Description

Technical Field

[0001] This utility model relates to the field of capacitance detection technology, specifically to a turntable device. Background Technology

[0002] In the capacitor manufacturing process, capacitor appearance inspection equipment is generally used to photograph and inspect the appearance defects of the capacitor.

[0003] The turntable device of existing capacitor appearance inspection equipment generally includes a support base for supporting the capacitor and a clamping assembly for clamping the capacitor on the support base. The clamping assembly generally includes two opposing jaws and a cylinder. The cylinder drives the two jaws to close or open to clamp or release the capacitor on the support base. This type of clamping assembly can only clamp the capacitor, but cannot position the capacitor in the center of the support base, thus failing to guarantee the accuracy of the capacitor's position. When the appearance defect of the capacitor is photographed and inspected by the inspection device of the capacitor appearance inspection equipment, inaccurate detection is likely to occur, reducing the inspection accuracy. At the same time, using jaws to clamp the capacitor can easily scratch the capacitor. Utility Model Content

[0031] The following will clearly and completely describe the concept, specific structure, and technical effects of this utility model in conjunction with embodiments and accompanying drawings, so as to fully understand the purpose, features, and effects of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are all within the scope of protection of this utility model. Furthermore, all connections / linkages involved in the patent do not simply refer to direct contact between components, but rather to the ability to form a better connection structure by adding or reducing connecting accessories according to specific implementation conditions. The various technical features in this utility model can be combined interactively without contradicting each other.

[0032] Please refer to Figure 1 and Figure 2 An embodiment of the present invention provides a turntable device, including a turntable 10 and a turntable drive mechanism 20.

[0033] In practical applications, the turntable 10 is located above the frame of the capacitor appearance inspection equipment, and the turntable drive mechanism 20 is mounted on the frame. The turntable 10 is connected to the turntable drive mechanism 20, which drives the turntable 10 to rotate, for example, counterclockwise. Multiple fixture mechanisms 30 are sequentially spaced along the rotation direction of the turntable 10. These fixture mechanisms 30 are used to fix the capacitor 100 and can drive the capacitor 100 to rotate. In practical applications, each fixture mechanism 30 corresponds to one station of the capacitor appearance inspection equipment. The rotation of the turntable 10 can drive multiple fixture mechanisms 30 to pass through each station of the capacitor appearance inspection equipment in sequence. In this embodiment, the capacitor appearance inspection equipment has eight stations, where the first and last stations are the loading and unloading stations, respectively, and the remaining stations are inspection stations. The number of fixture mechanisms 30 corresponds to the number of stations, also being eight.

[0034] Combination Figures 3 to 8 As shown, the fixture mechanism 30 includes a support shaft 31 for supporting the capacitor 100 and a centering clamping assembly for clamping the capacitor 100 on the support shaft 31. The support shaft 31 passes through a through hole in the turntable 10 and has an adsorption cavity 311 extending axially therethrough. A sealing ring 312 is provided at the top end of the support shaft 311, and the adsorption cavity 311 is located inside the sealing ring 312. A support bearing seat 313 is rotatably fitted around the outer periphery of the support shaft 31. The support bearing seat 313 is disposed in the through hole of the turntable 10, and a portion of the support bearing seat 313 protrudes from the top end of the turntable 10. The support bearing seat 313 provides support for the rotation of the support shaft 31.

[0035] The centering clamping assembly includes an opening / closing wheel 32 and three straightening arms 33. The opening / closing wheel 32 is rotatably sleeved on the outer periphery of the support shaft 31 and located above the support bearing seat 313. Part of the opening / closing wheel 32 is accommodated in a recessed groove at the top of the support bearing seat 313, while part of the support bearing seat 313 protrudes from the outer wall of the opening / closing wheel 32. In this embodiment, an opening / closing wheel bearing 326 is provided within the inner hole 325 of the opening / closing wheel 32. The opening / closing wheel bearing 326 is sleeved on the outer periphery of the support shaft 31 to provide support for the rotation of the opening / closing wheel 32. The number of opening / closing wheel bearings 326 can be set according to actual conditions. The three straightening arms 33 are located above the opening / closing wheel 32 and are spaced apart around the support shaft 31. The opening and closing wheel 32 is circumferentially spaced with three mounting shafts 3221 corresponding to the three straightening arms 33. In this embodiment, the outer wall of the opening and closing wheel 32 is circumferentially spaced with three protrusions 322, and the top of each of the three protrusions 322 is respectively provided with the three mounting shafts 3221. The straightening arm 33 is rotatably sleeved on the outer periphery of the corresponding mounting shaft 3221, and the first end and the second end of the straightening arm 33 are respectively located on both sides of the corresponding mounting shaft 3221. In this embodiment, the first end of the straightening arm 33 is located on the counterclockwise side of the corresponding mounting shaft 3221, and the second end of the straightening arm 33 is located on the clockwise side of the corresponding mounting shaft 3221. The first ends of the three straightening arms 33 are close to the support shaft 31 and are provided with correction wheels 332. The correction wheels 332 are located above the support shaft 31. The second ends of the straightening arms 33 extend away from the support shaft 31 and are provided with connecting wheels 333. In this embodiment, the second end of the straightening arm 33 is provided with a mounting rod 334, and the end of the mounting rod 334 is provided with the connecting wheel 333. The top end of the support bearing seat 313 is provided with three mounting grooves 3132 corresponding to the three straightening arms 33 in a circumferentially spaced manner. In this embodiment, the top end of the support bearing seat 313 is provided with three bosses 3131 in a circumferentially spaced manner. The top ends of the three bosses 3131 are respectively provided with the three mounting grooves 3132. The second ends of the three straightening arms 33 are respectively located above the three bosses 3131. The connecting wheels 333 of the straightening arms 33 cooperate with the corresponding mounting grooves 3132.The rotation of the opening and closing wheel 32 can drive the first ends of the three straightening arms 33 to move towards or away from the support shaft 31. Specifically, when the opening and closing wheel 32 rotates counterclockwise, under the action of the mounting shaft 3221, it can drive the first ends of the three straightening arms 33 to move away from the support shaft 31, thereby driving the correction wheels 332 of the three straightening arms 33 to move away from the support shaft 31. Thus, the capacitor 100 on the support shaft 31 can be released through the correction wheels 332 of the three straightening arms 33. When the opening and closing wheel 32 rotates clockwise, under the action of the mounting shaft 3221, it can drive the first ends of the three straightening arms 33 to move towards the support shaft 31, thereby driving the correction wheels 332 of the three straightening arms 33 to move towards the support shaft 31. Thus, the correction wheels 332 of the three straightening arms 33 can be released through the correction of the three straightening arms 33. The wheel 332 can clamp the capacitor 100 on the support shaft 31. By clamping the capacitor 100 on the support shaft 31 with the correction wheels 332 of the three straightening arms 33, the capacitor 100 can be fixed. When clamping the capacitor 100, the correction wheels 332 form rolling contact with the capacitor 100, preventing scratches. Furthermore, by using three straightening arms 33, when the axis of the capacitor 100 is not collinear with the axis of the support shaft 31 (i.e., the capacitor 100 is misaligned), as the first ends of the three straightening arms 33 approach each other, they can push the capacitor 100 towards the axis of the support shaft 31. This corrects the position of the capacitor 100, ensuring that its axis is collinear with the axis of the support shaft 31, thus positioning the capacitor 100 at the center of the support shaft 31. Understandably, in other embodiments, the number of straightening arms 33 can be different, such as four, five, or six, depending on the actual situation.

[0036] In this embodiment, a protrusion 331 is formed at the top of the first end of the straightening arm 33, and the top of the protrusion 331 is provided with the correction wheel 332. The straightening arm 33 is provided with a straightening arm through hole 335, through which the straightening arm 33 is rotatably sleeved on the outer periphery of the corresponding mounting shaft 3221. A straightening arm bearing 3222 is provided in the straightening arm through hole 335, and the straightening arm bearing 3222 is sleeved on the outer periphery of the corresponding mounting shaft 3221. A connecting sleeve 336 is provided at the bottom end of the straightening arm 33, and the connecting sleeve 336 is rotatably sleeved on the outer periphery of the corresponding mounting shaft 3221. A connecting sleeve bearing 3223 is provided in the connecting sleeve 336, and the connecting sleeve bearing 3223 is sleeved on the outer periphery of the corresponding mounting shaft 3221.

[0037] The turntable device 20 also includes a small disc 40, which is located above the turntable 10 and connected to the turntable drive mechanism 20. The small disc 40 is located between multiple fixture mechanisms 30, and multiple pushing mechanisms 50 are arranged circumferentially on the small disc 40. Each of the multiple pushing mechanisms 50 corresponds to a fixture mechanism 30. In actual application, each pushing mechanism 50 corresponds to a station of the appearance inspection equipment. In this embodiment, there are eight stations and eight fixture mechanisms 30, so there are also eight pushing mechanisms 50. The pushing mechanism 50 is used to push the opening and closing wheel 32 of the fixture mechanism 30 to rotate counterclockwise. Specifically, the pushing mechanism 50 includes a pushing cylinder 51 located at the top of the small disc 40. The output end of the pushing cylinder 51 protrudes from the outer wall of the small disc 40 and is provided with a pushing block 52. The end of the pushing block 52 is provided with a pushing wheel 53. The outer wall of the opening / closing wheel 32 is provided with an approximately L-shaped swing arm 321. The swing arm 321 is located above the support bearing seat 313, and the end of the swing arm 321 protrudes from the outer wall of the support bearing seat 313 and is provided with an inclined surface 3211. The push wheel 53 is used to cooperate with the inclined surface 3211 of the swing arm 321 of the fixture mechanism 30. The push cylinder 51 is used to drive the push block 52 to move towards or away from the fixture mechanism 30, thereby driving the push wheel 53 to move towards or away from the fixture mechanism 30, so that the push wheel 53 can cooperate or disengage from the inclined surface 3211 of the swing arm 321 of the fixture mechanism 30. When the push wheel 53 cooperates with the inclined surface 3211 of the swing arm 321, as the push wheel 53 continues to move, the opening / closing wheel 32 can be driven to rotate counterclockwise through the push wheel 53 and the swing arm 321. A turntable elastic element 34, which is a tension spring, is provided on one side of the swing arm 321 in the clockwise direction. One end of the turntable elastic element 34 is connected to the swing arm 321, and the other end is connected to the top of the support bearing seat 313. When the capacitor 100 on the support shaft 31 is released by the correction wheel 332 of the three straightening arms 232, the turntable elastic element 34 is stretched. When the push wheel 53 separates from the inclined surface 3211 of the swing arm 321, the turntable elastic element 34 resets, thereby driving the opening and closing wheel 32 to rotate clockwise to the initial position via the swing arm 321.

[0038] In this embodiment, the outer wall of the opening and closing wheel 32 is provided with a mounting block 3212, and both ends of the mounting block 3212 are respectively connected to two protrusions 322. The bottom end of the mounting block 3212 is provided with the swing arm 321. The top end of the swing arm 321 and the top end of the support bearing seat 313 are respectively provided with two mounting posts 341, and both ends of the turntable elastic element 34 are respectively connected to the two mounting posts 341.

[0039] Combination Figure 9As shown, the turntable drive mechanism 20 includes a turntable motor 21, a turntable transmission assembly, and a divider 22. In practical applications, the turntable motor 21 is mounted inside the frame 10 via a turntable motor mount 211, and the divider 22 is mounted at the top of the frame 10. The divider 22 has an existing structure. The turntable 10 is located above the divider 22 and is connected to the rotating flange 221 of the divider 22. The small disc 40 is connected to the fixed flange 222 of the divider 22. The turntable 10 has a clearance position for avoiding the fixed flange 222 of the divider 22. The turntable motor 21 is connected to the input shaft of the divider 22 via the turntable transmission assembly. The turntable motor 21 drives the turntable 10 to rotate counterclockwise via the turntable transmission assembly and the divider 22.

[0040] The turntable transmission assembly includes a turntable drive wheel 231, a turntable driven wheel 232, and a turntable timing belt 233 fitted around the outer periphery of the drive wheel 231 and the driven wheel 232. The drive wheel 231 is fitted around the outer periphery of the output end of the turntable motor 21, and the driven wheel 232 is fitted around the outer periphery of the extension shaft of the divider 22. In practical applications, the top of the frame 10 is provided with a clearance hole to avoid the turntable timing belt 233. The turntable motor 21 drives the drive wheel 231 to rotate. Under the action of the driven wheel 232 and the turntable timing belt 233, the input shaft of the divider 22 can be driven to rotate, thereby driving the rotating flange 221 of the divider 22 to rotate.

[0041] The outer periphery of the turntable drive wheel 231, the turntable driven wheel 232, and the turntable timing belt 233 is fitted with a protective cover 234 (see Figure 1 The protective cover 234 is installed on the turntable motor base 211. The protective cover 234 protects the turntable drive wheel 231, the turntable driven wheel 232 and the turntable timing belt 233.

[0042] Combination Figures 10 to 13As shown, a connecting mechanism 60 is provided below the turntable 10. The connecting mechanism 60 includes multiple adsorption shafts 61. Except for the first and last fixture mechanisms 30, the support shafts 31 of the remaining fixture mechanisms 30 correspond one-to-one with the multiple adsorption shafts 61. In this embodiment, there are eight fixture mechanisms 30, so there are six adsorption shafts 61 in the connecting mechanism 60. The adsorption shafts 61 and the corresponding support shafts 31 are arranged vertically opposite each other. The adsorption shafts 61 are located on one side of the connecting support base 68 and can move up and down and rotate relative to the connecting support base 68. In actual application, the connecting support base 68 is located at the top of the frame 10. The adsorption shaft 61 has an inner cavity 611 that extends through its axial direction. The inner cavity 611 is used to communicate with the adsorption cavity 311 of the support shaft 31. The bottom end of the adsorption shaft 61 is provided with a connector 612, which communicates with the inner cavity 611 and is used to connect with a vacuum pump. An upper abutment sleeve 613 is fitted around the outer periphery of the adsorption shaft 61, with a portion of the upper abutment sleeve 613 protruding from the top of the adsorption shaft 61. A support abutment sleeve 314 is fitted around the outer periphery of the support shaft 31, corresponding to the upper abutment sleeve 613 of the adsorption shaft 61. The bottom end of the support abutment sleeve 314 is flush with the bottom end of the support shaft 31 and located below the support bearing seat 313. The support abutment sleeve 314 can move up and down relative to the support shaft 31. A support elastic element 315, which is a compression spring, is provided between the support abutment sleeve 314 and the support bearing seat 313, and is fitted around the outer periphery of the support shaft 31. As the adsorption shaft 61 moves upward, it drives the upper abutment sleeve 613 to move upward as well. When the upper abutment sleeve 613 contacts the corresponding support abutment sleeve 314, its continued movement pushes the support abutment sleeve 314 upward until the top of the adsorption shaft 61 abuts against the bottom of the corresponding support shaft 31. Since the upper abutment sleeve 613 protrudes from the top of the adsorption shaft 61, the support shaft 31 is located within the upper abutment sleeve 613 when it abuts against the bottom of the support shaft 31. Thus, the upper abutment sleeve 613 can limit the support shaft 31. When the support elastic element 315 is compressed, the inner cavity 611 is connected to the adsorption cavity 311 of the corresponding support shaft 31. By using a vacuum pump to evacuate the inner cavity 611 through the connector 612, a vacuum can be evacuated from the adsorption cavity 311 of the corresponding support shaft 31. This allows the corresponding support shaft 31 and the capacitor 100 on the support shaft 31 to be attracted and fixed. During the vacuuming process, the sealing ring 312 at the top of the support shaft 31 can play a sealing role. Then, the adsorption shaft 61 can drive the support shaft 31 and the capacitor 100 on the support shaft 31 to rotate.When the vacuuming device stops evacuating the inner cavity 611 and the adsorption chamber 311 of the corresponding support shaft 31, the adsorption of the corresponding support shaft 31 and the capacitor 100 on the support shaft 31 can be stopped. The adsorption shaft 61 can move downward. During the process of the adsorption shaft 61 moving downward to the initial position, when the upper abutment sleeve 613 separates from the support abutment sleeve 314, under the reset action of the support elastic element 315, the support abutment sleeve 314 can be driven to move downward to the initial position.

[0043] Multiple adsorption shafts 61 are divided into multiple groups, with two adsorption shafts 61 in each group. A rotation drive mechanism 70 and a movement drive mechanism 80 are respectively provided between the two adsorption shafts 61 in each group. The rotation drive mechanism 70 drives the corresponding two adsorption shafts 61 to rotate, and the movement drive mechanism 80 drives the corresponding two adsorption shafts 61 to move upwards. The two adsorption shafts 61 are driven to rotate by one rotation drive mechanism 70 and to move upwards by one movement drive mechanism 80, which saves on power costs.

[0044] The rotary drive mechanism 70 includes a rotary motor 71 and a rotary transmission assembly. In practical applications, the rotary motor 71 is mounted on the top of the frame 10 via a rotary motor base 711. A sliding sleeve 62 is fitted around the outer periphery of the adsorption shaft 61, and a connecting bearing seat 63 is rotatably fitted around the outer periphery of the sliding sleeve 62. The connecting bearing seat 63 is located on one side of the connecting support base 68. The rotary motor 71 is connected to the sliding sleeves 62 of the two corresponding adsorption shafts 61 via the rotary transmission assembly. The rotary motor 71 drives the sliding sleeves 62 of the two corresponding adsorption shafts 61 to rotate via the rotary transmission assembly, thereby driving the two corresponding adsorption shafts 61 to rotate. The rotation of the adsorption shafts 61 drives the upper abutment sleeve 613 and the connector 612 to rotate.

[0045] In this embodiment, the rotational transmission assembly includes a rotating drive wheel 721, two rotating driven wheels 722, and a rotational timing belt 723 sleeved on the outer periphery of the rotating drive wheel 721 and the two rotating driven wheels 722. The rotating drive wheel 721 is sleeved on the outer periphery of the output end of the rotating motor 71, and the two rotating driven wheels 722 are respectively sleeved on the outer periphery of the sliding sleeves 62 of the corresponding two adsorption shafts 61. The rotating motor 71 drives the rotating drive wheel 721 to rotate, thereby driving the sliding sleeves 62 of the corresponding two adsorption shafts 61 to rotate through the two rotating driven wheels 722 and the rotational timing belt 723.

[0046] The moving drive mechanism 80 includes a moving support base 81, a moving cylinder 82, a moving mounting plate 83, and two push rods 84. In practical applications, the moving support base 81 is installed inside the frame 10, and the moving cylinder 82 is mounted on one side of the moving support base 81 via a cylinder seat 821. The moving mounting plate 83 is slidably mounted on one side of the moving support base 81 via a conventional slider and a slide rail that slides in cooperation with the slider, and is located above the moving cylinder 82. The moving mounting plate 83 is connected to the output end of the moving cylinder 82. In this embodiment, a moving block 823 is provided on the side of the moving mounting plate 83 away from the moving support base 81, and the moving block 823 is connected to the output end of the moving cylinder 82. Two movable mounting seats 831 are spaced apart on the side of the movable mounting plate 83 away from the movable support seat 81. The movable cylinder 82 is located between the two movable mounting seats 831. Two push rods 84 are respectively set on the two movable mounting seats 831. In actual application, the top ends of the two push rods 84 extend from the two through holes of the frame. The top ends of the two push rods 84 are respectively equipped with two rollers 841. The two rollers 841 are respectively located below the two corresponding adsorption shafts 61.

[0047] A lower abutment sleeve 614 is fitted around the outer periphery of the adsorption shaft 61. The lower abutment sleeve 614 is located below the sliding sleeve 62, and its bottom end is flush with the bottom end of the adsorption shaft 61. A connecting elastic element 64 is provided between the lower abutment sleeve 614 and the sliding sleeve 62. The connecting elastic element 64 is an elastic sleeve or a compression spring, and it is fitted around the outer periphery of the adsorption shaft 61. The rotation of the adsorption shaft 61 and the sliding sleeve 62 can drive the lower abutment sleeve 614 and the connecting elastic element 64 to rotate. Two rollers 841 are respectively used to cooperate with the bottom ends of the lower abutment sleeves 614 of the corresponding two adsorption shafts 61. The movable cylinder 82 is used to drive the movable mounting plate 83 to move up and down, thereby driving the two push rods 84 to move up and down through the two movable mounting seats 831, which in turn drives the two rollers 841 to move up and down, so that the two rollers 284 respectively engage or disengage with the bottom ends of the lower abutment sleeves 614 of the corresponding two adsorption shafts 61. The rollers 284 are set to form rolling contact with the lower abutment sleeves 614, so that the lower abutment sleeves 614 will not be damaged during the rotation of the adsorption shafts 61.

[0048] In this embodiment, the movable mounting base 831 is provided with mounting holes. Two push rods 84 are respectively installed through the mounting holes of the two movable mounting bases 831 and can move up and down relative to the corresponding movable mounting bases 831. Two movable elastic elements 85, which are compression springs, are respectively sleeved on the outer periphery of the two push rods 84. The two movable elastic elements 85 are respectively located above the two movable mounting bases 831. One end of the two movable elastic elements 85 is connected to the two movable mounting bases 831, and the other end of the two movable elastic elements 85 is connected to the outer wall of the two push rods 84. A buffer block 842 is provided at the bottom end of the push rod 84. The outer diameter of the buffer block 842 is larger than the inner diameter of the mounting hole. The material of the buffer block 842 is, for example, rubber or silicone.

[0049] As the two push rods 84 move upward, when the two rollers 841 engage with the bottom ends of the lower abutment sleeves 614 of the corresponding two adsorption shafts 61, the two push rods 84 continue to move, thereby pushing the lower abutment sleeves 614 of the corresponding two adsorption shafts 61 upward through the two rollers 841. The upward movement of the lower abutment sleeves 614 can drive the adsorption shafts 61 to move upward relative to the sliding sleeves 62. At this time, the connecting elastic element 64 is compressed. When the two rollers 841 separate from the bottom ends of the lower abutment sleeves 614 of the corresponding two adsorption shafts 61, under the reset action of the connecting elastic element 64, the lower abutment sleeves 614 and the adsorption shafts 61 can be driven downward to the initial position. When the two rollers 841 are engaged with the bottom ends of the lower abutment sleeves 614 of the corresponding two adsorption shafts 61, as the two push rods 84 continue to move, the two push rods 84 will move downward under the action of the lower abutment sleeves 614 of the two adsorption shafts 61 pressing the two rollers 841. At this time, the compression of the two movable elastic elements 85 plays a buffering role to avoid damage to the two push rods 84. When the two rollers 841 are separated from the bottom ends of the lower abutment sleeves 614 of the corresponding two adsorption shafts 61, the reset action of the two movable elastic elements 85 can drive the two push rods 84 to move upward to the initial position. During the process of the two push rods 84 moving upward to the initial position, the buffer block 842 at the bottom end of the push rod 84 can play a buffering role for the push rod 84.

[0050] With the above structure, in practical application, taking the first fixture mechanism 30 as an example, the first fixture mechanism 30 corresponds to the first station of the capacitor appearance inspection equipment. First, the push block 52 is driven by the push cylinder 51 corresponding to the first fixture mechanism 30 to move towards the first fixture mechanism 30, so as to push the opening and closing wheel 32 of the first fixture mechanism 30 to rotate in the counterclockwise direction, thereby driving the correction wheel 332 of the three straightening arms 33 to move away from the support shaft 31. This makes it easier for the feeding device at the first station of the capacitor appearance inspection equipment to place the qualified capacitor 100 on the top of the support shaft 31. At this time, the turntable elastic element 34 of the first fixture mechanism 30 is stretched. After the feeding device places the capacitor 100 at the top of the support shaft 31, the pusher 52 is driven by the push cylinder 51 corresponding to the first fixture mechanism 30 to move away from the first fixture mechanism 30 to the initial position. Under the reset action of the turntable elastic element 34 of the first fixture mechanism 30, the opening and closing wheel 32 of the first fixture mechanism 30 can be driven to rotate clockwise, thereby driving the straightening wheels 332 of the three straightening arms 33 to move closer to the support shaft 31, thus clamping the capacitor 100 on the support shaft 31. Then, the turntable drive mechanism 20 drives the turntable 10 to rotate counterclockwise, thereby moving the first fixture mechanism 30 and the capacitor 100 to the position corresponding to the second station. After the appearance defects of the capacitor 100 are photographed and inspected by the inspection device at the second station of the capacitor appearance inspection equipment, the turntable drive mechanism 20 drives the turntable 10 to continue rotating counterclockwise, thereby moving the first fixture mechanism 30 and the capacitor 100 to the position corresponding to the third station.After the appearance defects of capacitor 100 are photographed and inspected by the inspection device at the third station of the capacitor appearance inspection equipment, the turntable 10 is driven by the turntable drive mechanism 20 to continue rotating counterclockwise, so as to move the first fixture mechanism 30 and capacitor 100 to the position corresponding to the fourth station. Then, the adsorption shaft 61 corresponding to the fourth station is driven to move upward so that the top end of the adsorption shaft 61 abuts against the bottom end of the support shaft 31 of the first fixture mechanism 30, and the inner cavity 611 of the adsorption shaft 61 and the adsorption cavity 311 of the support shaft 31 of the first fixture mechanism 30 are evacuated, so as to achieve adsorption and fixation of the support shaft 31 and capacitor 100. Then, the push block 52 is driven by the push cylinder 51 corresponding to the fourth station to move towards the first fixture mechanism 30, so as to push the opening and closing wheel 32 of the first fixture mechanism 30 to rotate counterclockwise, so that the capacitor 100 can be released by the three correction wheels 332 of the first fixture mechanism 30. The turntable elastic element 34 is stretched, and then the adsorption shaft 61 corresponding to the fourth station is driven to rotate, thereby driving the support shaft 31 of the first fixture mechanism 30 and the capacitor 100 to rotate. At the same time, the appearance defects of the capacitor 100 are photographed and detected by the detection device at the fourth station of the capacitor appearance inspection equipment. After the inspection is completed, the adsorption shaft 61 corresponding to the fourth station stops rotating, and the push block 52 is driven to move away from the first fixture mechanism 30 by the push cylinder 51 corresponding to the fourth station. Under the reset action of the turntable elastic element 34, the opening and closing wheel 32 of the first fixture mechanism 30 can be driven to rotate clockwise, so that the capacitor 100 can be clamped by the three correction wheels 332 of the first fixture mechanism 30. Then, the vacuuming of the inner cavity 611 of the adsorption shaft 61 corresponding to the fourth station and the adsorption cavity 311 of the support shaft 31 of the first fixture mechanism 30 is stopped, and the adsorption shaft 61 corresponding to the fourth station is driven to move downward to the initial position.

[0051] Then, the turntable 10 is driven by the turntable drive mechanism 20 to continue rotating counterclockwise, so as to move the first fixture mechanism 30 and the capacitor 100 to the position corresponding to the fifth station. This step is the same as the step when the first fixture mechanism 30 and the capacitor 100 are moved to the position corresponding to the fourth station, and will not be repeated here. In this way, the appearance defects of the capacitor 100 can be photographed and detected by the detection device at the fifth station of the capacitor appearance inspection equipment.

[0052] Then, the turntable 10 is driven by the turntable drive mechanism 20 to continue rotating counterclockwise, so as to move the first fixture mechanism 30 and the capacitor 100 to the position corresponding to the sixth station. This step is the same as the step when the first fixture mechanism 30 and the capacitor 100 are moved to the position corresponding to the fourth station, and will not be repeated here. In this way, the appearance defects of the capacitor 100 can be photographed and detected by the detection device at the sixth station of the capacitor appearance inspection equipment.

[0053] Then, the turntable 10 is driven by the turntable drive mechanism 20 to continue rotating counterclockwise, so as to move the first fixture mechanism 30 and the capacitor 100 to the position corresponding to the seventh station. This step is the same as the step when the first fixture mechanism 30 and the capacitor 100 are moved to the position corresponding to the fourth station, and will not be repeated here. In this way, the appearance defects of the capacitor 100 can be photographed and detected by the detection device at the seventh station of the capacitor appearance inspection equipment.

[0054] Then, the turntable 10 is driven by the turntable drive mechanism 20 to continue rotating counterclockwise, so as to move the first fixture mechanism 30 and the capacitor 100 to the position corresponding to the eighth station. Then, the unloading device at the eighth station of the capacitor appearance inspection equipment clamps the capacitor 100 on the support shaft 31 of the first fixture mechanism 30. Then, the push cylinder 51 corresponding to the eighth station drives the push block 52 to move towards the first fixture mechanism 30, so as to push the opening and closing wheel 32 of the first fixture mechanism 30 to rotate counterclockwise, thereby through the three correction wheels 3 of the first fixture mechanism 30 Capacitor 100 can be released at step 32. At this time, the turntable elastic element 34 is stretched, and the capacitor 100 can be removed from the first fixture mechanism 30 by the unloading device. Then, the push block 52 is driven by the push cylinder 51 corresponding to the eighth station to move away from the first fixture mechanism 30. Under the reset action of the turntable elastic element 34, the opening and closing wheel 32 of the first fixture mechanism 30 can be driven to rotate clockwise, thereby driving the three correction wheels 332 of the first fixture mechanism 30 to move towards the support shaft 31 to return to the initial position. In this way, the first fixture mechanism 30 completes one work cycle. The remaining fixture mechanisms 30 can be moved to the position corresponding to the first station by the turntable 10 and then proceed with the above steps.

[0055] The fixture mechanism 30 of this utility model includes a support shaft 31 and a centering clamping assembly. The support shaft 31 supports the capacitor 100, and the centering clamping assembly clamps the capacitor 100 on the support shaft 31. During the clamping process, the position of the capacitor 100 can be corrected to ensure that the axis of the capacitor 100 is collinear with the axis of the support shaft 31. This allows the capacitor 100 to be positioned at the center of the support shaft 31, ensuring the accuracy of the capacitor 100's position and improving the accuracy and precision of the detection. Simultaneously, the use of a correction wheel 332 to clamp the capacitor 100 avoids scratching it. By adjusting the rotation angle of the opening and closing wheel 32, the distance the correction wheel 332 of the three straightening arms 33 moves closer to or further away from the support shaft 31 can be adjusted, thus adapting to capacitors 100 with different outer diameters and heights, offering good versatility and a wide range of applications. By adjusting the driving force of the cylinder 51, the rotation angle of the opening and closing wheel 32 can be adjusted. The rotation of the opening and closing wheel 32 is achieved using the cylinder 51 and the turntable elastic element 34, requiring only one power source, thus saving power costs. The adsorption chamber 311, adsorption shaft 61, rotation drive mechanism 70, and movement drive mechanism 80, all located on the support shaft 31, can drive the capacitor 100 to rotate. This allows for a more comprehensive inspection of the capacitor 100's appearance defects using the capacitor appearance inspection equipment, improving inspection efficiency. Furthermore, the rotation drive mechanism 70 can drive both adsorption shafts 61 to rotate simultaneously, and the movement drive mechanism 80 can drive both adsorption shafts 61 to move upwards simultaneously, further saving power costs.
