Description

Technical Field

[0001] This utility model relates to the technical field of transferring irregularly shaped parts cut from a strip to a strip carrier, and in particular to an irregularly shaped parts transfer device with variable distance function. Background Technology

[0002] The structure of a certain material strip is as follows Figure 1 As shown, it includes a frame 1, on which multiple carriers 2 are formed along their length. Each carrier 2 is connected to an irregularly shaped part 3. The irregularly shaped part 3 is plate-shaped and includes a part body and pins 4. The part body is fixedly connected to the carrier 2, and the pins 4 are fixed to the rear side of the part body. The structure of a certain strip-shaped carrier 5 is as follows. Figures 2-4 As shown, multiple receiving grooves 6 are formed on the top surface of the strip-shaped carrier 5 along its length direction, wherein the horizontal distance between any two adjacent receiving grooves 6 is greater than the horizontal distance between any two adjacent irregular parts 3.

[0003] The process requires that each irregularly shaped part 3 on the strip be transferred to the corresponding receiving trough 6 of the strip tray 5, so that workers can easily transfer the irregularly shaped parts 3 to the subsequent testing equipment. In addition, the process also requires that the pins 4 of each irregularly shaped part 3 be placed facing right.

[0004] The method by which the workers in the workshop transfer the various irregularly shaped parts 3 from the conveyor belt to the corresponding receiving troughs 6 of the strip carrier 5 is as follows:

[0005] S1. Workers use cutting equipment to cut all the carriers 2 with material. After cutting, the various irregularly shaped parts 3 are arranged on the table of the unloading table 7, such as... Figure 5 As shown;

[0006] S2. The worker controls the piston rod of the lifting cylinder of the transplanting equipment to extend downward. The piston rod drives the rotating cylinder and the suction head to move downward synchronously. When the bottom port of the suction head contacts the first irregular part 3, the vacuum pump connected to the top port of the suction head is started. The vacuum pump evacuates the suction head. Under negative pressure, the first irregular part 3 is adsorbed and fixed on the suction head.

[0007] S3. Control the piston rod of the lifting cylinder of the transplanting equipment to retract upward. The piston rod drives the rotary cylinder and the suction head to move upward synchronously. The suction head drives the irregular part 3 to move upward synchronously, thereby lifting the irregular part 3. After it is lifted, control the rotary cylinder to start. The rotary cylinder drives the suction head to rotate. The suction head drives the irregular part 3 to rotate synchronously. When the irregular part 3 rotates 90°, the controller controls the rotary cylinder to close, thereby changing the direction of the irregular part 3.

[0008] S4. The power mechanism of the transplanting equipment is started. The power mechanism drives the lifting cylinder, rotating cylinder, suction head and the shaped part 3 after adjustment to move synchronously towards the strip carrier plate 5. When the shaped part 3 moves directly above the first receiving sink 6 of the strip carrier plate 5, the controller controls the power mechanism of the transplanting equipment to shut down.

[0009] S5. The piston rod of the lifting cylinder extends downward, driving the rotary cylinder and suction head to move downward synchronously. The suction head drives the irregularly shaped part 3 to move downward synchronously. When the irregularly shaped part 3 moves into the receiving groove 6 of the strip carrier 5, the controller controls the vacuum pump to shut off. At this time, the irregularly shaped part 3 is placed in the receiving groove 6 of the strip carrier 5, thus completing the transfer of the first irregularly shaped part 3. Figure 6 As shown;

[0010] S6. The worker repeats steps S2-S5 multiple times to continuously transfer each irregularly shaped part 3 into its corresponding receiving slot 6 of the strip carrier 5, with the pins 4 of each irregularly shaped part 3 facing right. Figure 7 As shown.

[0011] However, although the transfer equipment used in the workshop can transfer the irregularly shaped parts 3 into the respective receiving tanks 6 of the strip carrier 5, it still exhibits the following technical defects:

[0012] The transplanting equipment can only transplant the irregularly shaped parts 3 one by one into the receiving trough 6 of the strip carrier 5. However, the large number of irregularly shaped parts 3 to be transplanted results in a long waiting time before all the cut irregularly shaped parts 3 can be transplanted into the strip carrier 5, which greatly reduces the transplanting efficiency of the irregularly shaped parts.

[0013] Therefore, there is an urgent need for a transfer device that can shorten the transfer time of irregularly shaped parts and greatly improve the transfer efficiency of irregularly shaped parts. Utility Model Content

[0044] The present invention will be further described below with reference to the accompanying drawings. The scope of protection of the present invention is not limited to the following description:

[0045] like Figures 8-12 As shown, a device for transferring irregularly shaped parts with variable distance function includes a longitudinally arranged lead screw module 8 and a lifting cylinder 10 fixed on the bottom surface of the moving part 9 of the lead screw module 8. The lead screw module 8 is mounted on a frame. The piston rod of the lifting cylinder 10 extends downward and a lifting plate 11 is fixed on the extended end. A first L-shaped plate 12 is fixed on the right end face of the lifting plate 11. A first reversing component for changing the direction of the irregularly shaped part 3 is provided between the first L-shaped plate 12 and the lifting plate 11.

[0046] The first redirection assembly includes a first motor 17 fixed on the top surface of the first L-shaped plate 12 and a first driven pulley 18 rotatably mounted on the bottom surface of the lifting plate 11 via a first rotating shaft. The output shaft of the first motor 17 passes downward through the first L-shaped plate 12, and a first driving pulley is fixed on the extended end. A first belt 19 is installed between the first driving pulley and the first driven pulley 18. A first suction head 20 is connected to the bottom of the first rotating shaft and is coaxially arranged therewith. A first suction channel 21 communicating with the inner cavity of the upper end of the first suction head 20 is opened. The first suction channel 21 is connected to the working port of the first vacuum pump via a pipe.

[0047] A downwardly extending mounting plate is fixed on the left end face of the lifting plate 11. A pitch-changing cylinder 13 is fixed on the left end face of the mounting plate. The piston rod of the pitch-changing cylinder 13 passes through the mounting plate to the right, and a movable plate 14 is fixed on the extended end. A second L-shaped plate 15 is fixed on the rear end face of the movable plate 14. A second reversing assembly for changing the direction of the irregular part 3 is provided between the second L-shaped plate 15 and the movable plate 14. The second reversing assembly is located to the left of the first reversing assembly.

[0048] The second redirection assembly includes a second motor 22 fixed on the top surface of the second L-shaped plate 15 and a second driven pulley 23 rotatably mounted on the bottom surface of the movable plate 14 via a second rotating shaft. The output shaft of the second motor 22 passes downward through the second L-shaped plate 15, and a second driving pulley is fixed on its extended end. A second belt 24 is installed between the second driving pulley and the second driven pulley 23. A second suction head 25 is connected to the bottom of the second rotating shaft and is coaxially arranged therewith. A second suction channel 26 communicating with its inner cavity is opened in the upper end of the second suction head 25. The second suction channel 26 is connected to the working port of the second vacuum pump via a pipe.

[0049] The lifting cylinder 10 is vertically arranged, and a top plate is fixed on the bottom surface of the cylinder body. A guide post 16 is fixed on the top surface of the lifting plate 11. The guide post 16 slides upward through the top plate to guide the lifting plate 11. A horizontally arranged guide rail is fixed on the bottom surface of the lifting plate 11, and the movable plate 14 is slidably mounted on the guide rail.

[0050] The distance between the first suction head 20 and the second suction head 25 is equal to the distance between two adjacent irregular parts 3, and the bottom surface of the first suction head 20 is flush with the bottom surface of the second suction head 25.

[0051] The transplanting device also includes a controller, which is electrically connected to the first motor 17, the second motor 22, the lifting cylinder 10, the variable pitch cylinder 13, the first vacuum pump, and the second vacuum pump via signal lines. The controller can control the start or stop of the first motor 17, the second motor 22, the first vacuum pump, and the second vacuum pump. At the same time, it can also control the extension or retraction of the piston rods of the lifting cylinder 10 and the variable pitch cylinder 13, which has the characteristics of high automation.

[0052] The method by which the workers in the workshop transfer the various irregularly shaped parts 3 from the conveyor belt to the corresponding receiving troughs 6 of the strip carrier 5 is as follows:

[0053] S1. Workers use cutting equipment to cut all the carriers 2 with material. After cutting, the various irregularly shaped parts 3 are arranged on the table of the unloading table 7, such as... Figure 5 As shown;

[0054] S2. The piston rod of the lifting cylinder 10 is extended downward, and the piston rod drives the lifting plate 11 to move downward. The lifting plate 11 drives the first redirecting assembly and the second redirecting assembly to move downward synchronously. The first suction head 20 of the first redirecting assembly moves towards the first irregular part 3 on the unloading platform 7. At the same time, the second suction head 25 of the second redirecting assembly moves towards the second irregular part 3 on the unloading platform 7. When the piston rod of the lifting cylinder 10 is fully extended, the bottom surfaces of the first suction head 20 and the second suction head 25 contact the top surfaces of the two irregular parts 3 respectively.

[0055] S3. Upon contact, control the first vacuum pump and the second vacuum pump. The first vacuum pump evacuates the inner cavity of the first suction head 20. Under negative pressure, the first irregular part 3 is adsorbed and fixed on the bottom surface of the first suction head 20. At the same time, the second vacuum pump evacuates the inner cavity of the second suction head 25. Under negative pressure, the second irregular part 3 is adsorbed and fixed on the second suction head 25.

[0056] S4. Control the piston rod of the lifting cylinder 10 to retract upwards. The piston rod drives the lifting plate 11 to move upwards. The lifting plate 11 drives the first redirection assembly and the second redirection assembly to move upwards synchronously. The first suction head 20 of the first redirection assembly drives the first irregular part 3 to move upwards. At the same time, the second suction head 25 of the second redirection assembly drives the second irregular part 3 to move upwards, so that the two irregular parts 3 are away from the unloading table 7.

[0057] S5. The specific operation steps for reversing the direction of the two irregularly shaped parts 3 are as follows:

[0058] S51, the piston rod of the control pitch cylinder 13 retracts to the left, the piston rod drives the movable plate 14 to move to the left, the movable plate 14 drives the second L-shaped plate 15 to move to the left in sync, and then drives the second redirection assembly to move to the left. The second redirection assembly drives the second suction head 25 and the second irregular part 3 to move to the left in sync, thereby increasing the horizontal distance between the second irregular part 3 and the first irregular part 3. When the piston rod of the control pitch cylinder 13 is fully retracted, the pitch of the two irregular parts 3 is completed. At this time, the horizontal distance between the two irregular parts 3 is exactly equal to the distance between the two adjacent receiving troughs 6 in the strip tray 5.

[0059] S52, the second motor 22 of the second redirection component is started, the second motor 22 drives the second driving pulley to rotate, the second driving pulley drives the second driven pulley 23 to rotate via the second belt 24, the second driven pulley 23 drives the second rotating shaft to rotate, the second rotating shaft drives the second suction head 25 to rotate, the second suction head 25 drives the second irregular part 3 to rotate synchronously, when the pin 4 on the second irregular part 3 rotates 90°, the controller controls the second motor 22 to turn off;

[0060] Simultaneously, the first motor 17 controlling the first reversing component starts, the first motor 17 drives the first driving pulley to rotate, the first driving pulley drives the first driven pulley 18 to rotate via the first belt 19, the first driven pulley 18 drives the first rotating shaft to rotate, the first rotating shaft drives the first suction head 20 to rotate, the first suction head 20 drives the first irregular part 3 to rotate synchronously, when the pin 4 on the first irregular part 3 rotates 90°, the controller controls the first motor 17 to shut down, thus finally completing the reversal of the two irregular parts 3;

[0061] S6. Control the moving part 9 of the lead screw module 8 to move backward. The moving part drives the lifting cylinder 10, the first redirecting component, the second redirecting component, the first suction head 20, the second suction head 25 and the two irregular parts 3 to move backward synchronously. When the two irregular parts 3 move to the top of the two receiving sinks 6 located at the first end of the strip tray 5, the controller controls the lead screw module 8 to close.

[0062] S7. The piston rod of the lifting cylinder 10 extends downward, driving the lifting plate 11 to move downward. The lifting plate 11 drives the first and second redirecting components to move downward synchronously, thereby driving the two redirected irregularly shaped parts 3 to move downward. When the two irregularly shaped parts 3 enter the two receiving slots 6 of the strip carrier 5 respectively, the controller lifts the cylinder 10 and simultaneously controls the first and second vacuum pumps to shut down. At this time, the pins 4 of the two irregularly shaped parts 3 are placed in the strip carrier 5 with their pins facing the same direction, thus completing the transfer of the two irregularly shaped parts 3. Figure 13 As shown;

[0063] S8. After the transfer of the two irregular parts 3 is completed, the piston rod of the lifting cylinder 10 is retracted upward, the piston rod drives the lifting plate 11 to move upward, and the lifting plate 11 drives the first reversing assembly and the second reversing assembly to reset; then the worker moves the strip tray 5 to the left a distance so that the other two receiving troughs 6 on the strip tray 5 can enter the receiving station.

[0064] S9. The worker repeats steps S2-S8 multiple times to continuously transfer each irregularly shaped part 3 into its corresponding receiving slot 6 of the strip carrier 5, with the pins 4 of each irregularly shaped part 3 facing right. Figure 7 As shown.

[0065] As can be seen from steps S2 to S9, this transplanting device, through the coordinated operation of the lifting cylinder 10, the pitch-changing cylinder 13, the first redirecting component, and the second redirecting component, can place two irregularly shaped parts 3 into the strip-shaped carrier 5 simultaneously. Therefore, compared to existing transplanting equipment that can only transplant irregularly shaped parts 3 one by one into the receiving trough 6 of the strip-shaped carrier 5, this transplanting device can transplant twice the number of parts at a time, thus achieving the goal of transplanting all the cut irregularly shaped parts 3 into the strip-shaped carrier 5 in a short time, thereby greatly improving the transplanting efficiency of irregularly shaped parts.
