Description

Technical Field

[0001] This invention relates to the field of reel tray packaging equipment, and more particularly to an automatic protective tape applicator for trays of various sizes. Background Technology

[0002] Reel reel trays are widely used for the storage and transportation of electronic components (such as capacitors, resistors, and inductors). They are usually wrapped with a protective strip to provide protection, insulation, and mechanical strength for the electronic components in the tray.

[0003] The equipment for attaching protective tape to material trays is generally automated, capable of automatically attaching the protective tape to the trays. However, in industrial production, there are various sizes of material trays. In order to save equipment costs and factory space costs, how to automatically attach protective tape to material trays of various sizes on the same equipment is a technical problem that urgently needs to be solved. Summary of the Invention

[0004] The purpose of this invention is to provide an automatic protective tape applicator for trays of various sizes. The tape applicator has a tape applicator horizontal movement component with staggered vertical arrangement, which works in conjunction with the corresponding tape applicator structure. The tape applicator lifting component adjusts the overall height, so that the tape applicator structure with the required size of protective tape can be aligned with the tape applicator turntable, thereby completing the application of protective tapes of various sizes and specifications on a single machine.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows: an automatic protective tape applicator for trays capable of adapting to various specifications, comprising a tray conveying device, a conveying lifting device, a tape applicator turntable device, and a tape applicator mechanism mounted on a frame. The conveying lifting device is equipped with a transport and transfer device, which transports the trays to a tray flipping device on the frame. The frame is also equipped with an identification module for identifying the trays on the tray flipping device and an error tray storage rack for storing trays with incorrect information. The frame is also equipped with a tape-finding and transporting mechanism for finding the tape head of the trays flipped by the tray flipping device and transporting them to the tape applicator turntable device. The tape applicator mechanism includes a tape applicator frame on the frame, a tape applicator lifting assembly on the tape applicator frame, a tape applicator lifting seat connected to the tape applicator lifting assembly, and tape applicator lateral movement assemblies staggered in the vertical direction on the tape applicator lifting seat. Each tape applicator lateral movement assembly is equipped with a tape applicator structure and drives the tape applicator structure to move laterally. The protective tape conveyor device on each tape applicator structure transports a different specification of protective tape.

[0006] The tape application mechanism of this solution uses a tape application transverse moving component with staggered upper and lower positions to work with the corresponding tape application structure, and then uses a tape application lifting component to adjust the overall height. In this way, the tape application structure with the required size of protective tape can be aligned with the tape application turntable device, and thus the application of protective tape of various sizes and specifications can be completed on a single machine.

[0007] Preferably, the tape-applying structure includes a tape-applying seat, on which a protective tape docking block is provided. The protective tape docking block is equipped with a protective tape conveying device that can pass the protective tape through the protective tape docking block. An inner adhesive applicator and an outer adhesive applicator are respectively provided on both sides of the protective tape docking block for bonding the material tape and the protective tape. A protective tape shifting cylinder is provided at the bottom of the tape-applying seat. The protective tape shifting cylinder is connected to a protective tape shifting movable seat. Two protective tape conveying devices are provided on the protective tape shifting movable seat.

[0008] In this preferred embodiment, each tape-applying seat is equipped with two adjustable protective tape conveying devices. These devices can accommodate protective tapes of the same specification, allowing for tape application even when changing protective tapes, or they can accommodate protective tapes of different specifications.

[0009] Preferably, the inner adhesive applicator includes an inner adhesive applicator movable component mounted on the tape base. The inner adhesive applicator movable component is connected to an inner adhesive applicator movable seat. An inner adhesive roll, an inner adhesive discharge tube, an inner adhesive guide tube, and an inner adhesive block are mounted on the inner adhesive applicator movable seat. The inner adhesive discharge tube is equipped with an inner adhesive discharge motor. The inner adhesive block has an inner adhesive adsorption hole for negative pressure adsorption of the inner adhesive tape. An inner adhesive cutting cylinder is mounted on the inner adhesive applicator movable seat. The inner adhesive cutting cylinder is connected to an inner adhesive cutting knife, and the inner adhesive cutting knife is conical in shape for cutting the center of the inner adhesive tape.

[0010] The inner adhesive applicator of this preferred embodiment uses a conical design of the inner cutting blade to cut the inner tape without severing it, thus facilitating tape connection and unwinding. Finally, the inner tape is pulled apart by the winding of the tape applicator turntable and the adsorption of the inner adhesive adsorption holes.

[0011] Preferably, the inner adhesive movable seat is provided with a reciprocating pressing cylinder, the pressing cylinder is connected to a pressing block, the pressing block is used to press the adhesive protective tape and the inner adhesive tape of the material head tightly, and the pressing part of the pressing block is a brush structure.

[0012] This preferred solution, through the design of the pressing cylinder, can press the inner tape tightly onto the material head and the protective belt, ensuring the adhesion of the inner tape.

[0013] Preferably, the external adhesive applicator includes an external adhesive applicator movable component on an adhesive tape holder, which is connected to an external adhesive applicator movable seat. The external adhesive applicator movable seat is provided with an external adhesive roll, an external adhesive discharge tube, an external adhesive guide tube, and an external adhesive block. The external adhesive discharge tube is equipped with an external adhesive discharge motor. One of the external adhesive guide tubes is a movable adhesive guide tube, which is equipped with a guide tube reciprocating motor. The external adhesive discharge tube is provided with a folding ear air blowing hole, and the adhesive tape is blown into the folding ear seat provided on the external adhesive applicator movable seat. The external adhesive applicator movable seat is connected to a folding ear block through a folding ear cylinder. The folding ear block is used to adhere the adhesive tape blown into the folding ear seat. The external adhesive block is provided with an external adhesive adsorption hole for adsorbing the external adhesive tape. The external adhesive applicator movable seat is also provided with an external adhesive cutting cylinder, which is connected to an external adhesive cutting knife. The external adhesive cutting knife is conical and is used to make an opening in the center of the external adhesive tape.

[0014] The preferred solution's external adhesive applicator uses a movable adhesive guide tube and an air blowing hole to loosen and blow the external adhesive tape into the folding ear seat, which, together with the folding ear block, completes the folding operation. After the external adhesive tape is applied, can the tape end be easily located during subsequent use?

[0015] Preferably, the tape application turntable device includes a tape application turntable base mounted on a frame, a tape application turntable lifting structure mounted on the tape application turntable base, the tape application turntable lifting structure driving the tape application shaft to rise and fall, and the tape application shaft and the tape application turntable lifting structure can rotate relative to each other, the tape application shaft is connected to a tape application motor through a transmission structure, a tape application arm is sleeved on the tape application shaft, the tape application arm is connected to a rotating arm motor through a transmission structure, a pressure block shaft is mounted on the tape application arm, a tape application pressure block is mounted on the pressure block shaft, and the tape application pressure block is connected to a pressure block motor through a transmission structure.

[0016] The tape-applying turntable device of this preferred embodiment can realize the separate rotation of the tape-applying shaft, the tape-applying arm, and the pressure block shaft without interference between them. Compared with the track-type pressure block structure, it can reduce the space used in the frame panel and avoid interference with other structures.

[0017] Preferably, the lead-finding conveying mechanism includes a material tray unwinding device mounted on the frame and a material tray pushing structure that pushes the material tray, which is placed flat by the material tray flipping device, to the material tray unwinding device. The frame is equipped with two parallel lead-finding sensors and a lead-finding air blowing block that blows the lead-finding strip unwound by the material tray unwinding device into the lead-finding sensors. The signals from the two lead-finding sensors are used to control the unwinding and rewinding of the material tray unwinding device. The frame is also equipped with a clamping conveying device for transporting the material tray on the material tray unwinding device to the tape-attaching turntable device, and the clamping conveying device clamps the lead-finding strip unwound from the material tray during transport.

[0018] This preferred solution uses air blowing and two parallel sensors to control the unwinding state of the material tray by generating signals from the two sensors. This allows the material tray to be unwound to a specific length. When combined with a clamping and conveying device that can clamp the tape head, the position of the tape head of the material tray is determined while it is being transported, so that it can be accurately attached to the protective tape later.

[0020] This preferred embodiment features two clamping swing arms on the main rod of the pallet chuck, with the main rod as the rotation center, thus enabling the clamping operation to be completed simultaneously with the pallet clamping.

[0021] Preferably, the conveyor seat is provided with two conveyor chucks, and the distance between the centers of the two conveyor chucks is the distance between the centers of the tape-attaching turntable device and the material tray unwinding device. Only the conveyor chucks near the material tray unwinding device are provided with a tape-clamping swing arm.

[0022] This preferred solution improves overall efficiency by using two transfer clamps to simultaneously clamp the tray for finding the tape head and the tray for applying the tape on the tape turntable.

[0023] Preferably, the frame panel is provided with an arc-shaped clamping groove centered on the rotation center of the material tray unwinding device. When the clamping block is clamping the tape head, it is inserted into the clamping groove and moves within the clamping groove to clamp the tape head. The clamping and conveying movable seat is provided with two vertically oriented pressure plate cylinders that are symmetrical about the conveying clamping plate near the material tray unwinding device. Both pressure plate cylinders are connected to pressure plate blocks.

[0024] This preferred solution, through the design of the clamping groove, can limit the running trajectory of the clamping block and also position the pallet chuck. The design of the pressure plate block can press the pallet down during the clamping process, preventing the pallet from moving. Attached Figure Description

[0046] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of the present invention in any way.

[0047] like Figure 1-2 and Figure 12 As shown, the specific structure of the present invention is as follows: an automatic protective tape applicator for trays capable of adapting to various specifications, including a tray conveying device 1, a conveying lifting device 2, a tape applicator turntable device 7, and a tape applicator mechanism 8 mounted on a frame. The conveying lifting device 2 is equipped with a transport and transfer device 3, which transports the trays to a tray flipping device 4 on the frame. The frame is also equipped with an identification module for identifying the trays on the tray flipping device 4 and an error tray storage rack 5 for storing trays with incorrect information. The frame is also equipped with a tape-finding and transporting mechanism 6 for finding the tape head of the trays flipped by the tray flipping device 4 and transporting them to the tape applicator turntable device. The tape applicator mechanism 8 includes components mounted on the frame. The tape applicator 81 is equipped with a tape applicator lifting assembly 82, which is connected to a tape applicator lifting seat 83. Tape applicator lifting seat 83 is equipped with tape applicator lateral movement assemblies 84 arranged alternately in the vertical direction. Each tape applicator lateral movement assembly 84 is matched with a tape applicator structure 85 and drives the tape applicator structure to move laterally. The protective tape conveyor on each tape applicator structure conveys a different specification of protective tape. The material tray conveyor 1 includes a double-layer conveyor frame 10. The conveyor frame 10 is equipped with a feeding conveyor belt 11 and an output conveyor belt 14 with opposite conveying directions for conveying the material tray box 12. The conveyor lifting device 2 is connected to the feeding conveyor belt 11 and the output conveyor belt 14 through a lifting structure.

[0048] The specific operation process of this solution is as follows: The tray box 12 filled with material trays is placed on the feeding conveyor belt 11. After being conveyed by the feeding conveyor belt 11, it enters the transmission lifting device 2 and rises with the transmission lifting device 2. Then, the products standing upright in the tray box 12 are transferred one by one to the tray flipping device 4 by the handling and transfer device 3. The information of the tray is identified by the identification module. If the identified information is incorrect, the tray is flipped to the wrong tray storage rack 5 by the tray flipping device 4. If the information is correct, the tray is sent to the tape finding station by the tray flipping device 4. After the tape finding mechanism 6 completes the tape finding of the tray, it is transferred to the tape application turntable device 7. At the same time, the tape application mechanism obtains the size and specifications of the tray according to the identified information. Then, the tape application lifting component 82 and each tape application lateral movement component 84 work together to make the height and position of the tape application structure 85 of the corresponding size and specifications correspond to the tape application turntable device 7. After that, the protective tape joining operation can be performed.

[0049] like Figure 12-15 As shown, the tape-applying structure 85 includes a tape-applying seat 86, on which a protective tape docking block 90 is provided. The protective tape docking block 90 is equipped with a protective tape conveying device 89 that can pass the protective tape through the protective tape docking block 90. ​​An inner adhesive applicator 87 and an outer adhesive applicator 88 for bonding the material tape and the protective tape are respectively provided on both sides of the protective tape docking block 90. ​​A protective tape shifting cylinder 103 is provided at the bottom of the tape-applying seat 86. The protective tape shifting cylinder 103 is connected to a protective tape shifting movable seat 104. Two protective tape conveying devices 89 are provided on the protective tape shifting movable seat 104.

[0050] After the tape structure position is adjusted, the protective tape shifting cylinder 103 can drive the protective tape shifting movable seat 104 to move, so that the required protective tape conveying device 89 is aligned with the protective tape docking block 90. ​​Then, the protective tape is fed into the protective tape docking block 90 by the protective tape conveying device 89 and passes through the protective tape docking block 90. ​​Then, the inner adhesive device 87 is used to bond the tape head of the material tray to the protective tape, achieving a precise connection between the protective tape and the tape head. Then, the tape-applying turntable device 7 drives the material tray to rotate and rewind the joined part. At the same time, the outer adhesive device 88 also bonds the tape head and the outer side of the protective tape. After the inner and outer adhesives are applied and the rewinding is completed, the outer tape will bond the end of the protective tape to the entire material tray.

[0051] like Figure 16-17As shown, the protective belt conveying device 89 includes a protective belt conveying seat 91, on which a feeding drive roller for conveying is provided and a rotatable driven adjustment frame 93 is provided. The driven adjustment frame 93 is provided with a feeding slave roller 94 that cooperates with the feeding drive roller. The protective belt conveying seat 91 is provided with a feeding motor 92 for driving the feeding drive roller. The feeding conveying seat 91 is also provided with a feeding groove block 97 for the protective belt to pass through and guide the protective belt to pass through the feeding opening 98 opened on the protective belt conveying seat 91. The protective belt conveying seat 91 is provided with a cutting cylinder 99, which is connected to a cutting knife 100. The inlet of the feeding groove block 97 is a concave conical opening. The driven adjustment frame 93 is connected to a feeding adjustment rod 96, which is driven by a feeding adjustment cylinder 95.

[0052] The specific operation of the protective belt conveyor 89 is as follows: First, the end of the protective belt is passed through the feeding drive roller and the feeding driven roller 94. Then, the feeding adjustment cylinder 95 drives the feeding adjustment lever 96 to move, thereby causing the driven adjustment frame 93 to rotate, so that the feeding driven roller 94 cooperates with the feeding drive roller to achieve conveying. Then, the feeding motor 92 drives the feeding drive roller to rotate, so that the protective belt can be continuously conveyed. The protective belt will enter the feeding trough 97 from the concave conical opening of the feeding trough 97, and then pass out from the feeding port 98, and then enter the protective belt docking block 90. ​​After the required length of conveying is completed, the cutting cylinder 99 drives the cutting knife 100 to move and cut the protective belt that has entered the concave conical opening of the feeding trough 97.

[0053] like Figure 15 and Figure 18 As shown, the inner adhesive applicator 87 includes an inner adhesive applicator movable component 101 disposed on the tape holder 86. The inner adhesive applicator movable component 101 is connected to an inner adhesive applicator movable seat 111. An inner adhesive roll 112, an inner adhesive dispensing cylinder 113, an inner adhesive guide cylinder, and an inner adhesive applicator block 114 are installed on the inner adhesive dispensing cylinder 113, which is equipped with an inner adhesive dispensing motor. The inner adhesive applicator block 114 has an inner adhesive adsorption hole for negative pressure adsorption of the inner adhesive tape. An inner-cutting adhesive cylinder 115 is provided on the movable seat 111. The inner-cutting adhesive cylinder 115 is connected to an inner-cutting adhesive knife 116, which is a pointed cone shape and is used to cut the center of the inner adhesive tape. The inner-adhesive movable seat 111 is provided with a reciprocating pressing cylinder 117. The pressing cylinder 117 is connected to a pressing block 118. The pressing block 118 is used to press the inner adhesive tape of the bonding protective tape and the material head tightly, and the pressing part of the pressing block 118 has a brush structure.

[0054] In specific operation, the end of the inner tape roll 112 is first attached to the inner tape block 114 after passing through the inner tape release tube 113 and the inner tape guide tube. It is then adsorbed by the negative pressure of the inner tape adsorption hole (connected to a negative pressure component). Afterwards, the inner tape proximity movable seat 111 is moved as a whole by the inner tape proximity movable component 101, so that the inner tape block 114 can bond the inner tape to the material tray head and the protective tape end. After the initial bonding is completed, the inner tape adsorption hole does not perform negative pressure adsorption. While the tape reel device rotates and rewinds, the inner tape release motor drives the inner tape release drum 113 to press the inner tape. During unwinding, the inner cutting cylinder 115 drives the inner cutting knife 116 to cut the tape to the appropriate length. When applying the inner tape, the pressing block 118 reciprocates under the action of the pressing cylinder 117, thus pressing the inner tape tightly onto the tape head or protective tape. After the inner tape is applied, it is adsorbed by negative pressure through the inner tape adsorption hole. As the tape application turntable continues to rotate, the cut part of the inner tape is pulled off. Compared with the cutting method of the cutter, the cutter does not act on the protective tape at all.

[0055] like Figure 19 As shown, the external adhesive applicator 88 includes an external adhesive applicator movable component 102 on the tape applicator seat 86. The external adhesive applicator movable component 102 is connected to an external adhesive applicator movable seat 121. The external adhesive applicator movable seat 121 is provided with an external adhesive roll 122, an external adhesive dispensing tube 123, an external adhesive guide tube, and an external adhesive block 125. The external adhesive dispensing tube 123 is equipped with an external adhesive dispensing motor. One of the external adhesive guide tubes is a movable adhesive guide tube 124, which is equipped with a guide tube reciprocating motor. The external adhesive dispensing tube 123 is provided with a folded air blowing hole for the inlet tape. The tape is inserted into the folded ear seat 128 provided on the external adhesive movable seat 121, and the external adhesive movable seat 121 is connected to the folded ear block 130 through the folded ear cylinder 129. The folded ear block 130 is used to bond the tape blown into the folded ear seat 128. The external adhesive block 125 is provided with an external adhesive adsorption hole 127 for adsorbing the external adhesive tape. The external adhesive movable seat 121 is also provided with an external adhesive cutting cylinder 131, which is connected to an external adhesive cutting knife. The external adhesive cutting knife is conical and is used to make an opening in the center of the external adhesive tape.

[0056] The specific operation of applying the outer adhesive is as follows: Initially, the end of the outer adhesive roll 122 is passed through the outer adhesive tube 123 and the outer adhesive guide tube and then attached to the inner and outer adhesive blocks 125, and is attracted by the outer adhesive adsorption hole 127. Then, the outer adhesive tape is loosened by moving the movable adhesive guide tube 124. Then, the outer adhesive tape is blown into the folding ear seat 128 through the folding ear air blowing hole on the outer adhesive tube 123. Then, the folding ear cylinder 129 drives the folding ear block 130 to move, and the inner adhesive tape is adhered to each other through the folding ear block 130. The outer tape remains taut as the movable guide tube 124 returns to its original position. Simultaneously, the outer cutting cylinder 131 drives the outer cutting blade to cut the outer tape. Then, the outer adhesive attaching assembly 102 moves the outer adhesive attaching seat 121, allowing the outer adhesive attaching block 125 to bond the tape head and the protective tape. After bonding, the outer adhesive attaching suction hole 127 is released. After the outer adhesive is applied, the outer adhesive attaching suction hole 127 is reopened to continue adsorbing. As the tray continues to rotate, the outer tape is pulled off from the cut.

[0057] like Figure 20 As shown, the tape application turntable device 7 includes a tape application turntable base 141 mounted on a frame. A tape application turntable lifting structure 142 is provided on the tape application turntable base 141. The tape application turntable lifting structure 142 drives the tape application shaft to rise and fall, and the tape application shaft 142 can rotate relative to the tape application turntable lifting structure 142. The tape application shaft is connected to a tape application motor 143 through a transmission structure. A tape application arm 145 is sleeved on the tape application shaft. The tape application arm 145 is connected to a rotating arm motor 144 through a transmission structure. A pressure block rotating shaft 147 is mounted on the tape application arm 145. A tape application pressure block 148 is provided on the pressure block rotating shaft 147, and the tape application pressure block 148 is connected to a pressure block motor 146 through a transmission structure.

[0058] The specific operation of the tape application turntable device 7 is as follows: First, the tape application turntable lifting structure drives the tape application shaft to rise as a whole, ensuring that the tape application turntable can rotate synchronously. After the tape and protective tape are joined, the tape application motor 143 drives the tape application shaft to rotate, thereby driving the tape reel to wind up. At the same time as winding up, the rotating arm motor 144 drives the tape application arm 145 to rotate, thereby cooperating with the rotation of the tape application pressure block 148 to press the wound tape or protective tape. In this way, the outer tape is pressed on the outside of the protective tape and the outer tape completes the final bonding and sealing. After winding up, the pressure block motor 146 drives the pressure block shaft 147 to rotate, turning the tape application pressure block 148 open, so that the clamping and conveying device can take away the tape reel with the protective tape and place it on the finished product reel storage area 9.

[0059] like Figure 3As shown, the conveying and lifting device 2 includes a conveying and lifting structure installed on the conveying frame 10. The conveying and lifting structure is connected to a conveying and lifting frame 21. The conveying and lifting frame 21 is provided with a lifting conveyor belt 22 for conveying direction adjustment. The conveying and lifting frame 21 is provided with a lifting limit sensor 24. The conveying and lifting frame 21 is also provided with a lifting limit cylinder 23. The lifting limit cylinder 23 is connected to a lifting limit block 25.

[0060] The specific operation of the conveyor lifting device 2 is as follows: When the material tray box 12 enters the lifting conveyor belt 22, the conveyor lifting structure drives the conveyor lifting frame 21 to rise, so that the lifting conveyor belt 22 is flush with the delivery conveyor belt 14. Then, the lifting conveyor belt 22 drives the material tray box 12 away from the delivery conveyor belt 14 until the lifting limit sensor 24 generates a sensing signal and stops the conveying of the lifting conveyor belt 22. Then, the lifting limit cylinder 23 drives the lifting limit block 25 to limit the material tray box 12, ensuring that the position of the material tray box 12 is accurately aligned with the handling and transfer device 3. After all the material trays are removed, the lifting conveyor belt 22 reverses the transport and transfer to deliver the empty boxes to the delivery conveyor belt 14.

[0061] like Figure 4-5 As shown, the conveying and transferring device 3 includes a transfer frame 30 mounted on a machine frame. A clamping assembly 31 is connected to the transfer frame 30 via a transfer movable structure. The transfer movable structure drives the clamping assembly 31 to move vertically and horizontally. The clamping assembly 31 includes a clamping lifting seat 303. A downward-facing laser rangefinder sensor 301 and a positioning pin 307 that mates with the center hole of the material tray are located on the lower part of the clamping lifting seat 303. A vertically oriented brush-pushing cylinder 302 is also mounted on the clamping lifting seat 303. The brush-pushing cylinder 302 is connected to a swing arm rack 304. Two swing arm gears that mesh with the swing arm rack 304 are mounted on the clamping lifting seat 303. A brush swing arm 305 is fixedly connected to a gear. The other end of the brush swing arm 305 is connected to a round brush 306 for gripping the material tray. The transfer mechanism includes a transfer transverse motor 36 and a transfer transverse seat 37 driven by the transfer transverse motor 36, which is mounted on the transfer frame 30. A gripping rotary seat is connected to the transfer transverse seat 37 via a gripping rotary motor 35. A gripping lifting guide rail 33 is mounted on the gripping rotary seat. A gripping lifting rack 32 is fitted on the gripping lifting guide rail 33. The gripping lifting rack 32 is fitted with a gripping lifting gear, which is driven by a gripping lifting motor 34. The gripping lifting seat 303 is connected to the lower end of the gripping lifting rack 32.

[0062] The specific operation of the transfer is as follows: First, adjust the distance sensed by the laser rangefinder 301 according to the size of the tray. Then, the clamping lifting motor 34 drives the clamping lifting gear to rotate, which in turn drives the clamping lifting rack 32 to descend along the clamping lifting guide rail 33 until the measured distance set by the laser rangefinder 301 (the target of the distance measurement is the frame panel) is reached, and the descent stops. At this time, the height of the positioning pin 307 matches the height of the center hole of the tray in the tray box 12. Then, the transfer transverse motor 36 drives the transfer transverse seat 37 to move, so that the positioning pin 307 is inserted into the center hole of the tray. Finally, the brush push cylinder 302 drives the swing arm gear. The movement of bar 304 causes the two brush arms 305 to rotate, thereby causing the two round brushes 306 to clamp the tray. Then, the transfer transverse motor 36 drives the transfer transverse seat 37 to move, thus transporting the clamped tray to the tray flipping device 4. Depending on the size of the tray, to avoid interference between the tray flipping device 4 and the round brushes 306, the clamping rotary motor 35 drives the clamping rotary seat and clamping assembly 31 to rotate as a whole. This allows the part not clamped by the round brushes 306 to cooperate with the tray flipping device 4. Then, the tray flipping device 4 clamps the tray, and the conveying device 3 repeats the above conveying operation.

[0063] like Figure 9 As shown, the material tray flipping device 4 includes a flipping and lifting structure 62 mounted on the frame. A flipping mounting base 61 extending through the frame panel is connected to the flipping and lifting structure 62. A first flipping motor 63 with a vertically oriented rotating shaft is mounted on the flipping mounting base 61. The first flipping motor 63 is connected to a first flipping seat 64. A flipping movable motor 65 is mounted on the first flipping seat 64. The flipping movable motor 65 is connected to a flipping gear. A flipping movable block 66 is mounted on the first flipping seat via a slide rail. A flipping rack that cooperates with the flipping gear is mounted on the flipping movable block 66. A second flipping motor 67 with a horizontally oriented rotating shaft is mounted on the flipping movable block 66. A flipping clamp 68 for clamping the material tray is connected to the second flipping motor 67.

[0064] In practical use, when the material tray is transported by the conveying device, the rotating gear is driven by the rotating motor 65 according to the size of the material tray, so that the rotating block 66 can move. Then, the rotating clamp 68 clamps the transported material tray and identifies it. If the information is correct, the first rotating motor 63 rotates 180 degrees and the second rotating motor 67 rotates 90 degrees, thus completing the flipping and repositioning of the material tray from vertical to horizontal, and entering the lead-finding station. Then, the material tray is placed on the panel of the frame. To avoid interference, a slot with a width smaller than the diameter of the material tray is opened on the panel. If the information is incorrect, the first rotating motor 63 rotates 90 degrees and the second rotating motor 67 rotates 90 degrees, thus completing the flipping and repositioning of the material tray from vertical to horizontal. Then, the rotating lifting structure 62 drives the rotating mounting base 61 to descend as a whole, so that the material tray is placed on the incorrect material tray storage rack 5.

[0065] like Figure 6-7 As shown, the lead-finding conveying mechanism 6 includes a material tray unwinding device 42 mounted on the frame and a material tray pushing structure 41 that pushes the material tray, which is placed flat by the material tray flipping device 4, to the material tray unwinding device 42. The frame is equipped with two parallel lead-finding sensors 44 and a lead-finding air blowing block 43 that blows the lead-finding strip unwound by the material tray unwinding device into the lead-finding sensors. The signals from the two lead-finding sensors 44 are used to control the unwinding and rewinding of the material tray unwinding device 42. The frame is also equipped with a clamping conveying device 46 for transporting the material tray on the material tray unwinding device 42 to the tape-attaching turntable device, and the clamping conveying device 46 clamps the lead-finding strip unwound from the material tray during transport.

[0066] The specific operation of the lead-finding device is as follows: First, the material tray is placed on the panel of the frame by the material tray flipping device 4. Then, the material tray is pushed onto the material tray unwinding device 42 by the material tray pushing structure 41. Then, the material tray is rotated by the material tray unwinding device 42 to unwind. At the same time as unwinding, the lead-finding air blowing block 43 blows out airflow, which blows the lead of the material tray into the two parallel lead-finding sensors 44 (laser beam sensors) until both lead-finding sensors generate a sensing signal (laser beam is blocked and cannot be connected). After receiving a laser signal (indicating the generation of a sensing signal), the unwinding stops, and then the winding continues until one of the lead-finding sensors has no sensing signal and the other leads-finding sensor generates a sensing signal, stopping the unwinding device. Each reel is unwound in this manner, ensuring that the unwound lead is between the two lead-finding sensors 44, thus achieving lead-finding positioning. Then, the lead of the reel is clamped by the clamping and conveying device 46, and the reel is transported to the tape-applying turntable device 7 for subsequent protective tape application.

[0067] like Figure 10-11As shown, the clamping and conveying device 46 includes a clamping and conveying seat 71 mounted on the frame. The clamping and conveying seat 71 has a clamping and conveying movable structure 72 that can move horizontally and vertically. A clamping and conveying movable base 73 is mounted on the clamping and conveying movable structure 72. Two conveying chucks 74 are mounted on the clamping and conveying movable base 73, and the distance between the centers of the two conveying chucks 74 is the distance between the centers of the tape-attaching turntable device 7 and the material tray unwinding device 42. Two clamping swing arms 77 are sleeved on the main body rod of the conveying chuck 74 closest to the material tray unwinding device 42. Both 77 are connected to the first swing arm motor 75 and the second swing arm motor 76 on the clamping and conveying movable seat 73 via a transmission structure. Both clamping swing arms 77 are connected to clamping blocks 78 for clamping the tape head of the material tray. An arc-shaped clamping groove is provided on the frame panel with the rotation center of the material tray unwinding device as the center. When clamping the tape head, the clamping block is inserted into the clamping groove and moves in the clamping groove to complete the clamping of the tape head. The clamping and conveying movable seat 73 is provided with two vertically oriented pressure plate cylinders 79 that are symmetrical about the conveying clamp 74 near the material tray unwinding device. Both pressure plate cylinders 79 are connected to pressure plate blocks 80.

[0068] The specific operation of the clamping and conveying device 46 is as follows: First, the clamping and conveying movable structure 72 drives the clamping and conveying movable seat 73 to move up and down and horizontally, so that the clamping block 78 can be inserted into the clamping groove 45. At this time, there is still a gap between the conveying clamp 74 and the material tray. Then, the pressing plate cylinder 79 drives the pressing plate block 80 to descend, so that the pressing plate block 80 presses down on the material tray. Then, the clamping and conveying movable structure drives the clamping and conveying movable seat 73 to continue to descend, so that the conveying clamp 74 clamps the material tray. During this process, the pressing plate cylinder 79 will retract, and the pressing plate block 80 will remain relatively stationary. Then, the first swing arm motor 75 and the second swing arm motor 76 drive the clamping swing arm 77 to rotate, so that the clamping block 78 completes the clamping of the tape head. Then, the clamping and conveying movable structure 72 drives the clamping movable seat 73 to move as a whole, moving the material tray to the tape-attaching turntable device 7.

[0069] like Figure 8 As shown, the unwinding device 42 includes an unwinding seat 51 mounted on the frame. An unwinding shaft 54 ​​is connected to the unwinding seat 51 via a vertically oriented unwinding lifting cylinder 56. The unwinding shaft 54 ​​can rotate relative to the unwinding lifting cylinder 56. The unwinding shaft 56 is connected to an unwinding rotating motor 52 via an unwinding transmission structure 53. The unwinding transmission structure 53 and the unwinding shaft 54 ​​can lift and lower each other but cannot rotate relative to each other. An unwinding disc 57 for supporting the material tray is fixedly sleeved on the upper part of the unwinding shaft 54.

[0070] When the material tray is pushed to the material tray unwinding device 42 by the material tray pushing structure 41, the unwinding lifting cylinder 56 first drives the unwinding shaft 54 ​​and the unwinding reel 57 to rise as a whole, so that the upper part of the unwinding shaft 54 ​​passes through the material tray, and the material tray is supported by the unwinding reel 57. Then, the unwinding motor 52 is started, and the unwinding transmission structure 53 drives the unwinding shaft 54 ​​to rotate, thereby realizing unwinding and rewinding. The air blowing and sensing of the lead seeker are used to realize lead seeker.
