[0048] As mentioned above, in modern electronic devices, circuit boards serve as the core carrier, responsible for integrating various electronic components. To achieve electrical connections and signal transmission between different circuit boards and between circuit boards and peripheral modules, flat cables, due to their excellent flexibility, lightweight, and thinness, have become indispensable interconnect components. Currently, flat cables are manually soldered to circuit boards, and the soldering quality is manually inspected after soldering. However, manually soldering flat cables to circuit boards and manually inspecting the soldering quality after soldering is labor-intensive, and the yield rate of finished products obtained through manual soldering is low. Furthermore, manual soldering quality inspections have a high error rate and are time-consuming, resulting in low production efficiency.

[0049] In order to solve the aforementioned technical problems, in an embodiment of the present application, the welding equipment includes a robotic arm, a loading platform, a welding platform and a quality inspection platform. The robotic arm can pick up the cables and circuit boards to be welded from the loading platform and transport them to the welding platform. The welding platform can weld the cables and circuit boards. The robotic arm can transport the finished welded products obtained after the welding on the welding platform is completed to the quality inspection platform. The quality inspection platform can judge the welding quality of the finished welded products, thereby realizing automated welding and automated quality inspection. Compared with the manual welding and manual quality inspection solutions in the prior art, since automated welding and automated quality inspection are realized through welding equipment, manual welding and quality inspection are not required, the degree of automation is high and the labor intensity is low. Moreover, the quality inspection model can ensure the accuracy of quality inspection while having high quality inspection efficiency, thereby improving production efficiency.

[0050] The welding equipment, welding method, electronic device and storage medium provided in the embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0051] Figure 1 Schematic diagram of a welding device 10 provided in an embodiment of the present application. The welding device 10 is used to weld a cable to a circuit board, such as Figure 1 As shown, the welding equipment 10 includes a robotic arm 12 , a loading platform 11 , a welding platform 13 and a quality inspection platform 14 .

[0052] The loading platform 11 can be used to place the cables and circuit boards to be welded. The cables can be flexible printed circuits (FPCs) and the circuit boards can be printed circuit boards (PCBs). After the cables are welded to the circuit boards, the circuit boards and the cables are electrically connected, and the circuit boards can transmit electrical signals through the cables.

[0053] The robotic arm 12 can grab the cables and circuit boards to be soldered from the loading platform 11. It should be understood that due to the small size and thickness of the cables and circuit boards, the robotic arm 12 can grab the cables and circuit boards from the loading platform 11 by suction. Specifically, the robotic arm 12 can be connected to an air supply device that provides negative pressure to the robotic arm 12, enabling the robotic arm 12 to pick up the cables and circuit boards. Optionally, the robotic arm 12 can pick up one cable or one circuit board at a time, or it can pick up one cable and one circuit board at a time. The specific suction mechanism can be customized as needed.

[0054] After the robotic arm 12 picks up the cable and circuit board, it transports them to the soldering station 13. In one example, the robotic arm 12 may include a connecting rod and multiple sets of rotary joints and / or translational joints. The robotic arm 12 can drive the connecting rod to move the cable and circuit board to the soldering station 13 by rotating the rotary joints and / or translating the translational joints.

[0055] The welding table 13 can weld the cables and circuit boards transported by the robotic arm 12. The welding method of the welding table 13 can be soldering, laser welding, etc. The relative position between the cables and the circuit board can be fixed by welding, and the cables and the circuit board can be electrically connected. After the welding is completed on the welding table 13, the robotic arm 12 can absorb the welded product from the welding table 13, and then transport the welded product welded by the welding table 13 to the quality inspection table 14.

[0056] The quality inspection station 14 may include an image acquisition unit. After the robotic arm 12 transports the finished welded product to the quality inspection station 14, the image acquisition unit of the quality inspection station 14 may capture an image of the finished welded product. The image is then input into a pre-trained quality inspection model. The quality inspection model may perform image recognition on the product image to identify the welded area included in the product image. The model then performs feature extraction on the welded area image to determine the weld quality of the welded area. Optionally, pre-set quality inspection acceptance criteria may be provided. These criteria may include, for example, the amount of solder used, the presence of weld breakpoints, and the like.

[0057] The quality inspection table 14 further includes a mobile unit, which can be another robotic arm. The mobile unit can place finished welded products that pass quality inspection in the finished product area and unqualified welded products in the scrap area. It should be understood that, compared to the solution of using the robotic arm 12 to place finished welded products that pass quality inspection on the quality inspection table 14 in the finished product area and unqualified welded products in the scrap area, the inclusion of the mobile unit in the quality inspection table 14 allows the mobile unit to place finished welded products that pass quality inspection in the finished product area and unqualified welded products in the scrap area without affecting the working rhythm of the robotic arm 12, thereby improving welding efficiency.

[0058] The cooperation of various parts of the welding device 10 can be controlled by a controller. In one example, the controller can be a programmable controller (PLC).

[0059] In an embodiment of the present application, the welding equipment 10 includes a robotic arm 12, a loading platform 11, a welding platform 13, and a quality inspection platform 14. The robotic arm 12 can pick up the cables and circuit boards to be welded from the loading platform 11 and transport them to the welding platform 13. The welding platform 13 can weld the cables and circuit boards. The robotic arm 12 can transport the finished welded product obtained after welding at the welding platform 13 to the quality inspection platform 14. The quality inspection platform 14 can judge the welding quality of the finished welded product, thereby realizing automated welding and automated quality inspection. Compared with the manual welding and manual quality inspection solutions in the prior art, since automated welding and automated quality inspection are realized by the welding equipment 10, manual welding and quality inspection are not required, the degree of automation is high and the labor intensity is low. Moreover, the quality inspection model can ensure the accuracy of quality inspection while having a high quality inspection efficiency, thereby improving production efficiency.

[0060] In one possible implementation, Figure 2 The loading platform 11 shown includes two loading mechanisms 110 . The loading mechanism 110 includes a lifting unit 112 , a loading unit 111 and a sensing unit 113 .

[0061] The loading units 111 can carry materials 20 stacked in a vertical direction. The materials 20 include cables or circuit boards. The loading units 111 included in the two loading mechanisms 110 carry the cables and circuit boards respectively.

[0062] The sensing unit 113 can sense the position of the top material carried by the loading unit 111 and send a lifting signal to the lifting unit 112 when the top material is below the target position. The top material is the material 20 stacked on top of the materials 20 stacked in the vertical direction. Optionally, the sensing unit 113 can be a diffuse reflection laser sensor. The diffuse reflection sensor can emit a light signal to the top material, receive the reflected light diffusely reflected by the surface of the top material, and convert the received reflected light into an electrical signal. The electrical signal is the lifting signal. When the signal strength of the electrical signal is less than the intensity threshold, it proves that the top material is below the target position.

[0063] The lifting unit 112 can drive the loading unit 111 to rise according to the lifting signal. For example, when the sensing unit 113 can be a diffuse reflection laser sensor, when the lifting unit 112 receives a low-level signal, it proves that the top material is below the target position. At this time, the lifting unit 112 drives the loading unit 111 to rise, so that the top material rises until it reaches the target position.

[0064] In an embodiment of the present application, the loading mechanism 110 includes a lifting unit 112, a loading unit 111 and a sensing unit 113. The loading unit 111 can carry stacked materials 20. The sensing unit 113 can sense the position of the top material and send a lifting signal to the lifting unit 112 when the top material is below the target position. The lifting unit 112 can drive the loading unit 111 to rise based on the lifting signal so that the top material reaches the target position, thereby ensuring that the top material is located at a position where the robotic arm 12 can absorb it, so that the robotic arm 12 can absorb the material 20 from the loading unit 111, preventing the robotic arm 12 from being unable to absorb the material 20 due to the low height of the material 20. There is no need to manually adjust the height of the material 20, and the degree of automation is high.

[0065] In one possible implementation, Figure 3 The structure of the robot arm 12 shown in FIG. 1 includes a robot arm body 121 , a suction unit 122 and a clamping unit 123 .

[0066] The robot body 121 is connected to the base of the robot arm 12, and the suction unit 122 and the clamping unit 123 are connected to the end of the robot body 121. Optionally, the robot body 121 may include a connecting rod and multiple sets of rotational joints and / or translational joints, and the movement of the end of the robot arm 12 can be controlled by the rotation of the rotational joints and / or the translation of the translational joints.

[0067] To absorb a cable or circuit board to be soldered, the robot arm 121 drives the suction unit 122 to the loading platform 11. Once there, the suction unit 122 absorbs the cable and / or circuit board to be soldered. To absorb a finished soldered product, the robot arm 121 drives the suction unit 122 to the soldering platform 13. Upon reaching the soldering platform 13, the suction unit 122 absorbs the finished product. Optionally, the suction unit 122 can receive gas through a pipe, using the gas to perform the suction function.

[0068] The clamping unit 123 can clamp the flux coating member. In one example, the flux coating member can be a pen-shaped flux coating member whose coating head is a pen tip. The flux coating member can contain flux, and the flux can be organic flux, inorganic flux, resin flux, etc. After the robot body 121 drives the suction unit 122 to transport the circuit board to the welding station 13, the clamping unit 123 can move in the direction close to the circuit board to drive the flux coating member to move in the direction close to the circuit board until the coating head of the flux coating member moves to the welding area of ​​the circuit board. Optionally, the clamping unit 123 can drive the flux coating member to move in the direction close to the circuit board until the coating head of the flux coating member abuts against the welding area of ​​the circuit board.

[0069] After the flux applicator's coating head moves to the soldering area of ​​the circuit board, the robot arm body 121 can drive the clamping unit 123 to move, thereby driving the flux applicator's coating head to move within the soldering area, allowing the flux applicator to apply flux to the soldering area through the coating head. After the flux applicator completes the flux coating, the clamping unit 123 moves away from the circuit board to drive the flux applicator away from the circuit board, completing the flux coating process.

[0070] After the clamping unit 123 drives the flux coating part to move away from the circuit board, the suction unit 122 can place the cable on the welding table 13, and the welding area of ​​the cable overlaps with the welding area on the circuit board coated with flux, so that the welding table 13 can weld the cable to the circuit board.

[0071] In an embodiment of the present application, the robotic arm 12 includes a robotic arm body 121, a suction unit 122 and a clamping unit 123. The robotic arm body 121 can drive the suction unit 122 and the clamping unit 123 to move. The suction unit 122 can suck the wiring and circuit board on the loading platform 11. The clamping unit 123 can clamp the flux coating part, so that the flux coating part applies the flux to the welding area of ​​the circuit board under the drive of the holding unit and the robotic arm body 121, thereby realizing the coating of the flux. The structure of the robotic arm 12 can realize the grabbing of the material 20, the transportation of the material 20 and the coating of the flux, thereby realizing automatic welding.

[0072] In one possible implementation, Figure 4 The structure of the welding station 13 shown in FIG. 1 includes a welding unit 131 and a welding turntable 132 .

[0073] The welding turntable 132 can rotate. In one example, the welding turntable 132 can rotate about its geometric center. For example, if the welding turntable 132 is a circular turntable, the welding turntable 132 can rotate about the center of the circle. The welding turntable 132 includes a first welding plate 1321 and a second welding plate 1322. The first welding plate 1321 can support a flat cable and a circuit board, and the second welding plate 1322 can also support a flat cable and a circuit board. One of the first welding plate 1321 and the second welding plate 1322 is opposite to the welding unit 131, and the other of the first welding plate 1321 and the second welding plate 1322 is opposite to the welding unit 131 after the welding turntable 132 rotates.

[0074] The welding unit 131 can weld the cable and circuit board carried by the first welding disk 1321 when the welding turntable 132 rotates to a position where the first welding disk 1321 is opposite to the welding unit 131, and weld the cable and circuit board carried by the second welding disk 1322 when the welding turntable 132 rotates to a position where the second welding disk 1322 is opposite to the welding unit 131.

[0075] The following two specific examples illustrate the welding process. It should be noted that in the following examples, the master welding pad is the pad opposite the welding unit 131. For example, if the first welding pad 1321 is opposite the welding unit 131, the first welding pad 1321 is the master welding pad, and the second welding pad 1322 is the slave welding pad. After the welding turntable 132 rotates, the second welding pad 1322 is opposite the welding unit 131. In this case, the second welding pad 1322 is the master welding pad, and the first welding pad 1321 is the slave welding pad.

[0076] In one example, if Figure 5 The finished welding structure shown, when the finished welding product includes a flat cable 22 and a circuit board 21, takes the welding turntable 132 without the flat cable 22 and the circuit board 21 as an example:

[0077] The robot body 121 drives the suction unit 122 to move to the loading platform 11. The suction unit 122 picks up a flat cable 22 and a circuit board 21 from the loading platform 11. The robot body 121 drives the suction unit 122 to move above the first welding pad 1321 (from the welding pad). The suction unit 122 places the circuit board 21 on the first welding pad 1321. The clamping unit 123 drives the flux applicator toward the circuit board 21. After the flux applicator's coating head moves to the soldering area of ​​the circuit board 21, the robot body 121 drives the clamping unit 123 to move, driving the flux applicator's coating head to move in the soldering area, so that the flux applicator applies flux to the soldering area through the coating head. After the flux applicator completes the flux coating, the clamping unit 123 drives the flux applicator away from the circuit board 21. The suction unit 122 places the flat cable 22 on the first soldering pad 1321. The welding turntable 132 rotates, and the first welding disk 1321 serves as a main welding disk and faces the welding unit 131 . The welding unit 131 welds the flat cable 22 and the circuit board 21 carried on the first welding disk 1321 .

[0078] During the soldering process of the soldering unit 131 soldering the flat cable 22 and the circuit board 21 carried on the first soldering pad 1321 (main soldering pad), the robot body 121 drives the suction unit 122 to move to the loading platform 11. The suction unit 122 sucks a flat cable 22 and a circuit board 21 from the loading platform 11. The robot body 121 drives the suction unit 122 to move above the second soldering pad 1322 (secondary soldering pad). The suction unit 122 places the circuit board 21 on the second soldering pad 1322. The clamping unit 123 drives the flux applicator to move toward the circuit board 21. After the flux applicator's coating head moves to the soldering area of ​​the circuit board 21, the robot body 121 can drive the clamping unit 123 to move, thereby driving the flux applicator's coating head to move in the soldering area, so that the flux applicator applies flux to the soldering area through the coating head. After the flux applicator completes the flux coating, the clamping unit 123 drives the flux applicator to move away from the circuit board 21. The suction unit 122 places the flat cable 22 on the second welding plate 1322. The welding turntable 132 rotates, with the second welding plate 1322 acting as the main welding plate opposite the welding unit 131. The welding unit 131 then solders the flat cable 22 and PCB 21 carried on the second welding plate 1322. The suction unit 122 then extracts the finished soldered product from the first welding plate 1321 (the secondary soldering plate). The robot body 121 then drives the suction unit 122 to transport the finished soldered product to the quality inspection station 14. The robot body 121 then drives the suction unit 122 to the loading platform 11 to extract a new flat cable 22 and PCB 21. This process repeats until the soldering task is complete.

[0079] In another example, Figure 6 The finished welding structure shown, when the finished welding product includes a flat cable 22 and two circuit boards 21, takes the welding turntable 132 without the flat cable 22 and the circuit board 21 as an example:

[0080] Step 1: The robot body 121 drives the suction unit 122 to move to the loading platform 11. The suction unit 122 picks up a flat cable 22 and a circuit board 21 from the loading platform 11. The robot body 121 drives the suction unit 122 to move above the first welding pad 1321 (from the welding pad). The suction unit 122 places the circuit board 21 on the first welding pad 1321. The clamping unit 123 drives the flux applicator toward the circuit board 21. After the flux applicator's coating head moves to the soldering area of ​​the circuit board 21, the robot body 121 drives the clamping unit 123 to move, thereby driving the flux applicator's coating head to move within the soldering area, so that the flux applicator applies flux to the soldering area through the coating head. After the flux applicator completes the flux coating, the clamping unit 123 drives the flux applicator away from the circuit board 21. The suction unit 122 places the flat cable 22 on the first soldering pad 1321. The welding turntable 132 rotates, and the first welding disk 1321 serves as a main welding disk and faces the welding unit 131 . The welding unit 131 welds the flat cable 22 and the circuit board 21 carried on the first welding disk 1321 .

[0081] Step 2: During the process of welding the flat cable 22 and the circuit board 21 carried on the first welding pad 1321 (main welding pad) by the welding unit 131, the robot body 121 drives the suction unit 122 to move to the loading platform 11, and the suction unit 122 sucks a flat cable 22 and a circuit board 21 from the loading platform 11. The robot body 121 drives the suction unit 122 to move above the second welding pad 1322 (from the welding pad), and the suction unit 122 places the circuit board 21 on the second welding pad 1322. The clamping unit 123 drives the flux coating part to move toward the direction close to the circuit board 21. After the coating head of the flux coating part moves to the welding area of ​​the circuit board 21, the robot body 121 can drive the clamping unit 123 to move, so as to drive the coating head of the flux coating part to move in the welding area, so that the flux coating part applies flux to the welding area through the coating head. After the flux coating is completed, the clamping unit 123 drives the flux coating member away from the circuit board 21. The suction unit 122 places the flat cable 22 on the second welding plate 1322. The welding turntable 132 rotates, and the second welding plate 1322 acts as the main welding plate opposite the welding unit 131. The welding unit 131 then welds the flat cable 22 carried on the second welding plate 1322 to the circuit board 21.

[0082] Step 3: During the process of welding the flat cable 22 and the circuit board 21 carried on the second welding pad 1322 (main welding pad) by the welding unit 131, the robot body 121 drives the suction unit 122 to move to the loading platform 11, and the suction unit 122 sucks a circuit board 21 from the loading platform 11. The robot body 121 drives the suction unit 122 to move above the first welding pad 1321 (from the welding pad), and sucks the welding semi-finished product (only including a flat cable 22 and a circuit board 21) from the first welding pad 1321, and places the circuit board 21 on the first welding pad 1321. Then, the clamping unit 123 drives the flux coating part to move in the direction close to the circuit board 21. After the coating head of the flux coating part moves to the welding area of ​​the circuit board 21, the robot body 121 can drive the clamping unit 123 to move, so as to drive the coating head of the flux coating part to move in the welding area, so that the flux coating part applies flux to the welding area through the coating head. After the flux coating is completed, the clamping unit 123 drives the flux coating member to move away from the circuit board 21. The suction unit 122 places the semi-finished product on the first welding plate 1321. The welding turntable 132 rotates. At this time, the first welding plate 1321 acts as the main welding plate and faces the welding unit 131. The welding unit 131 welds the circuit board 21 and the semi-finished product carried on the first welding plate 1321.

[0083] Step 4: During the process of welding the circuit board 21 and the semi-finished welding product carried on the first welding pad 1321 (main welding pad) by the welding unit 131, the robot body 121 drives the suction unit 122 to move to the loading platform 11, and the suction unit 122 sucks a circuit board 21 from the loading platform 11. The robot body 121 drives the suction unit 122 to move above the second welding pad 1322 (from the welding pad), sucks the semi-finished welding product (only including a cable 22 and a circuit board 21) from the second welding pad 1322, and places the circuit board 21 on the second welding pad 1322. Then, the clamping unit 123 drives the flux coating part to move in the direction close to the circuit board 21. After the coating head of the flux coating part moves to the welding area of ​​the circuit board 21, the robot body 121 can drive the clamping unit 123 to move, so as to drive the coating head of the flux coating part to move in the welding area, so that the flux coating part applies flux to the welding area through the coating head. After the flux coating is completed, the clamping unit 123 drives the flux coating member to move away from the circuit board 21. The suction unit 122 places the semi-finished product on the second welding plate 1322. The welding turntable 132 rotates. At this time, the second welding plate 1322 serves as the main welding plate and faces the welding unit 131. The welding unit 131 welds the circuit board 21 and the semi-finished product on the first welding plate 1321.

[0084] Step 5: While the welding unit 131 is welding the circuit board 21 and the semi-finished welding product carried on the second welding disk 1322 (main welding disk), the suction unit 122 sucks the finished welding product on the first welding disk 1321 (from the welding disk) and transports the finished welding product to the quality inspection table 14. Then the robot body 121 drives the suction unit 122 to move to the loading table 11. The suction unit 122 sucks a cable 22 and a circuit board 21 from the loading table 11. The robot body 121 drives the suction unit 122 to move to the first welding disk 1321 (from the welding disk) of the welding table 13 and repeats the process of step 4. After the welding turntable 132 rotates, the welding unit 131 is welding the cable 22 and the circuit board 21 carried on the first welding disk 1321 (main welding disk). The suction unit 122 sucks the finished welding product on the first welding disk 1321 (from the welding disk) and transports the finished welding product to the quality inspection table 14.

[0085] Repeat steps 2 to 5 above until the welding task is completed.

[0086] In the embodiment of the present application, the welding station 13 includes a welding unit 131 and a welding turntable 132. The welding turntable 132 includes a first welding plate 1321 and a second welding plate 1322. The welding turntable 132 can rotate so that the first welding plate 1321 or the second welding plate 1322 is opposite to the welding unit 131 in turn. The welding unit 131 can weld the cable 22 and the circuit board 21 carried on the relative welding plate. Therefore, when the welding unit 131 is welding the main welding plate (one of the first welding plate 1321 or the second welding plate 1322), the robot arm 12 can transport the finished welding product on the slave welding plate (the other of the first welding plate 1321 or the second welding plate 1322) and place new cables 22 and circuit boards 21 to be welded on the slave welding plate, thereby realizing alternating welding of the first welding plate 1321 and the second welding plate 1322. Therefore, the welding time of the welding unit 131 can be fully utilized to control the robot arm 12 to perform subsequent operations, thereby improving welding efficiency.

[0087] In one possible implementation, Figure 7 The structure of the welding platform 13 shown in FIG. 1 further includes a distance detection unit 133 .

[0088] The distance measurement unit is connected to the welding unit 131. After the robotic arm 12 transports the cable and circuit board to the welding station 13, the distance measurement unit can detect the distance between the welding unit 131 and the cable and / or circuit board. In one example, the distance measurement unit can be a laser rangefinder. The laser rangefinder transmits a laser signal to the cable and / or circuit board supported on the first welding pad 1321 or the second welding pad 1322 opposite the welding unit 131, and receives the reflected laser signal to determine the distance between the welding unit 131 and the cable and / or circuit board.

[0089] When the distance between the welding unit 131 and the cable and / or circuit board is outside the preset distance range, for example, when the distance is greater than the maximum value in the distance range, it proves that the robot arm 12 has not placed the cable and / or circuit board on the welding turntable 132; when the distance is less than the minimum value in the distance range, it proves that the posture of the cable and / or circuit board is not in a normal posture. At this time, an alarm signal is issued to remind manual handling of the abnormal situation.

[0090] In an embodiment of the present application, the welding station 13 also includes a distance detection unit 133. The distance detection unit 133 can send an alarm signal to remind manual processing of abnormal situations when the distance between the welding unit 131 and the cable and / or circuit board is outside a preset distance range. This can prevent the robotic arm 12 from failing to place the cable and / or circuit board on the welding turntable 132 normally, or the posture of the cable and / or circuit board is not in a normal posture, which can improve the yield of the finished welding product, prevent damage to the welding equipment 10, and reduce safety hazards.

[0091] In a possible implementation, the welding device 10 further includes a positioner 15 .

[0092] The positioner 15 can correct the position of the cable. Figure 8 The locator 15 structure shown in FIG. 1 can be formed into the shape of a cable by raised studs. After the robot arm 12 absorbs the cable from the loading unit 111, it places the cable on the locator 15. Since the locator 15 is formed into the shape of a cable by raised studs, the cable placed on the locator 15 will fall into the shape surrounded by the raised studs, realizing the position correction function. Then, after the robot arm 12 absorbs the cable after position correction, it transports the cable to the welding table 13.

[0093] In an embodiment of the present application, the welding equipment 10 also includes a positioner 15, through which the position of the wiring placed by the robot arm 12 can be corrected, so that when the robot arm 12 absorbs the position-corrected wiring and transports it to the welding table 13, the posture and position of the wiring can be guaranteed to be correct, thereby preventing the occurrence of normal welding due to incorrect posture and position of the wiring, improving the yield of the finished welding product, preventing damage to the welding equipment 10, and reducing safety hazards.

[0094] In a possible implementation, the loading mechanism 110 further includes a limiting member 114 .

[0095] like Figure 9 The illustrated structure of the position limiting member 114 includes a receiving space 1141. The horizontal cross-sectional shape of the receiving space 1141 is identical to the shape of the material 20 carried by the loading unit 111 in the loading mechanism 110. For example, when the material 20 carried by the loading unit 111 is a circuit board, the cross-sectional shape of the receiving space 1141 is the shape of the circuit board. When the material 20 carried by the loading unit 111 is a cable, the cross-sectional shape of the receiving space 1141 is the shape of the cable. The loading unit 111 and the material 20 carried by the loading unit 111 are both located within the receiving space 1141. It should be understood that the material 20 and the loading unit 111 are vertically stacked within the receiving space 1141.

[0096] In an embodiment of the present application, the loading mechanism 110 also includes a limiter 114, which can limit the posture of the material 20 carried by the loading unit 111 through the accommodating space 1141 to prevent the posture of the material 20 from changing. When the lifting unit 112 drives the loading unit 111 to rise according to the lifting signal, the loading unit 111 carries the material 20 and rises along the limiter 114, ensuring that the material 20 can rise along the set direction. Due to the limitation of the accommodating space 1141, when the loading unit 111 carries the material 20 to rise, the posture of the material 20 will not change. Therefore, after the robotic arm 12 absorbs the material 20, it can ensure that the material 20 is in the correct posture to prevent welding errors.

[0097] In one possible implementation, Figure 10 The lifting unit 112 structure includes a motor 1121, a screw 1122, a slider 1123, a connecting unit 1124 and a control unit 1125. Figure 10 The left side of the figure shows a front view of the lifting unit 112, Figure 10 The right side figure in FIG shows a side cross-sectional view of the lifting unit 112 .

[0098] like Figure 10As shown, motor 1121 is connected to screw 1122. Motor 1121 can be a stepper motor, servo motor, or AC / DC motor. Motor 1121 is electrically connected to control unit 1125. Control unit 1125 can control motor 1121 to provide rotational power to screw 1122 based on a lifting signal, thereby driving screw 1122 to rotate. In one example, control unit 1125 can be a PLC. Screw 1122 and slider 1123 are connected by threads. When screw 1122 rotates under the drive of motor 1121, the threads cause slider 1123 to slide along screw 1122. Connecting unit 1124 is connected to slider 1123 and loading unit 111 respectively. When slider 1123 slides along screw 1122, it drives connecting unit 1124 to move, which in turn drives loading unit 111 to rise or fall.

[0099] In the embodiment of the present application, the lifting unit 112 includes a motor 1121, a screw 1122, a slider 1123, a connecting unit 1124, and a control unit 1125. The control unit 1125 can control the motor 1121 to drive the screw 1122 to rotate based on the lifting signal. The rotation of the screw 1122 can drive the slider 1123 to move along the screw 1122, thereby driving the loading unit 111 to rise through the connecting unit 1124. In this way, the loading unit 111 can be driven to rise based on the lifting signal, so that the top material reaches the target position, ensuring that the robot arm 12 can pick up the material 20 from the loading unit 111, and preventing the robot arm 12 from being unable to pick up the material 20 due to the low height of the material 20.
