The dividing plate 102 is rotatably mounted on the frame 3. A profiled needle guard block 103 is arranged on the front side of the profiled material receiving groove 101. Figure 3As shown, the profiling needle guard block 103 is a fixed block with a through groove that matches the needle piece. During the assembly process, the needle piece passes through the through groove and is plugged into the copper seat. The profiling needle guard block 103 is fixedly installed on the front end surface of the dividing plate 102. The loading station, the copper seat detection station, the assembly station and the unloading station are arranged in sequence along the circumference of the dividing plate 102, and the aforementioned four stations are respectively located on the left side, top side, right side and bottom side of the dividing plate 102. The assembly mechanism 2 includes a dividing component 21 and a pushing component 22. During the assembly process, the copper seat enters the profiling receiving groove 101 from the loading station and then passes through the copper seat detection station to complete the copper seat detection before entering the assembly station. At the same time, the dividing component 21 sends the needle piece to the front side of the copper seat in the assembly station and aligns it with the copper seat. After that, the pushing component 22 pushes the needle piece in the dividing component 21 from front to back, so that the needle piece passes through the profiling needle guard block 103 and is inserted into the copper seat.

[0028] See also Figure 1 , Figure 2 and Figure 4 A copper seat loading component 104 is provided at the loading station, a copper seat detection component 107 is provided at the copper seat presence or absence detection station, a material receiving component 105 is provided at the unloading station, the assembly mechanism 2 is located at the assembly station, and a needle loading component 106 is also provided at the assembly station. During the assembly process, the dividing plate 102 rotates intermittently so that the profiling material receiving trough 101 first passes through the loading station to cut the copper seat, and then passes through the copper seat detection station to detect whether the profiling material receiving trough 101 has a copper seat, and then enters the assembly station. At the same time, the needle loading component 106 sends the needle to the dividing component 21, and the dividing component 21 sends the needle to a position aligned with the copper seat in the assembly station, and then the pushing component 22 pushes the needle in the dividing component 21, so that the needle passes through the profiling needle guard block 103 and is inserted into the corresponding copper seat, and finally enters the unloading station to complete the unloading of the assembled product.

[0029] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6 , Figure 7 and Fig.10, the needle feeding assembly 106 includes a needle circular vibration plate 116 and a needle straight vibration track 126, the outlet of the needle straight vibration track 126 corresponds to the material dividing assembly 21, the material dividing assembly 21 includes a flexible material pushing member 211, a limit block 212, a material dividing cylinder 214 connected to a needle material dividing block 213, and a pressing block 216, the needle material dividing block 213 is provided with a needle placement slot 215, the pressing block 216 is fixedly mounted on the frame 3 and is located above the needle material dividing block 213, the needle material dividing block 213 is slidably mounted on the frame 3 left and right, the limit block 212 is slidably mounted on the pressing block 216 front and back, the flexible material pushing member 211 is mounted on the pressing block 216, the needle straight vibration track 126 is located on the rear side of the needle material dividing block 213, during the needle removal process, such as Figure 5 As shown, the needle placing groove 215 on the needle member dividing block 213 is connected to the outlet of the needle member straight vibration track 126. The needle member identifies the direction of the needle member circular vibration plate 116 and enters the needle member straight vibration track 126 in the direction of assembly. Then, the needle member moves forward with the vibration of the needle member straight vibration track 126 and passes through the outlet to enter the needle placing groove 215. After that, the flexible pushing member 211 moves forward to contact the needle member in the needle placing groove 215 and applies a flexible thrust to move the needle member forward until it abuts against the limit block 212 on the front side. Then, it continues to move to release the contact with the needle piece and pushes the limit block 212 forward to separate the limit block 212 from the needle piece. At this time, the needle piece stays stably and accurately in the needle placement slot 215, and then the dividing cylinder 214 moves the needle piece dividing block 213 to the left to send the needle piece in the needle placement slot 215 to the front of the copper seat and align it with the copper seat. The above process can stably and reliably complete the removal and delivery of the needle piece, improve the stability and reliability of the automated assembly process, and correspondingly help to improve the stability and reliability of the finished product quality.

[0030] See also Figure 6 , Figure 7 and Figure 8 The flexible pusher 211 includes a horizontal slider 2111 and a track groove 2112. The horizontal slider 2111 is slidably mounted on the pressing block 216. The track groove 2112 is mounted on the pressing block 216 and includes an arc portion and a horizontal portion. Figure 7As shown, the horizontal parts are symmetrically distributed front to back and are respectively located at the front and rear sides of the arc-shaped part. The horizontal slider 2111 is vertically slidably connected with a vertical slider 2113. The vertical slider 2113 includes a cylindrical limiting part and a rectangular sliding part. The cylindrical limiting part moves along the track groove 2112. The rectangular sliding part is vertically slidably connected with the horizontal slider 2111.

The material distribution group Component 21 also includes a pushing member 217 for controlling the forward movement of the horizontal slider 2111. After the needle member enters the needle placement slot 215, the horizontal slider 2111 moves forward. When the vertical slider 2113 moves along with the horizontal slider 2111 through the arc portion of the track slot 2112, the flexible contact head 2114 moves downward to contact the needle member and applies a thrust to the needle member as the horizontal slider 2111 moves, so that the needle member moves forward and abuts against the limit block 212. Then, the vertical slider 2113 enters the horizontal portion of the track slot 2112 to release the thrust. At this time, the horizontal slider 2111 pushes the limit block 212 to keep the limit block 212 away from the needle member. Figure 8 As shown, a raised limiting portion is provided under the transverse slide block 2111. As the transverse slide block 2111 moves forward, the raised limiting portion limits the limiting block 212 to separate it from the needle member. At this time, the needle member is stably located in the needle placement slot 215, and then the needle member is fed to the left, the pushing member 217 is reset, and the transverse slide block 2111 and the limiting block 212 are both reset under the action of the elastic member 2115. Among them, a limiting member 218 is provided on the pressing block 216, and the number of limiting members 218 is two and they limit the limiting block 212 and the transverse slide block 2111 from the rear end respectively, so that the limiting block 212 and the transverse slide block 2111 are accurately reset under the action of the elastic member 2115, and the limiting force of the corresponding elastic member 2115 on the limiting block 212 after the reset is greater than the thrust applied to the needle member by the flexible contact head 2114, and then when the needle member is against the limiting block 212, the limiting block 212 can stably limit the needle member.

[0031] See also Figure 1 and Figure 4 The material receiving assembly 105 includes a qualified product collection box 115, an unqualified product collection box 125 and a material receiving cylinder 135. The material receiving cylinder 135 controls the qualified product collection box 115 and the unqualified product collection box 125 to move left and right. When unqualified products need to be collected, the material receiving cylinder 135 controls the qualified product collection box 115 and the unqualified product collection box 125 to move left, so that the unqualified product collection box 125 is located at the unloading station. When qualified products need to be collected, the material receiving cylinder 135 controls the qualified product collection box 115 and the unqualified product collection box 125 to move right, so that the qualified product collection box 115 is located at the unloading station.

[0032] See also Figure 1 , Figure 2 and Figure 3 The copper seat feeding assembly 104 includes a copper seat circular vibration plate 114, a copper seat straight vibration track 124 and a docking track 134. The copper seat circular vibration plate 114 and the copper seat straight vibration track 124 are both installed on the frame 3. After the copper seat circular vibration plate 114 identifies the direction, the copper seat is arranged in the direction of assembly and enters the copper seat straight vibration track 124. The outlet of the copper seat straight vibration track 124 is docked with the docking track 134. Figure 3 As shown, the copper seat is pushed into the docking track 134 by the thrust of the copper seat in the copper seat straight vibration track 124 and enters the contoured receiving groove 101 in the loading station through the docking track 134, and then the dividing plate 102 rotates to make the copper seat pass through the subsequent processing stations in sequence.

[0033] See also Figure 1 , Figure 2 , Figure 4 and Figure 5 , see Figure 1 , Figure 2 , Figure 4 and Figure 5 The position where the needle material dividing block 213 and the needle material feeding component 106 are connected is the needle material detection station.

The CCD camera system acquires an image by photographing the needle in the needle slot 215 and analyzes and processes the image to determine whether the length and width of the needle are qualified. When the needle is unqualified, the CCD camera system feeds back the unqualified signal to the main controller. The main controller controls the alarm to alarm and shut down the equipment or controls the receiving cylinder 135 to work, so that the unqualified product collection box 125 moves to the unloading station for receiving the material and screens out the abnormal products. The copper seat presence detection component 107 is a distance sensor at The distance sensor processing system has the function of collecting distance information and processing it. It determines whether there is a copper seat in the profiling receiving trough 101 by detecting the distance between the distance sensor and the circumferential surface of the dividing plate. When the detection distance is greater than the preset threshold, it indicates that there is no copper seat in the profiling receiving trough 101. At this time, the distance sensor processing system feeds back this signal to the main controller. The main controller controls the alarm to sound and shuts down the equipment or controls the receiving cylinder 135 to work, so that the unqualified product collection box 125 moves to the unloading station for material receiving and screens out abnormal products. The preset threshold is the minimum distance between the outer circumference of the dividing plate and the distance sensor. The main controller controls the alarm to sound and shuts down the equipment or controls the receiving cylinder 135 to work. Among them, the main controller chooses to control the alarm to sound and shuts down the equipment or controls the receiving cylinder 135 to work according to actual needs.

[0034] See also Figure 2 Figure 3 , Figure 4 , Figure 5 and Fig. 9 The push assembly 22 includes a pressure sensor 221, a push pin cylinder 223 connected to a push pin block 222, and a processor. The push pin block 222 is slidably mounted on the frame 3. A push pin head 224 matching the needle placement slot 215 is fixedly provided below the push pin block 222. The push pin cylinder 223 controls the push pin block 222 to move forward and backward. When the material distribution cylinder 214 pushes the needle material distribution block 213 to the position where the needle placement slot 215 is aligned with the push pin head 224 and the needle placement slot 215 is located below the push pin block 222, the push pin block 222 is moved backward to push the needle through the push pin head 224, so that the needle passes through the contoured needle guard block 1 03 When the copper seat is inserted, the front end of the push-pin cylinder 223 will contact the pressure sensor 221. The pressure sensor 221 collects data on the pressure changes of the needle and the copper seat and transmits the data to the processor. The processor processes the collected data and determines whether the insertion force is within the preset range. If not, it means that the assembly quality of the needle and the copper seat is unqualified. The processor sends an unqualified signal to the main controller, which controls the alarm and shuts down the equipment or controls the material receiving cylinder 135 to work, so that the unqualified product collection box 125 moves to the unloading station to receive the material and screen out the abnormal products.
