Description
Technical Field
[0001] This invention relates to the field of slot commutator manufacturing technology, specifically to a horizontal automatic inserting machine for slot commutators. Background Technology
[0002] The production process of slotted commutators requires the insertion of numerous copper sheets into a plastic shell. This places high demands on the insertion accuracy of the copper sheets and the conveying process of the plastic shell and copper sheets. Currently, there are dedicated insertion machines to complete this process. Most existing insertion machines utilize the weight of the copper sheets and use left and right vertical feed channels and pusher cylinders for symmetrical vertical arrangement. After the copper sheets fill the mandrel, the positioned plastic shell is inserted. The main drawback is that after the copper sheets come out of the vibratory feeder, they pass through a long and winding special feed channel to reach the pusher cavity, where they are pushed into the mandrel slot by a small cylinder. After passing through this special feed channel to reach the pusher cavity, the process is very sensitive to the dimensional tolerances, burrs, deformation, and mixing of the copper sheets. It is impossible to completely prevent abnormalities or defects in cold-headed copper sheets during bagged logistics. Therefore, the production process is frequently interrupted, and it is very difficult to remove abnormal copper sheets. Disassembling the machine to remove them and reassembling them is laborious and time-consuming. For the reasons mentioned above, it is necessary to redevelop the sheet-laying equipment to solve the problems of accurate insertion and stable and smooth conveying of copper sheets and plastic shells. Summary of the Invention
[0003] This invention provides a horizontal automatic chip inserter for slotted commutators, which can solve the problems of easy jamming during the conveying of copper sheets and plastic shells in existing chip inserters, as well as the low accuracy of the insertion and positioning of plastic shells and copper sheets.
[0004] To achieve the above objectives, the present invention provides the following technical solution: a horizontal automatic inserting machine for slotted commutators, comprising a plastic shell feeding vibratory plate and a copper sheet feeding vibratory plate, and a rotating plate vertically disposed between the plastic shell feeding vibratory plate and the copper sheet feeding vibratory plate. The rotating plate is driven to rotate by an indexing motor on its first side. A first station, a second station, and a third station are evenly installed around the circumference near the edge of the rotating plate. Insertion station assemblies are installed in each of the first, second, and third stations. The plastic shell feeding vibratory plate is connected to a plastic shell feeding conveying assembly. One end of the plastic shell feeding conveying assembly matches the first station on the rotating plate. A plastic shell pushing assembly corresponding to the first station is installed on one side of the plastic shell feeding conveying assembly to push the plastic shell in the plastic shell feeding conveying assembly into the first station. A mounting bracket is provided on the second side of the rotating plate. A copper sheet transverse conveying line corresponding to the second station is installed on the mounting bracket. One end of the copper sheet transverse conveying line... The rotating disk is connected to a copper sheet feeding vibratory feeder at one end and to a copper sheet insertion feeding assembly at the other end. A plastic shell indexing rotating assembly is installed on the first side of the rotating disk above the indexing motor. This assembly includes a sheet insertion plug that can extend into the second station to mate with the plastic shell and a drive motor that drives the insertion plug to rotate at the indexing points. Feeding conveyors and unloading push rod assemblies corresponding to the third station are also installed on both sides of the rotating disk. By setting up a rotating disk with three stations, precise insertion and assembly of copper sheets and plastic shells is achieved at the second station. The combination of a transverse copper sheet conveyor line and the copper sheet insertion feeding assembly enables stable and smooth feeding and individual gripping of copper sheets. Simultaneously, the combination of the plastic shell feeding conveyor assembly, the plastic shell pushing assembly, and the plastic shell indexing rotating assembly enables smooth feeding and precise positioning of the plastic shell. Precise indexing rotation is performed during insertion, achieving rapid insertion. This comprehensively solves the problems of easy jamming during copper sheet and plastic shell feeding in existing insertion machines and the low accuracy of insertion and positioning between the plastic shell and copper sheet.
[0005] Preferably, the copper sheet insertion assembly includes a lifting chamber located between the transverse copper sheet conveying line and the second station. The lifting chamber is connected to a vertical slider located below it. The vertical slider is driven to move up and down by a lifting cylinder mounted on a mounting bracket. A first transverse sliding block is mounted on the mounting bracket and slides transversely above the transverse copper sheet conveying line. An inserting rod corresponding to the lifting chamber at the higher position is mounted on the first transverse sliding block. The first transverse sliding block is driven by a first transverse sliding cylinder and uses the inserting rod to push out the copper sheet in the lifting chamber and insert it into the plastic shell in the second station. The lifting chamber can accurately grasp the transversely conveyed copper sheet in the transverse copper sheet conveying line, and the inserting rod can accurately push out the copper sheet in the lifting chamber.
[0006] Preferably, the copper sheet transverse conveying line includes a linear vibrating conveyor and a copper sheet conveying track installed on the upper side of the linear vibrating conveyor. The copper sheet conveying track corresponds to the lifting chamber located at a lower position. A quick-release cover is installed on the upper side of the copper sheet conveying track, and the lower side of the quick-release cover is attracted to the copper sheet conveying track by multiple magnets. The linear vibrating conveyor can realize the stable conveying of copper sheets in the copper sheet conveying track. The quick-release cover can be removed at any time to pick up or sort the copper sheets being conveyed, solving the problem of the existing technology where the conveying channel is closed and it is impossible to solve the problem of stuck copper sheets in time.
[0007] Preferably, a stop cylinder is installed on the side of the copper sheet conveying track near the lifting chamber. The stop cylinder is connected to a stop bar that passes laterally through the copper sheet conveying track. The stop cylinder can ensure that the copper sheets enter the lifting chamber one by one, preventing the copper sheets from interfering and overlapping.
[0008] And / or, at least one photoelectric sensor switch is installed on the side of the copper sheet conveying track to detect the copper sheets inside it. This switch can sense the position of the copper sheets being conveyed inside the track and provide an alarm signal when an abnormality occurs.
[0009] Preferably, the insert station assembly includes a positioning sleeve. A bearing connected to a rotating disk is installed on the outer side of the positioning sleeve. An indexing positioning ring is also provided on the outer side of the positioning sleeve. A limit stop ring is installed on one axial side of the indexing positioning ring. Positioning grooves matching the number of copper sheets are evenly distributed on the radial outer side of the indexing positioning ring. Elastic ejectors corresponding to the positioning grooves are radially installed on the edge of the rotating disk. The positioning sleeve can rotate around the rotating disk to meet the indexing rotation requirements of the plastic shell inside. At the same time, the indexing positioning ring rotates with the positioning sleeve. When the positioning grooves and elastic ejectors are engaged, the positioning sleeve will not rotate without external force, ensuring the accuracy of copper sheet insertion and preventing the copper sheets from damaging the plastic shell.
[0010] Preferably, the plastic shell indexing rotation assembly includes a mounting base plate and a sliding plate disposed on the upper side of the mounting base plate. A rotating shaft seat is mounted on the upper end of the sliding plate, and a main shaft is transversely inserted into the rotating shaft seat. The sheet insert is connected to one end of the main shaft, and a drive motor is mounted on the other end of the main shaft. A second transverse cylinder for driving the sliding plate to slide is mounted on one side of the mounting base plate. The second transverse cylinder can drive the sheet insert to accurately extend into the plastic shell, and the rotating shaft seat can ensure that the main shaft will not deviate when rotating.
[0011] Preferably, the plastic shell feeding and conveying assembly includes a transverse conveying body, inside which a transverse conveying channel for plastic shells is provided. The upper side of the transverse conveying body is connected to the plastic shell feeding vibratory feeder via the plastic shell feeding channel. A plastic shell positioning sleeve is installed at the first end of the transverse conveying body. A pusher block is transversely movable inside the transverse conveying channel for plastic shells. Driven by a pusher cylinder located at the second end of the transverse conveying body, the pusher block moves transversely, pushing the plastic shells falling from the plastic shell feeding and conveying channel into the plastic shell positioning sleeve. The plastic shell pushing assembly, the plastic shell positioning sleeve, and... The first station is coaxially set up, with the plastic shell unloading conveyor channel and the plastic shell transverse conveyor channel vertically connected. Combined with the precise stroke control of the pusher cylinder, it realizes the unmanned conveying of the plastic shell from the hopper to the positioning sleeve, avoiding the low efficiency and posture deviation problems of traditional manual feeding. The size of the plastic shell transverse conveyor channel is adapted to the plastic shell, and the rigid push of the pusher block, combined with the inner wall guidance of the plastic shell positioning sleeve, meets the axial tolerance requirements of the insertion machine station. At the same time, by using the matching structure of the precision positioning mandrel with the inner hole and inner groove of the plastic shell, the circumferential positioning accuracy of the plastic shell is ±1°, ensuring that the copper plate slot on the side wall of the plastic shell is precisely aligned with the pin insertion station of the insertion machine.
[0012] Preferably, a floating strip is provided on the inner bottom of the transverse conveying body near the plastic shell positioning sleeve. The end of the floating strip away from the plastic shell positioning sleeve is rotatably connected to the transverse conveying body and an elastic element is installed at the rotatable position. Multiple protrusions are provided on the upper side of the floating strip. The plastic shell can rotate when it comes into contact with the floating strip, so that the plastic shell will not get stuck in the transverse conveying channel. At the same time, the floating strip can prevent the plastic shell from moving backward after it enters the plastic shell positioning sleeve.
[0013] Preferably, an anti-retraction block is provided on the inner top of the transverse conveying body near the plastic shell positioning sleeve. A tongue spring pressure plate is installed on the lower side of the anti-retraction block. One end of the tongue spring pressure plate is connected to the anti-retraction block, and the other end extends to the position of the plastic shell positioning sleeve. The tongue spring pressure plate can always maintain contact with the pusher block when the plastic shell is pushed by the pusher block, ensuring that the pusher block can accurately push the plastic shell into the plastic shell positioning sleeve, and the plastic shell will not roll back after the pusher block retracts.
[0014] And / or, the end of the pusher block facing the plastic shell positioning sleeve is detachably equipped with a positioning claw, the end of the positioning claw is provided with an arc-shaped groove that matches the plastic shell, the positioning claw can be adjusted in angle, and can also be replaced according to different plastic shells.
[0015] Preferably, the plastic shell pushing assembly includes a driving assembly and a precision positioning mandrel mounted on the front end of the driving assembly. The driving assembly includes a vertical plate and a transverse slide rail mounted on the vertical plate. A third transverse cylinder is mounted on one end of the vertical plate. A second transverse slider connected to the third transverse cylinder is mounted on the transverse slide rail. A third transverse slider is also mounted on the transverse slide rail. A fourth transverse cylinder is mounted on the side wall of the second transverse slider and is connected to the third transverse slider. A positioning mandrel clamping seat is mounted on the upper side of the third transverse slider. The positioning mandrel is clamped along the axial direction at the front end of the positioning mandrel clamping seat. The second and third transverse sliding blocks can be pushed to slide synchronously by the third transverse sliding cylinder. After the second transverse sliding block is in place, the third transverse sliding block is pushed forward by the fourth transverse sliding cylinder. The purpose of the third transverse sliding cylinder is to move the precision positioning mandrel to a position close to the plastic shell. Then, the stroke of the fourth transverse sliding cylinder is relatively short. Its purpose is to correct the circumferential position of the plastic shell by pushing the precision positioning mandrel into contact with the plastic shell. After correction, the third transverse sliding cylinder pushes the plastic shell out of the plastic shell positioning sleeve and into the working position of the rotating disk.
[0016] Compared with the prior art, the beneficial effects of the present invention are:
[0017] In the technical solution of this invention, the copper sheet no longer relies on its own weight to pass through a long and winding material channel. The insertion method is changed from vertical insertion to horizontal insertion. The combination of the copper sheet transverse conveyor line and the copper sheet insertion assembly can achieve stable and smooth conveying and one-by-one gripping of the copper sheet. At the same time, the combination of the plastic shell unloading conveyor assembly, the plastic shell pushing assembly, and the plastic shell indexing rotation assembly can achieve smooth conveying and precise positioning of the plastic shell. Precise indexing rotation is performed during insertion to achieve rapid insertion. This comprehensively solves the problems of easy jamming during the conveying of copper sheets and plastic shells and low insertion and positioning accuracy of plastic shells and copper sheets in existing insertion machines.

[0035] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.
[0036] like Figure 1-15As shown, this invention provides a solution to the problems of easy jamming and low positioning accuracy of copper sheet and plastic shell insertion in existing insertion machines. The invention provides the following technical solution: a horizontal automatic insertion machine for slotted commutators, including a plastic shell feeding vibratory plate 2 and a copper sheet feeding vibratory plate 1, and a rotating plate 3 vertically arranged between the plastic shell feeding vibratory plate 2 and the copper sheet feeding vibratory plate 1. The rotating plate 3 is driven to rotate by an indexing motor 4 on its first side. A first station, a second station, and a third station are evenly installed around the circumference of the rotating plate 3 near its edge. Insertion station assemblies 10 are installed in each of the first, second, and third stations. The plastic shell feeding vibratory plate 2 is connected to a plastic shell feeding conveying assembly 11, one end of which matches the first station on the rotating plate 3. A plastic shell feeding conveyor assembly 11 is equipped with a plastic shell pushing assembly 12 corresponding to the first station on one side to push the plastic shell D in the plastic shell feeding conveyor assembly 11 into the first station. A mounting bracket 13 is provided on the second side of the rotating disk 3. A copper sheet transverse conveying line 9 corresponding to the second station is installed on the mounting bracket 13. One end of the copper sheet transverse conveying line 9 is connected to the copper sheet feeding vibratory disk 1, and the other end is connected to the copper sheet insertion assembly 5. A plastic shell indexing rotation assembly 8 is installed on the first side of the rotating disk 3 above the indexing motor 4. The plastic shell indexing rotation assembly 8 includes a sheet insertion plug 86 that can extend into the second station and be inserted into the plastic shell D, and a drive motor 84 that drives the sheet insertion plug 86 to perform indexing rotation. A feeding conveyor component 7 corresponding to the third station and a discharge push rod assembly 6 are also installed on both sides of the rotating disk 3.
[0037] The technical solution adopted in this embodiment has three workstations: the first workstation is for plastic shell loading, the second workstation is for copper sheet insertion, and the third workstation is for finished product unloading. These three workstations are evenly distributed around the circumference of the rotating disk at an angle of 120°. Combined with the precise angle control of the indexing motor, continuous cycling of loading, insertion, and unloading is achieved, eliminating process waiting time. Compared to traditional single-station insertion machines, production efficiency is significantly improved. Simultaneously, the copper sheet E uses a horizontal conveying and insertion assembly to replace its own weight for vertical arrangement, completely solving the problem of material channel jamming caused by burrs and deformation, and significantly reducing the jamming rate. The plastic shell indexing rotation assembly 8 achieves precise circumferential indexing of the plastic shell through the sheet insertion plug and drive motor. Combined with the radial precision positioning of the insertion workstation assembly on the rotating disk, the alignment accuracy between the copper sheet and the plastic shell slot is controlled within ±0.05mm, improving the pass rate of the insertion process.
[0038] Specifically, the rotating disk 3 is made of 45# steel, with three mounting holes machined on its edge; the indexing motor can be a Panasonic A6 series servo motor, equipped with a 17-bit absolute encoder, with a rotational accuracy of ±1 arcminute. Driven by a planetary reducer, the rotating disk achieves a positioning time of ≤0.3 seconds for each 120° rotation. The connector 86 can be made of brass with a nickel-plated surface for corrosion resistance. Its head is machined with a spline structure to fit the inner hole of the plastic housing, ensuring no radial movement after insertion.
[0039] Among them, the unloading conveying component 7 can use multiple conveyor belts to connect and catch the commutator with the inserted plate pushed out by the unloading push rod assembly 6, and transport it to the hopper or material frame. The unloading push rod assembly 6 has a relatively simple structure. The structure of cylinder and push rod can realize the accurate push of the commutator.
[0040] In this embodiment, the copper sheet insertion assembly 5 includes a lifting chamber 54 located between the copper sheet transverse conveyor line 9 and the second station. The lifting chamber 54 is connected to a vertical slider 55 located below it. The vertical slider 55 is driven to rise and fall by a lifting cylinder 14 mounted on a mounting bracket 13. A first transverse slider 52, which slides transversely above the copper sheet transverse conveyor line 9, is mounted on the mounting bracket 13. An insertion rod 53, corresponding to the lifting chamber 54 at a higher position, is mounted on the first transverse slider 52. The first transverse slider 52 is driven by a first transverse cylinder 51 and, through the insertion rod 53, pushes the copper sheet E in the lifting chamber 54 into the plastic shell D in the second station. The lifting chamber 54 can realize the insertion of copper sheets into the plastic shell D in the second station. The copper sheet E conveyed laterally in the transverse conveyor line 9 is precisely gripped, and the inserting rod 53 can accurately push the copper sheet E out of the lifting chamber 54. In addition, a baffle 56 can be set on one side of the lifting chamber 54. When the lifting chamber 54 is in a low position, the baffle 56 seals the end of the lifting chamber 54, and the copper sheet E will not fall out of the lifting chamber 54. When the lifting chamber 54 rises, it can disengage from the baffle 56, and the copper sheet E can be smoothly inserted. The lifting chamber 54 can only hold one copper sheet E. The low-position receiving and high-position feeding action of the lifting cylinder avoids the overlap and interference of multiple copper sheets, and improves the insertion success rate. The first transverse cylinder 51 controls the thrust of the inserting rod 53 by adjusting the air pressure to match the resistance of the copper sheet inserting into the plastic shell and prevent the copper sheet from bending due to excessive thrust.
[0041] In this embodiment, the copper sheet transverse conveying line 9 includes a linear vibrating conveyor 94 and a copper sheet conveying track 95 installed on the upper side of the linear vibrating conveyor 94. The copper sheet conveying track 95 corresponds to the lifting chamber 54 located at a lower position. A quick-release cover plate 91 is installed on the upper side of the copper sheet conveying track 95. The lower side of the quick-release cover plate 91 is attracted to the copper sheet conveying track 95 by multiple magnets 96. The linear vibrating conveyor 94 can stably convey the copper sheets E in the copper sheet conveying track 95. The quick-release cover plate 91 can be removed at any time to pick up or organize the copper sheets E in the conveying process. This solves the problem of the existing technology where the conveying channel is closed and it is impossible to solve the problem of stuck copper sheets in time. Specifically, the linear vibrating conveyor 94 makes the copper sheets E slide along the track at a uniform speed through high-frequency low-amplitude vibration, avoiding the stacking and flipping of copper sheets caused by traditional gravity sliding, thus improving the conveying stability. The magnets 96 are evenly arranged on the lower edge of the quick-release cover plate 91, making it very convenient to directly pick up and put down the quick-release cover plate 91.
[0042] In this embodiment, a stop cylinder 92 is installed on the side of the copper sheet conveying track 95 near the lifting chamber 54. The stop cylinder 92 is connected to a stop bar that passes laterally through the copper sheet conveying track 95. The stop cylinder 92 can ensure that the copper sheets E enter the lifting chamber 54 one by one, preventing the copper sheets E from interfering and overlapping.
[0043] And / or, at least one photoelectric sensor switch 93 is installed on the side of the copper sheet conveying track 95 to detect the copper sheet E inside it. It can sense the position of the copper sheet E conveyed inside the copper sheet conveying track 95 and give an alarm signal when a conveying abnormality occurs. Specifically, the photoelectric sensor switch 93 can detect the "presence" and "position" of the copper sheet in the track in real time. When "material shortage" or "material blockage" occurs, it immediately triggers the equipment to stop and alarm to avoid the equipment running idle or overloaded. When the lifting chamber 54 is in a low position and there is no copper sheet, the stop cylinder 92 retracts. The copper sheet E is conveyed to the photoelectric sensor switch 93 by vibration. The switch detects the copper sheet E, the stop cylinder 92 extends to block the subsequent copper sheet. When the lifting chamber 54 rises to receive the material, the copper sheet E is inserted and then the lifting chamber 54 resets, the stop cylinder 92 retracts again, and the next cycle begins. If the switch does not detect a copper sheet for 3 consecutive seconds or detects a copper sheet for 2 consecutive seconds, the PLC control equipment stops, the buzzer alarms, and the touch screen displays the "material shortage / material blockage" fault code.
[0044] In this embodiment, the insert station assembly 10 includes a positioning sleeve 102. A bearing 101 connected to the rotating disk 3 is mounted on the outer side of the positioning sleeve 102. An indexing positioning ring 103 is also provided on the outer side of the positioning sleeve 102. A limit stop ring 105 is installed on one axial side of the indexing positioning ring 103. Positioning grooves matching the number of copper sheets E are evenly distributed on the radially outer side of the indexing positioning ring 103. Elastic ejector pins 104 corresponding to the positioning grooves are radially mounted on the edge of the rotating disk 3. The positioning sleeve 102 can rotate around the rotating disk 3 to meet the indexing rotation requirements of the internally positioned plastic shell D. Simultaneously, the indexing positioning ring 103... The positioning sleeve 102 rotates, and when the positioning groove engages with the elastic ejector pin 104, the positioning sleeve 102 will not rotate without external force, ensuring the accuracy of copper sheet insertion and preventing damage to the plastic shell D. Specifically, the gap between the positioning sleeve 102 and the plastic shell D is only 0.1mm, which, together with the axial blocking of the limiting ring 105, prevents the plastic shell D from shifting during the insertion process, ensuring consistent copper sheet insertion depth. The elastic ejector pin 104 is a MISUMI model PNY10-5 with a pin diameter of 2mm, a stroke of 5mm, an internal spring, and a preload of 5N. It is fixed to the edge of the rotating disk with an M5 thread, and the ejector pin axis is radially aligned with the positioning ring to ensure that the ejector pin can be accurately embedded in the groove.
[0045] In this embodiment, the plastic shell indexing rotation assembly 8 includes a mounting base plate 81 and a sliding plate 82 disposed on the upper side of the mounting base plate 81. A rotating shaft seat 83 is mounted on the upper end of the sliding plate 82, and a main shaft 87 is transversely connected inside the rotating shaft seat 83. The plate insert 86 is connected to one end of the main shaft 87, and a drive motor 84 is mounted on the other end of the main shaft 87. A second transverse cylinder 85 for driving the sliding plate 82 to slide is mounted on one side of the mounting base plate 81. The second transverse cylinder 85 can drive the plate insert 86 to accurately extend into the plastic shell D. The rotating shaft seat 83 can ensure that the main shaft 87 will not deviate when rotating. Specifically, after the rotating disk 3 sends the plastic shell to the second station, the second transverse cylinder 85 drives the plate insert 86 to insert into the plastic shell D. Then the drive motor 84 rotates 15°, corresponding to one indexing, and the elastic pin 104 is embedded in the positioning groove. Then the copper plate is inserted, and the motor rotates 15° again. This cycle continues until all copper plates are inserted, and the insert is withdrawn.
[0046] In this embodiment, the plastic shell feeding and conveying assembly 11 includes a transverse conveying body 111. The transverse conveying body 111 has a plastic shell transverse conveying channel 1112 inside. The upper side of the transverse conveying body 111 is connected to the plastic shell feeding vibratory feeder 2 via the plastic shell feeding conveying channel 112. A plastic shell positioning sleeve 115 is installed at the first end of the transverse conveying body 111. A pusher block 1111 is transversely movable inside the plastic shell transverse conveying channel 1112. The pusher block 1111 moves laterally under the drive of a pusher cylinder 114 at the second end of the transverse conveying body 111, pushing the plastic shell D falling in the plastic shell feeding and conveying channel 112 into the plastic shell positioning sleeve 115. The shell pushing assembly 12 is coaxially arranged with the plastic shell positioning sleeve 115 and the first station. The plastic shell unloading conveying channel 112 and the plastic shell transverse conveying channel 1112 are vertically connected. Combined with the precise stroke control of the pushing cylinder 114, the plastic shell is conveyed from the hopper to the positioning sleeve without manual intervention, avoiding the low efficiency and posture deviation problems of traditional manual feeding. The size of the plastic shell transverse conveying channel 1112 is adapted to the plastic shell. The rigid pushing of the pushing block 1111 is coordinated with the inner wall guidance of the plastic shell positioning sleeve to meet the axial tolerance requirements of the insertion machine station. At the same time, by using the matching structure of the precision positioning mandrel 127 with the inner hole and inner groove of the plastic shell, the circumferential positioning accuracy of the plastic shell is ±1°, ensuring that the copper plate slot on the side wall of the plastic shell is precisely aligned with the insertion pin station of the insertion machine.
[0047] In this embodiment, a floating strip 1116 is provided on the inner bottom of the transverse conveying body 111 near the plastic shell positioning sleeve 115. The end of the floating strip 1116 away from the plastic shell positioning sleeve 115 is rotatably connected to the transverse conveying body 111 and an elastic element 1117 is installed at the rotatable position. Multiple protrusions 1118 are provided on the upper side of the floating strip 1116. The plastic shell D can rotate when it comes into contact with the floating strip 1116, so that the plastic shell D will not get stuck in the plastic shell transverse conveying channel 1112. At the same time, the floating strip 1116 can prevent the plastic shell D from moving backward after it enters the plastic shell positioning sleeve 115.
[0048] In this embodiment, an anti-retraction block 1113 is provided on the inner top of the transverse conveying body 111 near the plastic shell positioning sleeve 115. A tongue spring pressure plate 1114 is installed on the lower side of the anti-retraction block 1113. One end of the tongue spring pressure plate 1114 is connected to the anti-retraction block 1113, and the other end extends to the position of the plastic shell positioning sleeve 115. When the plastic shell D is pushed by the pusher block 1111, the tongue spring pressure plate 1114 can always maintain contact with the pusher block 1111, ensuring that the pusher block 1111 can accurately push the plastic shell D into the plastic shell positioning sleeve 115. Moreover, after the pusher block 1111 retracts, the plastic shell D will not roll back. The tongue spring pressure plate 1114 always adheres to the upper surface of the plastic shell through elastic deformation, forming an "elastic clamping". When the pusher block 1111 retracts, the friction between the pressure plate and the plastic shell D is much greater than the sliding resistance of the plastic shell, completely preventing the plastic shell from retracting.
[0049] The pusher block 1111 has a detachable positioning claw 1115 at one end facing the plastic shell positioning sleeve 115. The end of the positioning claw 1115 is provided with an arc-shaped groove that matches the plastic shell B. The positioning claw 1115 can be adjusted in angle and can also be replaced according to different plastic shells D.
[0050] In this embodiment, the transverse conveying body 111 includes a back plate 1119, a front plate, and an upper baffle 1124 and a lower baffle 1123 disposed between the back plate 1119 and the front plate. The plastic shell positioning sleeve 115 is embedded in the back plate 1119, and the floating strip 1116 is embedded in the lower baffle 1123. The structure is simple, and assembly and adjustment are convenient. With the above-mentioned modular structure, the components are connected by bolts, which reduces assembly time and facilitates the individual replacement of damaged components. The upper baffle 1124 and the lower baffle 1123 are milled to ensure parallelism, ensuring the dimensional accuracy of the transverse conveying channel of the plastic shell and avoiding the plastic shell jamming caused by channel deformation.
[0051] The outer radial circumference of the plastic housing positioning sleeve 115 is provided with an axial limiting groove, and the back plate 1119 is provided with a screw hole 1121 corresponding to the axial limiting groove. The circumferential position of the plastic housing positioning sleeve 115 can be adjusted by inserting a positioning screw into the screw hole 1121 to match different plastic housings D and ensure the accurate positioning of the plastic housing D.
[0052] Meanwhile, a first feeding cylinder 117 and a second feeding cylinder 116 are installed side by side at the lower end of the plastic shell feeding conveying channel 112. Both the first feeding cylinder 117 and the second feeding cylinder 116 are equipped with a baffle rod 118 that is inserted horizontally into the plastic shell feeding conveying channel 112. Through the alternating operation of the first feeding cylinder 117 and the second feeding cylinder 116, it can be ensured that only one plastic shell D falls from the plastic shell feeding conveying channel 112 into the plastic shell horizontal conveying channel 1112 at a time. The operating frequency of the first feeding cylinder 117 and the second feeding cylinder 116 can be adjusted by PLC to perfectly match the pushing rhythm of the pushing cylinder 114, so as to achieve seamless connection between feeding and pushing and improve overall efficiency.
[0053] In this embodiment, the plastic shell pushing assembly 12 includes a driving assembly and a precision positioning mandrel 127 mounted on the front end of the driving assembly. The driving assembly includes a vertical plate 121 and a transverse slide rail mounted on the vertical plate 121. A third transverse cylinder 122 is mounted on one end of the vertical plate 121. A second transverse slider 123 connected to the third transverse cylinder 122 is mounted on the transverse slide rail. A third transverse slider 125 is also mounted on the transverse slide rail. A fourth transverse cylinder 124 is mounted on the side wall of the second transverse slider 123. The fourth transverse cylinder 124 is connected to the third transverse slider 125. A positioning mandrel clamping seat 126 is mounted on the upper side of the third transverse slider 125. The positioning mandrel 127 is clamped along the axial direction at the front end of the positioning mandrel clamping seat 126. The second transverse slider 123 and the third transverse slider 125 can be pushed to slide synchronously by the third transverse cylinder 122. After the second transverse slider 123 is in place, the third transverse slider 125 is pushed forward by the fourth transverse cylinder 124. The purpose of the third transverse cylinder 122 is to move the precision positioning mandrel 127 to a position close to the plastic shell D. Then, the stroke of the fourth transverse cylinder 124 is relatively short. Its purpose is to correct the circumferential position of the plastic shell D by pushing the precision positioning mandrel 127 into contact with the plastic shell D. After correction, the third transverse cylinder 122 pushes the plastic shell D out of the plastic shell positioning sleeve 115 and into the station of the rotating disk.
[0054] In this embodiment, the complete workflow is as follows:
[0055] 1. Initialization phase:
[0056] Start the equipment, the PLC controls all cylinders to reset, the lifting cylinder 14 retracts to put the lifting chamber 54 in the low position, the stop cylinder 92 extends the blocking copper plate, and each transverse cylinder retracts.
[0057] The indexing motor 4 drives the rotating disk 3 to reset, so that the first station is aligned with the plastic shell positioning sleeve 115 of the plastic shell unloading and conveying assembly 11, the second station is aligned with the copper sheet insertion assembly 5, and the third station is aligned with the unloading and conveying component 7.
[0058] Setting parameters: Rotary disk rotation angle 120°, copper sheet insertion cycle 1.2 seconds, plastic shell indexing angle 15°, alarm delay time 3 seconds.
[0059] 2. Plastic shell feeding and first station positioning
[0060] Plastic shell conveying: The plastic shell feeding vibratory feeder 2 is started, and the plastic shell is vertically conveyed along the feeding channel to the plastic shell transverse conveying channel 1112. The corner radius at the joint is R3mm to avoid jamming.
[0061] The plastic shell is pushed into the positioning sleeve: the pusher cylinder 114 drives the pusher block 1111 to move, and the arc-shaped groove of the positioning claw 1115 fits the plastic shell D, pushing the plastic shell D into the plastic shell positioning sleeve 115; at this time, the floating strip 1116 fits the bottom of the plastic shell D under the support of the elastic element 1117, and the tongue spring pressure plate 1114 fits the top of the plastic shell D to prevent the plastic shell D from moving backward.
[0062] The plastic shell is pushed into the first station: the plastic shell pushing assembly 12 is started, the third transverse cylinder 122 drives the precision positioning mandrel 127 to approach the plastic shell, the fourth transverse cylinder 124 drives the precision positioning mandrel 127 to insert into the inner groove of the plastic shell D, the third transverse cylinder 122 continues to push, pushing the plastic shell D into the positioning sleeve 102 of the first station, the precision positioning mandrel 127 is withdrawn, and the plastic shell pushing assembly 12 is reset.
[0063] 3. Rotary workstation switching
[0064] The indexing motor 4 drives the rotating disk to rotate 120°, sending the first station containing the plastic shell D to the second station. At the same time, the empty second station rotates to the first station, and the third station containing the finished product rotates to the unloading position.
[0065] During rotation, the elastic pin 104 of the insert station assembly 10 always fits against the indexing positioning ring 103. After rotation into position, the elastic pin 104 is embedded in the positioning groove to achieve mechanical positioning.
[0066] 4. Copper sheet feeding and connection to the second station
[0067] Copper sheet conveying: The copper sheet feeding vibratory feeder 1 is started, and the copper sheet E is conveyed along the copper sheet transverse conveying line 9. The quick-release cover plate 91 is made of transparent material, which can be observed in real time. After the photoelectric sensor switch 93 detects that the copper sheet E is in place, the stop cylinder 92 retracts, allowing one copper sheet E to enter the lifting chamber 54.
[0068] Copper sheet lifting and insertion: Lifting cylinder 14 drives lifting chamber 54 to rise to a high position, first transverse cylinder 51 drives inserting rod 53 to push out, inserting copper sheet E into plastic shell slot, inserting rod 53 to retract, lifting chamber 54 descends to reset.
[0069] Plastic shell indexing rotation: The plastic shell indexing rotation assembly 8 is started, the second transverse cylinder 85 drives the plate inserter 86 to insert into the inner hole of the plastic shell, the drive motor 84 is a stepper motor, driving the plastic shell to rotate 15°, the elastic ejector pin 104 is embedded in the next positioning groove, and the copper plate insertion action is repeated until all 24 copper plates E are inserted, and the plug is withdrawn.
[0070] 5. Finished product unloading
[0071] Rotating disk 3 rotates 120° again, and the second station containing the finished product moves to the third station;
[0072] When the unloading push rod assembly 6 is activated, the finished product is pushed out of the positioning sleeve to the unloading conveyor component 7, and the finished product is conveyed to the material frame;
[0073] Meanwhile, the empty third workstation is moved to the first workstation to begin the next cycle.
[0074] 6. Exception Handling
[0075] Material shortage alarm: If the photoelectric sensor switch 93 fails to detect copper sheet for 3 consecutive seconds, or if the plastic shell vibratory feeder is out of material, the equipment will stop, the buzzer will sound an alarm, and the touch screen will display "Copper sheet shortage / Plastic shell shortage".
[0076] Material jamming handling: If the copper sheet is stuck in the copper sheet conveying track 95, the quick-release cover plate 91 can be removed directly, the stuck copper sheet can be cleared and the process restarted; if the plastic shell D is stuck in the transverse channel, the pusher cylinder can be manually triggered to reset and the plastic shell can be removed.
[0077] Overload protection: When the motor current exceeds 1.2 times the rated value, the PLC will immediately cut off the motor power supply to avoid damage to components.
