Description

Technical Field

[0001] This application relates to the technical field of polyethylene disc correction equipment, and in particular to a polyethylene disc shape correction equipment. Background Art

[0002] Automated SMT mounting production of semiconductor parts is a method of directly soldering semiconductor parts onto a printed circuit board. Semiconductor components include chips and small connectors. Usually, the chips and small connectors are encapsulated in a long strip of soft tape, and the long strip of soft tape is further wrapped around and packaged in two polyethylene discs with a diameter of 320 mm. One side of the polyethylene disc protrudes for storing the long strip of soft tape, and the other side has a concave structure. The regular shape of the polyethylene disc facilitates the automated SMT mounting production of semiconductor parts.

[0003] Currently, after the ejector pin of the injection molding machine ejects the polyethylene disc, the operator takes out the polyethylene disc and at the same time takes away the waste generated during the production process of the polyethylene disc, discards the waste, holds both sides of the diameter of the polyethylene disc with both hands, bends the edge of the polyethylene disc to correct the shape of the polyethylene disc, then changes the position of holding the polyethylene disc with both hands, bends the edge of the polyethylene disc again, and repeats the above process several times until the edge of the polyethylene disc is flat and easy to stack.

[0004] The above process of correcting the shape of the polyethylene disc requires the operator to manually correct it repeatedly, with cumbersome steps and low work efficiency, and there is room for improvement. Summary of the Utility Model

[0005] In order to simplify the steps of correcting the shape of the polyethylene disc and improve work efficiency, this application provides a polyethylene disc shape correction equipment.

[0006] A polyethylene disc shape correction equipment provided by this application adopts the following technical solutions:

[0007] A polyethylene disc shape correction equipment includes a frame, a support frame arranged on the frame, a pressing disc slidably connected to the support frame, and a plurality of suction cup assemblies arranged on the support frame for adsorbing the polyethylene disc. The plurality of suction cup assemblies are evenly distributed at the edge of the polyethylene disc. A driving member is arranged on the support frame, and the driving member drives the pressing disc to slide towards the middle of the polyethylene disc.

[0008] By adopting the above technical solution, when the produced polyethylene disc needs to be corrected, the suction cup assembly adsorbs the outer wall of the edge of the polyethylene disc, fixes the polyethylene disc on a plurality of suction cup assemblies, starts the driving member, and the driving member drives the pressure plate to abut against the middle of the polyethylene disc. The pressure plate and the suction cup assembly provide forces in opposite directions to the polyethylene disc, realizing the correction of the shape of the polyethylene disc, without the need to adjust the position of the polyethylene disc, and correcting the shape of the polyethylene disc multiple times, simplifying the correction steps, thereby improving the work efficiency.

[0009] Optionally, three suction cup assemblies are provided.

[0010] By adopting the above technical solution, before correction, the edge of the polyethylene disc is adsorbed and fixed by three suction cup assemblies, and the polyethylene disc is better fixed by a limited number of suction cup assemblies.

[0011] Optionally, the suction cup assembly includes an adjusting rod arranged on the support frame, a nozzle fixed to the end of the adjusting rod, and a suction cup fixed to the end of the nozzle, and the nozzle supplies air to the suction cup.

[0012] By adopting the above technical solution, when the suction cup abuts against the polyethylene disc, the external air supply assembly sucks air from the suction cup through the nozzle, a negative pressure is formed inside the suction cup, and the polyethylene disc is fixed on the adjusting rod under the action of air pressure; when the suction cup assembly to be used is separated from the polyethylene disc, the external air supply assembly inflates the suction cup through the nozzle, the atmospheric pressure is restored inside the suction cup, and the polyethylene disc falls off from the suction cup assembly.

[0013] Optionally, a robotic arm for driving the support frame to move is arranged on the frame. The base of the robotic arm is installed on the frame, the free end of the robotic arm is fixed to the side wall of the support frame, a connecting sleeve is arranged on the side wall of the support frame, the end of the adjusting rod away from the nozzle is slidably connected to the inner wall of the connecting sleeve, and an elastic member for resetting the adjusting rod is arranged on the connecting sleeve. One end of the elastic member is fixed to the outer wall of the nozzle, and the other end is fixed to the outer wall of the connecting sleeve.

[0014] By adopting the above technical solution, before correction, the outer wall of the polyethylene disc is uneven. At this time, the robotic arm drives the support frame to move towards the side wall of the polyethylene disc. The suction cup close to the convex part of the polyethylene disc contacts the polyethylene disc in advance. The support frame continues to move towards the outer wall of the polyethylene disc. The end of the adjusting rod on the suction cup that has contacted the outer wall of the polyethylene disc in advance slides towards the inner wall of the connecting sleeve, and the elastic member is compressed. The arrangement of the slidably connected adjusting rod and the elastic member enables the suction cup that has contacted the side wall of the polyethylene disc in advance to move along with the convexity on the side wall of the polyethylene disc until several suction cups all contact the polyethylene disc. Under the adsorption of several suction cups, the polyethylene disc is adsorbed and fixed on the suction cups, so that several suction cups are all fixed to the side wall of the polyethylene disc, improving the stability of fixing the polyethylene disc.

[0015] Optionally, the connecting sleeve is slidably connected to the support frame, and a locking member for restricting the sliding of the connecting sleeve is arranged on the outer wall of the connecting sleeve.

[0016] By adopting the above technical solution, the staff manually adjusts the position of the connecting sleeve on the support frame according to the diameter of the polyethylene disc to be corrected, so that several suction cups can be evenly adsorbed on the edge of the polyethylene disc. After completing the adjustment of the position of the connecting sleeve, the locking member restricts the sliding of the connecting sleeve, making the connection between the connecting sleeve and the support frame more stable, thereby reducing the interference caused during the correction process of the polyethylene disc.

[0017] Optionally, the support frame includes a bearing rod and an adjusting frame slidably connected to the bearing rod. The connecting sleeve is slidably connected to the adjusting frame. The bearing rod is fixedly connected to the free end of the robotic arm, and a fixing member for limiting the sliding of the adjusting frame is arranged on the outer wall of the bearing rod.

[0018] By adopting the above technical solution, when it is necessary to correct polyethylene discs with a large difference in radius, a large amount of adjustment of the distance between the suction cups is required. At this time, first drive the position of the adjusting frame on the bearing frame, and then adjust the position of the connecting sleeve on the adjusting frame. The arrangement of the slidably connected adjusting frame makes it more convenient to adjust the distance between the suction cups, thereby facilitating the correction of polyethylene discs with a larger diameter range. After completing the adjustment of the position of the adjusting frame, lock the adjusting frame through the fixing member to reduce the possibility of the adjusting frame sliding during the correction process.

[0019] Optionally, the locking member includes a locking block slidably connected to the adjusting frame and a limiting pin threadedly connected to the locking block. The locking block is fixed to the outer wall of the connecting sleeve, and the limiting pin can abut against the side wall of the adjusting frame.

[0020] By adopting the above technical solution, when the adjusting frame and the connecting sleeve need to slide, the limit pin is screwed out, and when the adjusting frame and the connecting sleeve need to be fixed, the limit pin is screwed in, and the limit pin abuts against the outer walls of the support frame and the connecting sleeve.

[0021] Optionally, a waste clamping structure is provided on the frame, and the waste clamping structure is located near the suction cup.

[0022] By adopting the above technical solution, during the production process of the polyethylene disc, polyethylene waste will be generated at the same time. During the correction process of the polyethylene disc, the clamping structure can clamp and clean the waste.

[0023] Optionally, the waste clamping structure includes a sliding rod slidably disposed on the frame, connecting rods slidably connected to both ends of the sliding rod, and clamping blocks fixed to the ends of the connecting rods. The two connecting rods are hinged, and clamping blocks are fixed on both connecting rods. A power member for driving the sliding rod to slide is provided on the frame.

[0024] By adopting the above technical solution, when clamping the waste, the power member provides a traction force to the push rod, and the push rod slides away from the polyethylene disc. The push rod is away from the hinge point of the connecting rod, and the connecting rod drives the clamping block at the end to clamp the waste. When discarding the waste, the power member provides a thrust to the push rod, and the push rod slides towards the polyethylene disc. The push rod slides towards the hinge point of the connecting rod, and the connecting rod drives the clamping block at the end to open and discard the waste.

[0025] In summary, the present application includes at least one of the following beneficial technical effects:

[0026] 1. When correcting the shape of the polyethylene disc, the suction cup assembly provides an adsorption force for the polyethylene disc, and the pressure plate abuts against the middle part of the polyethylene disc under the action of the driving member. Several suction cup assemblies provide an adsorption force, and the pressure plate applies a pressure to the middle part of the polyethylene disc. This process lasts for 20 seconds to eliminate the internal stress of the polyethylene disc, thereby changing the shape of the polyethylene disc. This process simplifies the shape correction process of the polyethylene disc and improves work efficiency.

[0027] 2. When it is necessary to adjust the correction amount, the position of the suction cup assembly can be adjusted through the support rod and the adjusting frame, and the position where the suction cup adsorbs the polyethylene disc is changed to meet the correction amount requirements in different situations.

[0028] 3. The waste clamping structure removes the waste during the production process of the polyethylene disc, and the correction process and the waste clamping and cleaning are carried out simultaneously, thereby improving work efficiency. Description of the Drawings

Detailed implementation manners

[0034] The following further Figures 1-4 describes the present application in detail with reference to the

[0035] The embodiment of the present application discloses a polyethylene disc shape correction device.

[0036] Referring to Figure 1 , a polyethylene disc shape correction device includes a frame 1, a robotic arm 6 disposed on the frame 1, and a support frame 2 fixed to the robotic arm 6. The base of the robotic arm 6 is mounted on the frame 1, and the support frame 2 is fixed to the end of the robotic arm 6 away from the frame 1 by bolts. The support frame 2 includes a bearing rod 21 and an adjusting frame 22 slidably connected to the outer wall of the bearing rod 21. The outer walls of the bearing rod 21 and the adjusting frame 22 are both provided with chutes. In the embodiment of the present application, two adjusting frames 22 are preferably provided.

[0037] Referring to Figure 2 , a pressure plate 3 is slidably connected to the bearing rod 21, and a driving member 5 for driving the pressure plate 3 is provided. In the embodiment of the application, the driving machine 5 is preferably an air pump. The driving member 5 is fixed to the middle of the bearing rod 21, and the pressure plate 3 is coaxially fixed to the piston rod of the driving member 5 through a connecting rod. The driving member 5 drives the pressure plate 3 to slide towards the polyethylene disc. A plurality of suction cup assemblies 4 for providing an adsorption force to the polyethylene disc are provided on the adjusting frame 22. Three suction cup assemblies 4 are preferably provided. Under the action of the driving member 5, the pressure plate 3 provides a thrust to the polyethylene disc, and the suction cup assemblies 4 provide an adsorption force to the edge portion of the polyethylene disc. Under the combined action of the thrust and the adsorption force, the shape of the polyethylene disc is corrected.

[0038] Referring to Figure 2, the suction cup assembly 4 includes an adjusting rod 41, a nozzle 42 welded and fixed to one end of the adjusting rod 41 close to the polyethylene disc, and a suction cup 43 welded to the end of the nozzle 42. A connecting sleeve 7 is slidably connected to the end of the adjusting rod 41 away from the nozzle 42, and the connecting sleeve 7 is slidably connected to the side wall of the adjusting frame 22, and an elastic member 8 is provided on the connecting sleeve 7.

[0039] In the embodiment of the present application, the elastic member 8 is preferably a spring. One end of the elastic member 8 is welded to the outer wall of the connecting sleeve 7, and the other end is welded to the end of the nozzle 42 away from the suction cup 43. During the process of shape correction, due to the irregular outer wall of the polyethylene disc, some of the suction cups 43 come into contact with the outer wall of the polyethylene disc in advance. Under the movement of the robotic arm 6, the elastic member 8 is compressed, and the three suction cups 43 all abut against the outer wall of the polyethylene disc. Through the action of the three elastic members 8, the three suction cups 43 are all adsorbed on the outer wall of the polyethylene disc, making the correction process more stable. The setting of the elastic member 8 facilitates the sliding of the adjusting rod 41, reduces the acting force between the suction cup 43 and the polyethylene disc, and at the same time facilitates the adsorption and fixation of several suction cups 43 on the side wall of the polyethylene disc.

[0040] Multiple nozzles 42 are connected by a trachea. When the suction cup 43 adsorbs the polyethylene disc, the nozzle 42 sucks out the air between the suction cup 43 and the polyethylene disc. Under the action of the external air pressure, the polyethylene disc is adsorbed on the suction cup 43. When the adsorption force of the suction cup 43 is released, the nozzle 42 ventilates the suction cup 43, and the air pressure between the suction cup 43 and the polyethylene disc returns to the atmospheric pressure, causing the polyethylene disc to fall off.

[0041] Reference Figure 3 , a locking member 9 for restricting the sliding of the connecting sleeve 7 is provided on the outer wall of the connecting sleeve 7, and a fixing member 10 for restricting the sliding of the adjusting frame 22 is provided on the outer wall of the bearing rod 21. Under the combined action of the locking member 9 and the fixing member 10, the shape correction process of the polyethylene disc can be carried out stably. The locking member 9 includes a locking block 91 welded to the outer wall of the connecting sleeve 7 and a limit pin 92 threadedly connected to the locking block 91. When adjusting the relative position of the connecting sleeve 7, the limit pin 92 is loosened. When restricting the sliding of the connecting sleeve 7, the limit pin 92 is tightened, and the limit pin 92 abuts against the inner wall of the chute of the adjusting frame 22, thereby restricting the sliding of the limit pin 92.

[0042] Reference Figure 2 and Figure 3 , the fixing member 10 includes a fixing block 101 threadedly fixed to the outer walls of the bearing rod 21 and the adjusting frame 22 and a fixing pin 102 threadedly connected to the fixing block 101. The fixing pin 102 slides in the chutes of the bearing rod 21 and the adjusting frame 22. The fixing block 101 is of an L-shaped structure, and preferably three fixing pins 102 are provided. Two fixing pins 102 abut against the inner wall of the chute of the bearing rod 21, and one fixing pin 102 abuts against the outer wall of the chute of the adjusting frame 22 to restrict the sliding of the adjusting member 22.

[0043] When adjusting the relative position of the adjusting frame 22 on the bearing rod 21, loosen the fixing pin 102. The fixing pin 102 can slide in the chute. After the position adjustment is completed, tighten the fixing pin 102. The fixing pin 102 abuts against the inner wall of the bearing rod 21 and the chute of the adjusting frame 22, and the fixing block 101 abuts against the outer walls of the bearing rod 21 and the adjusting frame 22, restricting the sliding between the bearing rod 21 and the adjusting rod 41.

[0044] Reference Figure 2 and Figure 4 Figure 2 , a waste clamping structure 11 for discarding waste is further provided on the frame 1. The waste clamping structure 11 includes a slide bar 111 slidably disposed on the frame 1, connecting rods 112 slidably connected to both ends of the slide bar 111, and clamping blocks 113 welded to the ends of the connecting rods 112. Through grooves are formed on the side walls of the connecting rods 112, and the slide bar 111 slides in the two through grooves. The two connecting rods 112 are hinged by a rotating shaft. The clamping blocks 113 are located at the ends of the connecting rods 112 on the side away from the frame 1. A power member 12 for driving the slide bar 111 to slide is provided on the frame 1. The power member 12 is preferably an electromagnetic telescopic rod, which is welded and fixed on the frame 1, and the slide bar 111 is fixedly connected to the push rod of the power member 12 through a connecting rod.

[0045] When clamping the waste, the power member 12 drives the slide bar 111 to slide in a direction away from the hinge point of the connecting rod 112. Under the traction of the slide bar 111, the connecting rod 112 drives the ends of the connecting rod 112 to fit together, and the clamping blocks 113 close inward to clamp the waste. When discarding the waste, the power member 12 drives the slide bar 111 to slide in a direction close to the hinge point of the connecting rod 112, and the connecting rod 112 drives the two clamping blocks 113 to move away from each other. After the waste loses the clamping force, it drops. In the embodiment of the present application, the connecting rod 112 is located at a position close to the suction cup 43, and the process of the waste clamping structure 11 clamping the waste is synchronized with the process of the suction cup 43 adsorbing the polyethylene disc, thereby improving the working efficiency.

[0046] The implementation principle of a polyethylene disc shape correction device in the embodiment of the present application is as follows: The frame 1 is usually fixed to the side wall of the injection molding machine by bolts, facilitating the correction of the produced polyethylene disc. The robotic arm 6 is arranged side by side with the waste clamping structure 11. When the robotic arm 6 drives the support frame 2 to slide towards the polyethylene disc, the waste clamping structure 11 clamps the waste. The ventilation assembly evacuates the air in the suction cup 43 through the air nozzle 42, and the suction cup 43 adsorbs the polyethylene disc. The pressing plate 3 pushes the polyethylene disc under the action of the driving member 5, maintaining the position of the pressing plate 3 and the suction cup 43 for 20 s. Subsequently, the driving member 5 drives the pressing plate 3 away from the polyethylene disc, and the thrust applied to the middle of the polyethylene disc disappears. The pneumatic structure ventilates the suction cup 43 through the air nozzle 42, and the suction cup 43 loses the adsorption force, and the polyethylene disc falls off the device. The overall shape correction steps of the polyethylene disc are simple, thereby improving the working efficiency.

[0047] The above are all the preferred embodiments of this application, and do not limit the protection scope of this application accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application shall be covered within the protection scope of this application.
