Description

Technical Field

[0001] The invention relates to the technical field of battery production equipment, and in particular to a detection device for a button-type battery negative electrode cover embedded plastic part. Background Art

[0002] With the rapid development of electronic technology, various electrical equipment on the market are gradually becoming miniaturized, and button batteries have been widely used as power sources for portable electronic devices. Button batteries are composed of interlocking positive and negative electrode covers and their internal electrolytes. A sealing plastic ring is provided between the interlocking positive and negative electrode covers. The sealing plastic ring insulates the positive and negative electrode covers on the one hand, and on the other hand, it can form a sealed space inside the interlocking positive and negative electrode covers to prevent leakage of the electrolyte inside the interlocking positive and negative electrode covers. The sealing plastic ring is made of nylon material. Specifically, it is made of nylon material that is first injected onto the inner and outer peripheral walls of the negative electrode cover through an injection molding process. Figure 1 The structure of the sealing plastic ring of the negative electrode cover of a button-type battery is shown. Since the quality of the sealing plastic ring seriously affects the quality of the final button battery, if the sealing plastic ring is not fully injected, it is easy to cause the risk of leakage or weight loss. If the sealing plastic ring overflows with glue, the space inside the negative electrode cover is occupied by glue, and there are problems such as non-stick lithium in the next process. Therefore, it is necessary to detect the quality of the sealing plastic ring injected on the negative electrode cover. However, nylon material is a transparent material. The quality of the sealing plastic ring formed after the nylon material is injected into the negative electrode cover cannot be effectively detected by vision, that is, conventional visual inspection cannot effectively and quickly distinguish defective products such as incomplete injection or overflow of glue. Therefore, in the existing button battery production, the quality of the sealing plastic ring on the negative electrode cover is mostly not inspected, or a rough inspection is performed by vision, and the inspection efficiency is low and the effect is poor. Summary of the invention

[0003] The object of the present invention is to provide a detection device for a button-type battery negative electrode cover molded part.

[0004] The technical scheme for realizing the purpose of the present invention is: a detection device for button-type battery negative electrode cover plastic inserts, comprising a detection mechanism and a control system, wherein the detection mechanism is used to detect the quality of the sealing plastic insert ring on any one of the inner peripheral wall and the outer peripheral wall of the button-type battery negative electrode cover, the detection mechanism comprises a turntable, and an in-place sensing device, a light source, a camera device, a gas nozzle device and a dial plate fixed on a frame and located above the turntable, the in-place sensing device, the light source and the camera device are arranged in sequence from bottom to top, the light source is an annular light source, the gas path sprayed by the gas nozzle device is horizontally arranged close to the surface of the turntable, the dial plate is located on the conveying path of the button-type battery negative electrode cover with normal sealing plastic insert ring quality on the turntable, but not on the gas path sprayed by the gas nozzle device, the in-place sensing device, the camera device and the gas nozzle device are all communicatively connected with the control system, wherein the in-place sensing device detects the in-place information of the button-type battery negative electrode cover on the turntable, and sends the in-place information of the button-type battery negative electrode cover to the control system; the control system receives the in-place information of the button-type battery negative electrode cover transmitted by the in-place sensing device, and controls the button-type battery negative electrode cover according to the in-place sensing device. The control signal is sent to the camera device based on the information of the negative electrode cover of the button battery in place, so as to control the camera device to take a picture of the button battery negative electrode cover that is rotated with the turntable to be located directly below the light source, so that the button battery negative electrode cover and the sealing plastic ring on the inner peripheral wall or the outer peripheral wall form a distinguishable image, and, based on the pictures taken by the camera device, the quality of the sealing plastic ring injected on the button battery negative electrode cover is analyzed and judged. If the quality of the sealing plastic ring injected on the button battery negative electrode cover does not meet the standards, a control signal is sent to the gas nozzle device to make the gas nozzle device spray gas , the button battery negative electrode cover with the sealing plastic ring injected thereon that does not meet the quality standards is blown out of the turntable. During inspection, the button battery negative electrode cover is placed on the turntable and moves with the turntable. When the inspection mechanism is used to inspect the quality of the sealing plastic ring on the inner circumferential wall of the button battery negative electrode cover, the light source is a blue light source, and the button battery negative electrode cover is located on the turntable with the cover facing upward. When the inspection mechanism is used to inspect the quality of the sealing plastic ring on the outer circumferential wall of the button battery negative electrode cover, the light source is either a blue light source or a white light source, and the button battery negative electrode cover is located on the turntable with the cover facing downward.

[0005] Furthermore, the position sensing device includes a light emitting element and a light detecting element located on the optical path of the light emitting element, and the light detecting element is communicatively connected with the control system. In this arrangement, when working, the light detecting element of the position sensing device detects the light signal emitted by the light emitting element, and converts the light signal into an electrical signal and sends it to the control system. The control system receives the electrical signal sent by the light detecting element of the position sensing device, and determines whether to send a control signal to the camera device based on the electrical signal to control the camera device to take a picture of the negative electrode cover of the button battery that rotates with the turntable to be located directly below the light source. In the present invention, the position sensing device can also be a proximity sensor. Compared with a proximity sensor with poor sensitivity, it is preferable that the position sensing device of the present invention adopts a photoelectric sensor, that is, the position sensing device includes a light emitting element and a light detecting element located on the optical path of the light emitting element.

[0006] Furthermore, a waste collection box is provided on one side of the turntable, which is located on the horizontal projection of the gas path ejected by the gas nozzle device. The waste collection box can be conveniently used to collect the button cell negative electrode caps that are not up to standard and are ejected from the turntable by the gas nozzle device.

[0007] Furthermore, the button-type battery negative electrode cover molded parts detection device also includes a feeding conveyor belt and a first feeding gear, the feeding conveyor belt is close to a turntable of a detection mechanism, the first feeding gear is driven by a first power mechanism and can be rotatably installed on the frame, and the first feeding gear is horizontally arranged and straddles the adjacent feeding conveyor belt and turntable. During operation, the button-type battery negative electrode cover is on the feeding conveyor belt, and when it is transported to the first feeding gear by the feeding conveyor belt, it enters the tooth groove of the first feeding gear and is brought to the corresponding turntable of the detection mechanism by the rotating first feeding gear. In the present invention, the button-type battery negative electrode cover can be manually placed on the turntable of the detection mechanism, or the button-type battery negative electrode cover can be placed on the turntable of the detection mechanism by the above-mentioned feeding conveyor belt and the first feeding gear, or by other manipulators such as suction cups. However, compared with other feeding methods, the feeding setting of the feeding conveyor belt and the first feeding gear has a simpler structure, a faster feeding speed, and a higher degree of automation.

[0008] Furthermore, when the detection mechanism is used to detect the quality of the sealing plastic ring on the inner circumference of the button-type battery negative electrode cover, there are three camera devices, one of which is vertically arranged, and the other two camera devices are symmetrically distributed inwardly on both sides of the vertically arranged camera device. In actual production, "overflowing glue" and "incomplete injection molding" of the sealing plastic ring on the inner circumference of the button-type battery negative electrode cover will cause the quality of the sealing plastic ring on the inner circumference of the button-type battery negative electrode cover to be substandard. When inspecting the quality of the sealing plastic ring on the inner circumference of the negative electrode cover of a button-type battery, the number of the camera devices of the present invention may be one, two or more. Regardless of the number of the camera devices, the image formed by the camera device on the negative electrode cover of the button-type battery directly below can more or less reflect the condition of the sealing plastic ring on the inner circumference of the negative electrode cover of the button-type battery, but it may not be able to fully and clearly reflect the condition of the sealing plastic ring on the inner circumference of the negative electrode cover of the button-type battery. For example, a vertically arranged camera device forms an image of the negative electrode cover of the button-type battery directly below it. Since the inner circumference of the negative electrode cover of the button-type battery is concave, it can only clearly image the bottom surface inside the negative electrode cover of the button-type battery and the sealing plastic ring overflowing on the bottom surface, but cannot fully and clearly image the condition of the sealing plastic ring on the inner circumference of the negative electrode cover of the button-type battery. That is to say, a vertically arranged camera device can only clearly reflect whether the sealing plastic ring on the inner circumference of the button type battery negative electrode cover has overflowed glue to the bottom surface inside the button type battery negative electrode cover, but cannot clearly reflect whether the sealing plastic ring on the inner circumference of the button type battery negative electrode cover is not fully injected. Therefore, when the detection mechanism is used to detect the quality of the sealing plastic ring on the inner circumference of the button type battery negative electrode cover, if only one vertically arranged camera device is provided, it can only detect defective products with "overflowing glue" of the sealing plastic ring on the inner circumference of the button type battery negative electrode cover, but cannot detect defective products with "incomplete injection" of the sealing plastic ring on the inner circumference of the button type battery negative electrode cover, and the detection rate of defective products is relatively low. In order to detect defective products whose quality of the sealing plastic ring on the inner wall of the negative electrode cover of button type batteries does not meet the quality standards 100% without installing too many camera devices, preferably, when the detection mechanism is used to detect the quality of the sealing plastic ring on the inner wall of the negative electrode cover of button type batteries, there are three camera devices, one of which is vertically arranged, and the other two camera devices are symmetrically distributed inwardly on both sides of the vertically arranged camera device. Under this preferred mode, the middle camera device can clearly reflect whether the sealing plastic ring on the inner circumference of the button battery's negative electrode cover has overflowed glue toward the bottom surface of the button battery's negative electrode cover, thereby detecting defective products with "overflowing glue" from the sealing plastic ring on the inner circumference of the button battery's negative electrode cover; the cameras arranged inwardly on both sides can clearly image the sealing plastic ring on the circumference of the button battery's negative electrode cover, clearly reflect whether the sealing plastic ring on the inner circumference of the button battery's negative electrode cover is not fully injected, thereby detecting defective products with "incomplete injection" of the sealing plastic ring on the inner circumference of the button battery's negative electrode cover.

[0009] Furthermore, when the detection mechanism is used to detect the quality of the sealing plastic ring on the outer peripheral wall of the button-type battery negative electrode cover, the light source is a white light source. Since the blue light source is more harmful to human eyes, it is better to use a white light source when the detection mechanism of the present invention detects the quality of the sealing plastic ring on the outer peripheral wall of the button-type battery negative electrode cover.

[0010] Furthermore, when the detection mechanism is used to detect the quality of the sealing plastic ring on the outer peripheral wall of the button-type battery negative electrode cover, a coaxial light source with the same color as the light source is also provided on the frame. The setting of the vertically irradiated coaxial light source improves the uniformity of illumination, and after the camera device takes a picture of the button-type battery negative electrode cover under the light source, it can enhance the contrast of the image formed by the button-type battery negative electrode cover and the sealing plastic ring on the outer peripheral wall, so as to more clearly reflect the condition of the sealing plastic ring on the outer peripheral wall of the button-type battery negative electrode cover.

[0011] Furthermore, when the detection mechanism is used to detect the quality of the sealing plastic ring on the outer peripheral wall of the button battery negative electrode cover, the number of the camera device is one, and it is vertically arranged. When the sealing plastic ring is injected onto the button battery negative electrode cover, the button battery negative electrode cover is installed in the fixing seat and is integrated with the fixing seat. During the injection molding process, the sealing plastic ring on the outer peripheral wall of the button battery negative electrode cover will not overflow onto the outer surface. Therefore, the "incomplete injection molding" of the sealing plastic ring on the outer peripheral wall of the button battery negative electrode cover is the main factor causing the quality of the sealing plastic ring on the outer peripheral wall of the button battery negative electrode cover to be substandard. When inspecting the quality of the sealing plastic ring on the outer peripheral wall of the button-type battery negative electrode cover, the number of the camera devices of the present invention can be one, two or more. Regardless of the number of the camera devices, the image formed by the camera device on the button-type battery negative electrode cover directly below can more or less reflect the condition of the sealing plastic ring on the outer peripheral wall of the button-type battery negative electrode cover, but it may not be able to fully and clearly reflect the condition of the sealing plastic ring on the inner peripheral wall of the button-type battery negative electrode cover. For example, if a camera device is set up tilted to take a picture of the button-type battery negative electrode cover directly below it, the picture taken can only show the condition of the sealing plastic ring on the outer peripheral wall of the button-type battery negative electrode cover. The portion of the sealing plastic ring under one viewing angle cannot fully display the sealing plastic ring on the outer peripheral wall of the button-type battery negative electrode cover. Therefore, an inclined camera device can only reflect whether the portion of the sealing plastic ring on the outer peripheral wall of the button-type battery negative electrode cover shown in the photo is not fully injected, but cannot reflect whether the sealing plastic ring on the outer peripheral wall of the button-type battery negative electrode cover is not fully injected. In other words, for defective products in which the portion of the sealing plastic ring shown in the photo is fully injected and the portion of the sealing plastic ring not photographed is not fully injected, it cannot be detected, and the detection rate of defective products is relatively low. In order to detect 100% of the defective products whose sealing plastic ring on the outer peripheral wall of the button-type battery negative electrode cover does not meet the quality standards, and at the same time, there is no need to install too many cameras, preferably, when the detection mechanism is used to detect the quality of the sealing plastic ring on the outer peripheral wall of the button-type battery negative electrode cover, the number of cameras is one, and they are set vertically. Under this preferred mode, the vertically arranged camera device can completely capture the sealing plastic ring on the outer peripheral wall of the button type battery's negative electrode cover, which can clearly reflect whether the sealing plastic ring on the outer peripheral wall of the button type battery's negative electrode cover is not fully injected, thereby detecting defective products with "incomplete injection" of the sealing plastic ring on the outer peripheral wall of the button type battery's negative electrode cover.

[0012] Furthermore, there are two detection mechanisms, and the two detection mechanism processes are connected in sequence, wherein one detection mechanism is used to detect the quality of the sealing plastic-embedded ring on the inner peripheral wall of the button-type battery negative electrode cover, and the other detection mechanism is used to detect the quality of the sealing plastic-embedded ring on the outer peripheral wall of the button-type battery negative electrode cover. The two detection mechanisms can sequentially detect the sealing plastic-embedded ring on the inner peripheral wall and the sealing plastic-embedded ring on the outer peripheral wall of the button-type battery negative electrode cover, thereby achieving continuous, rapid, and comprehensive detection of the sealing plastic-embedded ring on the button-type battery negative electrode cover.

[0013] Furthermore, the button-type battery negative electrode cover inlay molding detection device also includes a transition conveyor belt and a second feeding gear, the transition conveyor belt includes an upper conveyor belt and a lower conveyor belt which are vertically stacked and arranged in opposite conveying directions, an arc-shaped flipping guide plate is provided at the output end of the upper conveyor belt, the flipping guide plate is vertically arranged and the gap surrounds the end of the output end of the upper conveyor belt, in the vertical direction, the upper end of the flipping guide plate is higher than the upper surface of the upper conveyor belt, the lower end of the flipping guide plate is close to the upper surface of the lower conveyor belt, and the gap between the flipping guide plate and the upper conveyor belt forms a flipping of the button-type battery negative electrode cover. The channel, the upper conveyor belt is close to the position where the dial of the detection mechanism in the previous process is provided with a dial plate, and is on the dispensing path of the button type battery negative electrode cover. When working, the dial plate on the turntable of the detection mechanism in the previous process can push the normal negative electrode cover that rotates with the turntable to the dial plate position to the upper conveyor belt. One side of the output end of the lower conveyor belt is close to the turntable of the detection mechanism in the later process. The second feed gear is driven by the second power mechanism and can be rotatably installed on the frame. The second feed gear is horizontally arranged and spans the lower conveyor belt of the transition conveyor belt and the turntable of the detection mechanism in the later process. During operation, the normal button-type battery negative electrode caps on the turntable of the detection mechanism in the front process that have not been sprayed away by the gas nozzle device, when the turntable rotates to the dial plate, are pushed away from the turntable and enter the upper conveyor belt of the transition conveyor belt under the guidance of the dial plate, and are transported together with the upper conveyor belt. When they are transported to the output end of the upper conveyor belt, they enter the flip channel. The button-type battery negative electrode caps in the flip channel are limited by the flip guide plate and are flipped vertically 180° and enter the lower conveyor belt. Then, they are transported to the second feed gear together with the lower conveyor belt, enter the tooth groove of the second feed gear, and are brought to the turntable of the detection mechanism in the back process by the rotating second feed gear. According to the present invention, the normal button-type battery negative electrode caps that have not been sprayed away by the gas nozzle device on the turntable of the detection mechanism in the previous process can be manually turned over and transferred to the turntable of the detection mechanism in the next process. The normal button-type battery negative electrode caps that have not been sprayed away by the gas nozzle device on the turntable of the detection mechanism in the previous process can also be turned over and transferred to the turntable of the detection mechanism in the next process through the settings of the above-mentioned transition conveyor belt and the second feeding gear, or other settings such as suction cup turning manipulators. Compared with other feeding methods, the turning and transferring settings of the transition conveyor belt and the second feeding gear have a simple structure, a fast feeding speed, and a higher degree of automation.

[0014] Furthermore, the detection mechanism in the previous process is used to detect the quality of the sealing plastic ring on the inner circumference of the button battery negative electrode cover, and the detection mechanism in the later process is used to detect the quality of the sealing plastic ring on the outer circumference of the button battery negative electrode cover. When detecting the quality of the sealing plastic ring on the inner circumference of the button battery negative electrode cover, the cover of the button battery negative electrode cover faces upward, and when detecting the quality of the sealing plastic ring on the outer circumference, the cover of the button battery negative electrode cover faces downward. The button battery negative electrode cover that is messy before the detection can be easily formed into a posture with the cover facing upward through shaping. In addition, the probability of unqualified quality of the sealing plastic ring on the inner circumference of the button battery negative electrode cover is higher than that of unqualified quality of the sealing plastic ring on the outer circumference. Therefore, in order to make the specified posture of the button battery negative electrode cover easier to obtain before the detection, and the defective products can be quickly detected during the detection, it is better to first detect the quality of the sealing plastic ring on the inner circumference of the button battery negative electrode cover, and then detect the quality of the sealing plastic ring on the outer circumference of the button battery negative electrode cover.

[0015] Furthermore, a qualified product collection box is provided on one side of the rotating disk of the subsequent testing mechanism, and the qualified product collection box is close to the position where the dial plate is provided on the rotating disk of the subsequent testing mechanism. During operation, when the qualified products on the rotating disk of the subsequent testing mechanism rotate with the rotating disk to the dial plate, they are pulled off the rotating disk under the guidance of the dial plate and fall into the qualified product collection box. The provision of the qualified product collection box facilitates the collection of button battery negative electrode caps that meet quality standards.

[0016] The button-type battery negative electrode cover plastic insert detection device of the present invention, when working, the button-type battery negative electrode cover is placed on a turntable of the detection mechanism and rotates with the turntable. When rotating to be close to the position sensing device, the position sensing device detects the position information of the button-type battery negative electrode cover and sends the position information of the button-type battery negative electrode cover to the control system. The control system sends a control signal to the camera device according to the position information of the button-type battery negative electrode cover, controls the camera device to take a picture of the button-type battery negative electrode cover that rotates with the turntable to be located directly below the light source, so that the button-type battery negative electrode cover and the sealing plastic insert ring on the inner peripheral wall or the outer peripheral wall form a distinguishable image, and judges the sealing plastic insert ring on the button-type battery negative electrode cover according to the picture taken by the camera device. The quality of the plastic-inlay ring. If the quality of the sealed plastic-inlay ring molded on the button-type battery negative electrode cover does not meet the standards, a control signal is sent to the gas nozzle device to make the gas nozzle device spray gas to blow the button-type battery negative electrode cover with the sealed plastic-inlay ring that does not meet the standards out of the turntable; if the quality of the sealed plastic-inlay ring molded on the button-type battery negative electrode cover meets the standards, the button-type battery negative electrode cover with the sealed plastic-inlay ring that meets the standards continues to rotate with the turntable, and when it rotates to the dial plate, it is guided by the dial plate to move out of the turntable. In this way, the quality of the sealed plastic-inlay ring of the button-type battery negative electrode cover is detected, and the button-type battery negative electrode cover with the sealed plastic-inlay ring that does not meet the standards is separated from the button-type battery negative electrode cover with the sealed plastic-inlay ring that meets the standards.The button battery negative electrode cover plastic-embedded part detection device of the present invention senses the position of the button battery negative electrode cover on the turntable through a position sensing device, so that the control system controls the camera device to take a picture of the button battery negative electrode cover under the light source, so that the button battery negative electrode cover under the light source and the sealing plastic-embedded ring on the inner peripheral wall or the outer peripheral wall form a strong contrast image, that is, the image of the sealing plastic-embedded ring on the inner peripheral wall or the outer peripheral wall of the button battery negative electrode cover can be distinguished through the photo. When the quality of the sealing plastic-embedded ring on the inner peripheral wall or the outer peripheral wall of the button battery negative electrode cover meets the standard or does not meet the standard (such as incomplete injection molding or glue overflow), the image formed is different. For example, when the quality of the sealing plastic-embedded ring on the inner peripheral wall or the outer peripheral wall of the button battery negative electrode cover meets the standard, the image formed by the sealing plastic-embedded ring on the inner peripheral wall or the outer peripheral wall of the button battery negative electrode cover is evenly distributed in an annular shape, and the inner peripheral wall or the outer peripheral wall of the button battery negative electrode cover is uniformly distributed in an annular shape. When the quality of the upper sealing plastic ring does not meet the standard, the image formed by the sealing plastic ring on the inner circumference or outer circumference of the button-type battery negative electrode cover is just the opposite, with a non-uniform annular distribution. For example, if there is a break in the image or the inner edge extends inward, the control system can quickly and effectively analyze and determine the quality of the button-type battery negative electrode cover and the sealing plastic ring on its inner circumference or outer circumference based on the photo taken by the camera device, that is, the image formed by the sealing plastic ring on the inner circumference or outer circumference of the button-type battery negative electrode cover and its inner circumference or outer circumference. At the same time, through the control system's control of the gas nozzle device, the button-type battery negative electrode cover whose inner circumference or outer circumference does not meet the quality standard of the sealing plastic ring can be timely separated, thereby realizing automatic detection of the plastic parts on the button-type battery negative electrode cover, and compared with the rough detection of artificial vision, the detection of the plastic parts on the button-type battery negative electrode cover by the present invention is more reliable and efficient.

[0028] In a preferred embodiment of the button cell negative electrode cover molded part detection device of the present invention, one side of the turntable 11 of the two detection mechanisms (1, 1') is provided with a waste collection box 17 located on the horizontal projection of the gas path sprayed by the gas nozzle device 15.

[0029] In a device for detecting plastic-embedded parts of negative electrode covers of button-type batteries under a preferred embodiment of the present invention, a detection mechanism 1 is used to detect the quality of a sealing plastic-embedded ring 2001 on the inner circumferential wall of the negative electrode cover 200 of the button-type battery. The light source 13 of the detection mechanism 1 is a blue light source. There are three camera devices 14, one of which is vertically arranged, and the other two camera devices 14 are symmetrically distributed inwardly and tilted on both sides of the vertically arranged camera device 14. During detection, the negative electrode cover of the button-type battery is located on the turntable 11 with the cover facing upward.

[0030] A detection device for a negative electrode cover of a button-type battery according to a preferred embodiment of the present invention is as follows: Figures 2 to 4 As shown, it also includes a feed conveyor belt 10 and a first feed gear 20. The feed conveyor belt 10 is close to the turntable 11 of the detection mechanism 1. The first feed gear 20 is driven by a first power mechanism 201 and can be rotatably installed on the frame 100. The first feed gear 20 is horizontally arranged and spans the adjacent feed conveyor belt 10 and the turntable 11 of the detection mechanism 1.

[0031] In a device for detecting plastic-embedded parts of negative electrode covers of button-type batteries under a preferred embodiment of the present invention, the detecting mechanism 1' is used to detect the quality of the sealing plastic-embedded ring 2002 on the outer peripheral wall of the negative electrode cover 200 of the button-type battery. A coaxial light source 130 is also provided on the frame 100 of the detecting mechanism 1'. Both the light source 13 of the detecting mechanism 1' and the coaxial light source 130 are white light sources. There is one camera device 14, which is vertically arranged. During detection, the negative electrode cover of the button-type battery is located on the turntable 11 with the cover facing downward.

[0032] A detection device for a negative electrode cover of a button-type battery according to a preferred embodiment of the present invention is as follows: Figure 2 and Figure 7As shown, it also includes a transition conveyor belt 30 and a second feeding gear 40. The transition conveyor belt 30 includes an upper conveyor belt 301 and a lower conveyor belt 302 which are vertically stacked and arranged in opposite conveying directions. The output end of the upper conveyor belt 301 is provided with an arc-shaped flip guide plate 303. The flip guide plate 303 is vertically arranged and the gap surrounds the end of the output end of the upper conveyor belt 301. In the vertical direction, the upper end of the flip guide plate 303 is higher than the upper surface of the upper conveyor belt 301, and the lower end of the flip guide plate 303 is close to the upper surface of the lower conveyor belt 302. The gap between the flip guide plate 303 and the upper conveyor belt 301 forms a flip channel 304 for the negative electrode cover of the button battery The upper conveyor belt 301 is on the removal path of the button-type battery negative electrode cover at a position where the dial 16 is provided on the turntable 11 of the detection mechanism in the previous process. When working, the dial 16 on the turntable 11 of the detection mechanism 1 can push the normal negative electrode cover that rotates to the position of the dial 16 with the turntable 11 to the upper conveyor belt 301. The output end of the lower conveyor belt 302 is close to the turntable 11 of the detection mechanism 1'. The second feed gear 40 is driven by the second power mechanism 401 and can be rotatably installed on the frame 100. The second feed gear 40 is horizontally arranged and spans the lower conveyor belt 301 of the transition conveyor belt 30 and the turntable 11 of the detection mechanism 1'.

[0033] In the button cell negative electrode cover molded parts inspection device according to the preferred embodiment of the present invention, a qualified product collection box 18 is provided on one side of the turntable 11 of the inspection mechanism 1', and the qualified product collection box 18 is close to the position where the dial 16 is provided on the turntable 11 of the inspection mechanism 1'.

[0034] According to the button-type battery negative electrode cover plastic-inserted parts detection device under the preferred embodiment of the present invention, when working, the button-type battery negative electrode cover is placed on the feeding conveyor belt 10 with the cover opening facing upward. When it is transported to the first feeding gear 20 by the feeding conveyor belt 10, it enters the tooth groove of the first feeding gear 20, and is brought to the turntable 11 of the detection mechanism 1 by the rotating first feeding gear 20. It rotates with the turntable 11 of the detection mechanism 1. When it rotates to the optical path of the light emitting element 121 of the mid-position sensing device 12 of the detection mechanism 1, the light detecting element 122 cannot detect the light signal sent by the light emitting element 121. The control system 2 controls the camera device 14 of the detection mechanism 1 to take a picture of the button-type battery negative electrode cover of the detection mechanism 1 that is rotated with the turntable 11 to be located directly below the light source 13 according to the electrical signal about this situation sent by the light detecting element 122, so that the button-type battery negative electrode cover and the sealing plastic-inserted ring on the inner circumferential wall form a distinguishable image. The control system System 2 judges the quality of the sealing plastic ring on the inner circumferential wall of the button-type battery negative electrode cover based on the photos taken by the camera device 14 of the detection mechanism 1. If the quality of the sealing plastic ring on the inner circumferential wall of the button-type battery negative electrode cover does not meet the standards, such as the sealing plastic ring on the inner circumferential wall of the button-type battery negative electrode cover is not fully injected or overflows, a control signal is sent to the gas nozzle device 15 of the detection mechanism 1 to make the gas nozzle device 15 of the detection mechanism 1 spray gas to blow the button-type battery negative electrode cover with the sealing plastic ring on the inner circumferential wall that does not meet the standards out of the turntable 11 of the detection mechanism 1 and collect it in the waste collection box 17 of the detection mechanism 1. If the quality of the sealing plastic ring on the inner circumferential wall of the button-type battery negative electrode cover meets the standards, the button-type battery negative electrode cover with the sealing plastic ring that meets the standards continues to rotate with the turntable 11 of the detection mechanism 1, and when it rotates to the dial plate 16 of the detection mechanism 1, it is guided by the dial plate 16 of the detection mechanism 1 and dialed to the upper conveyor belt 301 of the transition conveyor belt 30.The button-type battery negative electrode cap on the upper conveyor belt 301 of the transition conveyor belt 30 is driven to move by the upper conveyor belt 301, and when it moves to the output end of the upper conveyor belt 301, it enters the flip channel 304. The button-type battery negative electrode cap in the flip channel 304 is vertically flipped 180 degrees under the limit of the flip guide plate 303, and enters the lower conveyor belt 302 with the cover facing downward, and then is transported to the second feeding gear 40 together with the lower conveyor belt 302, enters the tooth groove of the second feeding gear 40, and is rotated by the first The second feeding gear 40 is brought onto the turntable 11 of the detection mechanism 1' and rotates with the turntable 11 of the detection mechanism 1'. When it rotates to the optical path of the light emitting element 121 of the sensing device 12 in the detection mechanism 1', the light detecting element 122 cannot detect the light signal sent by the light emitting element 121. The control system 2 controls the camera device 14 of the detection mechanism 1' to detect the negative electrode cover of the button battery in the detection mechanism 1' that rotates with the turntable 11 to the position directly below the light source 13 according to the electrical signal about this situation sent by the light detecting element 122. The camera 14 of the detection mechanism 1' takes pictures to form distinguishable images of the negative electrode cover of the button type battery and the sealing plastic ring on its outer peripheral wall. The control system 2 determines the quality of the sealing plastic ring on the outer peripheral wall of the negative electrode cover of the button type battery according to the pictures taken by the camera 14 of the detection mechanism 1'. If the quality of the sealing plastic ring on the outer peripheral wall of the negative electrode cover of the button type battery does not meet the standards, such as the sealing plastic ring on the outer peripheral wall of the negative electrode cover of the button type battery is not fully injected, a control signal is sent to the gas nozzle device 15 of the detection mechanism 1' to make the gas nozzle device 15 of the detection mechanism 1' spray gas to The button-type battery negative electrode cap whose sealing plastic ring on the outer peripheral wall does not meet the quality standard is blown out of the turntable 11 of the testing mechanism 1' and collected in the waste collection box 17 of the testing mechanism 1'; if the quality standard of the sealing plastic ring on the outer peripheral wall of the button-type battery negative electrode cap is met, the button-type battery negative electrode cap whose sealing plastic ring meets the quality standard continues to rotate with the turntable 11 of the testing mechanism 1', and when it rotates to the dial plate 16 of the testing mechanism 1', it is guided by the dial plate 16 of the testing mechanism 1', and is pushed out of the turntable 11 of the testing mechanism 1', and is collected in the qualified product collection box 18.

[0035] In the button-type battery negative electrode cover molded part detection device of the present invention, since the button-type battery negative electrode cover is relatively small in size, the position sensing device 12 of the two detection mechanisms (1, 1') for detecting the position information of the button-type battery negative electrode cover is usually arranged relatively low, below the light source 13; and in order to prevent the shadow of the camera device 14 from affecting the imaging of the button-type battery negative electrode cover directly below the light source 13, the camera device 14 is arranged above the light source 13.

[0036] In the detection device for the button battery negative electrode cover plastic parts of the present invention, the light source 13 is annular, and the annular light source 13 can make the brightness of the button battery negative electrode cover directly below it more uniform, and the imaging effect of the button battery negative electrode cover is better and clearer. In the detection mechanism used to detect the quality of the sealing plastic ring on the inner peripheral wall of the button battery negative electrode cover, the light source 13 is a blue light source. Since the sealing plastic ring is transparent, and the inner peripheral wall of the button battery negative electrode cover is concave, under the illumination of the light source 13 which is a blue light source, in the photo taken by the camera device 14 of the button battery negative electrode cover, the image of the button battery negative electrode cover is black, and the image of the sealing plastic ring on its inner peripheral wall is grayish white. In the detection mechanism for detecting the quality of the sealing plastic-embedded ring on the outer peripheral wall of the button-type battery negative electrode cover, the light source 13 is any one of a blue light source or a white light source, that is, both a blue light source and a white light source can be used. Regardless of whether the light source 13 in the detection mechanism is a blue light source or a white light source, in the photos taken by the camera device 14 on the button-type battery negative electrode cover, the image of the button-type battery negative electrode cover is black, and the image of the sealing plastic-embedded ring on its inner peripheral wall is grayish white. Experiments have found that only under the action of the specific light source 13 in the detection mechanism, the image color of the button-type battery negative electrode cover and the sealing plastic-embedded ring on its inner and outer peripheral walls will have a strong contrast and can be clearly distinguished, and the control system 2 can recognize the image of the sealing plastic-embedded ring and make quality judgments based on the image.

[0037] The button battery negative electrode cover plastic-embedded part detection device of the present invention senses the position of the button battery negative electrode cover on the turntable 11 through the position sensing device 12 of the detection mechanism, so that the control system 2 controls the camera device 14 to take a photo of the button battery negative electrode cover under the light source 13, so that the button battery negative electrode cover under the light source 13 and the sealing plastic-embedded ring on the inner peripheral wall or the outer peripheral wall form an image with strong color contrast, that is, the image of the sealing plastic-embedded ring on the inner peripheral wall or the outer peripheral wall of the button battery negative electrode cover can be distinguished and identified through the photo. Since the image formed is different when the quality of the sealing plastic-embedded ring on the inner peripheral wall or the outer peripheral wall of the button battery negative electrode cover meets the standard or does not meet the standard (such as incomplete injection molding or glue overflow), when the quality of the sealing plastic-embedded ring on the inner peripheral wall or the outer peripheral wall of the button battery negative electrode cover meets the standard, the image formed by the sealing plastic-embedded ring on the inner peripheral wall or the outer peripheral wall of the button battery negative electrode cover is evenly distributed in an annular shape, and the button battery negative electrode cover is uniformly distributed in an annular shape. When the quality of the sealing plastic ring on the inner wall or outer wall of the cover does not meet the standard, the image formed by the sealing plastic ring on the inner wall or outer wall of the button-type battery negative electrode cover is just the opposite, with a non-uniform annular distribution. For example, if there is a break in the image or the inner edge extends inward, the control system 2 can quickly and effectively analyze and determine the quality of the button-type battery negative electrode cover and the sealing plastic ring on its inner wall or outer wall based on the photo taken by the camera device 14, that is, the image formed by the sealing plastic ring on the inner wall or outer wall of the button-type battery negative electrode cover and the inner wall or outer wall thereof. At the same time, through the control of the control system 2 on the gas nozzle device 15, the button-type battery negative electrode cover whose inner wall or outer wall sealing plastic ring does not meet the standard can be separated in time, thereby realizing automatic detection of the plastic parts on the button-type battery negative electrode cover, and compared with the rough ore detection by artificial vision, the detection of the plastic parts on the button-type battery negative electrode cover of the present invention is more reliable and efficient.

[0038] In the detection device for the negative electrode cover of a button-type battery of the present invention, the in-place sensing device 12 of the detection mechanism can be a proximity sensor or a photoelectric sensor. Compared with the proximity sensor with poor sensitivity, preferably, the in-place sensing device 12 includes a light emitting element 121 and a light detecting element 122 located on the optical path of the light emitting element 121, and the light detecting element 122 is connected to the control system 2 for communication. In this setting, when working, the light detecting element 122 of the in-place sensing device 12 detects the light signal emitted by the light emitting element 121, and converts the light signal into an electrical signal and sends it to the control system 2. The control system 2 receives the electrical signal sent by the light detecting element 122 of the in-place sensing device 12, and determines whether to send a control signal to the camera device 14 according to the electrical signal, so as to control the camera device 14 whether to take a photo of the negative electrode cover of the button-type battery that rotates with the turntable 11 to be located directly below the light source 13.

[0039] The button-type battery negative electrode cover molded parts detection device of the present invention is used to collect the button-type battery negative electrode covers that are not up to standard and are ejected from the turntable 11 by the gas nozzle device 15. Preferably, a waste collection box 17 is provided on one side of the turntable 11 of the detection mechanism (1, 1') and is located on the horizontal projection of the gas path ejected by the gas nozzle device 15.

[0040] The button-type battery negative electrode cover molded parts detection device of the present invention can manually place the button-type battery negative electrode cover on the turntable 11 of the detection mechanism, or can place the button-type battery negative electrode cover on the turntable 11 of the detection mechanism by a manipulator such as a suction cup. In order to make the structure simpler, the feeding speed faster, and the degree of automation higher, preferably, the button-type battery negative electrode cover molded parts detection device includes a feeding conveyor belt 10 and a first feeding gear 20, the feeding conveyor belt 10 is close to the turntable 11 of the detection mechanism, the first feeding gear 20 is driven by the first power mechanism 201 and can be rotatably installed on the frame 100, and the first feeding gear 20 is horizontally arranged and spans the adjacent feeding conveyor belt 10 and the turntable 11. During operation, the button-type battery negative electrode cover is on the feeding conveyor belt 10, and when it is transported to the first feeding gear 20 by the feeding conveyor belt 10, it enters the tooth groove of the first feeding gear 20, and is brought to the corresponding turntable 11 of the detection mechanism 1 by the rotating first feeding gear 20.

[0041] The device for detecting the plastic-embedded parts of the negative electrode cover of a button-type battery of the present invention, in the detection mechanism 1 for detecting the quality of the sealing plastic-embedded ring on the inner peripheral wall of the negative electrode cover of the button-type battery, the number of the camera devices 14 of the present invention can be one, two or more. Regardless of the number of the camera devices 14 being one, two or more, the image formed by the camera device 14 on the negative electrode cover of the button-type battery directly below can more or less reflect the condition of the sealing plastic-embedded ring on the inner peripheral wall of the negative electrode cover of the button-type battery, but it may not be able to fully and clearly reflect the condition of the sealing plastic-embedded ring on the inner peripheral wall of the negative electrode cover of the button-type battery. For example, the image formed by a vertically arranged camera device 14 on the negative electrode cover of the button-type battery directly below can only clear the bottom surface inside the negative electrode cover of the button-type battery and the sealing plastic-embedded ring overflowing on the bottom surface due to the concave inner peripheral wall of the negative electrode cover of the button-type battery. That is to say, a vertically arranged camera device 14 can only clearly reflect whether the sealing plastic ring on the inner circumference of the button type battery negative electrode cover has overflowed glue toward the bottom surface of the button type battery negative electrode cover, but cannot clearly reflect whether the sealing plastic ring on the inner circumference of the button type battery negative electrode cover is not fully injected. Therefore, if there is only one vertically arranged camera device 14 in the detection mechanism 1 for detecting the quality of the sealing plastic ring on the inner circumference of the button type battery negative electrode cover, it can only detect defective products with "overflowing glue" of the sealing plastic ring on the inner circumference of the button type battery negative electrode cover, but cannot detect defective products with "incomplete injection" of the sealing plastic ring on the inner circumference of the button type battery negative electrode cover, and the detection rate of defective products is relatively low. In order to detect defective products with substandard quality of the sealing plastic ring on the inner wall of the negative electrode cover of the button type battery 100 without installing too many camera devices 14, preferably, when the detection mechanism 1 is used to detect the quality of the sealing plastic ring on the inner wall of the negative electrode cover of the button type battery, the number of camera devices 14 is three, one of which is vertically arranged, and the other two camera devices 14 are symmetrically distributed inwardly on both sides of the vertically arranged camera device 14. Under this preferred mode, the middle camera device 14 can clearly reflect whether the sealing plastic ring on the inner circumference of the button battery negative electrode cover has overflowed glue to the bottom surface of the button battery negative electrode cover, thereby detecting defective products with "overflowing glue" of the sealing plastic ring on the inner circumference of the button battery negative electrode cover; the camera devices 14 arranged inwardly at both sides can clearly image the sealing plastic ring on the circumference of the button battery negative electrode cover, and clearly reflect whether the sealing plastic ring on the inner circumference of the button battery negative electrode cover is not fully injected, thereby detecting defective products with "incomplete injection" of the sealing plastic ring on the inner circumference of the button battery negative electrode cover.

[0042] In the button cell negative electrode cover plastic insert detection device of the present invention, since blue light sources are more harmful to human eyes, in the detection mechanism 1' for detecting the quality of the sealing plastic insert ring on the outer peripheral wall of the button cell negative electrode cover, the light source 13 is preferably a white light source.

[0043] The button-type battery negative electrode cover plastic-embedded parts detection device of the present invention is designed to improve the uniformity of illumination, enhance the contrast of the image formed by the button-type battery negative electrode cover and the sealing plastic-embedded ring on its outer peripheral wall, and more clearly reflect the condition of the sealing plastic-embedded ring on the outer peripheral wall of the button-type battery negative electrode cover. Preferably, in the detection mechanism 1' for detecting the quality of the sealing plastic-embedded ring on the outer peripheral wall of the button-type battery negative electrode cover, a coaxial light source 130 having the same color as the light source 13 is further provided on the frame 100. Since the structure of the coaxial light source 130 belongs to the existing conventional structure, the present invention will not explain the structure of the coaxial light source 130 in detail.

[0044] When the sealing plastic ring is injection molded onto the negative electrode cover of the button type battery, the negative electrode cover of the button type battery is installed in a fixed seat and is integrated with the fixed seat. During the injection molding process, the sealing plastic ring on the outer peripheral wall of the negative electrode cover of the button type battery will not overflow to the outer surface. Therefore, the "incomplete injection molding" of the sealing plastic ring on the outer peripheral wall of the negative electrode cover of the button type battery is the main factor causing the quality of the sealing plastic ring on the outer peripheral wall of the negative electrode cover of the button type battery to fail to meet the standards. The button-type battery negative electrode cover plastic-embedded part detection device of the present invention can detect the quality of the sealing plastic-embedded ring on the outer peripheral wall of the button-type battery negative electrode cover by one, two or more camera devices 14. Regardless of the number of camera devices 14, the image formed by the camera device 14 on the button-type battery negative electrode cover directly below can more or less reflect the condition of the sealing plastic-embedded ring on the outer peripheral wall of the button-type battery negative electrode cover, but it may not be able to fully and clearly reflect the condition of the sealing plastic-embedded ring on the inner peripheral wall of the button-type battery negative electrode cover. For example, if a tilted camera device 14 takes a photo of the button-type battery negative electrode cover directly below it, the photo taken can only show the button-type battery negative electrode cover. The portion of the sealing plastic ring on the outer peripheral wall of the battery negative electrode cover under one viewing angle cannot fully display a circle of the sealing plastic ring on the outer peripheral wall of the button type battery negative electrode cover. Therefore, an inclined camera device 14 can only reflect whether the portion of the sealing plastic ring on the outer peripheral wall of the button type battery negative electrode cover shown in the photo is not fully injected, but cannot reflect whether a complete circle of the sealing plastic ring on the outer peripheral wall of the button type battery negative electrode cover is not fully injected. In other words, for defective products in which the portion of the sealing plastic ring shown in the photo is fully injected and the portion of the sealing plastic ring not photographed is not fully injected, it cannot be detected, and the detection rate of defective products is relatively low. In order to detect 100% of the defective products whose quality of the sealing plastic ring on the outer peripheral wall of the button-type battery negative electrode cover does not meet the standard, and at the same time, there is no need to install too many camera devices 14, preferably, in the detection mechanism 1' for detecting the quality of the sealing plastic ring on the outer peripheral wall of the button-type battery negative electrode cover, the number of camera devices 14 is one, and it is vertically arranged. In this preferred mode, the vertically arranged camera device 14 can completely capture a circle of the sealing plastic ring on the outer peripheral wall of the button-type battery negative electrode cover, which can clearly reflect whether the sealing plastic ring on the outer peripheral wall of the button-type battery negative electrode cover is not fully injected, thereby detecting defective products whose sealing plastic ring on the outer peripheral wall of the button-type battery negative electrode cover is "not fully injected".

[0045] The device for detecting the plastic-embedded parts of the negative electrode cover of a button-type battery of the present invention can have one, two or more detection mechanisms. One detection mechanism can perform incomplete detection on the quality of the sealing plastic-embedded rings on the inner and outer peripheral walls of the negative electrode cover of the button-type battery, and the detection rate of defective products is low. In order to achieve continuous, rapid and comprehensive detection of the sealing plastic-embedded rings on the negative electrode cover of the button-type battery, preferably, there are two detection mechanisms, and the processes of the two detection mechanisms are connected in sequence, wherein one detection mechanism is used to detect the quality of the sealing plastic-embedded ring on the inner peripheral wall of the negative electrode cover of the button-type battery, and the other detection mechanism is used to detect the quality of the sealing plastic-embedded ring on the outer peripheral wall of the negative electrode cover of the button-type battery.

[0046] The button-type battery negative electrode cover plastic-embedded parts detection device of the present invention is provided with two detection mechanisms to carry out continuous and comprehensive detection of the sealing plastic-embedded rings on the inner and outer peripheral walls of the button-type battery negative electrode cover. The quality of the sealing plastic-embedded ring on the inner peripheral wall of the button-type battery negative electrode cover can be detected first, and then the quality of the sealing plastic-embedded ring on the outer peripheral wall of the button-type battery negative electrode cover can be detected. Alternatively, the quality of the sealing plastic-embedded ring on the outer peripheral wall of the button-type battery negative electrode cover can be detected first, and then the quality of the sealing plastic-embedded ring on the inner peripheral wall of the button-type battery negative electrode cover can be detected. When testing the quality of the sealing plastic ring on the inner circumference of the negative electrode cover of a button battery, the cover opening of the negative electrode cover of the button battery faces upward, and when testing the quality of the sealing plastic ring on the outer circumference, the cover opening of the negative electrode cover of the button battery faces downward. The button battery negative electrode cover that is in a mess before testing can be easily formed into a posture with the cover opening facing upward through shaping, and it is found in production that the probability of unqualified quality of the sealing plastic ring on the inner circumference of the negative electrode cover of a button battery is higher than the probability of unqualified quality of the sealing plastic ring on the outer circumference. Therefore, in order to make the specified posture of the negative electrode cover of the button battery easier to obtain before testing and defective products can be quickly detected during testing, preferably, the testing mechanism in the previous process is used to detect the quality of the sealing plastic ring on the inner circumference of the negative electrode cover of the button battery, and the testing mechanism in the later process is used to detect the quality of the sealing plastic ring on the outer circumference of the negative electrode cover of the button battery.

[0047] The button-type battery negative electrode cover molded parts detection device of the present invention can manually flip over a normal button-type battery negative electrode cover that has not been sprayed away by the gas nozzle device 15 on the turntable 11 of the detection mechanism in the previous process and transfer it to the turntable 11 of the detection mechanism in the subsequent process, or can flip over a normal button-type battery negative electrode cover that has not been sprayed away by the gas nozzle device 15 on the turntable 11 of the detection mechanism in the previous process and transfer it to the turntable 11 of the detection mechanism in the subsequent process by other means such as a suction cup flipping robot. In order to make the structure simpler, the feeding speed faster and the automation higher, preferably, the button battery negative electrode cover inlay molding detection device also includes a transition conveyor belt 30 and a second feeding gear 40, the transition conveyor belt 30 includes an upper conveyor belt 301 and a lower conveyor belt 302 which are vertically stacked and arranged in opposite conveying directions, and an arc-shaped flip guide plate 303 is provided at the output end of the upper conveyor belt 301, the flip guide plate 303 is upright and the gap surrounds the end of the output end of the upper conveyor belt 301, in the vertical direction, the upper end of the flip guide plate 303 is higher than the upper surface of the upper conveyor belt 301, the lower end of the flip guide plate 303 is close to the upper surface of the lower conveyor belt 302, and the gap between the flip guide plate 303 and the upper conveyor belt 301 forms a The flip channel 304 of the button battery negative electrode cover, the upper conveyor belt 301 is on the removal path of the button battery negative electrode cover at a position where the dial 16 is provided near the turntable 11 of the detection mechanism in the previous process. During operation, the dial 16 on the turntable 11 of the detection mechanism in the previous process can push the normal negative electrode cover that rotates with the turntable 11 to the position of the dial 16 onto the upper conveyor belt 301, and one side of the output end of the lower conveyor belt 302 is close to the turntable 11 of the detection mechanism in the later process. The second feed gear 40 is driven by the second power mechanism 401 and can be rotatably installed on the frame 100. The second feed gear 40 is horizontally arranged and spans the lower conveyor belt 301 of the transition conveyor belt 30 and the turntable 11 of the detection mechanism in the later process. During operation, the normal button-type battery negative electrode caps on the turntable 11 of the detection mechanism in the previous process that have not been sprayed away by the gas nozzle device 15, when the turntable 11 rotates to the dial plate 16, are pushed away from the turntable 11 and enter the upper conveyor belt 301 of the transition conveyor belt 30 under the guidance of the dial plate 16, and are transported together with the upper conveyor belt 301. When they are transported to the output end of the upper conveyor belt 301, they enter the flip channel 304. The button-type battery negative electrode caps in the flip channel 304 are vertically flipped 180° under the limitation of the flip guide plate 303 and enter the lower conveyor belt 302, and then are transported to the second feed gear 40 together with the lower conveyor belt 302, enter the tooth groove of the second feed gear 40, and are brought to the turntable 11 of the detection mechanism in the subsequent process by the rotating second feed gear 40.

[0048] The button-type battery negative electrode cap inlay molding detection device of the present invention is preferably provided with a qualified product collection box 18 on one side of the turntable 11 of the detection mechanism with a later process, and the qualified product collection box 18 is close to the position where the turntable 11 of the detection mechanism with a later process is provided with a dial plate 16. During operation, when the qualified products on the turntable 11 of the detection mechanism with a later process rotate with the turntable 11 to the dial plate 16, they are pulled away from the turntable 11 under the guidance of the dial plate 16 and fall into the qualified product collection box 18. The provision of the qualified product collection box 18 facilitates the collection of button-type battery negative electrode caps that meet the quality standards.

[0049] The button battery negative electrode cover plastic insert detection device of the present invention can detect Figure 1 The seal ring on the negative electrode cover of the button battery shown in the figure can also be used to distinguish Figure 1 The button-type battery negative electrode cover and the sealing ring are tested. That is to say, the structure of the button-type battery negative electrode cover and the sealing ring is not limited to Figure 1 shown.

[0050] The present invention is not limited to the embodiments. For ordinary technicians in the technical field to which the present invention belongs, they can make several simple deductions or substitutions without departing from the concept of the present invention, which should be regarded as belonging to the protection scope of the present invention.
