Description

TECHNICAL FIELD

[0001] The present application relates to capacitor production equipment, in particular to a capacitor assembling machine. BACKGROUND

[0002] The capacitor assembling machine is an automatic production equipment for assembling elements, end covers and shells to form capacitor semi-products, and for bundling waists and sealing the capacitor semi-products to form capacitor products, which is mainly used for the automatic production of aluminum electrolytic capacitors.

[0003] Element insertion into the shell is an important step in the capacitor assembling process. When inserting the element into the shell, the existing capacitor assembling machine needs to first use an assembling mold to grab the shell and simultaneously form an enclosure for the element, so that the element can be accurately inserted into the shell through the guide cavity in the assembling mold, thereby avoiding position deviation or axis tilt. After completing the element insertion into the shell, the assembling mold also needs to transport the capacitor semi-product from the assembling device to the waist bundling and sealing device.

[0004] Since the shell needs to be grabbed and the element needs to be enclosed at the same time, the thickness of the assembling mold is large, generally comparable to the total length of the shell and the element, which results in a large weight of the assembling mold, requiring a large driving force when moving and generating a large vibration noise. SUMMARY

[0005] In order to solve the above-mentioned deficiencies of the prior art, the present application provides a capacitor assembling machine which can reduce the driving force required when the assembling mold moves and the vibration noise generated.

[0012] Furthermore, the assembly device includes a turntable mechanism, a top-in mechanism, and a shell-insertion mechanism. The turntable mechanism is used to transport the gripped elements sequentially to the shell-insertion station by rotation. The top-in mechanism and the shell-insertion mechanism are both located at the shell-insertion station. The top-in mechanism is located below the second set of molds and aligned with the first set of molds.

The third mold opening and closing mechanism drives the waist-binding mold to open and close, so that the waist-binding mold can grasp or release the capacitor semi-finished product. The ejection mechanism is located below the waist-binding mold and is used to eject the capacitor finished product inside the waist-binding mold.

[0016] The present invention has the following beneficial effects: The capacitor assembly machine of the present invention adopts a dual-mold structure. The first set of molds is only responsible for surrounding the element, so its position is fixed and corresponds to the shell insertion station. The second set of molds is only responsible for gripping the shell and transporting the capacitor semi-finished product, so its position is movable and driven by the capacitor transfer mechanism to move between the first set of molds and the waist-binding mold. In this way, as long as the total thickness of the first set of molds and the second set of molds is approximately equal to the total length of the shell and the element, the insertion accuracy between the element and the shell can be guaranteed. Moreover, since the first set of molds does not need to move and the weight of the second set of molds is small, the capacitor transfer mechanism only needs to output a small driving force to realize the transfer of the capacitor semi-finished product. The vibration noise generated by the second set of molds during movement is also small. Attached Figure Description

Thus, a feature defined as "first," "second," or "third" may explicitly or implicitly include one or more of that feature. In the description of this invention, "multiple" means two or more, unless otherwise explicitly specified.

[0029] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," "fixing," and "setting," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0030] Example 1 like Figures 1-3 As shown, a capacitor assembly machine includes an assembly device 1 and a waist-sealing device 2. The assembly device 1 is used to assemble a component e, an end cap f, and a casing g to form a capacitor semi-finished product. The waist-sealing device 2 is used to waist-seal the capacitor semi-finished product to form a finished capacitor. The assembly device 1 has a casing insertion station, and the waist-sealing device 2 includes a waist-sealing mold 21. The assembly device 1 includes a first assembly mold 19 and a first mold opening and closing mechanism 1a. The waist-sealing device 2 further includes a second assembly mold 24, a second mold opening and closing mechanism 25, and a capacitor transfer mechanism 26. The first set of upright molds 19 is disposed at the shell insertion station and is used to enclose the element e; the first mold opening and closing mechanism 1a is connected to drive the first set of upright molds 19 to open and close. The second set of vertical molds 24 can move between the first set of vertical molds 19 and the waist-binding mold 21, and is used to grasp the outer shell g and transport the capacitor semi-finished product; the second mold opening and closing mechanism 25 is connected to drive the second set of vertical molds 24 to open and close, and the capacitor transfer mechanism 26 is connected to drive the second set of vertical molds 24 to move; When the second set of upright molds 24 moves to the first set of upright molds 19, it is located below the first set of upright molds 19 and aligned with the first set of upright molds 19. When the second set of upright molds 24 moves to the waist-cinching mold 21, it is located above the waist-cinching mold 21 and aligned with the waist-cinching mold 21.

[0031] The capacitor assembly machine of the present invention adopts a dual-mold structure. The first mold 19 is only responsible for enclosing the element e, so its position is fixed and corresponds to the shell insertion station. The second mold 24 is only responsible for gripping the shell g and transporting the capacitor semi-finished product, so its position is movable and driven by the capacitor transfer mechanism 26 to move between the first mold 19 and the waist-binding mold 21. In this way, as long as the total thickness of the first mold 19 and the second mold 24 is approximately equal to the total length of the shell g and the element e, the insertion accuracy between the element e and the shell g can be guaranteed. Moreover, since the first mold 19 does not need to move, the second mold 24 is relatively light, and the capacitor transfer mechanism 26 only needs to output a small driving force to realize the transfer of the capacitor semi-finished product. The vibration noise generated by the second mold 24 during movement is also relatively small.

[0032] Preferably, the thickness of the second set of molds 24 is less than the thickness of the first set of molds 19. The thickness referred to here is the dimension of the first set of molds 19 and the second set of molds 24 along the axial direction (or length direction) of the outer shell g.

[0033] After the first set of molds 19 is closed, it has a guide cavity that runs vertically through it; after the second set of molds 24 is closed, it has a first grasping cavity that runs vertically through it; the alignment of the second set of molds 24 and the first set of molds 19 means that the guide cavity and the first grasping cavity are aligned and connected vertically, so that the element e can enter the first grasping cavity along the guide cavity and then be inserted into the outer shell g.

[0034] Preferably, the guiding cavity is funnel-shaped, with a larger upper inlet and a smaller lower outlet, and the diameter between the lower outlet of the guiding cavity and the upper inlet of the first grasping cavity is the same. The shape of the first grasping cavity is adapted to the outer shape of the outer shell g, and is generally cylindrical or multi-faceted cylindrical.

[0035] The waist-binding mold 21 has a second gripping cavity extending vertically inside; the alignment of the second set of vertical molds 24 with the waist-binding mold 21 means that the first gripping cavity and the second gripping cavity are vertically aligned and connected, so that the capacitor semi-finished product can enter the second gripping cavity along the first gripping cavity.

[0036] Preferably, the second gripping cavity has the same diameter as the first gripping cavity. The shape of the second gripping cavity is adapted to the outer shape of the outer shell g, and is generally cylindrical or multi-faceted cylindrical.

[0037] like Figure 4As shown, the capacitor assembly machine further includes a drive device 3, which includes a drive source 31, a first transmission spindle 32, a second transmission spindle 33, a third transmission spindle 34, a first transmission gear 35, a second transmission gear 36, a third transmission gear 37, a transmission belt 38, a transfer cam 39, a first opening / closing cam 3a, and a second opening / closing cam 3b. The first transmission spindle 32, the second transmission spindle 33, and the third transmission spindle 34 are all horizontally arranged. The drive source 31 drives the first transmission spindle 32 to rotate. The first transmission gear 35 is coaxially arranged on the first transmission spindle 32, and the second transmission gear 36 is coaxially arranged on the second transmission spindle 33. The third transmission gear 38 is a drive source 31, a first transmission spindle 32, a second transmission spindle 33, a third transmission spindle 34, a first transmission gear 35, a second transmission gear 36, a third transmission gear 37, a transmission belt 38, a transfer cam 39, a first opening / closing cam 3a, and a second opening / closing cam 3b. The first transmission spindle 32, the second transmission spindle 33, and the third transmission gear 39 are all horizontally arranged. The drive source 31 drives the first transmission spindle 32 to rotate. The first transmission gear 35 is coaxially arranged on the first transmission spindle 32, and the second transmission gear 36 is coaxially arranged on the second transmission spindle 33. The third transmission gear 39 is a drive source 31, a first transmission spindle 32, a second transmission spindle 33, a third transmission spindle 34, a first transmission gear 35, a second transmission gear 36, a third transmission gear 37, a third transmission gear 38, a third transmission gear 39, a third transmission gear 30, a third transmission gear The moving gear 37 is coaxially mounted on the third transmission main shaft 34, and the transmission belt 38 is sleeved and connected between the first transmission gear 35, the second transmission gear 36, and the third transmission gear 37; the transfer cam 39 is coaxially mounted on the first transmission main shaft 32 and is connected to drive the capacitor transfer mechanism 26 to move the second set of vertical molds 24; the first opening and closing cam 3a is coaxially mounted on the second transmission main shaft 33 and is connected to drive the first mold opening and closing mechanism 1a to open and close the first set of vertical molds 19; the second opening and closing cam 3b is coaxially mounted on the third transmission main shaft 34 and is connected to drive the second mold opening and closing mechanism 25 to open and close the second set of vertical molds 24.

[0038] The capacitor assembly machine of the present invention only needs to use a single drive source 31 to drive the first transmission main shaft 32 to rotate, and drive the second transmission main shaft 33 and the third transmission main shaft 34 to rotate synchronously through the transmission structure composed of the first transmission gear 35, the second transmission gear 36, the third transmission gear 37 and the transmission belt 38. Thus, through the synchronous rotation of the transfer cam 39, the first opening and closing cam 3a and the second opening and closing cam 3b, the capacitor transfer mechanism 26, the first mold opening and closing mechanism 1a and the second mold opening and closing mechanism 25 are driven to perform corresponding driving actions, thereby reducing the driving cost. Since a single drive source 31 is used, the capacitor assembly machine of the present invention can, by reasonably designing the rotation phase difference between the transfer cam 39, the first opening and closing cam 3a and the second opening and closing cam 3b, enable the capacitor transfer mechanism 26, the first mold opening and closing mechanism 1a and the second mold opening and closing mechanism 25 to perform corresponding driving actions at different time phases.

[0039] In this embodiment, the drive source 31 is a drive motor, but other conventional rotary drives can also be used.

[0040] like Figure 5As shown, the first mold opening and closing mechanism 1a includes a first swing arm 1a1, a first swing arm seat 1a2, a first connecting rod 1a3, a sector gear 1a4, a connecting fixed seat 1a5, a first rotating shaft 1a6, a first opening and closing gear 1a7, and a second opening and closing gear 1a8. The sector gear 1a4 and the first rotating shaft 1a6 are rotatably mounted on the connecting fixed seat 1a5. One end of the first swing arm 1a1 is rotatably connected to the first swing arm seat 1a2, and the other end is rotatably connected to the first connecting rod 1a3. The middle part is connected to the first swing arm seat 1a2. The first opening and closing cam 3a is in contact with the first connecting rod 1a3; one end of the first connecting rod 1a3 is rotatably connected to the non-sector end of the sector gear 1a4, and the other end is rotatably connected to the first swing arm 1a1; the first rotating shaft 1a6 is vertically arranged, the first opening and closing gear 1a7 is coaxially arranged at the lower end of the first rotating shaft 1a6 and meshes with the sector teeth of the sector gear 1a4, and the second opening and closing gear 1a8 is coaxially arranged at the upper end of the first swing shaft and meshes with the first set of vertical molds 19.

[0041] When the first opening and closing cam 3a rotates, its protruding and non-protruding parts sequentially contact the first swing arm 1a1, thereby pushing the first swing arm 1a1 to swing back and forth, and sequentially driving the first set of vertical molds 19 to open and close through the first connecting rod 1a3, the first sector gear 1a4, the first transmission gear 35, the first rotating shaft 1a6 and the second transmission gear 36; when the protruding part of the first opening and closing cam 3a contacts the first swing arm 1a1, the first set of vertical molds 19 is in the open state, and when the non-protruding part of the first opening and closing cam 3a contacts the first swing arm 1a1, the first set of vertical molds 19 is in the closed state.

[0042] To ensure that the first opening / closing cam 3a and the first rocker arm 1a1 always remain in contact, a corresponding cam groove can be made on the side of the first opening / closing cam 3a, and the middle of the first rocker arm 1a1 can be embedded into the cam groove of the first opening / closing cam 3a. Alternatively, a corresponding spring can be provided so that the tension of the spring keeps the middle of the first rocker arm 1a1 always in contact with the outer peripheral surface of the first opening / closing cam 3a.

[0043] like Figure 6As shown, the first set of vertical molds 19 includes a first mold base 191, a fixed bushing 192, and two first set of vertical arms 193. The fixed bushing 192 is fixedly connected between the first mold base 191 and the connecting fixed seat 1a5. The first rotating shaft 1a6 passes through the fixed bushing 192. The two first set of vertical arms 193 are rotatably disposed on the first mold base 191. One end of each arm is provided with a first groove, and the other end is provided with a first gear part 194 that meshes with each other. The first gear part 194 of one of the first set of vertical arms 193 meshes with the second opening and closing gear 1a8. When the two first grooves are closed, they can form the guide cavity 190.

[0044] The first mold opening and closing mechanism 1a can drive the two first set of upright arms 193 to swing in opposite directions through the rotation of the second opening and closing gear 1a8 and the transmission between the two first gear parts 194. When the second opening and closing gear 1a8 rotates around the first circumference, the two first resistance arms swing towards each other and thus close each other. When the second opening and closing gear 1a8 rotates around the second circumference, the two first resistance arms swing away from each other and thus open each other.

[0045] like Figure 7 and 8 As shown, the second mold opening and closing mechanism 25 includes a second swing arm 251, a second swing arm seat 252, a second connecting rod 253, a first connecting block 254, a second rotating shaft 256, and a third opening and closing cam 257. The second rotating shaft 256 is vertically arranged, and the third opening and closing cam 257 is coaxially arranged at the upper end of the second rotating shaft 256 and connected to the second set of vertical molds 24 for transmission. The first connecting block 254 is fixedly arranged at the lower end of the second rotating shaft 256. The middle of the second swing arm 251 is rotatably connected to the second swing arm seat 252, one end of which is in contact with the second opening and closing cam 3b, and the other end of which is rotatably connected to the second connecting rod 253. One end of the second connecting rod 253 is rotatably connected to the first connecting block 254, and the other end of which is rotatably connected to the second swing arm 251.

[0046] When the second opening / closing cam 3b rotates, its protruding and non-protruding parts sequentially contact the second swing arm 251, thereby pushing the second swing arm 251 to swing back and forth. This, in turn, drives the third opening / closing cam 257 to rotate back and forth via the second connecting rod 253, the first connecting seat, and the second rotating shaft 256, so that the protruding and non-protruding parts of the third opening / closing cam 257 also sequentially contact the second set of vertical molds 24, thereby driving the second set of vertical molds 24 to open and close. When the protruding part of the second opening / closing cam 3b contacts the second swing arm 251, the third opening / closing cam 257 rotates until its protruding part contacts the second set of vertical molds 24, and the second set of vertical molds 24 is in an open state. When the non-protruding part of the second opening / closing cam 3b contacts the second swing arm 251, the third opening / closing cam 257 rotates until its non-protruding part contacts the second set of vertical molds 24, and the second set of vertical molds 24 is in a closed state.

[0047] To ensure that the second opening / closing cam 3b and the second rocker arm 251 always remain in contact, a corresponding cam groove can be made on the side of the second opening / closing cam 3b, and one end of the second rocker arm 251 can be embedded in the cam groove of the second opening / closing cam 3b. Alternatively, a corresponding spring can be provided so that the tension of the spring keeps one end of the second rocker arm 251 always in contact with the outer circumferential surface of the second opening / closing cam 3b.

[0048] In this embodiment, the second swing arm 251 is an L-shaped swing arm.

[0049] like Figure 9 As shown, the second set of vertical molds 24 includes a second mold base 241 and two second set of vertical arms 242. The two second set of vertical arms 242 are rotatably mounted on the second mold base 241. One end of each arm is provided with a second groove, and the other end is provided with a second gear part 243 that meshes with it. One of the second set of vertical arms 242 is provided with a toggle part 244 that contacts and connects with the third opening and closing cam 257. When the two second grooves are closed, they can form the first gripping cavity 240.

[0050] The second mold opening and closing mechanism 25 can drive the two second sets of upright arms 242 to swing in opposite directions through the rotation of the third opening and closing cam 257 and the transmission between the two second gear parts 243. When the protruding part of the third opening and closing cam 257 contacts the actuating part 244 of the second set of upright arms 242, the two sets of upright arms 242 swing towards each other and thus open each other. When the non-protruding part of the third opening and closing cam 257 contacts the actuating part 244 of the second set of upright arms 242, the two sets of upright arms 242 swing towards each other and thus close each other.

[0051] In some examples, the second set of molds 24 further includes a toggle lever 258, which is located between the third opening and closing cam 257 and the toggle part 244. One end of the toggle lever 258 is rotatably disposed, and the other end is in contact with the toggle part 244. The middle part is in contact with the third opening and closing cam 257.

[0052] When the third opening and closing cam 257 rotates, its protruding part and non-protruding part successively contact the actuating lever 258, thereby driving the reciprocating swing. When the actuating lever 258 swings, it actuates the actuating part 244 of the second set of vertical molds 24, thereby driving the two second sets of vertical arms 242 to swing in the opposite direction.

[0053] To ensure that the third opening / closing cam 257 always maintains contact with the middle of the actuating part 244 or actuating lever 258 of the second set of upright arms 242, a corresponding cam groove can be formed on the side of the third opening / closing cam 257, and the middle of the actuating part 244 or actuating lever 258 of the second set of upright arms 242 can be embedded in the cam groove of the third opening / closing cam 257. Alternatively, a corresponding spring can be provided so that the tension of the spring keeps the middle of the actuating part 244 or actuating lever 258 of the second set of upright arms 242 always in contact with the outer peripheral surface of the third opening / closing cam 257.

[0054] like Figure 7 and 8 As shown, the capacitor transfer mechanism 26 includes a third swing arm 261, a third swing arm seat 262, a third connecting rod 263, a second connecting block 264, a rotating bushing 265, and a transfer rotating seat 266. The second set of vertical molds 24 is fixedly mounted on the transfer rotating seat 266. The middle of the third swing arm 261 is rotatably connected to the third swing arm seat 262, one end of which is in contact with the transfer cam 39, and the other end of which is rotatably connected to the third connecting rod 263. The rotating bushing 265 is sleeved outside the second rotating shaft 25, its upper end is fixedly connected to the transfer rotating seat 266, and its lower end is fixedly connected to the second connecting block 264. One end of the third connecting rod 263 is rotatably connected to the second connecting block 264, and the other end of which is rotatably connected to the third swing arm 261.

[0055] When the transfer cam 39 rotates, its protruding and non-protruding parts sequentially contact the third swing arm 261, thereby pushing the third swing arm 261 to swing back and forth. It then drives the transfer rotating seat 266 to rotate back and forth through the third connecting rod 263, the second connecting block 264, and the rotating bushing 265, thereby driving the second set of vertical molds 24 to move between the first set of vertical molds 19 and the waist-binding mold 21. When the protruding part of the transfer cam 39 contacts the third swing arm 261, the second set of vertical molds 24 moves above the waist-binding mold 21. When the non-protruding part of the transfer cam 39 contacts the third swing arm 261, the second set of vertical molds 24 moves below the first set of vertical molds 19.

[0056] To ensure that the transfer cam 39 and the third swing arm 261 always remain in contact, a corresponding cam groove can be formed on the side of the transfer cam 39, and one end of the third swing arm 261 can be embedded in the cam groove of the transfer cam 39. Alternatively, a corresponding spring can be provided so that the tension of the spring keeps one end of the third swing arm 261 always in contact with the outer peripheral surface of the transfer cam 39.

[0057] If the toggle lever 258 is required, the toggle lever 258 can be rotatably mounted on the transfer rotating seat 266 or the second mold base 241.

[0058] In this embodiment, the third swing arm 261 is also an L-shaped swing arm.

[0059] like Figures 1-3 As shown, the assembly device 1 includes a turntable mechanism 11, an inserting mechanism 17, and a shell insertion mechanism 18. The turntable mechanism 11 is used to transport each element e to the shell insertion station in sequence by rotating. The inserting mechanism 17 and the shell insertion mechanism 18 are both located at the shell insertion station. The inserting mechanism 17 is located below the second assembly mold 24 and aligned with the first assembly 19. The inserting mechanism 17 is used to insert the shell g into the second assembly mold 24, and the shell insertion mechanism 18 is used to insert the element e into the shell g.

[0060] The working steps of the capacitor assembly machine during installation are as follows: After initialization is completed, the first mold opening and closing mechanism 1a and the second mold opening and closing mechanism 25 respectively drive the first set of upright molds 19 and the second set of upright molds 24 to open. The capacitor transfer mechanism 26 drives the second set of vertical molds 24 to move below the first set of vertical molds 19 and align with the first set of vertical molds 19. The turntable mechanism 11 transports one of the gripped elements e to the shell insertion station by rotation. The ejection mechanism 17 ejects the shell g upward into the second set of vertical molds 24. The first mold opening and closing mechanism 1a and the second mold opening and closing mechanism 25 respectively drive the first set of vertical molds 19 and the second set of vertical molds 24 to close, so that the first set of vertical molds 19 surrounds the element e and the second set of vertical molds 24 grips the shell g. The insertion mechanism 18 pushes the element e from the first set of vertical molds 19 into the second set of vertical molds 24, so that the element e is inserted into the outer shell g, forming the capacitor semi-finished product; The first mold opening and closing mechanism 1a drives the first set of upright molds 19 to open, the capacitor transfer mechanism 26 drives the second set of upright molds 24 to move above the waist-binding mold 21 and align with the waist-binding mold 21, and the second mold opening and closing mechanism 25 drives the second set of upright molds 24 to open, so that the capacitor semi-finished product falls into the waist-binding mold 21 under the action of gravity.

[0061] Preferably, the second transmission spindle 33 of the drive device 3 is also connected to the turntable mechanism 11 to drive the turntable mechanism 11 to rotate.

[0062] Specifically, such as Figure 5 As shown, the turntable mechanism 11 includes a rotating disk 111, a cam divider 112, a rotary output shaft 113, and a plurality of assembly grippers 114. Each assembly gripper 114 is evenly spaced on the circumference of the rotating disk 111. The cam divider 112 has an input end and an output end. The second transmission main shaft 33 is connected to the input end of the cam divider 112, and the rotary output shaft 113 is fixedly connected between the output end of the cam divider 112 and the rotating disk 111.

[0063] The cam divider 112 utilizes its internal cam structure to convert the continuous rotation of the second transmission main shaft 33 into the intermittent rotation of the rotary output shaft 113, thereby driving the rotating disk 111 to rotate intermittently, so as to sequentially transport the elements e gripped by each assembly clamp 114 to the shelling station for the shelling process. Furthermore, since the opening and closing of the first set of molds 19 and the rotation of the rotating disk 111 are both driven by the second transmission main shaft 33, the capacitor assembly machine of the present invention can, through reasonable design of the rotational phase difference between the cam divider 112 and the first opening / closing cam 3a, ensure that the first set of molds 19 opens relatively before the rotating disk 111 rotates, and closes relatively after the rotating disk 111 stops rotating.

[0064] Preferably, the first swing arm seat 1a2 of the first mold opening and closing mechanism 1a is fixedly mounted on the cam divider 112.

[0065] In this embodiment, the top-insertion mechanism 17 and the shell insertion mechanism 18 are existing mechanisms of capacitor assembly machines in the art, so their structures will not be described in detail.

[0066] Preferred, such as Figure 1 As shown, the turntable mechanism 11 is further provided with an end cap feeding station, a pin insertion station, a pin pulling station, a pin separating station, and a detection station in its circumferential direction at the front edge of the shell insertion station. The assembly device 1 also includes an end cap feeding mechanism 12, a pin insertion mechanism 13, a pin pulling mechanism 14, a pin separating mechanism 15, a detection mechanism 16, a component feeding mechanism 1b, and a shell feeding mechanism 1c. The end cap feeding mechanism 12 is located at the end cap feeding station and is used to feed the end cap f onto the turntable mechanism 11. The pin insertion mechanism 13 is located at the pin insertion station and is used to insert the two pins of the component e into the shell. The two pin holes of the end cap f are located in the following positions: the pull-pin mechanism 14 is located at the pull-pin station and is used to straighten the two pins of the element e; the split-pin mechanism 15 is located at the split-pin station and is used to separate the two pins of the element e; the detection mechanism 16 is located at the detection station and is used to detect the two pins of the element e; the element feeding mechanism 1b is connected to the pin insertion mechanism 13 to feed the element e onto the pin insertion mechanism 13; the outer shell feeding mechanism 1c is connected to the top-in mechanism 17 to feed the outer shell g onto the top-in mechanism 17.

[0067] like Figure 3As shown, the assembly gripper 114 is provided with a first gripping part 114a and a second gripping part 114b. The first gripping part 114a is used to grip the end cap f, and the second gripping part 114b is used to grip the two pins of the element e. The first gripping part 114a is located above the second gripping part, so that the two pins of the element e are gripped only after they are inserted into the two pin holes of the end cap f.

[0068] In this embodiment, the end cap feeding mechanism 12, the insertion mechanism 13, the pulling mechanism 14, the splitting mechanism 15, and the detection mechanism 16 are all existing mechanisms of capacitor assembly machines in the art, so their structures will not be described in detail.

[0069] Preferred, such as Figure 1 , 7 As shown in Figure 8, the waist-binding and sealing device 2 further includes a waist-binding mechanism 22, a sealing mechanism 23, a third mold opening and closing mechanism 27, and an ejection mechanism 28. The waist-binding mechanism 22 and the sealing mechanism 23 are both located next to the waist-binding mold 21. The waist-binding mechanism 22 is used to bind the capacitor semi-finished product inside the waist-binding mold 21, and the sealing mechanism 23 is used to seal the capacitor semi-finished product inside the waist-binding mold 21. The third mold opening and closing mechanism 27 drives the waist-binding mold 21 to open and close, so that the waist-binding mold 21 can grasp or release the capacitor semi-finished product. The ejection mechanism 28 is located below the waist-binding mold 21 and is used to eject the capacitor finished product inside the waist-binding mold 21.

[0070] The third mold opening and closing mechanism 27 can drive the waist-binding mold 21 to open or close relative to each other to adjust the diameter of the second gripping cavity. When the waist-binding mold 21 is open relative to each other, the diameter of the second gripping cavity is larger than the diameter of the first gripping cavity 240, so as to facilitate the falling in of the capacitor semi-finished product and the ejection of the capacitor finished product. When the waist-binding mold 21 is closed relative to each other, the diameter of the second gripping cavity is equal to the diameter of the first gripping cavity 240, so as to facilitate the waist-binding mechanism 22 and the sealing mechanism 23 to waist and seal the capacitor semi-finished product respectively.

[0071] In this embodiment, the waist-binding mechanism 22, the sealing mechanism 23, the third mold opening and closing mechanism 27, and the ejection mechanism 28 are all existing mechanisms of capacitor assembly machines in the art, so their structures will not be described in detail.

[0072] The capacitor assembly machine includes a first workbench 4 and a second workbench 5, with the second workbench 5 disposed on the first workbench 4; the assembly device 1 is disposed on the first workbench 4, and the waist-sealing device 2 is disposed on the second workbench 5; and preferably, the connecting fixing seat 1a5 of the first mold opening and closing mechanism 1a is fixedly disposed on the second workbench 5.

[0073] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the embodiments of the present invention and not to limit them. Although the embodiments of the present invention have been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the technical solutions of the embodiments of the present invention, and these modifications or equivalent substitutions cannot cause the modified technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
