Abstract
Description
Technical Field
[0001] This application belongs to the field of laser processing technology, and more specifically, relates to a pickup device and laser processing equipment. Background Technology
[0002] In the production process, to improve production cycle time and save space, the spacing between adjacent workpieces on the loading pallet is generally set small. However, because subsequent processes require operating space, the spacing between workpieces on the conveyor line cannot be set too small; otherwise, it will cause spatial interference during the operation of the processing equipment. Due to the inconsistency between the workpiece spacing on the loading pallet and the workpiece spacing on the conveyor line, traditional robotic arms can only load single workpieces, resulting in low work efficiency and a production cycle time that cannot meet production requirements.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.
[0035] Please see Figure 1 and Figure 2 The pickup device provided in the embodiments of this application will now be described. The pickup device provided in the embodiments of this application includes a mounting frame 1, a plurality of pickup components 2, a pitch-changing mechanism 3, and a pitch-changing adjustment component 4. The plurality of pickup components 2 are sequentially mounted on the mounting frame 1 along a first direction for picking up workpieces; the pitch-changing mechanism 3 is mounted on the mounting frame 1 and includes a drive component 31 and a pitch-changing component 32. The pitch-changing component 32 is connected to the plurality of pickup components 2, and the drive component 31 is drively connected to the pitch-changing component 32 so that the pitch-changing component 32 adjusts the distance between the plurality of pickup components 2; the pitch-changing adjustment component 4 is mounted on the mounting frame 1 and can abut against the pitch-changing component 32 or the drive component 31 for limiting the maximum value of the distance between the plurality of pickup components 2.
[0036] In this embodiment, the mounting frame 1 is the basic structure of the entire pickup device, used to support and fix other components. The mounting frame 1 can be made of high-strength metal materials (such as aluminum alloy or steel) to ensure sufficient strength and stability. The shape of the mounting frame 1 can be designed according to actual production needs; for example, it can be designed as a rectangular frame structure to facilitate installation and layout. The mounting frame 1 may include a top plate, a left side plate, and a right side plate. The left side plate and the right side plate are mounted opposite each other on both sides of the top plate. The first direction can specifically be the length direction of the mounting frame.
[0037] Pick-up component 2 is used to pick up workpieces (such as cylindrical lithium batteries or cells). Pick-up component 2 is specifically a gripper or other structure suitable for grasping workpieces.
[0038] The pitch mechanism 3 includes a drive assembly 31 and a pitch conversion assembly 32.
[0039] The drive assembly 31 can be driven by a motor. For example, a stepper motor can be used as the power source, and the precise driving of the pitch-changing assembly 32 can be achieved by precisely controlling the number of steps of the motor. The output shaft of the motor is connected to the pitch-changing assembly 32 via a coupling. The control signal of the motor can be provided by an external controller (such as a PLC or microcontroller), which can send instructions according to the needs of the production process to control the forward and reverse rotation and speed of the motor, thereby realizing the dynamic adjustment of the gap of the pickup assembly 2. The drive assembly 31 can also be a cylinder or a hydraulic cylinder.
[0040] The pitch-changing assembly 32 can specifically be a telescopic rod with several telescopic tubes nested sequentially along a first direction, with each telescopic tube connected to a pickup assembly 2. The drive assembly 31 is connected to one end of the telescopic tube of the telescopic rod, and increases or decreases the distance between the pickup assemblies 2 by pulling the telescopic tube along the first direction.
[0041] The pitch adjustment assembly 4 is used to limit the maximum distance between the pickup components 2 to ensure that the excessive distance between the pickup components 2 during adjustment will not cause interference with other devices. The pitch adjustment assembly 4 may include a stop and a threaded fastener. The mounting bracket 1 is provided with an oblong hole for fine-tuning the position of the stop. The threaded fastener passes through the oblong hole to connect with the stop. The stop is used to abut against the pitch adjustment assembly 32 or the drive assembly 31 to limit the maximum distance between several pickup components 2.
[0042] The picking device in this embodiment can flexibly adjust the spacing between several picking components 2 through the pitch-changing mechanism 3, so that the spacing between the picking components 2 meets the needs of different scenarios. The adjusted spacing of the picking components 2 can well match the requirements of the conveyor line and subsequent processes for workpiece spacing, ensuring the smooth connection of the entire production process. This flexible spacing adjustment capability avoids the inefficiency problem of traditional robotic arms requiring frequent single operations due to mismatched spacing, improves work efficiency, speeds up the production cycle, and meets production requirements.
[0043] Preferably, the pitch adjustment assembly 4 includes a limiting member 41 and an adjusting member 42. The adjusting member 42 is mounted on the mounting frame 1 and is connected to the limiting member 41. The adjusting member 42 is used to adjust the position of the limiting member 41 on the mounting frame 1. The limiting member 41 is used to abut against the pitch adjustment assembly 32 or the drive assembly 31 to limit the maximum value of the distance between several pickup assemblies 2.
[0044] The adjusting component 42 can be a motor, cylinder or hydraulic cylinder installed on the mounting frame 1. Taking a motor as an example, the limiting component 41 is connected to the drive shaft of the motor. When the motor rotates, the position of the limiting component 41 on the mounting frame 1 can be adjusted. When the pitch component 32 or the drive component 31 moves to contact the limiting component 41, the limiting component 41 prevents the pitch component 32 or the drive component 31 from continuing to move, thereby limiting the maximum value of the distance between the picking components 2.
[0045] Preferably, the adjusting member 42 is provided with an external thread, and the limiting member 41 is provided with a threaded hole. The adjusting member 42 and the limiting member 41 are connected by threads to adjust the position of the limiting member 41 on the mounting bracket 1.
[0046] The limiting component 41 can be a limiting block or a baffle, and the adjusting component 42 can be a screw or a bolt.
[0047] The limiting component 41 is mounted on the mounting bracket 1 and located on the moving path of the pitch-changing assembly 32. The adjusting component 42 can adjust the position of the limiting block. For example, by adjusting the adjusting screw, the maximum distance between the pickup assemblies 2 can be limited to a range suitable for the conveyor line requirements, such as 50 mm. In this way, even in the event of an unexpected situation, the distance between the pickup assemblies 2 will not exceed this maximum value when adjusting the distance, ensuring the safe operation of the equipment and the smooth progress of the production process.
[0048] Preferably, the variable pitch assembly 32 includes a scissor cross arm 321, a movable support 322, and a plurality of follower supports 323. The movable support 322 and the plurality of follower supports 323 are equidistantly distributed along a first direction and connected to the scissor cross arm 321. Pickup components 2 are connected to the movable support 322 and the plurality of follower supports 323. The movable support 322 is connected to the drive assembly 31. The drive assembly 31 drives the movable support 322 to move along the first direction, so that the scissor cross arm 321 extends and retracts to adjust the spacing between the pickup components 2.
[0049] The follower support 323, which is furthest from the movable support 322, or one end of the scissor cross arm 321 connected to it, can be fixedly mounted on the mounting frame 1. The drive assembly 31 can be connected to the movable support 322 via a lead screw and a nut. The drive assembly 31 is connected to the lead screw to drive the lead screw to rotate forward or backward. The nut is threadedly connected to the lead screw and to the movable support 322. The movable support 322 is connected to the guide rail on the mounting frame 1. The length direction of the guide rail and the length direction of the lead screw are both parallel to the first direction. The drive assembly 31 drives the lead screw to rotate, which moves the nut along the first direction, thereby extending and retracting the scissor cross arm 321, thus adjusting the spacing between the pickup assemblies 2.
[0050] In addition, the drive assembly 31 can be directly connected to the movable support 322 via its drive shaft, or the drive assembly 31 can be directly connected to the scissor cross arm 321 to drive the scissor cross arm 321 to extend and retract in the first direction.
[0051] The scissor crossarm 321 includes several cross sections, each cross section including a pivot 3211, a first hinge secondary section 3212 and a second hinge secondary section 3213. The first hinge secondary section 3212 and the second hinge secondary section 3213 are stacked crosswise and rotatably connected by the pivot 3211. The first hinge secondary section 3212 of the cross section is rotatably connected to the second hinge secondary section 3213 of the adjacent cross section. The pivot 3211 is inserted into the movable support 322 or the follower support 323.
[0052] The first hinge sub-part 3212 of each intersection is rotatably connected to the second hinge sub-part 3213 of the adjacent intersection via a pivot 3211, forming a continuous scissor crossarm 321 structure. This structure allows the scissor crossarm 321 to extend and retract under the action of the drive assembly 31, thereby adjusting the spacing between the pickup assemblies 2.
[0053] The pitch control assembly 32 also includes a guide 324, which is connected to the movable support 322 and several follower supports 323.
[0054] The guide member 324 can specifically be a guide rail mounted on the mounting base. The guide member 324 is used to ensure the smoothness and accuracy of the movable support 322 and the follower support 323 during movement. The guide member 324 is arranged along a first direction.
[0055] Preferably, the guide member 324 includes a guide portion 3241 and a sliding portion 3242. The guide portion 3241 is mounted on the mounting bracket 1, and the sliding portion 3242 is sleeved on the guide portion 3241. The sliding portion 3242 is disposed on the movable support 322 or the follower support 323.
[0056] The guide part 3241 can be a guide shaft installed on the mounting bracket 1, and the sliding part 3242 can be a linear bearing that is slidably disposed on the guide part 3241. The sliding part 3242 is installed on the movable support 322 or the follower support 323 by bolts.
[0057] For preferred options, please refer to [link / reference]. Figure 3 , Figure 4 The pickup component 2 includes an adsorption element 21 and a connecting pipe 22. The movable support 322 and several follower supports 323 are each provided with an air pipe 3221 connected to an external vacuum device. The adsorption element 21 is connected to the air pipe 3221 through the connecting pipe 22.
[0058] The adsorption element 21 can be a vacuum suction cup made of rubber, which can firmly adsorb the workpiece. Compared with the gripper, the adsorption element 21 requires less space and is less likely to interfere with adjacent adsorption elements 21.
[0059] The connecting pipe 22 is used to connect the adsorption element 21 to an external vacuum device. Both the movable support 322 and the follower support 323 are equipped with air pipes 3221 for connecting to the external vacuum device. One end of the connecting pipe 22 is connected to the vacuum suction cup, and the other end is connected to the air pipe 3221.
[0060] The pickup assembly 2 also includes a manifold (not shown in the figure) and several adapters 23. The adapters 23 are connected to the air pipe 3221, the manifold is connected to several adapters 23, and the manifold is connected to an external vacuum device.
[0061] In this embodiment, the adapter 23 can be a quick connector, with one end of each adapter 23 connected to the air tube 3221 and the other end connected to the manifold. The quick connector design of the adapter 23 allows for quick connection and disconnection of the air tube 3221 and the manifold, facilitating maintenance and replacement of the adsorption element 21, and improving the flexibility and maintainability of the equipment.
[0062] The manifold is used to connect multiple adapters 23 to an external vacuum device. The manifold can be made of rigid plastic or metal, possessing sufficient strength and airtightness. Multiple air inlets are provided on the manifold and connect to the adapters 23, while the air outlet of the manifold connects to the external vacuum device.
[0063] Through the design of the manifold and adapter 23, multiple adsorption units 21 can share an external vacuum device, reducing the number and cost of vacuum equipment while improving the reliability and ease of maintenance of the system.
[0064] The compact layout of the manifold and adapter 23 saves space, making the entire pickup device more concise and adaptable.
