Description

Technical Field

[0001] This invention relates to the field of battery packaging inspection equipment, specifically, an insulation testing system. Background Technology

[0002] In the current field of mechanized battery processing in China, after the batteries are packaged and coated, they need to be tested to check whether they are all covered with PVC film. However, the current testing process mostly uses cameras to capture images and then compare them with the system. This method has large errors due to factors such as lighting or camera, and poor imaging quality can easily affect the coating test.

[0003] Therefore, accurately and quickly inspecting the shell after coating is an extremely important step in improving production efficiency and ensuring product quality. Summary of the Invention

[0004] The purpose of this invention is to provide an insulation detection system to perform coating detection on zinc shells after coating is completed and to remove uncoated zinc shells from the production line.

[0005] To achieve the above objectives, the present invention employs the following technical means:

[0006] An insulation testing system includes a support mechanism;

[0007] The bearing mechanism is equipped with a conductive material conveying mechanism;

[0008] The bearing mechanism is provided with an electrical connection mechanism and a material recovery mechanism in sequence along the material conveying direction of the conductive conveying mechanism;

[0009] The power connection mechanism and the material recovery mechanism are connected via a control terminal signal from a built-in timing module.

[0010] Preferably, the current receiving mechanism includes a current detection unit and a current receiving unit, the current receiving unit being connected to the material recycling mechanism via a control terminal signal, and the current detection unit being a soft conductive needle.

[0011] Furthermore, the material recycling mechanism includes a pulse blowing device that is signal-connected to the control terminal. The outlet of the pulse blowing device faces the conductive conveying mechanism, and when the pulse blowing device is running, the outlet faces the material trough of the conductive conveying mechanism. The material recycling mechanism also includes a housing recycling box located on the opposite side of the pulse blowing paper loading mechanism, with the inlet of the housing recycling box facing the conductive conveying mechanism.

[0012] Furthermore, the conductive material conveying mechanism includes a conveying mechanism whose bearing part is made of conductive material, and a material receiving mechanism is conductively installed on the material bearing part of the conveying mechanism. The material receiving mechanism has a built-in contact section that is conductive to the battery casing.

[0013] Furthermore, the conveying mechanism includes at least one pair of double-row sprockets, the two double-row sprockets are connected by a metal chain drive, and the material receiving mechanism is sequentially arranged between the two metal chains, and the material receiving mechanism is conductively connected to the metal chains.

[0014] Furthermore, the material receiving mechanism is configured corresponding to the links of the metal chain, and each link of the metal chain is equipped with one of the material receiving mechanisms, and each material receiving mechanism is connected to one link of the two metal chains on both sides.

[0015] Furthermore, a horizontal receiving plate is installed on the side of the metal chain facing the other metal chain and at each link. The receiving plate is made of conductive material. The material receiving mechanism is embedded in the top surface of the receiving plate, and the contact section is connected to the receiving plate.

[0016] Furthermore, the material receiving mechanism includes a support base, the bottom surface of which is provided with an inlay groove for embedding the receiving plate, the top surface of which is provided with a material groove, and a conductive post is provided inside the support base, one end of which extends into the material groove and the other end contacts and conducts communication with the receiving plate.

[0017] Furthermore, two symmetrical receiving plates are embedded in the inlay groove.

[0018] Furthermore, the inner wall of the material trough is arc-shaped, the axis of the material trough is horizontal and perpendicular to the conveying direction of the conveying mechanism, and the height of the side of the material trough facing the conveying direction of the conveying mechanism is lower than the height of the side of the material trough facing away from the conveying direction of the conveying mechanism.

[0019] The present invention has the following beneficial effects during use:

[0020] First, the zinc shell material that has completed the coating process is transported on a conductive conveying mechanism. Under the action of the conductive conveying mechanism, current is continuously pumped into the zinc shell material. Then, during the transportation process, when the zinc shell material moves with the conductive conveying mechanism to the position of the electrical connection structure, it comes into contact with the current detection end of the electrical connection structure. The zinc shell material covered with a thin film has insulating properties, so the electrical signal receiving end of the electrical connection structure cannot receive a current signal at this time. However, when the zinc shell material without a thin film comes into contact with the aforementioned current detection end, due to the conductive properties of the zinc shell, the aforementioned electrical signal receiving end receives a current signal. At this time, it is a product without a coating, that is, a substandard zinc shell, which is detected. After the power receiving mechanism receives the electrical signal, the signal is input to the control terminal, and then the timing module is activated. Since the material conveying mechanism has a fixed material speed and the distance between the material recovery mechanism and the power receiving mechanism is fixed, after the timing module completes the timing, the uncoated zinc shells detected above are transported to the material recovery mechanism. Then, under the action of the material recovery mechanism, the uncoated zinc shells are discharged from the production line, thereby effectively improving the product qualification rate of the production line and effectively avoiding the occurrence of a large number of missed inspections caused by external factors such as light when using optical imaging inspection.

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0035] The insulation status of the battery materials after the coating is tested and explained in detail below.

[0036] Please refer to Figures 1 to 7 As shown, an insulation testing system includes a support mechanism;

[0037] The bearing mechanism is equipped with a conductive material conveying mechanism 100;

[0038] The bearing mechanism is provided with an electrical receiving mechanism 200 and a material recovery mechanism 300 in sequence along the material conveying direction of the conductive material conveying mechanism 100.

[0039] The power connection mechanism 200 and the material recycling mechanism 300 are connected by a control terminal signal with a built-in timing module.

[0040] In this way, the zinc shell material that has completed the coating process is transported on the conductive conveying mechanism 100. Under the action of the conductive conveying mechanism 100, current is continuously pumped into the zinc shell material. Then, during the transportation process, when the zinc shell material moves with the conductive conveying mechanism 100 to the position of the electrical connection structure, it comes into contact with the current detection end of the electrical connection mechanism 200. The zinc shell material covered with a thin film has insulating properties, so the electrical signal receiving end of the electrical connection mechanism 200 cannot receive a current signal at this time. However, when the zinc shell material without a thin film comes into contact with the aforementioned current detection end, due to the conductive properties of the zinc shell, the aforementioned electrical signal receiving end receives a current signal. At this time, it is a product without a film, that is, a substandard zinc shell is detected. After the power receiving mechanism 200 receives the electrical signal, its signal is input to the control terminal, and then the timing module is activated. Since the clinker speed of the conductive conveying mechanism 100 is fixed, and the distance between the material recovery mechanism 300 and the power receiving mechanism 200 is fixed, after the timing module completes the timing, the uncoated zinc shells detected above are transported to the material recovery mechanism 300. Then, under the action of the material recovery mechanism 300, the uncoated zinc shells are discharged from the production line, thereby effectively improving the product qualification rate of the production line and effectively avoiding the occurrence of a large number of missed inspections caused by external factors such as light when using optical imaging inspection.

[0041] Furthermore, multiple timing modules can be set within the system, the specific number of which depends on the amount of material between the power receiving mechanism 200 and the material recycling mechanism 300. Each timing module is arranged sequentially according to a timestamp, further minimizing the possibility of missed detections.

[0042] Furthermore, the power receiving mechanism 200 includes a current detection unit 201 and a current receiving unit 202. The current receiving unit 202 is connected to the material recycling mechanism 300 via the control terminal signal. The current detection unit 201 is a soft conductive needle.

[0043] The aforementioned soft conductive needle makes sliding contact with the top surface of the zinc shell.

[0044] Furthermore, the material recycling mechanism 300 includes a pulse blowing device 301 that is signal-connected to the control terminal. The outlet end of the pulse blowing device 301 faces the conductive conveying mechanism 100, and when the pulse blowing device 301 is running, the outlet end is directly opposite the material trough of the conductive conveying mechanism 100. The material recycling mechanism 300 also includes a housing recycling box 302 located on the opposite side of the pulse blowing paper loading, and the inlet end of the housing recycling box 302 faces the conductive conveying mechanism 100.

[0045] In this way, when the pulse blowing device 301 is running, the zinc shell material can be blown from the material tank into the shell recovery box 302.

[0046] Furthermore, the aforementioned conductive material conveying mechanism 100 includes a conveying mechanism 110 whose bearing part is made of conductive material. The material receiving part of the conveying mechanism 110 is conductively installed with a material receiving mechanism 120, and the material receiving mechanism 120 has a built-in contact section that is conductive to the battery casing.

[0047] In this way, during the material conveying process using the conductive conveyor chain, the encapsulated shell material is placed on the material receiving mechanism 120, and the contact section built into the battery receiving structure is in contact with the surface of the shell. After the conveying mechanism 110 is connected to the positive terminal of the external power supply, the positive terminal of the external power supply can continuously conduct current to the position of the shell, so that the shell can always be connected to the positive power supply as it moves with the conveying mechanism 110, which facilitates subsequent testing.

[0048] More specifically regarding the conveying mechanism 110, the conveying mechanism 110 includes at least one pair of double-row sprockets 111. The two double-row sprockets 111 are connected by a metal chain 112, and the aforementioned double-row sprockets 111 can be connected to a positive power source for outputting current, thereby transmitting power to the housing located on the material receiving mechanism 120. Furthermore, the material receiving mechanism 120 is sequentially arranged between the two metal chains 112, and the material receiving mechanism 120 is electrically connected to the metal chains 112.

[0049] Furthermore, the material receiving mechanism 120 is correspondingly arranged with the links 1121 of the metal chain 112. Each link 1121 of the metal chain 112 is equipped with one material receiving mechanism 120, and both sides of each material receiving mechanism 120 are conductively connected to one link 1121 of each of the two metal chains 112. In this way, by using the material receiving mechanism 120 provided on each link 1121 of the metal chain 112, adjacent material receiving mechanisms 120 will not be in contact with each other, thereby avoiding mutual interference between the states of adjacent shells.

[0050] Furthermore, regarding the installation of the material receiving mechanism 120, a horizontal receiving plate 113 is installed on the side of the metal chain 112 facing the other metal chain 112, at the position of each link 1121. The receiving plate 113 is made of conductive material, and the material receiving mechanism 120 is embedded in the top surface of the receiving plate 113, with the contact section communicating with the receiving plate 113. This arrangement of the receiving plate 113 embedded in the link 1121 and the material receiving mechanism 120 facilitates subsequent maintenance of the material receiving mechanism 120.

[0051] Furthermore, the material receiving mechanism 120 includes a support base 121. The bottom surface of the support base 121 has an inlay groove 122 for embedding the receiving plate 113. The top surface of the support base 121 has a material groove 123. A conductive post 124 is provided inside the support base 121. One end of the conductive post 124 extends into the material groove 123, and the other end contacts and conducts electricity with the receiving plate 113. The aforementioned conductive post 124 serves as the contact section between the material receiving mechanism 120 and the housing. Thus, after the entire conveying mechanism 110 is connected to an external positive power source, current can be transmitted to the housing through the conductive post 124. Furthermore, during the process of the housing moving along the conveying mechanism 110, the housing remains in contact with the conductive post 124, maintaining contact with the external current.

[0052] Furthermore, two symmetrical receiving plates 113 are embedded in the inlay groove 122.

[0053] Additionally, the end of the conductive post 124 exposed in the material tank 123 is the contact section.

[0054] In addition, in order to prevent the housing from being dislodged by external forces during the external testing process, the inner wall of the material trough 123 is designed to be arc-shaped. The axis of the material trough 123 is set horizontally and perpendicular to the conveying direction of the conveying mechanism 110. The height of the side of the material trough 123 facing the conveying direction of the conveying mechanism 110 is lower than the height of the side of the material trough 123 facing away from the conveying direction of the conveying mechanism 110.

[0055] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
