Description

Technical Field

[0001] This invention relates to battery processing equipment, and more particularly to an automatic detection device for alkaline batteries entering the loop. Background Technology

[0002] After the positive electrode ring of an alkaline battery is inserted into the steel casing, assembly errors may occasionally result in rings that are too high, broken, or missing. Due to the randomness of these occurrences, manual sampling is typically used for inspection during downtime to save costs. However, in practice, manual sampling is not only time-consuming and labor-intensive but also carries a significant risk of missed inspections. As battery production line speeds increase, if it is not possible to detect the insertion height ( / or total battery height) of each battery online and promptly eliminate defective products, a large number of defective products will flow into the next process, causing significant battery quality problems or substantial economic losses for the company. Therefore, there is an urgent need to develop a device that can automatically detect the insertion quality of the positive electrode ring. Summary of the Invention

[0003] The purpose of this invention is to provide an automatic detection device for alkaline batteries entering the loop.

[0004] The technical solution to achieve the objective of this invention is: an automatic detection device for alkaline battery insertion, comprising an upper turntable and a lower turntable coaxially arranged from top to bottom. The upper and lower turntables are rotatably mounted on a main shaft. A steel shell seat is coaxially arranged on the upper surface of the upper turntable. The diameter of the steel shell seat is not greater than the diameter of the upper turntable. Several steel shell slots for accommodating upright steel shells are circumferentially formed along the outer edge of the steel shell seat. An upper push rod hole is formed on the upper turntable at a position directly opposite to the lower position of the steel shell slots. The diameter of the upper push rod hole is smaller than the inner diameter of the steel shell. A lower push rod hole is formed on the lower turntable, coaxial with and corresponding to each of the upper push rod holes. A push rod is movably inserted into the lower push rod hole. The diameter of the upper end of the push rod is smaller than the inner diameter of the steel shell but larger than the inner diameter of the positive electrode ring inside the steel shell. A guide is installed below the push rod. The upper turntable has a feed end and a discharge end. A detection mechanism and a rejection mechanism for removing defective steel shells are sequentially arranged on the outer side of the upper turntable between the feed end and the discharge end, along the rotation direction of the upper turntable. The detection mechanism includes a first sensor for detecting the position of the steel shell and a second sensor for detecting the position of the top of the steel shell. The highest point of the feed rod's undulation is located at the sensing point of the second sensor. The highest point of the upper end of the feed rod's undulation is limited to the point where the upper end of the feed rod is embedded in the steel shell and can lift up a qualified steel shell. The first sensor, the second sensor, the drive mechanism for driving the rotation of the main shaft, and the rejection mechanism are all communicatively connected to the control system.

[0005] Furthermore, the steel shell slot is magnetic, and a pressure plate mechanism is installed between the feed end and the detection mechanism. The pressure plate mechanism includes a pressure plate, which is located above the rotation path of the steel shell on the upper turntable. The middle part of the pressure plate is hinged to the pressure plate bracket. A tension spring is installed at one end of the pressure plate near the feed end. One end of the tension spring is fixed to the pressure plate, and the other end of the tension spring is fixed to the compression spring support. The distance between the pressure plate and the upper surface of the upper turntable is limited so that the top rod can be embedded in the steel shell at the highest point.

[0006] Furthermore, the side wall of the cam disk is provided with a groove along the circumference of the cam disk to guide the push rod to move up and down, and a roller is fixedly installed on the side of the bottom of the push rod by a pin, and the roller is movably embedded in the groove.

[0007] Furthermore, a bushing is fitted onto the push rod.

[0008] Furthermore, the rejection mechanism includes a rejection cylinder and a push plate. The rejection cylinder is mounted on a cylinder seat located above the upper turntable. The free end of the piston rod of the rejection cylinder faces the outer edge of the upper turntable. The push plate is mounted on the free end of the piston rod of the rejection cylinder.

[0009] Furthermore, the push plate has an arc-shaped notch, which faces the side of the steel shell after passing through the rejection mechanism. The arc-shaped notch increases the contact area between the steel shell and the push plate during material pushing, thereby improving the stability of material pushing.

[0010] Furthermore, the compression spring support is fixed to the pressure plate bracket.

[0011] Furthermore, a protective plate is installed adjacent to the outer side of the upper turntable to prevent the steel shell from falling off. The protective plate is arranged between the feeding end and the rejection mechanism along the trajectory of the steel shell entering and exiting the material.

[0012] Furthermore, both the detection mechanism and the pressure plate bracket are installed on the upper surface of the protective plate.

[0013] The alkaline battery insertion automatic detection device of this invention utilizes a push rod that follows the undulating curve of the cam disk to embed itself into the steel shell and lift the steel shell. A second sensor records the position of the top of the steel shell below it and sends the data to the control system. The control system determines whether the insertion height of the battery is within the process range according to the programmed benchmark, thereby identifying batteries with poor insertion. A rejection mechanism then removes the batteries with poor insertion from the upper turntable. Its compact structure improves the rejection efficiency of batteries with poor insertion.

[0018] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings:

[0019] like Figures 1 to 4 As shown, an automatic detection device for alkaline battery insertion includes an upper turntable 1 and a lower turntable 2 coaxially arranged from top to bottom. The upper turntable 1 and the lower turntable 2 are rotatably mounted on a main shaft 4. A steel shell seat 12 is coaxially arranged on the upper surface 11 of the upper turntable 1. The diameter of the steel shell seat 12 is smaller than the diameter of the upper turntable 1. Several steel shell slots 121 for accommodating upright steel shells 10 are circumferentially formed on the outer edge of the steel shell seat 12. The steel shell slots 121 are magnetic. An upper push rod hole 13 is formed on the upper turntable 1 at the position directly below the steel shell slots 121. The diameter of the upper push rod hole 13 is smaller than the inner diameter of the steel shell 10. The lower turntable... The upper part 2 has a lower push rod hole 21 that is coaxial with and corresponds one-to-one with each of the upper push rod holes 12. A push rod 5 with a bushing 22 is coaxially and movably inserted in the lower push rod hole 21. The diameter D of the upper end 51 of the push rod 5 is smaller than the inner diameter A of the steel shell 10 and larger than the inner diameter B of the positive electrode ring in the steel shell 10. A cam disk 6 is installed below the push rod 5. The cam disk 6 is coaxially fixed with the main shaft 4. The side wall of the cam disk has a groove 61 along the circumference of the cam disk to guide the push rod 5 to make undulating movements. A roller 54 is fixedly installed on the side of the bottom 52 of the push rod 5 by a pin 53. The roller 54 is movably embedded in the groove 61.

[0020] The upper turntable 1 has a feeding end 14 and a discharging end 15. A pressure plate mechanism 7, a detection mechanism 8, and a rejection mechanism 9 are sequentially arranged on the outer side of the upper turntable 1 between the feeding end 14 and the discharging end 15 along the rotation direction of the upper turntable. A protective plate 16 is installed adjacent to the outer side of the upper turntable 1 to prevent the steel shell from falling off. The protective plate 16 is arranged between the feeding end 14 and the rejection mechanism 9 along the trajectory of the steel shell entering and exiting the material.

[0021] The pressure plate mechanism 7 includes a pressure plate 71, which is located above the rotation path of the steel shell 10 on the upper turntable 1. The middle part of the pressure plate 71 is hinged to the pressure plate bracket 72. A tension spring 73 is installed at one end of the pressure plate 71 near the feed end 13. A tension spring support 74 is installed on the pressure plate bracket 72. One end of the tension spring 73 is fixed to the pressure plate 71, and the other end of the tension spring 73 is fixed to the spring support 74. The distance between the pressure plate 71 and the upper surface 11 of the upper turntable 1 is the height of the steel shell 10.

[0022] The detection mechanism 8 includes a first sensor 81 for detecting the position of the steel shell and a second sensor 82 for detecting the top position of the steel shell. The highest point of the upper end 51 of the push rod is located at the sensing point of the second sensor 82. The highest point of the upper end 51 of the push rod is limited to the point where the push rod is embedded in the steel shell 10 and can lift the steel shell 10.

[0023] The rejection mechanism 9 includes a rejection cylinder 91 and a push plate 92. The rejection cylinder 91 is mounted on a cylinder seat 93 located above the upper turntable 1. The free end of the piston rod 911 of the rejection cylinder 91 faces the outer edge of the upper turntable 1. The push plate 92 is mounted on the free end of the piston rod 911 of the rejection cylinder 91. The push plate 92 has an arc-shaped notch 921, which is opposite to the side of the steel shell 10 passing through the rejection mechanism 9. The first sensor 81, the second sensor 82, the drive mechanism (not shown) that drives the main shaft 4 to rotate, and the rejection mechanism 9 are all communicatively connected to the control system (not shown).

[0024] The working principle of the automatic alkaline battery insertion detection device implemented in this embodiment is as follows:

[0025] 1. The steel shell with the positive electrode ring is conveyed downwards by the conveying equipment and fed one by one from the feed end into the steel shell slot. When the steel shell rotates with the upper turntable and passes under the pressure plate, some qualified steel shells that are of different heights due to the deviation of the adsorption position of the steel shell during feeding can be adjusted to have a uniform height.

[0026] 2. The steel shell continues to rotate with the upper turntable to the position of the detection device. At the same time, the push rod is embedded in the steel shell along the undulating curve of the cam plate and lifts the steel shell. At this time, the first sensor senses the steel shell and sends a signal to the control system. The control system sends a command to the second sensor. The second sensor detects the distance between the top position of the steel shell below it and the second sensor, and sends the data to the control system. The control system determines whether the battery's ring insertion height is within the process range according to the benchmark designed in the program. If the distance is greater than the set value, there is a missing ring. If the distance is less than the set value, the ring height exceeds the standard. In this way, steel shells with poor ring insertion are identified.

[0027] 3. For steel shells with poor entry into the ring, the upper turntable continues to rotate to the position of the rejection mechanism. The rejection cylinder receives a command from the control system, and the piston rod of the rejection cylinder extends, using a push plate to push the steel shell with poor entry into the ring out of the upper turntable.

[0028] The steel shell slot of the present invention can be fitted with a magnet with a certain magnetic properties as needed to fix the steel shell in the slot, thereby improving the stability of the steel shell as it rotates with the upper turntable.

[0029] The upper and lower turntables are rotatably mounted on the main shaft via bearings, which is a conventional technical method in the mechanical field and will not be described in detail here.

[0030] The pressure plate is used to limit the height of the steel shell. The distance between the pressure plate and the upper surface of the upper turntable can be the same as the height of the steel shell or slightly greater than the height of the steel shell, as long as the top rod can be embedded in the steel shell at the highest point and lift the normal steel shell.

[0031] The rejection mechanism structure is not limited to that shown in the embodiment. Air blowing rejection can also be used, but the structure of the embodiment is simpler and more reliable. The arc-shaped notch of the push plate can increase the contact surface between the steel shell and the push plate when pushing the material, thereby improving the stability of pushing the material.

[0032] The protective plate is provided as needed to increase the stability of the steel shell as it rotates with the upper turntable.

[0033] The bushing is provided as needed to guide the movement of the push rod.

[0034] The roller located on the side of the push rod replaces the bottom of the push rod and slides in connection with the cam disk, resulting in a more compact structure.

[0035] The second sensor is a commercially available fiber optic coaxial displacement sensor. The drive mechanism that drives the main shaft to rotate is a conventional technical means in the mechanical field and will not be described in detail here. The conveying device that conveys the steel shell into and out of the upper turntable can be the battery turntable transition structure disclosed in CN201920603613.2 and will not be described in detail here.

[0036] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent process transformations made using the content of the present invention specification, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present invention.
