DETAILED DESCRIPTION

In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

This embodiment relates to a battery cover plate processing device, in order to optimize the structure of the processing device and improve the processing efficiency of the battery cover plate 5.

In terms of overall structure, the battery cover processing device includes a coding mechanism, a coding detection mechanism, a classification mechanism and a transfer mechanism arranged in sequence. Among them, the coding mechanism is used to engrave patterns at preset positions of several cover plates 5, and the coding detection mechanism is used to detect whether the patterns are qualified. The classification mechanism includes a plurality of qualified product placement parts and unqualified product placement parts. The qualified product placement part is used to place the cover plates 5 with qualified coding, and the unqualified product placement part is used to place the cover plates 5 with unqualified coding. The transfer mechanism is used to clamp each cover plate 5 and transfer the cover plates 5 to the coding mechanism, the coding detection mechanism, the qualified product placement part or the unqualified product placement part in sequence.

The battery cover processing device described in this embodiment clamps the cover 5 through the transfer machine and transfers the cover 5 to the coding mechanism, the coding detection mechanism, the qualified product placement part or the unqualified product placement part in sequence, which is beneficial to the coding, coding detection and classification of the cover 5. Compared with the traditional mechanical module to transfer the cover 5, it is beneficial to reduce the positioning of the cover 5. The number of times and good transfer flexibility are beneficial to improving the processing efficiency of the cover plate 5. At the same time, it is also beneficial to reduce the loss of mechanical parts, thereby having the effect of reducing production costs.

Based on the overall introduction above, an exemplary structure of the battery cover processing device described in this embodiment is shown in Figure 1. As a preferred embodiment, as shown in Figure 2, the transfer mechanism in this embodiment is a six-axis robot 2 in the prior art, which is also called an industrial robot. The industrial robot is a multifunctional machine that can automatically control positioning and recompile programs to change. The six-axis robot 2 is mainly composed of three parts: a hand, a motion mechanism, and a control system. The hand is a component used to grasp the workpiece (or tool), and there are various structural forms according to the shape, size, weight, material and operation requirements of the grasped object, such as clamping type, supporting type and adsorption type.

Among them, the motion mechanism of the industrial robot enables the hand to complete various rotations (swings), movements or compound movements to achieve the specified actions and change the position and posture of the grasped object. The independent movement modes of the motion mechanism, such as lifting, telescoping, and rotating, are called the degrees of freedom of the robot. The six-axis robot arm 2 in this embodiment has six degrees of freedom. The control system of the six-axis robot arm 2 completes specific actions by controlling the motors of each degree of freedom of the robot. At the same time, it receives information fed back by external sensors to form a stable closed-loop control. The core of the control system is usually composed of a microcontroller such as a single-chip microcomputer, and the desired functions are realized by programming it.

The transfer mechanism in this embodiment adopts a six-axis robot arm 2, which can realize the free movement of the cover plate 5 in each processing station and has good movement flexibility. Compared with the solution of using multiple mechanical modules to clamp and transfer the cover plate 5 in the prior art, it is beneficial to reduce positioning operations and has the advantages of high transfer accuracy and efficiency.

In order to facilitate the grabbing of the cover plate 5, the transfer mechanism is provided with a plurality of groups of clamping jaws 302 for clamping each cover plate 5, and a first cylinder for driving two clamping jaws 302 in each group to move closer or farther away. Here, the two clamping jaws 302 are driven closer or farther away from each other by the first cylinder, which facilitates the picking and placing of the cover plate 5 and facilitates the arrangement and implementation.

As a preferred embodiment, the transfer mechanism is provided with four groups of jaws 302, so as to be able to clamp and transfer four cover plates 5 at the same time. Of course, the number of groups of jaws 302 on the transfer mechanism can also be adaptively increased or decreased according to the use requirements, as long as the use requirements are met. As shown in Figures 3 and 4, in order to facilitate the arrangement of the four groups of jaws 302, a mounting plate 3 is provided on the hand of the six-axis robot 2, and the four groups of jaws 302 are arranged at intervals along the length direction of the mounting plate 3.

Two clamping jaws 302 in each group of clamping jaws 302 are arranged on the clamping jaw seat 304, and the two clamping jaws 302 are slidably arranged on the clamping jaw seat 304 along the width direction of the mounting plate 3. The first cylinder mentioned above is also provided on the clamping jaw seat 304. The two clamping jaws 302 can clamp the cover plate 5 in the thickness direction of the cover plate 5 under the driving of the first cylinder. FIG3 shows a schematic diagram of the structure of the cover plate 5 in the initial state of feeding. At this time, the outer side surface of the cover plate 5 is arranged upward, and the engraving area 300 to be engraved is located outside the clamping jaws 302.

In order to further improve the flexibility of the use of the clamping jaws 302, the distance between two adjacent groups of clamping jaws 302 in this embodiment can be Adjustable, so that it can adapt to different code engraving spacing and detection spacing, etc. Specifically, as shown in Figure 3, each clamping jaw seat 304 is slidably arranged on the guide rail 301 of the mounting seat along the length direction of the mounting plate 3. Second cylinders for driving each clamping jaw seat 304 to slide are also respectively arranged on the mounting plate 3. When it is necessary to adjust the spacing between the two groups of clamping jaws 302, the control system on the six-axis robot 2 sends a start-stop signal to each second cylinder, so that the spacing between the upper cover plates 5 of the two adjacent groups of clamping jaws 302 can be adjusted to the target spacing to meet the use requirements of code engraving and code engraving detection, as well as classified placement.

In addition, as shown in Figures 3 and 4, a third detection unit 303 for detecting whether there is a cover plate 5 on the clamping jaw 302 is also provided on the clamping jaw seat 304. The third detection unit 303 here can send the detection information to the control system of the six-axis robot arm 2. In specific implementation, the third detection unit 303 can be a product with a position detection function such as a position sensor.

The battery cover processing device in this embodiment is shown in FIG1 , and further includes a workbench 1. The above-mentioned coding mechanism, coding detection mechanism and classification mechanism are all arranged on the workbench 1, and the transfer mechanism is located on one side of the workbench 1. The coding mechanism in this embodiment includes a plurality of coding devices 6 arranged one by one corresponding to the cover plates 5, and a dust cover 7 located between the coding devices 6 and the cover plates 5. The dust cover 7 is provided with a through hole 701 located on the coding path of each coding device 6, and the cover plates 5 can abut against the dust cover 7, and the coding area 300 of each cover plate 5 is exposed to the through hole 701.

Here, by setting up a plurality of coders 6 corresponding to the cover plate 5 one by one, the code area 300 on the cover plate 5 can be coded at the same time, and the dust cover 7 and the through hole 701 thereon are used to collect impurities generated during the coding process, thereby reducing the pollution to the surrounding environment during the coding process.

In terms of specific structure, as shown in FIG5 , the coding mechanism is also provided with four code cutters 6. To facilitate the installation of the code cutters 6, a mounting frame 101 is provided on the workbench 1. The four code cutters 6 are arranged on the mounting frame 101 at intervals along the length direction of the workbench 1. The code cutters 6 here can be laser code cutters 6 in the prior art. The pattern formed by the code cutters 6 in the coding area 300 of the cover plate 5 can be a two-dimensional code to improve the convenience of obtaining battery information. Of course, the specific shape and purpose of the pattern can be adjusted according to the use requirements.

In this embodiment, the transfer mechanism drives the mounting plate 3 to rotate so that the coding area 300 of each cover plate 5 is set toward the dust cover 7, and the cover plate 5 is transferred to the coding station so that the coding area 300 of each cover plate 5 is set toward the corresponding coder 6. The dust cover 7 is located between the four coders 6 and the four cover plates 5, the bottom of the dust cover 7 is fixed on the workbench 1, and the top of the dust cover 7 is provided with an outlet for connecting to an external negative pressure device. The outer sides of the four cover plates 5 (mounted on the exposed side of the battery housing) abut against the dust cover 7, and the coding area 300 of each cover plate 5 is located in the through hole 701 and exposed to the through hole 701, so that the laser emitted by the coder 6 can enter through the through hole 701 and act on the coding area 300 of the cover plate 5 to complete the coding.

It should be noted that the number of the encoders 6 in this embodiment can be adaptively increased or decreased according to the use requirements. When the number of the encoders 6 is less than the number of the cover plates 5, the mounting plate 3 and the encoders 6 can be relatively slidable. The coding on each cover plate 5 is realized.

The code detection mechanism in this embodiment includes at least one scanner and a controller 801 electrically connected to the scanner, and the controller 801 is electrically connected to the transfer mechanism. The controller 801 is used to receive scan information, compare the scan information with the preset information stored in itself, and transmit the comparison result to the transfer mechanism. Here, the scanner is set up by sliding to facilitate scanning the pattern on the cover plate 5, and the controller 801 is set up to facilitate identification of whether the pattern is qualified.

The scanner here is a barcode scanner 8 in the prior art, which can recognize a two-dimensional code and determine whether the two-dimensional code is qualified through a controller 801. Specifically, as a preferred embodiment, as shown in FIG6 , two barcode scanners 8 are arranged at intervals along the length direction of the workbench 1. After the code is engraved, the six-axis robot 2 simultaneously transfers the four cover plates 5 to the scanning path of the two barcode scanners 8, and adjusts the distance between the two adjacent cover plates 5 to match the distance between the two barcode scanners 8.

Such an arrangement enables the two barcode scanners 8 to simultaneously scan the two QR codes on the two cover plates 5 at the left end of the mounting plate 3, respectively, and by moving the six-axis robot 2 to the left, the QR codes on the two cover plates 5 on the right side of the mounting plate 3 correspond to the two barcode scanners 8, and the QR codes on the two cover plates 5 are scanned respectively. The barcode scanner 8 in this embodiment can realize fast code reading, thereby helping to improve the detection efficiency. Of course, the number of barcode scanners 8 can also be set in a one-to-one correspondence with the number of cover plates 5, in which case the QR codes on the four cover plates 5 can be scanned and detected simultaneously, thereby further improving the detection efficiency.

The controller 801 in this embodiment stores preset picture information, i.e., two-dimensional code information. When the pattern information (i.e., two-dimensional code information) transmitted by the barcode scanner 8 does not match the pre-stored information, it is considered that the engraving of the cover plate 5 is unqualified. When the two-dimensional code information matches the pre-stored information, it is considered that the engraving of the cover plate 5 is qualified. The controller 801 sends the detection information to the control system of the six-axis robot 2, so that the control system records the unqualified cover plates 5 and the qualified cover plates 5, thereby serving as a basis for classifying the cover plates 5.

As a preferred embodiment, as shown in FIG. 7 and FIG. 8 , the qualified product placement portion in this embodiment includes a plurality of first cover plate grooves 401 slidably arranged along the arrangement direction of the plurality of cover plates 5 in the transfer mechanism, and the unqualified product placement portion includes a plurality of second cover plate grooves 402 arranged at intervals along the arrangement direction of the plurality of cover plates 5 in the transfer mechanism, and the top of the cover plate 5 is respectively exposed in the first cover plate groove 401 or the second cover plate groove 402. Here, the structures of the first cover plate groove 401 and the second cover plate groove 402 are simple, and are easy to arrange and implement. The cover plate 5 is exposed in the first cover plate groove 401 or the second cover plate groove 402, which is convenient for taking and placing the cover plate 5.

Specifically, as shown in FIG. 1 and FIG. 7 , a classification table 4 is provided on the downstream side of the workbench 1 located at the code detection mechanism, and the classification table 4 is located on one side of the six-axis robot arm 2, so that the six-axis robot arm 2 can easily transfer the cover plate 5 to the first cover plate slot 401 or the second cover plate slot 402. As a preferred embodiment, the second cover plate slot 402 is along The workbench 1 is arranged in a plurality of rows on the classification table 4 in the longitudinal direction, and each row has four second cover plate slots 402 arranged at intervals.

The four second cover plate slots 402 correspond to the positions of the four clamped cover plates 5 one by one to ensure that unqualified cover plates 5 can enter the second cover plate slots 402. The first cover plate slot 401 is arranged on one side of the classification table 4 close to the six-axis robot arm 2. The first cover plate slot 401 and the second cover plate slot 402 are both extended along the length direction of the cover plate 5 to place the cover plate 5 arranged horizontally.

The first cover plate slot 401 is arranged closer to the six-axis robot arm 2 than the second cover plate slot 402. The number of the first cover plate slot 401 can be two as shown in the figure, and the two first cover plate slots 401 are slidably arranged on the classification platform 4. In order to drive the first cover plate slots 401 to slide respectively, the classification platform 4 is respectively provided with a third cylinder 405 for sliding each first cover plate slot 401, which is conducive to changing the position of the first cover plate slot 401, so as to receive the qualified cover plate 5.

In addition, to ensure that the cover plate 5 after detection can be placed in the vacant first cover plate slot 401 or the second cover plate slot 402, in this embodiment, a first detection unit 404 for detecting the cover plate 5 is provided on the first cover plate slot 401, and a second detection unit 403 for detecting the cover plate 5 is provided on the second cover plate slot 402, and the first detection unit 404 and the second detection unit 403 are electrically connected to the transfer mechanism respectively. The first detection unit 404 detects whether there is a cover plate 5 in the first cover plate slot 401, and the second detection unit 403 detects whether there is a cover plate 5 in the second cover plate slot 402, and transmits the detection information to the transfer mechanism, which can guide the transfer mechanism to place the cover plate 5, so that the cover plate 5 is accurately placed in the vacant first cover plate slot 401 or the second cover plate slot 402.

As shown in Figure 7, both the first detection unit 404 and the second detection unit 403 can adopt position sensors in the prior art. The first detection unit 404 is arranged on one side of the first cover plate groove 401, and can send a detection line to the other side of the first cover plate groove 401, so as to detect whether there is a cover plate 5 in the first cover plate groove 401, and send the detection information to the control system of the six-axis robot arm 2.

After the code engraving inspection is completed, if there is an unqualified cover plate 5 among the four cover plates 5, the six-axis robot arm 2 moves the four cover plates 5 to the top of a row of second cover plate slots 402 with unloaded second cover plate slots 402, and sets the unqualified cover plate 5 corresponding to the unloaded second cover plate slots 402, and then drives the clamping claws 302 to release the clamping of the unqualified cover plate 5, and the unqualified cover plate 5 can fall into the second cover plate slot 402. After all the unqualified cover plates 5 are placed in the second cover plate slots 402 in this way, the qualified cover plates 5 are moved to the top of the first cover plate slots 401.

The battery cover plate processing device in this embodiment further includes a conveying mechanism located downstream of the classification mechanism, the conveying mechanism is used to convey qualified cover plates 5, and the transfer mechanism can transfer the cover plates 5 of the qualified product placement part to the conveying mechanism. The provision of the conveying mechanism facilitates the conveying of qualified cover plates 5 and further improves the processing efficiency of the cover plates 5.

As a preferred embodiment, as shown in FIG. 1 and FIG. 9 , the classification table 4 is far away from the six-axis robot arm 2. A conveying platform 102 is provided on one side and is arranged vertically with respect to the workbench 1. A conveying mechanism is arranged on the conveying platform 102. The conveying mechanism includes a magnetic suspension rail 103 and a base slidably arranged on the magnetic suspension rail 103. The base is provided with a plurality of clamping plates 104 for clamping each cover plate 5. In this embodiment, the number of clamping plates 104 is also four, so that four qualified cover plates 5 can be conveyed at the same time, thereby improving the conveying efficiency. Of course, the number of clamping plates 104 can also be adaptively increased or decreased according to the use requirements.

In this embodiment, the base slides on the magnetic suspension rail 103, which has the advantages of fast conveying speed and high stability, thereby improving the conveying efficiency of the cover plate 5. According to the test, the maximum speed of the base can reach 2m/s when the load is 20Kg. Of course, in the specific implementation, the conveying mechanism can also use other power methods to drive the base to slide, as long as it meets the use requirements.

When the battery cover plate processing device in this embodiment is used, the cover plate 5 is first loaded onto the clamping jaws 302, and the clamping end of the six-axis robot 2 is specifically moved to the loading position of the cover plate 5, and the four cover plates 5 are clamped and loaded by the clamping jaws 302. Then, the cover plate 5 is engraved, the mounting plate 3 is rotated to adjust the position of the cover plate 5, and the spacing between two adjacent cover plates 5 is adjusted to correspond to the spacing between two adjacent code engravers 6. The six-axis robot 2 simultaneously transfers the four cover plates 5 to the code engraving station, so that the outer sides of the four cover plates 5 abut against one side of the dust cover 7, and the external negative pressure part sucks the gas in the dust cover 7 outward, and the code engraver 6 starts to engrave the two-dimensional code.

Then, the code engraving detection of the cover plate 5 is carried out, and the distance between the two cover plates 5 is adjusted to correspond to the distance between the two barcode scanners 8. The six-axis robot arm 2 moves the four cover plates 5 to the detection station, so that the two barcode scanners 8 first scan and detect the two cover plates 5 on the left, and send the detection information to the controller 801. The controller 801 sends the detection result to the control system, and then moves the mounting plate 3 through the six-axis robot arm 2, so that the two barcode scanners 8 scan and detect the two cover plates 5 on the right. The controller 801 sends the detection information to the control system of the six-axis robot arm 2, and the control system of the six-axis robot arm 2 marks whether the four cover plates 5 are qualified.

Then, the cover plates 5 are classified, and the information on the presence or absence of the cover plates 5 detected by the first detection unit 404 and the second detection unit 403 is sent to the control system of the six-axis robot 2, and the control system of the six-axis robot 2 marks the positions of the empty first cover plate slot 401 and the second cover plate slot 402. Then, the six-axis robot 2 moves four cover plates 5 to the top of the empty second cover plate slot 402, and releases the clamping of the unqualified cover plates 5, so that the cover plates 5 enter the second cover plate slot 402. Then, the six-axis robot 2 moves the remaining qualified cover plates 5 to the top of the empty first cover plate slot 401, and releases the clamping of the qualified cover plates 5, so that the cover plates 5 enter the first cover plate slot 401.

Then, the qualified cover plates 5 are moved. When all the tested cover plates 5 are qualified, the six-axis robot arm 2 directly moves the four cover plates 5 to the loading position of the conveying mechanism, and clamps and positions the four cover plates 5 on the clamping plate 104 for conveying. Put it into the second cover plate slot 402, then move the mounting plate 3 to the top of the first cover plate slot 401, slide the first cover plate slot 401, so that the qualified cover plate 5 corresponds to the clamping claw 302 with the missing cover plate 5, and the clamping claw 302 with the missing cover plate 5 clamps the cover plate 5 until four cover plates 5 are clamped on the mounting plate 3, and the six-axis robot 2 moves the four cover plates 5 to the loading position of the conveying mechanism again. When all the detected cover plates 5 are unqualified, each cover plate 5 is placed in the vacant second cover plate slot 402.

The battery cover processing device described in this embodiment can flexibly transfer the cover 5 through the setting of the six-axis robot arm 2, so that the cover 5 can be coded, detected, classified and transported, which is beneficial to improving the processing efficiency of the cover 5. Compared with the traditional mechanical module for transporting the cover 5, it is beneficial to reduce the number of parts and simplify the operation process, and it is also beneficial to reduce machine loss, thereby reducing production costs.
