[0053] The X-ray detection equipment provided in the embodiment of the present invention is mainly used to detect unqualified batteries and sort them out, wherein the batteries mainly refer to button batteries, that is, the batteries are button-shaped and have two pins. The X-ray detection equipment mainly detects whether the two pins are normal in a low-cost and efficient manner.

[0054] like Figure 1 As shown, the X-ray detection device of the present invention comprises a feeding device 1 and a discharging device 9; and further comprises a circulating conveying device 3 for conveying the batteries placed on the discharging position of the feeding device 1 to the feeding position of the discharging device 9;

[0055] The circulating conveying device 3 is provided with an X-ray detection device 4 and an NG discharging device 6 for detecting whether the battery is qualified in sequence along its battery conveying direction; the X-ray detection device 4 and the NG discharging device 6 are both electrically connected to the main control module; the main control module is used to mark the battery detected as unqualified by the X-ray detection device 4 as the first NG battery;

[0056] The circulating conveying device 3 includes an NG discharging PPU robot 5 for conveying the first NG battery from the NG discharging position of the circulating conveying device 3 to the NG loading position of the NG discharging device 6; the NG discharging PPU robot 5 is electrically connected to the main control module, and is used to clamp the first NG battery onto the NG discharging device 6.

[0057] It should be added that the battery conveying direction refers to the trajectory of the battery after being clamped to the circulating conveying device 3; the discharge position refers to the position where the battery is located on the feeding device 1 and can be clamped by the feeding PPU robot 2; the feeding position refers to the position where the battery is clamped by the feeding PPU robot 2 and moved to the circulating conveying device 3; the NG discharge position refers to the position where the battery is located on the circulating conveying device 3 and can be clamped by the NG discharge PPU robot 5; the NG feeding position refers to the position where the battery is clamped by the NG discharge PPU robot 5 and moved to the NG discharge device 6. The discharging device 9 of the X-ray detection equipment is located on one side of the circulating conveying device 3, and qualified batteries are discharged by a discharging PPU robot; the PPU robot refers to a pure cam structure transfer robot, and the grasped batteries can be moved along a predetermined trajectory under the action of a servo or stepper motor, wherein the feeding PPU robot 2, the NG discharging PPU robot 5 and the discharging PPU robot in this embodiment all include two workstations; for the feeding PPU robot 2, one workstation is on the feeding device 1, and the other workstation is on the circulating conveying device 3; for the NG discharging PPU robot 5, one workstation is on the NG discharging device 6, and the other workstation is on the circulating conveying device 3; for the discharging PPU robot, one workstation is on the discharging device 9, and the other workstation is on the circulating conveying device 3. The circulating conveying device 3, the feeding device 1, the X-ray detection device 4, the NG discharging device 6, the feeding PPU robot 2, the NG discharging PPU robot 5, the discharging device 9 and the discharging PPU robot are all arranged on the bottom plate of the X-ray detection equipment.

[0058] Among them, the discharging device 9 includes a discharging conveyor belt, which is connected to a discharging drive device for driving the discharging conveyor belt to rotate; when the qualified battery moves to the OK discharging position of the circulating conveyor device 3, the OK discharging PPU manipulator arranged next to the circulating conveyor device 3 takes the qualified battery out from the OK discharging position and puts it into the discharging conveyor belt to realize the discharge of the qualified battery.

[0059] Specifically, the battery is clamped from the discharge position to the circulating conveyor 3 by the feeding PPU manipulator 2, and then the battery on the circulating conveyor 3 is inspected by the X-ray detection device 4; when the X-ray detection device 4 detects that a battery is unqualified and feeds it back to the main control module, the main control module marks it as the first NG battery; when the circulating conveyor 3 conveys the first NG battery to the NG discharge position, the NG discharge PPU manipulator 5 clamps the first NG battery to the NG discharge device under the control of the main control module. Since the circulating conveyor 3 is controlled by the main control module, the position of the first NG battery can be tracked, so there is no need for mechanical visual positioning, nor for a high-degree-of-freedom robot arm. The first NG battery can be sorted only by tracking the first NG battery through the main control module and the low-cost PPU manipulator. In addition, the automation of X-ray detection and sorting of button batteries is realized, which improves production efficiency, significantly increases production capacity to 60 per minute, and reduces production costs.

[0060] Furthermore, if Figure 4 As shown, the circulating conveying device 3 includes an annular transmission belt 33, and a slide rail 35 is arranged around the outer side of the transmission belt 33;

[0061] A plurality of slide blocks for fixing and installing the battery clamp 34 are slidably connected to the slide rail 35 ; the battery clamp 34 is fixedly connected to the transmission belt 33 ; the transmission belt 33 is connected to a driving device for driving the transmission belt 33 to rotate.

[0062] Specifically, the driving device includes a driven wheel 31 and a driving wheel 32; a transmission belt 33 is tensionedly sleeved on the driven wheel 31 and the driving wheel 32;

[0063] The driving wheel 32 is connected to a power device for driving the driving wheel 32 to rotate.

[0064] Specifically, the battery clamp 34 is connected to a plurality of battery fixing seats 341 for fixing the batteries; the driving wheel 32, the transmission belt 33, the battery clamp 34 and the battery fixing seat 341 are arranged in sequence from the inside to the outside; wherein, the slide rail 35 is located between the transmission belt 33 and the battery fixing seat 341, which can shift the center of gravity of the battery clamp 34 toward the slide rail 35, thereby reducing the displacement of the battery clamp 34 relative to the slide rail 35, thereby improving the anti-bias pressure capability and improving the stability of the circulating conveying device 3; in addition, when the battery conveying path is determined, the slide rail 35, the conveyor belt 33 and the driving wheel 32 are arranged inwardly in sequence, so that the transmission part is closer to the driving device, the rotational inertia is reduced, and the transmission accuracy is improved; in addition, the battery clamp 34 is provided with a weight-reducing hole, which is also used to reduce the rotational inertia.

[0065] Furthermore, if Figure 2As shown, the feeding device 1 comprises a feeding conveyor belt 11 for conveying the batteries to the discharge position; the feeding conveyor belt 11 is connected to a feeding drive device 12 for driving the feeding conveyor belt 11 to rotate;

[0066] The discharge position includes at least two equally spaced separation positions; a separation mechanism 14 for moving the batteries into the separation positions is provided on one side of the discharge position of the feeding device 1 .

[0067] It should be added that the feed guardrail 13 is fixed to the feed base of the feed device 1 by a bolt, and the feed base is provided with an adjustment slot, and the distance between the two feed guardrails 13 can be adjusted by adjusting the position of the bolt in the adjustment slot to match different batteries. After the battery reaches the feed position, the sensor of the feed device 1 will be triggered. In this embodiment, the number of batteries is 6. When 6 batteries enter the feed position, the sensor will be triggered, thereby performing a material separation operation on the 6 batteries, which is convenient for the subsequent feed PPU manipulator to grab them, thereby improving the grabbing accuracy.

[0068] Furthermore, if Figure 2 As shown, the material separation mechanism 14 includes a separation mechanism 142 for moving the battery into the separation position; the separation mechanism 142 is connected to a positioning cylinder 141 for pushing the separation mechanism 142 to press the battery. When the battery is transported to the feeding position, the positioning cylinder 141 is used to push the separation mechanism 142 to abut against the battery to position the battery; the separation mechanism 142 is used to separate the positioned batteries. First, the separation mechanism 142 is pushed by the positioning cylinder 141 to press the battery, and then the separation mechanism 142 separates the compressed battery; in this embodiment, the number of batteries separated each time is 6, so that the spacing between the batteries is equal, which is convenient for the feeding PPU manipulator 2 to clamp the battery, improves the positioning accuracy of the battery, reduces the positioning cost, and improves the positioning efficiency.

[0069] Based on the above embodiments, Figure 3 As shown, the spacing mechanism 142 includes a spacing cylinder 1421 and a spacing fixing seat 1422; the spacing cylinder 1421 is arranged on the spacing fixing seat 1422;

[0070] At least two spacing blocks 1423 are arranged on the spacing fixing seat 1422. The spacing blocks 1423 are arranged along the telescopic direction of the spacing cylinder 1421. A connecting block 1424 is arranged between two adjacent spacing blocks 1423. One end of the connecting block 1424 is fixedly connected to the spacing block 1423 close to the spacing cylinder 1421, and the other end is slidably connected to the spacing block 1423 far away from the spacing cylinder 1421; the spacing block 1423 farthest from the spacing cylinder 1421 is fixedly connected to the telescopic end of the spacing cylinder 1421;

[0071] When the telescopic end of the positioning cylinder 141 is extended, the spacing fixing seat 1422 is pushed by the positioning cylinder 141 so that the battery is pressed and positioned by the spacing block 1423;

[0072] When the battery is positioned and the spacing cylinder 1421 is retracted, the spacing block 1423 connected to the spacing cylinder 1421 is pulled by the spacing cylinder 1421 to be located at the corresponding spacing position, and the remaining spacing blocks 1423 are pushed by adjacent spacing blocks 1423 to be located at the corresponding spacing positions.

[0073] It should be noted that when the spacing cylinder 1421 retracts, the spacing block 1423 connected to the spacing cylinder 1421 is pulled to the spacing position by the spacing cylinder 1421, and the spacing position refers to the position where the feeding PPU manipulator 2 clamps the battery; wherein, the spacing block 1423 connected to the spacing cylinder 1421 will push the remaining spacing blocks 1423 to the corresponding spacing position during the process of moving to the spacing position; when resetting, the spacing cylinder 1421 drives the spacing block 1423 connected thereto to reset, and the spacing block 1423 drags the remaining spacing blocks 1423 to reset in turn through the connecting block 1423. This spacing method only requires the spacing cylinder 1421 as a power source, and can be driven to reset through the connecting block 1423, thereby improving the spacing accuracy, and is simple and reliable.

[0074] Furthermore, if Figure 1 As shown, the X-ray inspection device is also provided with a scanning device 7 for scanning the two-dimensional code information of the battery and tracing whether the battery is qualified along the battery conveying direction of the circulating conveying device 3;

[0075] The code scanning device 7 is arranged between the feeding device 1 and the NG discharging device 6, and is electrically connected to the main control module. The main control module is also used to mark the battery traced back as unqualified by the code scanning device 7 as the second NG battery.

[0076] Furthermore, if Figure 1 As shown, the X-ray detection equipment is also provided with a battery sensing device 8 for sensing whether a battery exists on the circulating conveying device 3 along its battery conveying direction; the battery sensing device 8 is arranged between the feeding device 1 and the code scanning device 7.

[0077] Furthermore, if Figure 8 As shown, the NG discharging PPU manipulator 5 is connected to an NG discharging fixing seat 51, and a suction cup 52 for clamping the first NG battery or the second NG battery is provided on the NG discharging fixing seat 51;

[0078] When the NG discharging PPU robot 5 clamps the battery from the NG discharging position of the circulating conveying device 3, the NG discharging fixed seat 51 is located at the first stroke position; when the NG discharging PPU robot 5 puts the battery into the NG loading position of the NG discharging device 6, the NG discharging fixed seat 51 is located at the second stroke position; the plane where the first stroke position is located is parallel to the plane where the second stroke position is located.

[0079] In a specific embodiment, Figure 5 and Figure 8 As shown, the NG discharging device 6 is provided with two suction cups 52 at intervals along its discharging direction; one of the suction cups 52 is used to grab the first NG battery, and the other suction cup 52 is used to grab the second NG battery;

[0080] The NG discharging device 6 includes an NG discharging conveyor belt 61; the NG discharging conveyor belt 61 is connected to an NG discharging driving device 62 for driving the NG discharging conveyor belt 61 to rotate;

[0081] Two guardrails 63 are respectively provided on both sides of the NG discharging conveyor belt 61; a partition 64 is connected between the two guardrails 63; the partition 64 separates the NG discharging conveyor belt 61 into two channels 66; an NG discharging cylinder 65 for pushing the first NG battery into the corresponding channel 66 or the second NG battery into the corresponding channel 66 is provided on one side of the NG feeding position. Exemplarily, the upper channel 66 is used to recycle the first NG battery, and the lower channel 66 is used to recycle the second NG battery. After the NG discharging PPU manipulator 5 puts the second NG battery into the upper channel, the NG discharging cylinder 65 pushes the second NG battery into the lower channel. In the above manner, there is no need to further optimize the path of the NG discharging PPU manipulator 5 or increase the number of NG discharging PPU manipulators 5, thereby reducing costs.

[0082] Furthermore, if Figure 6 As shown, the X-ray detection device 4 includes two X-ray detection modules 41, one X-ray detection module 41 is used to detect the first pin of the battery, and the other X-ray detection module 41 is used to detect the second pin of the battery.

[0083] In summary, the X-ray detection equipment provided by the embodiment of the present invention reduces the cost of battery sorting and improves transmission accuracy.
