Capacitor injection equipment

Abstract

A capacitor glue injection device is provided, comprising a loading device, a lead straightening device, a flip feeder, a jig tray, and a glue injection device. The loading device is used to hold multiple capacitors with leads and feed them to the lead straightening device in a single row with the leads facing downward. The lead straightening device is used to straighten the downward-facing leads of each capacitor. The flip feeder is used to flip the straightened capacitors so that the leads face upward and transport them to the jig tray. The glue injection device is used to inject glue and seal the top of the capacitor housing transported to the jig tray, where the leads extend out. This achieves fully automated operations for capacitor loading, lead straightening, and glue injection in the jig tray.

Description

Technical Field

[0001] The present disclosure relates to the field of capacitors, and more particularly to a capacitor glue injection device. Background Art

[0002] Currently, capacitors (such as but not limited to supercapacitors) have a short service life due to electrolyte leakage. Therefore, an additional glue injection process has been added to the existing process, using AB epoxy resin glue to prevent electrolyte leakage and ensure the long service life of the capacitor. Currently, capacitor glue injection can be done by fully manual or semi-automatic methods.

[0003] The operating process of the fully manual glue injection operation is as follows: manually straighten the pins → manually place them in the jig tray → manually draw out glue A with a syringe → manually draw out glue B with a syringe → manually inject glue AB into the capacitor in a 2:1 ratio → put it into the oven for curing.

[0004] The operating process of semi-automatic glue injection is as follows: manually straighten the pins (also called leads) → manually place them in the fixture tray → gantry three-axis glue injection machine → put them into the oven for curing.

[0005] In other words, the current capacitor glue injection process has not yet achieved fully automated operations from capacitor loading, lead straightening, and glue injection in the jig tray. This results in high labor usage and low work efficiency.

[0006] Furthermore, for the capacitor feeding part, the Chinese utility model patent application CN209493031U authorized for publication on October 15, 2019 discloses a lead monolithic capacitor discharge device. The working principle is: when the monolithic capacitor arrangement device arranges the capacitor, the capacitor is poured into the spiral screen hopper, and the vibrator drives the spiral screen hopper to vibrate. The capacitor enters the material discharge trough from the discharge port on the side of the spiral screen hopper as the spiral track inside the spiral screen hopper rotates. The capacitor pick-up and placement mechanism takes the capacitors in turn and places them into the capacitor placement slot inside the loading track bracket, thereby completing the arrangement of the capacitor. In this patent document, the capacitor does not fall directly from the material discharge trough into the capacitor placement slot inside the loading track bracket, but needs to be operated with the help of a capacitor pick-up and placement mechanism, which results in the inability of the patent document to further arrange the movement and loading from the capacitor placement slot. In addition, since the loading track bracket is fixed, it is impossible to achieve long-distance loading to meet the needs of continuous operation of subsequent processes (such as lead straightening and glue injection).

[0007] Furthermore, with regard to the pin straightening part, the Chinese utility model application authorization announcement No. CN202839319U authorized and announced on March 27, 2013 discloses an aluminum electrolytic capacitor stripping machine, in which a mountain-shaped fork lead straightening device is used to straighten the leads and then separate them. However, although this mountain-shaped fork lead straightening device can separate the two leads and straighten them to a certain extent, its straightening effect still needs to be improved.

[0008] Furthermore, for the glue injection process, the aforementioned semi-automatic gantry-type three-axis glue injection machine still pre-positions the capacitors in the jig tray with the pins facing upward. This requires positioning the capacitors during the glue injection process, either manually or by inserting them into the grid of the jig tray. This makes positioning the capacitors during glue injection inconvenient. Furthermore, although the gantry-type three-axis glue injection machine can avoid pins during the glue injection process, there is still a risk of pin collision if the operation is not appropriate. Summary of the Invention

[0009] In view of the problems existing in the background technology, the purpose of the present disclosure is to provide a capacitor glue injection device, which can realize the fully automatic operations of capacitor loading, lead straightening and glue injection in the fixture tray.

[0010] Therefore, a capacitor glue injection device is provided, which includes a loading device, a lead straightening device, a flip feeding device, a jig tray and a glue injection device; the loading device is used to hold a plurality of capacitors with leads and supply the capacitors with leads to the lead straightening device in a manner of leading downward and arranged in a single row; the lead straightening device is used to straighten the downward-facing leads of each capacitor; the flip feeding device is used to flip each capacitor with straightened leads so that the leads face upward and transport it to the jig tray; the glue injection device is used to inject glue and seal the top of the capacitor shell transported to the jig tray from which the leads extend.

[0011] The beneficial effects of the present disclosure are as follows: in the capacitor glue injection equipment according to the present disclosure, capacitors are supplied to the lead straightening device with the leads facing downward and arranged in a single row through the feeding device, the downward-facing leads of each capacitor are straightened through the lead straightening device, the capacitors with straightened leads are flipped to have the leads facing upward through the flip feeding device and are used to be conveyed to the jig tray and glue-injected and sealed through the glue injection device, thereby realizing fully automatic operations of capacitor loading, lead straightening and glue injection in the jig tray.

[0161] The accompanying drawings show embodiments of the present disclosure, and it will be understood that the disclosed embodiments are merely examples of the present disclosure, which can be implemented in various forms. Therefore, the specific details disclosed herein should not be interpreted as limiting, but merely as a basis for the claims and as a representative basis for teaching one of ordinary skill in the art to implement the present disclosure in various ways.

[0162] Reference Figure 1 and Figure 29 The capacitor glue injection device 1000 according to the present disclosure includes a loading device 1, a lead straightening device 2, a flip feeder device 4, a jig tray 5, and a glue injection device 6. The lead straightening module includes the lead straightening device. The lead straightening module may also include a flip feeder device. The glue injection module includes the jig tray 5 and the glue injection device 6. In other words, the capacitor glue injection device 1000 according to the present disclosure includes a loading device 1, a lead straightening module, and a glue injection module.

[0163] The loading device 1 is used to hold a plurality of capacitors 2000 with leads 2001 and feed the capacitors 2000 with leads 2001 to the lead straightening device 2, with the leads 2001 facing downward and arranged in a single row. The lead straightening device 2 is used to straighten the downward-facing leads 2001 of each capacitor 2000. The flip feeding device 4 is used to flip the capacitors 2000 with their leads 2001 straightened so that the leads 2001 face upward and transport them to the jig tray 5. The glue injection device 6 is used to inject glue and seal the top of the housing 2002 of the capacitor 2000 transported to the jig tray 5, where the leads 2001 extend out (i.e., to inject glue and seal the top of the housing 2002 of the capacitor 2000 on the jig tray 5).

[0164] In the capacitor glue injection equipment 1000 according to the present disclosure, the capacitors 2000 are supplied to the lead straightening device 2 by the loading device 1 in a manner such that the leads 2001 face downward and are arranged in a single row, the downward leads 2001 of each capacitor 2000 are straightened by the lead straightening device 2, the capacitors 2000 with the straightened leads 2001 are flipped by the flipping feeding device 4 so that the leads 2001 face upward and are transported to the jig tray 5, and the glue is injected and sealed by the glue injection device 6, thereby realizing fully automatic operations of loading the capacitors 2000, straightening the leads and injecting glue in the jig tray.

[0165] like Figures 2 to 9 Shown and combined Figure 1In one embodiment, the feeding device 1 includes a vibrating disk feeding mechanism 10, an inverting mechanism 11, and a linear vibrating feeding mechanism 12. The vibrating disk feeding mechanism 10 is used to hold a plurality of capacitors 2000 with leads 2001 and to feed the capacitors 2000 with leads 2001 to the inverting mechanism 11 in sequence in a spiral manner from bottom to top by repeatedly magnetically attracting and disconnecting the capacitors 2000 with leads 2001 to form vibrations. The inverting mechanism 11 is used to receive the capacitors 2000 supplied by the vibrating disk feeding mechanism 10, invert the capacitors 2000 so that the leads 2001 face downward to form a single row, and the capacitors 2000 arranged in the single row with the leads 2001 facing downward are acted upon by the upstream capacitors 2000 supplied by the vibrating disk feeding mechanism 10 to move forward in a straight line. The linear vibrating feeding mechanism 12 receives the capacitors 2000 from the inverting mechanism 11 and maintains the capacitors 2000 in a single row with the leads 2001 facing downward, vibrating in a linear manner to supply the capacitors 2000 to the lead straightening device 2 (i.e., downstream). Compared with the form of the capacitor pick-up and placement mechanism in the background art, in the feeding device 1 of the present disclosure, the arrangement and movement of the capacitors 2000 can be realized through the cooperation of the vibrating disk feeding mechanism 10, the inverting mechanism 11 and the linear vibrating feeding mechanism 12, and can be used for long-distance feeding of the capacitors 2000 to meet the needs of continuous operation of subsequent processes (i.e., lead straightening and glue injection in the present disclosure).

[0166] like Figure 2 and Figure 4A 、 Figure 4B As shown, in one example, the vibration plate feeding mechanism 10 includes a chassis 100 , a cylinder 101 , a carrier plate 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 .

[0167] The chassis 100 is stationary. The cylinder 101 is fixed to the chassis 100. A carrier plate 102 is movably housed within the cylinder 101. The carrier plate 102 is used to carry a plurality of capacitors 2000 with leads 2001, each having a non-magnetic housing 2002 (e.g., aluminum housing 2002) and magnetic leads 2001 (e.g., iron leads). An upper spiral track 103 is movably housed within the cylinder 101. The upper spiral track 103 spirals upward, and the starting section of the upper spiral track 103 is fixedly connected to the upper surface of the carrier plate 102. A first electromagnet 104 is housed within the cylinder 101, located below the carrier plate 102, and fixed to the chassis 100. The first armature 105 is housed in the cylinder 101, located below the carrier plate 102 and fixedly connected to the carrier plate 102. By turning the first electromagnet 104 on and off (the power supply is not shown), the first armature 105 and the first electromagnet 104 form a fixed frequency of magnetic attraction and disconnection, so that the upper spiral track 103 and the carrier plate 102 form vibrations in the up and down direction D1. The four first leaf springs 106 are arranged parallel to each other at 90-degree intervals, two by two. The four first leaf springs 106 are inclined relative to the axis of the carrier disk 102 and can produce repeated elastic deformation and elastic recovery when the first armature 105 and the first electromagnet 104 form a fixed-frequency magnetic attraction and disconnection, so that the upper spiral track 103 and the carrier disk 102 form a torsional vibration around the axis of the carrier disk 102. The torsional vibration, together with the vibration in the up and down directions D1, drives the capacitor 2000 with the lead 2001 on the carrier disk 102 from the carrier disk 102 along the upper spiral track 103 and supplies the capacitor 2000 to the outer spiral track 107. The outer spiral track 107 is provided at the top of the cylinder 101 and is fixed together with the cylinder 101. The outer spiral track 107 spirals outwardly around the cylinder 101. The outer spiral track 107 is used to receive the capacitors 2000 from the upper spiral track 103 and make the received capacitors 2000 use the inertial force from the upper spiral track 103 to move against each other in sequence and supply the capacitors 2000 to the inversion mechanism 11 in sequence. In the figure, the cylinder 101 limits the upper spiral track 103 in radial and circumferential directions. In addition, the structure consisting of the chassis 100, the cylinder 101, the carrier plate 102, the upper spiral track 103, the first electromagnet 104, the first armature 105, the plurality of first leaf springs 106 and the outer spiral track 107 can be commercially available, such as the vibration plate loader manufactured and sold by Dongguan Jinbiao Electronic Technology Co., Ltd.

[0168] like Figure 2 and Figure 4A 、 Figure 4BAs shown, the top of the cylinder 101 is provided with a notch 101a; the vibrating plate feeding mechanism 10 also includes a connecting piece 108, which is connected to the bottom of the notch 101a and the inner wall of the cylinder 101. The connecting piece 108 is used to connect with the top of the upper spiral track 103 to receive and support the capacitors 2000 conveyed by the upper spiral track 103 and convey the received capacitors 2000 to the outer spiral track 107. The provision of the connecting piece 108 allows the capacitors 2000 to be smoothly shifted from the upper spiral track 103 to the outer spiral track 107 by inertia. The width of the connecting piece 108 can be set wider to provide sufficient support for the capacitors 2000.

[0169] like Figure 2 and Figure 4A 、 Figure 4B As shown, the outer spiral track 107 is provided with a partition wall 109, which extends along the outer spiral track 107 and divides the outer spiral track 107 into a first receiving portion 109a and a second receiving portion 109b. The first receiving portion 109a is used to receive capacitors 2000 output from the upper spiral track 103 and used for loading; the second receiving portion 109b is used to receive capacitors 2000 output from the upper spiral track 103 but not used for loading. The provision of the first receiving portion 109a and the second receiving portion 109b not only accommodates the situation where the capacitors 2000 output from the upper spiral track 103 are not one after another due to vibration, but also accommodates the situation where a capacitor 2000 that has just entered the first receiving portion 109a and a capacitor 2000 that is already in the first receiving portion 109a cannot be arranged in sequence, and therefore jumps out of the first receiving portion 109a and enters the second receiving portion 109b due to the inertia of vibration movement. In the figure, the first receiving portion 109a is radially inward and the second receiving portion 109b is radially outward, and the connecting piece 108 is spaced apart from the second receiving portion 109b. Of course, in alternative embodiments, the first receiving portion is radially outward and the second receiving portion is radially inward, that is, the first receiving portion 109a in the figure becomes the second receiving portion, and the second receiving portion 109b becomes the first receiving portion. In this case, the connecting piece 108 spans the first receiving portion 109a and connects to the second receiving portion 109b. Capacitors 2000 contained in the second receiving portion 109b but not available for loading can be automatically dropped back onto the carrier tray 102 through the provision of a return channel (not shown).

[0170] like Figure 4A and Figure 4B As shown, in one example, the side of the partition wall 109 facing the shell 2002 is a slope inclined from the outside to the inside.

[0171] like Figure 4AAs shown, the inversion mechanism 11 includes a support bar 110; the support bar 110 is connected to the end of the outer spiral track 107 and the partition wall 109, and the end of the partition wall 109 is provided with a gap 109c that passes through along the up-down direction D1; the support bar 110 has an upper plane 110a, a stop surface 110b and a through hole 110c, the stop surface 110b is orthogonal to the slope of the partition wall 109, the top edge of the stop surface 110b and the outer edge of the slope of the end of the partition wall 109 are coplanar with the upper plane 110a; the through hole 110c passes through the support bar 110 along the up-down direction D1 and extends straight through the support bar 110 in a direction perpendicular to the up-down direction D1, and the through hole 110c passes through the stop surface 110b, and the through hole 110c is connected to the gap 109c of the partition wall 109 at the stop surface 110b. The lead 2001 of the capacitor 2000 enters the connected gap 109c and the through hole 110c, and the shell 2002 of the capacitor 2000 moves to the upper plane 110a of the support bar 110 through the slope surface and the stop surface 110b of the partition wall 109 to be inverted.

[0172] like Figure 4B As shown, in an alternative example, the inversion mechanism 11 includes a support bar 110 and two posture adjustment plates 111 (both of which are shown in a perspective state in FIG4 ); the support bar 110 is connected to the end of the outer spiral track 107 and the partition wall 109, and the end of the partition wall 109 is provided with a gap 109c that passes through in the up-down direction D1; the support bar 110 has an upper plane 110a, a stop surface 110b and a through hole 110c; the through hole 110c passes through the support bar 110 in the up-down direction D1 and is perpendicular to the up-down direction D1. A straight line extends through the support bar 110 in a straight direction, and the through hole 110c passes through the stop surface 110b, and the through hole 110c is connected to the gap 109c of the partition wall 109 at the stop surface 110b; the two posture adjustment plates 111 are radially located on both sides of the partition wall 109 and the posture adjustment plate 111 on the radial inner side gradually stands up to allow the capacitor 2000 with the lead 2001 moving along the partition wall 109 to gradually stand up and enter the gap 109c of the partition wall 109, and then enter the through hole 110c of the support bar 110.

[0173] exist Figure 4A and Figure 4B In the example of Figure 4A and Figure 4BMagnetic unit 112 is located below support bar 110 and outer spiral track 107 and is aligned with through-hole 110c of support bar 110 and partition wall 109 in vertical direction D1. This magnetic attraction forces all capacitors 2000 traveling within first receiving portion 109a to be positioned with the ends of their leads 2001 radially pointing toward partition wall 109, allowing leads 2001 of the traveling capacitors 2000 to enter the interconnected gaps 109c and through-hole 110c, and allowing housings 2002 of the traveling capacitors 2000 to move via the sloped surface and stop surface 110b of partition wall 109 onto the upper flat surface 110a of support bar 110, thereby becoming inverted. Magnetic unit 112 can be in the form of a magnet.

[0174] like Figure 5 As shown, the linear vibration feeding mechanism 12 includes a supporting unit 120 and a linear vibration unit 121 . The support unit 120 has a support portion 120a, and the support portion 120a has a gap 120a1. The gap 120a1 penetrates the support portion 120a along the up-down direction D1 and penetrates the support portion 120a along the direction toward the loading device 1 to the lead straightening device 2 (i.e., downstream). The upper part of the support portion 120a is used to accommodate the shell 2002 of the capacitor 2000, the gap 120a1 of the support portion 120a and the lower part of the support portion 120a are used to accommodate the leads 2001 of the capacitor 2000, and the upper surface of the support portion 120a is used to support the shell 2002 of the capacitor 2000; the linear vibration unit 121 is connected to the support unit 120, and the linear vibration unit 121 is used to generate linear reciprocating vibration so that the capacitors 2000 with the leads 2001 facing downward supported by the support portion 120a of the support unit 120 are sequentially supplied linearly toward the lead straightening device 2 (i.e., toward downstream). Likewise, a magnetic attraction unit, such as a magnet, may be provided below the gap 120a1 of the support portion 120a to accommodate a situation where the capacitor 2000 is relatively tall, thereby improving stability.

[0175] like Figure 9As shown, the linear vibration unit 121 includes a base 121a, a top plate 121b, two second leaf springs 121c, a second electromagnet 121d and a second armature 121e; the base 121a is fixed; the top plate 121b is spaced apart from the base 121a along the up-down direction D1, and the top plate 121b is connected to the support portion 120a of the support unit 120; the two second leaf springs 121c are parallel to each other, and the two second leaf springs 121c are arranged on the top plate 121b and the base 121 a along the linear motion direction of the linear vibration unit 121, the upper end and lower end of each second leaf spring 121c are fixedly connected to the top plate 121b and the base 121a respectively, and the two second leaf springs 121c, the base 121a and the top plate 121b form a receiving space S, and each second leaf spring 121c is inclined relative to the up-down direction D1; the second electromagnet 121d is located in the receiving space S and fixed to the base 121a; the second armature 121e is received in the receiving space S and fixed It is fixedly connected to the top plate 121b, and through the on and off of the second electromagnet 121d (the power supply is not shown), the second armature 121e and the second electromagnet 121d form a fixed frequency of magnetic attraction and disconnection in the straight line direction perpendicular to the up and down direction D1 relative to the two second leaf springs 121c, so that the two second leaf springs 121c elastically deform and elastically recover in the straight line direction perpendicular to the up and down direction D1 when the first armature 105 and the first electromagnet 104 form a fixed frequency of magnetic attraction and disconnection, and then generate vibration in the straight line direction perpendicular to the up and down direction D1, so that the support part 120a of the support unit 120 fixedly connected to the two second leaf springs 121c via the top plate 121b generates vibration in the straight line direction, and then the capacitor 2000 supported on the support part 120a of the support unit 120 is fed to the lead straightening device 2 along the gap 120a1 with the lead 2001 facing downward. Likewise, the linear vibration unit 121 may also be commercially available, such as a linear vibrator manufactured and sold by Dongguan Jinbiao Electronic Technology Co., Ltd.

[0176] like Figures 5 to 8 As shown, the linear vibration feeding mechanism 12 further includes two side limiters 122, which are parallel to each other and spaced apart. The two side limiters 122 are respectively located on both sides of the gap 120a1 of the support portion 120a. The two side limiters 122 are used to limit the capacitor 2000 fed by the support portion 120a from turning over from both sides of the support portion 120a perpendicular to the direction in which the gap 120a1 extends. Further, as Figure 5 and Figure 6 As shown, the ends of the two side limiting members 122 adjacent to the inverting mechanism 11 are chamfered to guide the capacitor 2000 from the inverting mechanism 11 to enter the supporting portion 120a.

[0177] like Figures 5 to 7As shown, the linear vibration feeding mechanism 12 also includes an upper limit member 123, which is located above the support portion 120a and spaced apart from the support portion 120a. The upper limit member 123 is used to limit the linear vibration fed capacitor 2000 on the support portion 120a from above to avoid the linear vibration fed capacitor 2000 on the support portion 120a from piling up during the linear motion process.

[0178] like Figures 5 to 8 As shown, the linear vibration feeding mechanism 12 further includes a lifting unit 124, which is connected to the upper limit member 123. The lifting unit 124 is used to lift the upper limit member 123 relative to the support portion 120a and adjust the distance between the upper limit member 123 and the support portion 120a in the vertical direction D1 to meet the needs of the housing 2002 of the capacitor 2000 of different heights. Figures 5 to 8 As shown, the lifting unit 124 is connected to the limiting member 123 by bolts. In alternative embodiments, the lifting unit 124 can be in the form of a cylinder, a hydraulic cylinder, a linear motor, etc.

[0179] like Figure 5 and Figure 6 As shown, the linear vibration feeding mechanism 12 further includes a guide unit 125, which is located at the rear end of the support unit 120 adjacent to the lead straightening device 2 (i.e., downstream). The guide unit 125 has two curved arms 125a, and the distance between the two curved arms 125a decreases from the end facing the inverting mechanism 11 to the end facing the lead straightening device 2 (i.e., downstream). This guides and clamps the capacitor 2000 being fed by the support unit 120 toward the lead straightening device 2 (i.e., downstream). In this way, the capacitor 2000 is fed to the lead straightening device 2 in a centered position.

[0180] Furthermore, the guide unit 125 also includes two pivots 125b and a bracket 125c. The bottom ends of the two pivots 125b are pivotally fixed to the bracket 125c, while the upper portions of the two pivots 125b pass through and are fixed to the two curved arms 125a, respectively, so that the two curved arms 125a can pivot and thus open or close. Thus, the two pivotable curved arms 125a can clamp and release the housing 2002 of the corresponding capacitor 2000, so that the first clamping mechanism 20 of the subsequent lead straightening device 2 can accurately pick up. Each pivot 125b is equipped with a torsion spring or tension spring (not shown) to enable each pivot 125b to elastically open when the two curved arms 125a contact and release the housing 2002 of the capacitor 2000, and close due to the recovery of the torsion spring after the two curved arms 125a contact and release the housing 2002 of the capacitor 2000.

[0181] like Figure 5As shown, each curved arm 125a includes a main body 125a1 and two fingers 125a2. The two fingers 125a2 extend from the main body 125a1 toward the lead straightening device 2 (i.e., toward the downstream), and the two fingers 125a2 are spaced apart in the vertical direction D1. The spacing between the main bodies 125a1 of the two curved arms 125a is greater than the spacing between the opposing fingers 125a2 of the two curved arms 125a. The spacing between the opposing fingers 125a2 of the two curved arms 125a decreases from the main body 125a1 toward the lead straightening device 2 (i.e., toward the downstream). This improves the stability of the two curved arms 125a in clamping the capacitor 2000 housing 2002.

[0182] like Figure 5 As shown, the end of each finger portion 125a2 is an arc surface, and the distance between the arc surfaces of the opposite finger portions 125a2 of the two curved arms 125a gradually decreases from the main body 125a1 toward the lead straightening device 2 (i.e., toward the downstream); the guide unit 125 also includes two flat plates 125d, which are respectively erected on the two side limit members 122, and the distance between the two flat plates 125d is smaller than the distance between the two side limit members 122; each flat plate 125d has a notch 125d1, and the notch 125d1 is located on each flat plate 125 d is the end of a single adjacent lead straightening device 2 (i.e., adjacent downstream), the notch 125d1 allows the portion near the end of the two fingers 125a2 of a corresponding curved arm 125a to pass through, and the portion of each flat plate 125d located above the notch 125d1 protrudes toward the lead straightening device 2 (i.e., downstream) beyond the end of each lateral limit member 122, and the vertical wall of each flat plate 125d that forms the notch 101a facing the lead straightening device 2 (i.e., facing downstream) is used to limit the two fingers 125a2 of the corresponding curved arm 125a.

[0183] Reference Figure 10 、 Figure 11 、 Figure 13 and Figure 15The lead straightening device 2 includes a first clamping mechanism 20, a second clamping mechanism 21, a third clamping mechanism 22, a lead separation mechanism 23, and a first lead straightening mechanism 24. The first clamping mechanism 20 receives a capacitor 2000 with its leads 2001 facing downward from the loading device 1 (i.e., upstream) and transfers the received capacitor 2000 with its leads 2001 facing downward to the lead separation mechanism 23. The lead separation mechanism 23 is used to receive and support the capacitor 2000 with its leads 2001 facing downward transferred by the first clamping mechanism 20 and separate the two leads 2001 of the capacitor 2000 from the middle. The second clamping mechanism 21 is configured to clamp the housing 2002 of the capacitor 2000 supported by the lead-separating mechanism 23 when the lead-separating mechanism 23 supports the capacitor 2000 with its leads 2001 facing downward, and after the lead-separating mechanism 23 separates the two leads 2001 of the capacitor 2000 from the center, transfer the capacitor 2000 with its two leads 2001 separated from the center to the first lead-straightening mechanism 24. The first lead-straightening mechanism 24 is configured to receive and support the capacitor 2000 with its two leads 2001 separated from the center transferred by the second clamping mechanism 21, and further straighten the two leads 2001 separated from the center in the direction in which the two leads 2001 separate from the center. The third clamping mechanism 22 is used to clamp the housing 2002 of the capacitor 2000 supported by the first lead-straightening mechanism 24 while the first lead-straightening mechanism 24 supports the two leads 2001 separated from the middle of the capacitor 2000, and after the first lead-straightening mechanism 24 straightens the two leads 2001 separated from the middle, it conveys the capacitor 2000 with the two straightened leads 2001 downstream (i.e., toward the downstream flip feeding device 4). Compared to the prior art that only uses a mountain-shaped fork lead straightening device, the lead straightening module of the present disclosure improves the lead straightening effect of the capacitor 2000 through the lead separation mechanism 23 of the lead straightening device 2 and the first lead straightening mechanism 24.

[0184] like Figure 16 and Figure 17 As shown, in one example, the lead separation mechanism 23 includes a support table 231 and a lead separation unit 232 .

[0185] The support platform 231 includes a fixed block 231a, a movable block 231b, a vertical actuator 231c, and a horizontal actuator 231d. The fixed block 231a has a top surface 231a1, which serves as a support surface for the end of the housing 2002 of the corresponding capacitor 2000. The movable block 231b forms a sliding pair with the fixed block 231a, slidingly engaging in the vertical direction D1. The movable block 231b is provided with a protrusion 231b1 that protrudes toward the lead separation unit 232. The vertical actuator 231c is connected to the movable block 231b to drive the movable block 231b to reciprocate relative to the fixed block 231a in the vertical direction D1. The horizontal actuator 231d is connected to the fixed block 231a to drive the fixed block 231a, movable block 231b, and vertical actuator 231c toward and away from the lead separation unit 232. Both the vertical actuator 231c and the horizontal actuator 231d can be pneumatic cylinders.

[0186] The lead separation unit 232 includes a driving portion 232a, a pusher portion 232b, an insertion portion 232c, and two movable clamping arms 232d. The pusher portion 232b is connected to the driving portion 232a. The top of the pusher portion 232b is a pointed column. The insertion portion 232c has a pointed column with a horizontally extending groove 232c1. The end edge of the pointed column extends downward and faces the movable block 231b. The insertion portion 232c is located between the pusher portion 232b and the movable block 231b. Each movable clamping arm 232d includes an arm portion 232d1, a driven wheel 232d2, and a block 232d3. The arm portion 232d1 has a first end E1 and a second end E2. The first end E1 of the arm portion 232d1 is adjacent to the driving portion 232a, while the second end E2 of the arm portion 232d1 is adjacent to the movable block 231b. The driven wheel 232d2 is provided at the first end E1 of the arm 232d1, the block 232d3 is provided at the second end E2 of the arm 232d1, the arm 232d1 is pivotable and elastically recoverable and is provided on one side of the insertion portion 232c, and the interval between the driven wheels 232d2 of the two movable clamping arms 232d is greater than the minimum width of the head of the pushing portion 232b and smaller than the maximum width of the head of the pushing portion 232b when there is no force. The block 232d3 of the movable clamping arm 232d is provided with a horizontally extending recess R. When the blocks 232d3 of the two movable clamping arms 232d are collapsed onto the sides of the head of the insert portion 232c when not in force, and their surfaces facing the movable block 231b are coplanar. The recess R of the blocks 232d3 of the two movable clamping arms 232d and the groove 232c1 of the head of the insert portion 232c are aligned vertically to accommodate the protrusion 231b1 of the movable block 231b. The driving portion 232a may be a cylinder.

[0187] During operation, the vertical driver 231c drives the movable block 231b to move up and down relative to the fixed block 231a so that the protrusion 231b1 of the movable block 231b is aligned with the recess R of the block 232d3 of the two movable clamping arms 232d and the groove 232c1 of the head of the insertion portion 232c, and then the top surface 231a1 of the fixed block 231a of the support table 231 supports the end of the shell 2002 of the corresponding capacitor 2000, and the two leads 2001 of the capacitor 2000 extend downward from the surface of the side of the support table 231 facing the lead separation unit 232, and the horizontal driver 232d drives the fixed block 231a, the movable block 231b and the vertical driver 231c to move toward the lead separation unit 232 so that the protrusion 231b1 of the movable block 231b is inserted into the block 232d of the two movable clamping arms 232d aligned up and down. The recess R of the body 232d3 and the groove 232c1 of the head of the insertion part 232c, the driving part 232a of the lead separation unit 232 drives the pushing part 232b to move forward, and the head of the pushing part 232b is inserted between the driven wheels 232d2 of the two movable clamping arms 232d so that the arm parts 232d1 of the two movable clamping arms 232d are pivoted relative to the insertion part 232c and opened, and the head of the pushing part 232b abuts against the insertion part 232c and pushes the insertion part 232c and the two movable clamping arms 232d to move toward the fixed block 231a together. The opened two movable clamping arms 232d make the two blocks 232d3 avoid the two leads 2001 and as the head of the pointed column of the insertion part 232c is gradually inserted between the two leads 2001, the two leads 2001 are separated by the pointed column.

[0188] like Figure 18 and Figure 19 As shown, in one example, the first wire straightening mechanism 24 includes a first component 241 and a second component 242 .

[0189] First component 241 includes a top surface 241a, side surfaces 241b, a protrusion 241c, an upper positioning groove 241d, and two lower positioning grooves 241e. Top surface 241a is used to support the end of housing 2002 of capacitor 2000. Side surfaces 241b face second component 242, and protrusions 241c protrude from side surfaces 241b toward second component 242. The protrusion 241c comprises two triangular cylindrical grooves 241c1 recessed away from the second component 242, and a pointed protrusion 241c2 located between the two triangular cylindrical grooves 241c1. The bottom edges of the two triangular cylindrical grooves 241c1 are coplanar with the side surface 241b of the first component 241. The axes of the two lower positioning grooves 241e are coplanar with the bottom edges of the two triangular cylindrical grooves 241c1. The pointed protrusion 241c2 is inserted between the two leads 2001 of the corresponding capacitor 2000 and guides the two leads 2001 to the bottom of the two triangular cylindrical grooves 241c1 via the side slopes of the pointed protrusion 241c2. The second component 242 comprises a mating body 242a, two upper electrical contacts 242b, two lower electrical contacts 242c, and a driving member 242d. The mating body 242a is provided with a recess 242a1 and a side surface 242a2. The side surface 242a2 is parallel to the side surface 241b of the first component 241 and both are flat. The recess 242a1 of the mating body 242a is recessed from the side surface 242a2 and is used to accommodate the protrusion 241c of the first component 241. The two upper electrical contacts 242b are located above the recess 242a1 and aligned with the upper positioning groove 241d. The axes of the two upper electrical contacts 242b are respectively coplanar with the bottom edges of the two triangular cylindrical grooves 241c1. The two lower electrical contacts 242c are located below the recess 242a1 and are respectively aligned with the two lower positioning grooves 241e. An upper electrical contact 242b and a lower electrical contact 242c are aligned vertically and connected to an external circuit (not shown). Together, they are used to determine whether one lead 2001 is long or short, and the front-to-back order of the lead 2001, by determining whether the lead 2001 is electrically conductive to the other lead 2001. Another upper electrical contact 242b and another lower electrical contact 242c are aligned vertically and connected to an external circuit (not shown). Together, they are used to determine whether the other lead 2001 is long or short, and the front-to-back order of the other lead 2001, by determining whether the other lead 2001 is electrically conductive to the other lead 2001. A driving member 242d is connected to the mating body 242a to drive the mating body 242a, along with the two upper electrical contacts 242b and the two lower electrical contacts 242c, toward the first component 241.

[0190] During operation, the top surface 241a supports the end of the shell 2002 of the corresponding capacitor 2000, and the two leads 2001 of the capacitor 2000 extend downward along the side surface 241b of the first component 241 and pass through the two triangular cylindrical grooves 241c1 of the protrusion 241c respectively. The driving member 242d of the second component 242 drives the matching body 242a together with the two upper electrical contacts 242b and the two lower electrical contacts 242c to move toward the first component 241. The protrusion 241c of the first component 241 approaches the recess 242a1 of the matching body 242a, the two upper electrical contacts 242b of the matching body 242a approach the upper positioning groove 241d, and the two lower electrical contacts 242c of the matching body 242a approach the two lower positioning grooves 241e. The upper and lower aligned upper electrical contacts 242a are aligned with each other. At least the upper electrical contact 242b of one of the upper and lower electrical contacts 242c pushes the corresponding lead 2001 toward the bottom of the corresponding triangular cylindrical slot 241c1, while at least the upper electrical contact 242b of the other upper and lower electrical contacts 242b, 242c, which are aligned vertically, pushes the corresponding other lead 2001 toward the bottom of the corresponding other triangular cylindrical slot 241c1, thereby straightening the two leads 2001. At the same time, the upper and lower electrical contacts 242b, 242c, and the other upper and lower electrical contacts 242b, 242c, which are aligned vertically, determine whether the other lead 2001 is long or short and the order of the two leads 2001 by whether they are electrically conductive. In this way, the straightening and length determination of the two leads 2001 are simultaneously achieved. The spacing between the corresponding aligned upper and lower electrical contacts 242b, 242c is determined by the lengths of the two leads 2001 of the applicable capacitor 2000. When the two leads 2001 are of different lengths (typically, the positive lead 2001 is longer, while the negative lead 2001 is shorter), the shorter lead 2001 will not be electrically conductive with the corresponding upper and lower electrical contacts 242b, 242c, while the longer lead 2001 will be electrically conductive with the corresponding upper and lower electrical contacts 242b, 242c. Note that the two upper and lower electrical contacts 242b, 242c are insulated and disposed on the mating body 242a, and the first component 241 can be formed entirely of insulating material.

[0191] Reference Figure 11 、 Figure 13 、 Figure 15 、 Figure 20 and Figure 21The lead straightening device 2 further includes a lead rotating mechanism 26 and a fourth clamping mechanism 27. After the first lead straightening mechanism 24 straightens the two leads 2001 separated from the middle, the capacitor 2000 with the two straightened leads 2001 is conveyed downstream (i.e., to the downstream flip feeding device 4) in an indirect manner. The third clamping mechanism 22 conveys the capacitor 2000 with the two straightened leads 2001 to the lead rotating mechanism 26 after the first lead straightening mechanism 24 straightens the two leads 2001 separated from the middle. The lead rotation mechanism 26 communicates with the first lead straightening mechanism 24. If the lead rotation mechanism 26 determines that the front and back order of the two leads 2001 meets the requirements, the lead rotation mechanism 26 does not rotate and the lead rotation mechanism 26 only clamps the two straightened leads 2001 of the capacitor 2000 transmitted by the third clamping mechanism 22. If the lead rotation mechanism 26 determines that the front and back order of the two leads 2001 does not meet the requirements, the lead rotation mechanism 26 receives and clamps the two straightened leads 2001 of the capacitor 2000 transmitted by the third clamping mechanism 22, and the lead rotation mechanism 26 rotates the clamped capacitor 2000 180 degrees so that the front and back order of the two leads 2001 meets the requirements. The fourth clamping mechanism 27 communicates with the lead rotation mechanism 26. If the lead rotation mechanism 26 determines that the front and back order of the two leads 2001 meets the requirements, the lead rotation mechanism 26 does not rotate, the lead rotation mechanism 26 only clamps the two straight leads 2001 of the capacitor 2000 transmitted by the third clamping mechanism 22, and the lead rotation mechanism 26 releases the two straight leads 2001 of the capacitor 2000 while the fourth clamping mechanism 27 clamps the shell 2002 of the capacitor 2000 and transmits the capacitor 2000 downstream. If the lead rotation mechanism 26 determines that the front and back order of the two leads 2001 does not meet the requirements, the lead rotation mechanism 26 rotates the clamped capacitor 2000 180 degrees to make the front and back order of the two leads 2001 meet the requirements, and the lead rotation mechanism 26 releases the two straight leads 2001 of the capacitor 2000 while the fourth clamping mechanism 27 clamps the shell 2002 of the capacitor 2000 rotated 180 degrees and transmits it downstream.

[0192] Furthermore, in one example, Figure 20 and Figure 21 As shown, the lead rotation mechanism 26 includes a rotation unit 261 and a tweezers unit 262; the rotation unit 261 is connected to the tweezers unit 262, and the rotation unit 261 can drive the tweezers unit 262 to rotate at least 180 degrees; the tweezers unit 262 includes two opposing tweezers arms 262a that can open and close.

[0193] Specifically, in one example, Figure 20As shown, the rotating unit 261 includes a connecting body 261a, a first gear 261b, a first rack 261c, and a first cylinder 261d. The tweezers unit 262 is disposed on the connecting body 261a, the first gear 261b is disposed at the bottom of the connecting body 261a, the first rack 261c is engaged with the first gear 261b, and the first cylinder 261d includes a first cylinder body 261d1 and a first piston 261d2. The first piston 261d2 can linearly move in and out of the first cylinder body 261d1, and the end of the first piston 261d2 exposed from the first cylinder body 261d1 is fixedly connected to the first rack 261c.

[0194] Specifically, in one example, Figure 15 and Figure 21 As shown, the tweezers unit 262 also includes two second gears 262b, a second spring 262c, a second cylinder 262d, and a horizontal U-shaped frame 262e. The two second gears 262b are respectively integrally disposed on the two tweezers arms 262a. The two second gears 262b mesh with each other. The two tweezers arms 262a are pivotally connected to the connecting body 261a of the rotating unit 261 at the center of the two second gears 262b. The second spring 262c is connected to the bottom ends of the two tweezers arms 262a. The second cylinder 262d includes a second cylinder body 262d1 and a second piston 262d2. The second piston 262d2 can move linearly in and out of the second cylinder body 262d1. The horizontal U-shaped frame 262e is connected to the second piston 262d2 and surrounds the two tweezers arms 262a. When the second piston 262d2 moves in and out of the second cylinder body 262d1, the horizontal U-shaped frame 262e is aligned with the outer side of the bottom of one of the tweezers arms 262a to apply force and compress the second spring 262c to make the one tweezers arm 262a open relative to the other tweezers arm 262a. When no force is applied, the two tweezers arms 262a are closed by the elastic expansion recovery force of the second spring 262c.

[0195] Reference Figure 11 and Figure 15The lead straightening device 2 further includes a second lead straightening mechanism 28 and a fifth clamping mechanism 29. The second lead straightening mechanism 28 has the same structure as the first lead straightening mechanism 24. The second lead straightening mechanism 28 is used to receive and support the capacitor 2000 conveyed by the fourth clamping mechanism 27, further straighten the two leads 2001 of the capacitor 2000 in the direction in which the two leads 2001 separate, and re-check the length and front-to-back order of the two leads 2001. The fifth clamping mechanism 29 is used to clamp the housing 2002 of the capacitor 2000 supported by the second lead straightening mechanism 28 when the second lead straightening mechanism 28 supports the capacitor 2000 conveyed by the fourth clamping unit, and after the second lead straightening mechanism 28 straightens the two leads 2001 again and re-checks the length and front-to-back order of the two leads 2001, convey the capacitor 2000 with the straightened two leads 2001 downstream. The second lead wire straightening mechanism 28 plays a role in reconfirming the length and front-to-back sequence of the two lead wires 2001 relative to the first lead wire straightening mechanism 24 .

[0196] Reference Figure 11 and Figure 15 The lead straightening device 2 further includes a third lead straightening mechanism 30 and a sixth clamping mechanism 31. The third lead straightening mechanism 30 is used to receive and support the capacitor 2000 conveyed by the fifth clamping mechanism 29 and straighten the two leads 2001 of the capacitor 2000 in a direction perpendicular to the direction in which the two leads 2001 separate. In other words, the function of the third lead straightening mechanism 30 is to make the two leads 2001 coplanar. The sixth clamping mechanism 31 is used to clamp the housing 2002 of the capacitor 2000 supported by the third lead straightening mechanism 30 when the third lead straightening mechanism 30 supports the capacitor 2000 conveyed by the fifth clamping unit, and after the third lead straightening mechanism 30 straightens the two leads 2001 in a direction perpendicular to the direction in which the two leads 2001 separate, the capacitor 2000 with the two leads 2001 straightened again is conveyed downstream.

[0197] Specifically, if Figure 15As shown, the third lead straightening mechanism 30 includes a support block 300, a pressing block 301, and a driving body 302. The support block 300 has a top plane 300a and a vertical plane 300b. The top plane 300a is used to support the end of the shell 2002 of the corresponding capacitor 2000. The pressing block 301 has opposite vertical surfaces 301a. The two leads 2001 of the capacitor 2000 are located between the vertical plane 300b of the support block 300 and the vertical surface 301a of the pressing block 301. The driving body 302 is connected to the pressing block 301 to drive the pressing block 301 to move toward the support block 300 in a direction relative to the vertical plane 300b and the vertical surface 301a, so that the two leads 2001 of the capacitor 2000 are pressed between the vertical plane 300b of the support block 300 and the vertical surface 301a of the pressing block 301 and are straightened.

[0198] Reference Figure 11 The lead straightening device 2 further includes a fourth lead cutting mechanism 32 and a seventh clamping mechanism 33. The fourth lead cutting mechanism 32 is used to receive and support the capacitor 2000 conveyed by the sixth clamping mechanism 31 and cut the two leads 2001 of the capacitor 2000 to the same length; the seventh clamping mechanism 33 is used to clamp the housing 2002 of the capacitor 2000 supported by the fourth lead cutting mechanism 32 when the fourth lead cutting mechanism 32 supports the capacitor 2000 conveyed by the sixth clamping mechanism, and after the fourth lead cutting mechanism 32 cuts the two leads 2001, it transfers the capacitor 2000 with the cut leads 2001 downstream.

[0199] More specifically, refer to Figure 15 The fourth lead cutting mechanism 32 includes a support surface 321, a first cutter 321, and a second cutter 322. The support surface 321 is used to support the end of the housing 2002 of the corresponding capacitor 2000. The first cutter 322 is located below the support surface 321. The second cutter 323 is opposite to the first cutter 322 and cooperates with the first cutter 322 to shorten the two leads 2001 passing from the support surface 321 downward and between the second cutter 323 and the first cutter 322. It is noted that in actual operation, if it is not necessary to shorten the two leads 2001, the fourth lead cutting mechanism 32 and the seventh clamping mechanism 33 can be omitted, or the fourth lead cutting mechanism 32 and the seventh clamping mechanism 33 can be retained, with only the second cutter 323 and the first cutter 322 not required to cut, and the support surface 321 taking over the function of conveying the capacitor 2000 by the sixth clamping mechanism 31.

[0200] Reference Figure 11The lead-straightening device 2 further includes a fifth lead-straightening mechanism 34 and an eighth clamping mechanism 35. The fifth lead-straightening mechanism 34 has the same structure as the third lead-straightening mechanism 32. The fifth lead-straightening mechanism 34 is used to receive and support the capacitor 2000 conveyed by the seventh clamping mechanism 33 and to straighten the two leads 2001 of the capacitor 2000 again in a direction perpendicular to the direction in which the two leads 2001 separate. The eighth clamping mechanism 35 is used to clamp the housing 2002 of the capacitor 2000 supported by the fifth lead-straightening mechanism 34 when the fifth lead-straightening mechanism 34 supports the capacitor 2000 conveyed by the seventh clamping unit, and after the fifth lead-straightening mechanism 34 straightens the two leads 2001 again, convey the capacitor 2000 with the straightened two leads 2001 downstream (specifically, to the flip feeding device 4).

[0201] Reference Figure 15 The lead straightening device 2 further includes a first translation mechanism 36 and a second translation mechanism 37.

The second translation mechanism 37 is used to drive the second component 242 of the first lead straightening mechanism 24 and the second lead straightening mechanism 28, the lead rotating mechanism 26, the lead separation unit 232 of the lead separation mechanism 23, the pressing block 301 and the driving body 302 of the third lead straightening mechanism 30 and the fifth lead straightening mechanism 34, and the second cutter 323 of the fourth lead cutting mechanism 32 to translate. The first translation mechanism 36 and the second translation mechanism 37 realize the overall position adjustment of the lead separation mechanism 23, the first lead straightening mechanism 24, the lead rotation mechanism 26, the second lead straightening mechanism 28, the third lead straightening mechanism 30, the fourth lead cutting mechanism 32, and the fifth lead straightening mechanism 34.

[0202] Reference Figure 11 The lead straightening device 2 further includes a linear reciprocating motion mechanism 38. The linear reciprocating motion mechanism 38 is fixedly connected to the first clamping mechanism 20, the second clamping mechanism 21, the third clamping mechanism 22, the fourth clamping mechanism 27, the fifth clamping mechanism 29, the sixth clamping mechanism 31, the seventh clamping mechanism 33, and the eighth clamping mechanism 35. The first clamping mechanism 20, the second clamping mechanism 21, the third clamping mechanism 22, the fourth clamping mechanism 27, the fifth clamping mechanism 29, the sixth clamping mechanism 31, the seventh clamping mechanism 33, and the eighth clamping mechanism 35 are connected to the linear reciprocating motion mechanism 38 at equal intervals along the direction from the loading device 1 to the flip feeding device 4 (i.e., from upstream to downstream).

[0203] When the linear reciprocating motion mechanism 38 moves downstream once at equal intervals, the first clamping mechanism 20 transfers the capacitor 2000 to the lead separating mechanism 23, the second clamping mechanism 21 transfers the capacitor 2000 to the first lead straightening mechanism 24, the third clamping mechanism 22 transfers the capacitor 2000 to the lead rotating mechanism 26, the fourth clamping mechanism 27 transfers the capacitor 2000 to the second lead straightening mechanism 28, the fifth clamping mechanism 29 transfers the capacitor 2000 to the third lead straightening mechanism 30, the sixth clamping mechanism 31 transfers the capacitor 2000 to the fourth lead cutting mechanism 32, the seventh clamping mechanism 33 transfers the capacitor 2000 to the fifth lead straightening mechanism 34, and the eighth clamping mechanism 35 transfers the capacitor 2000 to the flip feeding device 4 (i.e., downstream).

[0204] When the linear reciprocating motion mechanism 38 moves upstream once at equal intervals, the first clamping mechanism 20 receives and clamps the shell 2002 of the capacitor 2000 transmitted from the feeding device 1 (i.e., from upstream), the second clamping mechanism 21 clamps the shell 2002 of the capacitor 2000 supported by the lead separation mechanism 23, the third clamping mechanism 22 clamps the shell 2002 of the capacitor 2000 supported by the first lead straightening mechanism 24, the fourth clamping mechanism 27 clamps the shell 2002 of the capacitor 2000 supported by the lead rotation mechanism 26, and the fifth clamping mechanism 29 clamps The second lead straightening mechanism 28 clamps the shell 2002 of the supported capacitor 2000, the sixth clamping mechanism 31 clamps the shell 2002 of the capacitor 2000 supported by the third lead straightening mechanism 30, the seventh clamping mechanism 33 clamps the shell 2002 of the capacitor 2000 supported by the fourth lead cutting mechanism 32, and the eighth clamping mechanism 35 clamps the shell 2002 of the capacitor 2000 supported by the fifth lead straightening mechanism 34, so as to realize the clamping state of the shell 2002 of the corresponding capacitor 2000 before the linear reciprocating motion mechanism 38 moves downstream at equal intervals.

[0205] Reference Figure 10 The linear reciprocating motion mechanism 38 includes a slide 380, a linear guide rail 381, and a mechanism driver 38D. The slide 380 is fixedly connected to the first clamping mechanism 20, the second clamping mechanism 21, the third clamping mechanism 22, the fourth clamping mechanism 27, the fifth clamping mechanism 29, the sixth clamping mechanism 31, the seventh clamping mechanism 33, and the eighth clamping mechanism 35. The slide 380 is in sliding engagement with the linear guide rail 381. The mechanism driver 38D is connected to the slide 380 to drive the slide 380 to reciprocate along the linear guide rail 381. The mechanism driver 38D can be in the form of a pneumatic cylinder, a hydraulic cylinder, a linear motor, or the like.

[0206] Reference Figure 13 and Figure 14The first clamping mechanism 20, the second clamping mechanism 21, the third clamping mechanism 22, the fourth clamping mechanism 27, the fifth clamping mechanism 29, the sixth clamping mechanism 31, the seventh clamping mechanism 33, and the eighth clamping mechanism 35 each include a first horizontal rod gh1, a first vertical rod gv1, a second horizontal rod gh2, a second vertical rod gv2, and a gear body T. The first horizontal rod gh1 and the first vertical rod gv1 form an inverted L-shape, and the second horizontal rod gh2 and the second vertical rod gv2 form an inverted L-shape. The first horizontal rod gh1 is located above the second horizontal rod gh2, and the first vertical rod gv1 is located outside the second vertical rod gv2, so that the inverted L-shape formed by the first horizontal rod gh1 and the first vertical rod gv1 is nested outside the inverted L-shape formed by the second horizontal rod gh2 and the second vertical rod gv2. The ends of the first vertical rod gv1 and the second vertical rod gv2 form a clamping portion CP for clamping the housing 2002 of the corresponding capacitor 2000. The lower surface of the first horizontal rod gh1 is formed with upper teeth Tu arranged horizontally, and the upper surface of the second horizontal rod gh2 is formed with lower teeth T1 arranged horizontally. The gear body T meshes with the upper teeth Tu and the lower teeth T1, forming a gear rack meshing engagement between the gear body T and the first and second horizontal rods gh1 and gh2. The linear reciprocating mechanism 38 also includes a transverse reciprocating motion unit 382, ​​which is fixedly connected to each first horizontal rod gh1 and is used to drive each first horizontal rod gh1 toward or away from each other along the first and second vertical rods gv1 and gv2 to clamp and release the corresponding capacitor housing 2002.

[0207] Specifically, if Figure 14 As shown, the transverse reciprocating motion unit 382 is a third cylinder, which includes a third cylinder body 382a and a third piston 382b. The third piston 382b can extend or retract into the third cylinder body 382a along the directions relative to each other of the first vertical rod gv1 and the second vertical rod gv2; the third piston 382b is connected to each first horizontal rod gh1 to drive each first horizontal rod gh1 along the first vertical rod gv1 and the second vertical rod gv2 to move closer to or away from each other to achieve clamping of the corresponding capacitor 2000 shell 2002.

[0208] Reference Figure 12 and Figure 14The linear reciprocating motion mechanism 38 also includes a lower plate 383, an upper plate 384, an upper connecting member 385, a lower connecting member 386, and a push member 387. The lower plate 383 is provided with a plurality of positioning slots 383a, each of which accommodates a corresponding first horizontal rod gh1, second horizontal rod gh2, and gear body T. The corresponding first vertical rod gv1 and second vertical rod gv2 are located outside the lower plate 383. The upper plate 384 is located above the lower plate 383 and is assembled with the lower plate 383. The upper connecting member 385 fixedly connects the third cylinder 382a to the upper plate 384. The lower connecting member 386 fixedly connects the third cylinder 382a to the lower plate 383. The pusher 387 fixedly connects the third piston 382 b and the first horizontal rods gh1 of the first clamping mechanism 20 , the second clamping mechanism 21 , the third clamping mechanism 22 , the fourth clamping mechanism 27 , the fifth clamping mechanism 29 , the sixth clamping mechanism 31 , the seventh clamping mechanism 33 and the eighth clamping mechanism 35 .

[0209] like Figure 12 and Figure 14 As shown, each positioning slot 383a extends through the lower plate 383 in a direction in which the first vertical rod gv1 and the second vertical rod gv2 are opposite each other. The linear reciprocating motion mechanism 38 also includes an inserting plate 388 having a plurality of through-holes 388a therein. Each through-hole 388a extends through the inserting plate 388 in a direction in which the first vertical rod gv1 and the second vertical rod gv2 are opposite each other. The inserting plate 388 is fixed to the lower plate 383, and each through-hole 388a corresponds to a corresponding positioning slot 383a of the lower plate 383. The linear reciprocating mechanism 38 also includes a plurality of first springs 389a and a plurality of connecting rods 389b. Each first spring 389a and connecting rod 389b corresponds to a second horizontal rod gh2. The first spring 389a is sleeved onto the connecting rod 389b, with one end of the first spring 389a resting against the insert plate 388, while the opposite end of the first spring 389a rests against the corresponding second horizontal rod gh2. One end of the connecting rod 389b passes through a corresponding through-hole 388a, while the other end of the connecting rod 389b is fixedly connected to the corresponding second horizontal rod gh2. The arrangement of the first springs 389a and connecting rods 389b ensures elasticity, flexibility, and stability in the clamping between the first and second horizontal rods gh1 and gh2.

[0210] Furthermore, if Figure 14 As shown, each connecting rod 389b includes a small outer diameter portion 389b1 and a large outer diameter portion 389b2. The outer diameter of the small outer diameter portion 389b1 is smaller than the diameter of the through-hole 388a, while the outer diameter of the large outer diameter portion 389b2 is larger than the diameter of the through-hole 388a, thereby acting as a position limiter. Furthermore, a truncated cone transition is formed between the small outer diameter portion 389b1 and the large outer diameter portion 389b2, thereby reducing hard contact between the large outer diameter portion 389b2 and the wall surface surrounding the through-hole 388a.

[0211] like Figure 12 and Figure 14 As shown, the push member 387 has a socket 387a, and the linear reciprocating motion mechanism 38 also includes a first intermediate block 389c and a second intermediate block 389d; the first intermediate block 389c has a main body 389c1 and a hook 389c2, the main body 389c1 has an assembly hole H, the assembly hole H is fixedly connected to the third piston 382b, and the hook 389c2 is inserted into and fixed to the socket 387a of the push member 387; the second intermediate block 389d has a through hole 389d1, the diameter of the through hole 389d1 is larger than the outer diameter of the third piston 382b, the second intermediate block 389d is for the third piston 382b to pass through the through hole 389d1 and the second intermediate block 389d is fixed to the end surface of the third cylinder body 382a; the upper connecting member 385 is fixedly connected to the top surface of the second intermediate block 389d; the lower connecting member 386 is fixedly connected to the lower part of the end surface of the second intermediate block 389d.

[0212] like Figure 13 and Figure 14 As shown, the first clamping mechanism 20 and the eighth clamping mechanism 35 each form paired clamping fingers CF at the ends of their respective first vertical rods gv1 and second vertical rods gv2, and the paired clamping fingers CF form a corresponding clamping portion CP. The paired clamping fingers CF of the first clamping mechanism 20 extend from the first vertical rods gv1 and gv2 of the first clamping mechanism 20 toward the loading device 1 (i.e., upstream); the paired clamping fingers CF of the eighth clamping mechanism 35 extend from the first vertical rods gv1 and gv2 of the eighth clamping mechanism 35 toward the flipping feeding device 4 (i.e., downstream). This improves the stability and convenience of clamping / transporting the housing 2002 of the capacitor 2000.

[0213] like Figure 14 As shown, the first clamping mechanism 20 forms two clamping fingers CF at the first vertical rod gv1 spaced apart from each other; the first clamping mechanism 20 forms two clamping fingers CF at the second vertical rod gv2 spaced apart from each other.

[0214] In one example, the paired clamping fingers CF of the first clamping mechanism 20 and the eighth clamping mechanism 35 are mirror images of each other.

[0215] In one example, the clamping portions CP of the second clamping mechanism 21, the third clamping mechanism 22, the fourth clamping mechanism 27, the fifth clamping mechanism 29, the sixth clamping mechanism 31, and the seventh clamping mechanism 33 are all directly formed by the ends of their respective first vertical rods gv1 and second vertical rods gv2. This reduces space occupancy and improves compactness. Furthermore, the clamping portions CP of the second clamping mechanism 21, the third clamping mechanism 22, the fourth clamping mechanism 27, the fifth clamping mechanism 29, the sixth clamping mechanism 31, and the seventh clamping mechanism 33 are all directly formed by the opposing V-grooves at the ends of their respective first vertical rods gv1 and second vertical rods gv2. This improves the clamping force and stability.

[0216] Reference Figure 22 and combined Figure 1 The flipping and feeding device 4 includes a clamping mechanism 40 , a flipping mechanism 41 and a pushing mechanism 42 .

[0217] The flipping mechanism 41 is used to flip the clamping mechanism 40 toward the lead straightening device 2, so that the clamping mechanism 40 can clamp the capacitor 2000 with its leads 2001 facing downward from the lead straightening device 2. The clamping mechanism 40 is also used to flip the clamping mechanism 40 toward the pushing mechanism 42, so that the capacitor 2000 held by the clamping mechanism 40 faces upward and is placed on the pushing mechanism 42. The pushing mechanism 42 receives the capacitor 2000 placed on it by the clamping mechanism 40 and is used to push the capacitor 2000 into the jig tray 5. As a result, the capacitor 2000 pushed into the jig tray 5 is now with its leads 2001 facing upward, ready for the next step of the glue injection operation.

[0218] Specifically, if Figure 23As shown, the clamping mechanism 40 includes two clamping arms 400, a spring 401, and a fourth air cylinder 402. Each clamping arm 400 has a clamping portion 400a, a gear portion 400b, and a handle portion 400c. The gear portions 400b of the two clamping arms 400 are meshed with each other, and the spring 401 is located between the clamping portions 400a and the gear portions 400b of the clamping arms 400 and connects the two clamping arms 400. The fourth air cylinder 402 has a fourth cylinder body 402a and a fourth piston 402b. The fourth piston 402b can enter and exit the fourth cylinder body 402a. The fourth piston 402b is used for: when the clamping mechanism 40 is flipped over to the lead straightening device 2 by the flipping mechanism 41 to receive the capacitor 2000 at the lead straightening device 2, the fourth piston 402b extends away from the fourth cylinder 402a and pushes the handle 400c of one of the clamping arms 400 to open the clamping parts 400a of the two clamping arms 400 to accommodate the capacitor 2000 at the lead straightening device 2, and retracts toward the fourth cylinder 402a to release the pushing pressure, and the clamping parts 400a of the two clamping arms 400 are brought together by the restoring force of the spring 401 to clamp the capacitor 2000 at the lead straightening device 2 accommodated, thereby The clamping mechanism 40 completes clamping the capacitor 2000 at the lead straightening device 2; and when the clamping mechanism 40 is flipped by the flipping mechanism 41 to above the pushing mechanism 42 to release the clamped capacitor 2000, the fourth piston 402b extends away from the fourth cylinder 402a and pushes the handle 400c of one of the clamping arms 400 to open the clamping parts 400a of the two clamping arms 400 to release the capacitor 2000 clamped by the clamping mechanism 40 to the pushing mechanism 42 and retract toward the fourth cylinder 402a to release the pushing pressure, and the clamping parts 400a of the two clamping arms 400 are brought together through the restoring force of the spring 401.

[0219] Specifically, if Figure 23 Shown and combined Figure 22The flipping mechanism 41 includes a mounting base 410, a gear 411, a rack 412, a connecting shaft 413 and a connecting handle 414. The mounting base 410 has a mounting groove 410a. The gear 411 and the rack 412 are installed in the mounting groove 410a. The gear 411 and the rack 412 are engaged with each other. One end of the rack 412 is fixedly connected to the wire straightening device 2 so that the rack 412 reciprocates with the linear reciprocating motion of the wire straightening device 2, thereby driving the gear 411 to rotate in the opposite direction. The connecting shaft 413 is cylindrical. The connecting shaft 413 is fixed through the gear 411 and is fixedly connected to one end of the connecting handle 414 so that the connecting handle 414 can rotate with the gear 411. The other end of the connecting handle 414 is connected to the gear portion 400b of the two clamping arms 400 so that the two clamping arms 400 can flip in opposite directions as the gear 411 rotates in opposite directions. The gear portions 400b of the two clamping arms 400 are pivotally connected to the other end of the connecting handle 414, enabling the two meshed gear portions 400b to rotate relative to each other. The pivot rod of the pivotal connection is not shown. The fourth piston 402b of the fourth cylinder 402 can freely extend and retract through the mounting slot 410a and the connecting shaft 413, thereby fully utilizing the connecting shaft 413 and improving the compactness of the structure.

[0220] like Figure 22 and Figure 23 As shown, the flip mechanism 41 further includes a support base 415, which is fixedly connected to one side of the connecting handle 414 of the mounting base 410. Thus, the space is fully utilized, the stability of the movement of the gear 411 and the rack 41 is improved, and the rotation of the connecting handle 414 is limited.

[0221] like Figure 22 and Figure 23 As shown, the flipping mechanism 41 further includes a connecting plate 416 , and the one end of the rack 412 is fixedly connected to the lead straightening device 2 via the connecting plate 416 .

[0222] Reference Figure 22 and Figure 23The pushing mechanism 42 includes a material receiving seat 420, a push block 421, and a connecting rod 422. The material receiving seat 420 is provided with a chute 420a and a gap 420b that is transversely connected to the chute 420a. The chute 420a is used to accommodate the capacitor 2000 and the push block 421 transported by the clamping mechanism 40. The gap 420b is elongated. The push block 421 can slide in the chute 420a. One end of the connecting rod 422 is fixedly connected to one end of the rack 412, while 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 push block 421. Therefore, the connecting rod 422 drives the push block 421 to reciprocate linearly within the chute 420a as the rack 412 reciprocates linearly. During operation: when the rack 412 moves toward the lead straightening device 2, the flipping mechanism 41 flips the clamping mechanism 40 toward the pushing mechanism 42, and the rack 412 drives the connecting rod 422 and the pushing block 421 to move toward the lead straightening device 2, and the clamping mechanism 40 places the capacitor 2000 with the lead 2001 facing upward on the side of the push block 421 facing the jig disk 5 in the chute 420a; when the rack 412 moves toward the jig disk 5, the flipping mechanism 41 flips the clamping mechanism 40 toward the lead straightening device 2, and the rack 412 drives the connecting rod 422 and the pushing block 421 to move toward the jig disk 5, and the pushing block 421 pushes the capacitor 2000 with the lead 2001 facing upward from the chute 420a to the jig disk 5.

[0223] like Figure 23 As shown, both ends of the gap 420b in the directions opposite to the jig plate 5 and the lead straightening device 2 are closed, thereby limiting the extreme positions of the movement of the connecting rod 422 by the closed ends.

[0224] like Figure 23 As shown, the end of the push block 421 facing the fixture plate 5 is formed with a V-shaped recessed portion 421a projected in the vertical direction D1. The recessed portion 421a forms a good fit with the circular surface of the housing 2002 of the capacitor 2000, increasing the smoothness of the push of the push block 421.

[0225] like Figure 23 As shown, flanges 421b are formed on both sides of the bottom of the push block 421; a recessed portion 420c is formed at the bottom of the chute 420a of the material receiving seat 420, and the flanges 421b slide in conjunction with the recessed portion 420c, thereby increasing the stability of the push of the push block 421.

[0226] like Figure 23 As shown, the chute 420a passes through the material receiving seat 420 in the direction opposite to the fixture plate 5 and the lead straightening device 2, thereby increasing the area for placing the capacitor 2000 in the chute 420a.

[0227] Reference Figure 28 Combined with Figure 27 and Figure 1The fixture tray 5 includes a tray body 50, which has a plurality of spaced, parallel and parallel receiving grooves 501. Each receiving groove 501 is elongated and has a first end 501a and a second end 501b. The first end 501a faces the flip feeding device 4 (i.e., faces upstream) and is open, and the second end 501b is closed. Each receiving groove 501 accommodates a row of capacitors 2000 with the leads 2001 facing upward. During operation, the first end 501a of a receiving groove 501 that is not full of capacitors 2000 is adjacent to and aligned with the slide groove 420a of the receiving seat 420.

[0228] In one example, the jig tray 5 has chamfers at the open first ends 501 a of the receiving grooves 501 , thereby facilitating the capacitors 2000 to enter the receiving grooves 501 .

[0229] like Figure 28 As shown, the tray body 50 further includes side walls 502 on both outer sides of the plurality of receiving slots 501 in the parallel direction. The side walls 502 are provided with slots 502a at the ends adjacent to the flip feeder 4 (i.e., adjacent upstream). The fixture tray 5 also includes a retaining bar 51. The retaining bar 51 includes a main body 510 and two protrusions 511. The two protrusions 511 protrude downward from both ends of the main body 510. The two protrusions 511 are respectively inserted into the two slots 502a, so that the main body 510 of the retaining bar 51 prevents the capacitors 2000 installed in the receiving slots 501 of the tray body 50 from falling out of the second end 501b of each receiving slot 501. It is noted that the retaining bar 51 is removed when the plurality of receiving slots 501 are not fully filled with capacitors 2000 and the glue injection is not completed.

[0230] Reference Figure 24 、 Figure 25 and combined Figure 1 The glue injection device 6 includes a glue supply mechanism 61, a glue dispensing valve 62, and a lifting mechanism 63. The lifting mechanism 63 is connected to the glue supply mechanism 61 and the glue dispensing valve 62 to drive the glue supply mechanism 61 and the glue dispensing valve 62 to descend to the jig tray 5 above the capacitor 2000 that has just been received. The glue supply mechanism 61 is used to mix glue A and glue B and then provide the mixed glue AB to the glue dispensing valve 62. The glue dispensing valve 62 is used to inject the received glue AB onto the top of the inner side of the top edge of the housing 2002 of the capacitor 2000, covering the top.

[0231] Specifically, if Figure 24 As shown, the glue supply mechanism 61 includes glue barrel A 610, glue barrel B 611, a twin-screw valve 612, and a mixing tube 613. Glue barrel A 610 holds glue A. Glue barrel B 611 holds glue B. Twin-screw valve 612 supplies glue A and glue B from glue barrels A 610 and B 611, respectively, to mixing tube 613. Mixing tube 613 receives and mixes glue A and glue B supplied by twin-screw valve 612.

[0232] In one example, the dispensing valve 62 is a needle valve.

[0233] Specifically, if Figure 24 and Figure 25 As shown, the lifting mechanism 63 includes a motor 630, a screw-nut transmission module 631, a sliding member 632, and a connecting plate 633. The motor 630 is connected to the screw-nut transmission module 631, which is used to convert the rotation of the motor 630 into linear reciprocating motion in the up-down direction D1. The sliding member 632 is connected to the screw-nut transmission module 631 and the connecting plate 633. The glue supply mechanism 61 and the glue dispensing valve 62 are fixed to the connecting plate 633.

[0234] like Figure 24 and Figure 25 As shown, the glue injection device 6 further includes a lead wire guide mechanism 64 for guiding the lead wire 2001 therein. Thus, compared with the prior art gantry three-axis glue injection machine, the risk of collision with the lead wire 2001 of the capacitor 2000 during glue injection can be avoided.

[0235] Specifically, if Figure 25 As shown, the wire guide mechanism 64 includes a connecting portion 640 and a guide portion 641. The connecting portion 640 connects the guide portion 641 to the lifting mechanism 63. The guide portion 641 includes a guide groove 641a extending along the direction in which the jig plate 5 and the flip feeder 4 face each other (i.e., along the direction in which the jig plate 5 and the upstream face each other). The guide groove 641a has a gradually increasing trumpet-shaped opening on the side facing the flip feeder 4 (i.e., facing upstream). During the glue injection operation of the glue injection device 6, the two leads 2001 of a capacitor 2000 enter the guide groove 641a through the gradually increasing trumpet-shaped opening, and the needle 621 of the glue dispensing valve 62 is located on the outside of the gradually increasing trumpet-shaped opening in a direction perpendicular to the direction in which the jig disk 5 and the flip feeding device 4 are relative to each other (that is, the direction in which the jig disk 5 and the upstream are relative to each other). After the glue injection is completed, the capacitor 2000 to be injected is pushed through the guide groove 641a into the jig disk 5 by the push of the next capacitor 2000 to be injected sent from the upstream (that is, sent by the upstream flip feeding device 4).

[0236] Reference Figure 24 and Figure 25The capacitor glue injection device 1000 also includes (i.e., the glue injection module also includes) an anti-fall device 7. This device is used by the glue injection device 6 to block the housing 2002 of the capacitor 2000 from the side of the capacitor 2000 facing away from the flip feed device 4 (i.e., away from the upstream) when injecting glue into a capacitor 2000, thereby preventing the capacitor 2000 from tipping over during glue injection. Compared to the prior art method of inserting capacitors into the grid of a jig tray, the use of the anti-fall device 7 not only eliminates manual operation but also facilitates the positioning of the capacitor 2000.

[0237] Specifically, if Figure 24 As shown, the anti-fall device 7 includes a reciprocating linear motion mechanism 70, a connecting plate 71 and a baffle 72, the baffle 72 is connected to the connecting plate 71, and the connecting plate 71 is connected to the reciprocating linear motion mechanism 70: the reciprocating linear motion mechanism 70 is used to drive the connecting plate 71 and the baffle 72 to reciprocate along the directions relative to each other between the jig disk 5 and the flip feeding device 4 (that is, along the directions relative to each other between the jig disk 5 and the upstream), so that the baffle 72 blocks the shell 2002 of the capacitor 2000 from the side of the capacitor 2000 away from the flip feeding device 4 (that is, away from the upstream) to prevent the capacitor 2000 from falling over during glue injection.

[0238] Furthermore, if Figure 24 As shown, the reciprocating linear motion mechanism 70 includes a motor 701, a screw-nut transmission unit 702, and a sliding block 703. The motor 701 is connected to the screw-nut transmission unit 702, and the screw-nut transmission unit 702 is used to convert the rotation of the motor 701 into a linear reciprocating motion along the directions relative to each other between the fixture plate 5 and the flip feed device 4. The sliding block 703 is connected to the screw-nut transmission unit 702 and the connecting plate 71. The use of the screw-nut transmission unit 702 can improve the displacement accuracy of the connecting plate 71 and thus improve the displacement accuracy of the baffle 72. In one example, the baffle 72 and the connecting plate 71 are a single-piece plate, thereby improving the overall rigidity of the baffle 72 and the connecting plate 71 and enhancing the ability to prevent the capacitor 2000 from tipping over during glue injection.

[0239] Reference Figure 27 and combined Figure 1 The capacitor injection molding apparatus 1000 further includes (i.e., the injection module also includes) a jig tray shifting device 8. When a row of injected capacitors 2000 is filled in a receiving slot 501 of the jig tray 5, the jig tray shifting device 8 is used to drive the jig tray 5 in a direction in which the multiple receiving slots 501 are aligned side by side, so that adjacent empty receiving slots 501 are aligned with the flip feeder 4 (i.e., upstream). This allows for automated arrangement of injected capacitors 2000 on the jig tray 5.

[0240] Specifically, if Figure 27As shown, the jig tray line change device 8 includes a lower support plate 80, an upper support plate 81, a linear motion mechanism 82, a plurality of guide rails 83 and a plurality of slides 84. The upper support plate 81 is used to position and support the jig tray 5. The lower support plate 80 is used to support the linear motion mechanism 82, a plurality of guide rails 83, a plurality of slides 84, the upper support plate 81 and the jig tray 5. The linear motion mechanism 82 is connected to the upper support plate 81 from below to drive the upper support plate 81 together with the jig tray 5 to move in the direction of the plurality of receiving slots 501 side by side so that the adjacent empty receiving slots 501 are aligned with the flip feeding device 4 (i.e., upstream). The plurality of guide rails 83 are distributed on both sides of the linear motion mechanism 82 and fixed on the lower support plate 80. The plurality of slides 84 are assembled corresponding to the plurality of guide rails 83 to form corresponding sliding pairs, and the plurality of slides 84 are fixedly connected to the upper support plate 81.

[0241] Further, if Figure 27 As shown, the linear motion mechanism 82 includes a motor 821, a screw-nut transmission mechanism 822, and a slider 823. The motor 821 is connected to the screw-nut transmission mechanism 822, which converts the rotation of the motor 821 into linear reciprocating motion along the parallel arrangement of the plurality of receiving slots 501. The slider 823 is connected to the screw-nut transmission mechanism 822 and the upper support plate 81. The use of the screw-nut transmission mechanism 822 helps ensure the displacement accuracy of the fixture plate 5.

[0242] Reference Figure 1 The capacitor glue injection device 1000 further includes (ie, the glue injection module further includes) a glue storage device 9, which includes a glue storage tank 90 for storing glue A and a glue storage tank 91 for storing glue B. The glue injection module further includes a glue storage device 9.

[0243] Reference Figure 1 The capacitor glue injection equipment 1000 also includes a control device C. The control device C is used to communicate with the feeding device 1, the lead straightening device 2, the flip feeding device 4, the glue injection device 6, the anti-reversal device 7, and the jig tray line changing device 8 and control the actions of the feeding device 1, the lead straightening device 2, the flip feeding device 4, the glue injection device 6, the anti-reversal device 7, and the jig tray line changing device 8. The control device C includes a touch screen C1, which is used to display the status and process control parameters of the feeding device 1, the lead straightening device 2, the flip feeding device 4, the glue injection device 6, the anti-reversal device 7, and the jig tray line changing device 8.

[0244] It should be noted that the capacitor glue injection device 1000 disclosed in the present invention is not only applicable to the case where the capacitor 2000 is a supercapacitor, but is also applicable to any other case where a capacitor with double leads needs to be injected with glue.

[0245] The above detailed description is used to describe a number of exemplary embodiments, but this document is not intended to be limited to the explicitly disclosed combinations. Therefore, unless otherwise stated, the various features disclosed herein may be combined to form multiple additional combinations that are not shown for the sake of brevity.
