Description

Technical Field

[0001] This application relates to the technical field of button batteries, and in particular to a button battery screening device. Background Art

[0002] With the continuous growth of the market demand for button batteries, the terminal application market has higher and higher requirements for the quality of button batteries.

[0003] Before packaging and shipping button batteries, it is necessary to first detect and screen the button batteries to exclude unqualified button batteries. When detecting button batteries, it is necessary to detect multiple dimensions of the button batteries, such as appearance, power, and thickness, so as to better exclude unqualified button batteries. Generally, a CCD camera is first used to take pictures to detect the appearance of the button batteries, and the unqualified products are removed. The qualified products are then transported to the next process for the next detection, and so on, until the qualified products that pass all the detection processes are finally output and packaged.

[0004] However, currently, a receiving box is usually set on one side of the detection device, and the unqualified button batteries after detection are directly put into the receiving box, and the unqualified button batteries in each process are stored and collected together. The unqualified button batteries are stacked and worn against each other, resulting in new quality problems, thus affecting the effect of recycling unqualified button batteries. Summary of the Invention

[0005] In order to solve the problem of mutual stacking and wear of button batteries, this application provides a button battery screening device.

[0006] A button battery screening device provided by this application adopts the following technical solution: A button battery screening device includes a workbench, and several groups of detection components are provided on the workbench. A rotating component is installed on the workbench, and the rotating component is used to position the button batteries; A fixing ring is installed on the rotating component, an installation rod is provided on the fixing ring, an installation block is provided on the installation rod, several groups of pushing components are provided on the installation block, and several groups of receiving components are provided on the side wall of the rotating component, and the pushing components and the receiving components correspond one by one.

[0007] By adopting the above technical solution, the rotating component positions the button batteries, and the rotating component drives the button batteries to be detected during rotation. After the detection is completed, according to the reasons for the unqualified button batteries, they are successively pushed into different receiving components, and the unqualified button batteries are respectively collected, so as to avoid collecting a large number of button batteries together as much as possible, and avoid stacking and wear between button batteries as much as possible.

[0008] In a specific possible implementation scheme, the rotating assembly includes a rotating motor and a rotating disk, the rotating motor is installed on the workbench, the rotating disk is arranged on the output shaft of the rotating motor, the rotating disk is provided with a mounting groove, a plurality of positioning plates arranged circumferentially around the axis of the rotating disk are provided in the mounting groove, a positioning groove for positioning button batteries is provided on the positioning plate, a plurality of limit blocks arranged circumferentially around the axis of the rotating disk are provided on the top wall of the rotating disk, and the surface of the limit block facing the positioning groove is a concave arc surface.

[0009] By adopting the above technical solution, by setting the limit blocks, a positioning cavity can be formed between the two limit blocks and the positioning plate, and the button battery can be placed in the positioning cavity to achieve the positioning of the button battery, and the button battery can be arranged circumferentially along the rotating disk. Under the rotation of the rotating disk, the button battery can be easily moved to different detection components for detection, and the button battery can also be easily removed according to the reason why the button battery is unqualified, which helps to improve work efficiency.

[0010] In a specific feasible implementation scheme, a connecting plate is provided on the fixing ring, a sliding rail is provided on the sliding rail, a sliding block is slidably matched on the sliding rail, a baffle plate is provided on the sliding block, and the pushing assembly includes a pushing cylinder, a pushing rod and a pushing plate, the pushing cylinder is arranged on the mounting block and facing the connecting plate, a transition plate is provided on the piston rod of the pushing cylinder, the pushing plate is arranged on the transition plate, the pushing plate is used to push the button battery out of the positioning groove, one end of the pushing rod is rotatably connected to the pushing plate, and the other end is rotatably connected to the baffle plate, and a baffle groove for the baffle plate to pass through is opened on the fixing ring.

[0011] By adopting the above technical solution, the baffle plate can pass through the baffle groove to block qualified button batteries, and try to prevent qualified button batteries from falling out. When unqualified button batteries are detected, the piston rod of the push cylinder extends to drive the push plate to move toward the side close to the button battery, and at the same time, the push rod drives the baffle plate to rise along the slide rail, so that the push plate can push the unqualified button battery into the receiving assembly, which is convenient for removing the button battery according to the reason why the button battery is unqualified.

[0012] In a specific feasible implementation scheme, a limiting ring is provided at the outer edge of the material guide plate, and the limiting ring is installed on the workbench. The limiting ring is provided with a plurality of material guide grooves arranged at intervals around the axis of the limiting ring, and a material guide plate is provided in the material guide groove. The material receiving assembly includes a material receiving box and a material receiving plate, and the material receiving box is installed on the outer wall of the limiting ring. The end of the material receiving box away from the limiting ring is inclined toward the side close to the workbench, and the material receiving plate is rotatably connected to the material receiving box, and the material guide plate is connected to the material receiving box.

[0013] By adopting the above technical solution, by providing a material guiding plate, it is convenient for unqualified button batteries to enter the material collecting box along the material guiding plate. The material collecting box is inclined, which can facilitate the entry of unqualified button batteries into the material collecting box. The material receiving plate can prevent the button batteries in the material collecting box from falling out. When needed, the button batteries can also be taken out by opening the material receiving plate.

[0014] In a specific feasible implementation, more than one partition is provided in the material collecting box. The partition is arranged along the length direction of the material collecting box. The partition divides the material collecting box into two or more material receiving cavities. A guiding component is provided at one end of the partition close to the pushing component.

[0015] By adopting the above technical solution, by dividing the material collecting box into two or more material receiving cavities through the partition, the storage capacity of the material collecting box can be improved. By providing a guiding component, the button batteries entering the material collecting box can be guided, so that the button batteries are neatly arranged in the material collecting box, thereby improving the space utilization rate in the material collecting box.

[0016] In a specific feasible implementation, the guiding component includes a rotating block and a guiding plate. The rotating block is rotatably connected to the inner bottom wall of the material collecting box. The rotating block includes a rotatable part and a guiding part integrally formed. The rotatable part is a semi-cylindrical block, and the guiding part is a triangular block. The guiding plate is fixed on one side of the rotating block close to the partition. Both ends of the guiding plate extend into the material receiving cavity, and both ends of the guiding plate away from the rotating block are inclined toward the side away from the partition.

[0017] By adopting the above technical solution, when the button battery enters the material collecting box, the button battery contacts the guiding plate, and the guiding plate drives the rotating block to deflect. Thus, when the next button battery enters the material collecting box, it can enter the other material receiving cavity along the side wall of the guiding part, so that the number of button batteries in each material receiving cavity is balanced, which is convenient for the storage and recycling of button batteries.

[0018] In a specific feasible implementation, a limiting component for limiting the button batteries is provided in the material collecting box.

[0019] By adopting the above technical solution, by using the limiting component to limit the button batteries in the material collecting box, the impact and stacking between the button batteries can be prevented, and the wear between the button batteries can be reduced, thereby facilitating the storage and recycling of unqualified button batteries.

[0020] In a specific feasible implementation, the limiting component includes a limiting plate and a spring. The limiting plate is rotatably connected to the inner wall of the material receiving cavity. One end of the spring is connected to the inner wall of the material receiving cavity, and the other end is connected to the limiting plate.

[0021] By adopting the above technical solution, by setting a limit plate and a spring, the button battery applies pressure to the limit plate when entering the material receiving box, and the limit plate applies pressure to the spring, and the spring contracts. Therefore, when the button battery enters the material receiving box, the limit plate can buffer the button battery, and can reduce the impact force between the limit plate and the end of the material receiving box away from the material guide plate, thereby protecting the button battery.

[0022] In a specific feasible implementation scheme, the limiting assembly also includes a rotating plate, a rotating rod and a cross plate. A material receiving groove is opened on the inner wall of the material receiving cavity. A rotating shaft is provided in the material receiving groove. The rotating shaft passes through the rotating plate. The rotating rod is arranged at the bottom end of the rotating plate. The rotating rod is inclined toward the side wall on one side of the partition. The cross plate is arranged at the top end of the rotating plate. The cross plate is used to separate two adjacent button batteries.

[0023] By adopting the above technical solution, the button battery applies pressure to the limit plate, and the limit plate applies pressure to the rotating rod, so that the rotating plate rotates around the rotating axis, and the horizontal plate moves toward the side close to the receiving chamber. After the next button battery enters the receiving chamber, the horizontal plate can block the two adjacent button batteries, try to avoid collisions between the button batteries, protect the button batteries, and facilitate the recycling of the button batteries.

[0024] In a specific embodiment, the thickness of the material receiving box is greater than one times the thickness of the button battery and less than two times the thickness of the button battery.

[0025] By adopting the above technical solution, since the thickness of the receiving box is greater than one times the thickness of the button batteries and less than two times the thickness of the button batteries, the button batteries will not be stacked in the receiving box, which can avoid the collision and wear of the button batteries with each other and ensure the quality of the recycled button batteries.

[0026] In summary, the present application includes at least one of the following beneficial technical effects:

[0027] 1. Button batteries can be pushed into different receiving components in turn according to the reasons for failure, and the failed button batteries can be collected separately, so as to avoid the unified collection of a large number of button batteries and avoid the stacking and wear of button batteries as much as possible;

[0028] 2. The guide assembly allows the next button battery to enter the receiving box along the side wall of the guide portion and enter a different receiving cavity with the previous button battery, so that the number of button batteries in each receiving cavity remains balanced, which is convenient for the storage and recycling of button batteries;

[0029] 3. The horizontal plate can block two adjacent button batteries, minimizing the mutual collision between button batteries and protecting the button batteries. Brief Description of the Drawings

The rotating motor 21 is fixed on the workbench 1, and the rotating disk 22 is fixed on the output shaft of the rotating motor 21. The rotating motor 21 can drive the rotating disk 22 to rotate.

[0039] Referring to Figure 1 and Figure 2, an installation groove 23 is formed on the top wall of the rotating disk 22. The installation groove 23 is annular. A positioning plate 24 is fixed in the installation groove 23. A positioning groove 25 is formed on the positioning plate 24. The side wall of the rotating disk 22 facing the positioning groove 25 is an arc surface. A plurality of limiting blocks 26 arranged at intervals along the axis of the rotating disk 22 are fixed on the top wall of the rotating disk 22. The side wall of the limiting block 26 facing the positioning groove 25 is an arc surface. A positioning cavity 27 for positioning the button battery is formed between the positioning plate 24 and the two limiting blocks 26. After the button battery enters the positioning cavity 27, the rotating motor 21 drives the rotating disk 22 to rotate, and the rotating disk 22 drives the button battery to rotate.

[0040] Referring to Figure 1 and Figure 2 , a plurality of groups of detection components 3 arranged at intervals along the circumferential direction of the rotating disk 22 are fixed on the workbench 1. The detection components 3 are respectively used to detect the appearance, thickness and power of the button battery. A limiting ring 31 is fixed on the workbench 1. The limiting ring 31 is arranged on the outer edge of the rotating disk 22. A fixing ring 32 is fixed on the limiting ring 31. A mounting rod 33 is fixed on the fixing ring 32. A mounting block 34 is fixed on the mounting rod 33. A plurality of groups of pushing components 4 are mounted on the mounting block 34. A receiving component 5 is fixed on the side wall of the limiting ring 31. The pushing components 4 and the receiving components 5 are in one-to-one correspondence. The pushing components 4 are used to push the button battery into the receiving components 5. The receiving components 5 are respectively used to receive the button batteries with unqualified appearance, unqualified thickness and unqualified power.

[0041] Referring to Figure 2 and Figure 3 , a connecting plate 40 is fixed on the fixing ring 32. The pushing component 4 includes a pushing cylinder 41, a pushing rod 42 and a pushing plate 43. The pushing cylinder 41 is fixed on the mounting block 34 and is arranged facing the connecting plate 40. A transition plate 44 is fixed on the piston rod of the pushing cylinder 41. The pushing plate 43 is fixed on the side wall of the transition plate 44 facing the connecting plate 40. The surface of the pushing plate 43 facing the connecting plate 40 is a concave arc surface, which can adapt to the shape of the button battery, increase the contact area with the button battery, and facilitate pushing the button battery. One end of the pushing rod 42 is hinged on the pushing plate 43, and the other end is hinged with a baffle plate 45. A slider 46 is fixed on the side wall of the baffle plate 45 facing the connecting plate 40. A slide rail 47 is fixed on the side wall of the connecting plate 40 facing the baffle plate 45. The slider 46 is slidably mounted on the slide rail 47. The baffle plate 45 is arranged between the positioning groove 25 and the receiving component 5. A baffle groove 48 for the baffle plate 45 to pass through is formed on the fixing ring 32.

[0042] Referring to Figure 1 and Figure 3When the detection component 3 detects an unqualified button battery, the rotating component 2 drives the unqualified button battery to rotate to the push component 4. The piston rod of the push cylinder 41 extends, driving the push plate 43 to push the button battery out of the positioning groove 25, and at the same time, the push rod 42 drives the baffle plate 45 to move upward along the slide rail 47, so that the push plate 43 can push the button battery into the receiving component 5. After the unqualified button battery is removed, the piston rod of the push cylinder 41 contracts, driving the baffle plate 45 to move downward, and the baffle plate 45 forms a barrier between the positioning cavity 27 and the receiving component 5 to prevent qualified button batteries from falling into the receiving component 5.

[0043] Reference Figure 1 and Figure 2 The limiting ring 31 is provided with a plurality of guide grooves 28 arranged circumferentially around the axis of the limiting ring 31. A guide plate 29 is fixed in the guide groove 28. The guide plate 29 is used to connect the positioning cavity 27 with the receiving assembly 5, so that unqualified button batteries can enter the receiving box 51. The receiving assembly 5 includes a receiving box 51 and a receiving plate 52. The receiving box 51 is fixed on the outer wall of the limiting ring 31. The receiving plate 52 is hinged to the receiving box 51 through a hinge. The receiving plate 52 can block the button batteries in the receiving box 51 and prevent the button batteries from falling out of the receiving box 51.

[0044] Reference Figure 4 In order to increase the storage capacity of the material receiving box 51, the width of the material receiving box 51 is set to be greater than twice the diameter of the button battery. That is, several rows of button batteries can be stored in one material receiving box 51, which can avoid stacking of multiple button batteries in the thickness direction, thereby causing wear and tear between each other. More than one partition 53 is fixed in the material receiving box 51, specifically one in this embodiment. The partition 53 is arranged in the middle of the material receiving box 51 and along the length direction of the material receiving box 51. The partition 53 divides the material receiving box 51 into two material receiving chambers 54. A guide assembly 6 is provided at one end of the partition 53 close to the pushing assembly 4. The guide assembly 6 includes a rotating block 61 and a guide plate 62. The rotating block 61 is rotatably connected to the inner bottom wall of the material receiving box 51. The rotating block 61 includes an integrally formed rotating portion 63 and a guiding portion 64. The rotating portion 63 is a semi-cylindrical block, and the guiding portion 64 is an acute triangle block. The guide plate 62 is fixed to a side of the rotating block 61 close to the partition 53 , and both ends of the guide plate 62 extend into the material receiving cavity 54 , and both ends of the guide plate 62 away from the rotating block 61 are inclined toward the side away from the partition 53 .

[0045] Reference Figure 4In the initial state, the rotating block 61 is tilted toward one side. When an unqualified button battery enters the receiving box 51, the button battery enters the receiving cavity 54 on one side along the inclined surface of the guide portion 64. The button battery applies a downward force to the guide plate 62, thereby driving the rotating block 61 to deflect, and the guide portion 64 tilts toward the other side, so that the next button battery entering the receiving box 51 can enter the receiving cavity 54 on the other side. The button batteries can be arranged neatly in the receiving cavity 54, and the stacking or misalignment of multiple button batteries can be avoided as much as possible, and the storage rate of the receiving box 51 can also be improved.

[0046] Reference Figure 4 and Figure 5 , a receiving groove 65 is provided on the inner wall of the receiving cavity 54, and a limiting assembly 7 for limiting the button battery is provided in the receiving groove 65, and the limiting assembly 7 includes a limiting plate 71 and a spring 72, the limiting plate 71 is hinged on the inner wall of the receiving cavity 54, one end of the spring 72 is fixedly connected to the inner wall of the receiving cavity 54, and the other end is fixedly connected to the limiting plate 71. The limiting assembly 7 also includes a rotating plate 73, a rotating rod 74 and a horizontal plate 75, a rotating shaft is rotatably connected in the receiving groove 65, the rotating plate 73 is fixed on the rotating shaft, the rotating rod 74 is fixed at the bottom end of the rotating plate 73, and the rotating rod 74 is inclined toward the side wall on one side of the partition 53. The horizontal plate 75 is fixed at the top of the rotating plate 73, and the horizontal plate 75 is used to separate two adjacent button batteries. When the rotating plate 73 is in a vertical state, the horizontal plate 75 will not block the button battery.

[0047] Reference Figure 4 and Figure 5 , the unqualified button battery enters the receiving chamber 54, and the unqualified button battery applies pressure to the limit plate 71 during the descent process, causing the spring 72 to contract, and the limit plate 71 pushes the rotating plate 73 to the side away from the receiving chamber 54, and the rotating plate 73 rotates around the rotating axis to move the horizontal plate 75 toward the side close to the receiving chamber 54, so that when the next unqualified button battery enters the receiving chamber 54, the horizontal plate 75 acts as a barrier between the two adjacent unqualified button batteries, which can minimize the collision between the two adjacent unqualified button batteries, protect the unqualified button batteries, and facilitate the recycling of unqualified button batteries.

[0048] The implementation principle of the embodiments of this application is as follows: After the button battery enters the positioning cavity 27, the rotating motor 21 drives the rotating disk 22 to rotate, and the rotating disk 22 drives the button battery to rotate, so that the button battery passes through multiple detection components 3 in sequence to detect the appearance, thickness and power of the button battery. After the detection is completed, the rotating disk 22 continues to drive the button battery to rotate, and several groups of pushing components 4 respectively push the button batteries with unqualified appearance, unqualified thickness and unqualified power into different material receiving components 5 to separately store the button batteries with different unqualified reasons. After the button battery is pushed into the material receiving box 51, under the guiding action of the rotating block 61, the button battery enters the material receiving cavities 54 on both sides in sequence. When the button battery enters the material receiving cavity 54, it exerts pressure on the limiting plate 71, and the limiting plate 71 compresses the spring 72 and at the same time pushes the rotating rod 74, so that the cross plate 75 moves towards the side close to the material receiving cavity 54, so that the cross plate 75 can limit the next button battery and block adjacent two button batteries, and try to avoid collision between adjacent two button batteries.

[0049] The above are all the preferred embodiments of this application. Without restricting the protection scope of this application accordingly, therefore: All equivalent changes made according to the structure, shape and principle of this application shall be covered within the protection scope of this application.
