The lower inclined surface detection light source 1321 and the lower inclined surface detection camera 1322 are disposed below the detection gripper 113, and their optical axes are inclined relative to the rotating axis of the rotating gripper 1323.

[0066] In this embodiment, the end surface detection mechanism 13a, the cell detection mechanism 13b, the upper inclined surface detection mechanism 13c, the pin detection mechanism 13d, and the lower inclined surface detection mechanism 13e are sequentially distributed beside the detection turntable 111 along the rotation direction of the detection turntable 111.

[0067] When the end surface detection mechanism 13a detects the appearance of the upper and lower end surfaces of the capacitor, the detection gripper 113 first transports the capacitor to the position corresponding to the end surface detection mechanism 13a through the rotation of the detection turntable 111. The upper end surface detection light source 131 emits light toward the upper end surface of the capacitor to illuminate the upper end surface of the capacitor, and the upper end surface detection camera 132 captures the upper end surface of the capacitor to obtain an upper end surface image of the capacitor, thereby detecting the appearance of the upper end surface of the capacitor.

[0069] The upper end surface detection light source 131 and the lower end surface detection light source 133 mainly consist of a box with a window, a diffuse reflection glass and an LED light source.

The upper end surface detection camera 132 is located above the upper end surface detection light source 131, and the lower end surface detection camera 134 is located below the lower end surface detection light source 133, so that the upper end surface detection camera 132 and the lower end surface detection camera 134 respectively capture the upper end surface and the lower end surface of the capacitor through the windows of the upper end surface detection light source 131 and the lower end surface detection light source 133.

[0070] When the appearance of the peripheral surface of the electric core of the capacitor is detected by the electric core detection mechanism 13b, the detection gripper 113 first transports the capacitor to the working position corresponding to the electric core detection mechanism 13b through the self-rotation of the detection turntable 111. After the first lifting assembly 1310 drives the first rotating seat 138 to rise, the capacitor is released and placed on the first rotating seat 138. The electric core detection light source 136 emits light to the peripheral surface of the electric core of the capacitor to illuminate the peripheral surface of the electric core of the capacitor, and the electric core detection camera 137 captures the peripheral surface of the electric core of the capacitor. At the same time, the first rotating assembly 139 drives the first rotating seat 138 and the capacitor to rotate, so that the electric core detection camera 137 can obtain the peripheral images of the electric core of the capacitor in various directions through multiple captures, thereby detecting the appearance of the peripheral surface of the electric core of the capacitor.

[0071] The battery cell detection light source 136 is mainly composed of an upper light bar, a lower light bar and a light bar support, the upper light bar and the lower light bar are fixedly arranged on the light bar support and oppositely arranged. The battery cell detection camera 137 is arranged on the side of the battery cell detection light source 136 away from the first rotating seat 138, so as to shoot the periphery of the battery cell part of the capacitor through the gap between the upper light bar and the lower light bar.

[0072] When the upper inclined surface detection mechanism 13c detects the appearance of the upper inclined surface of the capacitor, the detection gripper 113 first transports the capacitor to the working position corresponding to the upper inclined surface detection mechanism 13c through the rotation of the detection turntable 111, and then releases the capacitor after the second rotating seat 1313 is lifted by the third lifting assembly 1314, so as to place the capacitor on the second rotating seat 1313; the upper inclined surface detection light source 1311 emits light to the upper inclined surface of the capacitor to illuminate the upper inclined surface of the capacitor, and the upper inclined surface detection camera 1312 shoots the upper inclined surface of the capacitor, and at the same time, the second rotating assembly 1314 rotates the capacitor to enable the upper inclined surface detection camera 1312 to obtain each upper inclined surface image of the capacitor through multiple shootings, so as to detect the appearance of the upper inclined surface of the capacitor.

[0073] It is particularly pointed out that the upper inclined surface refers to the upper end surface and the periphery of the capacitor, that is, the upper inclined surface detection camera 1312 needs to shoot the upper end surface and the periphery of the capacitor in the same image at the same time.

[0074] The upper inclined surface detection light source 1311 is a ring-shaped light source panel, the upper inclined surface detection camera 1312 is arranged on the side of the upper inclined surface detection light source 1311 away from the second rotating assembly 1314 and is aligned with the ring center of the upper inclined surface detection light source 1311, so as to shoot the upper inclined surface of the capacitor through the ring center of the upper inclined surface detection light source 1311.

[0075] When the pin detection mechanism 13d performs appearance detection on the pin periphery of the capacitor, the detection gripper 113 first transports the capacitor to the working position corresponding to the pin detection mechanism 13d through the self-rotation of the detection turntable 111, and then the fifth lifting assembly 1320 drives the third rotating seat 1318 to rise, and then the capacitor is loosened to be placed on the third rotating seat 1318; the pin detection light source 1316 emits light to the periphery of the pin part of the capacitor to illuminate the periphery of the pin part of the capacitor, and the pin detection camera 1317 photographs the periphery of the pin part of the capacitor, while the third rotating assembly 1319 drives the capacitor to rotate, so that the pin detection camera 1317 can obtain the periphery images of the pin part of the capacitor in each direction through multiple photographing, thereby performing appearance detection on the pin periphery of the capacitor.

[0076] In this embodiment, the pin detection light source 1316 is located on the side of the third rotating seat 1318 away from the detection turntable 111, and the pin detection camera 1317 is located on the side of the third rotating seat 1318 close to the detection turntable 111.

[0077] When the lower inclined surface detection mechanism 13e performs appearance detection on the lower inclined surface of the capacitor, the detection gripper 113 first transports the capacitor to the working position corresponding to the lower inclined surface detection mechanism 13e through the self-rotation of the detection turntable 111, and then the rotating gripper 1323 is tightened, and then the capacitor is loosened to be transferred to the rotating gripper 1323; the lower inclined surface detection light source 1321 emits light to the lower inclined surface of the capacitor to illuminate the lower inclined surface of the capacitor, and the lower inclined surface detection camera 1322 photographs the lower inclined surface of the capacitor, while the fourth rotating assembly 1324 drives the rotating gripper 1323 and the capacitor to rotate, so that the lower inclined surface detection camera 1322 can obtain the images of each lower inclined surface of the capacitor through multiple photographing, thereby performing appearance detection on the lower inclined surface of the capacitor.

[0078] It is particularly pointed out that the lower inclined surface refers to the lower end surface and the periphery of the capacitor, that is, the lower inclined surface detection camera 1322 needs to photograph the lower end surface and the periphery of the capacitor in the same image.

[0079] In this embodiment, the lower inclined surface detection light source 1321 is located directly below the detection gripper 113, and the pin detection camera 1317 is located on one side below the detection gripper 113.

[0080] In the production or transportation process of the capacitor, the capacitor often has a bulge on its bottom due to vibration, collision or internal short circuit, and the size of the bottom of the capacitor is small, so it is difficult to detect the bulge on the bottom by relying on the visual detection system alone.

[0081] Therefore, preferably, as shown in Figure 3 The appearance detection device 1 further comprises a bulge detection mechanism 15 arranged beside the corresponding station of the detection turntable 111, for detecting whether the capacitor has a bulge on its bottom, as shown in Figure 10 The bulge detection mechanism 15 comprises a limiting seat 151, a contact sensor 152 and a sixth lifting assembly 153, the sixth lifting assembly 153 is connected to drive the limiting seat 151 and the contact sensor 152 to lift; the limiting seat 151 is located below the detection gripper 113, and is provided with a limiting hole 150 for accommodating the capacitor; the contact sensor 152 comprises a sensing portion 1521 and a probe portion 1522, the sensing portion 1521 is located below the limiting seat 151, and one end of the probe portion 1522 is connected to the sensing portion 1521 and the other end extends into the limiting hole 150 of the limiting seat 151.

[0082] When the bulge detection mechanism 15 detects the bulge on the bottom of the capacitor, the detection gripper 113 first transports the capacitor to the station corresponding to the bulge detection mechanism 15 through the rotation of the detection turntable 111; the sixth lifting assembly 153 drives the limiting seat 151 and the contact sensor 152 to rise synchronously, in the rising process, the bottom of the capacitor first enters the limiting hole 150 of the limiting seat 151, and in the continuous rising process, the probe portion 1522 of the contact sensor 152 contacts the bottom of the capacitor, thereby triggering the sensing portion 1521 to form a sensing signal, if the capacitor has a bulge on its bottom, the rising amount of the probe portion 1522 is small, if the capacitor does not have a bulge on its bottom, the rising amount of the probe portion 1522 is large, by the triggering time of the sensing portion 1521, the rising amount of the probe portion 1522 can be calculated, thereby judging whether the capacitor has a bulge on its bottom.

[0083] The protrusion detection mechanism 15 can be located between any two appearance detection mechanisms 13. In the embodiment, the protrusion detection mechanism 15 is located between the end face detection mechanism 13a and the battery cell detection mechanism 13b.
