Description

Technical Field

[0001] This invention relates to the field of aluminum cantilever arms for overhead contact lines, and more specifically to a single-ear assembly device for aluminum cantilever arm production. Background Technology

[0002] With the rapid development of railway construction in my country, new requirements have been placed on the process quality standards of related components in the railway industry, and the precision requirements for the construction and maintenance of railway lines are becoming increasingly stringent. In railway lines, the overhead contact system is a crucial component ensuring normal railway operation. Connected to the electrified railway power supply lines, it directly undertakes the primary task of supplying energy to electric trains. The cantilever arm is the support device for the overhead contact system, and its pre-assembly is an important aspect of electrified railway construction. High-speed railways have extremely high precision requirements for overhead contact system installation, and most components of high-speed railway overhead contact system projects cannot be repeatedly disassembled and reassembled. After accurate calculations, the cantilever arm support device must be precisely assembled in one go. Due to constraints such as high-altitude conditions on site, a pre-fabrication method based on ground batches is necessary. The quality of this one-time construction in the entire contact suspension directly affects the quality, progress, and efficiency of subsequent construction. The cantilever arm includes the cantilever tube and the sleeve seat, load-bearing cable seat, and single ear fixed to the cantilever tube. The result of the single ear is as follows... Figure 6 As shown, the single ear includes a single ear platform portion b61, a single ear collar b62, and a single ear connecting portion b63. ​​The two ends of the single ear collar b62 extend beyond the bottom surfaces of both ends of the single ear platform portion b61 and are secured with nuts. The outer surface of the single ear connecting portion b63 is an arc surface and is longitudinally located at the lower end of the single ear platform portion b61. Currently, in the automated production of carousels, when installing the single ear onto the carousel tube, continuous material replenishment of the single ear is required to adapt to the automated production process. Due to the special structure of the single ear, storage is difficult, and currently there is no suitable method for its storage. Figure 13 The continuous conveying device for the single ear requires manual replenishment, which increases labor costs and reduces replenishment efficiency during the cantilever arm production process. Furthermore, the installation direction of the single ear on the cantilever arm tube is critical; some bolts face upwards, while others downwards. The tightening module can only tighten downward-facing bolts. During assembly with the cantilever arm tube, the tube must be continuously rotated to ensure the single ear, sleeve seat, or load-bearing cable seat all meet the required orientation. Current technology often involves manually fitting the single ear onto the cantilever arm tube, adjusting its position, and then tightening it, resulting in low assembly efficiency.

Detailed Implementation

[0044] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0045] Example 1:

[0046] An improved single-ear assembly device for aluminum cantilever arm production includes a single pre-rail module a1 and a single-ear pickup module a8. A single-ear conveying device b is located to the right rear of the single pre-rail module a1. A single pre-feeding tube module a6 is mounted on the single pre-rail module a1. Multiple single pre-support clamping modules a7 are located to the side of the single pre-rail module a1, to the left of the single pre-feeding tube module a6. Multiple single pre-support frame modules a2 are located to the left of the single pre-support clamping module a7, and the multiple single pre-support frame modules a2 and the multiple single pre-support clamping modules a7 are aligned on the same straight line. A single pre-tightening module a4 is located on the single pre-rail module a1 and to the left of the single pre-feeding tube module a6. The single pre-rail module a1 also has a single... The pre-stretched tube module a3; the single-ear conveying device b is used to continuously supply single-ear b6 to the aluminum cantilever production line; the single-ear picking module a8 is used to grab single-ear b6 from the single-ear conveying device b and transfer it between adjacent single pre-support pressing modules a7; the single pre-feeding tube module a6 is used to clamp the cantilever tube and continue to convey it to the left so that the cantilever tube passes through the single-ear b6; the single pre-support pressing module a7 is used to support and press the cantilever tube conveyed by the single pre-feeding tube module a6; the single pre-tightening module a4 is used to move below the single-ear b6 and lock the single-ear and cantilever tube; the single pre-stretched tube module a3 is used to clamp the cantilever tube conveyed by the single pre-feeding tube module a6 and continue to convey it to the left; the single pre-support frame module a2 is used to support the cantilever tube conveyed by the single pre-stretched tube module a3.

[0047] In this embodiment, the single ear pickup module a8 is used to grab the single ear b6 and transfer it between the adjacent single pre-support and clamping modules a7. The single pre-feeding tube module a6 is used to clamp the carpal tube and continue to feed it to the left so that the carpal tube passes through the single ear. The single pre-support and clamping module a7 is used to support and clamp the carpal tube fed by the single pre-feeding tube module a6. The single pre-tightening module a4 is used to move to the bottom of the single ear b6 and lock the single ear b6 and the carpal tube. The single pre-pull tube module a3 is used to clamp the carpal tube fed by the single pre-feeding tube module a6 and continue to feed it to the left. The single pre-support frame module a2 is used to support the carpal tube fed by the single pre-pull tube module a3.

[0048] In this embodiment, the specific operation is as follows: First, the single-ear conveyor b continuously supplies single-ear b6 to the aluminum cantilever production line. The single-ear pickup module a8 picks up the single-ear b6 from the single-ear conveyor b and transfers it between two adjacent single pre-support clamping modules a7. Preferably, the single-ear pickup module a8 transfers the single-ear b6 between the two single pre-support clamping modules a7 closest to the single pre-support frame module a2. Then, the single pre-feeding tube module a6 clamps the cantilever tube conveyed from the previous station and continues to convey it to the left so that the cantilever tube passes through the single-ear b6. When the cantilever tube is long enough, it can also directly pass through the single-ear b6 under the conveying of the previous station. In this case, the single pre-feeding tube module a6 only serves to clamp the cantilever tube and continue to convey it to the left. Then, the single pre-pulling tube module a3 clamps the conveyed cantilever tube and continues to convey it to the left. During the transport of the carpal tube, when the carpal tube reaches the position of the pre-fitted single ear b6, the transport is paused, the single pre-support clamping module a7 clamps the carpal tube, the single pre-tightening module a4 moves below the single ear b6 to lock the single ear b6 and the carpal tube, and then the carpal tube continues to be transported.

[0049] Compared with existing technologies, this embodiment achieves automated assembly of single ears of aluminum cantilever arms by setting up modules such as single ear conveying device b, single pre-tensioning tube module a3, single pre-tightening module a4, single pre-feeding tube module a6, and single pre-supporting and pressing module a7. The single ear conveying device b ensures a continuous supply of single ears in the production line. The single pre-tensioning tube module a3 and the single pre-feeding tube module a6 ensure the accuracy of the assembly position of the single ear and the cantilever tube. The single pre-tightening module a4 and the single pre-supporting and pressing module a7 ensure that the locking force of the single ear is uniform, thereby improving work efficiency and product qualification rate.

[0050] Furthermore, refer to Figure 5 As shown, the single pre-feed tube module a6 includes a single pre-feed tube base a61 disposed on the single pre-rail module a1, a single pre-feed tube movement driver a63 disposed on the single pre-feed tube base a61 and driving the single pre-feed tube base a61 to move relative to the single pre-rail module a1, and a single pre-feed tube support a62 disposed on the single pre-feed tube base a61. The single pre-feed tube support a62 is provided with a single pre-feed tube clamping driver a64. The telescopic end of the single pre-feed tube clamping driver a64 is connected to a single pre-feed tube gripper a65. The single pre-feed tube gripper a65 is used to clamp the wrist arm tube.

[0051] Furthermore, refer to Figure 2As shown, the single pre-support frame module a2 includes a single pre-support column a21 and a single pre-support lifting cylinder a22 disposed on the single pre-support column a21. The telescopic end of the single pre-support lifting cylinder a22 is provided with a single pre-support connecting plate a23, and the single pre-support connecting plate a23 is provided with a single pre-support roller a24. The single pre-support roller a24 is used to support the carpenter arm tube.

[0052] In this embodiment, the single pre-support lifting cylinder a22 and the single pre-support connecting plate a23 are designed to avoid interference between the single pre-support frame module a2 and the single pre-tensioning pipe module a3 during the transport of the cantilever tube.

[0053] Example 2:

[0054] Based on Example 1, referring to Figure 6 As shown, the single pre-support clamping module a7 includes a single pre-support clamping column a71, a single pre-support clamping lifting driver a72 disposed on the single pre-support clamping column a71, a single pre-support clamping connecting plate a74 disposed on the telescopic end of the single pre-support clamping lifting driver a72, a single pre-support clamping roller a77 disposed on the single pre-support clamping connecting plate a74, and a single pre-support clamping roller a77 disposed on the single pre-support clamping connecting plate a74 and located on the single pre-support clamping roller a77. A single pre-support clamping actuator a75 is located on the side of 77. A single pre-support clamping block a76 is provided on the telescopic end of the single pre-support clamping actuator a75. The single pre-support clamping block a76 moves up and down relative to the single pre-support clamping roller a77 under the drive of the single pre-support clamping actuator a75 to release or clamp the wrist arm tube. The single pre-support clamping block a76 rotates relative to the single pre-support clamping actuator a75 under the drive of the single pre-support clamping actuator a75.

[0055] Furthermore, a single pre-support pressing lifting drive a72 and a single pre-support pressing connecting plate a74 are provided with a single pre-support pressing lifting plate a73, which is used to provide a sliding track for the single pre-support pressing connecting plate a74 to move up and down relative to the single pre-support pressing lifting drive a72.

[0056] In this embodiment, the reason for setting up a single pre-support clamping lifting driver a72 is that when the single pre-support clamping connecting plate a74 and its single pre-support clamping roller a77 are in the position supporting the arm tube, they will interfere with the conveying of the arm tube, especially the conveying of the arm tube equipped with a single ear. Similarly, the reason for setting up a single pre-support clamping block a76 to rotate relative to the single pre-support clamping driver a75 under the drive of the single pre-support clamping driver a75 is also to avoid interference of the single pre-support clamping module a7 with the conveying of the arm tube. The reason for setting up a single pre-support clamping block a76 to move up and down relative to the single pre-support clamping roller a77 under the drive of the single pre-support clamping driver a75 to loosen or clamp the arm tube is to ensure the stability of the arm tube when the single pre-tightening module a4 locks the single ear and the arm tube, and to prevent the arm tube from shifting due to locking.

[0057] Example 3:

[0058] Based on Example 1 or 2, refer to Figure 3 As shown, the single pre-tensioned tube module a3 includes a single pre-tensioned tube base a31 disposed on the single pre-rail module a1, a single pre-tensioned tube moving driver a33 disposed on the single pre-tensioned tube base a31 and driving the single pre-tensioned tube base a31 to move relative to the single pre-rail module a1, and a single pre-tensioned tube support a32 disposed on the single pre-tensioned tube base a31. The single pre-tensioned tube support a32 is provided with a single pre-tensioned tube clamping driver a36. The single pre-tensioned tube clamping driver a36 drives the single pre-tensioned tube gripper a37 to clamp or release to hold or release the wrist arm tube.

[0059] Furthermore, the single pre-tensioned tube support a32 is provided with a single pre-tensioned tube connecting plate a34, and the single pre-tensioned tube clamping driver a36 is provided on the single pre-tensioned tube support a32 through the single pre-tensioned tube connecting plate a34.

[0060] Furthermore, the single pre-tensioned tube connecting plate a34 is provided with a single pre-tensioned tube rotary driver a35, and the single pre-tensioned tube clamping driver a36 is connected to the single pre-tensioned tube rotary driver a35. The single pre-tensioned tube rotary driver a35 drives the single pre-tensioned tube clamping driver a36 to rotate, thereby driving the wrist arm tube held by the single pre-tensioned tube gripper a37 to rotate.

[0061] In this embodiment, the reason why the single pre-tensioned tube gripper a37 needs to be set on the single pre-tensioned tube support a32 via the single pre-tensioned tube connecting plate a34 is to avoid interference from the single pre-support clamping module a7 and the single pre-support frame module a2 on the single pre-tensioned tube module a3 when conveying the cantilever tube; the reason why the single pre-tensioned tube rotary driver a35 is needed to drive the single pre-tensioned tube clamping driver a36 to rotate, thereby driving the cantilever tube held by the single pre-tensioned tube gripper a37 to rotate is... Because the orientation of the single ear b6 installed on the carousel tube is required, that is, some bolts of the single ear b6 face upwards and some face downwards, and the single pre-tightening module a4 can only lock the downward-facing bolts, when the bolts of the single ear b6 need to face upwards, the single pre-tension tube rotary driver a35 drives the single pre-tension tube clamping driver a36 to rotate, thereby driving the carousel tube held by the single pre-tension tube gripper a37 to rotate. At this time, after locking the bolts of the single ear b6, the carousel tube is rotated again, and the bolts of the single ear b6 will meet the requirement of facing upwards.

[0062] Example 4:

[0063] Based on any of the foregoing embodiments, refer to Figure 4 As shown, it also includes a single pre-fixed support module a5, which is located on the side of the single pre-rail module a1 near the end of the single pre-support clamping module a7. The single pre-fixed support module a5 and the multiple single pre-support clamping modules a7 are located on the same straight line. The single pre-fixed support module a5 is equipped with a single pre-fixed support marking machine a57, which is used to mark the cartilage tube.

[0064] Furthermore, the single pre-fixed support module a5 includes a single pre-fixed support column a51, a single pre-fixed support connecting plate a52 and a single pre-fixed support mounting plate a54 disposed on the single pre-fixed support column a51. The single pre-fixed support connecting plate a52 is provided with a single pre-fixed support roller a53 for supporting the arm tube. The single pre-fixed support mounting plate a54 is provided with a single pre-fixed support telescopic actuator a55. The telescopic end of the single pre-fixed support telescopic actuator a55 is provided with a single pre-fixed support moving plate a56. The single pre-fixed support marking machine a57 ​​is disposed on the single pre-fixed support moving plate a56.

[0065] In this embodiment, the single pre-fixed support marking machine a57 ​​can mark information such as the installation position, structural features, specifications, and production date of the aluminum cantilever arm on the cantilever tube, thereby facilitating the subsequent use and maintenance of the aluminum cantilever arm; the single pre-fixed support roller a53 can be used to support the cantilever tube; the single pre-fixed support telescopic driver a55 can adjust the distance between the single pre-fixed support marking machine a57 ​​and the cantilever tube, thereby facilitating marking, and can also extend to mark when marking is needed and retract when marking is not needed to avoid interference with the conveying of the cantilever tube.

[0066] Example 5:

[0067] Based on any of the foregoing embodiments, refer to Figure 8 and Figure 13 As shown, the single-ear conveying device b includes a single-ear conveying base b1, and a single-ear drive motor b2 is installed on one side of the single-ear conveying base b1; a single-ear conveying frame b3 is installed above the single-ear conveying base b1, and a single-ear rotary conveying device is installed on the single-ear conveying frame b3; several single-ear storage racks b5 are horizontally arranged side by side on the single-ear rotary conveying device, and each single-ear storage rack b5 includes several vertically arranged single-ear storage units b51. Each single-ear storage unit b51 is used to place a single ear b6, and each single-ear storage unit b51 includes a single-ear connecting portion receiving groove b512 and a single ear connecting portion receiving groove b512 located respectively. 2. Single ear collar positioning components b511 on the front and rear sides. After the single ear b6 is placed on the single ear storage unit b51, the two single ear collar ends b621 of the single ear collar b62 are respectively placed in the single ear collar positioning component b511, and the single ear connecting part b63 is placed in the single ear connecting part receiving groove b512. The single ear drive motor b2 is connected to the single ear rotary conveyor. The single ear drive motor b2 drives the single ear rotary conveyor to rotate. The single ear rotary conveyor drives the single ear storage rack b5 installed on it to rotate. The single ear b6 placed on the single ear storage rack b5 is continuously supplied with replenishment material to the aluminum cantilever production line.

[0068] In this embodiment, the single-ear conveyor base b1 supports the entire single-ear conveying device, and the single-ear drive motor b2 provides power to the single-ear rotary conveyor. When the single-ear conveying device is working, the operator places the single ear b6 on the single-ear storage rack b5. The single-ear drive motor b2 drives the single-ear rotary conveyor to rotate, conveying the single ear b6 to the target position. Then, the single-ear picking module a8 fixes and picks up the single ear b6 and transfers it to the next workstation, thereby realizing the continuous supply of single ear b6 in the aluminum cantilever production line.

[0069] like Figure 13As shown, the single ear b6 includes a single ear platform part b61, a single ear collar b62 and a single ear connecting part b63. ​​The two ends of the single ear collar b62 extend out of the bottom surfaces of the two ends of the single ear platform part b61 and are locked and fixed by nuts, and are longitudinally located at the lower end of the single ear platform part b61. The difficulty in automating the transport of a single ear b6 with the aforementioned specific shape lies in the fact that the arm tube needs to be inserted into the circular space enclosed by the single ear collar b62 and the single ear platform b61. When the single ear picking module a8 grasps the single ear b6, it needs to avoid the left and right sides of the single ear b6 and can only grasp it from the front and back sides. The thickness between the front and back sides of the single ear connecting part b63 is relatively thin, making it difficult to grasp and fix. Therefore, it is necessary to grasp and fix the front and back sides of the single ear platform b61 or the single ear collar b62. Thus, when placing the single ear b6, the single ear connecting part b63 needs to be placed downwards, and the shaking of the single ear b6 must be avoided during the transport process.

[0070] Therefore, in this embodiment, the single ear storage rack b5 is provided with a single ear storage unit b51, and the single ear storage unit b51 is provided with a single ear connecting part receiving groove b512 for receiving the downward protruding single ear connecting part b63. ​​Two single ear collar positioning parts b511 are used to receive the ends of the single ear collars, which support the single ear b6 while restricting the single ear b6's degrees of freedom except for vertical movement, ensuring the placement stability of the single ear b6 during the conveying process. After the single ear b6 is placed on the single ear storage rack b5, the single ear collar b62 is exposed above the single ear storage rack b5, which is convenient for the single ear picking module a8 to grasp, thereby facilitating the automated replenishment of the single ear b6. The single ear b6 is placed longitudinally on the single ear storage rack b5, which allows more single ears to be accommodated in the horizontal direction, making the structure more compact. Moreover, the single ear storage rack b5 is provided with different numbers of single ear storage units b51 according to needs, which shortens the overall length of the production line while meeting the production line's production requirements.

[0071] This embodiment achieves continuous material supply to single ears b6 with a specific structure by setting up a single ear storage rack b5 with a special structure. This solves the problem in the prior art that the lack of a dedicated storage rack for single ears makes it impossible to achieve automated material supply to single ears, thus providing technical support for the automated production of aluminum cantilever arms.

[0072] Furthermore, the single-ear collar positioning component b511 has a single-ear positioning stepped groove b5111 in the middle, and the single-ear positioning stepped groove b5111 matches the size of the single-ear collar end b621 after it is assembled with the nut.

[0073] Furthermore, the single ear storage unit b51 on the single ear storage holder b5 is two.

[0074] Example 6:

[0075] Based on Example 5, referring to Figure 9 As shown, the single-ear rotary conveying device includes a single-ear conveying driven shaft b48 and a single-ear conveying driving shaft b47, which are respectively longitudinally installed at the left and right ends of the single-ear conveying frame b3. The front and rear ends of the single-ear conveying driving shaft b47 are respectively equipped with single-ear conveying driving wheels b44, and the front and rear ends of the single-ear conveying driven shaft b48 are respectively equipped with single-ear conveying driven wheels b45. The single-ear conveying driving wheel b44 and the single-ear conveying driven wheel b45 located on the same side of the single-ear conveying frame b3 are connected by a single-ear conveying transmission chain b46. The single-ear drive motor b2 is connected to the single-ear conveying driving shaft b47, and the two ends of the single-ear storage rack b5 are respectively installed on the two single-ear conveying transmission chains b46.

[0076] Furthermore, refer to Figure 11 As shown, a single-ear conveyor chain b46 is provided on one side of a single-ear conveyor chain side bracket b463, and the two ends of the single-ear storage rack b5 are respectively fixedly connected to the single-ear conveyor chain side bracket b463.

[0077] Furthermore, the front and rear sides of the single ear storage rack b5 are respectively provided with a single ear storage rack overlapping platform Ib52 and a single ear storage rack overlapping platform IIb53, which are respectively overlapped and installed on the single ear transmission chain side bracket b463.

[0078] Furthermore, the single ear storage rack mounting platform Ib52 and the single ear storage rack mounting platform IIb53 are respectively provided with single ear storage rack mounting holes b54.

[0079] Furthermore, the single-ear delivery frame b3 includes a plurality of single-ear frame support shafts b33 and single-ear frame side plates Ib31 and IIb32 located on the front and rear sides of the single-ear frame support shafts b33 and fixedly connected to the single-ear frame support shafts b33.

[0080] In this embodiment, the single-ear conveying frame b3 adopts a structure with two side plates and a support shaft, which can reduce the weight of the frame and save the frame material while ensuring the support stability of the frame. At the same time, it can avoid the position of the single-ear rotary conveying device, making the structure of the whole device more compact.

[0081] Furthermore, the output end of the single-ear drive motor b2 is connected to a single-ear drive drive wheel b41, and one end of the single-ear conveying drive shaft b47 is connected to a single-ear drive driven wheel b42. The single-ear drive drive wheel b41 and the single-ear drive driven wheel b42 are connected through a single-ear drive transmission chain b43.

[0082] In this embodiment, the output shaft of the single-ear drive motor b2 rotates, causing the single-ear drive drive wheel b41 to rotate. Then, the single-ear drive driven wheel b42 rotates through the single-ear drive transmission chain b43, thereby driving the single-ear conveying drive shaft b47 to rotate. This causes the single-ear conveying drive wheels b44, which are installed at both ends of the single-ear conveying drive shaft b47, to rotate. Then, the single-ear conveying driven wheel b45 rotates through the single-ear conveying transmission chain b46, thereby achieving continuous and stable rotation of the single-ear conveying transmission chain b46. This continuously conveys the single ear b6 located above the single-ear conveying transmission chain b46 to the target position.

[0083] Furthermore, the single-ear drive motor b2 is a right-angle output motor. A right-angle output motor saves more front and rear space in the entire device, making the overall structure more compact and reducing the footprint of the device, thereby saving space in the entire production line.

[0084] Furthermore, refer to Figure 10 As shown, a single-ear conveying guide bar b35 is installed on the single-ear conveying frame b3 below the single-ear conveying transmission chain b46. The upper end of the single-ear conveying guide bar b35 is provided with a boss. The boss is placed between the inner side plates b461 of the single-ear transmission chain on both sides of the single-ear conveying transmission chain b46, and the width of the boss matches the length of the single-ear transmission chain central shaft b462 of the single-ear conveying transmission chain b46.

[0085] In this embodiment, the single-ear conveying guide strip b35 serves two purposes. First, it supports the bottom of the single-ear conveying transmission chain b46, preventing it from bending and deforming due to the weight of the single-ear storage rack b5 and the single ear b6. This avoids affecting the service life of the single-ear conveying transmission chain b46 and the efficiency of the single-ear conveying device. Second, the boss is positioned between the inner side plates b461 of the single-ear transmission chain on both sides of the single-ear conveying transmission chain b46, and the width of the boss matches the length of the central shaft b462 of the single-ear transmission chain. This allows the boss to guide the movement of the single-ear conveying transmission chain b46, preventing it from swaying or shifting during movement, thus making the rotational conveying of the single ear smoother and more stable.

[0086] Furthermore, a single-ear conveying support plate b34 is installed between the two side plates of the single-ear conveying frame b3, and the single-ear conveying guide strip b35 is installed above the single-ear conveying support plate b34.

[0087] Example 7:

[0088] Based on embodiment 5 or 6, a plurality of single ear position sensors b71 are installed on one side of the single ear delivery frame b3. The height of the single ear position sensor b71 matches the height of the single ear b6. The single ear position sensor b71 is used to detect whether a single ear b6 is placed on the single ear storage rack b5.

[0089] In this embodiment, when the single ear position sensor b71 detects that there is no single ear b6 on the single ear storage rack b5, the control system reminds the staff to replenish the single ear b6 on the single ear storage rack b5 in a timely manner.

[0090] Furthermore, a single ear detection reader b74 is installed on one side of the single ear delivery frame b3, and a single ear storage rack b55 is provided on one side of the single ear storage rack b5. The position of the single ear storage rack b55 matches the position between the transmitting end and the receiving end of the single ear detection reader b74.

[0091] In this embodiment, the single-ear detection reader b74 is used to count the number of single-ear storage racks b5. When the single-ear storage rack b55 on the single-ear storage rack b5 passes between the transmitter and receiver of the single-ear detection reader b74, it blocks the signal transmitted from the transmitter to the receiver. At this time, the single-ear detection reader b74 counts a number. The control system calculates the number of supplied single earbuds b6 by using the number of single-ear storage racks b5 recorded by the single-ear detection reader b74.

[0092] Furthermore, a single ear zero-position sensor b72 is installed on one side of the single ear delivery frame b3, and a single ear zero-position detection piece b73 matching the position of the single ear zero-position sensor b72 is installed on one of the single ear storage racks b5.

[0093] In this embodiment, when the single-ear delivery device starts working, the operator places the first single ear b6 on the single-ear storage rack b5 equipped with the single-ear zero-position detection chip b73, and then adds single ears b6 to subsequent single-ear storage racks b5 one after another. When the single-ear storage rack b5 equipped with the single-ear zero-position detection chip b73 passes the single-ear zero-position sensor b72, the single-ear zero-position sensor b72 sends a signal to the control system, and the control system controls the single-ear detection reading head b74 to start counting. In this way, the number of single-ear storage racks b5 without single ears b6 can be avoided, thereby improving the counting accuracy of the single-ear detection reading head b74.
