Description

Technical Field

[0001] This utility model relates to the field of insertion machines, and in particular to a straight feeding mechanism and a corresponding horizontal automatic component insertion machine. Background Technology

[0002] Current component insertion machines generally consist of an insertion mechanism, a feeding mechanism, and a conveying mechanism. In most cases, the feeding mechanism and insertion mechanism are designed separately, with a chain-type conveying mechanism connecting them for transporting electronic components. In existing technology, the conveying mechanism of the insertion machine is divided into multiple conveying sections. These sections are positioned differently, and the tortuous connections between them lead to large cumulative transmission errors. This results in issues such as component deviation, jamming, uneven conveying, and instability during transport, ultimately impacting work efficiency.

[0003] Therefore, it is necessary to provide a horizontal automatic component insertion machine to solve the above-mentioned technical problems. Utility Model Content

[0004] This utility model provides a horizontal automatic component insertion machine to solve the problems of feeding mechanism deviation, jamming, uneven conveying, unstable conveying, and reduced work efficiency in the existing insertion machine.

[0005] To solve the above-mentioned technical problems, the technical solution of this utility model is: a straight feeding mechanism for conveying electronic components output from the unloading mechanism to the insertion mechanism, the straight feeding mechanism comprising:

[0009] A conveying drive mechanism is fixedly connected to the flat frame, and the output end of the conveying drive mechanism is connected to one of the guide sprockets.

[0010] In this utility model, the insertion mechanism includes an insertion frame, the unloading mechanism includes an unloading frame, and the flat feeding mechanism further includes a vertical guide groove rod disposed on the flat frame, and a first transverse guide groove rod and a second transverse guide groove rod perpendicular to the vertical guide groove rod. Each of the vertical guide groove rod, the first transverse guide groove rod and the second transverse guide groove rod is provided with a guide groove for guiding the movement of the conveyor chain and a guide plate for directional engagement with the mating groove on the double hook chain clamp.

[0011] The first transverse guide bar and the second transverse guide bar are arranged in parallel, with the first transverse guide bar located above the second transverse guide bar. The two ends of the first transverse guide bar are respectively connected to the insertion machine frame and the unloading machine frame. One end of the second transverse guide bar is connected to the unloading machine frame. The vertical guide bar is connected to the insertion machine frame. One end of the vertical guide bar is connected to the first transverse guide bar, and the other end of the vertical guide bar is connected to the second transverse guide bar.

[0012] The flat feeding mechanism further includes a tensioning frame and a tensioning mechanism. The tensioning frame is disposed between the vertical guide rail and the second horizontal guide rail. The tensioning mechanism includes a tensioning rod that is elastically rotatably disposed on the tensioning frame and a tensioning sprocket that is rotatably disposed on the tensioning rod. The tensioning sprocket is driven and engaged on the inner side of the conveyor chain.

[0013] Furthermore, guide sprockets are provided at the ends of the first and second transverse guide rods away from the insertion mechanism, between the vertical guide rod and the first transverse guide rod, between the vertical guide rod and the tensioning mechanism, and between the tensioning mechanism and the second transverse guide rod.

[0014] In this utility model, the top side of the tensioning rod is rotatably connected to the tensioning frame, the bottom side of the tensioning rod is rotatably connected to the tensioning sprocket, the middle part of the tensioning rod is elastically connected to the tensioning frame through a tension spring, and the conveying chain passes sequentially through the bottom of the tensioning sprocket and the top of the guide sprocket to extend into the second transverse guide groove rod.

[0015] In this utility model, the flat feeding mechanism further includes a pressure roller, which is rotatably connected to the flat frame through a wheel axle. The pressure roller is located at the top of the first transverse guide rod near the insertion mechanism and is located above the moving trajectory of the double hook chain clamp, thus providing a moving guide for the double hook chain clamp.

[0016] In this utility model, the straight feeding mechanism further includes an upper waste foot removal mechanism, which includes an upper waste foot removal cylinder, a waste scraping rod, an upper guide trough, and an upper air nozzle;

[0017] The scraper bar is connected to the output end of the upper waste removal cylinder. Both the scraper bar and the upper waste removal cylinder are located below the first transverse guide bar. The scraper bar is opposite to the movement trajectory of the electronic components. The upper guide groove is located below the upper waste removal cylinder. The upper air nozzle is connected to the corresponding air blowing device. The upper air nozzle is located above the first transverse guide bar and opposite to the scraper bar.

[0018] In addition, the flat feeding mechanism also includes a lower waste foot removal mechanism, which includes a lower waste foot removal cylinder, an extrusion block, and a lower guide chute.

[0019] The extrusion block is connected to the output end of the lower waste removal cylinder. Both the extrusion block and the lower waste removal cylinder are located above the second transverse guide bar.

[0021] This utility model also includes a horizontal automatic component insertion machine, which uses the above-mentioned straight feeding mechanism.

[0022] Compared with the prior art, the advantages of this utility model are as follows: The flat feeding mechanism of this utility model directly connects the insertion mechanism and the unloading mechanism by setting a flat frame. The conveyor chain is set along the flat frame, which makes the conveyor chain have less bending structure, reduces the number of guide sprockets, makes the conveying smoother and more stable, and reduces the occurrence of deviation and jamming, resulting in high working efficiency. Furthermore, the conveyor chain is shorter, and the distance between the unloading mechanism and the insertion mechanism is closer, reducing the overall width of the insertion machine, making the structure of the insertion machine more compact and the overall size smaller.

[0023] In addition, since a circular conveyor chain is used to directly transport electronic components between the insertion mechanism and the unloading mechanism, when the insertion of an electronic component at a specific position fails, the conveyor chain can drive the double hook chain clamp at that specific position back to the corresponding unloading mechanism for replacement. The electronic components that have not been inserted can be kept clamped on the double hook chain clamp without falling off, thus achieving automatic and rapid replacement.

[0033] The terms "first" and "second" in this utility model are used for descriptive purposes only and should not be construed as indicating or implying relative importance, nor as a restriction on the order of events.

[0036] The following is a preferred embodiment of a horizontal automatic component insertion machine provided by this utility model, which can solve the above-mentioned technical problems.

[0037] Please refer to Figure 1 and Figure 2 ,in Figure 1 This is a schematic diagram of the structure of the horizontal automatic component insertion machine of this utility model. Figure 2 This is a schematic diagram of the straight feeding mechanism and unloading station of this utility model.

[0038] In the diagram, units with similar structures are represented by the same labels.

[0039] This embodiment provides a horizontal automatic component insertion machine, which includes a feeding mechanism 11, an insertion mechanism 12, and a straight feeding mechanism.

[0040] The flat feeding mechanism is used to transport the electronic components output by the unloading mechanism 11 to the insertion mechanism 12. The insertion mechanism 12 performs lead trimming and insertion operations on the electronic components transported by the flat feeding mechanism. The flat feeding mechanism includes a flat frame 13, a conveyor chain 14, a double hook chain clamp 141, and a conveyor drive mechanism 15.

[0041] One end of the flat frame 13 is located below the feeding mechanism 11, and the other end is connected to the insertion mechanism 12. Multiple guide sprockets 131 are provided on the flat frame 13.

[0042] The inner side of the conveyor chain 14 is connected to the guide sprocket 131 to form a closed loop structure, and the two conveyor chains 14 are arranged in parallel. The double hook chain clamp 141 is set on the side of the two conveyor chains 14 that are close to each other. The two ends of the electronic components are clamped one-to-one on the double hook chain clamp 141 of the two conveyor chains 14 to achieve stable conveying.

[0043] Please refer to Figure 3 It should be noted that the double hook chain clamp 141 is elastically rotatably equipped with a chain clamping plate 1411. The two chain clamping plates 1411 clamp the electronic components on the double hook chain clamp 141 through elastic force. The arc-shaped pressure surface at the bottom of the chain clamping plate 1411 can be squeezed to overcome the elastic force and make the chain clamping plate 1411 release the clamping of the electronic components.

[0044] The conveying drive mechanism 15 is fixedly connected to the flat frame 13. The output end of the conveying drive mechanism 15 is connected to a guide sprocket 131, thereby driving the two conveying chains 14 to rotate in a cycle.

[0045] Please refer to Figure 1 In this embodiment, the insertion mechanism 12 includes an insertion frame 121, and the unloading mechanism 11 includes an unloading frame 111.

[0046] Please refer to Figure 2 and Figure 5 The flat feeding mechanism in this embodiment also includes a vertical guide rod 134 disposed on the flat frame 13, and a first transverse guide rod 132 and a second transverse guide rod 133 perpendicular to the vertical guide rod 134.

[0047] Each of the vertical guide rail 134, the first transverse guide rail 132, and the second transverse guide rail 133 has a guide groove on one side for guiding the movement of the conveyor chain 14, and a guide plate for directional engagement with the mating groove on the double hook chain clamp 141. (Please refer to the diagram for the guide groove.) Figure 5 The guide groove 1321 on one side of the first transverse guide rod 132, and the guide plate are shown in the figure. Figure 5 Guide plate 1322 on one side of the first transverse guide rod 132.

[0048] Please refer to Figure 3 The double hook chain clamp 141 is provided with a roller or bearing 1412 for contacting the guide plate 1322 in the mating groove. The mating of the guide groove with the conveyor chain 14 and the mating of the guide plate 1322 with the double hook chain clamp 141 enable the double hook chain clamp 141 to move stably in a cycle with the conveyor chain 14.

[0049] Please refer to Figure 2 In this embodiment, the first transverse guide rod 132 and the second transverse guide rod 133 are arranged in parallel. The first transverse guide rod 132 is located above the second transverse guide rod 133. The two ends of the first transverse guide rod are connected to the insertion frame 121 and the unloading frame 111, respectively. One end of the second transverse guide rod is connected to the unloading frame 111. The vertical guide rod 134 is connected to the insertion frame 121. One end of the vertical guide rod 134 is connected to the first transverse guide rod 132, and the other end of the vertical guide rod 134 is connected to the second transverse guide rod 133.

[0050] Please refer to Figure 2 and Figure 4 The flat feeding mechanism also includes a tensioning frame 161 and a tensioning mechanism. The tensioning frame 161 is disposed between the vertical guide rail 134 and the second horizontal guide rail 133. The tensioning mechanism includes a tensioning rod 162 that is elastically rotatably disposed on the tensioning frame 161 and a tensioning sprocket 163 that is rotatably disposed on the tensioning rod 162. The tensioning sprocket 163 is driven and engaged on the inner side of the conveyor chain 14.

[0051] Please refer to Figure 2 More specifically, guide sprockets 131 are provided at the ends of the first transverse guide rod 132 and the second transverse guide rod 133 that are away from the insertion mechanism 12, between the vertical guide rod 134 and the first transverse guide rod 132, between the vertical guide rod 134 and the tensioning mechanism, and between the tensioning mechanism and the second transverse guide rod 133.

[0052] The conveyor chain 14 can stably circulate along the vertical guide rail 134, the first transverse guide rail 132, and the second transverse guide rail 133. This results in a less curved structure in the conveyor chain. At the same time, the tensioning effect of the tension sprocket 163 on the conveyor chain 14 allows for smoother and more stable circulatory conveying, reducing the likelihood of deviation or jamming, and improving work efficiency.

[0053] Please refer to Figure 4 In this embodiment, the tensioning frame 161 has a frame structure, and two sets of tensioning mechanisms are arranged inside the tensioning frame 161. The top side of the tensioning rod 162 is rotatably connected to the tensioning frame 161, and the bottom side of the tensioning rod 162 is rotatably connected to the tensioning sprocket 163. The middle part of the tensioning rod 162 is elastically connected to the tensioning frame 161 through a tension spring 164. The conveyor chain 14 passes sequentially through the bottom of the tensioning sprocket 163 and the top of the guide sprocket 131, extending into the second transverse guide rod 133.

[0054] Please refer to Figure 2 and Figure 5 In this embodiment, the flat feeding mechanism also includes a pressure roller 135. The pressure roller 125 is rotatably connected to the flat frame 13 via a wheel axle. The pressure roller 135 is located at the top of the first transverse guide rod 132 near the insertion mechanism 12. The pressure roller 135 is located above the moving trajectory of the double hook chain clamp 141 and is used to guide the movement of the double hook chain clamp 141 to ensure the stable movement of the double hook chain clamp 141.

[0055] Please refer to Figure 5 and Figure 6In this embodiment, the flat feeding mechanism also includes an upper waste removal mechanism. It should be noted that a detection sensor can be installed on the flat frame 13 to detect defective electronic components. The upper waste removal mechanism then removes the defective electronic components from the double-hook chain clamp 141. Alternatively, if the insertion mechanism 12 fails to insert components, the double-hook chain clamp 141 for replenishing electronic components is moved to the position of the upper waste removal mechanism, where the waste electronic components on the double-hook chain clamp 141 are removed by the upper waste removal mechanism.

[0056] Specifically, the upper waste removal mechanism includes an upper waste removal cylinder 174, a waste scraper 175, an upper guide chute 179, and an upper air nozzle 176.

[0057] The scraper bar 175 is connected to the output end of the upper scrap removal cylinder 174. Both the scraper bar 175 and the upper scrap removal cylinder 174 are located below the first transverse guide rod 132. The scraper bar 175 is aligned with the movement trajectory of the electronic components. The upper guide trough 179 is located below the upper scrap removal cylinder 174. The upper air nozzle 176 is connected to a corresponding air blowing device. The upper air nozzle 176 is located above the first transverse guide rod 132 and opposite to the scraper bar 175. The upper scrap removal cylinder 174 drives the scraper bar 175 to move upward to squeeze the electronic component waste. Combined with the air blowing from the upper air nozzle 176, the electronic component waste falls smoothly into the upper guide trough 179.

[0058] In addition, the flat feeding mechanism also includes a lower waste foot removal mechanism. After insertion, the pins left on the double hook chain clamp 141 can be removed by the lower waste foot removal mechanism.

[0059] The lower waste removal mechanism includes a lower waste removal cylinder 177, an extrusion block 178, and a lower guide chute 172.

[0060] The extrusion block 178 is connected to the output end of the lower waste removal cylinder 177. Both the extrusion block 178 and the lower waste removal cylinder 177 are located above the second transverse guide rod 133. The extrusion block 178 is opposite to the moving trajectory of the double hook chain clamp 141. The extrusion block 178 is used to extrude the chain clamping plate 1411 of the double hook chain clamp 141, so that the chain clamping plate 1411 overcomes the elastic force and releases the clamping of the electronic components. The lower guide groove 172 is located below the second transverse guide rod 133 and opposite to the extrusion block 178. After the chain clamping plate 1411 is opened, the lead waste falls into the lower guide groove 172.

[0061] Please refer to Figure 2 , Figure 5 and Figure 6The upper guide chute 179 and the lower guide chute 172 are both equipped with inlet ports at their tops and outlet ports at their bottoms. The outlet port of the upper guide chute 179 is connected to the inlet port of the lower guide chute 172. The straight feeding mechanism also includes a waste material guide plate 173 and a waste material collection box 171. The waste material guide plate 173 is inclined and positioned below the lower guide chute 172, with the waste material collection box 171 located at the lower end of the waste material guide plate 173. The waste material flows from both the upper guide chute 179 and the lower guide chute 172 into the waste material collection box 171 via the waste material guide plate 173.

[0062] The working principle of this utility model is as follows: The conveyor chain 14 carries the double hook chain clamp 141 and circulates between the feeding mechanism 11 and the insertion mechanism 12 to receive the electronic components output by the feeding mechanism 11 and transport them to the insertion mechanism 12 for lead cutting and insertion.

[0063] Among them, the double hook chain clamp 141 moves with the conveyor chain 14 to the chain clamp opening mechanism section below the unloading station. The squeezing component of the chain clamp opening mechanism section will squeeze the arc-shaped pressure surface of the double hook chain clamp 141, so that the two chain clamp pressure plates 1411 open, and the double hook chain clamp 141 at a specific position goes to the unloading station for precise unloading.

[0064] Then, the double-hook chain clamp 141 continues to move with the conveyor chain 14, and the electronic components are conveyed to the centering mechanism to achieve electronic component centering. After the arc-shaped pressure surface of the double-hook chain clamp 141 is released from the compression of the extrusion component, under the elastic force of the elastic element, the two chain clamp plates 1411 clamp the electronic components on the double-hook chain clamp 141 from different sides of the electronic components.

[0065] The conveyor chain 14 moves stably within the guide grooves of the vertical guide rod 134, the first horizontal guide rod 132, and the second horizontal guide rod 133. The guide plate 132 limits the movement of the double hook chain clamp 141. The tension sprocket 163 tensions the conveyor chain 14, ensuring smooth and stable cyclic conveying of electronic components with precise delivery and minimizing the risk of deviation or jamming.

[0066] In addition, when a component fails to be inserted and a replacement electronic component is needed, the detector detects the need for replacement, the conveyor chain reverses its rotation, and the corresponding double hook chain clamp 141 moves to the position of the upper waste removal mechanism. The upper waste removal mechanism squeezes and removes the waste electronic component on the specific double hook chain clamp 141. The specific double hook chain clamp 141 then moves to the bottom of the unloading station to receive a new electronic component. After that, the conveyor chain starts to rotate in the forward direction again, and the double hook chain clamp 141 moves back to the insertion mechanism 12 to perform the lead-cutting insertion work.

[0067] After the insert is completed, the cut material foot will remain on the double hook chain clamp 141. The remaining pin on the double hook chain clamp 141 will be removed when the double hook chain clamp 141 moves to the lower waste material foot removal mechanism, thus realizing the dropping of the material foot and forming a complete closed-loop conveying process of the conveyor chain.

[0068] This completes the process of feeding and inserting electronic components and removing waste parts by the horizontal automatic component insertion machine in this embodiment.

[0069] In this preferred embodiment, the conveyor chain of the horizontal automatic component insertion machine circulates between the feeding mechanism and the insertion mechanism. The double hook chain clamps open only when they are below the feeding mechanism, and remain closed at other positions, enabling automatic component insertion with high efficiency and low cost.

[0070] Meanwhile, the straight feeding mechanism directly connects the insertion mechanism and the unloading mechanism through a straight frame. The conveyor chain is set along the straight frame, which results in a less curved structure in the conveyor chain, reduces the number of guide sprockets, and makes the conveying smoother and more stable, reducing the likelihood of deviation and jamming, thus increasing work efficiency. Furthermore, the shorter conveyor chain and the closer distance between the unloading mechanism and the insertion mechanism reduce the overall width of the insertion machine, making its structure more compact and its overall size smaller.

[0071] In addition, since a circular conveyor chain is used to directly transport electronic components between the insertion mechanism and the unloading mechanism, when the insertion of an electronic component at a specific position fails, the conveyor chain can drive the double hook chain clamp at that specific position back to the corresponding unloading mechanism for replacement. The electronic components that have not been inserted can be kept clamped on the double hook chain clamp without falling off, thus achieving automatic and rapid replacement.

[0072] In summary, although the present invention has been disclosed above with reference to preferred embodiments, the above preferred embodiments are not intended to limit the present invention. Those skilled in the art can make various modifications and refinements without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be determined by the scope defined in the claims.
