[0054] The following will be described in detail below with reference to the drawings. Figure 1 -Appendix Figure 13 The present application will be described in further detail.

[0055] The embodiments of the present application disclose a hinge straight arm connecting arm full-automatic machine and an assembling method.

[0056] The hinge straight arm connecting arm can also be referred to as a straight arm hinge with a connecting arm, and the specific style is referred to in the drawings Figure 1 It can be applied in doors, windows or other environments in need, and such a hinge needs to assemble dozens of parts when assembled. Due to the large number of types and complex assembly, a large amount of manpower and material resources are consumed, and the assembly or processing efficiency is affected. Therefore, a hinge straight arm connecting arm full-automatic machine of the present application can be used for assembly.

[0057] A hinge straight arm connecting arm full-automatic machine, referring to Figure 2As shown, three sets of automatic machines are sequentially arranged, and a transport station 15 is arranged between adjacent automatic machines to provide transport. The three sets of automatic machines are used for different processing and assembly, and are sequentially and side-by-side arranged, and are respectively a first automatic machine group 1, a second automatic machine group 2, and a third automatic machine group 3. The first automatic machine group 1 and the third automatic machine group 3 process two kinds of hinge straight arm semi-finished products, such as the first automatic machine group 1 installing a forming straight arm and the third automatic machine group 3 installing a forming connecting arm. The two kinds of semi-finished products are transported to the second automatic machine group 2 through the transport station 15, and the second automatic machine group 2 assembles the two kinds of semi-finished products on a hinge to be connected together, thereby forming a complete hinge straight arm connecting arm. This way can shorten the installation process of the hinge straight arm connecting arm, the first automatic machine group 1 and the third automatic machine group 3 are synchronized to install and transported to the second automatic machine group 2 for assembly, thereby accelerating the assembly efficiency, reducing manual participation, and reducing production cost.

[0058] Each set of automatic machines is provided with an independent controller for control.

[0059] Further, the first automatic machine group 1, the second automatic machine group 2, and the third automatic machine group 3 each further include a discharge station 10 that provides detection and discharges unqualified products. The discharge station 10 is provided with an unqualified product discharge structure 101. When the first automatic machine group 1, the second automatic machine group 2, and the third automatic machine group 3 assemble parts, if there is a part missing or missing, the unqualified semi-finished product or finished product can be discharged from the full-automatic machine through the unqualified product discharge structure 101.

[0060] Since the hinge straight arm connecting arm has a large number of parts and a large number of assembly steps, if an error occurs at a certain step, an unqualified semi-finished product is likely to occur, which not only affects subsequent assembly, but also affects the quality of the finished product after assembly. Therefore, the discharge station 10 is used to distinguish qualified products from unqualified products to ensure that the production of unqualified semi-finished products is reduced during processing and assembly. At the same time, when the first automatic machine group 1 and the third automatic machine group 3 form semi-finished products, the discharge station 10 starts to discharge, timely loss prevention, and avoids discharging after the second automatic machine group 2, which consumes too many parts. After being detected and discharged through multiple discharge stations 10, the production of unqualified products can be greatly reduced, the accuracy of screening can be improved, and the discharge station 10 is provided with a detection structure.

[0061] Furthermore, the transport station 15 is equipped with a weighing and detection structure 16 at one end of the first automatic unit 1 or the third automatic unit 3. The qualified semi-finished products left after the unqualified products are discharged from the discharge station 10 are weighed and re-tested through the weighing and detection structure 16. The qualified semi-finished products are transported through the transport station 15 to the second automatic unit 2 to assemble the two types of hinge straight arms. The re-testing effect of the weighing and detection structure 16 is used to realize the secondary detection after the discharge station 10, and the detection method adopts weighing detection to ensure the accuracy of the detection results.

[0062] Specifically, after the parts are assembled into semi-finished products by the first automatic unit 1 and the third automatic unit 3, the unqualified semi-finished products are discharged by the discharge station 10. The qualified semi-finished products are then transported to the second automatic unit 2 by the transport station 15. Before the finished product is assembled, the qualified semi-finished products are re-tested by the weighing detection structure 16. After the semi-finished products are confirmed to be qualified by weighing, they are transported to the second automatic unit 2 by the transport station 15 for finished product assembly. After assembly, the unqualified products after the finished products are assembled are discharged by the discharge station 10 of the second automatic unit 2. This multi-stage inspection and discharge method increases the pass rate of semi-finished and finished product assembly and improves the overall production efficiency by using the three-line synchronous production method.

[0070] The conveying station 15 is provided with the conveying structure 14 at both ends, which is used for conveying the semi-finished product to the conveying station 15 to convey the semi-finished product to the second automatic machine group 2 for assembly.

[0071] The conveying station 15 is provided with the conveying structure 14 at both ends, which is used for conveying the semi-finished product to the conveying station 15 to convey the semi-finished product to the second automatic machine group 2 for assembly.

[0073] The connecting arm sleeving workstation 12 is used for sleeving the spring seat and the connecting arm. The connecting arm sleeving workstation 12 is provided with a connecting arm sleeving structure 121. Referring to Figure 7 As shown, the connecting arm sleeving structure 121 includes a connecting arm sleeving frame 122, a connecting arm sleeving lifting rail 123, a connecting arm sleeving horizontal rail 124, a connecting arm sleeving horizontal cylinder 125, a connecting arm sleeving lifting cylinder 126, and a connecting arm sleeving clamp jaw 127. The connecting arm sleeving lifting rail 123 and the connecting arm sleeving horizontal rail 124 are both provided with sliding blocks. The connecting arm sleeving clamp jaw 127 is slidingly connected with the connecting arm sleeving lifting rail 123 through the sliding blocks and is connected with the connecting arm sleeving lifting cylinder 126. The connecting arm sleeving lifting cylinder 126 is slidingly connected with the connecting arm sleeving horizontal rail 124 through the sliding blocks and is connected with the connecting arm sleeving horizontal cylinder 125. The extension end of the connecting arm sleeving clamp jaw 127 is connected with the connecting arm sleeving lifting cylinder.

[0074] The sleeve connecting arm clamping jaw 127 clamps the connecting arm, and the sleeve connecting arm lifting cylinder 126 and the sleeve connecting arm horizontal cylinder 125 are driven to make the connecting arm liftable and horizontally movable, so that the connecting arm is sleeved with the spring seat.

[0075] After the sleeve connecting arm station 12 is sleeved, the part carrier 9 continues to rotate to the nail penetrating station 5. The nail penetrating station 5 is provided with a nail penetrating structure and a nail guiding structure 55. Since the spring seat is sleeved with the connecting arm, there is no fixed structure, so the anchor nail is penetrated through the hole of the spring seat and the connecting arm through the nail penetrating structure and the nail guiding structure 55. The nail guiding structure 55 is used to guide the anchor nail to the part carrier 9, and the nail penetrating structure clamps and penetrates the anchor nail through the connecting arm and the spring seat. The nail guiding structure 55 is similar to the carrying structure 14 and can be connected with the vibration disc 146. The anchor nail is stored in the vibration disc 146. After the anchor nail is vibrated out, the anchor nail is clamped by the nail guiding structure 55, so that the anchor nail is located at the same axis as the nail penetrating structure.

[0076] Reference Figure 8 As shown, the nail penetrating structure includes a first nail penetrating cylinder 51, a second nail penetrating cylinder 52, a nail penetrating moving rail 53, and a nail clamping jaw 54. The nail penetrating moving rail 53 is provided with a sliding block connected with the first nail penetrating cylinder 51 and the second transmission cylinder. The nail clamping jaw 54 is connected with the sliding block. The sliding block moves along the nail penetrating moving rail 53 through the driving of the first nail penetrating cylinder 51 and the second nail penetrating cylinder 52, so as to drive the nail clamping jaw 54 to move to the part carrier 9 and open the nail clamping jaw 54 to clamp the anchor nail extended through the nail guiding structure 55. Then, the nail clamping jaw 54 is released, the nail clamping jaw 54 is reset, and the part carrier 9 is continuously rotated by the divider rotating structure 4.

[0077] The part carrier 9 continues to rotate to the spin riveting station 6. The spin riveting station 6 is provided with a spin riveting machine. The spin riveting machine is used to spin rivet the anchor nail penetrating through the spring seat and the connecting sleeve, so that the anchor nail rivets the spring seat and the connecting arm together and cannot be separated.

[0078] Then, the part carrier 9 rotates to the magnifying arm station 13. The carrying structure 14 at the magnifying arm station 13 assembles the large arm in the vibration disc 146 to the part carrier 9. In order to improve the stability of the connection, a set of nail penetrating station 5 and spin riveting station 6 can be further arranged to penetrate the nail and rivet again, so that the large arm is stably connected with the assembled spring seat and connecting arm to form a part of semi-finished product. The part carrier 9 rotates to the transportation station 15 of the first automatic machine group 1. The transportation station 15 is provided with the carrying structure 14. The carrying structure 14 carries the semi-finished product to the transportation station 15. The transportation station 15 can adopt a conveying belt. The transportation station 15 transports the semi-finished product to the second automatic machine group 2.

[0079] The first automatic machine group 1 rotates the part carrier 9 by using the separator rotating structure 4, so that the part carrier 9 sequentially passes through each station, thereby realizing the assembly of the parts on the station to the part carrier 9 without manual operation, improving the assembly efficiency and saving the labor cost.

[0080] In some embodiments, the stations of the third automatic machine group 3 are sequentially arranged along the circumference of the separator rotating structure 4 as the alloy sliding block station 31, the connecting rod station 8, the nail penetrating station 5, and the riveting station 6. Taking a single part carrier 9 as an example, the conveying sequence is the alloy sliding block station 31, the vibration disc 146 at the alloy sliding block station 31 transports the alloy sliding block to the outlet end, the carrying mechanism carries the alloy sliding block to the part carrier 9, the part carrier 9 rotates to the connecting rod station 8 following the separator rotating structure 4, the carrying structure 14 at the connecting rod station 8 places the connecting rod on the part carrier 9, and then passes through the nail penetrating station 5 and the riveting station 6, respectively, to penetrate the anchor nail through the connecting rod and the alloy sliding block, and rivet the anchor nail to the connecting rod and the alloy sliding block, and finally rotates to the conveying station 15 connected with the second automatic machine group 2, and the carrying structure 14 carries the riveted connecting rod and alloy sliding block to the conveying station 15 to be transported to the second automatic machine group 2.

[0081] The third automatic machine group 3 is similar to the first automatic machine group 1, both of which rotate the part carrier 9 by using the separator rotating structure 4, so that the part carrier 9 sequentially passes through each station, thereby realizing the assembly of the parts on the station to the part carrier 9 without manual operation, and finally converging to the second automatic machine group 2, both sides are synchronously processed, further improving the assembly efficiency.

[0082] In some embodiments, the nail penetrating station 5 and the riveting station 6 of the second automatic machine group 2 are provided with two groups, that is, two times of nail penetrating and riveting processes are provided to provide multiple times of nail penetrating and riveting effects, so as to combine the first automatic machine group 1 and the third automatic machine group 3 into one.

[0083] In some embodiments, the first automatic machine group 1 also can be provided with two groups of nail penetrating stations 5 and riveting stations 6.

[0084] Furthermore, the workstations of the second automatic unit 2, along the circumference of the separator rotation structure 4, are sequentially as follows: first semi-finished product placement station 21, oiling station 22, spring seat placement station 7, granule placement station 23, granule pressing station 24, second semi-finished product placement station 25, nail insertion station 5, riveting station 6, connecting rod placement station 8, nail insertion station 5, and riveting station 6. Taking a single part carrier 9 as an example, the conveying sequence is the first finished product placement station, which is equipped with a transport structure 14. The transport structure 14 is located at the end of the transport station 15 of the first automatic unit 1. When the transport station 15 of the first automatic unit 1 transports a portion of the semi-finished products to the first semi-finished product placement station 21, the transport structure 14 transports a portion of the semi-finished products to the part carrier 9 of the second automatic unit 2. The part carrier 9 continues to follow the separator rotation structure 4 to rotate to the oiling station 22, which is equipped with an oiling structure.

[0085] Among them, reference Figure 9 As shown, the refueling structure includes a refueling rack 222, a refueling cylinder 223, a metering valve 224, and a refueling nozzle 225. The refueling cylinder 223 is mounted on the refueling rack 222 and connected to the metering valve 224. A connecting hose is provided between the refueling nozzle 225 and the refueling cylinder 223. A refueling lifting cylinder 226 and a refueling lifting rail 227 can also be installed on the refueling rack 222. The refueling nozzle 225 can be slidably connected to the refueling lifting rail 227 and connected to the telescopic end of the refueling lifting cylinder 226. The refueling lifting cylinder 226 drives the refueling nozzle 225 to rise to the top of the parts carrier 9 for metered addition of lubricating oil.

[0086] After lubricating oil is added to the semi-finished product on the parts carrier 9, it rotates to the spring seat placement station 7, and another set of spring seats is added. The process of the spring seats can be referred to the first automatic unit 1, and will not be repeated here. Then it rotates to the granule placement station 23. The conveying structure 14 at the granule placement station 23 picks up the granules from the vibrating plate 146 where the granules are stored and places them at the spring seats placed at the previous station. The parts carrier 9 rotates to the granule pressing station 24. The granule pressing station 24 is equipped with a granule pressing structure 241, which presses the granules into the spring seats.

[0087] Among them, reference Figure 10As shown, the glue particle pressing structure 241 includes a glue particle rack 242, a glue particle lifting rail 243, a glue particle lifting cylinder 247, a glue particle horizontal rail 244, a glue particle horizontal cylinder 245, and a glue particle wedge-shaped plate 246. The glue particle lifting rail 243 is installed on the glue particle rack 242, the glue particle lifting cylinder 247 is installed on the top of the glue particle lifting rail 243, the glue particle horizontal rail 244 is in sliding connection with the glue particle lifting rail 243 and is connected with the extension end of the glue particle lifting cylinder 247, the glue particle horizontal cylinder 245 is connected with the glue particle rack 242, and the glue particle wedge-shaped plate 246 is in sliding connection with the glue particle horizontal rail 244 and is connected with the extension end of the glue particle horizontal cylinder 245. The glue particle lifting cylinder 247 drives the glue particle horizontal rail 244 to lift along the glue particle lifting rail 243 to drive the glue particle wedge-shaped plate 246 to move, and then the glue particle horizontal cylinder 245 drives the glue particle wedge-shaped plate 246 to move along the glue particle horizontal rail 244. During the movement, the wedge-shaped surface of the glue particle wedge-shaped plate 246 is in contact with the glue particle, and the glue particle is pressed into the spring seat under the pushing of the wedge-shaped surface.

[0088] After the glue particle is pressed into the spring seat, the part carrier 9 is rotated to the second half-finished product placing station 25, and the conveying structure 14 conveys another part of the half-finished product transported by the third automatic machine group 3 to the part carrier 9, so that the two parts of the half-finished product are located on the part carrier 9. The part carrier 9 continues to rotate to the nail penetrating station 5 and the riveting station 6 in turn. The nail penetrating station 5 penetrates the two parts of the half-finished product through the anchor nail, and the riveting station 6 rotates the anchor nail to rivet the two parts of the half-finished product, so that the anchor nail assembles the two parts of the half-finished product. Then, the part carrier 9 is rotated to the connecting rod placing station 8, and the assembled two parts of the half-finished product are placed in the connecting rod. After that, the connecting rod is riveted to the two parts of the half-finished product through the anchor nail by the nail penetrating station 5 and the riveting station 6, and the whole hinge straight arm connecting arm assembly is formed.

[0089] In some embodiments, the first automatic machine group 1 corresponds to the divider rotating structure 4 which is divided into 10 equal parts, and each rotation is 36°. That is, the divider rotating structure 4 of the first automatic machine group 1 rotates ten times for one circle, and each rotation is 36 degrees. Therefore, ten stations can be arranged on the divider rotating structure 4 for switching.

[0090] The rotating station corresponding to the second automatic machine group 2 is divided into 16 equal parts, and each rotation is 22.5°. The divider rotating structure 4 of the second automatic machine group 2 rotates 16 times for one circle, and each rotation is 22.5 degrees. Therefore, sixteen stations can be arranged on the divider rotating structure 4 for switching.

[0091] The third automatic machine group 3 corresponds to a rotating station divided into 8 equal parts, each rotating 45 degrees. The divider rotating structure 4 of the third automatic machine group 3 rotates 8 times for one circle, each time rotating 45 degrees. Therefore, eight stations can be provided on the divider rotating structure 4 for switching. Each equal part of the first automatic machine group 1 to the third automatic machine group 3 is provided with a part carrier 9, so that each part carrier 9 rotates to the corresponding station each time to process or assemble the corresponding station, so that the overall automatic machine can quickly process multiple parts.

[0092] In some embodiments, the detection structure provided on the discharging station 10 is a detection sensor (not shown in the figure), which can also be provided on the unqualified product discharging structure 101 to provide qualified detection of the product. The detection sensor can be an optical sensor or a CDD detection camera. The optical sensor or the CDD detection camera is used to detect whether the assembly of the product is qualified, i.e., the detection data is sent to the controller for data comparison to determine whether it is qualified. When an unqualified product appears, the unqualified product discharging structure 101 clamps and transports the unqualified product on the part carrier 9 out of the automatic machine.

[0093] As shown in the reference Figure 11 , the unqualified product discharging structure 101 includes an unqualified product channel 102, an unqualified product clamping jaw 103, an unqualified product horizontal rail 104, an unqualified product lifting rail 105, an unqualified product lifting rod 106, and an unqualified product driving part 107. The unqualified product channel 102 adopts a large frame body, which is placed on the arc-shaped flowing channel. The unqualified horizontal rail is installed at the unqualified channel. The unqualified product lifting rail 105 is slidingly connected with the unqualified horizontal rail. The unqualified product driving part 107 is installed on the unqualified product channel 102 and is connected with the unqualified product lifting rail 105 in a telescopic manner. The unqualified product driving part 107 can adopt a motor. When the motor is adopted, an arc-shaped opening is formed on the unqualified product channel 102. The output end of the motor is connected with a rotating frame, which can rotate along the arc-shaped opening. The rotating frame is hingedly connected with the unqualified product lifting rod 106. The unqualified product lifting rod 106 is slidingly connected with the unqualified product lifting rail 105. The unqualified product clamping jaw 103 is hingedly connected with the unqualified product lifting rod 106. The unqualified product driving part 107 drives the unqualified product lifting rod 106 to ascend or move along the arc-shaped opening, thereby driving the unqualified product clamping jaw 103 to ascend or horizontally move. The unqualified product clamping jaw 103 moves to the part carrier 9 and clamps the unqualified product on the part carrier 9, and then moves to the unqualified product channel 102. After the unqualified product clamping jaw 103 is released, the unqualified product rolls to the recycling point along the unqualified product channel 102. The detection sensor and the unqualified product clamping jaw 103 are provided. If the part on the part carrier 9 is a qualified product, the unqualified product clamping jaw 103 does not move, and the part carrier 9 rotates with the divider rotating structure 4 to the transportation station 15.

[0094] The second automatic machine group 2 is provided with a qualified product discharge structure at the unqualified product discharge structure 101. The qualified product discharge structure is similar to the unqualified product discharge structure 101 and is used to collect qualified products.

[0095] In some embodiments, with reference to Figure 12 and Figure 13 As shown in the figure, the transport station 15 transports the parts to the second automatic machine group 2. The transport station 15 has a tail end and a head end. The tail end is located at one end of the second automatic machine group 2, i.e., the delivery end of the transport station 15. The head end is located at one end of the first automatic machine group 1 or the third automatic machine group 3, i.e., the initial delivery end of the transport station 15. The parts or semi-finished products are transported from the head end to the tail end, i.e., from the initial delivery end to the delivery end. The transport station 15 is provided with a weighing detection structure 16 at the head end, i.e., the weighing detection structure 16 is arranged at the transport station 15 of the first automatic machine group 1 and the third automatic machine group 3. The corresponding carrying structure 14 of the first automatic machine group 1 or the third automatic machine group 3 carries the semi-finished products from the discharge station to the weighing detection structure 16 at the corresponding position of the first automatic machine group 1 or the third automatic machine group 3. The weighing detection structure 16 weighs the semi-finished products assembled by the first automatic machine group 1 or the third automatic machine group 3 to determine whether the weight of the semi-finished products is qualified. If the weight is qualified, the controller can determine that the weight is qualified. Since each automatic machine group is provided with an independent controller, the controller of the corresponding automatic machine group compares the normal semi-finished product weight with the reweighing result. Since the assembly steps and the number of parts of the first automatic machine group 1 and the third automatic machine group 3 are different, the reweighing results of the two are also different. The reweighing results obtained by the corresponding weighing detection structures of the first automatic machine group 1 and the third automatic machine group 3 can be used to determine whether the corresponding semi-finished products are qualified after reweighing.

[0096] The weighing detection structure 16 comprises a weighing support frame 161, a first weighing table 162, a second weighing table 163, a weighing rotating shaft 165 and a turnover motor 166. The weighing support frame 161 can be arranged on both sides of the conveying station 15. The weighing support frame 161 is provided with two groups of weighing bearings in the vertical direction (hidden in the figure). The first weighing table 162 and the second weighing table 163 are both provided with the weighing rotating shaft 165, and are pivotally connected with the weighing bearings in the vertical direction through the weighing rotating shaft 165. The first weighing table 162 is located above the second weighing table 163. The turnover motor 166 is provided with two groups, and is installed on the weighing support frame 161. The driving ends of the two groups of turnover motors 166 are respectively connected with the corresponding weighing rotating shaft 165 of the first weighing table 162 and the corresponding weighing rotating shaft 165 of the second weighing table 163. The weighing rotating shaft 165 can be driven to rotate according to the needs, so as to drive the first weighing table 162 or the second weighing table 163 to rotate. The first weighing table 162 is located above the conveying station 15. When the first weighing table 162 is inclined, the semi-finished product or the part on the first weighing table 162 can fall into the conveying station. The discharge end of the unqualified product discharge structure 101 corresponding to the first automatic machine group 1 and the third automatic machine group 3 is located on the second weighing table 163, so that the second weighing table 163 can receive the semi-finished product or the part of the unqualified product.

[0097] Specifically, the first weighing table 162 and the second weighing table 163 can perform two retests respectively. When the semi-finished product on the first weighing table 162 is detected to be unqualified in weight, the turnover motor 166 drives the weighing rotating shaft 165 to rotate, so that the semi-finished product on the first weighing table 162 slides to the second weighing table 163. The second weighing table 163 retests the semi-finished product. According to the retest result, the turnover motor 166 and the weighing rotating shaft 165 are used to drive the semi-finished product to be inclined again to slide to the recycling position. Through the two retests of the first weighing table 162 and the second weighing table 163, the qualified rate of the semi-finished product assembly is ensured.

[0098] Among them, the weighing sensor and the signal transceiver are arranged on the first weighing table 162 and the second weighing table 163 to detect the weight of the part or the semi-finished product. The weighing data is sent to the controller. The controller compares the weighing data with the semi-finished product preset data to determine whether it is qualified. If it is qualified, an instruction is sent to the turnover motor 166 to make the first weighing table 162 incline to convey the qualified semi-finished product to the conveying station 15. The unqualified product on the second weighing table 163 is also driven by the turnover motor 166 to be inclined and conveyed to the external recycling structure.

[0099] Further, the bottom surface of the first weighing table 162 is provided with a re-measuring camera 164, which can be a CDD camera, for shooting the unqualified product on the second weighing table 163 and sending the re-measuring data to the controller for comparison to ensure the accuracy of detection. The first weighing table 162 is driven by the overturning motor 166, and the re-measuring camera 164 installed on the bottom of the first weighing table 162 tilts with the first weighing table 162, so as to obtain re-measuring data at different shooting angles and heights, thereby avoiding the situation that the re-measuring data is inaccurate due to the shielding of part of the semi-finished product, and further improving the accuracy of detection. The semi-finished product falling onto the second weighing table 163 can also tilt by a certain angle under the premise that it will not slide down, so that the re-measuring camera 164 obtains more angle re-measuring data.

[0100] The first weighing table 162 is driven by the overturning motor 166, and the direction of overturning determines the moving position of the semi-finished product or part. If the weighing is qualified, the first weighing table 162 is overturned to the direction of the conveying station 15 for conveying to the second automatic machine group 2. If the weighing is unqualified, the first weighing table 162 is overturned in the opposite direction, which can tilt the first weighing table 162 in the opposite direction to make the semi-finished product or part slide to the second weighing table 163 below.

[0101] The second weighing table 163 re-measures the semi-finished product or part falling from the first weighing table 162, and the twice weighing ensures the accuracy of detection. The size of the second weighing table 163 can be larger than that of the first weighing table 162, and a fall-preventing guardrail can be arranged at the edge of the second weighing table 163 to ensure the accurate and stable sliding of the semi-finished product. If the re-measuring result is that the weight of the semi-finished product or part is unqualified, the second weighing table 163 is tilted by the overturning motor 166 to the outside collecting structure to recycle the unqualified semi-finished product or part. If the re-measuring result is qualified, the second weighing table 163 is tilted in the opposite direction, and the opposite direction can be provided with a placing platform. The placing platform can be provided with a qualified collecting box for temporary collection. Subsequently, the qualified semi-finished product or part can be manually placed back to the conveying station 15 above, or the conveying range of the conveying structure 14 can be extended to the placing platform, and the semi-finished product or part can be clamped back to the first weighing table 162 by the conveying structure 14, so as to realize the resetting of the semi-finished product or part.

[0102] The specific weight and connection position of each part are recorded in the controller, so that when the weighing data of the unqualified product is transmitted to the controller, the controller compares one by one according to the different weights of each part to determine which station has a problem. If the weights of the parts are the same or similar, the re-measuring camera 164 transmits the re-measuring data to the controller, and the controller compares the weight with the image data transmitted by the re-measuring camera 164. For example, if a part is missing in the image data, the weight data of the part is compared to determine whether the part is missing, so as to determine which station has a problem.

[0103] The weighing detection structure 16 also provides another way, the weighing detection structure 16 can include a weighing support 161, a first weighing table 162, a second weighing table 163 and a re-measuring camera 164, no longer set up the structure for rotation, so that the semi-finished product or part is located on the first weighing table 162 or the second weighing table 163, the semi-finished product or part is carried to the transport structure or the second weighing table 163 by the carrying structure 14 when the weighing detection is completed, the semi-finished product or part can also be carried away from the second weighing table 163 by the carrying structure 14, compared with the way of adopting the rotation and inclination of the feeding, the carrying structure 14 needs to be applied or an additional set of carrying structures 14 is provided, and the effect of providing the semi-finished product or part conveying after weighing detection can also be realized. In this way, the re-measuring camera can also be arranged at the driving end of the carrying structure 14 to realize multi-angle shooting or image data collection.

[0104] The application also includes a hinge straight arm connecting arm assembly method, which applies the hinge straight arm connecting arm full-automatic machine in the above embodiment, and includes the following steps:
