Abstract
Description
Technical Field
[0001] This application relates to the field of battery cell processing production line technology, and in particular to a transportation device. Background Technology
[0002] Currently, battery cell processing production lines typically have multiple workstations. Materials need to be moved sequentially to different workstations via conveying equipment. When a material arrives at a designated workstation, the corresponding equipment at that workstation performs actions such as loading, unloading, and processing. The conveying equipment usually includes a turntable device, which can move the material along a circumferential path by rotating, so that the material passes through the designated workstation.
[0003] In related technologies, the turntable device includes a base, a rotating platform, a drive motor, and a photoelectric module. The drive motor is mounted on the base and connected to the rotating platform, while the photoelectric module is positioned at a designated workstation. In practical applications, materials are carried on the rotating platform, and the drive motor rotates the platform to move the materials. When the photoelectric module senses the material, it determines that the material has moved to the corresponding workstation. When the photoelectric module does not sense the material, it determines that the material has not moved to the corresponding workstation. However, the above technology suffers from technical problems such as complex mechanisms and low space utilization. Utility Model Content
[0004] In view of the above, it is necessary to provide a transportation device that has the technical effect of simplifying hardware structure and improving space utilization.
[0005] This application provides a transport device, including: a rotating base; two or more adsorption platforms disposed on the rotating base, the adsorption platforms being used to carry materials; a drive assembly connected to the rotating base, the drive assembly being used to drive the rotating base to rotate, thereby moving any adsorption platform sequentially to multiple transport stations; two or more pneumatic assemblies, each transport station being provided with one or more pneumatic assemblies; an air slip ring, the stator of the air slip ring being connected to the pneumatic assemblies, the mover of the air slip ring being able to connect with the adsorption platform that has moved to the transport station corresponding to the pneumatic assemblies, so that an airflow passage is formed between the pneumatic assemblies and the adsorption platforms; the pneumatic assemblies are configured to put the airflow passage into a vacuum state or a vacuum breaking state when the rotating base rotates to a specified angle.
[0006] In some embodiments, the pneumatic assembly includes: a vacuum generator; a negative pressure switch; a first negative pressure line connected to the vacuum generator and a slip ring; a second negative pressure line connected to the vacuum generator and the negative pressure switch; and a third negative pressure line connected to the negative pressure switch and a gas source; wherein the negative pressure switch is configured to switch the on / off state between the first negative pressure line and the second negative pressure line when the rotating seat rotates to a specified angle.
[0007] In some embodiments, the pneumatic assembly further includes: a vacuum breaking switch; a first vacuum breaking line connected to the vacuum breaking switch and a gas slip ring; and a second vacuum breaking line connected to the vacuum breaking switch and a gas source; wherein the vacuum breaking switch is configured to switch the on / off state between the first vacuum breaking line and the second vacuum breaking line when the rotating seat rotates to a specified angle.
[0008] In some embodiments, the negative pressure switch and the vacuum breaking switch are integrated into a dual-electro-controlled solenoid valve, the second negative pressure line and the third negative pressure line are respectively connected to the first port of the dual-electro-controlled solenoid valve, and the first vacuum breaking line and the second vacuum breaking line are respectively connected to the second port of the dual-electro-controlled solenoid valve.
[0009] In some embodiments, the first vacuum breaking line is connected to the first negative pressure line, and the connection point between the first vacuum breaking line and the first negative pressure line is located between the air slip ring and the vacuum generator.
[0010] In some embodiments, the pneumatic assembly further includes a pneumatic detection element connected to a first negative pressure line.
[0011] In some embodiments, the number of adsorption platforms is greater than or equal to 2, and the multiple adsorption platforms are distributed at intervals around the center of the rotating seat; when the rotating seat rotates to a specified angle, the multiple adsorption platforms move to multiple transport stations respectively.
[0012] In some embodiments, the number of pneumatic components is greater than or equal to 2, each pneumatic component corresponds to a transport station, and multiple pneumatic components are connected to air slip rings.
[0013] In some embodiments, the multiple transport stations include a material unloading station and a processing station, wherein the adsorption table moving to the material unloading station is used to receive the material to be processed, or to allow other devices to remove the processed material; the adsorption table moving to the processing station is used to carry the material to be processed.
[0014] In some embodiments, there are multiple feeding stations, one of which is defined as the first feeding station and the other as the second feeding station. When the adsorption table feeds material alone, the first feeding station is used to receive the material to be processed, and the second feeding station is used to allow other external devices to remove the processed material. When multiple adsorption tables feed multiple materials together, both the first feeding station and the second feeding station are used to receive the material to be processed and also to allow other external devices to remove the processed material.
[0015] The transport device provided in this application allows for direct determination of whether each adsorption platform has reached its corresponding transport station by utilizing the rotation angle of the rotating base, thereby triggering the adsorption or release of materials. It eliminates the need for multiple additional photoelectric modules to detect the position of the adsorption platforms and trigger the pneumatic components, thus eliminating the need for space for photoelectric module installation or light transmission. This results in a simpler transport device structure, higher space utilization, and a smaller equipment size. Attached Figure Description

[0039] In the description of the embodiments of this application, when an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an element centrally located simultaneously. When an element is considered to be "set" on another element, it can be directly set on the other element or there may be an element centrally located simultaneously. In this application, unless otherwise expressly specified and limited, the terms "installed," "connected," "attached," "fixed," etc., should be interpreted broadly. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two elements. For those skilled in the art, the specific meaning of the above terms in this application can be understood according to the specific circumstances. The directional descriptions in this embodiment, such as "up," "down," "top," "bottom," etc., are all based on the direction of the product in the actual use scenario.
[0040] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.
[0041] In related technologies, the turntable device includes a base, a rotating platform, a drive motor, and a photoelectric module. The drive motor is mounted on the base and connected to the rotating platform, while the photoelectric module is positioned corresponding to a designated workstation. In practical applications, materials are carried on the rotating platform, and the drive motor rotates the platform to move the materials. When the photoelectric module senses the material, it determines that the material has moved to the corresponding workstation. When the photoelectric module does not sense the material, it determines that the material has not moved to the corresponding workstation.
[0042] However, the turntable device not only needs to leave enough space for the installation of each optoelectronic module, but also needs to reserve space for the light propagation of the optical path of the optoelectronic module, resulting in a complex mechanism and a large space occupied by the entire device.
[0043] Therefore, this application provides a transportation device.
[0044] Figure 1 A schematic diagram of the processing equipment provided in this application. Figure 2 A schematic diagram of the transportation device provided in this application.
[0045] like Figure 1 and Figure 2 As shown, the conveying device 100 can be applied to the processing equipment 1000, which includes the conveying device 100, the processing device 200, and the transfer device 300. The conveying device 100 is a rotary table type device capable of carrying and driving the material 400 in a circular motion. The conveying device 100 is positioned between the processing device 200 and the transfer device 300, and both the processing device 200 and the transfer device 300 pass through the movement path of the material 400. When the material 400 moves to the position corresponding to the processing device 200 under the drive of the conveying device 100, the processing device 200 can process the material 400 (i.e., complete the processing action). When the material 400 moves to the position corresponding to the transfer device 300 under the drive of the conveying device 100, the transfer device 300 can place the material 400 to be processed onto the conveying device 100 (i.e., complete the loading action) or remove the processed material 400 from the conveying device 100 (i.e., complete the unloading action). Thus, the transport device 100, processing device 200 and transfer device 300 work together to realize the automatic processing and automatic loading and unloading of materials 400.
[0046] In the example of this application, material 400 can be a sheet material such as silicon wafer, and the sheet material can be fed into the transport device 100 in the form of half a sheet, a whole sheet, or multiple sheets (such as in pairs).
[0047] In the examples of this application, the processing device 200 can be a laser device, and there may be one or more processing devices 200. When there are multiple processing devices 200, the multiple processing devices 200 can be configured to sequentially perform laser processing on the same material 400, or they can be configured to sequentially and simultaneously perform laser processing on different materials 400.
[0048] In the example of this application, the transfer device 300 can be an adsorption-type gripping device, that is, it grips the material 400 by adsorption and moves the material 400. The transfer device 300 can realize loading and unloading actions. The transfer device 300 can be a standalone device, which realizes the loading and unloading actions on its own; the transfer device 300 can also be a combination of multiple devices. For example, the transfer device 300 includes a loading component and an unloading component. The loading component is correspondingly provided with a first transfer station 301, where the loading component can realize the loading action, and the unloading component is correspondingly provided with a second transfer station 302, where the unloading component can realize the unloading action. Specifically, the transfer device 300 also includes a camera component, which can take pictures of the material 400 during the loading action to obtain image information of the material 400. The image information can be used to identify and mark the material 400 for systematic management of the material 400.
[0049] Figure 3 A schematic diagram of the transportation device provided in this application.
[0050] Please refer to the following: Figure 3 In this embodiment, the transport device 100 includes a rotating base 10, two or more adsorption platforms 20, a drive assembly 30, two or more pneumatic assemblies 40, and a slip ring 50. The two or more adsorption platforms 20 are all disposed on the rotating base 10, and the adsorption platforms 20 are used to carry the material 400. The drive assembly 30 is connected to the rotating base 10. The drive assembly 30 is used to drive the rotating base 10 to rotate, thereby moving any one of the adsorption platforms 20 sequentially to multiple transport stations 11, which are circumferentially spaced around the rotation axis of the rotating base 10.
[0051] The transport station 11 refers to the area reached by the adsorption table 20 when it moves to a certain angle. The position of the transport station 11 is preset and fixed relative to the processing device 200 and the transfer device 300. During the rotation of the rotating seat 10, the rotating seat 10 can drive each adsorption table 20 to move synchronously in a circular motion, so that each adsorption table 20 can pass through each transport station 11 in sequence. Two or more pneumatic components 40 are provided, and each transport station 11 is provided with one or more pneumatic components 40, that is, there is a corresponding relationship between each transport station 11 and at least one pneumatic component 40. In this embodiment, each pneumatic component 40 is provided corresponding to one transport station 11.
[0052] The air slip ring 50 has a stator 52 and a mover 51. The stator 52 of the air slip ring 50 is connected to the pneumatic assembly 40, and the mover 51 of the air slip ring 50 can be connected to the adsorption stage 20 that moves to the corresponding transport station 11 of the pneumatic assembly 40, so that an airflow passage is formed between the pneumatic assembly 40 and the adsorption stage 20. The pneumatic assembly 40 is configured to put the airflow passage into a vacuum state or a vacuum breaking state when the rotating seat 10 rotates to a specified angle.
[0053] It is understood that when the drive component 30 drives the rotating seat 10 to rotate to a specified angle, each adsorption table 20 moves to each transport station 11. The air slip ring 50 forms an airflow passage between the air pressure component 40 corresponding to each transport station 11 and the adsorption table 20 arriving at each transport station 11. Each air pressure component 40 puts the corresponding airflow passage into a vacuum state or a vacuum breaking state so that the corresponding adsorption table 20 adsorbs or releases the material 400.
[0054] By utilizing the correspondence between multiple transport stations 11 and multiple pneumatic components 40, as well as the rotation angle of the rotating seat 10, it is possible to directly determine whether the position of each adsorption platform 20 has reached the corresponding transport station 11, and trigger the adsorption or release of material 400. Thus, the transport device 100 does not require additional photoelectric modules to detect the position of the adsorption platform 20 and trigger the pneumatic components 40 to operate. Consequently, no space needs to be reserved for the installation of photoelectric modules or for the propagation of light from photoelectric modules, making the structure of the transport device 100 simpler, with higher space utilization and a smaller equipment size.
[0055] In some embodiments, the upper surface of the adsorption stage 20 is provided with a plurality of adsorption holes, and the side surface of the adsorption stage 20 is provided with a plurality of connecting holes. The connecting holes are connected to the mover 51 of the air slip ring 50 through pipes, so that an airflow passage can be formed between the connecting holes and the air pressure assembly 40. The adsorption stage 20 is provided with a connecting air passage, and the plurality of adsorption holes and the plurality of connecting holes are connected through the connecting air passage.
[0056] When material 400 is placed on adsorption stage 20, material 400 covers at least one adsorption hole. If the pneumatic component 40 puts the airflow passage into a vacuum state, the adsorption stage 20 forms a negative pressure at the adsorption hole to adsorb and fix material 400, preventing material 400 from falling off the adsorption stage 20. If the pneumatic component 40 puts the airflow passage into a vacuum state, material 400 is allowed to fall off the adsorption stage 20.
[0057] Specifically, the shape and size of the adsorption stage 20 can be configured according to the material 400. In the example of this application, the adsorption stage 20 is generally rectangular, and the area of the adsorption stage 20 is configured to be greater than or equal to the area of a single sheet material.
[0058] The adsorption stage 20 provided in this application has at least the following two support methods.
[0059] Figure 4 This is a schematic diagram showing the state in which the adsorption stage provided in this application supports the entire piece. Figure 5 This is a schematic diagram showing the state of the adsorption stage supporting the half-piece provided in this application.
[0060] Please refer to the following: Figure 4 and Figure 5 In the first bearing method, each adsorption stage 20 bears a whole sheet of material. In the second bearing method, each adsorption stage 20 bears multiple half sheets of material. This allows each adsorption stage 20 to support various bearing scenarios to meet different process requirements.
[0061] Specifically, the number of adsorption platforms 20 can be configured according to the transportation method of the material 400. In the example of this application, the number of adsorption platforms 20 is 4, and the four adsorption platforms 20 are distributed in a circular interval around the rotation axis of the rotating seat 10.
[0062] The transport device 100 provided in this application has at least two of the following modes of transport.
[0063] Figure 6 A schematic diagram of the state of the transportation device provided in this application when a single material is transported independently. Figure 7 A schematic diagram of the state of the transport device provided in this application when multiple materials are transported in pairs. Figure 6 , Figure 7 The dashed arrows in the diagram indicate the loading and unloading actions of materials.
[0064] Please refer to the following: Figure 6 and Figure 7 In the first transportation method, a single material 400 is independently fed. Each adsorption table 20 performs a single process, with each adsorption table 20 carrying the material 400 and driving the material 400 to complete the feeding, processing, and unloading actions in sequence.
[0065] In the second transportation method, multiple materials 400 are transported in pairs. Multiple adsorption tables 20 jointly feed multiple materials 400, that is, multiple adsorption tables 20 jointly perform one process, and drive multiple materials 400 to complete the feeding action, processing action and unloading action in sequence.
[0066] The phrase "multiple adsorption platforms 20 jointly feed multiple materials 400" means that multiple materials 400 constitute a group of materials 400, and all sheet materials in this group of materials 400 simultaneously complete the feeding, processing and unloading actions.
[0067] For example, the materials 400 supported on the two adsorption platforms 20 form a group. The two adsorption platforms 20 jointly feed the pairs of materials 400, and drive the pairs of materials 400 to simultaneously and sequentially complete the feeding, processing, and unloading actions. In this way, the transport device 100 can support two transport modes: independent transport of a single material 400 and transport of multiple materials 400 in pairs, to meet different process requirements.
[0068] In some embodiments, two adjacent adsorption platforms 20 are arranged side by side. In the example of this application, the four adsorption platforms 20 are distributed in a matrix so that two adjacent adsorption platforms 20 are arranged side by side along a straight line. In this way, when multiple adsorption platforms 20 jointly carry multiple materials 400, multiple sheet materials belonging to the same multiple materials 400 can be directly placed on the side by side adsorption platforms 20 at the same time, which facilitates the transfer of materials 400.
[0069] In some embodiments, the plurality of transport stations 11 include a material unloading station and a processing station, wherein the suction table 20 moved to the material unloading station is used to receive the material 400 to be processed, or to allow other devices to remove the processed material 400. The suction table 20 moved to the processing station is used to carry the material 400 to be processed.
[0070] Specifically, the location of the unloading station corresponds to the setting of the transfer device 300. When the adsorption table 20 carrying the material 400 moves to the unloading station, the transfer device 300 can process the material 400 located in the processing station.
[0071] The processing station is positioned corresponding to the processing device 200. When the adsorption table 20 carrying the material 400 moves to the processing station, the processing device 200 can process the material 400 located in the processing station.
[0072] In the example of this application, multiple unloading stations are located between the first transfer station 301 and the second transfer station 302, so that the first transfer station 301, the multiple unloading stations, and the second transfer station 302 are distributed at intervals along a straight line. In this way, the requirements of the processing technology can be guaranteed, and the equipment can be reasonably laid out to facilitate the installation of other auxiliary equipment such as a wafer-picking robot.
[0073] Specifically, the number of transport stations 11 can be configured according to the transport method of material 400. In the example of this application, the distribution of each transport station 11 corresponds to the distribution of each adsorption table 20. The number of transport stations 11 is 4, and the four transport stations 11 are distributed in a circular interval around the rotation axis of the rotating seat 10, with a rotation angle difference of 90° between two adjacent transport stations 11.
[0074] Correspondingly, there are 4 pneumatic components 40, and the four pneumatic components 40 are used to form airflow passages with the adsorption table 20 that moves to the corresponding transport station 11.
[0075] In the example of this application, there are two processing stations, one of which is defined as the first processing station 11B, and the other as the second processing station 11C. There are also two unloading stations, one of which is defined as the first unloading station 11A, and the other as the second unloading station 11D. The first unloading station 11A, the first processing station 11B, the second processing station 11C, and the second unloading station 11D are distributed sequentially.
[0076] The first transfer station 301 is located on the side of the first unloading station 11A away from the second unloading station 11D, and the second transfer station 302 is located on the side of the second unloading station 11D away from the first unloading station 11A. The first transfer station 301, the first unloading station 11A, the second unloading station 11D, and the second transfer station 302 are distributed at intervals along a straight line.
[0077] The four sets of pneumatic components 40 are defined as pneumatic component 40A, pneumatic component 40B, pneumatic component 40C and pneumatic component 40D.
[0078] Four adsorption stages 20 are defined as adsorption stage 20A, adsorption stage 20B, adsorption stage 20C, and adsorption stage 20D. The rotating seat 10 is defined to be able to rotate sequentially to the first angle, the second angle, the third angle, and the fourth angle. The angle of rotation of the rotating seat 10 each time is 90°×X, where X is a positive integer.
[0079] When the rotating seat 10 rotates to the first angle (e.g., 0°), the adsorption table 20A is located at the first unloading station 11A, the adsorption table 20B is located at the first processing station 11B, the adsorption table 20C is located at the second processing station 11C, and the adsorption table 20D is located at the second unloading station 11D. An airflow passage is formed between the pneumatic assembly 40A and the adsorption table 20A, between the pneumatic assembly 40B and the adsorption table 20B, between the pneumatic assembly 40C and the adsorption table 20C, and between the pneumatic assembly 40D and the adsorption table 20D.
[0080] When the rotating seat 10 rotates to the second angle (e.g., 90°), the adsorption table 20D is located at the first unloading station 11A, the adsorption table 20A is located at the first processing station 11B, the adsorption table 20B is located at the second processing station 11C, and the adsorption table 20C is located at the second unloading station 11D. An airflow passage is formed between the pneumatic assembly 40A and the adsorption table 20D, between the pneumatic assembly 40B and the adsorption table 20A, between the pneumatic assembly 40C and the adsorption table 20B, and between the pneumatic assembly 40D and the adsorption table 20C.
[0081] When the rotating seat 10 rotates to the third angle (e.g., 180°), the adsorption table 20C is located at the first unloading station 11A, the adsorption table 20D is located at the first processing station 11B, the adsorption table 20A is located at the second processing station 11C, and the adsorption table 20B is located at the second unloading station 11D. An airflow passage is formed between the pneumatic assembly 40A and the adsorption table 20C, between the pneumatic assembly 40B and the adsorption table 20D, between the pneumatic assembly 40C and the adsorption table 20A, and between the pneumatic assembly 40D and the adsorption table 20B.
[0082] When the rotating seat 10 rotates to the fourth angle (e.g., 270°), the adsorption table 20B is located at the first unloading station 11A, the adsorption table 20C is located at the first processing station 11B, the adsorption table 20D is located at the second processing station 11C, and the adsorption table 20A is located at the second unloading station 11D. An airflow passage is formed between the pneumatic assembly 40A and the adsorption table 20B, between the pneumatic assembly 40B and the adsorption table 20C, between the pneumatic assembly 40C and the adsorption table 20D, and between the pneumatic assembly 40D and the adsorption table 20A.
[0083] In the example of this application, the transport device 100 can support two transport modes: independent transport of a single material 400 and transport of multiple materials 400 in pairs, which correspond to two cases: the adsorption table 20 feeding material 400 alone and multiple adsorption tables 20 feeding multiple materials 400 together.
[0084] Figure 8A schematic diagram illustrating the operation of the transport device provided in this application during the independent transport of a single material.
[0085] Please refer to the following: Figure 8 In the case of independent transportation of a single material 400, each adsorption station 20 independently carries the material 400. The first unloading station 11A is used to receive the material 400 to be processed, and the second unloading station 11D is used for external unloading devices to remove the processed material 400. The operation mode of the transportation device 100 can be as follows:
[0086] The rotating seat 10 rotates by 90° each time.
[0087] When the rotating seat 10 rotates to the first angle, the transfer device 300 is allowed to place the material 400 to be processed onto the adsorption table 20A. The pneumatic component 40A evacuates the corresponding airflow passage to adsorb and fix the material 400 onto the adsorption table 20A; the pneumatic component 40B evacuates the corresponding airflow passage to hold the material 400 fixed onto the adsorption table 20B; the pneumatic component 40C evacuates the corresponding airflow passage to hold the material 400 fixed onto the adsorption table 20C; and the pneumatic component 40D de-vacuums the corresponding airflow passage to allow the transfer device 300 to remove the processed material 400 from the adsorption table 20D. After all the corresponding actions at each transport station 11 are completed, the rotating seat 10 is allowed to rotate to the second angle.
[0088] When the rotating seat 10 rotates to the second angle, the transfer device 300 is allowed to place the material 400 to be processed onto the adsorption table 20D. The pneumatic component 40A evacuates the corresponding airflow passage to adsorb and fix the material 400 onto the adsorption table 20D; the pneumatic component 40B evacuates the corresponding airflow passage to keep the material 400 fixed onto the adsorption table 20A; the pneumatic component 40C evacuates the corresponding airflow passage to keep the material 400 fixed onto the adsorption table 20B; and the pneumatic component 40D de-vacuums the corresponding airflow passage to allow the transfer device 300 to remove the processed material 400 from the adsorption table 20C. After all the corresponding actions at each transport station 11 are completed, the rotating seat 10 is allowed to rotate to the third angle.
[0089] When the rotating seat 10 rotates to the third angle, the transfer device 300 is allowed to place the material 400 to be processed onto the adsorption table 20C. The pneumatic component 40A evacuates the corresponding airflow passage to adsorb and fix the material 400 onto the adsorption table 20C; the pneumatic component 40B evacuates the corresponding airflow passage to hold the material 400 fixed onto the adsorption table 20D; the pneumatic component 40C evacuates the corresponding airflow passage to hold the material 400 fixed onto the adsorption table 20A; and the pneumatic component 40D de-vacuums the corresponding airflow passage to allow the transfer device 300 to remove the processed material 400 from the adsorption table 20B. After all the corresponding actions at each transport station 11 are completed, the rotating seat 10 is allowed to rotate to the fourth angle.
[0090] When the rotating seat 10 rotates to the fourth angle, the transfer device 300 is allowed to place the material 400 to be processed onto the adsorption table 20B. The pneumatic component 40A evacuates the corresponding airflow passage to adsorb and fix the material 400 onto the adsorption table 20B; the pneumatic component 40B evacuates the corresponding airflow passage to hold the material 400 fixed onto the adsorption table 20C; the pneumatic component 40C evacuates the corresponding airflow passage to hold the material 400 fixed onto the adsorption table 20D; the pneumatic component 40D de-vacuums the corresponding airflow passage to allow the transfer device 300 to remove the processed material 400 from the adsorption table 20A. After all the corresponding actions at each transport station 11 are completed, the rotating seat 10 is allowed to rotate to the first angle.
[0091] In this way, each adsorption platform 20 can independently realize the transportation of a single material 400, and enable each material 400 to complete the loading action, primary processing action, secondary processing action and unloading action in sequence.
[0092] Figure 9 A schematic diagram illustrating the operation of the transport device provided in this application when multiple materials are transported in pairs.
[0093] Please refer to the following: Figure 9 When multiple materials 400 are transported simultaneously, multiple adsorption tables 20 jointly feed multiple materials 400. The first discharge station 11A and the second discharge station 11D are both used to receive materials 400 to be processed, and also for external unloading devices to remove processed materials 400. The transport device 100 can operate as follows:
[0094] The rotating seat 10 rotates 180° each time.
[0095] When the rotating seat 10 rotates to the first angle, if there are no materials 400 to be processed placed on the adsorption stages 20A and 20D, the transfer device 300 is allowed to place multiple materials 400 to be processed on the adsorption stages 20A and 20D respectively. The pneumatic components 40A and 40D respectively put the corresponding airflow passages into a vacuum state to adsorb and fix the materials 400 on the adsorption stages 20A and 20D.
[0096] When processed materials 400 are placed on adsorption platforms 20A and 20D, the pneumatic components 40A and 40D respectively put the corresponding airflow passages into a vacuum state, so as to allow the transfer device 300 to remove the processed materials 400 from the adsorption platforms 20A and 20D respectively.
[0097] Simultaneously, pneumatic components 40B and 40C respectively evacuate the corresponding airflow passages, holding the multiple materials 400 fixed on the adsorption stages 20B and 20C, allowing the processing device 200 to process the multiple materials 400 on the adsorption stages 20B and 20C. After all the corresponding actions at each transport station 11 are completed, the rotating seat 10 is allowed to rotate to the third angle.
[0098] When the rotating seat 10 rotates to the third angle, if there are no materials 400 to be processed placed on the adsorption platforms 20B and 20C, the transfer device 300 is allowed to place multiple materials 400 to be processed on the adsorption platforms 20B and 20C respectively. The pneumatic components 40A and 40D respectively put the corresponding airflow passages into a vacuum state to adsorb and fix the materials 400 on the adsorption platforms 20B and 20C.
[0099] When processed materials 400 are placed on adsorption platforms 20B and 20C, pneumatic components 40A and 40D respectively put the corresponding airflow passages into a vacuum state to allow the transfer device 300 to remove the processed materials 400 from adsorption platforms 20B and 20C respectively.
[0100] Simultaneously, pneumatic components 40B and 40C respectively evacuate the corresponding airflow passages, holding the multiple materials 400 fixed on the adsorption stages 20A and 20D, allowing the processing device 200 to process the multiple materials 400 on the adsorption stages 20A and 20D. After all the corresponding actions at each transport station 11 are completed, the rotating seat 10 is allowed to rotate to the first angle.
[0101] In this way, each adsorption platform 20 is grouped into multiple groups, and multiple groups of adsorption platforms 20 can respectively realize the transportation of multiple materials 400, and enable multiple materials 400 to complete the loading, processing and unloading actions in sequence.
[0102] like Figure 2 As shown, in some embodiments, the air slip ring 50 adopts a cylindrical hollow design, supporting 360° unrestricted rotation. The mover 51 and stator 52 of the air slip ring 50 are distributed vertically, wherein the mover 51 is fixedly connected to the rotating base 10 and rotates synchronously with the rotating base 10. The stator 52 is fixed to a fixed object, which can be a device base. The mover 51 and stator 52 are rotatably connected, and the rotation axis of both coincides with the rotation axis of the rotating base 10.
[0103] Multiple air passages are formed between the mover 51 and the stator 52, each corresponding to a different transport station 11. The mover 51 has multiple first air vents on its periphery, each connected to one of the multiple air passages, and each of the multiple first air passages is connected to one of the multiple adsorption stages 20. The stator 52 has multiple second air vents on its periphery, each connected to one of the multiple air passages, and each of the multiple second air passages is connected to one of the multiple sets of pneumatic assemblies 40.
[0104] In the example of this application, the number of air passages is 4. The periphery of the mover 51 is provided with four first air ports, which are respectively connected to the connecting holes of the four adsorption stages 20 through pipelines. The periphery of the stator 52 is provided with four second air ports, which are respectively connected to four sets of air pressure components 40 through pipelines.
[0105] It is worth noting that the number of transport stations 11 in this embodiment is 4 as an example. In other embodiments, the number of transport stations can be greater than or equal to 4. The number of adsorption stages 20, the number of pneumatic components 40, and the number of air passages in the air slip ring 50 can all be adjusted adaptively. This application does not impose any restrictions on this.
[0106] like Figure 2 As shown, in some embodiments, the drive assembly 30 employs a direct drive motor (also known as a DD motor), the output of which is connected to the rotating base 10 to drive the rotating base 10 to rotate. In the example of this application, by obtaining the rotation angle of the output of the direct drive motor, the rotation angle of the rotating base 10 can be directly determined, thereby determining whether the rotating base 10 has rotated to the specified angle.
[0107] It is worth noting that in this embodiment, a direct drive motor is used as the drive component 30. In other embodiments, a servo motor, a stepper motor, or the like can also be used as the drive component 30, as long as it can drive the rotation of the rotating seat 10 and know the rotation angle of the rotating seat 10. This application does not impose any restrictions on this.
[0108] Figure 10 This is a schematic diagram of the structure of the pneumatic assembly provided in this application.
[0109] Please refer to the following: Figure 3 and Figure 10 In some embodiments, each pneumatic assembly 40 includes a vacuum generator 41, a negative pressure switch 471, a first negative pressure line 42, a second negative pressure line 43, and a third negative pressure line 44. The first negative pressure line 42 is connected to the vacuum generator 41 and the air slip ring 50. The second negative pressure line 43 is connected to the vacuum generator 41 and the negative pressure switch 471. The second negative pressure line 43 is equipped with a speed regulating valve. The third negative pressure line 44 is connected to the negative pressure switch 471 and a gas source 60. The gas source 60 is a gas storage tank. The negative pressure switch 471 is configured to switch the on / off state between the first negative pressure line 42 and the second negative pressure line 43 when the rotating seat 10 rotates to a specified angle.
[0110] Specifically, when the pneumatic assembly 40 needs to put the airflow passage into a vacuum state, the negative pressure switch 471 is opened, and the first negative pressure pipeline 42 and the second negative pressure pipeline 43 are connected. At this time, the vacuum generator 41 and the air slip ring 50 form an airflow passage through the first negative pressure pipeline 42 and the second negative pressure pipeline 43. The vacuum generator 41 can extract the air in the air passage of the air slip ring 50, so that the adsorption stage 20 connected to the air slip ring 50 can adsorb the material 400.
[0111] When the pneumatic assembly 40 needs to put the airflow passage in a vacuum-breaking state, the negative pressure switch 471 is closed, and the first negative pressure pipeline 42 and the second negative pressure pipeline 43 are disconnected. At this time, the vacuum generator 41 and the air slip ring 50 do not form an airflow passage through the first negative pressure pipeline 42 and the second negative pressure pipeline 43, preventing the vacuum generator 41 from drawing air from the air passage of the air slip ring 50, and causing the adsorption stage 20 connected to the air slip ring 50 to release the material 400.
[0112] Thus, when the rotating seat 10 rotates to the specified angle, the airflow passage can be switched to a vacuum state or a vacuum breaking state by controlling the switching state of the negative pressure switch 471.
[0113] In some embodiments, each pneumatic assembly 40 further includes a vacuum breaking switch 472, a first vacuum breaking line 45, and a second vacuum breaking line 46. The first vacuum breaking line 45 is connected to the vacuum breaking switch 472 and the air slip ring 50, and is equipped with a speed regulating valve. The second vacuum breaking line 46 is connected to the vacuum breaking switch 472 and the gas source 60. The vacuum breaking switch 472 is configured to switch the on / off state between the first vacuum breaking line 45 and the second vacuum breaking line 46 when the rotating seat 10 rotates to a specified angle.
[0114] Specifically, when the pneumatic component 40 needs to put the airflow passage in a vacuum-breaking state, the negative pressure switch 471 is closed and the vacuum-breaking switch 472 is opened, and the first vacuum-breaking pipeline 45 and the second vacuum-breaking pipeline 46 are connected. At this time, the gas source 60 and the air slip ring 50 are connected through the first vacuum-breaking pipeline 45 and the second vacuum-breaking pipeline 46. The gas source 60 provides air to the air passage of the air slip ring 50 to assist the adsorption stage 20 connected to the air slip ring 50 in releasing the material 400.
[0115] When the pneumatic assembly 40 needs to put the airflow passage into a vacuum state, the negative pressure switch 471 is opened and the vacuum breaking switch 472 is closed, and the first vacuum breaking pipeline 45 and the second vacuum breaking pipeline 46 are disconnected. At this time, the gas source 60 and the air slip ring 50 are not connected by the first vacuum breaking pipeline 45 and the second vacuum breaking pipeline 46. The gas source 60 does not supply air to the air passage of the air slip ring 50 temporarily, so as to allow the adsorption stage 20 connected to the air slip ring 50 to release the material 400.
[0116] In some embodiments, the negative pressure switch 471 and the vacuum breaking switch 472 are integrated into a dual-electro-controlled solenoid valve 47. The dual-electro-controlled solenoid valve 47 has a first port and a second port, and the second port is closed when the first port is open, and the first port is closed when the second port is open. The first port of the dual-electro-controlled solenoid valve 47 constitutes the negative pressure switch 471, and the second port of the dual-electro-controlled solenoid valve 47 constitutes the vacuum breaking switch 472. A second negative pressure line 43 and a third negative pressure line 44 are respectively connected to the first port of the dual-electro-controlled solenoid valve 47, and a first vacuum breaking line 45 and a second vacuum breaking line 46 are respectively connected to the second port of the dual-electro-controlled solenoid valve 47.
[0117] In this way, the dual-electro-controlled solenoid valve 47 can simultaneously realize the functions of both the negative pressure switch 471 and the vacuum breaking switch 472, simplifying the hardware structure, reducing the space occupied by the components, and making the design more ingenious.
[0118] In some embodiments, the first vacuum breaking line 45 is connected to the first negative pressure line 42, and the connection point between the first vacuum breaking line 45 and the first negative pressure line 42 is located between the air slip ring 50 and the vacuum generator 41.
[0119] It is understood that one end of the first vacuum breaking pipeline 45 is connected to the vacuum breaking switch 472, and the other end of the first vacuum breaking pipeline 45 is connected to the first negative pressure pipeline 42, and then connected to the air slip ring 50 through the first negative pressure pipeline 42. In this way, the total length of the pipeline can be shortened, the pipeline structure can be simplified, and the space occupied can be reduced.
[0120] In some embodiments, each group of air pressure components 40 further includes an air pressure detection element 48, which is connected to the first negative pressure pipeline 42. For example, the air pressure detection element 48 is a digital pressure sensor, which is used to detect the air pressure in the first negative pressure pipeline 42 to obtain air pressure information. The air pressure information can be used to determine whether the corresponding airflow passage is in a vacuum state, so as to monitor the implementation of the adsorption function.
[0121] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application and are not intended to limit it. Although this application has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this application without departing from the spirit and scope of the technical solutions of this application.
