Description

TECHNICAL FIELD

[0001] The application relates to the field of feeding equipment, in particular to a feeding device for a magnetic circuit assembling machine for producing a loudspeaker. BACKGROUND

[0002] In the production process of a loudspeaker, a feeding device is generally used to convey materials to a specified position and then the materials are taken down by a mechanical hand. In this process, the mechanical hand may be empty, so that the materials on the carrying table cannot be taken down in time and enter the next link, which not only affects the production of the next link, but also causes waste of materials. SUMMARY

[0003] In order to solve the problem that the existing feeding device cannot replace the carrying table which is not empty, the application provides a feeding device for a magnetic circuit assembling machine for producing a loudspeaker, which comprises a horizontally arranged frame body, a conveying channel is arranged in the length direction of the frame body, a plurality of driving rollers are rotationally connected in the conveying channel, a driving assembly for driving the plurality of driving rollers to rotate is arranged on the frame body, and a plurality of carrying tables are sequentially arranged in the length direction in the conveying channel.

[0004] The feeding device further comprises a replacement mechanism, and the replacement mechanism comprises a mounting frame and a replacement part.

[0005] The replacement part comprises a sliding rail mounted on the mounting frame in the width direction of the conveying channel, and a push rod slidingly arranged on the sliding rail, and a plurality of positioning blocks are integrally arranged on the upper surface of the push rod along the axis of the push rod; a push mechanism one for pushing the sliding rail to reciprocate up and down is arranged on the mounting frame, and a push mechanism two for driving the push rod to reciprocate in the sliding rail is arranged on the sliding rail.

[0006] The conveying channel below the empty load detector is provided with a clearance on both sides, the replacement part penetrates through the two clearances, and the replacement part is located below the carrying table.

[0007] A positioning groove adapted to the positioning blocks is formed in the lower surface of the carrying table, the carrying table is arranged at the positioning blocks on the push rod between the frame body and the first end of the replacement part, and the positioning blocks are inserted into the positioning groove of the push rod.

[0008] By adopting the above scheme, the feeding device runs in a progressive feeding mode. That is, the driving roller drives a plurality of bearing tables to move a distance in the conveying channel and then pause. During the pause, other devices such as a mechanical hand operate the materials on the bearing tables. Then the driving roller drives the plurality of bearing tables to continue moving and then pause. The feeding is realized in the above manner. During this process, when the detector detects that there is material on the bearing table directly below, the control center controls the pushing mechanism to push the replacement part upward. During the process, the positioning block on the push rod is inserted into the positioning groove of the bearing table, and the bearing table is pushed upward. Then the second pushing mechanism is started to drive the push rod to move toward the tail end of the replacement part, so that the bearing table moves to the side away from the mounting rack of the frame body, and a new bearing table is located in the vacant position in the conveying channel. At this time, the second pushing mechanism is paused, and the first pushing mechanism is started again to pull the replacement part downward. The new bearing table enters the vacant position in the conveying channel and is placed on the driving roller. Then the replacement part continues to move downward until the positioning block is separated from the positioning groove, and the first pushing mechanism is paused. The bearing table replacement is completed. Further, the sliding rail includes a body which is a rectangular channel steel. A connecting edge is integrally arranged in the body along the length direction. A connecting groove is arranged on the push rod. The connecting edge extends into the connecting groove and is in sliding connection with the push rod.

[0009] By adopting the above scheme, the displacement of the push rod in the vertical direction can be limited, so that the push rod is more stable.

[0010] Further, the bracket is fixedly connected to the sliding rail.

[0011] By adopting the above scheme, the empty load detector moves upward synchronously with the replacement part during the upward movement of the replacement part, reducing the mutual interference between the detector and the replacement part.

[0012] Further, the push rod includes a plurality of push parts, and a plurality of positioning blocks correspond to the plurality of push parts one by one.

[0013] The tail end of the replacement part is provided with a storage mechanism. The storage mechanism includes a base and a storage disc rotatably connected to the base, and a driving motor for driving the storage disc to rotate. A plurality of storage parts with a polygonal cross section are fixedly installed on the storage disc. The plurality of storage parts are arranged in a circular array on the storage disc. A storage hole adapted to the storage part is formed on the push part along the axis direction of the push part. The storage part in the storage position is aligned with the storage hole on the push part when the first pushing mechanism lifts the replacement part to the highest position.

[0014] A button connected with the control center is arranged on one side of the storage disc of the storage part. The button is pressed when the push part slides to the storage part. The driving motor drives the next storage part to enter the storage position.

[0015] By adopting the above scheme, after the pushing mechanism one pushes the replacement part upward to the highest position, the driving mechanism two drives the pushing rod to move in the direction of the tail end of the replacement part, the pushing part carrying the bearing table gradually slides onto the storage part, and when the pushing part completely separates from the sliding track, the pushing part abuts and presses the button in the storage position. At this time, the control center drives the storage disc to rotate by a fixed angle to make the next storage part enter the storage position. Further, the storage of the pushing part is continuously realized, and the overall space occupation of the replacement mechanism is reduced.

[0016] Further, the storage part is fixedly connected with a connecting part having a circular cross section, the connecting part passes through the storage disc and is rotationally connected with the storage disc, and one end of the connecting part passing through the storage disc is fixedly installed with a gravity part.

[0017] By adopting the above scheme, the gravity part can prevent the bearing table from rotating with the storage disc under the action of its own gravity.

[0018] Further, the storage mechanism is provided with two groups of storage mechanisms one and two, respectively.

[0019] The storage mechanism one is arranged at the tail end of the replacement part, and the storage mechanism two is arranged at the head end of the replacement part.

[0020] The pushing part is arranged on a plurality of storage parts on the storage mechanism two, and the bearing table is arranged on the pushing part. When the pushing mechanism one lifts the replacement part to the highest position, the pushing part in the storage position is aligned with the sliding track.

[0021] The storage part in the storage mechanism includes a base part and a driving part. The base part is a tubular structure with a rectangular cross section and two open ends, the base part is connected with the connecting part, the connecting part is provided with a through hole in communication with the base part, and the driving part is a rod-shaped structure with a rectangular cross section. One end face of the driving part is provided with a sliding groove matched with the base part, and the base part extends into the sliding groove and is in sliding connection with the driving part.

[0022] A pushing part is arranged on the side of the storage part away from the sliding track, the pushing part is a pneumatic cylinder or a hydraulic cylinder, and the piston rod of the pushing part is aligned with the through hole in the storage position.

[0023] By adopting the above scheme, when the replacement part lifts the bearing table in the conveying channel to the highest position, the sliding rail is aligned with the pushing part on the receiving part in the receiving mechanism, the piston rod of the pushing part extends into the base part in the receiving position and contacts the driving part, then the piston rod of the pushing part continues to extend and pushes the driving part to move towards the sliding rail, and the ejecting part on the receiving part is sent into the sliding rail.

[0024] Further, the end of the piston rod of the pushing part is fixed with an auxiliary magnet.

[0025] By adopting the above scheme, the auxiliary magnet forms adsorption on the driving part, so that the pushing part drives the driving part to reset during retraction.

[0026] Further, the end of the piston rod of the pushing part is fixed with an auxiliary magnet.

[0027] By adopting the above scheme, the auxiliary magnet forms adsorption on the driving part, so that the pushing part drives the driving part to reset during retraction.

[0028] Further, when the ejecting part is located in the sliding rail, the connecting magnet is located at one end of the ejecting part facing the receiving mechanism.

[0029] By adopting the above scheme, when the ejecting part is located on the receiving part, it can be adsorbed and fixed to the receiving disc by the connecting magnet, which can ensure the compression of the button and make the ejecting part more stable when it is located on the receiving disc.

[0030] Further, the receiving disc is rotatably connected with an annular rotating ring around the receiving part.

[0031] By adopting the above scheme, when the receiving part and the receiving disc rotate relative to each other, the friction between the connecting magnet and the receiving disc can be reduced.

[0032] In summary, the present application has at least the following advantages:

[0033] 1. By setting the bearing table replacement device at the conveying channel, without affecting the work of the feeding device, when the detector detects that there is material on the bearing table directly below, the control center controls the pushing mechanism to push the replacement part upward, in the process, the positioning block on the pushing rod is inserted into the positioning groove of the bearing table, and the bearing table is pushed upward. Then start the second pushing mechanism to drive the pushing rod to move to the tail end of the replacement part to the side of the frame body away from the installation frame, while the new bearing table is just located in the empty position in the conveying channel, at this time the second pushing mechanism is paused, the first pushing mechanism is started again, and the first pushing mechanism drives the replacement part to move downward. Make the new bearing table enter the empty position in the conveying channel and rest on the transmission roller, then the replacement part continues to move downward until the positioning block is out of the positioning groove, the first pushing mechanism is paused, and the bearing table replacement is completed, realizing the replacement of the unloaded bearing table in the conveying channel of the feeding device;

[0034] 2. By setting the receiving mechanism one at the tail end of the replacement part, after the first pushing mechanism pushes the replacement part upward to the highest position, the second driving mechanism drives the pushing rod to move in the direction of the tail end of the replacement part, the pushing part on the pushing rod carrying the bearing table gradually slides onto the receiving part, and when the pushing part completely leaves the sliding track, the pushing part forms abutment and pressing on the button in the receiving position. At this time, the control center drives the receiving disc to rotate by a fixed angle to make the next receiving part enter the receiving position, thereby continuously realizing the receiving of the pushing part and reducing the overall space occupation of the replacement mechanism;

[0035] 3. By setting the receiving mechanism two at the head end of the replacement mechanism, when the replacement part lifts the bearing table in the conveying channel to the highest position, the sliding track is aligned with the pushing part on the receiving part in the receiving position of the receiving mechanism two, the piston rod of the pushing part extends into the base part in the receiving position and contacts the driving part, then the piston rod of the pushing part continues to extend and drives the driving part to move towards the sliding track, sending the pushing part on the receiving part into the sliding track. And because the two receiving mechanisms are the same, they can be used alternately, that is, when the receiving mechanism at the tail end of the replacement part is full of bearing tables, the receiving mechanism at the head end of the replacement part is just released, at this time the two replacement positions can be exchanged.

[0051] Referring to Figure 2 and Figure 3 , specifically, the replacement mechanism comprises a mounting frame 4 supported on the ground, and a replacement part 5 arranged along the width direction of the conveying channel 11 is arranged on the mounting frame 4. The replacement part 5 comprises a sliding rail 51 and a push rod 52 slidingly connected in the sliding rail 51. A pushing mechanism I 41 is arranged between the sliding rail 51 and the mounting frame 4, and the pushing mechanism I 41 is used to drive the sliding rail 51 to move up and down in the vertical direction. In this case, the pushing mechanism I 41 is selected as a hydraulic cylinder or an air cylinder. A pushing mechanism II 512 is arranged between the push rod 52 and the sliding rail 51, and the pushing mechanism II 512 is used to realize the reciprocating movement of the push rod 52 in the sliding rail 51.

The driving assembly is too much in the prior art, and will not be described in detail in this case.

[0052] The upper surface of the push rod 52 is integrally provided with a plurality of positioning blocks 522, and the plurality of positioning blocks 522 are uniformly and spacedly arranged along the length direction of the push rod 52.

[0053] Referring to Figure 1 , the conveying channel 11 on both sides of the detector 31 is provided with a gap 13, the replacement part 5 penetrates through the gap 13, and the replacement part 5 is located between the adjacent two transmission rollers 5121. In order to facilitate subsequent description, one end of the replacement part 5 close to the mounting frame 4 is the leading end of the replacement part 5, and the other end of the replacement part 5 away from the mounting frame 4 is the trailing end of the replacement part 5.

[0054] Referring to Figure 4 The lower surface of the bearing table 2 is provided with a positioning groove 21 matched with the positioning block 522.

[0055] The first end of the replacement part 5 and the positioning block 522 on the push rod 52 are provided with a bearing table 2, which is arranged on the replacement part 5, and the positioning block 522 is inserted into the positioning groove 21 on the bearing table 2, and the positioning block 522 and the bearing table 2 are connected in sliding mode.

[0056] The feeding device operates in a progressive feeding mode, that is, the transmission roller 5121 drives a plurality of bearing tables 2 to move a distance in the conveying channel 11 and then pause. In the pausing process, the bearing tables 2 are operated by a mechanical hand or other equipment. Then the transmission roller 5121 drives the plurality of bearing tables 2 to continue to move and then pause. The feeding is realized in the above-mentioned mode. In this process, when the detector 31 detects that there is material on the bearing table 2 directly below, the control center controls the first pushing mechanism 41 to push the replacement part 5 to move upward. In the process, the positioning block 522 on the push rod 52 is inserted into the positioning groove 21 of the bearing table 2, and the bearing table 2 is pushed upward. Then the second pushing mechanism 512 is started to drive the push rod 52 to move to the tail end of the replacement part 5, and the bearing table 2 moves to the side away from the mounting frame 4 of the frame 1, and a new bearing table 2 is located in the empty position in the conveying channel 11. At this time, the second pushing mechanism 512 is paused, and the first pushing mechanism 41 is started again to pull the replacement part 5 to move downward. The new bearing table 2 enters the empty position in the conveying channel 11 and is arranged on the transmission roller 5121. Then the replacement part 5 continues to move downward until the positioning block 522 is separated from the positioning groove 21, and the first pushing mechanism 41 is paused. The bearing table 2 is replaced.

[0057] Referring to Figure 3 The sliding rail 51 includes a body 511, which is a rectangular channel steel. The inner wall of the body 511 is integrally provided with a connecting edge 5111 along the length direction. The outer wall of the push rod 52 is provided with a connecting groove 5213 matched with the connecting edge 5111. The connecting edge 5111 extends into the connecting groove 5213 and is connected with the push rod 52 in sliding mode. The above-mentioned structure can limit the vertical displacement of the push rod 52, so that the push rod 52 is more stable.

[0058] In the process of replacing the bearing table 2 in the conveying channel 11, in order to reduce the mutual interference between the detector 31 and the replacement part 5, the bracket 32 in the empty load detection device 3 is fixedly installed in the sliding rail 51 of the replacement part 5. In the process of upward movement of the replacement part 5, the empty load detector 31 is driven to move upward synchronously, so as to reduce the mutual interference between the detector 31 and the replacement part 5.

[0059] Referring to Figure 2Further, in order to reduce the space occupation, the pushing rod 52 is arranged by a plurality of pushing parts 521, and a plurality of positioning blocks 522 on the pushing rod 52 correspond to the plurality of pushing parts 521 one by one.

[0060] Referring to Figure 1 The tail end position of the replacement part 5 is provided with a storage mechanism for storing the pushing part 521 separated from the sliding rail 51. Specifically, the storage mechanism comprises a base 6 vertically arranged on the ground, and a storage disc 7 rotationally connected to the base 6, which is vertically arranged between the base 6 and the tail end of the replacement part 5. The base 6 is provided with a driving motor 61 for driving the storage disc 7 to rotate. One side of the storage disc 7 facing the replacement part 5 is provided with a plurality of storage parts 71, which are rod-shaped structures with rectangular cross sections and are vertically arranged on the storage disc 7. The plurality of storage parts 71 are arranged in a uniform circumferential array around the axis of the storage disc 7 on the storage disc 7. There is a position on the storage disc 7 such that the storage part 71 is aligned with the replacement part 5. In order to facilitate description, this position is named as a storage position 74.

[0061] The pushing part 521 is provided with a storage hole 22 matched with the storage part 71, and when the replacement part 5 lifts the carrying table 2 in the conveying channel 11 to the highest position, the storage part 71 in the storage position 74 is aligned with the storage hole 22.

[0062] Referring to Figure 5 And Figure 6 One side of the storage disc 7 is provided with a button 72 connected to the control center.

[0063] The pushing mechanism two 512 drives the pushing rod 52 in the direction of the tail end of the replacement part 5, and the pushing part 521 carrying the carrying table 2 on the pushing rod 52 gradually slides onto the storage part 71. When the pushing part 521 completely separates from the sliding rail 51, the pushing part 521 abuts and presses the button 72 in the storage position. At this time, the control center drives the storage disc 7 to rotate by a fixed angle through the driving motor 61, so that the next storage part 71 enters the storage position 74. Further, the storage of the pushing part 521 is continuously realized.

[0064] Referring to Figure 7 In order to ensure the stability of the material on the carrying table 2 in the storage mechanism during the rotation of the storage disc 7, the storage part 71 is a rectangular rod-shaped structure, and the storage hole 22 is matched with the storage part 71. When the carrying table 2 is located in the storage part 71, the carrying table 2 and the storage part 71 will not rotate relative to each other.

[0065] Referring to Figure 1 And Figure 7One end of the receiving member 71 is fixed with a connecting part 711 with a circular cross section, the connecting part 711 passes through the receiving disc 7, and the connecting part 711 is rotationally connected with the receiving disc 7. One end of the connecting part 711 passes through the receiving disc 7 and is fixed with a gravity part 714. Under the action of its own gravity, the gravity part 714 can prevent the carrier table 2 from rotating with the receiving disc 7.

[0066] The receiving mechanism is provided in two groups. For the convenience of description, the two groups of receiving mechanisms are respectively named as receiving mechanism one and receiving mechanism two. The receiving mechanism one is arranged at the tail end of the replacing member 5, and the receiving mechanism two is arranged at the head end of the replacing member 5.

[0067] One side of the receiving disc 7 of the receiving mechanism two, on which the receiving member 71 is located, faces the head end of the replacing member 5.

[0068] The receiving member 71 comprises a base part 712 and a driving part 713. The base part 712 is of a tubular structure with a rectangular cross section. The base part 712 is fixedly connected with the connecting part 711. A through hole 7111 is formed in the connecting part 711 in the axial direction and is in communication with the base part 712. A sliding groove 7131 adapted to the base part 712 is formed on the end surface of the driving part 713. The base part 712 extends into the sliding groove 7131 and is slidingly connected with the driving part 713.

[0069] Referring to Figure 8 The receiving mechanism further comprises a pushing member 8 arranged on the receiving disc 7 away from the replacing member 5. The pushing member 8 is selected from a hydraulic cylinder or an air cylinder. The pushing member 8 is fixedly installed to the base 6. The base part 712 of the receiving member 71 in the receiving position is coaxially arranged with the pushing member 8.

[0070] When the replacing member 5 lifts the carrier table 2 in the conveying channel 11 to the highest position, the sliding rail 51 is aligned with the pushing part on the receiving member 71 in the receiving position of the receiving mechanism two. The piston rod of the pushing member 8 extends into the base part 712 in the receiving part 74 and is in contact with the driving part 713. Then, the piston rod of the pushing member 8 continues to extend and pushes the driving part 713 to move towards the sliding rail 51, so as to send the receiving member 71 with the carrier table 2 to the sliding rail 51. Since the two receiving mechanisms are the same, they can be used alternately. That is, when the receiving mechanism one at the tail end of the replacing member 5 is fully loaded with the carrier table 2, the receiving mechanism two at the head end of the replacing member 5 is just released from the carrier table 2. At this time, the two receiving mechanisms can be replaced.

[0071] The end of the piston rod of the pushing member 8 is fixedly installed with an auxiliary magnet 81. The auxiliary magnet 81 is adsorbed to the driving part 713, so as to drive the driving part 713 to reset in the retraction process of the pushing member 8.

[0072] Referring to Figure 3The one end of the pushing part 521 is fixedly installed with a connecting magnet 5212, the connecting magnet 5212 can adsorb two adjacent pushing parts 521 together, and the continuity of the pushing rod 52 in the sliding rail 51 is ensured.

[0073] Further, the connecting magnet 5212 on the pushing part 521 in the sliding rail 51 is located at the one end towards the pushing mechanism. When the pushing part 521 is located on the storage part 71, the connecting magnet 5212 can be adsorbed and fixed to the storage disc 7, the button 72 can be pressed, and the pushing part 521 is more stable when located on the storage disc 7.

[0074] Referring to Figure 6 Further, the storage disc 7 on the periphery of the storage part 71 is rotationally connected with a rotating ring 73, and the rotating ring 73 is coaxially arranged with the storage part 71. The connecting magnet 5212 is adsorbed to the rotating ring 73. When the storage part 71 and the storage disc 7 relatively rotate, the friction between the connecting magnet 5212 and the storage disc 7 can be reduced.

[0075] The implementation principle of the present application is that the feeding device runs in a progressive feeding manner, that is, the transmission roller 5121 drives a plurality of bearing tables 2 to move a distance in the conveying channel 11 and then pause, in the process of pausing, other equipment such as a mechanical hand operates on the material on the bearing table 2, then the transmission roller 5121 drives the plurality of bearing tables 2 to continue to move and then pause, and feeding is realized in the above-mentioned manner. In this process, when the detector 31 detects that there is material on the bearing table 2 directly below, the control center controls the pushing mechanism to move upward, in the process, the positioning block 522 on the pushing rod 52 is inserted into the positioning groove 21 of the bearing table 2, and the bearing table 2 is pushed upward. Then the pushing mechanism two 512 drives the pushing rod 52 to move to the tail end of the replacement part 5, the pushing part 521 of the pushing rod 52 carrying the bearing table 2 gradually slides onto the storage part 71, and when the pushing part 521 completely separates from the sliding rail 51, the pushing part 521 abuts and presses the button 72 in the storage position. At this time, the control center drives the storage disc 7 to rotate by a fixed angle through the driving motor 61, so that the next storage part 71 enters the storage position. At the same time, the new bearing table 2 is located in the vacant position in the conveying channel 11, at this time the pushing mechanism two 512 pauses, and the pushing mechanism one 41 starts again. The pushing mechanism one 41 drives the replacement part 5 to move downward. The new bearing table 2 enters the empty position in the conveying channel 11 and is erected to the transmission roller 5121, then the replacement part 5 continues to move downward until the positioning block 522 separates from the positioning groove 21, and the pushing mechanism one 41 pauses, and the bearing table 2 is replaced. In this process, when the replacement part 5 lifts the bearing table 2 in the conveying channel 11 to the highest position, the sliding rail 51 is aligned with the pushing part in the storage position in the storage mechanism two, the piston rod of the pushing part 8 extends into the base part 712 in the storage position and contacts the driving part 713, then the piston rod of the pushing part 8 continues to extend and drives the driving part 713 to move toward the sliding rail 51, and the bearing table 2 on the pushing part 521 of the storage part 71 is sent into the sliding rail 51, and the pushing part 521 in the sliding rail 51 is attracted by the connecting magnet 5212.

[0076] The embodiments of the specific embodiment are the preferred embodiments of the present application, but do not limit the protection scope of the present application, wherein the same parts are indicated by the same reference numerals. Therefore, any effective change made according to the structure, shape and principle of the present application should be covered in the protection scope of the present application.
