Description

Technical Field

[0001] The utility model relates to the field of chip processing equipment, in particular to a curved rail direct connection mechanism and a corresponding chip receiving machine. Background Art

[0002] After the initial production of the chip is completed, it is placed on the incoming tape. The chip production equipment outputs the chip in the form of a tape, and then the tape with the chip enters the chip receiver and is stored in the tray. In order to ensure the stability of the equipment, the tray in the chip receiver is usually lower at the receiving position, lower than the tape output position of the chip tape output device. In order to achieve the docking between the chip receiver and the chip production equipment, an inclined rail is set on the chip receiver to directly connect to the tape output position of the chip production equipment. Since the tape of the chip production equipment is output in the horizontal direction, it is easy to get stuck if it enters the inclined rail directly, which affects the stability of the receiving material.

[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0031] In the figures, structurally similar elements are denoted by the same reference numerals.

[0032] Please refer to Figure 1 The utility model is a chip receiving machine, comprising a chassis 300, a receiving mechanism 200 and a curved track direct connection mechanism 100. The chassis 300 is a square box structure. Figure 1 Only part of the structure of the chassis 300 is shown. The receiving mechanism 200 is arranged in the chassis 300, and is used to wind the tape 900 with the chip onto the material tray; the curved track direct connection mechanism 100 is arranged in the chassis 300, one end of which extends to the receiving mechanism 200, and the other end is used for the chip tape output device, so as to transfer the tape of the chip tape output device to the receiving mechanism 200.

[0033] like Figure 1 , Figure 2 As shown, the curved rail direct connection mechanism 100 includes an inclined rail 1, a flat rail 2 and a transmission assembly 3; the inclined rail 1 and the flat rail 2 are connected in a curved shape, and the transmission assembly 3 is arranged on the flat rail 2 to drive the material belt in the flat rail 2 to be transmitted to the inclined rail 1.

[0034] Combination Figure 2 , Figure 3As shown, the inclined rail 1 is inclined, and is provided with an inclined channel 10 for the supply tape to pass through, and its bottom end extends to the receiving mechanism 200. One end of the flat rail 2 is adjustable and rotatably connected to the top of the inclined rail 1, and the other end is used to connect with the chip tape output device. By rotating the flat rail 2, the height position of the other end can be adjusted, so as to facilitate docking with tape output ports of different heights, which is convenient for use.

[0035] like Figure 4 As described above, the flat rail 2 is provided with a flat channel 20 through which the feed belt passes. The end of the flat channel 20 facing the inclined channel 10 is curved and connected to the inclined channel 10. The curved structure of the flat channel 20 can make the process of the feed belt entering the inclined channel 10 from the flat channel 20 smoother.

[0036] The transmission assembly 3 is arranged at one end of the flat rail 2 adjacent to the inclined rail 1, and includes a driving wheel 31, a pressure wheel 32, a pressure rod 33 and a transmission motor 34. The transmission motor 34 is fixed below the flat rail 2 and is connected to the driving wheel 31 by transmission. The driving wheel 31 is located below the flat rail 2, and its top surface extends into the flat channel 20. The pressure rod 33 is arranged obliquely, and its bottom end is rotatably connected to the flat rail 2. The pressure wheel 32 is rotatably connected to the top of the pressure rod 33 and is located above the flat channel 20. The pressure wheel 32 and the driving wheel 31 are arranged opposite to each other in the vertical direction to clamp the material belt and drive the material belt to move. Since the pressure rod 33 is arranged obliquely, the pressure wheel 32 can press the material belt downward by its own gravity, so that the material belt is pressed between the pressure wheel 32 and the driving wheel 31. When the transmission motor 34 drives the driving wheel 31 to rotate, the material belt can move toward the inclined channel 10, so that the transmission assembly 3 is used to make the material belt transmission more stable and reliable, thereby improving the material collection stability.

[0037] like Figure 3 As shown, the inclined rail 1 includes two inclined plates 13, a first inclined rod 11 and a second inclined rod 12. The two inclined plates 13 are parallel and oppositely arranged. The first inclined rod 11 is located above the second inclined rod 12. The two are arranged at intervals and fixed between the two inclined plates 13, and an inclined channel 10 is formed between the four. The inclined rail 1 has a simple structure, is easy to assemble, and is convenient for forming the inclined channel 10. It is also convenient to disassemble and maintain it, and is conducive to the docking between the inclined rail 1 and the flat rail 2.

[0038] A connecting portion 131 is formed at one end of each inclined plate 13 adjacent to the flat rail 2, and the connecting portion 131 protrudes from the first inclined rod 11 and the second inclined rod 12 toward the flat rail 2. An upper curved section 201 and a lower curved section 202 are provided at one end of the flat rail 2 adjacent to the inclined rail 1, and an arc-shaped curved structure of the flat channel 20 is formed between the upper curved section 201 and the lower curved section 202. Both the upper curved section 201 and the lower curved section 202 are located between the two connecting portions 131.

[0039] One end of the lower curved section 202 adjacent to the inclined rail 1 is rotatably connected to the two connecting parts 131 through a rotating shaft, and an adjusting rod 203 is provided at the bottom of the lower curved section 202. An adjusting hole 130 is provided on each connecting part 131, and the adjusting hole 130 is arc-shaped, and its center is the axis of the rotating shaft. The two ends of the adjusting rod 203 are respectively penetrated through the two adjusting holes 130, and the adjusting rod 203 is threadedly connected with an adjusting nut 204, which is located on the outside of the connecting part 131 and is used to lock the lower curved section 202 between the two connecting parts 131, thereby locking the adjusting rod 203 in the position of the adjusting hole 130 to adjust the position of the flat rail 2.

[0040] When the position of the flat rail 2 needs to be adjusted, the adjustment nut 204 is loosened, and the adjustment rod 203 can move in the adjustment hole 130, so that the lower curved section 202 rotates, thereby rotating the flat rail 2, and then adjusting the angular position of the flat rail 2, so that the flat rail 2 is conveniently aligned with the material belt output port. After alignment, the adjustment nut 204 can be tightened, and the two lower curved sections 202 can be clamped between the two connecting parts 131 by using the two connecting parts 131 to fix the position of the flat rail 2. Since the upper curved section 201 is also located between the two connecting parts 131, the upper curved section 201 can also be clamped at the same time, so that the position of the flat rail 2 is fixed firmly and reliably. The adjustment nut 204 can be a butterfly nut or a plum nut for easy rotation.

[0041] One end of the adjusting rod 203 may be connected to an adjusting nut 204 and the other end may be provided with a cap, or both ends may be provided with adjusting nuts 204. The threads of the adjusting nut 204 and the adjusting rod 203 may be used to cooperate to achieve the two connecting parts 131 to clamp the lower curved section 202.

[0042] In this embodiment, the inclined rail 1 is located inside the chassis 300, and the flat rail 2 is located outside the chassis 300, so as to facilitate adjustment of the angle position of the flat rail 2. A detachable fixed connection mechanism can be provided between the flat rail 2 and the chassis 300, and the flat rail 2 can be fixedly connected to the chassis 300 after the position of the flat rail 2 is adjusted, thereby improving stability.

[0043] An extension portion 111 is provided at one end of the first oblique rod 11 facing the flat rail 2, and the upper curved section 201 is provided with two docking portions 2011, which are arranged at intervals. In the axial direction of the rotating shaft, the extension portion 111 is located between the two docking portions 2011, and the extension portion 111 and the docking portion 2011 are arranged at intervals so that the extension portion 111 can move between the two. By using the cooperation between the extension portion 111 and the two docking portions 2011, the first oblique rod 11 and the upper curved section 201 can be mutually embedded in the length direction of the material strip, so that the material strip can smoothly transition between the flat channel 20 and the oblique channel 10, and the material strip is stuck between the first oblique rod 11 and the upper curved section 201.

[0044] A first guide surface 1101 is provided at the bottom of the extension portion 111, and a second guide surface 1201 is provided at one end of the second inclined rod 12 facing the flat rail 2. Both the first guide surface 1101 and the second guide surface 1201 are inclined surfaces, and the distance between the two gradually increases in the direction toward the flat rail 2, so that the material belt can enter the inclined channel 10 from the flat channel 20 more smoothly.

[0045] A lifting cylinder 29 is provided on the flat rail 2, and the piston rod of the lifting cylinder 29 abuts against the bottom of the top end of the pressure rod 33 to drive the pressure rod 33 to drive the pressure wheel 32 to rotate upward, thereby making the pressure wheel 32 move upward away from the driving wheel 31, so as to move the end of the material strip between the pressure wheel 32 and the driving wheel 31 in the initial state.

[0046] A tension spring 28 is provided between the top of the pressure rod 33 and the lifting cylinder 29, and the tension spring 28 is used to provide elastic force so that the pressure rod 33 drives the pressure wheel 32 to rotate downward, so that the material belt is further compressed between the pressure wheel 32 and the driving wheel 31, so as to drive the material belt to be transmitted.

[0047] In this embodiment, the flat rail 2 includes a first side plate 21, a second side plate 22, an upper flat rod 23 and a lower flat rod 24. The first side plate 21 is parallel to and opposite to the second side plate 22. The upper flat rod 23 is located above the lower flat rod 24. The two are spaced apart and connected between the first side plate 21 and the second side plate 22, and a flat channel 20 is formed between the four.

[0048] The upper flat bar 23 includes a supporting flat bar 231 and a docking bar 232, which are arranged and spaced apart along the conveying direction of the material belt and are both fixedly connected to the first side plate 21. The pressing wheel 32 is located between the supporting flat bar and the docking bar 232 to extend from there between the two into the flat channel 20. The upper curved section 201 can be integrally formed with the docking bar 232, or the two components can be fixedly connected.

[0049] like Figure 4 , Figure 5 As shown, the curved rail direct connection mechanism 100 further includes a buffer assembly 4, which is arranged on the flat rail 2 and includes a buffer cylinder 41 and a lifting plate 42. The lower flat rod 24 includes a first rod 241, two buffer rods 243 and a second rod 242 arranged in sequence along the conveying direction of the material belt. The first rod 241 and the second rod 242 are both fixed between the first side plate 21 and the second side plate 22.

[0050] The opposite ends of the two buffer rods 243 are rotatably connected to the first rod 241 and the second rod 242 respectively.

[0051] A guide post 244 is provided on one side of each buffer rod 243 facing the second side plate 22. The lifting plate 42 is located on the side of the second side plate 22 away from the first side plate 21. Two guide holes 420 are provided on the lifting plate 42. The guide holes 420 are strip-shaped and arranged along the conveying direction of the material belt. The two guide posts 244 are movably arranged in the two guide holes 420.

[0052] The cache cylinder 41 is fixed to the supporting horizontal rod 231 and connected to the lifting plate 42 to drive the lifting plate 42 to move up and down, and the two cache rods 243 are rotated through the cooperation of the guide column 244 and the guide hole 420, and then the gap between the two cache rods 243 is adjusted so that the material belt can enter the gap between the two cache rods 243, thereby caching the material belt.

[0053] A bearing may be provided on the guide column 244 , and the bearing contacts the hole wall of the guide hole 420 to ensure the stability of the relative movement between the guide column 244 and the guide hole 420 and reduce wear.

[0054] The buffer cylinder 41 is located at the middle position between the two guide posts 244, and a buffer tension spring 43 is connected between the guide post 244 and the piston rod of the buffer cylinder 41. When the two buffer rods 243 rotate downward, the distance between the two guide posts 244 gradually increases, and the distance between the guide post 244 and the buffer cylinder 41 gradually increases. The elastic force of the buffer tension spring 43 can make the two guide posts 244 move toward the buffer cylinder 41, that is, the two buffer rods 243 rotate upward, which is conducive to the upward rotation of the two buffer rods 243.

[0055] A cache box 44 is further provided below the two cache rods 243. The top of the cache box 44 is open, and one side wall thereof extends upward and is fixed to the first side plate 21. The material strip entering between the two cache rods 243 can be accommodated in the cache box 44 to prevent the material strip from being damaged by foreign objects.

[0056] When the output speed of the material list is greater than the material receiving speed of the material receiving mechanism 200, the buffer cylinder 41 is actuated to cause the two buffer rods 243 to rotate downward, and the excess material strip can enter the buffer box 44 from the gap between the two buffer rods 243 for buffering.

[0057] Sensors may be provided at the input port of the flat track 2 and the output port of the inclined track 1 to detect the input and output speeds of the material belt in the curved track direct connection mechanism 100 , thereby facilitating determination of whether to cache the material belt.

[0058] In summary, although the present invention has been disclosed as above in terms of preferred embodiments, the above preferred embodiments are not intended to limit the present invention. A person skilled in the art may make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be based on the scope defined in the claims.
