Description

Technical Field

[0001] The present invention relates to the technical field of air conditioner processing, and in particular to a feeding device and a feeding equipment having the same. Background Art

[0002] At present, in the production process of air-conditioning evaporators and condensers, a small U-shaped elbow needs to be inserted into the copper tubes of the evaporator and the condenser at the same time. A welding ring is provided on each of the two copper tubes of the small U-shaped elbow. After the small U-shaped elbow is inserted into the condenser and the evaporator, the condenser and evaporator that have been preliminarily processed will be transported to the welding station to melt the welding ring, and then the small U-shaped elbow, the copper tube of the evaporator and the copper tube of the condenser will be welded together to ensure the airtightness of the connection between the two.

[0003] In the prior art, for the above processing steps, the entire feeding process of the small U-shaped elbow is actually carried out in the form of vibration feeding, that is, the vibration action of the vibration plate is required to complete the transportation of the small U-shaped elbow from the feed tray to the distribution tray.

[0004] However, the vibration feeding method has the following two problems:

[0005] 1. The feeding rhythm is poorly uniform, that is, during the vibration feeding process, the small U-shaped elbow needs to move gradually by the vibration action, and its moving speed, that is, the time required to transport from the feed tray to the distribution tray, cannot be accurately controlled. Especially when the small U-shaped elbow needs to be transported over a long distance due to the layout of the processing production line, the small U-shaped elbow is prone to jamming, and the feeding time will produce a greater error. At this time, the subsequent production equipment can only continue to operate after the small U-shaped elbow is loaded, affecting the overall processing efficiency of the production line;

[0006] 2. The accuracy of the feeding position is poor, that is, the feeding position of the vibration feeding cannot be accurately controlled. It can only rely on the sensor to detect whether the corresponding size of the small U-shaped elbow at the preset position reaches the preset size to determine whether the current small U-shaped elbow is loaded in place. However, if there is a processing error in the small U-shaped elbow, it will cause the sensor to misjudge. At this time, if the dividing plate performs corresponding actions, it will cause damage to the small U-shaped elbow and even damage the structure of the dividing plate itself. Summary of the invention

[0007] The main purpose of the present invention is to provide a feeding device and a feeding equipment having the same, so as to solve the problems of poor feeding rhythm uniformity and poor feeding position accuracy of a small U-shaped elbow of an air conditioner in the prior art.

[0008] In order to achieve the above-mentioned purpose, according to one aspect of the present invention, there is provided a feeding device, which is arranged on the feeding equipment and is located between the feeding device and the dividing device, so as to transport the material on the feeding device to the dividing device, and the feeding device comprises: a material channel structure, which has a feeding channel for accommodating the material; a feeding component, which is movably arranged along the extension direction of the feeding channel, and the feeding component comprises a feeding structure with a limiting recess; wherein the feeding structure can be raised and lowered and has a feeding position and an avoidance position, when the feeding structure is in the feeding position, the limiting recess at least partially limits the material in the extension direction of the feeding channel, and the feeding component drives the material to move through the limiting stop between the limiting recess and the material to feed the material; when the feeding structure moves to the avoidance position, the feeding structure avoids the material in the extension direction of the feeding channel.

[0009] Furthermore, the material channel structure includes: a material channel body, having a first material channel and a mounting notch connected to the first material channel; a loading piece, having a second material channel; wherein the loading piece can be movably arranged at the mounting notch and has a loading position and a receiving position, and when the loading piece is in the receiving position, the second material channel is connected to the discharge port of the feeding device to receive the material discharged through the feeding device; when the loading piece moves to the loading position, the second material channel is connected to the first material channel to form a feeding channel.

[0010] Furthermore, there are multiple limiting recesses, which are arranged at intervals along the extension direction of the feeding channel; wherein, when the feeding structure is in the feeding position, at least one limiting recess and the material limiting stop located in the second material channel are used to take the material in the second material channel when the feeding component drives the material to move.

[0011] Furthermore, a notch penetrating the feeding structure is provided on the feeding structure, and an inner wall of the notch forms a limiting recess; wherein the shape of the limiting recess matches the shape of at least a portion of the outer peripheral surface of the material.

[0012] Furthermore, the feeding structure is plate-shaped, and the extension direction of the feeding structure is consistent with the extension direction of the feeding channel. The multiple limiting recesses include multiple feeding recesses and discharging recesses. The discharging recesses are arranged close to the dividing device relative to the feeding recesses, and the discharging recesses extend to the side of the feeding structure close to the dividing device to form a discharging opening on the side.

[0013] Furthermore, the depth of the feeding channel is greater than or equal to the height of the material; the feeding structure is plate-shaped, and the extension direction of the feeding structure is consistent with the extension direction of the feeding channel; wherein, the feeding structure between two adjacent limiting recesses forms an insertion portion, and when the feeding structure is in the feeding position, at least part of the insertion portion is inserted into the feeding channel.

[0014] Furthermore, the feeding assembly also includes a first driving member, which is drivably connected to the feeding structure to drive the feeding structure to move up and down; the feeding device also includes a second driving member, which is drivably connected to the first driving member to drive the first driving member to drive the feeding structure to move along the extension direction of the feeding channel.

[0015] Furthermore, at least a portion of the outer surface of the loading piece forms a blocking surface, and when the loading piece moves to the loading position, the blocking surface blocks the discharge port of the feeding device; and / or, the feeding device also includes a third driving member, which is drivingly connected to the loading piece, and the third driving member is used to drive the loading piece to move between the loading position and the receiving position; and / or, the feeding device also includes a blocking member, which is located on a side of the loading piece away from the feeding device, and when the loading piece is in the receiving position, the blocking member blocks an end of the second material channel away from the feeding device.

[0016] Furthermore, the material channel body includes: a bottom plate; a side plate, which is arranged on the bottom plate, and there are at least two side plates, which are arranged opposite to each other to surround and form a first material channel; wherein, each side plate is provided with a mounting recess that penetrates the side plate on the side away from the bottom plate, so as to form a mounting gap around the inner walls of the at least two mounting recesses and the upper surface of the bottom plate.

[0018] According to the technical solution of the present invention, a feeding device is arranged on a feeding equipment and is located between a feeding device and a dividing device, so as to transport materials on the feeding device to the dividing device. A material channel structure of the feeding device has a feeding channel for accommodating materials. A feeding component is movably arranged along an extension direction of the feeding channel.

The feeding component drives the material to move through the limiting stop between the limiting recess and the material to perform feeding. When the feeding structure moves to the avoidance position, the feeding structure avoids the material in the extension direction of the feeding channel. In this way, for the material transportation between the feeding device and the distributing device, the present application completely eliminates the traditional vibration transportation method, that is, when the feeding structure moves to the feeding position, the feeding assembly can push the material located in the feeding channel to the corresponding loading position at one time through the limiting concave part of the feeding structure and the limiting stop between the material, which has a high loading position accuracy. At the same time, when the feeding structure moves to the avoidance position, the feeding assembly can perform a reset movement without interfering with the material. Through the mutual cooperation between the feeding assembly (whole) and the feeding structure (part), the uninterrupted transportation of the material (similar to step-by-step transportation) can be achieved, and the staff only needs to adjust the movement speed of the feeding assembly and the feeding structure to obtain a stable feeding beat, thereby solving the problem of poor feeding beat uniformity and feeding position accuracy of the small U-shaped elbow of the air conditioner in the prior art.

The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0038] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meanings as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0039] In the present invention, unless otherwise specified, the directional words used, such as "up" and "down", usually refer to the directions shown in the drawings, or to the vertical, perpendicular or gravity directions; similarly, for ease of understanding and description, "left" and "right" usually refer to the left and right shown in the drawings; "inside" and "outside" refer to the inside and outside relative to the outline of each component itself, but the above directional words are not used to limit the present invention.

[0040] In order to solve the problem of poor uniformity of feeding rhythm and poor accuracy of feeding position of small U-shaped elbow of air conditioner in the prior art, the present application provides a feeding device and a feeding equipment having the same.

[0041] like Figures 1 to 7 As shown, the feeding device is arranged on the feeding equipment and is located between the feeding device 1 and the dividing device 2, so as to transport the material 3 on the feeding device 1 to the dividing device 2, and the feeding device includes: a material channel structure 10, having a feeding channel 11 for accommodating the material 3; a feeding component 20, which is movably arranged along the extension direction of the feeding channel 11, and the feeding component 20 includes a feeding structure 21 with a limiting recess 211; wherein the feeding structure 21 can be raised and lowered and has a feeding position and an avoidance position, when the feeding structure 21 is in the feeding position, the limiting recess 211 is at least partially limited to the material 3 in the extension direction of the feeding channel 11, and the feeding component 20 drives the material 3 to move through the limiting stop between the limiting recess 211 and the material 3 to feed; when the feeding structure 21 moves to the avoidance position, the feeding structure 21 avoids the material 3 in the extension direction of the feeding channel 11.

[0042] The technical solution of this embodiment is applied, the feeding device is arranged on the feeding equipment and is located between the feeding device 1 and the dividing device 2, so as to transport the material 3 on the feeding device 1 to the dividing device 2, the material channel structure 10 of the feeding device has a feeding channel 11 for accommodating the material 3, the feeding assembly 20 is movably arranged along the extension direction of the feeding channel 11, and the feeding assembly 20 includes a feeding structure 21 having a limiting recess 211. Among them, the feeding structure 21 can be raised and lowered and has a feeding position and an avoidance position. When the feeding structure 21 is in the feeding position, the limiting recess 211 is at least partially limited to the material 3 in the extension direction of the feeding channel 11. The feeding assembly 20 drives the material 3 to move through the limiting recess 211 and the material 3 to feed; when the feeding structure 21 moves to the avoidance position, the feeding structure 21 avoids the material 3 in the extension direction of the feeding channel 11. In this way, for the material transportation between the feeding device 1 and the distributing device 2, the present embodiment completely eliminates the traditional vibration transportation mode, that is, when the feeding structure 21 moves to the feeding position, the feeding assembly 20 can push the material 3 located in the feeding channel 11 to the corresponding loading position at one time through the limit stop between the limit recess 211 of the feeding structure 21 and the material 3, which has a high loading position accuracy. At the same time, when the feeding structure moves to the avoidance position, the feeding assembly 20 can perform a reset movement without interfering with the material 3. Through the mutual cooperation between the feeding assembly 20 (whole) and the feeding structure 21 (part), the uninterrupted transportation of the material 3 (similar to step-by-step transportation) can be achieved, and the staff only needs to adjust the movement speed of the feeding assembly 20 and the feeding structure 21 to obtain a stable feeding beat, thereby solving the problem of poor loading beat uniformity and loading position accuracy of the small U-shaped elbow of the air conditioner in the prior art.

[0043] In this embodiment, the feeding device is arranged as a whole on the frame of the loading equipment. The staff can also set up a separate frame for the feeding device according to actual needs to realize the modular design of the feeding device, thereby facilitating the connection between the feeding device and other processing devices in the automated production line to improve the versatility of the feeding device.

[0044] In this embodiment, material 3 is a small U-shaped elbow used in the process of connecting two devices (evaporator and condenser) of the air conditioner.

[0045] like Figures 3 to 7 As shown, in order to facilitate observation of the matching state between the feeding structure 21 and the material 3, Figure 3 A portion of the channel structure 10 (the side plate 124 of the channel body 12) is disassembled to expose the material 3 in the feeding channel 11. Figures 4 to 7 The feeding process of the feeding component 20 is shown in sequence. Figure 4That is, the feeding assembly 20 moves to the initial position as a whole, and the feeding structure 21 rises to the avoidance position. Figure 5 The feeding structure 21 in the middle descends to the feeding position, and the material 3 enters into the limiting recess 211 and is stopped by the inner wall of the limiting recess 211. Figure 6 The feeding assembly 20 moves as a whole to drive the material 3 to move, and then transport the material 3 to the loading position. Figure 7 The feeding structure 21 in the middle rises to the avoidance position again, and the feeding assembly 20 is ready to move to Figure 5 At the position of Figures 5 to 7 The feeding process is realized, thereby realizing the repetitive transportation of material 3.

[0046] like Figures 1 to 3 As shown, the material channel structure 10 includes: a material channel body 12, having a first material channel 121 and a mounting notch 122 connected to the first material channel 121; a feeding piece 13, having a second material channel 131; wherein the feeding piece 13 is movably arranged at the mounting notch 122 and has a feeding position and a receiving position, when the feeding piece 13 is at the receiving position, the second material channel 131 is connected to the discharge port 101 of the feeding device 1, so as to receive the material 3 discharged through the feeding device 1; when the feeding piece 13 moves to the feeding position, the second material channel 131 is connected to the first material channel 121 to form a feeding channel 11. In this way, the setting of the feeding piece 13 can realize the fixed amount of material feeding between the feeding device 1 and the feeding device (material channel structure 10), so as to prevent the material 3 from accumulating in the feeding channel 11 due to excessive amount of material 3 transported, thereby improving the feeding stability of the feeding device.

[0047] Specifically, when the loading piece 13 is in the material receiving position, the second material channel 131 is connected with the discharge port 101 of the feeding device 1 to receive the material 3 discharged through the feeding device 1, and when the loading piece 13 moves to the loading position, the second material channel 131 is connected with the first material channel 121 to form a feeding channel 11, that is, the material 3 is loaded into the material channel structure 10 at this time.

[0048] like Figure 1 As shown, the loading member 13 is now in the loading position, and its second material channel 131 and the first material channel 121 of the material channel body 12 are connected to each other to form a connected feeding channel 11 and complete the loading.

[0049] like Figure 3 As shown, the loading member 13 is now in the material receiving position, and its second material channel 131 is connected to the discharge port 101 of the feeding device 1 to receive the material 3 discharged through the discharge port 101 .

[0050] Optionally, there are multiple limiting recesses 211, and the multiple limiting recesses 211 are arranged at intervals along the extension direction of the feeding channel 11. Among them, when the feeding structure 21 is in the feeding position, at least one limiting recess 211 and the material 3 located in the second material channel 131 are limited and stopped, so that the material 3 in the second material channel 131 can be taken out when the feeding component 20 drives the material 3 to move. In this way, the above arrangement ensures that when the feeding component 20 drives the material 3 in the feeding channel 11 to move through the feeding structure 21 to transport the material, the feeding structure 21 can drive the material 3 located in the second material channel 131 to move, that is, it can take out the material 3 newly loaded into the material channel structure 10.

[0051] In this embodiment, there are eight limiting recesses 211 , and the eight limiting recesses 211 are arranged at intervals along the extension direction of the feeding channel 11 to synchronously convey the eight materials 3 in the feeding channel 11 .

[0052] It should be noted that the number of the limiting recesses 211 is not limited thereto, and can be adjusted according to working conditions and usage requirements. Optionally, the number of the limiting recesses 211 is two, three, four, five, six, or more.

[0053] like Figure 1 and Figure 3 As shown, the feeding structure 21 is provided with a notch penetrating the feeding structure 21, and the inner wall of the notch forms a limiting recess 211. The shape of the limiting recess 211 matches the shape of at least part of the outer peripheral surface of the material 3. Thus, the above arrangement makes the formation of the limiting recess 211 simpler on the one hand; on the other hand, it can increase the matching area between the inner wall of the limiting recess 211 and the material 3, so as to improve the matching reliability between the two.

[0054] In this embodiment, the limiting recess 211 is a semicircular recess, and its semicircular inner wall matches the arc-shaped outer surface of the small U-shaped elbow.

[0055] like Figure 1 and Figure 3As shown, the feeding structure 21 is plate-shaped, and the extension direction of the feeding structure 21 is consistent with the extension direction of the feeding channel 11. The multiple limiting recesses 211 include multiple feeding recesses 212 and discharge recesses 213. The discharge recesses 213 are arranged close to the material distribution device 2 relative to the feeding recesses 212, and the discharge recesses 213 extend to the side of the feeding structure 21 close to the material distribution device 2 to form a discharge opening 214 on the side. In this way, during the movement and feeding process of the feeding assembly 20, the material located in the discharge recess 213 will move into the material distribution device 2. The discharge opening 214 can avoid mutual interference between the feeding structure 21 and the material distribution device 2 on the one hand; on the other hand, it can ensure that the material 3 enters the material distribution device 2 quickly and reliably, thereby improving the feeding stability of the feeding structure 21.

[0056] In this embodiment, the feeding structure 21 is generally plate-shaped and is located on the side of the feeding channel 11. It is vertically arranged and the extension direction of the plate-shaped structure is consistent with the extension direction of the feeding channel 11. The feeding structure 21 has a notch extending to its lower surface, and the notch stroke limit recess 211. Among the multiple limit recesses 211, the limit recess 211 arranged close to the dividing device 2 is the feeding recess 212. The feeding recess 212 extends to the lower surface of the feeding structure 21 and the surface close to the dividing device 2 at the same time to form a discharge opening 214 on the side of the feeding structure 21 close to the dividing device 2. The feeding recess 212 can be connected with the dividing device 2 through the discharge opening 214, so that the material 3 located in the feeding recess 212 can move directly into the dividing device 2.

[0057] like Figure 1 , Figure 3 and Figure 5 As shown, the depth of the feeding channel 11 is greater than or equal to the height of the material 3; the feeding structure 21 is plate-shaped, and the extension direction of the feeding structure 21 is consistent with the extension direction of the feeding channel 11; wherein, the feeding structure 21 between two adjacent limiting recesses 211 forms an insertion portion 215, and when the feeding structure 21 is in the feeding position, at least part of the insertion portion 215 is inserted into the feeding channel 11. In this way, the above-mentioned arrangement enables the feeding channel 11 to fully accommodate the material 3 on the one hand, so as to improve its reliability of accommodating the material 3; on the other hand, the arrangement of the insertion portion 215 enables the feeding structure 21 to partially extend into the feeding channel 11, further increasing the matching area between the feeding structure 21 and the material 3. At the same time, when the material 3 located in the feeding channel 11 is stuck with the inner wall of the feeding channel 11, the insertion portion 215 can also promptly push the material 3 to move, so as to further improve the smoothness of the movement of the material 3.

[0058] like Figure 1 and Figure 3As shown, the feeding assembly 20 further includes a first driving member 22, which is drivingly connected to the feeding structure 21, so as to drive the feeding structure 21 to move up and down; the feeding device further includes a second driving member 30, which is drivingly connected to the first driving member 22, so as to drive the first driving member 22 to drive the feeding structure 21 to move along the extension direction of the feeding channel 11. In this way, the above arrangement realizes the automatic movement of the feeding structure 21 through the first driving member 22 on the one hand, and realizes the automatic movement of the feeding assembly 20 through the second driving member 30 on the other hand.

[0059] Optionally, the first driving member 22 is a driving cylinder (such as a pneumatic cylinder), and the second driving member 30 is a driving cylinder (such as a pneumatic cylinder).

[0060] Specifically, the drive cylinder has a better response speed and a more precise movement stroke, which helps to improve the uniformity of the feeding beat and the accuracy of the feeding position of the material 3. At the same time, the staff can also adjust the feeding beat (i.e., the time used to complete the entire feeding process of a material 3) by controlling the driving speed of the drive cylinder to match the subsequent processing requirements.

[0061] like Fig.10 As shown, at least part of the outer surface of the feeding member 13 forms a blocking surface 132, and when the feeding member 13 moves to the feeding position, the blocking surface 132 blocks the discharge port 101 of the feeding device 1. In this way, when the feeding member 13 moves to the feeding position to feed the material 3, its outer surface (blocking surface 132) can also block the discharge port 101 of the feeding device 1 to prevent the material 3 from falling.

[0062] In this embodiment, the loading piece 13 is a block-shaped structure as a whole, and a groove is processed on the loading piece 13 to form the second material channel 131 through the groove.

[0063] Specifically, a bell mouth is processed on one end of the second material channel 131 close to the feeding device 1 , and the setting of the bell mouth can reduce the difficulty of the material 3 discharged through the discharge port 101 entering the second material channel 131 .

[0064] like Figure 1 and Figure 3As shown, the feeding device further includes: a third driving member 40, which is drivingly connected to the loading member 13, and the third driving member 40 is used to drive the loading member 13 to move between the loading position and the receiving position; and / or a blocking member 50, which is located on the side of the loading member 13 away from the feeding device 1, and when the loading member 13 is in the receiving position, the blocking member 50 blocks the end of the second material channel 131 away from the feeding device 1. In this way, the above arrangement realizes the automatic movement of the loading member 13 through the third driving member 40 on the one hand; the setting of the blocking member 50 can block the end of the second material channel 131 away from the feeding device 1 when the loading member 13 is in the receiving position, so as to prevent the material entering the second material channel 131 from continuing to move under the action of inertia and causing it to fall.

[0065] In this embodiment, the blocking member 50 is in a block shape.

[0066] like Figure 1 , Figure 3 and Figure 4 As shown, the material channel body 12 includes: a bottom plate 123; a side plate 124, which is arranged on the bottom plate 123, and there are at least two side plates 124, which are arranged opposite to each other to surround and form a first material channel 121; wherein, each side plate 124 is provided with a mounting recess 125 penetrating the side plate 124 on the side away from the bottom plate 123, so as to surround and form a mounting gap 122 between the inner walls of at least two mounting recesses 125 and the upper surface of the bottom plate 123. In this way, the above arrangement makes the structure of the material channel body 12 and the formation method of the mounting gap 122 simpler, easier to process and realize, and also reduces the processing cost of the material channel body 12 and the processing difficulty of the staff.

[0067] In this embodiment, there are two side plates 124 , which are disposed on the bottom plate 123 and opposite to each other, so that the first material channel 121 is formed by the plate surfaces of the two side plates 124 facing each other and the bottom plate 123 .

[0068] In this embodiment, an expanded diameter end 1211 (bell mouth) is provided at the end of the first material channel 121 located on the side of the installation notch 122 away from the loading piece 13 and close to the loading piece 13, so as to reduce the difficulty of the material 3 entering from the second material channel 131 into the first material channel 121, avoid the material 3 from getting stuck, and ensure that the material 3 can be smoothly transported.

[0069] like Figures 8 to 10 As shown, this embodiment also provides a loading device, which includes a feeding device 1, a feeding device and a dividing device 2. The feeding device is located between the feeding device 1 and the dividing device 2. The feeding device is used to transport the material 3 transported to the feeding device via the feeding device 1 to the dividing device 2. Among them, the feeding device is the above-mentioned feeding device.

[0070] In this embodiment, the feeding device 1 is a vibrating feeding tray, and its structure is relatively conventional and will not be described in detail here.

[0071] In the present embodiment, the material distribution device 2 includes a material distribution plate 201 and a driving structure 203, the driving structure 203 is used to drive the material distribution plate 201 to rotate, a plurality of material troughs 202 are arranged on the material distribution plate 201, one end of the material trough 202 extends to the outer peripheral surface of the material distribution plate 201 to form a feed port, and a limiting member 204 is also arranged on the material distribution plate 201 at the material trough 202, and the limiting member 204 includes two limiting structures arranged relatively to each other, and the two limiting structures are arranged relatively to form a limiting space around, and during the feeding process of the feeding component 20 of the feeding device, the feeding structure 21 actually feeds the material 3 into the material trough 202 That is, the material distribution plate 201 will rotate to the feed port of the material trough 202 and be arranged opposite to the end of the feeding channel 11. When the feeding structure 21 moves to the corresponding position, the material 3 in its feeding recess 212 moves into the material trough 202 through the feed port. After the material enters the material trough 202, it will move into the limit space to maintain its posture through the limit member 204. When the material trough 202 is loaded, the feeding structure 21 rises to the avoidance position, the feeding assembly 20 is reset, and the material distribution plate 201 rotates to the feed port of the next material trough 202 and is opposite to the end of the feeding channel 11 to load the next material trough 202.

[0072] Specifically, in the traditional vibration feeding process, it is impossible to accurately control whether the material 3 has moved into the material trough 202. It is only possible to set a sensor on the distribution plate 201, such as a distance sensor, to detect the distance between the material 3 and the detection end. When the distance reaches a preset value, it is judged that the material 3 has entered the material trough 202. If the material 3 has a processing error or is itself an unqualified part, the detection result of the distance sensor will be invalid. At this time, it is easy for the material 3 to not completely enter the material trough 202, and the distribution plate 201 will start to rotate. The material 3 will be stuck in the rotation of the distribution plate 201, and even cause damage to the distribution device 2. However, the feeding device in this embodiment can completely avoid the occurrence of the above-mentioned problem, that is, when the control module controls the first drive member 22 and the second drive member 30 to move into place, it can ensure that the material 3 is loaded in place, and then the rotation of the distribution plate 201 is controlled. There is no need to set a sensor, thereby reducing the processing cost of the distribution device 2.

[0073] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0074] The feeding device is arranged on the feeding equipment and is located between the feeding device and the dividing device, so as to transport the material on the feeding device to the dividing device. The material channel structure of the feeding device has a feeding channel for accommodating the material. The feeding component is movably arranged along the extension direction of the feeding channel. The feeding component includes a feeding structure with a limiting recess, wherein the feeding structure can be raised and lowered and has a feeding position and an avoidance position. When the feeding structure is in the feeding position, the limiting recess at least partially limits the material in the extension direction of the feeding channel. The feeding component drives the material to move through the limiting stop between the limiting recess and the material to feed the material; when the feeding structure moves to the avoidance position, the feeding structure avoids the material in the extension direction of the feeding channel. In this way, for the material transportation between the feeding device and the distributing device, the present application completely eliminates the traditional vibration transportation method, that is, when the feeding structure moves to the feeding position, the feeding assembly can push the material located in the feeding channel to the corresponding loading position at one time through the limiting concave part of the feeding structure and the limiting stop between the material, which has a high loading position accuracy. At the same time, when the feeding structure moves to the avoidance position, the feeding assembly can perform a reset movement without interfering with the material. Through the mutual cooperation between the feeding assembly (whole) and the feeding structure (part), the uninterrupted transportation of the material (similar to step-by-step transportation) can be achieved, and the staff only needs to adjust the movement speed of the feeding assembly and the feeding structure to obtain a stable feeding beat, thereby solving the problem of poor feeding beat uniformity and feeding position accuracy of the small U-shaped elbow of the air conditioner in the prior art.
