Description
Technical Field
The present disclosure relates to the field of capacitors, and more particularly to an injection molding module for a capacitor.
Background
At present, the capacitor (such as but not limited to a super capacitor) has shorter use time due to leakage of electrolyte, so that an adhesive injection process is added on the basis of the original process, and the adhesive adopts AB epoxy resin adhesive to ensure no leakage of the electrolyte and ensure the use time of the capacitor. At present, glue injection of a capacitor is divided into two modes of full-manual glue injection operation and semi-automatic glue injection operation.
The operation process of the full-manual glue injection operation is as follows: manually straightening pins, manually placing in a jig tray, manually pumping A glue by using a syringe, manually pumping B glue by using a syringe, manually injecting AB glue into a capacitor according to a ratio of 2:1, and curing in an oven.
The operation process of the semi-automatic glue injection operation is as follows: manually straightening pins (also called leads), manually placing in a jig tray, a gantry triaxial glue injection machine, and curing in an oven.
That is, the current capacitor glue injection operation does not realize the full-automatic operations of capacitor feeding, lead straightening and jig in-tray glue injection. This results in a lot of manual use and low work efficiency.
Further, for the capacitor feeding part, the published chinese patent application CN209493031U issued in the year 10, month 15 in 2019 discloses a lead monolithic capacitor discharging device, and the working principle is that: the monolithic capacitor arranging device is characterized in that when capacitors are arranged, the capacitors are poured into the spiral sieve hopper, the vibrator drives the spiral sieve hopper to vibrate, the capacitors enter the material discharge groove from the discharge hole on the side face of the spiral sieve hopper after rotating along with the spiral track inside the spiral sieve hopper, and the capacitor taking and placing mechanism sequentially takes and places the capacitors into the capacitor placing groove inside the charging track bracket, so that the arrangement of the capacitors is completed. In this patent document, the capacitor does not directly fall from the material discharge slot into the capacitor placement slot in the charging rail holder, but is operated by means of a capacitor pick-and-place mechanism, so that further arrangement movement charging from the capacitor placement slot is not possible in this patent document. In addition, since the loading rail bracket is stationary, remote loading cannot be realized to accommodate the needs of continuous operations of subsequent processes (such as wire straightening and glue injection).
Further, for the straight part of the pin, china patent application publication No. CN202839319U, which is issued in the publication No. 27 of 03 in 2013, discloses an aluminum electrolytic capacitor jacket stripping machine, the mountain-shaped fork straightening lead device is used for straightening and separating the leads, but the mountain-shaped fork straightening lead device can separate two leads and straighten the leads to a certain degree, but the straightening effect of the mountain-shaped fork straightening lead device still needs to be improved.
Further, to the injecting glue part, adopt the longmen triaxial injecting glue machine of above-mentioned semi-automatic operation, still make the condenser in advance with the pin gesture location in the tool dish up, at this moment, injecting glue process needs the location condenser, and one kind adopts manual positioning, and another kind is with the condenser insert in the check of tool dish, this location inconvenient when leading to the injecting glue of condenser. In addition, although pins can be avoided in the injection operation of the gantry triaxial injection machine, if the operation is not proper, the risk of collision with pins still exists.
Disclosure of Invention
In view of the problems in the background art, an object of the present disclosure is to provide an injection molding module for a capacitor, which can eliminate the risk of collision of the capacitor with the leads of the capacitor during the injection of the capacitor.
Therefore, the glue injection module for the capacitor comprises a jig plate and a glue injection device; the glue injection device is used for injecting glue and sealing the top of the extending lead of the capacitor shell on the jig disc; the glue injection device comprises a lead guiding mechanism for guiding the lead therein.
The beneficial effects of the present disclosure are as follows: compared with a gantry triaxial glue injection machine in the background art, the risk of collision with leads of the capacitor during glue injection of the capacitor can be avoided.

Detailed Description
The drawings illustrate embodiments of the present disclosure, and it is to be understood that the disclosed embodiments are merely examples of the disclosure that may be embodied in various forms and that, therefore, specific details disclosed herein are not to be interpreted as limiting, but merely as a basis for the claims and as a representative basis for teaching one skilled in the art to variously practice the disclosure.
Referring to fig. 1 and 29, a capacitor glue injection apparatus 1000 according to the present disclosure includes a feeding device 1, a lead straightening device 2, a turnover feeding device 4, a jig tray 5, and a glue injection device 6. The lead straightening module comprises a lead straightening device. The lead straightening module can further comprise a turnover feeding device. The glue injection module comprises a jig disc 5 and a glue injection device 6. Namely, the capacitor glue injection device 1000 of the present disclosure includes a feeding device 1, a lead straightening module, and a glue injection module.
The feeder 1 is used for accommodating a plurality of capacitors 2000 with leads 2001 and feeding the capacitors 2000 with leads 2001 to the lead straightening device 2 in such a manner that the leads 2001 are downward and the capacitors 2000 are arranged in a single row. The lead straightening device 2 straightens the downward lead 2001 of each capacitor 2000. The turn-over feeding device 4 is used for turning over each capacitor 2000 with the leads 2001 straightened up into the leads 2001 up and for conveying onto the jig tray 5. The glue injection device 6 is used for performing glue injection sealing on the top portion of the lead wire 2001 of the case 2002 of the capacitor 2000 conveyed to the jig tray 5 (i.e., performing glue injection sealing on the top portion of the lead wire 2001 of the case 2002 of the capacitor 2000 on the jig tray 5).
In the capacitor glue injection apparatus 1000 according to the present disclosure, full-automatic operations of feeding, straightening of the leads 2001 of each capacitor 2000 and injection of glue in the jig tray 5 are realized by feeding the capacitors 2000 to the lead straightening device 2 in such a manner that the leads 2001 are directed downward and arranged in a single row, straightening the downward leads 2001 of each capacitor 2000 by the lead straightening device 2, turning each capacitor 2000 straightened by the lead 2001 upward by the turning feeding device 4 and conveying the same to the jig tray 5, and sealing by the glue injection device 6.
As shown in fig. 2 to 9 in combination with fig. 1, in one embodiment, the feeding device 1 includes a vibration plate feeding mechanism 10, an inversion mechanism 11, and a linear vibration feeding mechanism 12. The vibrating tray feeding mechanism 10 is configured to hold a plurality of capacitors 2000 with leads 2001 and sequentially feed the capacitors 2000 to the inverting mechanism 11 in such a manner that the capacitors 2000 with leads 2001 are spirally moved from bottom to top by repeatedly magnetically attracting and cutting off the capacitors 2000 with leads 2001 to form vibrations. The inverting mechanism 11 is configured to receive the capacitor 2000 supplied from the vibration disk feeding mechanism 10, invert the capacitor 2000 so that the leads 2001 are arranged in a single row downward, and the capacitor 2000 with the leads 2001 arranged in a single row downward is linearly advanced by the capacitor 2000 upstream of the supply of the vibration disk feeding mechanism 10. The linear vibration feeding mechanism 12 receives the capacitor 2000 from the inverting mechanism 11 and holds the capacitor 2000 to supply the capacitor 2000 to the lead straightening device 2 (i.e., downstream) in a linear manner in a single-row arrangement in which the leads 2001 face downward. Compared with the form of the capacitor picking and placing mechanism in the prior art, in the feeding device 1 disclosed by the disclosure, the arrangement motion feeding of the capacitor 2000 can be realized through the cooperation of the vibrating plate feeding mechanism 10, the inverted mechanism 11 and the linear vibration feeding mechanism 12, and the capacitor 2000 can be used for long-distance feeding of the capacitor 2000 so as to adapt to the requirement of continuous operation of subsequent procedures (namely wire straightening and glue injection in the disclosure).
As shown in fig. 2 and 4A, 4B, in one example, the vibrating tray feeding mechanism 10 includes a chassis 100, a cylinder 101, a carrier tray 102, an upper spiral track 103, a first electromagnet 104, a first armature 105, four first leaf springs 106, and an outer spiral track 107.
The chassis 100 is stationary. The cylinder 101 is fixed to the chassis 100. The carrier plate 102 is movably accommodated in the cylinder 101, and the carrier plate 102 is used for carrying a plurality of capacitors 2000 with leads 2001, wherein the housing 2002 is non-magnetic (for example, the housing 2002 is an aluminum case) and the leads 2001 are magnetic (for example, iron leads). The upper spiral track 103 is movably accommodated in the cylinder 101, the upper spiral track 103 spirals from bottom to top, and a starting section of the upper spiral track 103 is fixedly connected to the upper surface of the carrying tray 102. The first electromagnet 104 is accommodated in the cylinder 101, located below the carrier plate 102, and fixed to the chassis 100. The first armature 105 is accommodated in the cylinder 101, is located below the carrier plate 102, and is fixedly connected to the carrier plate 102, and when the first electromagnet 104 is powered on or off (power supply is not shown), the first armature 105 and the first electromagnet 104 are magnetically attracted and disconnected at a fixed frequency, so that the upper spiral track 103 and the carrier plate 102 vibrate in the up-down direction D1. The four first leaf springs 106 are disposed at 90 degree intervals in parallel to each other in pairs, the four first leaf springs 106 are inclined with respect to the axis of the carrier plate 102 and are capable of repeated elastic deformation and elastic recovery with the first armature 105 forming magnetic attraction and disconnection of a fixed frequency with the first electromagnet 104, so that the upper spiral rail 103 and the carrier plate 102 form a torsional vibration around the axis of the carrier plate 102, which, together with the vibration in the up-down direction D1, advances the capacitor 2000 with the lead 2001 on the carrier plate 102 from the carrier plate 102 along the upper spiral rail 103 and supplies the capacitor 2000 to the outer spiral rail 107. An outer spiral rail 107 is provided on the top of the cylinder 101 and is fixed together with the cylinder 101, the outer spiral rail 107 spirals from outside around the cylinder 101, the outer spiral rail 107 for receiving the capacitors 2000 from the upper spiral rail 103 and causing the received capacitors 2000 to sequentially abut against and travel by inertial force coming out of the upper spiral rail 103 to sequentially supply the capacitors 2000 to the inverting mechanism 11. In the figure, the cylinder 101 radially and circumferentially circumscribes the upper helical track 103. In addition, the structure constituted by the chassis 100, the cylinder 101, the carrier plate 102, the upper spiral rail 103, the first electromagnet 104, the first armature 105, the plurality of first leaf springs 106, and the outer spiral rail 107 may be realized by a commercially available vibration plate loader manufactured and sold by, for example, the eastern guan gold standard electronic technology company.
As shown in fig. 2, 4A and 4B, a notch 101a is provided at the top of the cylinder 101; the vibration disk feeding mechanism 10 further includes an engagement piece 108, the engagement piece 108 being connected to the bottom of the notch 101a and the inner wall of the cylinder 101, the engagement piece 108 being for interfacing with the top end of the upper spiral rail 103 to receive and support the capacitor 2000 fed out of the upper spiral rail 103 and to feed the received capacitor 2000 toward the outer spiral rail 107.

The receiving seat 420 is provided with a chute 420a and a gap 420b transversely communicated with the chute 420a, the chute 420a is used for accommodating the capacitor 2000 and the pushing block 421 which are conveyed by the clamping mechanism 40, and the gap 420b is in an elongated shape. The push block 421 can slide in the chute 420 a. One end of the connecting rod 422 is fixedly connected to one end of the rack 412, and the other end of the connecting rod 422 passes through the material receiving seat 420 through the gap 420b and is fixedly connected to the pushing block 421, so that the connecting rod 422 moves along with the linear reciprocating motion of the rack 412 to drive the pushing block 421 to reciprocate in the chute 420 a. In operation, the method comprises the following steps: when the rack 412 moves towards the direction of the lead straightening device 2, the turnover mechanism 41 turns the clamping mechanism 40 towards the pushing mechanism 42, the rack 412 drives the connecting rod 422 and the pushing block 421 to move towards the direction of the lead straightening device 2, and the clamping mechanism 40 places the capacitor 2000 with the lead 2001 upwards on one side of the chute 420a facing the jig tray 5 on the pushing block 421; when the rack 412 moves toward the jig tray 5, the turnover mechanism 41 turns the holding mechanism 40 toward the lead straightening device 2, the rack 412 drives the link 422 and the push block 421 to move toward the jig tray 5, and the push block 421 pushes the capacitor 2000 with the lead 2001 upward from the chute 420a onto the jig tray 5.
As shown in fig. 23, both ends of the gap 420b in the direction opposite to the jig tray 5 and the wire straightening device 2 are closed, whereby the closed both ends restrict the extreme positions of the movement of the link 422.
As shown in fig. 23, the end of the push block 421 facing the jig tray 5 is formed with a concave portion 421a projected in a V shape in the up-down direction D1.

The double screw valve 612 is used to supply the a and B gums from the a and B gums barrels 610 and 611, respectively, to the mixing tube 613. Mixing tube 613 is used to receive and mix the A and B gums supplied by twin screw valve 612.

Specifically, as shown in fig. 25, the lead guide mechanism 64 includes a coupling portion 640 and a guide portion 641. The connecting portion 640 connects the guide portion 641 to the elevating mechanism 63.

The guide groove 641a is a gradually-increasing bell mouth-shaped opening on the side facing the inverting feed device 4 (i.e., upstream-facing). In the injection operation of the injection molding device 6, the two leads 2001 of one capacitor 2000 enter the guide groove 641a through the opening of the gradually enlarged bell mouth shape, and the needle 621 of the dispensing valve 62 is located outside the gradually enlarged bell mouth shape in the direction perpendicular to the direction in which the jig tray 5 and the inverting feeding device 4 oppose each other (i.e., the direction in which the jig tray 5 and the upstream oppose each other), and after the injection molding is completed, the capacitor 2000, which has completed the injection molding, is pushed into the jig tray 5 through the guide groove 641a by the pushing of the next capacitor 2000 to be injected, which is fed upstream (i.e., fed by the upstream inverting feeding device 4).
Referring to fig. 24 and 25, the capacitor glue injection apparatus 1000 further includes (i.e., the glue injection module further includes) a fall prevention device 7, where the fall prevention device 7 is used to block the case 2002 of the capacitor 2000 from the side of the capacitor 2000 facing away from the roll-over feeding device 4 (i.e., facing away from the upstream) when the glue is injected into one of the capacitors 2000 by the glue injection device 6, so as to prevent the capacitor 2000 from falling over during the glue injection. Compared with the mode that the capacitor in the background art is inserted into the grid of the jig tray, by adopting the fall prevention device 7, not only the manual operation can be canceled, but also the capacitor 2000 can be conveniently positioned.
Specifically, as shown in fig. 24, the tilting prevention device 7 includes a reciprocating rectilinear motion mechanism 70, a connection plate 71, and a shutter 72, the shutter 72 being connected to the connection plate 71, the connection plate 71 being connected to the reciprocating rectilinear motion mechanism 70: the reciprocating linear motion mechanism 70 is configured to reciprocate the connection plate 71 and the shutter 72 in a direction in which the jig tray 5 and the inverting feed device 4 are opposite to each other (i.e., in a direction in which the jig tray 5 and the upstream are opposite to each other), so that the shutter 72 blocks the case 2002 of the capacitor 2000 from a side of the capacitor 2000 facing away from the inverting feed device 4 (i.e., facing away from the upstream), to prevent the capacitor 2000 from being tipped over at the time of injection.
Further, as shown in fig. 24, the reciprocating rectilinear motion mechanism 70 includes a motor 701, a screw nut transmission unit 702, and a slider 703.

The screw nut transmission unit 702 can improve the displacement accuracy of the connection plate 71 and thus the shutter 72. In one example, the baffle 72 and the connection plate 71 are a single piece plate, thereby increasing the overall rigidity of the baffle 72 and the connection plate 71, enhancing the ability to prevent the capacitor 2000 from tipping over during glue injection.
