizes and layouts of workpieces can be flexibly adapted. On an automated production line, the combination of the guide shaft 15 and the connecting piece 16 also facilitates integration with a driving device (such as a motor, an air cylinder), achieving efficient automated clamping and loosening operations.

[0066] In actual implementation, multiple guide shafts 15 are arranged in parallel on the support seat 111 in the second direction, a sliding block is sleeved on each guide shaft 15, adjacent pressing pieces 132 are fixedly connected by a connecting piece 16, and the pressing piece 132 is connected with the sliding block. When one of the pressing pieces 132 is driven to move along the guide shaft 15, the connecting piece 16 drives all adjacent pressing pieces 132 to move synchronously, clamping the workpiece.

[0067] Please refer to Figure 1 and Figure 2 Further, the first direction and the second direction are defined as parallel to the horizontal plane and perpendicular to each other, and the adjacent pressing pieces 132 along the second direction are respectively a first pressing piece 1321 and a second pressing piece 1322, the corresponding carrier 112 of the first pressing piece 1321 is a first carrier 1121, and the corresponding carrier 112 of the second pressing piece 1322 is a second carrier 1122, and the first carrier 1121 and the second carrier 1122 are horizontally arranged; the first pressing piece 1321 is arranged at one end of the first carrier 1121 along the second direction, and the second pressing piece 1322 is arranged at the other end of the first carrier 1121 along the second direction and located between the first carrier 1121 and the second carrier 1122, and the guide shaft 15 and the connecting piece 16 are arranged from below the first carrier 1121; the elastic piece 133 is arranged on the side of the first pressing piece 1321 away from the first carrier 1121 along the second direction, and the elastic piece 133 can drive the first pressing piece 1321 and the second pressing piece 1322 to move synchronously along the first direction.

[0068] The first carrier 1121 and the second carrier 1122 are horizontally arranged, the first pressing piece 1321 is arranged at one end of the first carrier 1121 along the second direction, and the second pressing piece 1322 is arranged at the other end of the first carrier 1121 along the second direction and located between the first carrier 1121 and the second carrier 1122. The guide shaft 15 and the connecting piece 16 are arranged from below the first carrier 1121, and the pressing pieces 132 are reasonably arranged, so that the overall structure of the material carrying mechanism 10 is more compact, the occupied space of the equipment on the horizontal plane is reduced, and it is suitable for use in a production environment with limited space.

[0069] The elastic piece 133 is arranged on the side of the first pressing piece 1321 away from the first carrier 1121 along the second direction, and when the elastic piece 133 generates elastic force, it will drive the first pressing piece 1321 to move along the first direction. Since the first pressing piece 1321 and the second pressing piece 1322 are connected by the connecting piece 16, the movement of the first pressing piece 1321 will drive the second pressing piece 1322 to move synchronously along the first direction. In this way, the first pressing piece 1321 and the second pressing piece 1322 can clamp and position the workpieces on the first carrier 1121 and the second carrier 1122 respectively. Through the driving of the elastic piece 133 and the connection of the connecting piece 16, the first pressing piece 1321 and the second pressing piece 1322 can move synchronously, ensuring that the workpieces on the adjacent carriers 112 are clamped and positioned at the same time, improving the consistency and accuracy of positioning.

[0070] The first carrier 1121 and the second carrier 1122 can be various forms of carriers such as trays, clamps, etc., and the specific form depends on the shape, size and characteristics of the workpiece. Meanwhile, the number of carriers 112 can also be expanded according to actual needs, and more workpieces can be positioned through similar layout and connection mode.

[0071] The layout disclosed in the embodiments of the present application makes the feeding and discharging operation more convenient, and the operator or automatic equipment can more easily access the carrier 112 to place and take out the workpiece.

[0072] Please refer to Figure 1 and Figure 2 Specifically, the second pressing member 1322 in the above embodiment can include a pressing part 1322a and a fixed part 1322b, the first pressing member 1321 is connected with the fixed part 1322b through the connecting member 16, and the first pressing member 1321 and the fixed part 1322b are both slidably connected with the guide shaft 15 along the second direction; the pressing part 1322a is movably arranged in the fixed part 1322b along the second direction, and the elastic member 133 is arranged between the pressing part 1322a and the fixed part 1322b along the second direction; the pressing part 1322a is driven by the elastic force of the elastic member 133 to moveably press the workpiece carried by the second carrier 1122, and cooperates with the corresponding pressing member 131 to clamp and position the workpiece along the second direction.

[0073] The fixed part 1322b of the first pressing member 1321 and the second pressing member 1322 is connected through the connecting member 16, and they are both slidably connected with the guide shaft 15 along the second direction, which makes the fixed part 1322b of the first pressing member 1321 and the second pressing member 1322 can move along the second direction under the guidance of the guide shaft 15.

[0074] The pressing part 1322a of the second pressing member 1322 is movably arranged on the fixed part 1322b along the second direction, and the elastic member 133 is arranged therebetween. When the fixed part 1322b of the first pressing member 1321 and the second pressing member 1322 moves under the action of the elastic member 133 (the elastic member 133 arranged on the side of the first pressing member 1321 away from the first carrier 1121 drives them to move as a whole), the pressing part 1322a will be driven by the elastic force of the elastic member 133 between the pressing part 1322a and the fixed part 1322b to move independently relative to the fixed part 1322b according to the specific situation of the workpiece contacted, so as to realize self-adaptive clamping and positioning of the workpiece carried by the second carrier 1122, and cooperate with the corresponding pressing member 131 to accurately clamp the workpiece along the second direction.

[0075] In this way, the workpieces on the different bearing members 112 can be precisely clamped and positioned according to the size, shape, and other differences of the workpieces. Even if there are slight differences between adjacent workpieces, the pressing part 1322a can automatically adjust the position and clamping force through the action of the elastic member 133, avoiding the problem of inaccurate positioning caused by differences in workpieces. Moreover, since the pressing part 1322a can be adaptively adjusted according to the workpiece situation, damage caused by excessive clamping of the workpiece can be effectively avoided, protecting the integrity and surface quality of the workpiece. The adaptability of the material loading mechanism 10 to different types and specifications of workpieces is enhanced, and frequent replacement of the pressing structure for different workpieces is not required, improving the versatility and use efficiency of the equipment.

[0076] The movable arrangement of the pressing part 1322a along the second direction to the fixed part 1322b can have various forms, such as through a guide rail and slider structure, a sliding groove cooperation, etc., to ensure the stability and accuracy of the movement of the pressing part 1322a. Different connection methods are suitable for different working environments and precision requirements.

[0077] The elastic coefficient and pre-tightening force of the elastic member 133 can be adjusted according to actual needs. For soft or fragile workpieces, a smaller elastic member 133 with a smaller elastic coefficient can be selected to provide a smaller and softer clamping force; for workpieces with higher hardness, the elastic coefficient or pre-tightening force can be appropriately increased to ensure sufficient clamping effect.

[0078] The embodiment of the present application also provides a processing equipment (not shown in the figure), which includes a feeding and discharging mechanism (not shown in the figure), a driving mechanism (not shown in the figure), and the material loading mechanism 10 in any of the above embodiments. The driving mechanism (not shown in the figure) is drivably connected with the pressing member 132, and the driving mechanism (not shown in the figure) can drive the pressing member 132 to move along the second direction. The driving mechanism (not shown in the figure) drives the pressing member 132 to move away from the corresponding pressure-bearing member 131 along the second direction. The feeding and discharging mechanism (not shown in the figure) can place the workpiece between the pressure-bearing member 131 and the pressing member 132, or take the workpiece away from between the pressure-bearing member 131 and the pressing member 132. The laser marking equipment of the embodiment of the present application includes the material loading mechanism 10 in any of the above embodiments, and thus has the beneficial effects brought by the material loading mechanism 10 in any of the above embodiments, which will not be repeated here.

[0079] The driving mechanism (not shown in the figure) is drivingly connected with the pressing piece 132 in the material carrying mechanism 10. When the feeding operation is needed, the driving mechanism (not shown in the figure) drives the pressing piece 132 to move away from the corresponding pressure receiving piece 131 in the second direction. At this time, the feeding and discharging mechanism (not shown in the figure) places the workpiece to be processed between the pressure receiving piece 131 and the pressing piece 132. Then, the driving mechanism (not shown in the figure) reversely drives the pressing piece 132 to move close to the pressure receiving piece 131 in the second direction, and cooperates with the pressure receiving piece 131 to clamp and position the workpiece, so as to carry out subsequent processing. Of course, in combination with the arrangement of the elastic piece 133, when the workpiece is clamped and positioned, the driving mechanism (not shown in the figure) only needs to be disconnected with the pressing piece 132, and the pressing piece 132 automatically clamps and positions the workpiece under the elastic force of the elastic piece 133. When the processing is completed, the driving mechanism (not shown in the figure) drives the pressing piece 132 away from the pressure receiving piece 131 again, and the feeding and discharging mechanism (not shown in the figure) takes away the processed workpiece from between the pressure receiving piece 131 and the pressing piece 132.

[0080] The movement of the pressing piece 132 is controlled by the driving mechanism (not shown in the figure), and the feeding and discharging mechanism (not shown in the figure) cooperates to realize the automatic feeding and discharging and positioning and clamping of the workpiece, reduces the manual intervention, and improves the automation degree of the whole processing process.

[0081] The driving mechanism (not shown in the figure) can adopt various forms, in addition to a servo motor, and can also be a pneumatic cylinder, a hydraulic cylinder, etc. Different driving mechanisms (not shown in the figure) have different characteristics and application scenarios. For example, the pneumatic cylinder has the advantages of fast response speed and simple structure, and is suitable for occasions with high speed requirements; the hydraulic cylinder has the characteristics of large output force, and is suitable for situations requiring large clamping force.

[0082] The form of the feeding and discharging mechanism (not shown in the figure) can be selected according to the shape, size and weight of the workpiece. In addition to industrial robots, it can also be a conveyor belt, an elevator, etc. For small and regular-shaped workpieces, the conveyor belt can realize continuous feeding and discharging operation; for large and heavy workpieces, the elevator is more suitable for carrying.

[0083] The above only describes the preferred embodiments of the present application and is not used to limit the present application. Any modification, equivalent replacement and improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application.
