Description

Technical Field

[0001] The present application relates to the technical field of automobile parts processing, and in particular to an automatic assembly device for arc-extinguishing plates. Background Art

[0002] The development trend of new energy vehicles is becoming increasingly stronger. New energy vehicles refer to vehicles that use unconventional automotive fuels as their power source and integrate advanced technologies in vehicle power control and driving to form vehicles with advanced technical principles, new technologies and new structures.

[0003] Existing new energy vehicles are usually mainly electric vehicles. Various types of electronic components are indispensable in electric vehicles. In order to ensure the normal operation between various electronic components and reduce the arcing effect caused by high-voltage current, it is usually necessary to set an arc extinguishing structure at the switch part to reduce the generation of arcing. Therefore, arc extinguishing sheets are indispensable components.

[0004] Reference Figure 5 In the process of assembling arc-extinguishing plates, existing automobile parts manufacturers know that the arc-extinguishing plates include a substrate, two first slots 58 are opened on one side edge of the substrate, and a second slot 59 is opened on the other side edge of the substrate, and protrusions 60 are formed in the first slot 58 and the second slot 59.

[0005] Reference Figure 5 In actual use, ten arc-extinguishing plates need to be stacked at intervals, and are respectively clamped in the first slot 58 and the second slot 59 through red steel paper. The protrusion 60 passes through the red steel paper, so that the red steel paper is clamped and fixed in the first slot 58 and the second slot 59, thereby realizing that every ten arc-extinguishing plates form an arc-extinguishing unit.

[0006] Reference Figure 5 In the existing production process, manual assembly is usually performed by humans wearing finger gloves. After the ten arc-extinguishing plates are stacked and assembled, a punching die head is needed to knock on the red steel paper so that the protrusion 60 passes through the red steel paper to ensure that the ten arc-extinguishing plates are connected as one through the clamping of the red steel paper.

[0007] Regarding the above-mentioned related technologies, the inventors believe that since the size of the arc extinguishing plates is small and ten arc extinguishing plates are required to assemble each arc extinguishing unit, assembling a complete arc extinguishing unit is time-consuming, and manual assembly is prone to errors and inefficient. Summary of the Invention

[0008] In order to improve the assembly efficiency of arc-extinguishing plates and enhance the assembly quality of products, the present application provides an automatic assembly device for arc-extinguishing plates.

[0009] The present application provides an automatic assembly device for arc-extinguishing plates, which adopts the following technical solutions:

[0010] A kind of automatic assembly equipment of arc extinguishing plates, including a mounting table, a rectangular track connected end to end is provided on the table surface of the mounting table, a plurality of mold bases for stacking arc extinguishing plates at intervals slide in the rectangular track, a push rod assembly is provided on the mounting table for pushing the mold base to move in a direction in the rectangular track, and the push rod assembly can push the mold base to move in a circular motion in the rectangular track, and the mounting table is also provided with a feeding assembly for quantitatively filling arc extinguishing plates into the mold base, a press-fit assembly for cutting red steel paper and squeezing it onto a protrusion, and a blanking assembly for pushing the arc extinguishing unit out of the mold base. The feeding assembly, press-fit assembly and blanking assembly are arranged in sequence along the moving track of the mold base.

[0011] By adopting the above technical solution, a corresponding number of arc-extinguishing plates are inserted into the die base through the feeding component, and then the die base is pushed to move in the rectangular track through the push rod component. During the movement of the die base, the red steel paper is pre-rolled through the press-fitting component, and the red steel paper of the required length is cut out. Finally, the cut red steel paper is pressed on the protrusion of the arc-extinguishing plate, so that ten arc-extinguishing plates are connected and assembled into an arc-extinguishing unit through the red steel paper. The formed arc-extinguishing unit is pushed out of the die base under the action of the blanking component. During the whole process, the die base moves cyclically in the inner cavity of the rectangular track, thereby realizing uninterrupted forming of the arc-extinguishing unit. Automated assembly is realized in the entire assembly process, which overcomes the defect of easy error in manual assembly and ensures the production quality of the product.

[0012] Optionally, the mold base includes a moving block sliding in a rectangular track, a stopper arranged on the moving block, and several partitions fixed on the side walls of the stopper, wherein the several partitions are evenly spaced along the vertical direction, and an accommodating cavity for plugging in the arc extinguishing plate is formed between two adjacent partitions, the width of the partition is smaller than the distance between the first card slot and the second card slot, and the stopper is located on one side of the accommodating cavity and is provided with a card slot for plugging in the end of the arc extinguishing plate.

[0013] By adopting the above technical solution, during actual use, the arc extinguishing piece is pushed into the corresponding accommodating cavity, and the arc extinguishing piece is inserted into the clamping groove to realize the positioning of a single arc extinguishing piece. The number of accommodating cavities is set to ten, until the ten accommodating cavities in a single mold base are filled, so that the ten arc extinguishing pieces constitute an arc extinguishing unit.

[0014] Optionally, the push rod assembly includes a first cylinder fixed on the upper surface of the mounting table, and a push column coaxially fixed on the telescopic rod of the first cylinder for pushing the mold base to move. The first cylinder is set to four, and the four first cylinders are respectively fixed at the four corners of the rectangular track, and the sliding direction of two adjacent push columns is set vertically.

[0015] By adopting the above technical solution, a gap with the width of two mold bases is reserved in the rectangular track. Each time the mold base is pushed to move in the inner cavity of the rectangular track, the piston rods of the two diagonally arranged first cylinders are extended, thereby pushing several mold bases to move in the inner cavity of the rectangular track.

[0016] Optionally, the feeding assembly includes a vibrating plate fixed on the mounting platform, a discharge track fixed on the discharge port of the vibrating plate, a plurality of vertically arranged collecting channels fixed on the mounting platform, and a pushing component arranged on the mounting platform for pushing the arc extinguishing sheets in different collecting channels into the accommodating cavity. The discharge track is inclined, and the discharge port of the discharge track is located at the upper end opening of the collecting channel. The cross-sectional shape of the inner cavity of the collecting channel is the same as the shape of the arc extinguishing sheet.

[0017] By adopting the above technical solution, the preferred vibration disk and pushing components are set into two groups, a single feeding track is set into five material channels, and each vibration disk is provided with five discharge ports, so that one vibration disk can feed five aggregate channels at the same time. The total number of aggregate channels is set to ten, and the ten aggregate channels are arranged side by side. During the vibration of the vibration disk, since the feeding track is inclined, the effect of conveying arc extinguishing plates into the corresponding aggregate channels is achieved.

[0018] Optionally, the pushing component includes a second cylinder fixed on the upper surface of the mounting table, a mounting block fixed at the end of the piston rod of the second cylinder, and plug plates evenly spaced on the side of the mounting block facing the track. The number of the collection channels is equal to the number of the plug plates. The collection channels are provided with plug holes for use with the plug plates on the side facing the rectangular track, and the heights of several of the plug plates gradually increase along the length direction of the mounting block.

[0019] By adopting the above technical solution, since ten arc-extinguishing plates need to be arranged at intervals when the arc-extinguishing plates are assembled into an arc-extinguishing unit, in order to facilitate the assembly of the ten arc-extinguishing plates, the pushing components are arranged into two groups, and the mounting block height of one group is higher than the other mounting block, so that the arc-extinguishing plates in the aggregate channel are pushed into the corresponding accommodating cavities by the insert plate. Since the pushing components are arranged into two groups, when a single mold base moves to the first mounting block position, the five arc-extinguishing plates on the bottom layer are pushed into the corresponding accommodating cavities in advance. When the mold base moves to the second mounting block, the five accommodating cavities in the upper half of the mold base are filled, and finally the ten arc-extinguishing plates are pressed into the mold group.

[0020] Optionally, the press-fit assembly includes a base fixed on the mounting table, two pressure blocks sliding on the base, a cutter slidingly arranged on the pressure block, a first driving component arranged on the base for driving the two pressure blocks to slide toward each other synchronously, a second driving component arranged on the pressure block to drive the two groups of cutters to slide toward each other synchronously, and an unwinding component arranged on the base for unwinding red steel paper. The base is hollow, the rectangular track passes through the base, and the two pressure blocks are respectively located on both sides of the rectangular track.

[0021] By adopting the above technical solution, when the mold base slides along the inner cavity of the rectangular track until a single mold base is located in the inner cavity of the base, the first driving component causes the two pressure blocks to slide toward each other synchronously, so that the two pressure blocks clamp the mold base. At the same time, under the action of the second driving component, when the red steel paper is clamped on the protrusion, the cutter cuts the red steel paper, thereby facilitating the assembly of the arc extinguishing sheet on the next mold base.

[0022] Optionally, the first driving component includes a first rack sliding in the inner cavity of the base, a second rack sliding in the inner cavity of the base, a gear rotatably connected to the inner cavity of the base, and a third cylinder fixed to the outside of the base, the first rack is fixedly connected to one of the pressure blocks, the second rack is fixedly connected to the other pressure block, the first rack and the second rack are arranged opposite to each other, and the first rack and the second rack are both engaged with the gear, and the telescopic rod of the third cylinder extends into the inner cavity of the base and is fixedly connected to the first rack.

[0023] By adopting the above technical solution, the piston rod of the third cylinder is driven to extend, so that the first rack and the second rack slide toward each other synchronously under the action of the gear, so that the two pressing blocks approach the mold base synchronously until the red steel paper is pressed against the corresponding raised parts.

[0024] Optionally, the second driving component is provided with three groups, one of which is provided on one of the pressure blocks, and the other two groups are provided on the other pressure block. The second driving component includes a plurality of push rods sliding on the pressure block, a first block sliding horizontally on the mounting block, a second block sliding vertically on the mounting block, and a third block sliding horizontally on the mounting block. The pressure block is provided with a first groove for sliding of the push rod on the side facing the rectangular track, and a second groove for sliding of the third block is also provided on the side facing the rectangular track. The inner wall of the second groove is provided with a third groove for sliding of the second block The third groove is provided with a fourth groove for the sliding of the first block at one end away from the second groove, the first groove is communicated with the fourth groove, several of the push rods are fixedly connected to the first block, the first block is provided with a first wedge surface at one end away from the push rod, the lower end of the second block is provided with a second wedge surface used in conjunction with the first wedge surface, the upper end of the second block is provided with a third wedge surface, one end of the third block is fixedly connected to the cutter, and the other end of the third block is provided with a fourth wedge surface used in conjunction with the third wedge surface, and an elastic member for resetting the third block is also provided in the second groove.

[0025] By adopting the above technical solution, in the initial state, the end of the push rod is arranged parallel to the outer side wall of the pressure block. When the red steel paper needs to be pressed on the protrusion, the two pressure blocks are driven to slide toward each other synchronously, so that the protrusion abuts the push rod in the direction close to the first block. Under the action of the first wedge surface and the second wedge surface, the second block moves vertically upward. Under the action of the third wedge surface and the fourth wedge surface, the third block and the cutter move synchronously in the direction close to the mold base until the cutter blade cuts the red steel paper. At the same time, the cut red steel paper is pressed on several protrusions, thereby realizing the assembly of several arc-extinguishing sheets.

[0026] Optionally, the unwinding component includes a material wheel rotatably connected to the base, a guide plate fixed above the base, a feeding block sliding on the guide plate, a delivery cylinder fixed on the guide plate, a first clamping block sliding on the guide plate, a fourth cylinder fixed on the guide plate, a second clamping block sliding on the guide plate, and a fifth cylinder fixed on the guide plate, the piston rod of the delivery cylinder is fixedly connected to the feeding block, the first clamping block and the second clamping block are respectively located on both sides of the feeding block, the piston rod of the fourth cylinder is fixedly connected to the first clamping block, and the piston rod of the fifth cylinder is fixedly connected to the second clamping block, a feeding hole is opened on the upper surface of the base, and the feeding block is located above the feeding hole.

[0029] By adopting the above technical solution, the assembled arc extinguishing unit is driven by the mold base. When the entire mold base moves to a position opposite the sixth cylinder, the piston rod of the sixth cylinder extends, causing the push plate to push the assembled arc extinguishing unit out of the mold base, thereby realizing unloading.

DETAILED DESCRIPTION

[0043] The following is combined with Figure 1-10 This application is described in further detail.

[0044] The embodiment of the present application discloses an automatic assembly device for arc-extinguishing plates.

[0045] Reference Figure 1 An automatic assembly device for arc-extinguishing plates includes a mounting table 1, on the upper surface of which a rectangular track 2 is fixedly provided, and a rectangular chute is formed on the rectangular track 2. A plurality of die holders 3 slide in the chute in the rectangular track 2, and the die holders 3 are used to insert the required number of arc-extinguishing plates. A push rod assembly 4 is provided on the upper surface of the mounting table 1, and the push rod assembly 4 can make the plurality of die holders 3 move in a direction and in a cycle in the chute. Along the moving trajectory of the die holder 3, a feeding assembly 5 for quantitatively filling the arc-extinguishing plates into the die holder 3, a press-fit assembly 6 for cutting red steel paper and squeezing it onto the arc-extinguishing plates, and a blanking assembly 7 for pushing the arc-extinguishing unit out of the die holder 3 are also provided in sequence on the surface of the mounting table 1.

[0046] Reference Figure 1 and Figure 2 In order to facilitate the directional and cyclic movement of several mold bases 3 in the slide groove of the rectangular track 2, the push rod assembly 4 is arranged in four groups, and a group of push rod assemblies 4 is provided at each of the four corners of the rectangular track 2. The push rod assembly 4 includes a first cylinder 13 and a push column 14. The first cylinder 13 is fixed to the upper surface of the mounting table 1. The push column 14 is coaxially fixed to the piston rod of the first cylinder 13, and the axial directions of two adjacent push columns 14 are arranged vertically. Each time the mold bases 3 are driven to move, the piston rods of the two diagonally arranged first cylinders 13 are extended at the same time, thereby synchronously pushing the mold bases 3 at both ends of the rectangular track 2. Then the piston rods of the remaining two diagonally arranged first cylinders 13 are extended to push the molds on both sides of the rectangular track 2. The two groups of diagonally arranged first cylinders 13 are activated at intervals, and finally the cyclic movement of several mold bases 3 in the rectangular track 2 is achieved.

[0047] Reference Figure 1 and Figure 3 In order to facilitate the automation of arc-extinguishing plate assembly, the mold base 3 is set to a porous shape. The mold base 3 includes a moving block 8, a stop block 9 and a partition 10. The moving block 8 slides in the slide groove of the rectangular track 2. The stop block 9 is integrally formed on the upper surface of the moving block 8. The partitions 10 are evenly fixed on the side wall of the stop block 9. The number of partitions 10 is preferably ten, so that a receiving cavity 11 for inserting arc-extinguishing plates is formed between two adjacent partitions 10. In order to facilitate the insertion of arc-extinguishing plates, a snap-in groove 12 is opened on the side of the stop block 9 close to the receiving cavity 11. During the assembly process, a single arc-extinguishing plate can be inserted into the snap-in groove 12. In order to facilitate the easy detachment of the assembled arc-extinguishing unit from the mold base 3, the width of the partition 10 is set to be smaller than the width of the arc-extinguishing plate itself.

[0048] Reference Figure 1 and Figure 4 In this embodiment, the feeding assembly 5 is optimally configured as two groups. The feeding assembly 5 includes a vibrating plate 15, a feeding track 16, and a collecting channel 17. The vibrating plate 15 is fixedly mounted on the upper surface of the mounting platform 1. The feeding track 16 is configured as five channels, and the vibrating plate 15 is correspondingly provided with five discharge ports. The collecting channel 17 is also configured as five channels. The vibrating plate 15 discharges five arc-extinguishing plates per single feed. The feeding track 16 is configured as a tilted one-degree angle, and the feeding port of the feeding track 16 is connected to the feeding port of the collecting channel 17. Thus, under the action of the vibrating plate 15 and the gravity of the arc-extinguishing plates themselves, each vibration can deliver one arc-extinguishing plate to each of the five collecting channels 17. In order to prevent the arc-extinguishing plates from rotating after entering the collecting channels 17, the cross-sectional shape of the inner cavity of the collecting channels 17 is made to be the same as that of the arc-extinguishing plates.

[0049] Reference Figure 3 and Figure 4The feeding assembly 5 also includes a pushing component 18 for pushing the arc-extinguishing sheets in different collecting channels 17 into the accommodating cavity 11. In this embodiment, since the feeding assembly 5 is set into two groups, the pushing components 18 are also set into two groups accordingly, and the height of one group is set greater than that of the other group.

[0050] Reference Figure 1 、 Figure 3 and Figure 4 The pusher assembly 18 comprises a second cylinder 19, a mounting block 20, and a plug-in plate 21. The second cylinder 19 is fixed to the surface of the mounting table 1, and the mounting block 20 is fixed to the end of the piston rod of the second cylinder 19. Each mounting block 20 has five plug-in plates 21, and their heights gradually increase along the length of the mounting block 20. Insertion holes 22 for receiving the plug-in plates 21 are provided on the lower sidewall of the collecting channel 17. The thickness of each insertion hole 22 is equal to the thickness of a single arc-quenching plate. Thus, each push of the mounting block 20 simultaneously pushes out five arc-quenching plates of different heights. After five movements of a single mold base 3, all five cavities 11 below the mold base 3 are completely filled. Because there are two sets of pusher assemblies 18, and the height of the second mounting block 20 is greater than that of the first, the mold base 3 can completely fill all ten cavities 11 of the mold base 3 after at least ten movements from the first mounting block 20 to the second mounting block 20.

[0051] Reference Figure 5 It is known that after the ten arc-extinguishing plates are assembled, they need to be clamped on the protrusion 60 through red steel paper to form the final assembly, so that a piece of red steel paper is clamped in each of the two groups of first clamping grooves 58, and a piece of red steel paper is clamped in one group of second clamping grooves 59. Finally, the ten arc-extinguishing plates are fixedly connected to each other through three pieces of red steel paper.

[0052] Reference Figure 1 、 Figure 5 、 Figure 6 and Figure 7 The three strips of red steel paper are respectively clamped on the three groups of protrusions 60 through the press-fit assembly 6. The press-fit assembly 6 includes a base 23, a pressure block 24, and a cutter 25. The base 23 is fixed on the table top of the mounting table 1. The base 23 is hollow. The rectangular track 2 passes through the inner cavity of the base 23. Two pressure blocks 24 are provided and are both slidably connected in the inner cavity of the base 23. The two pressure blocks 24 are respectively located on both sides of the rectangular track 2 in the initial state. There are three cutters 25, two of which are set on one of the pressure blocks 24, and the other cutter 25 is set on the other pressure block 24. The cutter 25 is slidably set on the corresponding pressure block 24.

[0053] Reference Figure 6The press-fit assembly 6 also includes a first drive component 26 for driving the two pressure blocks 24 to slide synchronously toward each other. The first drive component includes a first rack 29, a second rack 30, a gear 31, and a third cylinder 32. The first rack 29 is located above the second rack 30, and the first rack 29 and the second rack 30 are arranged opposite each other. The first rack 29 and the second rack 30 are both slidably connected within the inner cavity of the base 23. The first rack 29 is fixedly connected to one of the pressure blocks 24, and the second rack 30 is fixedly connected to the other pressure block 24. The gear 31 is rotatably connected within the inner cavity of the base 23. The gear 31 is located between the first rack 29 and the second rack 30, and both the first rack 29 and the second rack 30 are meshed with the gear 31. The third cylinder 32 is fixedly mounted on the outside of the base 23, and the piston rod end of the third cylinder 32 extends into the inner cavity of the base 23 and is fixedly connected to the first rack 29.

[0054] Reference Figure 6 and Figure 7 The press-fit assembly 6 also includes a second driving component 27 arranged on the pressing block 24 to drive the two groups of cutters 25 to slide toward each other synchronously. The second driving component 27 is set to three, two of which are set on the same pressing block 24, and the other driving component is set on another pressing block 24.

[0055] Reference Figure 1 、 Figure 5 and Figure 7 The second driving component 27 includes a push rod 33, a first block 34, a second block 35, and a third block 36. The side of the pressure block 24 facing the rectangular track 2 is provided with a plurality of first slots 37 for sliding movement of the push rod 33. The number of first slots 37 is equal to the number of protrusions 60. The side of the pressure block 24 facing the rectangular track 2 is also provided with a second slot 38 for sliding movement of the third block 36. The second slot 38 is located above the first slot 37, and the length direction of the first slot 37 is parallel to the length direction of the second slot 38. A third slot 39 for sliding movement of the second block 35 is provided on the inner side wall of the second slot 38. The third slot 39 is vertically arranged, and the second slot 38 and the third slot 39 are arranged perpendicularly. The end of the third slot 39 away from the second slot 38 is provided with a fourth slot 40 for sliding movement of the first block 34. The fourth slot 40 is connected to the first slot 37 and is arranged perpendicularly to the third slot 39.

[0056] Reference Figure 1 、 Figure 5 and Figure 7To ensure that when the pressing block 24 presses the red paper onto the protrusion 60, the protrusion 60 compresses the push rod 33, which in turn pushes the first block 34. To ensure that the push rod 33 moves while the cutter 25 slides and cuts the red paper, the cutter 25 is fixedly connected to the corresponding third block 36. A first wedge-shaped surface 41 is defined at the end of the first block 34 away from the push rod 33, and a second wedge-shaped surface 42 is defined at the lower end of the second block 35, which cooperates with the first wedge-shaped surface 41. A third wedge-shaped surface 43 is defined at the upper end of the second block 35, and a fourth wedge-shaped surface 44 is defined at the end of the third block 36 away from the cutter 25, which cooperates with the third wedge-shaped surface 43. Consequently, when the push rod 33 is pushed by the protrusion 60, the cutting edge of the cutter 25 slides toward the rectangular track 2. In order to facilitate the reset of the third block 36 after sliding, an elastic member 45 is provided in the second groove 38 . The elastic member 45 is preferably configured as a spring, one end of which is fixed to the inner wall of the second groove 38 , and the other end of the spring is fixed to the side wall of the third block 36 .

[0057] Reference Figure 8 and Figure 9 The press-fitting assembly 6 also includes an unwinding component 28 for unwinding red steel paper provided on the base 23. The unwinding component 28 includes a material wheel 46, a guide plate 47, a feeding block 48, a delivery cylinder 49, a first clamping block 50, a fourth cylinder 51, a second clamping block 52 and a fifth cylinder 53. There are three material wheels 46, which are rotatably connected to the outer wall of the base 23. The guide plate 47 is vertically arranged. The guide plate 47 is fixedly connected to the upper surface of the base 23. The feeding block 48 slides vertically on the side wall of the guide plate 47. The delivery cylinder 49 is fixed to the upper end of the guide plate 47. The piston rod of the delivery cylinder 49 is fixedly connected to the feeding block 48. The fourth cylinder 51 is fixed to one side of the feeding block 48. The first clamping block 50 is fixed on the piston rod of the fourth cylinder 51, and the first clamping block 50 forms a clamping gap with the feeding block 48. The fifth cylinder 53 is fixed to the other side of the feeding block 48 , and the second clamping block 52 is fixed to the piston rod of the fifth cylinder 53 .

[0058] Reference Figure 9 In the actual process of conveying red steel paper, the free ends of the red steel paper on two of the material wheels 46 pass through the first clamping block 50 and the feeding block 48, and the free end of the red steel paper on the other material wheel 46 passes through the second clamping block 52 and the feeding block 48, and a feeding hole 54 is opened above the base 23.
