Utility Model Content

[0003] The utility model aims to provide a reverse placement identification mechanism for a feeding device, which can eliminate a reverse base and has the advantages of ensuring product quality, saving materials and reducing production costs.

[0006] The identification and reverse placement mechanism is installed on the track; the identification and reverse placement mechanism includes an identification window and a rotating gear;

[0007] The identification window is arranged at the top of the groove and communicates with the outside world;

[0008] The rotating gear is rotatably mounted outside the identification window, and a plurality of teeth are arranged evenly spaced in the circumferential direction on the outer peripheral side wall of the rotating gear; there is a circumferential gap between adjacent teeth, and the circumferential gap is used for the middle convex part of the base to movably extend into;

[0009] The outer end of the tooth rotates through the identification window and rotates into the groove in the track;

[0010] When the base is transported in the forward direction, the outer ends of the teeth are located in the side recessed portion; when the base is transported in the reverse direction, the outer ends of the teeth abut against and clamp the bottom of the base.

[0011] Furthermore, the outer end of the tooth has a minimum distance from the bottom of the groove. When the base is transported in the forward direction, the minimum distance is greater than the distance between the bottom surface of the side recess of the base and the bottom of the groove. When the base is transported in the reverse direction, the minimum distance is less than the distance between the bottom of the base and the bottom of the groove. The circumferential chord length of the outer end of the tooth is less than the distance between the middle convex parts of two adjacent bases. The outermost chord length of the circumferential gap is greater than the length of the middle convex part of the base along the transporting direction, and the outermost chord length is also less than the bottom length of the base along the transporting direction.

[0012] Furthermore, the identification and reverse placement mechanism also includes a gear seat, which is connected to the track and has a bearing; the rotating gear sleeve is placed on the outside of the bearing.

[0013] Furthermore, the gear seat is provided with a bearing mounting hole, a rotating shaft is passed through and installed in the bearing mounting hole, and the bearing sleeve is placed on the rotating shaft.

[0014] Furthermore, the identification and reverse placement mechanism also includes an exclusion mechanism; the exclusion mechanism includes an outlet and a baffle; the outlet is arranged on the side wall of the track adjacent to the identification window, the outlet connects the inner groove of the track and the outside world, and the outlet is used for a base to pass through; the baffle movably blocks the outlet.

[0015] Furthermore, the ejection mechanism also includes a push rod; a push rod through hole is provided on the side wall of the track on the other side relative to the discharge port, and the push rod through hole connects the inner channel of the track and the outside world; the inner end of the push rod can reciprocate through the push rod through hole to push against the base and discharge from the discharge port; and the outer end of the push rod is located outside the track.

[0016] Furthermore, the exclusion mechanism also includes a push plate, a push rod and a spring; a track through hole is provided on the track, and the axis of the track through hole is parallel to the axis of the push rod through hole; the push rod is reciprocatingly arranged in the track through hole, one end of the push rod is connected to the baffle, and the other end of the push rod is connected to the push plate, and at the same time, the outer end of the push rod is also connected to the push plate; the spring is sleeved on the outer periphery of the push rod, and the two ends of the spring are respectively against the outer wall of the track and the push plate; the push plate is used to drive the push rod and the push rod to slide synchronously, so as to drive the baffle to open the discharge outlet while allowing the push rod to push the base out of the discharge outlet; the spring provides elastic force for resetting the baffle and the push rod.

[0017] Furthermore, the track includes a track body and a track side plate; the groove is recessed on the side of the track body, and the track side plate is detachably locked to the side wall of the track body and covers the groove.

[0019] Furthermore, the channel of the track includes an intermediate conveying channel that utilizes gravity to convey the base from top to bottom; and the reverse identification mechanism is installed in the upper middle part of the intermediate conveying channel.

[0020] After adopting the above technical solution, when the base in the track groove is transported in the forward direction, the middle convex part and the side concave part of the base are both facing the groove top. When the base passes the groove position corresponding to the identification window, the teeth of the rotating gear can rotate from the identification window into the groove and be located in the side concave part. Therefore, the teeth will not affect the normal transportation of the base. At the same time, the middle convex part of the base that is continuously transported can also move the teeth located in the groove out of the identification window, and make the next tooth enter the identification window to identify the next base. At the same time, since the bases in the groove are transported closely, as long as the side concave part of the first base corresponds to the teeth, the bases transported in the forward direction can make the side concave part correspond to the teeth, and make the middle convex part located in the circumferential gap to avoid interference between the middle convex part and the outer end of the teeth.

[0021] When the base in the groove is transported in the reverse direction, the bottom of the base faces the top of the groove. Therefore, when the base in the reverse direction is transported to the identification window, the bottom of the base will interfere with the teeth, causing the two to get stuck. This reminds the staff that the base in the track is placed upside down and corrects it in time. This ensures the quality of the produced base, improves the product qualification rate, and saves production costs. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0032] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application described and shown in the drawings here can be arranged and designed in various different configurations.

[0033] like Figures 2 to 8 As shown, the utility model has an inverted identification mechanism B of a feeding device A, which is used to automatically identify whether the base 1 transported by the track 2 in the feeding device A is inverted, and automatically stop the transportation of the base 1 to remind the staff to check in time to avoid the inverted base 1 from entering the next process, so as to save materials and reduce costs.

[0034] In this embodiment, the previous process of the loading device A can be connected to a vibration plate (not shown), and the next process can be connected to a welding assembly (not shown). The welding assembly may include a turntable with clamping claws for clamping the base 1, and the loading device A may include a track 2.

[0035] See also Figure 6 The groove 21 of the track 2 of the feeding device A has a groove bottom 211 and a groove top 212, and a plurality of bases 1 are transported in sequence along the groove 21 in the track 2; the top of the base 1 has a middle convex portion 11, and the two sides of the middle convex portion 11 are side concave portions 12 respectively.

[0036] When the base 1 is transported forward, the bottom 13 of the base 1 is against the groove bottom 211, and the middle convex part 11 and the side concave part 12 on the top of the base 1 are both facing the groove top 212. When transported backward, the middle convex part 11 on the top of the base 1 is against the groove bottom 211, and the bottom 13 of the base 1 is facing the groove top 212.

[0037] See also Figure 4 and Figure 5 The reverse identification mechanism B is installed on the track 2; the reverse identification mechanism B includes an identification window 3 and a rotating gear 4; and is used to identify whether the base 1 transported in the track 2 is reversed.

[0038] The identification window 3 is disposed at the groove top 212 of the groove 21 and communicates with the outside world;

[0039] The rotating gear 4 is rotatably mounted on the outer side of the identification window 3, and a plurality of teeth 41 are arranged evenly spaced in the circumferential direction on the outer peripheral side wall of the rotating gear 4; a circumferential gap 42 is provided between adjacent teeth 41, and the circumferential gap 42 is used for the middle convex portion 11 of the base 1 to movably extend therein;

[0040] The outer end 411 of the tooth rotates through the identification window 3 and rotates to extend into the groove 21 in the track 2;

[0041] When the base 1 is transported in the forward direction, the outer end 411 of the tooth is located in the side recess 12 ; when the base 1 is transported in the reverse direction, the outer end 411 of the tooth abuts against and clamps the bottom 13 of the base 1 .

[0042] Thus, when the base 1 in the groove 21 of the track 2 is transported in the forward direction, the middle convex portion 11 and the side concave portion 12 of the base 1 are both facing the groove top 212. When the base 1 passes the groove 21 position corresponding to the identification window 3, the teeth 41 of the rotating gear 4 can rotate from the identification window 3 into the groove 21 and be located in the side concave portion 12. Therefore, the teeth 41 will not affect the normal transportation of the base 1. At the same time, the middle convex portion 11 of the base 1 that is continuously transported can also move the teeth 41 located in the groove 21 to rotate out of the identification window 3, and make the next tooth 41 rotate into the identification window 3 to identify the next base 1. At the same time, since each base 1 in the groove 21 is transported closely, as long as the side concave portion 12 of the first base 1 corresponds to the teeth 41, the base 1 transported in the forward direction can make the side concave portion 12 correspond to the teeth 41, and make the middle convex portion 11 located in the circumferential gap 42, so as to avoid interference between the middle convex portion 11 and the outer end 411 of the teeth.

[0043] When the base 1 in the groove 21 is transported in the reverse direction, the bottom 13 of the base 1 faces the groove top 212. Therefore, when the reverse base 1 is transported to the identification window 3, the bottom 13 of the base 1 will interfere with the teeth 41, causing the two to be stuck, thereby reminding the staff that the base 1 in the track 2 is placed upside down and correcting it in time.

[0044] Specifically, Figure 6 As shown, the outer end 411 of the tooth has a minimum spacing H1 with the groove bottom 211. When the base 1 is transported in the forward direction, the minimum spacing H1 is greater than the spacing between the bottom surface of the side recess 12 of the base 1 and the groove bottom 211, so as to avoid interference between the tooth 41 and the bottom surface of the side recess 12; and when the base 1 is transported in the reverse direction, the minimum spacing H1 is smaller than the spacing between the bottom 13 of the base 1 and the groove bottom 211, so as to timely and accurately identify the reversed base 1.

[0045] The circumferential chord length S1 of the outer end 411 of the tooth is smaller than the spacing between the middle convex portions 11 of two adjacent bases 1, that is, the outer end 411 of the tooth can extend into the side recess 12; the outermost chord length S2 of the circumferential gap 42 is larger than the length of the middle convex portion 11 of the base 1 along the conveying direction, so that the middle convex portion 11 can extend therein, and the outermost chord length S2 is also smaller than the length of the bottom 13 of the base 1 along the conveying direction, ensuring that the outer end 411 of the tooth can resist the bottom 13 of the base 1.

[0046] like Figures 2 to 4 The identification and reverse mechanism B also includes a gear seat 5, which is connected to the track 2, and a bearing 6 is provided on the gear seat 5; the rotating gear 4 is sleeved on the outer side of the bearing 6, so that the rotating gear 4 can rotate smoothly.

[0047] Specifically, Figure 4 The gear seat 5 is provided with a bearing mounting hole 51, a rotating shaft 52 is installed on the bearing mounting hole 51, and the bearing 6 is sleeved on the rotating shaft 52. The rotating shaft 52 can be a screw 521, which passes through the bearing 6 and the bearing mounting hole 51 and is locked with the gear seat 5 through a nut 522.

[0048] At the same time, in order to facilitate the removal of the base 1 that is placed upside down; Figure 2 , Figure 4 , Figure 8 and Fig. 9As shown, the identification reversed placement mechanism B of this embodiment further includes an exclusion mechanism 7; the exclusion mechanism 7 includes an outlet 71 and a baffle 72; the outlet 71 is arranged on the track side wall 22 adjacent to the identification window 3, the outlet 71 connects the groove 21 in the track 2 with the outside, and the outlet 71 is used for a base 1 to pass through; the baffle 72 movably blocks the outlet 71. Therefore, when it is found that a base 1 is reversed, the baffle 72 can be opened to discharge the base 1 stuck by the teeth 41 of the rotating gear 4 out of the groove 21.

[0049] In order to facilitate the discharge of the base 1 from the channel 21 , the discharge mechanism 7 further includes a push rod 73 .

[0050] A push rod through hole 74 may be provided on the track side wall 22 on the other side relative to the discharge port 71, and the push rod through hole 74 connects the groove 21 in the track 2 with the outside; the push rod inner end 731 may reciprocate through the push rod through hole 74 to push against the base 1 to be discharged from the discharge port 71; and the push rod outer end 732 is located outside the track 2. Therefore, after opening the baffle 72, the push rod inner end 731 may be manipulated to push the reversed base 1 out of the groove 21 from the discharge port 71 by manipulating the push rod outer end 732, and the operation is convenient.

[0051] In this embodiment, the ejection mechanism 7 further includes a push plate 75, a push rod 76 and a spring 77; the track 2 is provided with a track through hole 78, the axis of which is parallel to the axis of the ejector through hole 74; the push rod 76 is reciprocatingly arranged in the track through hole 78, one end of the push rod 76 is connected to the baffle 72, the other end of the push rod 76 is connected to the push plate 75, and at the same time, the outer end 732 of the ejector is also connected to the push plate 75; the spring 77 is sleeved on the outer periphery of the push rod 76, and the two ends of the spring 77 are respectively against the outer wall of the track 2 and the push plate 75; the push plate 75 is used to drive the push rod 76 and the ejector 73 to slide synchronously, so as to drive the baffle 72 to open the discharge port 71, and at the same time, the ejector 73 ejects the base 1 from the discharge port 71; the spring 77 provides elastic force for the baffle 72 and the ejector 73 to reset. In this way, the efficiency of ejecting the reversed base 1 can be greatly improved, so as to improve the working efficiency and enable the base 1 to resume normal forward conveying as soon as possible.

[0052] like Figure 2 The track 2 includes a track body 24 and a track side plate 25 ; the groove 21 is recessed on the side of the track body 24 , and the track side plate 25 is detachably locked to the side wall of the track body 24 and blocks the groove 21 .

[0053] At the same time, an observation slot 23 may be formed between the track side plate 24 and the slot top 212 of the slot 21, the observation slot 23 is connected to the outside and the slot 21, and is used to reveal the middle convex portion 11 of the base 1 during forward transportation in the slot 21. It is also convenient for the staff to observe whether the base 1 in the slot 21 is placed upside down.

[0054] like Figure 5 and Figure 6 In this embodiment, the channel 21 of the track 2 includes an intermediate conveying channel 213 for conveying the base 1 from top to bottom by gravity; in this embodiment, the intermediate conveying channel 213 is taken as an example by removing the middle part of the upper and lower parts of the track 2; the reverse identification mechanism B is installed in the upper middle part of the intermediate conveying channel 213. Without external force, the base 1 sliding down with gravity can simultaneously turn the rotating gear 4 to rotate if it is conveyed in the forward direction; if it is in the reverse direction, the rotating gear 4 only needs to overcome gravity to clamp the base 1, so that the structure of the utility model is stable and reliable.
