Description

Technical Field

[0001] This invention belongs to the field of automation equipment technology and relates to a lead weight production device. Background Technology

[0002] A sinker is an essential auxiliary fishing tackle in a fishing rig. When casting a long distance, the angler uses its weight to throw the hook and bait into the fishing spot ahead. After entering the water, its weight helps to balance the rig. When a fish bites, the weight of the sinker helps to pierce the fish's lip, hooking it.

[0003] Currently, lead weight production relies either on manual rolling or automated lead rolling machines. While these methods meet production needs, they have several shortcomings. Manual rolling inevitably involves prolonged contact with lead strips, which can negatively impact worker health if safety precautions are insufficient. Furthermore, manual rolling is only suitable for small-batch production and has low efficiency. While existing automated lead rolling machines have partially met the need for automated lead weight production, their stability remains insufficient, resulting in a high defect rate. Manual sorting and selection are still necessary. Additionally, the post-processing steps (heating, cooling, dehydration, polishing, separation) in lead weight production are relatively independent and not interconnected. Each lead weight is manually moved and the corresponding equipment is activated to complete the process. This manual handling is laborious, involves frequent contact with lead, and creates a less than ideal production environment. Summary of the Invention

[0015] In summary, the advantages of this invention are:

[0016] This invention integrates and connects a lead coiling machine, sorting device, drying tunnel device, winding device, drying device, material storage device, polishing and separation device, and finished product collection device to automate the entire process of lead weight production, from lead coiling, sorting, heating, cooling, dehydration, polishing, separation, to finished product collection. This reduces manual intervention in each process and the overall manual allocation of the production line, alleviates physical exertion in the handling process, improves the production efficiency of lead weights, enables mass production of lead weights, and reduces the defect rate caused by manual intervention. At the same time, the control system automatically controls each process, accurately and standardizes the operation process of each process, and effectively improves the yield rate.

[0017] This invention uses a guide groove on a front vibrating plate to initially remove defective lead weights, then transports lead weights with acceptable shapes to a sorting device for initial sorting. Simultaneously, the sorting device implements a detection algorithm that identifies the images of the screening field of view captured by a vision camera and the shape of the lead weights in the images. The identification results are fed back to the main controller, which compares and determines whether the shape of the current lead weight is acceptable, thus achieving automatic and accurate sorting of lead weights based on their shape.

[0018] This invention divides the upper drying tunnel into a front chamber, a middle chamber, and a rear chamber, and controls the temperature of each chamber individually. The main controller keeps the temperature at each location in the drying chamber at a relatively stable value, thereby improving the heating uniformity of the conduit of the semi-finished lead weights and reducing the defect rate of the lead weights.

[0051] like Figure 1-17 As shown, a lead weight production apparatus includes a lead coiling machine 1, a feeding conveyor line 21, a front vibrating plate 22, a sorting device 3, a drying tunnel device 4, a winding device 5, a drying device 6, a storage device 7, a polishing and separating device 8, a finished product collection device 9, and a control system, which are arranged in sequence. The control system includes a main controller, and the lead coiling machine 1, the feeding conveyor line 21, the front vibrating plate 22, the sorting device 3, the drying tunnel device 4, the winding device 5, the drying device 6, the storage device 7, the polishing and separating device 8, and the finished product collection device 9 are respectively connected to the main controller.

[0052] The lead winding machine 1 includes a lead winding machine platform 13, a lead strip device 10, a lead feeding device 11, a feeding device 12, a tube cutting device 18, a lead winding table 14, a guide needle device 15, a lead winding device 16, and a pressing and cutting device 17. The lead winding machine platform 13 is set up as an installation platform. The lead strip device 10, the lead feeding device 11, the feeding device 12, the tube cutting device 18, the lead winding table 14, the guide needle device 15, the lead winding device 16, and the pressing and cutting device 17 are arranged on the lead winding machine platform 13. The lead strip device 10, the lead feeding device 11, the pressing and cutting device 17, the lead winding table 14, and the lead winding device 16 are distributed sequentially along the y-direction and are arranged on the same straight line. The feeding device 12, the tube cutting device 18, and the lead winding table 14 are distributed sequentially along the x-direction and are arranged on the same straight line.

[0053] The lead strip device 10 includes a lead strip reel 101, a lead strip guide frame 103, a lead strip support frame 104, and a mechanism fixing frame 105. The lead strip reel 101 is wound with lead strips 102. The lead strip guide frame 103 and the lead strip support frame 104 are fixed on the mechanism fixing frame 105. The mechanism fixing frame 105 is fixed on the lead winding machine 13. The lead strip guide frame 103 is located between the lead strip support frame 104 and the lead strip reel 101. The lead strip 102 extends to the lead feeding device 11 after being guided by the lead strip guide frame 103 and supported by the lead strip support frame 104.

[0054] The lead feeding device 11 includes a front lead feeding mechanism, a rear lead feeding mechanism, and a base plate mechanism. The front lead feeding mechanism includes a front feeding motor 110, a front feeding cylinder 111, and a front feeding plate 112. The front feeding motor 110 and the front feeding cylinder 111 are fixedly mounted on the front feeding plate 112. The front feeding plate 112 is slidably connected to the base plate mechanism. Specifically, the base plate mechanism includes a base plate 119, a bottom slider 1191, and a bottom slide rail 1192. The base plate 119 is fixedly mounted on the lead winding machine 13, and the bottom slide rail 1192 is fixedly mounted on the base plate 119. Preferably, two sets of bottom slide rails 1192 are provided. The length direction of the bottom slide rail 1192 is consistent with the movement direction of the lead strip 102. The bottom slider 1191 is movably mounted on the bottom slide rail 1192. The front feeding plate 112 is fixedly connected to the bottom slider 1191. The front feeding plate 112 and the base plate mechanism are slidably connected through the above structure.

[0055] The front feeding plate 112 is fixedly provided with a concave front feeding groove 1120. The lead strip 102 is located in the front feeding groove 1120. The output end of the front feeding cylinder 111 is fixedly provided with a front pressure plate 1110. The front pressure plate 1110 is located above the front feeding groove 1120. When the front feeding cylinder 111 is activated, the front pressure plate 1110 moves downward. The lead strip 102 is pressed against the front feeding plate 112 by the front pressure plate 1110, thereby realizing the movement of the lead strip 102.

[0056] The front feed motor 110 is used to drive the front lead feeding mechanism to move. Specifically, the front feed motor 110 is fixed on the front feed plate 112, the output shaft of the front feed motor 110 is fixed with the front feed main gear 1171, and the base plate 119 is fixed with the front feed rack 1172. The front feed main gear 1171 and the front feed rack 1172 are meshed and connected. When the front feed motor 110 is started, the meshing action of the front feed main gear 1171 and the front feed rack 1172 drives the front feed plate 112 to slide along the base plate mechanism.

[0057] The rear lead feeding mechanism includes a rear feeding motor 113, a rear feeding cylinder 114, and a rear feeding plate 115. The rear feeding motor 113 and the rear feeding cylinder 114 are fixedly mounted on the rear feeding plate 115. The rear feeding plate 115 is fixedly connected to the bottom slider 1191. The rear feeding plate 115 is slidably connected to the bottom plate mechanism through the above structure.

[0058] The rear feeding plate 115 is fixedly provided with a concave rear feeding groove 1150. The lead strip 102 is located in the rear feeding groove 1150. The front feeding groove 1120 and the rear feeding groove 1150 are opposite each other and collinear. The output end of the rear feeding cylinder 114 is fixedly provided with a rear pressure plate 1140. The rear pressure plate 1140 is located above the rear feeding groove 1150. When the rear feeding cylinder 114 is activated, the rear pressure plate 1140 moves downward, and the lead strip 102 is pressed against the rear feeding plate 115 by the rear pressure plate 1140, thereby realizing the movement of the lead strip 102.

[0059] A lead feeding linkage mechanism is also provided between the front lead feeding mechanism and the rear lead feeding mechanism to achieve linkage between the two mechanisms. Specifically, the lead feeding linkage mechanism includes a lead feeding connecting rod 1161, a lead feeding long rod 1162, and a linkage fixing frame 1163. The lead feeding connecting rod 1161 includes a fixed end and a movable end. The fixed end is fixedly connected to the output shaft of the rear feed motor 113, and the movable end is connected to one end of the lead feeding long rod 1162. The other end of the lead feeding long rod 1162 is connected to the linkage fixing frame 1163, which is fixedly mounted on the front feed mechanism. The distance between the fixed end and the moving end of the lead feeding rod 1161 on plate 112 controls the travel of the lead feeding rod 1162, thereby controlling the cutting length of the lead strip. The travel of the lead feeding rod 1162 is less than the distance between the front feeding motor 110 and the rear feeding motor 113. When the rear feeding motor 113 starts, the lead feeding rod 1161 rotates, driving the lead feeding rod 1162 to move. The front lead feeding mechanism remains fixed, and the movement of the lead feeding rod 1162 causes the rear feeding plate 115 to slide along the base plate mechanism, thereby moving the lead strip from the first set position to the second set position.

[0060] During the implementation of the lead feeding device 11, the lead strip 102 is located in the front feeding trough 1120 and the rear feeding trough 1150. The front feeding cylinder 111 and the rear feeding cylinder 114 are started to press the lead strip 102 into the front feeding trough 1120 and the rear feeding trough 1150. The front feeding motor 110 is started, driving the front feeding plate 112 and the rear feeding plate 115 to move towards the cutting device 17, thereby driving the lead strip 102 to move to the first set position, i.e., the cutting position, completing the initial feeding step of the lead strip 102. After that, the front feeding motor 110 stops running, the front feeding cylinder 111 is reset, and the rear feeding motor 113 is started, driving the lead strip 102 to move to the second set position, completing the final feeding step of the lead strip 102. The distance between the first set position and the second set position is the cutting length of the lead strip.

[0061] The pressing and cutting device 17 includes a pressing and cutting frame 170, a lead pressing mechanism, and a lead cutting mechanism. The pressing and cutting frame is fixed on the lead winding machine table 13. The lead pressing mechanism and the lead cutting mechanism are respectively fixed on the lead winding machine table 13. The lead pressing mechanism includes a lead pressing frame 172, a lead pressing cylinder 171, a lead pressing slide plate 173, and a lead pressing block 174. The lead pressing frame 172 is fixed on the pressing and cutting frame. The lead pressing slide plate 173 is fixed on the output shaft of the lead pressing cylinder 171, and the lead pressing slide plate 173 is slidably connected to the lead pressing frame 172. The lead pressing block 174 is set on the lower end face of the lead pressing slide plate 173. When the lead pressing cylinder 171 is started, it drives the lead pressing slide plate 173 to move down, so that the lead pressing block 174 presses the lead strip 102 onto the lead winding table 14, preventing the end of the lead strip 102 away from the cut from lifting up when the lead cutting mechanism cuts the material.

[0062] The lead cutting mechanism includes a lead cutting frame 176, a lead cutting cylinder 175, a lead cutting slide plate 177, a lead cutting pressure block 178, and a lead cutting blade 179. The lead cutting frame 176 is fixed to the pressure cutting frame 170. The lead cutting slide plate 177 is fixed to the output shaft of the lead cutting cylinder 175, and the lead cutting slide plate 177 is slidably connected to the lead cutting frame 176. The pressure block 174 is set on the lower end face of the pressure slide plate 173. The lead cutting pressure block 178 and the lead cutting blade 179 are respectively fixed on the lower end face of the lead cutting slide plate 177. A cut 141 is provided on the lead winding table 14. The cut 141 is opposite to the lead cutting blade 179. When cutting, the pressure block 178 pre-presses the material to prevent the cut end of the lead cutting blade 179 from bending downward under the action of the lead cutting blade 179, which would affect the subsequent lead winding efficiency and the defect rate.

[0063] During the operation of the pressing and cutting device 17, the lead feeding device 11 moves the lead strip 102 to the second set position. At this time, the pressing cylinder 171 is activated, and the pressing block 174 presses the lead strip 102 onto the lead winding table 14. At the same time, the cutting cylinder 175 is activated, and the cutting block 178 presses the lead strip 102 onto the lead winding table 14. The cutting cylinder 175 continues to operate, and the cutting blade 179 inserts into the cutting opening 141 to cut the lead strip 102. The pressing block 174 and the cutting block 178 are located at both ends of the cut lead strip 102 to ensure the flatness of the lead strip 102, which facilitates subsequent lead winding and effectively reduces the defect rate of lead weights.

[0064] The feeding device 12 includes a material tray 121 and a feeding mechanism. The material tray 121 is provided with a guide tube 120. The guide tube 120 is driven by the feeding mechanism to move to the lead coiling table 14. The material tray 121 is fixed to the lead coiling machine table 13 by a material tray fixing frame 122. The feeding mechanism includes a guide tube motor 126, a limiting wheel 129, a swing arm 124, and a fixing frame 123. The guide tube motor 126 is fixed to the lower plate 130, the lower plate 130 is fixed to the lead coiling machine table 13, and the lead coiling table 14 is fixed to the lower plate 130. The output shaft of 126 is fixedly equipped with a feeding main gear 127. One end of the swing arm 124 is connected to the fixed frame 123, and the other end is connected to the limiting wheel 129. The limiting wheel 129 is located above the feeding main gear 127. The guide tube 120 is fastened between the limiting wheel 129 and the feeding main gear 127. When the guide tube motor 126 starts, it drives the feeding main gear 127 to rotate, which in turn drives the guide tube 120 located between the feeding main gear 127 and the limiting wheel 129 to move forward, thereby realizing the conveying of the guide tube 120.

[0065] The feeding device 12 also includes a feeding spring 125. One end of the feeding spring 125 is connected to the swing arm 124, and the other end is connected to the lower plate 130 through a fixing device. The feeding spring 125 ensures that the limiting wheel 129 and the feeding main gear 127 maintain a relatively stable gap during the transportation of the guide tube 120, so as to realize the continuous and stable conveying of the guide tube 120.

[0066] The feeding device 12 also includes a guide tube 128, which is disposed between the material tray 121 and the lead winding table 14. The guide tube 128 is provided with a feeding hole, and the guide tube 120 is located at the feeding hole and moves along the feeding hole, thereby restricting the movement direction of the guide tube 120 and preventing problems such as deviation in the guide tube 120 that could lead to subsequent cutting and reduce the lead winding effect. The guide tube 128 is provided with a cavity at the position of the feeding main gear 127, and the feeding main gear 127 is located in the cavity to realize the conveying of the guide tube 120.

[0067] The pipe cutting device 18 includes a pipe cutting lateral movement mechanism 181, a pipe cutting longitudinal movement mechanism 182, a pipe cutting plate 183, and a pipe cutting blade 184. The pipe cutting blade 184 is located between the feeding device 12 and the lead winding table 14 and is used for cutting the guide tube 120. The pipe cutting blade 184 is fixed at one end of the pipe cutting plate 183, and the other end of the pipe cutting plate 183 is connected to the pipe cutting lateral movement mechanism 181. The pipe cutting lateral movement mechanism 181 is connected to the pipe cutting longitudinal movement mechanism 182, and the pipe cutting longitudinal movement mechanism 182 is fixedly connected to the lead winding machine table 13. When the pipe cutting lateral movement mechanism 181 is activated, it drives the pipe cutting plate 183 to move laterally, controlling the distance between the pipe cutting blade 184 and the lead winding table 14, thereby controlling the cutting length of the guide tube. When the pipe cutting longitudinal movement mechanism 182 is activated, it drives the pipe cutting lateral movement mechanism 181 and the pipe cutting blade 184 to move up or down synchronously to cut the guide tube 120.

[0068] The needle guide device 15 includes a needle guide motor 151, a needle guide holder 152, a needle guide moving block 153, and a needle 154. The needle guide holder 152 and the needle guide motor 151 are fixedly mounted on the lower plate 130. The output shaft of the needle guide motor 151 passes through the needle guide holder 152 and is rotatably connected to the needle guide holder 152. The needle guide moving block 153 is disposed on the output shaft of the needle guide motor 151 and is slidably connected to the needle guide holder 152. The needle 154 is fixedly mounted on the needle guide moving block 153 and follows the needle guide moving block 154. 3. Movement: In the vertical direction, i.e., the z-direction in the figure, the lead strip 102 is located above the lead winding table 14, and the guide needle 154 is located above the lead strip 102. In the horizontal direction, i.e., the x-direction in the figure, the guide needle 154 is opposite to the guide tube 120. When in working state, the guide needle 154 and the guide tube 120 can abut against each other. The guide needle motor 151 is started, causing the output shaft of the guide needle motor 151 to rotate. The rotation of the output shaft of the guide needle motor 151 drives the guide needle moving block 153 to slide, thereby driving the guide needle 154 to move.

[0069] The lead winding device 16 includes a lead bending mechanism 160, a forming mechanism 161, and a lead winding mechanism 162. The lead bending mechanism 160 includes a lead bending cylinder 1601. The output shaft of the lead bending cylinder 1601 is connected to a lead bending fixing plate 1603. A lead bending rack 1602 is fixed on the lower end face of the lead bending fixing plate 1603. A lead bending fixing frame 1604 is fixed on the lower plate 130. The lead bending fixing plate 1603 and the lead bending fixing frame 1604 are slidably connected. After the lead bending cylinder 1601 is started, it drives the lead bending fixing plate 1603 to slide, which in turn drives the lead bending rack 1602 to slide.

[0070] The lead-folding mechanism 160 also includes a lead-folding mounting bracket 1605, which is fixedly mounted on the lower plate 130. A rotating rod 1606 is rotatably mounted inside the lead-folding mounting bracket 1605. A guide pin 154 passes through the rotating rod 1606 and is movably connected to it. The guide pin 154 and the rotating rod 1606 move independently. A lead-folding gear 1607 is fixedly mounted at one end of the rotating rod 1606, and a folding plate 1608 is fixedly mounted at the other end of the rotating rod 1606. The lead-folding gear 1607 and the lead-folding rack 1608 are connected. 02 Engaging connection, the folding plate 1608 has a flat surface. When the lead strip 102 is fed, the flat surface of the folding plate 1608 is parallel to the lead winding table 14. The lead feeding device 11 moves the lead strip 102 to the flat surface of the folding plate 1608, that is, the second set position, so that the lead strip 102 is placed on the flat surface of the folding plate 1608. The guide tube 120 is located above the lead strip 102. The lead folding mechanism 160 operates to control the folding plate 1608 to flip, thereby pre-folding the lead strip 102 located on the flat surface of the folding plate 1608.

[0071] The forming mechanism includes a forming frame 1612, a forming cylinder 1611, and a forming slide plate 1613. The forming frame 1612 is fixed to the cutting frame, and the forming slide plate 1613 is fixed to the output shaft of the forming cylinder 1611. The forming slide plate 1613 is slidably connected to the forming frame 1612. The lower end of the forming slide plate 1613 is fixedly provided with a forming groove 1614. The forming groove 1614 presses the pre-folded lead strip 102 tightly and wraps it in the guide tube 120 to realize the forming process, which facilitates the subsequent lead winding process of the lead winding mechanism 162.

[0072] The lead winding mechanism 162 includes a pressure motor 1623, a pressure cylinder 1624, a lead winding frame 1620, and a lead pressing seat 1626. The lead winding frame 1620 is fixedly mounted on the lead winding machine base 13. The pressure motor 1623 is fixedly mounted to the lead winding frame 1620. A lead winding gear 1627 is fixedly mounted on the output shaft of the pressure motor 1623. The lead pressing seat 1626 is rotatably connected to the lead winding frame 1620, and a sliding lead pressing seat 1626 is provided with... A lead winding slide rail 1621 is provided with lead winding racks 1622 and pressure bars 1625 at both ends. The pressure bars 1625 are located above the lead winding table 14. A pressure cylinder 1624 is fixedly installed on the lead winding machine frame 1620. The pressure cylinder 1624 is located above one side of the lead pressing seat 1626, and the pressure cylinder 1624 and the pressure bars 1625 are located on the same side of the lead pressing seat 1626. The lead winding racks 1622 and 1625 are located on the same side of the lead pressing seat 1626. 622 meshes with the lead-winding gear 1627. The pressure motor 1623 starts and drives the lead-winding gear 1627 to rotate, which in turn drives the pressure bar 1625 to move through the movement of the lead-winding slide rail 1621. During the implementation of the lead-winding mechanism 162, the pressure motor 1623 starts and moves the pressure bar 1625 above the formed lead weight. The pressure cylinder 1624 starts and presses the pressure bar 1625 against the formed lead weight. The pressure motor 1623 continues to run, and the linear movement of the pressure bar 1625 causes the formed lead weight to roll and be rolled by the pressure of the pressure bar 1625, thus realizing the lead-winding process of the lead weight. In this embodiment, during the rolling process of the formed lead weight, the diameter gradually increases. At this time, the pressure cylinder 1624 gradually resets so that the pressure bar 1625 and the outer surface of the lead weight always remain in contact but the pressure is not too high, thus achieving the purpose of automatic lead winding.

[0073] The lead coiling machine 13 is provided with a discharge port 131 and a discharge plate 132. The discharge port 1301 is located at one end of the lead coiling table 14 near the lead feeding device 11. The discharge plate 132 is located inside the lead coiling machine 13. The discharge plate 132 has an inclined structure. The feed end of the discharge plate 132 is located below the discharge port 131, and the discharge end of the discharge plate 132 is located outside the lead coiling machine 13 and above the feed conveyor line 21. The lead weight falls from the discharge port 131 into the discharge end. Under the action of gravity, the lead weight moves to the discharge end and falls into the feed conveyor line 21 through the discharge end.

[0074] During the operation of the lead coiling machine 1, the lead feeding device 11 moves the lead strip to the second set position. The lead pressing mechanism and the lead cutting mechanism start synchronously. The lead pressing block 174 and the lead cutting block 178 press the lead strip onto the lead coiling table 14 respectively. After the lead cutting blade 179 cuts the lead strip, the front feeding cylinder 111 starts, the rear feeding cylinder 114 resets, the rear feeding motor 113 reverses and resets, and the front feeding motor 110 reverses and resets, driving the lead strip to move in the opposite direction to prepare for the next lead feeding step. When the lead strip is in the second set position, the guide needle motor 151 starts, driving the guide needle 154 to move forward. The material handling device moves in the direction of movement until the guide needle 154 abuts against the end face of the guide tube 120. At this time, the guide tube motor 126 starts, and the guide needle motor 151 runs in the opposite direction. With the guide needle 154 always abutting against the guide tube 120, the guide tube 120 gradually moves until it is above the lead strip 102. At this time, the lead folding mechanism 160 operates, and the lead strip 102 is pre-folded, i.e., initially folded, under the action of the folding plate 1608. The forming mechanism operates, pressing the pre-folded lead strip 102 tightly and wrapping it around the guide tube 120 to complete the forming process. At this time, the tube cutting device 18 starts to cut the guide tube 120. The guide tube motor... 126 reverses its rotation, causing the cut conduit 120 to retract a certain distance, away from the cutter 184, to prevent deformation of the end of the cut conduit 120 under the downward movement of the cutter 184 when the cutting device 18 resets. After the cutting device 18 resets, the guide needle motor 151 resets, causing the guide needle 154 to disengage from the state of contact with the conduit 120, thereby preventing wear caused by the end of the conduit 120 contacting the guide needle 154 during lead winding. The pressure motor 1623 starts, moving the pressure bar 1625 above the formed lead weight. The pressure cylinder 1624 starts, moving the pressure bar 1625... 25 is pressed against the formed lead weight, the pressing motor 1623 continues to run, the pressing strip 1625 rolls the formed lead weight, when the pressing strip 1625 is about to contact the lead pressing block 174, the lead pressing cylinder 171 resets, the pressing motor 1623 continues to run, when the pressing strip 1625 is about to contact the lead cutting block 178, the lead cutting cylinder 175 resets, the pressing motor 1623 continues to run to complete the lead rolling process, the pressing motor 1623 pushes the lead weight into the discharge port 131 and into the discharge plate 132, under the action of gravity the lead weight falls along the discharge plate 132 into the feeding conveyor line 21.

[0075] Several lead coiling machines 1 are provided. In this embodiment, four sets of lead coiling machines 1 are set up to form a lead coiling machine group. The lead coiling machines 1 are arranged in pairs, and the feeding conveyor line 21 is located between the lead coiling machines 1. The semi-finished lead weights produced by several lead coiling machines 1 fall into the feeding conveyor line 21. The feeding conveyor line 21 is connected to the front vibrating plate 22. The lead weights are conveyed to the front vibrating plate 22 through the feeding conveyor line 21. In this embodiment, the lead coiling machines 1 are controlled by their respective independent controllers. At the same time, corresponding interfaces and protocols are reserved to facilitate the docking with the main controller and the needs of system expansion.

[0076] The front vibratory plate 22 includes a guide groove 221. The width of the guide groove 221 matches the width of the lead weight. The guide groove 221 can initially reject lead weights with irregular shapes, such as lead weights that have not been successfully rolled into lead or products whose tails have not been successfully rolled into lead. Products with excessively defective shapes cannot be conveyed forward along the guide groove 221 and thus fall back to the front vibratory plate 22. Lead weights with acceptable shapes are transported to the sorting device 3 by the guide groove 221 to achieve preliminary sorting. The front vibratory plate 22 achieves the purpose of conveying lead weights one by one, which facilitates the subsequent sorting process.

[0077] The sorting device 3 is located between the front vibrating plate 22 and the drying tunnel device 4. The sorting device 3 includes a sorting frame 31, a vision camera 32, a sorting bar 37, a sorting mechanism, and a defective product collection device. The vision camera 32 and the sorting bar 37 are fixed on the sorting frame 31. The acquisition direction of the vision camera 32 is facing the semi-finished lead weight located in the guide groove 221. There is a gap between the sorting bar 37 and the guide groove 221. The semi-finished lead weight is conveyed sequentially along the guide groove 221 and the sorting bar 37.

[0078] The vision camera acquires images of the selected field of view. The vision camera is connected to the host industrial control computer via Ethernet. The industrial control computer is equipped with a detection algorithm, which identifies the images of the selected field of view acquired by the vision camera and the shape of the plumb bob in the images. The identification results are fed back to the main controller. The main controller has built-in images of qualified plumb bobs and determines whether the current plumb bob's shape is qualified by comparison.

[0079] The sorting mechanism includes a sorting motor 38, a sorting block 36, and a sorting plate 35. The sorting motor 38 is fixed to the sorting frame 31. The output shaft of the sorting motor 38 is fixed to the sorting block 36, which is located between the guide groove and the sorting strip 37. The length of the sorting block 36 is greater than the length of the semi-finished lead weight. The sorting plate 35 is connected to the sorting frame 31, which is located below the sorting block 36. The sorting plate 35 is inclined. The main controller is connected to the sorting motor 38. When the semi-finished lead weight is determined to be a defective lead weight, the main controller controls the sorting motor 38 to start, and the sorting block 36 rotates, causing the semi-finished lead weight on the sorting block 36 to fall onto the sorting plate 35. The semi-finished lead weight falls into the defective product collection device through the sorting plate 35. When the semi-finished lead weight is determined to be a qualified lead weight, the semi-finished lead weight continues to be conveyed. The semi-finished lead weight is conveyed to the drying tunnel device 4 through the sorting strip 37.

[0080] The drying tunnel device 4 includes a heating chamber 41, a ventilation duct 42, a drying tunnel assembly 43, and a drying tunnel conveyor line 44. The heating chamber 41 is connected to the drying tunnel assembly 43 through the ventilation duct 42, and the drying tunnel conveyor line 44 is installed in the drying tunnel assembly 43.

[0081] The heating chamber 41 is equipped with a blower 412, a heating chamber temperature sensor 413, and heating rods (not shown in the figure). The temperature of the heating chamber 41 is controlled in a closed loop by the number of heating rods and the operating speed of the blower 412. The heating chamber temperature sensor 413 detects the temperature of the heating chamber 41 and feeds the detected temperature value back to the main controller. The main controller controls the temperature of the heating chamber 41 within the set range by controlling the operating speed of the blower 412.

[0082] The drying tunnel assembly 43 includes an upper drying tunnel 431 and a lower support base 432. A drying chamber 433 is provided between the upper drying tunnel 431 and the lower support base 432. The drying tunnel conveyor line 44 is set in the drying chamber 433. In this embodiment, the upper drying tunnel 431 includes a front chamber 4311, a middle chamber 4312 and a rear chamber 4313. The design of the front chamber 4311, the middle chamber 4312 and the rear chamber 4313 ensures that the temperature of the upper drying tunnel 431 is uniform in the length direction, so that the temperature of the upper drying tunnel 431 is at a relatively stable value, avoiding the temperature at both ends being too low, which would affect the heating of the guide tube of the semi-finished lead weight and the subsequent guide tube winding process.

[0083] The front chamber 4311, middle chamber 4312, and rear chamber 4313 have the same structure. Taking the front chamber 4311 as an example, the front chamber 4311 has symmetrical air outlet horizontal plates 4312 on both sides, and an air outlet 4313 is formed between the two sets of air outlet horizontal plates 4312. The hot air from the front chamber 4311 flows from the air outlet 4313 to the drying chamber 433. In this embodiment, the air outlet horizontal plate 4312 includes an inclined plate. The inclined plates of the two sets of air outlet horizontal plates 4312 form a V-shape, thereby guiding the flow of hot air. An air outlet temperature sensor 4314 is also provided in the front chamber 4311. The air outlet temperature sensor 4314 is located below the air outlet 4313 and is used to measure the air outlet temperature of the air outlet 4313. The air outlet temperature sensor 4314 feeds back the detected temperature value to the main controller.

[0084] Several drying tunnel temperature sensors 4331 are installed inside the drying chamber 433. The drying tunnel temperature sensors 4331 are used to measure the temperature of the drying chamber 433. The drying tunnel temperature sensors 4331 feed back the detected temperature value to the main controller. In this embodiment, the drying chamber 433 is controlled at 200 degrees.

[0085] The ventilation duct 42 includes an air inlet end connected to the heating chamber 41 and an air outlet end connected to the drying tunnel assembly 43. The air outlet end includes three sets of ventilation pipes, namely a first ventilation pipe 421, a second ventilation pipe 422 and a third ventilation pipe 423. The first ventilation pipe 421 is connected to the front chamber 4311, the second ventilation pipe 422 is connected to the middle chamber 4312, and the third ventilation pipe 423 is connected to the rear chamber 4313. Through the first ventilation pipe 421, the second ventilation pipe 422 and the third ventilation pipe 423, the hot air from the heating chamber 41 is transmitted to the front chamber 4311, the middle chamber 4312 and the rear chamber 4313 respectively, and is transmitted to the drying chamber 433 through the air outlet 4313 to heat the guide tube of the semi-finished lead weight located on the drying tunnel conveyor line 44.

[0086] The drying tunnel device 4 also includes an adjustment mechanism, which controls the airflow of the first ventilation pipe 421, the second ventilation pipe 422, and the third ventilation pipe 423. The adjustment mechanism includes valves 45, which are provided in three sets and are respectively installed in the first ventilation pipe 421, the second ventilation pipe 422, and the third ventilation pipe 423. The valves 45 are communicatively connected to the main controller. The main controller controls the opening and closing degree of each valve 45 according to the set temperature, the temperature value fed back by the heating chamber temperature sensor 413, the temperature value fed back by the drying tunnel temperature sensor 4331, and the temperature value fed back by the air outlet temperature sensor 4314. This controls the airflow of the first ventilation pipe 421, the second ventilation pipe 422, and the third ventilation pipe 423, and keeps the temperature at each position of the drying chamber 433 at a relatively stable temperature value, so as to improve the heating uniformity of the guide tube of the semi-finished lead weight and reduce the defect rate of the lead weight.

[0087] The winding device 5 is connected to the drying tunnel device 4. The winding device 5 includes a cooling water tank 53, which is connected to the drying tunnel conveyor line 44. The cooling water tank 53 contains room temperature or cooling water. The drying tunnel conveyor line 44 drops the heated semi-finished lead weights into the cooling water tank 53, and then cools them with room temperature or cooling water to cool and wind up the guide tubes of the semi-finished lead weights.

[0088] The winding device 5 also includes a water pump 52 and a water storage tank 51. The water storage tank 51 is located on one side of the cooling water tank 53. The water storage tank 51 contains room temperature or cooling water. The water pump 52 is installed in the water storage tank 51. The water storage tank 51 and the cooling water tank 53 are connected by a water pipe. When the water pump 52 is started, it circulates the water storage tank 51 and the cooling water tank 53 to achieve the purpose of controlling the temperature inside the cooling water tank 53.

[0089] The cooling water tank 53 is equipped with a cooling temperature sensor, which is used to detect the ambient temperature or the temperature of the cooling water in the cooling water tank 53. The cooling temperature sensor is connected to the main controller and the temperature value detected by the cooling temperature sensor is fed back to the main controller. The main controller has a built-in temperature threshold. Once the temperature value exceeds the temperature threshold, the main controller controls the water pump 52 to start, so as to reduce the water temperature in the cooling water tank 53.

[0090] The drying device 6 and the winding device 5 are connected. An inclined line 23 is set between the drying device 6 and the winding device 5. The winding weight is transported to the drying device 6 through the inclined line 23 to dry the moisture. In this embodiment, the drying tunnel device 4 and the drying device 6 have the same structure. The difference between the two is that the drying tunnel device 4 is higher than the drying device 6, and the temperature of the drying device 6 is controlled at 80 degrees.

The material storage positioning motor 74 is fixed to the material storage support 71, and the output shaft of the material storage positioning motor 74 is connected to the material storage moving seat 72. When the material storage positioning motor 74 is activated, it drives the material storage moving seat 72 to slide relative to the material storage support 71. The material storage box 73 is movably connected. In the material storage moving seat 72, the material storage tilting cylinder is fixedly installed on the material storage moving seat 72. The output end of the material storage tilting cylinder is connected to the material storage box 73. The material storage tilting cylinder starts to control the tilting of the material storage box 73. In this embodiment, the material storage moving seat 72 has a material storage station and a material discharge station. When the material storage moving seat 72 is in the material storage station, the material storage box 73 is opposite to the drying device 6. The material storage box 73 receives the dried lead weights. When the material storage moving seat 72 is in the material discharge station, the material storage box 73 is connected to the polishing and separation device 8. The material storage box 73 conveys the lead weights to the polishing and separation device 8.

[0092] Preferably, the storage device 7 also includes a weighing sensor located in the storage bin 73, used to detect the weight of the lead weights in the storage bin 73. The weighing sensor is communicatively connected to the main controller, and the weight value detected by the weighing sensor is fed back to the main controller. The main controller has a built-in weight threshold. Once the weight value exceeds the weight threshold, the main controller controls the storage positioning motor 74 to start. When the storage moving seat 72 moves to the discharge station, the main controller controls the storage tilting cylinder to start and transport the lead weights to the polishing and separation device 8. After that, the main controller controls the storage positioning motor 74 and the storage tilting cylinder to reset, preparing for the next storage process.

[0093] The polishing and separation device 8 includes a polishing box 81 and a polishing motor 82. The polishing box 81 is set on the polishing box frame 80.

The area of ​​the mesh holes is larger than the area of ​​the lead weight and smaller than the area of ​​the polishing wood board. The mesh layer 86 separates the polishing wood board and the lead weight. The polishing wood board falls into the mesh layer 86 while the lead weight falls into the separation plate 85 through the mesh holes. The separation plate 85 then transports the lead weight to the second ramp line 24.

[0096] The polishing and separation device 8 also includes a wooden board collection box 87 and a robot arm 88. The wooden board collection box 87 is connected to the separation box 84.

[0101] In other embodiments, the number of front vibratory feeders 22, sorting devices 3, and feed conveyors 21 is configured according to the number of lead coiling machines 1 set at the front end and the subsequent processing efficiency.

[0102] like Figure 18-26 As shown, the present invention also provides a method for producing lead weights, which produces lead weights based on the above-described lead weight production apparatus, and includes the following steps:

[0103] Step 1: One roll of lead from a lead rolling machine;

[0104] Step 1.1: The lead feeding device 11 conveys the lead bar 102 to the second set position;

[0105] Step 1.2: The pressing and cutting device 17 presses and cuts the lead strip 102. The cutting length of the lead strip 102 is a set value. The cutting length is different for lead weight products of different quality specifications. The first end of the cut lead strip 102 to be rolled is located on the plane of the folding plate 1608. The lead strip 102 to be rolled is located on the lead rolling table 14 except for the first end.

[0106] Step 1.3: The guide needle device 15 and the feeding device 12 operate to transport the guide tube 120 above the lead strip 102 to be wound;

[0107] Step 1.4: The lead folding mechanism 160 is activated to pre-fold the first end of the lead strip 102 to be rolled in step 1.3 onto the guide tube 120. The forming mechanism presses the lead strip 102 to be rolled and wraps it around the guide tube 120 to make a pre-formed lead weight. The tube cutting device 18 is activated to cut the guide tube 120 and reset. The guide needle device 15 and the feeding device 12 are reset. The lead rolling mechanism 162 rolls the pre-formed lead weight automatically to make a semi-finished lead weight.

[0108] Step 1.5: The semi-finished lead weight falls into the discharge plate 132 for discharge;

[0109] Step 2: The front vibrating plate 22 performs preliminary screening of semi-finished lead weights;

[0110] The lead coiling machine 1 conveys the semi-finished lead weights to the front vibrating plate 22 through the feeding conveyor line 21. The width of the guide groove 221 of the front vibrating plate 22 matches the width of the lead weights. If the semi-finished lead weights with good shape and conform to the setting of the guide groove 221 are conveyed through the guide groove 221 and step 3 is executed. The defective lead weights that do not meet the requirements are collected in the defective area.

[0111] Step 3: Sorting device 3 screens semi-finished lead weights;

[0112] Step 3.1: Visual camera 32 acquires and filters images of the field of view;

[0113] Step 3.2: Determine whether the semi-finished lead weight has entered the screening field of view. If yes, proceed to step 3.3; otherwise, proceed to step 3.1.

[0114] Step 3.3: Determine if there are any shape defects in the semi-finished lead weights. If so, the semi-finished lead weights are determined to be defective and proceed to step 3.4. If not, the semi-finished lead weights are determined to be excellent. The excellent products are transported to the drying tunnel device 4 and step 4 is executed to complete one screening. Then, step 3.1 is executed to repeat the semi-finished lead weight screening process.

[0115] Step 3.4: Remove defective products. The main controller controls the sorting motor 38 to start, and the sorting block 36 rotates, causing the defective products to fall into the defective product collection device.

[0116] Step 4: The main controller controls the drying chamber to the target temperature, such as 200 degrees Celsius, and the drying tunnel device 4 heats the guide tubes of the lead weights.

[0117] Step 5: The winding device 5 winds up the semi-finished lead weight by cooling the guide tube at room temperature or with cooling water.

[0118] Step 6: Drying device 6 dries the moisture from the rolled-up lead weight;

[0119] Step 7: The dried lead weights are conveyed to the storage device 7, which then conveys them to the polishing box 81. The polishing and separation device 8 polishes the lead weights. After polishing, the polished wooden board and the finished lead weights are separated by the separation box 84. The polished wooden board is collected in the wooden board collection box 87, and the robot arm transfers the polished wooden board to the polishing box 81.

[0120] Step 8: The finished lead weight falls into the vibrating plate 91, and after being counted by the counting sensor 95, it falls into the finished product collection box 94 for collection.

[0121] The mass of the finished lead weight is the sum of the mass of the lead strip and the guide tube. Since the mass of the lead strip is much greater than the mass of the guide tube, the mass of the guide tube is ignored when calculating the mass of the lead weight; the mass of the lead strip is used as the standard. The cross-sectional width of the lead weight is... Gao Wei , length is The density of the lead strip is ρ. After the lead strip is selected, , Since the parameters ρ and ρ are known values, the weight of the lead weight is only related to the cutting length. The cutting length of the lead strip 102 is related to the operating angle of the rear feeding motor 113. To produce lead weight products of different quality specifications, it is only necessary to change the operating angle of the rear feeding motor.

[0122] The formula for calculating the cutting length of lead strip 102 in step 1.2 is:

[0123] The length of the lead feeding rod 1162 in the lead feeding linkage mechanism is set as G, the length of the lead feeding connecting rod 1161 is set as R, and the initial angle of the initial position of the lead feeding connecting rod 1161 relative to the vertical line of the rotation center is set as... The angle of rotation is negative when counterclockwise relative to the perpendicular line from the center of rotation, and positive when clockwise relative to the perpendicular line from the center of rotation. The distance between the initial position of the end of the lead rod 1162 and the projection of its end onto the displacement plane relative to the center of rotation is set as... The target angle of the lead feed rod 1161 relative to the vertical line of the rotation center is set as follows: Let the distance of the projection of the end of the lead rod 1162 at the target position relative to the center of rotation on the displacement plane be denoted as... Let the cutting length of the lead strip be L. The distance between the rotation center of the lead feeding rod 1161 and the initial and target positions of the lead feeding rod 1162 is set as follows: The initial position end and the target position end of the lead-feeding rod 1162 are at... Figure 19 The direction of the middle arrow indicates the known set position, and the rotation angle of the output shaft connected to the rear feed motor 113 is set to... , The reduction ratio of the reducer connecting the motor shaft and output shaft of the rear feed motor 113 is n:1, and the rotation angle of the motor shaft of the rear feed motor 113 is set to... , Therefore, we can obtain the calculation formula (1):

[0124] (1)

[0125] In the calculation formula (1), G, R, and Given the known set values, L can be obtained from formula (1) and The relationship is adjusted according to the required L value in actual production. Value, and then by adjusting Adjust the cutting length of lead strip 102;

[0126] according to , and From the relationship between the plumb bob mass M and the rotation angle of the motor shaft of the rear feed motor 113, we can obtain the relationship between the plumb bob mass M and the rotation angle of the motor shaft. The calculation formula (2):

[0127] (2)

[0128] According to the calculation formula (2), lead sinker products with different quality specifications can be produced by changing the operating angle of the motor shaft of the rear feeding motor 113 after the change.

[0129] The operating method of the guide pin device 15 and the feeding device 12 in step 1.3:

[0130] As Figure 20 shown, the position A1 is the initial position of the guide pin 154, the position A2 is the separation position of the guide pin 154 and the catheter 120, the position A3 is the positioning position of the pipe cutting knife, and the position A4 is the initial position of the catheter 120 and at the same time the contact position of the guide pin 154 and the catheter 120. The guide pin first runs a distance of (C + B + A) from the position A1 to the position A4, and at this time the guide pin contacts the end face of the catheter. After that, the guide pin and the catheter run synchronously a distance of (A + B) from the position A4 to the position A2, and maintain real-time contact during this period.

[0131] The method for judging whether the semi-finished lead sinker enters the screening vision area in step 3.2 includes the following steps:

[0132] Step 3.2.1: The area threshold of the standard semi-finished lead sinker occupying the pixels of the visual camera 32's field of view is set to S0, and the value of S0 is set according to actual needs. In this embodiment, S0 is set to 200;

[0133] Step 3.2.2: The visual camera 32 collects an image of the screening vision area, and this image is set as P1. The grayscale of P1 is obtained to get a grayscale image, and the grayscale image is set as P2;

[0134] Step 3.2.3: According to the threshold segmentation of the grayscale image P2, search for the area S1 where the grayscale value > G1. In this embodiment, the pixels with the grayscale value > G1 in the grayscale image represent the pixels of the lead sinker in the grayscale image. The values of G1 and S1 are set according to actual needs. In this embodiment, G1 is set to 100;

[0135] Step 3.2.4: Judge whether S1 is greater than S0. If so, execute step 3.2.5. If not, it is determined that the semi-finished lead sinker has not entered the screening vision area, and execute step 3.2.2;

[0136] Step 3.2.5: Judge whether there is a lead sinker at the boundary of P2;

[0137] If the grayscale value at the boundary of P2 > G1, it is determined that there is a lead sinker at the boundary of P2, indicating that the lead sinker has not completely entered the screening vision area, then execute step 3.2.2. If the grayscale value at the boundary of P2 < G1, it is determined that there is no lead sinker at the boundary of P2, indicating that the lead sinker has completely entered the screening vision area, identify the defects of the lead sinker in P1, and then execute step 3.3.

[0138] Step 3.3, which determines whether the semi-finished lead weight has shape defects, utilizes image P1 corresponding to the grayscale image P2 from step 3.2, which indicates the lead weight has completely entered the screening field of view. Image P1 is a color image. In this method, the guide tube 120 and the lead strip 102 on the lead weight are different colors to facilitate color acquisition. Preferably, the guide tube 120 is set to blue and the lead strip 102 is gray. The determination method includes the following steps:

[0139] Step 3.3.1: Image P1 is obtained after step 3.2;

[0140] Step 3.3.2: Determine whether gray or blue is detected in image P1. If yes, P1 detects both gray and blue, indicating that the lead weight has a guide tube 120 and a lead strip 102. At this time, proceed to step 3.3.3. If no, it is considered that the lead weight has a defect of missing either the guide tube 120 or the lead strip 102. The lead weight in image P1 is determined to be a defective product, and step 3.4 is executed.

[0141] Step 3.3.3: Use the color extraction algorithm (RGB to Gray) to extract the lead region ROI1, blue region ROI2, and merged region ROI3 of the weight in P1;

[0142] Merged region ROI3 is Figure 26 The area defined by the dashed line;

[0143] Step 3.3.4: Draw the minimum rectangles REC1, REC2, and REC3 based on ROI1, ROI2, and ROI3 respectively;

[0144] Step 3.3.5: Draw the central axes L1, L2, and L3 of the rectangles in the same direction as the long side of REC3, based on the smallest rectangles REC1, REC2, and REC3 respectively;

[0145] Step 3.3.6: Determine whether the straight line angles of L1, L2, and L3 are close to coincide. If so, proceed to step 3.3.7. When the straight line angles of L1, L2, and L3 are close to coincide, the conduit 120 is at the axis of the lead strip 102. If not, it is considered that the lead weight has a defect of misalignment of the conduit 120, and the lead weight in image P1 is determined to be a defective product. Proceed to step 3.4.

[0146] Step 3.3.7: At the two long side boundaries of the smallest rectangle REC1, find lines L4 and L5 in the vertical region ROI1 using the Hough line;

[0147] Step 3.3.8: Determine whether the straight angle and length of L4 and L5 are close. If so, it is considered that the parallelism of the two sides of the long side of the lead bar 102 is good. At this time, proceed to step 3.3.9. If not, it is considered that the lead bar 102 has a defective shape. The lead weight in image P1 is determined to be a defective product. Proceed to step 3.4.

[0148] Step 3.3.9: At the two short side boundaries of the smallest rectangle REC1, find lines L6 and L7 in the vertical region ROI1 using the Hough line;

[0149] Step 3.3.9: Determine whether the straight angle and length of L6 and L7 are close. If so, it is considered that the parallelism of the short sides of the lead strip 102 is good. At this time, proceed to step 3.3.10. If not, it is considered that the lead strip 102 has a defect of strange shape. The lead weight in image P1 is determined to be a defective product. Proceed to step 3.4.

[0150] Step 3.3.10: Determine whether the lengths of L6 and L7 are within the H range. The H range is set according to actual needs. If yes, it is considered that the outer diameter of the plumb bob meets the set requirements and there are no missing or extra rolls. At this time, proceed to step 3.3.11. If no, it is considered that the plumb bob has a defect of missing or extra rolls. The plumb bob in image P1 is determined to be a defective product. Proceed to step 3.4.

[0151] Step 3.3.11: Determine whether ROI2 is two independent regions ROI4 and ROI5. If yes, it is assumed that both sides of the plumb bob have conduits 120. At this time, proceed to step 3.3.12. If no, it is assumed that the plumb bob has a defect of missing conduits. The plumb bob in image P1 is determined to be a defective product. Proceed to step 3.4.

[0152] Step 3.3.12: Calculate the effective lengths of the central axis L2 within the regions of ROI4 and ROI5, which are d1 and d2, respectively;

[0153] Step 3.3.13: Determine whether d1 and d2 are within the T interval. If so, the lead strip is considered to be located in the middle of the guide tube, and the lead weight in image P1 is determined to be a good product. The good product is transported to the drying tunnel device 4, and step 4 is executed to complete one semi-finished lead weight shape defect detection, and wait for the next semi-finished lead weight shape defect detection. If not, the lead weight is considered to have a defect of missing guide tube, and the lead weight in image P1 is determined to be a defective product. Step 3.4 is executed. The range of the T interval is set according to actual needs. In this embodiment, it is 20-50mm.

[0154] Step 4, the method by which the main controller controls the drying chamber at the target temperature, includes the following steps:

[0155] Step 4.1: Set the target temperature of the drying chamber to T0. Assign the target temperature T0 to the target temperature T01 of the heating chamber and the target temperature T02 of the air outlet. When the heating chamber reaches the target temperature T01 and the air outlet reaches the target temperature T02, the drying chamber reaches the target temperature T0. Set the time t0. When the heating chamber reaches the target temperature T01, the drying chamber reaches the target temperature T0 after t0.

[0156] Step 4.2: The actual temperature of the heating chamber detected by the heating chamber temperature sensor 413 is set as T1. The difference between the actual temperature value of the heating chamber and the target temperature of the heating chamber is set as ΔT1, where ΔT1 = |T1 - T01|. The threshold value for the difference between the actual temperature value of the heating chamber and the target temperature of the heating chamber is set as ΔT01. ΔT01 is set according to the actual adjustment accuracy. If the adjustment accuracy is high, ΔT01 is set small, such as 5 degrees. If the adjustment accuracy requirement is not high, ΔT01 is set large, such as 10 degrees. If ΔT1 is not greater than ΔT01, proceed to step 4.3. If ΔT1 is greater than ΔT01, start the heating chamber temperature adjustment program to readjust until ΔT1 is not greater than ΔT01.

[0157] Step 4.3: The actual temperature of the air outlet detected by the air outlet temperature sensor 4314 is set as T2. The difference between the actual temperature of the air outlet and the target temperature of the air outlet is set as ΔT2, where ΔT2 = |T2 - T02|. The threshold value for the difference between the actual temperature of the heating chamber and the target temperature of the air outlet is set as ΔT02. ΔT02 is set according to the actual adjustment accuracy. If the adjustment accuracy is high, ΔT02 is set to a small value, such as 5 degrees. If the adjustment accuracy requirement is not high, ΔT02 is set to a large value, such as 10 degrees. If ΔT2 is not greater than ΔT02, proceed to step 4.4. If ΔT2 is greater than ΔT02, proceed to step 4.5.

[0158] Step 4.4: The drying tunnel temperature sensor 4331 detects the actual temperature values ​​at various locations in the drying chamber as T3n, n=1, 2...n, where n is the number of drying tunnel temperature sensors 4331 in the drying chamber. The difference between T3n and the target temperature T0 of the drying chamber is set as ΔT3n, ΔT3n=|T3n-T0|. The threshold for the difference between the actual temperature value of the drying chamber and the target temperature T0 of the drying chamber is set as ΔT03. ΔT03 is set according to the actual situation. If ΔT3n is not greater than ΔT03, it is considered that the overall temperature of the drying chamber is in a balanced state. At this time, the drying tunnel device 4 heats the guide tube of the plumb bob and executes step 4.2 to continuously ensure the temperature balance. If ΔT3n is greater than ΔT03, the speed of the blower 412 is adjusted and step 4.2 is executed until ΔT3n is not greater than ΔT03.

[0159] Step 4.5: Determine if the temperature adjustment has timed out;

[0160] When the heating chamber reaches the target temperature T01, the timer starts counting. The real-time detection time is set to t1. t1 and t0 are compared. If t1 is not greater than t0, the opening and closing degree of the regulating valve 45 is controlled by the air outlet temperature regulation program, thereby controlling the air intake of the heating chamber until ΔT2 is not greater than ΔT02. If t1 is greater than t0, it is considered that the target temperature T0 of the drying chamber is set too low. The T0 value is increased, relevant parameters are adjusted, and step 4.1 is executed.
