[0050] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative efforts fall within the protection scope of the present application.

[0051] The present application provides a pickup device 10. Please refer to Figures 1 to 3 , Figure 1 which is the overall structure schematic diagram of the pickup device provided in the exemplary embodiment of the present disclosure, Figure 2 is Figure 1 the structure schematic diagram of the pickup device (at an angle) shown in Figure 3 is Figure 2 the partial enlarged schematic diagram at position A in

[0052] The pickup device 10 includes a base 1 and a pickup unit 2. The pickup unit 2 includes an adsorption assembly 201 and a clamping assembly 202.

[0053] It should be noted that the shape of the base 1 is not limited in this application, and the specific shape of the base 1 can be set according to needs, and this application does not limit it. In addition, in the embodiments of this application, the length direction, width direction, and thickness direction of the base are relative directions.

[0054] Refer to Figure 5 , Figure 5 is Figure 1 the left view schematic diagram of the picking device shown, and the adsorption component 201 is movably installed on the base 1 along the first direction, and the adsorption component 201 is used to selectively adsorb the component to be picked up.

[0055] It should be noted that when it is necessary to adsorb the component 200 to be picked up, the end of the adsorption component 201 is located above or near the component 200 to be picked up, and the adsorption component 201 uses its end device to generate negative pressure to firmly adsorb the component 200 to be picked up. This non-contact or low-contact adsorption method helps to reduce damage to the component 200 to be picked up and is applicable to components 200 to be picked up of various materials and shapes. In addition, the effectiveness of the adsorption function depends on the design of the adsorption device, the magnitude of the suction force, and the material and weight of the component 200 to be picked up.

[0056] Refer to Figure 5 , the clamping component 202 is installed on the base 1, and the clamping component 202 is used to clamp the component 200 to be picked up adsorbed by the adsorption component 201 when the adsorption component 201 moves to a preset position.

[0057] It should be noted that there is an accurate positional cooperation relationship between the clamping component 202 and the adsorption component 201. When the adsorption component 201 moves the component 200 to be picked up to a preset position, the clamping component 202 can accurately capture the component 200 to be picked up and apply the necessary clamping force to clamp the component 200 to be picked up.

[0058] Specifically, there are various types of components 200 to be picked up. For example, in one embodiment, the component 200 to be picked up may include electronic products such as mobile phones, display screens, or laptop computers. In other embodiments, the component 200 to be picked up may include machined parts. The types of components 200 to be picked up can be set according to needs, and this application does not limit it.

[0059] In the picking device 10 according to the embodiment of the present application, first, the component 200 to be picked is firmly adsorbed on the adsorption assembly 201 by negative pressure or other suction mechanisms. This non-contact adsorption method avoids the damage that may be caused by mechanical clamping and ensures the stability of the component 200 to be picked in the initial picking stage. Subsequently, when the adsorption assembly 201 moves the component 200 to be picked to a preset position, the clamping assembly 202 intervenes and further clamps and fixes the component 200 to be picked mechanically. This dual-action mechanism of first adsorbing and then clamping ensures the stability of the component 200 to be picked during the entire transfer process. At the same time, it enables the picking device 10 to stably pick more types of components 200 to be picked, improving the flexibility and diversity of the picking operation. Even if there are slight suction fluctuations or component position offsets during the adsorption process, the clamping assembly 202 can compensate in time to prevent the component 200 to be picked from falling off. Since the adsorption assembly 201 and the clamping assembly 202 can be independently controlled and cooperate with each other, this makes the picking process more precise. The adsorption assembly 201 can accurately adjust the adsorption position as needed, while the clamping assembly 202 can immediately clamp after the component 200 to be picked reaches the preset position, reducing the picking failure caused by position deviation. Due to the flexibility and adjustability of the adsorption assembly 201 and the clamping assembly 202, this picking device 10 can be applied to pick components 200 to be picked with various shapes, sizes, and materials. By adjusting the suction force of the adsorption assembly 201 and the clamping force of the clamping assembly 202, precise picking of different components 200 to be picked can be achieved.

[0060] Referring to Figures 4 to 6 , Figure 4 is Figure 1 the front view schematic diagram of the picking device shown, Figure 5 is Figure 1 the left view schematic diagram of the picking device shown, Figure 6 is Figure 1A cross-sectional schematic view of the shown picking device. In some embodiments, the clamping assembly 202 includes a first clamping portion 23 and a second clamping portion 24 arranged at intervals along the third direction. At least one of the first clamping portion 23 and the second clamping portion 24 is movably mounted on the base 1, so that the first clamping portion 23 and the second clamping portion 24 are adapted to approach each other to clamp the component 200 to be picked up or move away from each other to release the component 200 to be picked up. Thus, by precisely controlling the movement of at least one of the first clamping portion 23 and the second clamping portion 24, high-precision positioning and clamping of the component 200 to be picked up can be achieved. Since at least one of the first clamping portion 23 and the second clamping portion 24 is movable, they can be adjusted according to the size and shape of the component 200 to be picked up, so as to adapt to the clamping requirements of different specifications and types of components 200 to be picked up. Through the cooperation of the first clamping portion 23 and the second clamping portion 24, the component 200 to be picked up can be clamped more firmly, avoiding accidental dropping or damage of the component 200 to be picked up during processing, transportation or assembly. By controlling the movement of at least one of the first clamping portion 23 and the second clamping portion 24, rapid clamping and release of the component 200 to be picked up can be achieved, simplifying the operation process and improving production efficiency.

[0061] In some embodiments, both the first clamping portion 23 and the second clamping portion 24 are slidably mounted on the base along the third direction. Thus, by driving the first clamping portion 23 and the second clamping portion 24 to slide, the relative position between the first clamping portion 23 and the second clamping portion 24 can be adjusted smoothly, and rapid clamping and rapid release of the component 200 to be picked up with different sizes, shapes and materials can be achieved, improving the versatility and utilization rate of the clamping assembly 202. The first clamping portion 23 and the second clamping portion 24 slide along the third direction, which helps to ensure the stability and reliability of the clamping portion during the clamping process and improve the operating efficiency of the whole system. The design of the sliding mounting of the first clamping portion 23 and the second clamping portion 24 is simple in structure, which is beneficial to the cleaning and maintenance work, and reduces the maintenance difficulty and cost caused by the complex structure.

[0062] It should be noted that one of the base 1 and the first clamping portion 23 is provided with a first sliding portion extending along the third direction, and the other of the base 1 and the first clamping portion 23 is provided with a first mating portion slidably engaged with the first sliding portion. Through the cooperation of the first sliding portion and the first mating portion, the sliding fit between the base 1 and the first clamping portion 23 can be achieved. One of the base 1 and the second clamping portion 24 is provided with a second sliding portion extending along the third direction, and the other of the base 1 and the second clamping portion 24 is provided with a second mating portion slidably engaged with the second sliding portion. Through the cooperation of the second sliding portion and the second mating portion, the sliding fit between the base 1 and the second clamping portion 24 can be achieved.

[0063] Specifically, in one embodiment, the first sliding portion includes a second chute, and the first mating portion includes a second sliding table. In another embodiment, the first sliding portion includes a second sliding column, and the first mating portion includes a second through hole. The specific settings of the first sliding portion and the first mating portion can be selected as needed, and the present application does not limit this. In one embodiment, the second sliding portion includes a third chute, and the second mating portion includes a third sliding table. In another embodiment, the second sliding portion includes a third sliding column, and the second mating portion includes a third through hole. The specific settings of the second sliding portion and the second mating portion can be selected as needed, and the present application does not limit this.

[0064] Referring to Figure 5 and Figure 6 , in some embodiments, the picking device 10 further includes a first driving assembly 5. The first driving assembly 5 is installed on the base 1 and is used to drive the first clamping portion 23 and / or the second clamping portion 24 to move. In this way, the introduction of the first driving assembly 5 automates the process of clamping and releasing the component 200 to be picked, reduces the need for manual intervention, improves the clamping efficiency and automation level, and reduces the labor intensity of workers. By integrating the first driving assembly 5 and the clamping assembly 202 on the same base 1, a more compact and efficient picking device 10 can be constructed, which is convenient for installation, debugging, and maintenance. According to the size, shape, and position changes of the component 200 to be picked, the first driving assembly 5 can adjust the positions of the first clamping portion 23 and / or the second clamping portion 24 in real time, maintain a stable clamping force, and prevent the component 200 to be picked from moving or falling off during the clamping process. The first driving assembly 5 usually has a high response speed and can quickly complete the clamping and releasing actions, shorten the clamping cycle, and improve the clamping efficiency.

[0065] It should be noted that the driving ability of the first driving assembly 5 can be adjusted according to the requirements of different components 200 to be picked to adapt to the clamping requirements of components of different sizes, shapes, and weights.

[0066] Referring to Figure 6, in some embodiments, the first driving assembly 5 includes a clamping cylinder 51. The clamping cylinder 51 includes a cylinder body mounted on the base 1 and two piston rods 511 movably mounted in the cylinder body. The two piston rods 511 have a moving stroke of approaching or separating from each other along the third direction. One of the two piston rods 511 is connected to the first clamping portion 23, and the other of the two piston rods 511 is connected to the second clamping portion 24. Thus, the clamping cylinder 51 generally has a high response speed. The clamping cylinder 51 controls the movement of the first clamping portion 23 and the second clamping portion 24 through the two piston rods 511, enabling the first clamping portion 23 and the second clamping portion 24 to quickly complete the clamping and releasing actions, thereby improving the clamping efficiency. The moving stroke of the two piston rods 511 along the third direction can be precisely adjusted as needed to adapt to workpieces 200 to be picked up with different sizes and shapes, improving the flexibility and adaptability of the clamping of the clamping assembly 202. In addition, the structure of the clamping cylinder 51 is relatively simple, making its installation, debugging, and maintenance operations simple and convenient. Moreover, since the clamping cylinder 51 has high reliability and durability, the maintenance cost of the picking device 10 can be reduced to a certain extent.

[0067] It should be noted that the clamping cylinder 51 generally has stronger versatility and adaptability, can handle a wider range of workpiece types and sizes, reduces the frequency of replacement and adjustment, and thus improves the work efficiency. The addition of the clamping cylinder 51 increases the complexity of the clamping assembly 202, but this also brings higher operation stability and precision. At the same time, with the continuous development of automation technology, the manufacturing cost of the clamping cylinder 51 is also continuously decreasing, making the picking device 10 gradually become feasible and competitive in terms of cost. The clamping cylinder 51 is usually equipped with a precise control system, which can ensure the accuracy of clamping and releasing and meet the requirements of high-precision machining and testing.

[0068] Refer to Figure 4 and Figure 6, in some embodiments, the first clamping portion 23 has a first clamping surface facing the second clamping portion 24, and a first flexible member 6 is provided on the first clamping surface. The first flexible member 6 is used for flexible abutment with the component 200 to be picked up. Thus, the first flexible member 6 serves as a buffer layer during the clamping process, and can effectively reduce the direct contact between the first clamping portion 23 and the component 200 to be picked up, thereby avoiding scratches, indentations or other forms of damage that may be caused by rigid contact. The first flexible member 6 can adapt to the irregularities and minute changes on the surface of the component 200 to be picked up, ensuring uniform force application during the clamping process and reducing clamping instability or failure caused by surface unevenness. The flexible contact between the first flexible member 6 and the component 200 to be picked up can increase the contact area, thereby increasing the frictional force to a certain extent and helping to prevent the component 200 to be picked up from sliding or falling off during the clamping process. During the clamping process, if the position or shape of the component 200 to be picked up changes slightly, the first flexible member 6 can deform accordingly and maintain close contact with the component 200 to be picked up, ensuring the stability of the clamping. The first flexible member 6 serves as a buffer layer during the clamping process, and can reduce the direct wear between the first clamping portion 23 and the component 200 to be picked up, thereby extending the service life of the clamping assembly. Since the possibility of wear and damage is reduced, the maintenance cost and replacement frequency of the clamping assembly are also reduced.

[0069] It should be noted that there are various materials for making the first flexible member 6. For example, the materials for making the first flexible member 6 may include rubber, silica gel, sponge or memory foam, etc. Specifically, the materials for making the first flexible member 6 can be selected according to needs, and the present application does not limit this.

[0070] Refer to Figure 4 and Figure 6, in some embodiments, the second clamping portion 24 has a second clamping surface facing the first clamping portion 23, and the second clamping surface is provided with a second flexible member 7. The second flexible member 7 is used for flexible abutment with the component 200 to be picked up. Thus, the second flexible member 7 serves as a buffer layer during the clamping process, and can effectively reduce the direct contact between the second clamping portion 24 and the component 200 to be picked up, thereby avoiding scratches, indentations or other forms of damage that may be caused by rigid contact. The second flexible member 7 can adapt to the irregularities and minor changes on the surface of the component 200 to be picked up, ensure uniform force application during the clamping process, and reduce clamping instability or failure caused by surface unevenness. The flexible contact between the second flexible member 7 and the component 200 to be picked up can increase the contact area, thereby increasing the frictional force to a certain extent and helping to prevent the component 200 to be picked up from sliding or falling off during the clamping process. During the clamping process, if the position or shape of the component 200 to be picked up changes slightly, the second flexible member 7 can deform accordingly and maintain close contact with the component 200 to be picked up, ensuring the stability of the clamping. The second flexible member 7 serves as a buffer layer during the clamping process, can reduce the direct wear between the second clamping portion 24 and the component 200 to be picked up, thereby extending the service life of the clamping assembly. Since the possibility of wear and damage is reduced, the maintenance cost and replacement frequency of the clamping assembly are also reduced.

[0071] It should be noted that there are various materials for making the second flexible member 7. For example, the materials for making the second flexible member 7 may include rubber, silica gel, sponge or memory foam, etc. Specifically, the materials for making the second flexible member 7 can be selected according to needs, and this application does not limit this.

[0072] Continue to refer to Figure 1 、 Figure 2 and Figure 5, in some embodiments, the adsorption assembly 201 includes a mounting portion 21 and at least two adsorption portions 22. The mounting portion 21 is movably mounted on the base 1 along a first direction. The at least two adsorption portions 22 are mounted on the mounting portion 21. The at least two adsorption portions 22 are arranged at intervals along a second direction. Each adsorption portion 22 is configured to selectively adsorb the component 200 to be picked up. The first direction is perpendicular to the second direction. In this way, the distance between the mounting portion 21 and the base 1 can be adjusted as needed, so that each adsorption portion 22 is adapted to selectively adsorb the component 200 to be picked up at different heights or depths, thereby greatly improving the adaptability of the picking device 10. The at least two adsorption portions 22 are arranged at intervals along the second direction, so that the at least two adsorption portions 22 can perform adsorption operations on different positions of a single component 200 to be picked up. Using the at least two adsorption portions 22 can disperse the load, reduce the pressure on a single adsorption portion 22, and reduce the risk of damage to the component 200 to be picked up. In addition, the at least two adsorption portions 22 can also adsorb the component 200 to be picked up respectively. In this way, the adsorption efficiency is improved. Since different components 200 to be picked up may have different shapes and sizes. The design of the at least two adsorption portions 22 enables the adsorption assembly 201 to more easily adapt to these changes to match the adsorption requirements of different components 200 to be picked up. In some cases, if one of the adsorption portions 22 fails or cannot work properly, the other adsorption portion 22 can still continue to perform the adsorption operation, thus ensuring the reliability and continuity of the adsorption assembly 201.

[0073] Refer to Figure 3 and Figure 5 , in some embodiments, the mounting portion 21 and the base 1 are connected by a guiding structure. The guiding structure includes a guiding portion 81 extending along the first direction and a mating portion 82 slidably engaged with the guiding portion 81. One of the guiding portion 81 and the mating portion 82 is provided on the mounting portion 21, and the other is provided on the base 1. In this way, since the guiding portion 81 and the mating portion 82 are slidably engaged, the mounting portion 21 is allowed to move relatively flexibly with respect to the base 1 along the first direction to adapt to different working conditions and position requirements. When subjected to an external force, the sliding engagement can disperse the stress over a larger contact surface, reducing the risk of damage to the mounting portion 21 and the base 1 caused by stress concentration.

[0074] It should be noted that there are various guiding parts 81 and mating parts 82. For example, in one embodiment, the guiding part 81 includes a first sliding groove extending along the first direction, and the mating part 82 includes a first sliding table. The cooperation between the first sliding groove and the first sliding table realizes the sliding cooperation between the mounting part 21 and the base 1. In another embodiment, the guiding part 81 includes a first through hole extending along the first direction, and the mating part 82 includes a first sliding column. The sliding cooperation between the first sliding column and the first through hole realizes the sliding cooperation between the mounting part 21 and the base 1. Specifically, the types of the guiding part 81 and the mating part 82 can be set according to needs, and the present application does not limit this.

[0075] Referring to Figure 1 and Figure 2 , in some embodiments, each adsorption part 22 includes at least two suction nozzles 221 arranged at intervals along the third direction on the mounting part 21. Each suction nozzle 221 is used to adsorb the component 200 to be picked up. The first direction, the second direction, and the third direction are perpendicular to each other pairwise. In this way, by arranging a plurality of suction nozzles 221 at intervals along the length direction on the base 1, on the one hand, a plurality of suction nozzles 221 can simultaneously adsorb a plurality of components 200 to be picked up, thereby significantly improving the picking efficiency. On the other hand, a plurality of suction nozzles 221 can simultaneously adsorb different positions of the same component 200 to be picked up, so that the force on the component 200 to be picked up is more dispersed when being adsorbed, which helps to enhance the overall adsorption stability of the component 200 to be picked up. Even when facing components with irregular shapes or uneven center of gravity distributions, it can effectively avoid adsorption failure or component damage caused by uneven single-point force. The arrangement of a plurality of suction nozzles 221 enables a single suction nozzle 221 to be replaced separately without affecting the operation of the entire adsorption assembly 201 when a certain suction nozzle 221 fails.

[0076] Continuing to refer to Figure 1 and Figure 2, in some embodiments, any suction nozzle 221 is adapted to be slidably mounted on the mounting portion 21 along the third direction or the second direction. Thus, this design enables the suction nozzle 221 to flexibly adjust its position as needed. Whether along the third direction or the second direction, fine adjustments can be made according to the specific position and shape of the component 200 to be picked up, so as to adapt to different working scenarios. This flexibility greatly improves the adaptability and picking efficiency of the picking device 10. By slidably mounting the suction nozzle 221, it is easier to achieve an optimized layout among multiple suction nozzles 221. According to the distribution of the components 200 to be picked up, the spacing between the suction nozzles 221 can be adjusted to ensure that each suction nozzle 221 can accurately and efficiently pick up the components 200 to be picked up, avoiding resource waste and picking conflicts. When facing components 200 to be picked up with different sizes, shapes or arrangements, the slidably mounted suction nozzle 221 can adapt to the changes more quickly. By adjusting the position and angle of the suction nozzle 221, it can be ensured that the device can always maintain the best picking state, thereby improving the picking efficiency and product quality. The slidably mounted suction nozzle 221 can improve the picking accuracy through precise position adjustment. During the picking process, the suction nozzle 221 can be finely adjusted according to the specific position and shape of the component 200 to be picked up to ensure that the suction nozzle 221 can accurately contact the component and stably adsorb it.

[0077] It should be noted that the driving method for driving the suction nozzle 221 to slide for position adjustment can be manual driving or driving by a driving mechanism. The driving mechanism can include a cylinder or an electric push rod. Specifically, the method for driving the suction nozzle 221 to slide can be selected according to needs, and the present application does not limit this.

[0078] Refer to Figure 1, in one embodiment, the mounting portion 21 is provided with a sliding structure. The sliding structure includes a first elongated hole 211 and a second elongated hole 212 penetrating therethrough in a first direction. The first elongated hole 211 extends in a third direction, and the second elongated hole 212 extends in a second direction. Wherein, any suction nozzle 221 is slidably mounted in the first elongated hole 211 or the second elongated hole 212. Thus, through the design of the first elongated hole 211 and the second elongated hole 212, any suction nozzle 221 can be selectively slid along the length direction or the width direction of the base 1 as needed, and the position of the nozzle can also be finely adjusted according to specific requirements to ensure that the suction nozzle 221 can accurately align with the component 200 to be picked up. In addition, the first elongated hole 211 and the second elongated hole 212 provide multiple mounting possibilities, making the layout of the suction nozzle 221 more flexible. The position of any suction nozzle 221 can be flexibly adjusted according to the shape, size and arrangement of different components 200 to be picked up to adapt to different production requirements. This adaptability enables the picking device 10 to have a wider application range, improves the utilization rate of the picking device 10, and saves costs. The design of the first elongated hole 211 and the second elongated hole 212 makes the installation process of any suction nozzle 221 simpler and faster. There is no need for complex fixing devices or tools, and any suction nozzle 221 can be simply slid into the corresponding elongated hole and fixed.

[0079] In some embodiments, multiple sliding structures are provided. The multiple sliding structures are arranged in one-to-one correspondence with the multiple suction nozzles 221. Each suction nozzle 221 is slidably mounted in the first elongated hole 211 or the second elongated hole 212 of the corresponding sliding structure. Thus, the sliding structure enables each suction nozzle 221 to freely slide in the corresponding first elongated hole 211 or second elongated hole 212 as needed, realizing the adjustment of the position of each suction nozzle 221 according to actual production requirements. This flexibility enables the picking device 10 to easily adapt to components 200 of different sizes, shapes and arrangements, improving the adaptability and application range of the picking device 10. By adjusting the position of each suction nozzle 221 in the first elongated hole 211 or the second elongated hole 212, an optimized layout between the suction nozzles 221 can be achieved, which helps to reduce the interference between the suction nozzles 221, improve the picking efficiency, and reduce the risk of failure of the picking device 10. The design of the sliding structure makes the installation of the suction nozzle 221 simple and fast. The operator only needs to align the suction nozzle 221 with the first elongated hole 211 or the second elongated hole 212 and slide it to the appropriate position to complete the installation. This installation method does not require complex fixing devices or tools, reducing the installation difficulty and cost. The sliding structure allows the operator to precisely adjust each suction nozzle 221 to ensure that it can accurately align with the position of the component 200 to be picked up. This precise adjustment helps to improve the picking accuracy and reduce the picking failure or damage to the component 200 to be picked up caused by position deviation.

[0080] Refer toFigure 2 and Figure 5 , in some embodiments, the mounting portion 21 includes two mounting seats 213 spaced along the second direction, and an adsorption portion 22 is mounted on each mounting seat 213. A clamping assembly 202 is disposed between the two mounting seats 213. In this way, the force on the component 200 to be picked up during the picking process is more dispersed, which helps to reduce the risk of damage or picking failure of the component 200 to be picked up caused by excessive force at a single point, and improves the stability and reliability of picking up the component 200 to be picked up. In addition, when the force applied by the clamping assembly 202 and the suction force of the two adsorption portions 22 act together on the component 200 to be picked up, the component 200 to be picked up is in force balance, ensuring that the component 200 to be picked up is less likely to shake or fall off during movement or transfer, thereby improving the reliability and safety of the entire picking device 10. The two mounting seats 213, as independent modules, can be easily installed, disassembled and replaced. This modular design simplifies the installation and maintenance process of the picking device 10, and reduces the maintenance cost and time.

[0081] It should be noted that the two mounting seats 213 can move synchronously, and the two mounting seats 213 can also move separately. Specifically, the movement of the two mounting seats 213 can be set as needed, and the present application does not limit this. In addition, the present application does not limit the shapes of the two mounting seats 213, and the specific shapes of the two mounting seats 213 can be set as needed.

[0082] Referring to Figure 1 , Figure 2 and Figure 5, in some embodiments, the mounting portion 21 further includes a connecting arm 215. The connecting arm 215 connects two mounting seats 213. The picking unit 2 further includes a second driving component 4. The second driving component 4 is mounted on the base 1. The driving end of the second driving component 4 has a moving stroke in the first direction. The driving end is drivingly connected to one of the two mounting seats 213. In this way, the connecting arm 215 connects the two mounting seats 213, making them physically associated. When the second driving component 4 drives one of the two mounting seats 213 to move in the first direction, due to the action of the connecting arm 215, the other of the two mounting seats 213 will also move accordingly, so that the other of the two mounting seats 213 will follow one of the two mounting seats 213 to move synchronously or approximately synchronously. This synchronism helps the two suction portions 22 to maintain a consistent attitude and position during the picking process, thereby improving the efficiency of collaborative work. By using one second driving component 4 to drive the two mounting seats 213 simultaneously, the number of driving sources is reduced. This not only simplifies the structure of the picking device 10, but also reduces energy consumption and cost. At the same time, it also reduces the synchronization control problems and failure risks that may be brought by multiple driving sources. As a connecting member between the two mounting seats 213, the connecting arm 215 not only transmits the driving force, but also enhances the connection strength between the two. This enhanced connection helps to improve the stability of the overall structure of the picking device 10.

[0083] It should be noted that the present application does not limit the shape of the connecting arm 215, and the specific shape of the connecting arm 215 can be set according to needs. In addition, there are various types of the second driving component 4. For example, the second driving component 4 may include a telescopic cylinder, a hydraulic cylinder, a linear motor, or an electric push rod. Specifically, in one embodiment, the second driving component 4 includes a telescopic cylinder. Since the thrust generated by the telescopic cylinder by compressing air can achieve precise control of the position of the first mounting seat 213. The telescopic cylinder has a fast response speed and can complete the driving action of the first mounting seat 213 in a short time, improving the production picking efficiency. The structure of the telescopic cylinder is relatively simple and has been optimized design, with high stability and reliability. During long-term operation, it can maintain stable performance output. By directly driving the first mounting seat 213 with the telescopic cylinder, the design of the transmission mechanism can be simplified, the number and complexity of transmission components can be reduced, thereby reducing the failure rate and maintenance cost. The driving method of the telescopic cylinder has a high energy efficiency ratio and can reduce energy consumption while ensuring the driving effect, which conforms to the environmental protection concept of energy conservation and emission reduction. The telescopic cylinder is easy to disassemble and replace. During maintenance and repair, the cylinder can be easily cleaned, inspected, and repaired. Of course, in other embodiments, the type of the second driving component 4 can be selected according to needs, and the present application does not limit this.

[0084] Continue to refer to Figure 4 and Figure 6, in one embodiment, at least two picking units are provided. The at least two picking units are arranged on the base 1 at intervals. In this way, by providing at least two picking units, simultaneous picking of at least two components 200 to be picked can be achieved, greatly improving the picking efficiency. Additionally, when it is necessary to pick a component 200 to be picked with a larger size, the at least two picking units can pick simultaneously, realizing the dispersion of the load of the component 200 to be picked onto different picking units, thereby reducing the load pressure on a single picking unit and improving the stability and reliability of picking. In some cases, even if a certain picking unit fails or malfunctions, other picking units can still operate normally, thus ensuring the continuity and stability of picking. The modular design of the picking unit makes maintenance and servicing work simpler and more convenient. When a certain picking unit fails, it can be repaired or replaced individually without affecting the normal operation of other picking units.

[0085] Referring to Figures 1 to 3 , in one embodiment, the second driving assembly 4 includes a telescopic cylinder, and the first driving assembly 5 includes a clamping cylinder 51. The telescopic cylinder is externally connected to a gas supply device through a first pipeline, and the clamping cylinder 51 is connected to a second pipeline through a pneumatic pipe adapter 9. The second pipeline is externally connected to a gas supply device. A vacuum gauge 101 is provided on the first pipeline, and a pressure conversion valve 102 is provided on the first pipeline and / or the second pipeline. In this way, it is detected by the vacuum gauge 101 whether the adsorbed product is stably adsorbed. The pressure conversion valve 102 provided on the first pipeline is used to adjust the air pressure in the first pipeline and can convert the positive and negative air pressures in the first pipeline. The pressure conversion valve 102 provided on the second pipeline is used to adjust the air pressure in the second pipeline and can convert the positive and negative air pressures in the second pipeline. The second pipeline synchronously diverts the air pressure through the pneumatic pipe adapter 9, enabling the air pressure to enter different chambers of the clamping cylinder 51 respectively, and enabling the two piston rods 511 of the clamping cylinder 51 to be driven respectively.

[0086] According to a second aspect of the present disclosure, a testing device is provided. The testing device is used to perform performance testing on a component 200 to be picked. The testing device includes the above-mentioned picking device 10 and a manipulator. The manipulator is connected to the base 1, and the manipulator is used to move the picking device to a material taking position or a material placing position.

[0087] In the test device according to the embodiments of the present application, by providing a manipulator connected to the base 1, the manipulator can move the picking device 10 to the material picking position or the material placing position according to actual needs, and the picking device 10 can stably and reliably pick up or place the component 200 to be picked at the material picking position or the material placing position, which can improve the accuracy of testing the component 200 to be picked to a certain extent. In addition, the provision of the manipulator reduces the need for manual intervention, thereby shortening the test cycle and improving the overall efficiency of the production line. At the same time, since the manipulator can work continuously and stably without being affected by factors such as fatigue and emotions, it can maintain a high working efficiency and stability.

[0088] Referring to Figures 1 to 3 , in some embodiments, the test device further includes an image acquisition component 20. The image acquisition component 20 is installed on the base 1 and is used to acquire the position information of the component 200 to be picked. At least one of the adsorption component 201 and the manipulator and the image acquisition component 20 are used to be electrically connected to the controller. Thus, the image acquisition component 20 can capture the image of the component 200 to be picked in real time and extract its position information through image processing technology. This enables the controller to accurately understand the current position of the component 200 to be picked, so as to guide one of the manipulator and the adsorption component 201 to perform position adjustment to achieve accurate picking. After receiving the position information transmitted by the image acquisition component 20, the controller can automatically calculate and decide the movement path of the manipulator and / or the operation mode of the adsorption component 201 to realize an intelligent picking operation. The automated image acquisition and picking operation reduces the need for manual operation, reduces the dependence on skilled workers and labor costs, improves the picking accuracy and efficiency, and can reduce the downtime and resource waste caused by picking failures.

[0089] It should be noted that the image acquisition component 20 can work under different lighting conditions, background noises and occlusions, and has strong environmental adaptability. This enables the picking device 10 to operate stably in various complex production environments and improves the reliability and stability of the production line. The image acquisition component 20 has a fast response speed and high processing efficiency, and can capture and process the image information of the component 200 to be picked in real time. This enables the picking device 10 to quickly complete the picking task and improves the overall production efficiency of the production line.

[0090] There are various types of the image acquisition component 20. For example, the image acquisition component 20 can include a vision camera, a camera or an image sensor, etc. Specifically, the type of the image acquisition component 20 can be set according to needs, and the present application does not limit this.

[0091] In one embodiment, the image acquisition component 20 is located between the two picking units 2. In this way, it can be ensured that the component 200 to be picked is always within the optimal viewing angle and focal length range of the image acquisition component 20. This layout helps to reduce recognition errors caused by changes in angle, distance or light, thereby improving the accuracy and reliability of image recognition. Once the image acquisition component 20 recognizes the component 200 to be picked, the two picking units 2 can quickly and accurately move to the target position for picking. Since the image acquisition component 20 is located in the middle, the movement path of the picking unit 2 may be more direct and efficient, reducing unnecessary movement and waiting time, thus improving the overall picking efficiency. Because the image acquisition component 20 is located in the middle, it can more easily adjust the focal length, viewing angle or light conditions to adapt to the characteristics of different objects, while the picking unit 2 can flexibly adjust its picking strategy according to the information provided by the image acquisition component 20. By placing the image acquisition component 20 between the two picking units 2, the test device has a compact structure and can make more effective use of space.

[0092] Referring to Figures 1 to 3 , in some embodiments, the test device further includes a distance sensor 30. The distance sensor 30 is installed on the base 1. The distance sensor 30 is used to detect the distance between the component 200 to be picked and the adsorption component 201 or the clamping component 202. Among them, at least one of the adsorption component 201 and the manipulator and the distance sensor 30 are electrically connected to the controller. In this way, the distance sensor 30 can measure the distance between the component 200 to be picked and the adsorption component 201 or the clamping component 202 in real time, ensuring that no collision or misoperation occurs during the picking process. Through distance monitoring, when it is detected that the distance is too close or abnormal, the controller can immediately issue an instruction to stop the movement of the manipulator and / or the adsorption component 201, avoiding damage to the component 200 to be picked or the test device and improving the safety of the operation. According to the feedback of the distance sensor 30, the controller can dynamically adjust the movement trajectory and speed of the manipulator and / or the adsorption component 201 to adapt to components 200 to be picked with different sizes, shapes and positions, improving the flexibility and adaptability of picking. Electrically connecting the distance sensor 30 to the controller can achieve integrated control of the entire picking process and improve the intelligence and automation level of the test device.

[0093] Referring to Figures 1 to 3, in some embodiments, the testing device further includes an offset sensor for detecting the position deviation of the component 200 to be picked up. Both the offset sensor and the manipulator are electrically connected to the controller. The offset sensor can monitor in real time the deviation between the actual position and the theoretical or expected position of the component 200 to be picked up. This real-time feedback enables the controller to immediately identify and respond to the position deviation, thereby guiding the manipulator to make adjustments so that the picking device 10 can pick up precisely. The controller can automatically calculate and adjust the motion trajectory of the manipulator according to the data of the offset sensor to compensate for the position deviation of the component 200 to be picked up. This automatic compensation mechanism improves the intelligence level of the system and reduces the need for manual intervention. Since the offset sensor can detect in real time and control the activities of the manipulator through the controller to correct the position deviation, the reject rate caused by inaccurate picking can be significantly reduced, and the product quality can be improved.

[0094] The following takes the testing of the component 200 to be picked up by the testing device as an example for illustration. Two picking devices are provided, and the two picking devices include a loading picking device and an unloading picking device:

[0095] After the controller of the testing device obtains the feeding signal, the controller controls the manipulator to move to the picking position, collects the position information of the component 200 to be picked up through the image acquisition component 20, and / or detects the distance between the component 200 to be picked up and the adsorption component 201 or the clamping component 202 through the distance sensor 30, and / or detects the position deviation of the component 200 to be picked up through the offset sensor, and feeds back the position information and / or the distance information and / or the position deviation to the controller. The controller controls the multiple suction nozzles 221 of the feeding picking device to accurately move to the appropriate position and evacuate to adsorb the component 200 to be picked up from the picking position. When the adsorption component 201 moves to the preset position, the first clamping part 23 and the second clamping part 24 of the clamping component 202 of the feeding picking device approach each other to clamp the component 200 to be picked up adsorbed by the multiple suction nozzles 221. The controller controls the manipulator to move to the testing and material changing position, collects the position information of the component 200 to be picked up through the image acquisition component 20, and / or detects the distance between the component 200 to be picked up and the adsorption component 201 or the clamping component 202 through the distance sensor 30, and / or detects the position deviation of the component 200 to be picked up through the offset sensor, and feeds back the position information and / or the distance information and / or the position deviation to the controller. The controller controls the multiple suction nozzles 221 of the discharging picking device to move to the appropriate position and evacuate to adsorb the component 200 to be picked up from the testing and material changing position. When the adsorption component 201 moves to the preset position, the first clamping part 23 and the second clamping part 24 of the clamping component 202 of the discharging picking device approach each other to clamp the component 200 to be picked up adsorbed by the multiple suction nozzles 221. The controller controls the manipulator to move to the discharging position. The controller controls the multiple suction nozzles 221 of the feeding picking device to stop evacuating and makes the first clamping part 23 and the second clamping part 24 move away from each other to release the component 200 to be picked up to achieve discharging. The controller controls the manipulator to move to the detection position, detects whether the component 200 to be picked up is placed out of position, and performs a performance test on the component 200 to be picked up. After the test is completed, the controller controls the manipulator to move to the discharging position. The controller controls the multiple suction nozzles 221 of the discharging picking device to stop evacuating and makes the first clamping part 23 and the second clamping part 24 move away from each other to release the component 200 to be picked up to achieve discharging. The controller controls the manipulator to move to the safe position to wait for the feeding signal. The above is the entire automated cyclic working process.
