Description

Technical Field

[0001] The invention belongs to the technical field of automation equipment and relates to an automatic production device and method for a lead sinker. Background Art

[0002] A lead sinker is an essential auxiliary tool in any fishing rig. When casting long distances, the angler uses the weight of the lead sinker to toss the hook and bait into the fishing spot ahead. Once in the water, the lead sinker's weight balances the rig. When a fish bites, the weight of the lead sinker acts as a force to penetrate the fish's lips, securing the hook.

[0003] At present, the production of lead sinkers is either done with the help of manual coiling or with an automatic lead coiling machine. Although the above methods can meet production needs, there are still many shortcomings. The manual coiling method will inevitably lead to long-term contact with lead bars. If the production workers lack awareness of protection, it will inevitably affect their health. In addition, the manual coiling method is only suitable for small-batch production and has low production efficiency. The existing automatic lead coiling machine has met the needs of automated production of lead sinkers to a certain extent, but the current machine stability is still insufficient, and the defect rate of finished products is high. Manual picking and sorting are currently required. In addition, the equipment in the relevant links of the post-processing process (heating-cooling-dehydration-polishing-separation) of the current lead sinker production is relatively independent and not connected in series. The lead sinkers are manually carried one by one, and the equipment in the relevant links is started to complete the process. Manual handling is laborious and will often come into contact with lead, and the production environment is relatively unfriendly. Summary of the Invention

[0026] Step 1.4: The lead folding mechanism is activated to pre-fold the head end of the lead strip to be rolled in step 1.3 onto the guide tube. The forming mechanism compresses the lead strip to be rolled and wraps it around the guide tube to produce a formed lead sinker. The tube cutting device is activated to cut the guide tube and reset.

[0027] Step 1.5: The semi-finished lead falls into the discharge plate for discharge.

[0028] In summary, the present invention is beneficial in that:

[0029] 1) The present invention combines a lead coiling machine, a sorting device, an arranging device, a transfer device, a heating and winding device, a flipping device and a finished product collection device and connects them in series, so as to realize the automation process of lead sinkers from lead coiling, sorting, heating, winding, flipping and finished product collection, reduce the manual intervention of each process and the manual ratio of the entire production line, reduce the physical exertion in the handling link, improve the production efficiency of lead sinkers, realize the batch production of lead sinkers, and reduce the defective rate caused by manual intervention. At the same time, each process is automatically controlled by the control system, the operation flow of each process is accurate and standardized, and the yield rate is effectively improved.

[0030] 2) The present invention preliminarily eliminates defective lead sinkers of irregular shapes through the guide groove of the front vibrating disk, and transports the lead sinkers with acceptable appearance through the guide groove to the sorting device to achieve preliminary sorting. At the same time, the sorting device implements a detection algorithm, identifies the appearance of the lead sinkers in the detection area through the detection algorithm, and feeds back the identification results to the main controller. The main controller further screens the appearance of the current lead sinkers by comparison to determine whether they are of good quality, thereby achieving automatic and accurate screening of the appearance of the lead sinkers. At the same time, the recognition algorithm identifies the lead bar information, and feeds back the identified information to the main controller. The main controller performs corresponding actions according to the received information to achieve finished product quality statistics. At the same time, the main controller has a built-in adjustment algorithm. If the detected lead sinker defect rate is mainly due to the problem of catheter length, the main controller issues relevant adjustment instructions to enable the lead winding machine to adapt to the condition-related parameters and correct the defect.

[0031] 3) The present invention evenly distributes the second station of the clamping mechanism, the heating mechanism and the transfer mechanism around the rotation center of the rotating disk. The arrangement box filled with semi-finished lead sinkers is located at the second station. The rotating disk rotates to move the arrangement box to the heating mechanism for heating. After heating, the rotating disk continues to rotate and the arrangement box moves to the transfer mechanism. The transfer mechanism transfers the arrangement box to the flipping mechanism and repeats the above process to realize the uninterrupted heating and winding process of the lead sinkers, thereby reducing the heating and winding time of the lead sinkers and improving the heating and winding efficiency of the lead sinkers.

The lead strip guide frame 103 is 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 feeding device 11 and the lead strip reel 101. The lead strip 102 is guided by the lead strip guide frame 103 and extends to the lead feeding device 11.

[0066] The lead strip device 10 further includes a marking device 104 , which is fixed to a mechanism fixing frame 105 . The marking device 104 is located between the lead feeding device 11 and the lead strip guide frame 103 .

[0067] The marking device 104 is used to mark the lead bar. In this embodiment, the marking device 104 first prints a scale bar on the lead bar. The spacing between the scale bars is preferably 1 mm, and then prints the lead bar information on the scale bar. The lead bar information includes the serial number of the current lead winding machine 1, the weight of the lead sinker, the production date and other related information. The sorting device 3 identifies the lead bar information, and the sorting device 3 feeds back the identified lead bar information to the main controller to provide a basis for subsequent processing statistics and production digitization.

[0068] The lead feeding device 11 includes a front lead feeding mechanism, a rear lead feeding mechanism and a bottom 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 fixed on the front feeding plate 112, and the front feeding plate 112 is slidingly connected to the bottom plate mechanism. Specifically, the bottom plate mechanism includes a bottom plate 119, a bottom slider 1191, and a bottom slide rail 1192. The bottom plate 119 is fixed on the lead winding machine 13, and the bottom slide rail 1192 is fixed on the bottom plate 119. It is preferred to set two sets of bottom slide rails 1192. The length direction of the bottom slide rail 1192 is consistent with the moving direction of the lead bar 102. The bottom slider 1191 is movably set on the bottom slide rail 1192. The front feeding plate 112 is fixedly connected to the bottom slider 1191. The above structure realizes the sliding connection between the front feeding plate 112 and the bottom plate mechanism.

[0069] The front feed plate 112 is fixed with a concave front feed trough 1120, and the lead bar 102 is located in the front feed trough 1120. The output end of the front feed cylinder 111 is fixed with a front pressure plate 1110, and the front pressure plate 1110 is located above the front feed trough 1120. The front feed cylinder 111 is started to move the front pressure plate 1110 downward, and the lead bar 102 is pressed against the front feed plate 112 through the front pressure plate 1110, thereby realizing the movement of the lead bar 102.

[0070] The front feed motor 110 is used to drive the front lead feed mechanism to move. Specifically, the front feed motor 110 is fixed to the front feed plate 112. The output shaft of the front feed motor 110 is fixed with a front feed main gear 1171. The bottom plate 119 is fixed with a front feed rack 1172. The front feed main gear 1171 is meshed and connected with the front feed rack 1172. When the front feed motor 110 is started, the front feed plate 112 is driven to slide along the bottom plate mechanism through the meshing action of the front feed main gear 1171 and the front feed rack 1172.

[0071] The rear lead feeding mechanism includes a rear feed motor 113, a rear feed cylinder 114 and a rear feed plate 115. The rear feed motor 113 and the rear feed cylinder 114 are fixed on the rear feed plate 115. The rear feed plate 115 is fixedly connected to the bottom slider 1191. The above structure realizes the sliding connection between the rear feed plate 115 and the bottom plate mechanism.

[0072] The rear feed plate 115 is fixed with a concave rear feed trough 1150, the lead strip 102 is located in the rear feed trough 1150, the front feed trough 1120 and the rear feed trough 1150 are opposite to each other, and the two are collinear. The output end of the rear feed cylinder 114 is fixed with a rear pressure plate 1140, and the rear pressure plate 1140 is located above the rear feed trough 1150. The rear feed cylinder 114 is started to move the rear pressure plate 1140 downward, and the lead strip 102 is pressed against the rear feed plate 115 by the rear pressure plate 1140, thereby realizing the movement of the lead strip 102.

[0073] A lead feeding linkage mechanism is also provided between the front lead feeding mechanism and the rear lead feeding mechanism, and the linkage between the front lead feeding mechanism and the rear lead feeding mechanism is realized through the lead feeding linkage mechanism. 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 other end of the lead feeding long rod 1162 is connected to the linkage fixing frame 1163. The linkage fixing frame 1163 is fixed to the front lead feeding mechanism. Plate 112, the distance between the fixed end and the movable end of the lead feeding connecting rod 1161 controls the moving stroke of the lead feeding long rod 1162, and thus controls the cutting length of the lead strip. The moving stroke of the lead feeding long rod 1162 is smaller than the distance between the front feeding motor 110 and the rear feeding motor 113. When the rear feeding motor 113 is started, the lead feeding connecting rod 1161 rotates to drive the lead feeding long rod 1162 to move. The front lead feeding mechanism remains in a fixed state, and the movement of the lead feeding long rod 1162 drives the rear feeding plate 115 to slide along the bottom plate mechanism, thereby moving the lead strip from the first set position to the second set position.

[0074] During the implementation of the lead feeding device 11, the lead strip 102 is located in the front feed trough 1120 and the rear feed trough 1150, the front feed cylinder 111 and the rear feed cylinder 114 are started, and the lead strip 102 is pressed tightly in the front feed trough 1120 and the rear feed trough 1150, and the front feed motor 110 is started, driving the front feed plate 112 and the rear feed plate 115 to move toward the pressing and cutting device 17, thereby driving the lead strip 102 to move, and moving the lead strip 102 to the first set position, that is, the cutting position, completing the initial feeding step of the lead strip 102, after which the front feed motor 110 stops running, the front feed cylinder 111 is reset, and the rear feed 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, and the distance between the first set position and the second set position is the cutting length of the lead strip.

[0075] The pressing and cutting device 17 includes a pressing and cutting frame 170, a lead pressing mechanism and a lead cutting mechanism.

The lead pressing frame 172 is fixed on the pressing and cutting frame, the lead pressing slide 173 is fixed on the output shaft of the lead pressing cylinder 171, and the lead pressing slide 173 is slidingly connected to the lead pressing frame 172. The lead pressing block 174 is arranged on the lower end surface of the lead pressing slide 173. When the lead pressing cylinder 171 is started, the lead pressing slide 173 is driven downward so that the lead pressing block 174 presses the lead strip 102 on the lead rolling platform 14 to prevent the lead cutting mechanism from tilting up the end of the lead strip 102 away from the incision when cutting the material.

[0076] The lead cutting mechanism includes a lead cutting frame 176, a lead cutting cylinder 175, a lead cutting slide 177, a lead cutting pressure block 178 and a lead cutting knife 179. The lead cutting frame 176 is fixed on the pressure cutting frame 170, the lead cutting slide 177 is fixed on the output shaft of the lead cutting cylinder 175, and the lead cutting slide 177 is slidingly connected to the lead cutting frame 176. The lead pressing block 174 is arranged on the lower end surface of the lead pressing slide 173, the lead cutting pressure block 178 and the lead cutting knife 179 are respectively fixed on the lower end surface of the lead cutting slide 177, and an incision 141 is arranged on the lead rolling platform 14, and the incision 141 is opposite to the lead cutting knife 179. When cutting, the lead cutting pressure block 178 presses the material in advance to prevent the fracture from bending downward under the action of the lead cutting knife 179 when the lead cutting knife 179 is cutting, thereby affecting the subsequent lead rolling efficiency and defective rate.

[0077] During the implementation 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 lead pressing cylinder 171 is started, and the lead pressing block 174 presses the lead strip 102 on the lead winding platform 14. At the same time, the lead cutting cylinder 175 is started, and the lead cutting block 178 presses the lead strip 102 on the lead winding platform 14. The lead cutting cylinder 175 continues to run, and the lead cutting knife 179 is inserted into the incision 141 to cut the lead strip 102. The lead pressing block 174 and the lead cutting block 178 are located at both ends of the cut lead strip 102 to ensure the flatness of the lead strip 102, which is convenient for subsequent lead winding and effectively reduces the defective rate of the lead sinker.

[0078] 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 rolling platform 14. The material tray 121 is fixed to the lead rolling machine platform 13 through the material tray fixing frame 122. The feeding mechanism includes a guide tube motor 126, a limiting wheel 129, a rocker 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 rolling machine platform 13. The lead rolling platform 14 is fixed to the lower plate 130. The guide tube motor The output shaft of 126 is fixed with a feed main gear 127, one end of the rocker 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 feed main gear 127, and the conduit 120 is fastened between the limiting wheel 129 and the feed main gear 127. When the conduit motor 126 is started, it drives the feed main gear 127 to rotate, and then drives the conduit 120 located between the feed main gear 127 and the limiting wheel 129 to move forward, thereby realizing the transportation of the conduit 120.

During the implementation of the lead winding mechanism 162, the pressing motor 1623 is started to move the pressing bar 1625 to the top of the formed lead sinker, and the pressing cylinder 1624 is started to press the pressing bar 1625 against the formed lead sinker. The pressing motor 1623 continues to run, and the linear motion of the pressing bar 1625 causes the formed lead sinker to roll and be rolled by the pressure of the pressing bar 1625, thereby realizing the lead winding process of the lead sinker. During the rolling process of the formed lead sinker in this embodiment, the diameter gradually increases. At this time, the pressing cylinder 1624 gradually resets so that the pressing bar 1625 and the outer surface of the lead sinker are always kept in contact but the pressure is not too large, thereby realizing the purpose of automatic lead winding.

The material device moves in the direction of the material device until the guide needle 154 and the end face of the catheter 120 are against each other. At this time, the catheter motor 126 is started, and the guide needle motor 151 runs in the reverse direction. The guide needle 154 and the catheter 120 are always in a state of contact. The catheter 120 gradually retreats until it is above the lead strip 102. At this time, the lead folding mechanism 160 is running, and the lead strip 102 is pre-folded or preliminarily folded under the action of the folding plate 1608.

After the tube cutting device 18 is reset, the guide needle motor 151 is reset to make the guide needle 154 break away from the state of contact with the catheter 120, thereby preventing the end of the catheter 120 from contacting the guide needle 154 and causing wear when the lead is rolled. The pressing motor 1623 is started to move the pressing bar 1625 to the top of the formed lead sinker, and the pressing cylinder 1624 is started to press the pressing bar 1625 to the top of the formed lead sinker. 25 is pressed against the formed lead sinker, the pressing motor 1623 continues to run, the pressing bar 1625 rolls the formed lead sinker, when the pressing bar 1625 is about to contact the lead pressing block 174, the lead pressing cylinder 171 is reset, and the pressing motor 1623 continues to run, when the pressing bar 1625 is about to contact the lead cutting block 178, the lead cutting cylinder 175 is reset, and the pressing motor 1623 continues to run to complete the lead rolling process, and the pressing motor 1623 pushes the lead sinker to fall into the discharge port 131 and into the discharge plate 132. Under the action of gravity, the lead sinker falls along the discharge plate 132 into the feed conveyor line 21.

[0089] Several lead winding machines 1 are provided. In the present embodiment, four groups of lead winding machines 1 are provided to form a lead winding machine group. The lead winding machines 1 are arranged in pairs, and the feeding conveyor line 21 is located between the lead winding machines 1. The semi-finished lead sinkers produced by the several lead winding machines 1 all fall into the feeding conveyor line 21, and the feeding conveyor line 21 is connected to the front vibrating disk 22. The lead sinkers are conveyed to the front vibrating disk 22 via the feeding conveyor line 21.

At the same time, corresponding interfaces and protocols are reserved to facilitate docking with the main controller and system expansion needs.

[0090] The front vibration plate 22 includes a guide groove 221. The width of the guide groove 221 matches the width of the lead sinker. The guide groove 221 can preliminarily eliminate lead sinkers with irregular shapes, such as lead sinkers that were not successfully rolled at the beginning, or products whose tails of the lead bars were not successfully rolled. Products with excessively defective shapes cannot be transported forward along the guide groove 221, and thus fall back to the front vibration plate 22. The lead sinkers with acceptable shapes are transported from the guide groove 221 to the sorting device 3 to achieve preliminary sorting. The front vibration plate 22 achieves the purpose of transporting the lead sinkers one by one, which is convenient for subsequent sorting processes.

[0092] The visual camera collects images of the screening field of view. The visual camera is connected to the upper industrial computer via Ethernet. The industrial computer is equipped with a detection algorithm and a recognition algorithm. The detection algorithm recognizes the image of the screening field of view collected by the visual camera and the shape of the lead sinker in the image, and feeds back the recognition result to the main controller. The main controller has a built-in shape of the lead sinker of good quality. The main controller determines whether the current lead sinker shape is good quality by comparison. At the same time, the recognition algorithm recognizes the lead bar information and feeds back the recognized information to the main controller. The main controller performs corresponding actions based on the received information. For example, the main controller realizes the quality statistics of the finished products of the lead winding machine with this serial number based on the recognized lead winding machine serial number and the judgment result of the lead sinker shape. If the defect rate of the lead sinker produced by the lead winding machine with this serial number is too high, an alarm can be triggered and a shutdown signal can be sent to the lead winding machine 1. At the same time, the main controller has a built-in adjustment algorithm. If the detected lead sinker defect rate is mainly due to a problem of missing catheters, such as a problem of too small or too large length, the main controller issues relevant adjustment instructions so that the lead winding machine 1 can adapt to the relevant parameters of the conditions and correct the defect.

The rotation direction of the sorting rotating conveyor belt 34 is perpendicular to the moving direction of the semi-finished lead sinker. The semi-finished lead sinker moves into the cavity and is driven by the sorting rotating conveyor belt 34 to rotate.

[0115] In this embodiment, Figure 16 The front vibration plate, rear vibration plate, cylinders and motors shown are all controlled by the main controller. The main controller can be connected to the operation screen. The various numerical values ​​received by the main controller are displayed through the operation screen. At the same time, the action commands can be output to the main controller through the operation screen. I will not go into details here.

[0116] In this embodiment, Figure 16 The motor, weighing sensor, and heating plate of the feed conveyor line shown are all connected to the main controller through analog modules and Ethernet modules, which will not be described in detail here.

[0117] In this embodiment, Figure 16 The sorting rotary motor, the motor of the transverse movement mechanism, the motor of the longitudinal movement mechanism, the transfer rotary motor, the rotary motor, the motor of the lifting component, the transfer motor, the flip motor, and the counting sensor are connected to the main controller and will not be described in detail here.

[0118] In other embodiments, the number of front vibration plates 22, sorting devices 3 and feed conveyor lines 21 is configured according to the number of lead rolling machines 1 set at the front end and the subsequent processing efficiency.

[0119] like Figure 17-25 As shown, the present invention also provides a method for automatically producing a lead sinker, which is based on the above-mentioned automatic lead sinker production device to produce a lead sinker, comprising the following steps:

[0120] Step 1: Lead rolling machine 1 rolls lead;

[0121] Step 1.0: The marking device prints a scale bar on the lead bar, and prints lead bar information on the scale bar. The lead bar information includes the serial number of the current lead coiling machine 1, the weight of the lead weight, the production date and other related information;

[0122] Step 1.1: The lead feeding device 11 transports the lead strip 102 to a second set position;

[0123] Step 1.2: The pressing and cutting device 17 presses the lead strip 102 and cuts the lead strip 102. The cut length of the lead strip 102 is a set value. The cut lengths of the lead sinkers of different quality specifications are different. The head end of the cut lead strip 102 to be coiled is located on the plane of the folding plate 1608. Except for the head end, the lead strip 102 to be coiled is located on the lead coiling platform 14.

[0124] Step 1.3: The needle guide device 15 and the feeding device 12 operate to transport the catheter 120 to the top of the lead strip 102 to be rolled;

[0125] Step 1.4: The lead folding mechanism 160 is activated to pre-fold the head end of the lead strip 102 to be rolled in step 1.3 onto the conduit 120. The forming mechanism compresses the lead strip 102 to be rolled and wraps it around the conduit 120 to produce a formed lead sinker. The tube cutting device 18 is activated to cut the conduit 120 and reset. The needle guide device 15 and the feeding device 12 are reset. The lead rolling mechanism 162 rolls the formed lead sinker to automatically roll the lead sinker to produce a semi-finished lead sinker.

[0126] Step 1.5: The semi-finished lead falls into the discharge plate 132 for discharge;

[0127] Step 2: The front vibration plate 22 preliminarily screens the semi-finished lead sinkers;

[0128] The lead coiling machine 1 conveys the semi-finished lead sinkers to the front vibrating plate 22 through the feed conveyor line 21. The width of the guide groove 221 of the front vibrating plate 22 matches the width of the lead sinkers. The semi-finished lead sinkers with good appearance and meeting the setting of the guide groove 221 are conveyed through the guide groove 221 and step 3 is executed. The defective lead sinkers that do not meet the requirements are collected in the defective area.

[0129] Step 3: The sorting device 3 screens the semi-finished lead sinkers and identifies the lead bar information;

[0130] Step 3.1: The visual camera 32 collects images of the screening field of view;

[0131] Step 3.2: Determine whether the semi-finished lead sinker enters the screening field of view. If so, proceed to step 3.3; if not, proceed to step 3.1.

[0132] Step 3.3: Determine whether the lead bar information of the semi-finished lead sinker enters the screening field of view. If so, proceed to step 3.5; if not, proceed to step 3.4.

[0133] Step 3.4: The sorting rotating mechanism drives the semi-finished lead sinker to rotate, and executes step 3.3;

[0134] Step 3.5: Identify the lead bar information of the current semi-finished lead sinker;

[0135] Step 3.6: Determine whether the semi-finished lead pendant has any shape defects. If so, the semi-finished lead pendant is determined to be defective and step 3.7 is executed. If not, the semi-finished lead pendant is determined to be good quality. The good quality products are conveyed to the arrangement device 4 and step 5 is executed to complete the first screening. Then, step 3.1 is executed to repeat the semi-finished lead pendant screening and identification process.

[0136] Step 3.7: To remove defective products, the main controller controls the sorting motor 38 to start, and the sorting block 36 rotates, so that the defective products fall into the defective product collection device;

[0137] Step 4: The main controller counts the quality of the finished product of the lead coiling machine;

[0138] Step 4.1: The main controller has built-in defective rate threshold V0 of the lead coiling machine and defective product ratio threshold V1 due to missing tubes. The defective rate threshold V0 and defective product ratio threshold V1 due to missing tubes are set according to actual needs. For example, V0 can be set to 30 and V1 can be set to 50.

[0139] Step 4.2: Identify the serial number X of the lead coiling machine 1 of the semi-finished lead sinker in the image of the screening field of view, where X=1, 2, 3...n, and X is the same as the set number of lead coiling machines 1;

[0140] Step 4.3: According to step 3, the current semi-finished lead sinker is identified as defective or good. Repeat step 3 to obtain the number N of semi-finished lead sinkers, the number N0 of defective products, and the number N1 of defective products with missing guide tubes for the same lead winding machine 1.

[0141] Step 4.4: According to step 4.2, obtain the defective rate V of the semi-finished lead sinker of lead coiling machine 1 with serial number X, where V = N0 / N, and the defective proportion V2 of the defective products due to the missing guide tube, where V2 = N1 / N0;

[0142] Step 4.5: Determine whether V is not less than V0. If so, it is considered that the defect rate of the lead sinkers produced by the lead coiling machine No. X is too high, and the alarm is triggered. The lead coiling machine No. X receives the stop signal and stops. If not, the lead coiling machine No. X continues to execute the production process.

[0143] Step 4.6: Determine whether V2 is not less than V1. If so, the main reason for the defective semi-finished lead weight is the missing guide tube. In this case, proceed to step 4.7. If not, the lead coiling machine 1 of serial number X is waiting for manual inspection.

[0144] Step 4.7: The main controller issues an adjustment instruction to adjust the parameters related to the conditions that the lead winding machine 1 of serial number X can adapt to, correct the defect of the missing conduit, and start the lead winding machine 1 of serial number X after correction.

[0145] Step 5: The good semi-finished lead sinkers fall into the arrangement box 43. When the arrangement box 43 is full, it is transferred to the heating area by the transfer device 5. The heating mechanism heats the sinkers. The transfer mechanism transfers the arrangement box 43 to the turning device. The heated semi-finished lead sinkers are naturally cooled and wound during the transfer process.

[0146] Step 6: The flipping device 7 flips the arrangement box 43, so that the lead pendant falls into the finished product collecting device 9; Step 7: The finished lead pendant falls into the rear vibration plate 91, and the finished lead pendant falls into the finished product collecting box 94 for collection after being counted by the counting sensor 95.

[0147] The mass of the finished lead sinker is the sum of the mass of the lead bar and the mass of the catheter. Since the mass of the lead bar is much greater than that of the catheter, the mass of the catheter is ignored when calculating the mass of the lead sinker, and the mass of the lead bar is used as the standard. The cross-sectional width of the lead sinker is W0, the height is H0, the length is L, and the density of the lead bar is ρ. After the lead bar is selected, the parameters W0, H0 and ρ are known values, so the mass of the lead sinker is only related to the cutting length. The cutting length of the lead bar 102 is related to the operating angle of the rear feeding motor 113. To produce lead sinker products of different quality specifications, it is only necessary to change the operating angle of the rear feeding motor.

[0148] The calculation formula for the cut length of the lead strip 102 in step 1.2 is:

[0149] The length of the lead feeding long rod 1162 of the lead feeding linkage mechanism is set to G, the length of the lead feeding connecting rod 1161 is set to R, and the initial angle of the initial position of the lead feeding connecting rod 1161 relative to the perpendicular line of the rotation center is set to θ0; the angular rotation direction is negative counterclockwise relative to the perpendicular line of the rotation center, and positive clockwise relative to the perpendicular line of the rotation center, the distance of the initial position end of the lead feeding long rod 1162 relative to the rotation center on the displacement plane is set to S0, the target angle of the target position of the lead feeding connecting rod 1161 relative to the perpendicular line of the rotation center is set to θ1, the distance of the target position end of the lead feeding long rod 1162 relative to the rotation center on the displacement plane is set to S1, the cutting length of the lead bar is set to L, L=S1-S0; the distance between the rotation center of the lead feeding connecting rod 1161 and the initial position end and the target position end of the lead feeding long rod 1162 is set to ΔR, and the initial position end and the target position end of the lead feeding long rod 1162 are at Figure 18 The direction of the middle arrow is a known set position. The rotation angle of the output shaft connected to the rear feeding motor 113 is set to θ, θ=θ0-θ1, the reduction ratio of the reducer connected to the motor shaft and the output shaft of the rear feeding motor 113 is n:1, and the operating angle of the motor shaft of the rear feeding motor 113 is set to δ, δ=n×θ, so the calculation formula (1) can be obtained:

[0150] In the calculation formula (1), G, R, ΔR and θ0 are known set values. The relationship between L and δ can be obtained from the calculation formula (1). In actual production, the δ value is adjusted according to the required L value, and then the cutting length of the lead strip 102 is adjusted by adjusting the δ value.

[0151] According to the relationship between δ, θ0 and θ1, the calculation formula (2) for the lead weight M and the motor shaft operating angle δ of the rear feed motor 113 can be obtained:

[0152]

[0153] According to the calculation formula (2), lead sinker products of different quality specifications can be produced by changing the motor shaft running angle of the rear feeding motor 113.

[0154] Operation method of the needle guide device 15 and the feeding device 12 in step 1.3:

[0155] like Figure 19 As shown, position A1 is the initial position of guide needle 154, position A2 is the separation position of guide needle 154 and catheter 120, position A3 is the positioning position of the tube cutter, and position A4 is the initial position of catheter 120 and the contact position of guide needle 154 and catheter 120. The guide needle first moves from position A1 a distance (C+B+A) to position A4, at which point the guide needle and catheter end surfaces contact. Thereafter, the guide needle and catheter simultaneously move from position A4 a distance (A+B) to position A2, maintaining real-time contact during this period.

[0156] The method for determining whether the semi-finished lead sinker enters the screening field of view in step 3.2 includes the following steps:

[0157] Step 3.2.1: The threshold value of the area occupied by the standard semi-finished lead pendant in the visual camera 32 pixels is set to S0. The value of S0 is set according to actual needs. In this embodiment, S0 is set to 200;

[0158] Step 3.2.2: The visual camera 32 collects an image of the screened field of view, which is set as P1. P1 is grayscaled to obtain a grayscale image, which is set as P2.

[0159] Step 3.2.3: Retrieve the area S1 with grayscale value greater than G1 based on the threshold segmentation of the grayscale image P2. In this embodiment, pixels with grayscale value greater than G1 represent the pixels of the plumb bob in the grayscale image. The values ​​of G1 and S1 are set according to actual needs. In this embodiment, G1 is set to 100.

[0160] Step 3.2.4: Determine whether S1 is greater than S0. If so, execute step 3.2.5. If not, determine that the semi-finished lead pendant does not enter the screening field of view, and execute step 3.2.2;

[0161] Step 3.2.5: Determine whether there is a sinker at the P2 boundary;

[0162] If the gray value of the P2 boundary > G1, it is determined that there is a sinker at the P2 boundary, indicating that the sinker has not fully entered the screening vision area, then execute Step 3.2.2. If the gray value of the P2 boundary < G1, it is determined that there is no sinker at the P2 boundary, indicating that the sinker has fully entered the screening vision area, identify the sinker defects in P1, then execute Step 3.3.

[0163] The method for determining whether there are shape defects in the semi-finished sinker shape in Step 3.3 uses the image P1 corresponding to the grayscale image P2 where it has been determined in Step 3.2 that the sinker has fully entered the screening vision area. Image P1 is a color image. In this method, the catheter 120 and the lead bar 102 on the sinker have different colors, which is convenient for color acquisition. Preferably, the catheter 120 is set to blue and the lead bar 102 is gray. The judgment method includes the following steps:

[0164] Step 3.3.1: Obtain image P1 through Step 3.2;

[0165] Step 3.3.2: Determine whether gray or blue is recognized in image P1. If so, and P1 recognizes both gray and blue at the same time, it means that the sinker has the catheter 120 and the lead bar 102. At this time, execute Step 3.3.3. If not, it is considered that there is a defect in the sinker where one of the catheter 120 and the lead bar 102 is missing, determine that the sinker in image P1 is a defective product, and execute Step 3.7;

[0166] Step 3.3.3: Use the color extraction algorithm (RGB to Gray) to extract the lead region ROI 1, the blue region ROI2, and the merged region ROI3 of the sinker in P1;

[0167] The merged region ROI3 is Figure 18 the region formed by the dotted line in

[0168] Step 3.3.4: Draw the minimum rectangles REC1, REC2, and REC3 according to ROI 1, ROI2, and ROI3 respectively;

[0169] Step 3.3.5: Draw the rectangle central axes L1, L2, and L3 in the same direction as the long side of REC3 according to the minimum rectangles REC1, REC2, and REC3 respectively;

[0170] Step 3.3.6: Determine whether the straight line angles of L1, L2, and L3 are close to coincidence. If so, execute Step 3.3.7. When the straight line angles of L1, L2, and L3 are close to coincidence, the catheter 120 is at the axial center position of the lead bar 102. If not, it is considered that there is a defect in the sinker where the catheter 120 is misaligned, determine that the sinker in image P1 is a defective product, and execute Step 3.7;

[0171] Step 3.3.7: At the two long side boundaries of the minimum rectangle REC1, find lines L4 and L5 in the lead region ROI 1 using the Hough lines.

[0172] Step 3.3.8: Determine whether the angles and lengths of the lines L4 and L5 are similar. If so, the parallelism of the long sides of lead bar 102 is considered good, and step 3.3.9 is performed. If not, lead bar 102 is considered to have an odd shape defect, and the lead weight in image P1 is determined to be defective, and step 3.7 is performed.

[0173] Step 3.3.9: At the two short side boundaries of the minimum rectangle REC1, find lines L6 and L7 in the lead region ROI 1 using the Hough lines.

[0174] Step 3.3.9: Determine whether the angles and lengths of the lines L6 and L7 are similar. If so, the parallelism of the short sides of lead bar 102 is considered good, and step 3.3.10 is performed. If not, lead bar 102 is considered to have an odd shape defect, and the lead sinker in image P1 is determined to be defective, and step 3.7 is performed.

[0175] Step 3.3.10: Determine whether the lengths of L6 and L7 are within the range H. The range of H can be set according to actual needs. If so, the outer diameter of the lead pendant is considered to meet the set requirements and there is no under- or over-coil. In this case, proceed to step 3.3.11. If not, the lead pendant is considered to have an under- or over-coil defect. The lead pendant in image P1 is determined to be defective and step 3.7 is executed.

[0176] Step 3.3.11: Determine whether ROI2 is two independent regions ROI4 and ROI5. If so, it is assumed that the lead sinker has catheters 120 on both sides, and step 3.3.12 is executed. If not, it is assumed that the lead sinker has a defect of missing catheters, and the lead sinker in image P1 is determined to be defective, and step 3.7 is executed.

[0177] Step 3.3.12: Calculate the effective lengths of the central axis L2 within ROI4 and ROI5, which are d1 and d2 respectively.

[0178] Step 3.3.13: Determine whether d1 and d2 are within the T interval. If so, it is considered that the lead strip is located in the middle of the catheter, and the lead sinker in image P1 is determined to be a good product. The good product is transported to the arrangement device 4, and step 5 is executed to complete a semi-finished lead sinker appearance defect detection, and wait for the next semi-finished lead sinker appearance defect detection. If not, it is considered that the lead sinker has a defect of missing catheter, and the lead sinker in image P1 is determined to be a defective product, and step 3.7 is executed. The range of the T interval is set according to actual needs, and in this embodiment it is 20-50mm.

[0179] The method for adjusting the parameters related to the conditions for self-adaptation of the lead coiling machine 1 of sequence number X in step 4.7 includes:

[0180] The catheter at the cutoff position of the lead weight identified in step 3 is set to extend more by Δa, and the main controller sends an adjustment command of the lead winding machine 1 with the serial number X to advance the pipe cutting knife by a distance of Δa; the catheter at the cutoff position of the lead weight identified in step 3 is set to extend less by Δc, and the main controller sends an adjustment command of the lead winding machine 1 with the serial number X to control the guide needle to retreat by a distance of Δc and the catheter to advance by a distance of Δc so that the separation position of the two ends is satisfied at the L2 position.

[0181] Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of the present invention.
