Description

Technical Field

[0001] The invention discloses an assembling machine, in particular to an outer shell cotton sheet assembling machine. Background Art

[0002] An assembly machine is a device that combines and installs the various components of an object to form the object. There are many types of assembly machines in the prior art, and the present application is used for the assembly of walkie-talkies. Before assembling the back cover of the walkie-talkie with the main board and other objects, other components will be installed first. Cotton sheets need to be set at the parts that directly fit with the main board to prevent internal objects from directly contacting the back cover of the walkie-talkie when the back cover is connected to the main board. Some precision objects are protected by the cotton sheets.

[0003] In the prior art, the cut cotton sheets are sent in during installation, and then the cotton sheets are sucked or adhered by negative pressure suction, and then the cylinder is rotated to turn the cotton sheets downward and put them into the back cover. However, the cotton sheets are generally light, so they may become loose when rotated or swung. Even after being installed on the back cover and in the process of moving the back cover when it is transferred to the next step, the shaking of the equipment and the flow of gas during pneumatic blowing may cause the cotton sheets to move out of the corresponding position on the back cover, which will cause misalignment when the cotton sheets are transferred to the subsequent process and fixed, resulting in deviations in the installation or the need for fine-tuning by the operator, causing inconvenience. Therefore, the present application proposes a new solution to ensure that the cotton sheets will not fall or become loose by limiting and fixing them in advance. Summary of the invention

[0011] Preferably, the elastic force of spring 1 at the bottom of the pressing block is greater than the deadweight of the connecting rod and the telescopic part, and the elastic force of spring 1 is greater than the adsorption force of strong magnetic block 1 and magnetic block 2, the gear is meshed with the rack and the rack thrust is greater than the adsorption force of strong magnetic block 1 and magnetic block 2, and less than the elastic force of spring 1.

[0012] Preferably, the transmission component is provided with a winding piece for winding up the cotton sheet and an output piece for conveying the cotton sheet, the machine body is provided with a second cylinder for pushing the output piece and the winding piece forward, the machine body is provided with a switch pressed by the suction head at the cutting piece for cutting the cotton sheet, and the switch controls the movement of the second cylinder.

[0013] Compared with the prior art, the present invention has the following beneficial effects: First, after using this device, the back cover of the intercom is placed into the fixing part, and the position of the back cover is ensured by the restriction of the positioning component. When the conveying component drives the fixing part to move to the lower end of the cylinder, the sensor of cylinder one senses and controls cylinder one to open the piston rod to move upward and move up along the cavity to abut against the adsorption head. At the same time, the connecting rope is pulled upward during the upward movement, so that the connecting rope drives the winding rotating rod to rotate, and the driving wheel drives the blocking part to rotate so as to disengage from the cutting part and cancel the blocking of the cutting part. At the same time, the adsorption head is pushed upward by the abutted piston rod and drives the cutting part, the moving part and the blocking part synchronously. The cotton sheet is cut by moving upward, and the cut cotton sheet is adsorbed by the adsorption head. At this time, after the cylinder drives the piston rod to move downward, the pulling of the connecting rope is cancelled and the spring will push the blocking member, the rotating wheel and the rotating rod to reset. At this time, the blocking member can block the cotton sheet to prevent the cotton sheet from falling off the adsorption head. At the same time, when the driving member controls the cylinder to rotate, it can also ensure that the cotton sheet of the adsorption head will not be loosened due to the fast air flow during rotation. At the same time, the adsorption head after rotation is opposite to the back cover, and the cylinder drives the adsorption head in the same way, and controls the blocking member to drive the cotton sheet to ensure that the cotton sheet is placed on the back cover. Secondly, after the back cover of the intercom is placed on the fixing part, and the fixing part is driven by the conveying assembly to move to the lower end of the cylinder, at this time, the conducting groove on the fixing part is embedded by the pushing block fixedly arranged on the conveying assembly, and the clamping part three in the conducting groove is pushed to move. When the clamping part three moves, it moves straight along the groove on the fixing part, and the protrusion two also moves accordingly, and moves along the arc groove of the rotating disk. When the protrusion two cannot move left and right but can only move forward and backward, the rotating disk is driven to rotate along the inner wall of the arc groove during the forward and backward movement, and the protrusion two on the clamping part one and the clamping part two are driven to move by the rotating disk, so that the clamping part one, the clamping part two and the clamping part three move synchronously to achieve the clamping restriction and positioning effect on the back cover of the intercom placed in the fixing part. At the same time, under the push of the clamping part one, the clamping part two and the clamping part three, the back cover of the intercom will be close to the side of the fixing part without the clamping part. The clamping part one, the clamping part two and the clamping part three can ensure that the back cover is always opposite to the adsorption head regardless of whether it is offset or not. Thirdly, when the adsorption head moves down and pushes the cotton sheet to fit the back cover of the intercom, the back cover of the intercom will be pressed down, and the pressing block will be driven to be embedded in the card slot to compress the spring 1. As a result, the magnetic block 2 on the pressing block under the device will directly contact and adsorb the strong magnetic block 1 in the card slot. As a result, after the adsorption head moves up, the pressure of the pressing block disappears, and the spring 1 will push the pressing block upward again, and drive the strong magnetic block 1 and the magnetic block 2 that are adsorbed to each other. After the strong magnetic block 1 is driven upward by the magnetic block 2, the pull rope will be pulled to drive the connecting rod to rotate. When the connecting rod rotates, it drives the telescopic part to rotate synchronously and embed into the groove of the rear cover of the fixed part, so that the direction of the telescopic part changes, and the telescopic part is downward. At the same time, due to the downward state, the telescopic part will expand according to its own weight, and drive the abutment block to abut on the cotton piece, so as to limit the movement of the cotton piece. In this way, it is ensured that when the installed cotton piece is moved and transported to the next process, the blowing in the workshop or the vibration of the machine body will not cause the cotton piece to shift, so as to limit and fix the cotton piece to ensure that there will be no error in fixing the cotton piece in the next process.

DETAILED DESCRIPTION

[0016] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, which are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0017] A shell cotton sheet assembly machine, such as Figure 1-Figure 8As shown, the machine body 1 comprises a transmission component for transmitting cotton pieces, a suction head 2 for absorbing cotton pieces is provided at the lower end of the transmission component of the machine body 1, a cylinder 3 for driving the suction head 2 to move is provided on the machine body 1, a transmission component 4 for conveying the back cover of the intercom is provided at the lower end of the machine body 1, and a driving member 5 for driving the cylinder 3 to rotate is provided on the machine body 1. The normal use of this device is to control the motor and the cylinder and other objects through the PLC or other program settings to drive the fixing member 6 on which the back cover of the intercom is placed to move to the transmission component, and the fixing member 6 is moved to the position opposite to the cylinder by accurately controlling the fixing member 6. The position of the cotton sheet can be adjusted, but because the placement is not 100% accurate, the position of the cotton sheet placed on the back cover may not be completely opposite to the suction head 2, which may easily cause the cotton sheet placed in it to be offset. Some of the grooves for accommodating the fixing part 6 are almost the same size as the back cover. In this case, the manual placement may not be accurate, resulting in the need for adjustment, so it is not so fast, which will result in reduced efficiency. Secondly, the cotton sheet is sucked by the suction head 2 under negative pressure to absorb the cotton sheet, which may cause it to loosen when the cylinder rotates, or even move after being placed in the back cover, causing the cotton sheet to deviate.

[0018] The conveying assembly 4 is provided with a fixing part 6 for placing the back cover, the suction head 2 is provided with a set 7 fixed to the cylinder 3, the suction head 2 is provided with a protrusion 8 embedded in the set 7, the set 7 is provided with a slide groove 9 for accommodating the sliding of the protrusion 8, the suction head 2 is provided with a cavity 10 for accommodating the upward movement of the piston rod of the cylinder 3 and abutting against the suction head 2, a cutting piece 11 for cutting cotton sheets is fixedly provided on the side of the suction head 2, a moving piece 12 that moves synchronously with the cutting piece 11 is provided on the side of the cutting piece 11, a blocking piece 13 for blocking the cotton sheets and preventing the cotton sheets from loosening is rotatably connected to the moving piece 12, and a driving assembly for driving the blocking piece 13 to rotate is provided on the set 7, and the driving assembly includes a rotating rod 14 rotatably connected to the moving piece 12, and the rotating rod 14 is provided with a rotating rod 14 on both sides. A rotating wheel 15 connected to the blocking member 13, a connecting rope 16 is wound on the rotating rod 14, and the end of the connecting rope 16 away from the rotating rod 14 is connected to the piston rod of the cylinder 3. A support rod 17 is fixedly arranged on the kit 7, and a pulley 18 for guiding the movement of the connecting rope 16 is rotatably connected to the support rod 17. After using this device, the fixing member 6 is driven and transmitted to the lower end of the cylinder 3 by the conveying component 4. At this time, the cylinder 3 on the body 1 is turned on to control the piston rod to move upward, move up along the cavity 10 at the bottom of the adsorption head 2 and abut against the adsorption head 2. As a result, the piston rod continues to move upward to drive the adsorption head 2 to move upward, which will drive the protrusion to move up along the slide groove 9, and drive the connected moving member 12 to move up together. At the same time, the piston rod moves up along the cavity 10 and abuts against the adsorption head 2 before The connected connecting rope 16 will be pulled upward first, so that the connecting rope 16 moves along the pulley 18 and the pulley 18 rotates along the support rod 17, which facilitates the movement of the connecting rope 16 to pull the connecting rope 16 at the rotating rod 14 downward, and the pulley 18 changes the moving direction of the connecting rope 16. A spring 27 is provided between the rotating rod 14 and the moving part 12 to push the rotating rod 14 to reset. The connecting rope 16 pulls the rotating rod 14 to rotate, and synchronously drives the rotating wheel 15 to rotate, thereby driving the blocking member 13 to rotate toward the end away from the cutting member 11, canceling the abutment and blocking with the cutting member 11, and at the same time, the suction head 2 is pushed to drive the moving member 12, the cutting member 11 and the blocking member 13 to move upward synchronously, and the cutting member 11 moves downward after cutting the cotton sheet. The mutual abutment friction between the sets 7 is greater than the deadweight. Therefore, when the piston moves downward, the suction head 2, the moving part 12, the cutting piece 11 and the blocking part 13 will not fall, and thus the suction head 2 cannot be directly driven to move downward synchronously. It has to wait for the abutment with the bottom of the cavity 10 before moving downward to continue to drive the suction head 2 downward, and drive the moving part 12 and the blocking part 13 to move downward synchronously, and wait until the suction head 2 is driven to move downward and the protrusion 8 abuts against the bottom of the slide groove 9 and cannot move, then it stops. Secondly, when the cylinder 3 moves downward, the pulling on the connecting rope 16 is cancelled. After the pulling force disappears, the clockwork 27 will push the rotating rod 14, the rotating wheel 15 and the blocking part 13 to rotate, and the blocking part 13 will abut against the cutting piece 11 again to block the cotton piece. Therefore, after the piston rod of the cylinder 3 and the suction head 2 are reset,The driving member 5 opens the control cylinder 13 and rotates downward toward the back cover of the intercom. The above setting ensures the limit of the cotton piece, ensuring that the cotton piece will not be loosened or offset when the cylinder 13 and the suction head 2 rotate and move. Secondly, it can also ensure that the cotton piece will not fall if the suction head 2 fails. This setting further ensures that the cotton piece can be accurately placed in the back cover. Secondly, when moving downward, the piston still drives the suction head 2 and the blocking member 13 in the same operation. After the blocking member 13 cancels the restriction on the cotton piece, the suction head 2 will automatically release the suction cotton piece and can be placed downward on the back cover. This setting can ensure that the cotton piece is stably placed on the back cover without any deviation.

[0019] The fixing member 6 is provided with a positioning assembly for clamping and positioning the back cover of the intercom. The positioning assembly includes a clamping member 19, a clamping member 20 and a clamping member 3 21 which are slidably connected to the fixing member 6, a rotating disk 22 is rotatably connected inside the fixing member 6, and a protrusion 23 is provided on the clamping member 19, the clamping member 20 and the clamping member 3 21, and a plurality of arc grooves 24 are provided on the rotating disk 22 for accommodating the protrusion 23 to be embedded and pulling the protrusion 23 to move, a conducting groove 25 is provided at the lower end of the clamping member 3 21 of the fixing member 6, and the clamping member 3 21 is located in the conducting groove 25, and a pushing block 26 is provided at the lower end of the cylinder 1 3 for embedding the conducting groove 25 and pushing the clamping member 3 21 to move. The push block 26 and the clamping member 3 21 abutting surface are inclined surfaces. Secondly, after being transported by the conveying assembly 4 into the lower end of the cylinder 1 3 through the fixing member 6, the push block 26 will be embedded in the conducting groove 25, and the push block 26 will directly abut against the clamping member 3 21, and push the clamping member 3 21 toward the rotating disk 22 along the inclined surface. At the same time, the protrusion 23 of the clamping member 3 21 will move along the arc groove 24 embedded on the rotating disk 22, and because the moving path of the clamping member 3 21 is a straight line toward the rotating disk 22, and the rotating disk 22 cannot move but can only rotate, the protrusion 23 is pushed along the arc groove 24 to make the rotating disk 22 rotate, and the protrusion 23 on the clamping member 19 and the clamping member 20 is pushed and moved through the arc groove 24 opposite to the clamping member 19 and the clamping member 20, so that the three The clamping parts move synchronously and push the back cover of the intercom in the fixing part 6 to the end without the clamping parts, so that the back cover moves to the position opposite to the adsorption head 2. Therefore, the space for accommodating the back cover on the fixing part 6 is larger, so it is faster and more convenient to place the back cover manually and it can be placed anywhere. Even if it is offset a little, the push of the clamping parts can ensure that the back cover can be pushed to the position opposite to the adsorption head 2 no matter how it is placed. The large placement space can also be more convenient when placing. Compared with the two types of fixing parts 6 in the prior art, which are similar in size and difficult to place and have a larger placement space and are easy to deviate, the above arrangement is more practical and convenient. Secondly, the stable movement after the fixing part 6 is limited is not easy to deviate, so as to ensure that the adsorption head 2 places the cotton sheet in the specified position.

[0020] A pressing block 28 abutting against the back cover of the intercom is provided on the fixing member 6, and the pressing block 28 is slidably connected to the fixing member 6. A connecting rod 29 is rotatably connected to the fixing member 6, and a telescopic member 30 is fixedly provided on the end of the connecting rod 29 away from the rotatable connection with the fixing member 6. An abutting block 31 for embedding into the back cover of the intercom and abutting against the cotton piece is rotatably connected to the telescopic member 30. A card slot 32 for accommodating the embedding of the pressing block 28 is provided in the fixing member 6, and a strong magnetic block 33 is slidably connected in the card slot 32. A magnetic block 2 34 that is attracted to the strong magnetic block 33 is provided at the bottom of the pressing block 28. A pull rope 35 is wrapped around the rotatable connection between the connecting rod 29 and the fixing member 6, and the other end of the pull rope 35 is connected to the strong magnetic block 33 in the card slot 32. After the suction head 2 enters the back cover and presses downward, the thrust of the cylinder 3 will cause the pressing block 28 to move downward. A spring 36 is provided in the card slot 32 for pushing the pressing block 28 upward. The spring 36 is compressed downward, and at the same time, the magnetic block 34 on the pressing block 28 moves down to the bottom and is adsorbed by the strong magnetic block 33 in the card slot 32. After the cotton sheet is placed, the cylinder 3 is reset and the suction head 2 is reset to cancel the squeezing of the back cover and the pressing block 28. The spring 36 will drive the pressing block 28 to rise, and the magnetic block 34 will The strong magnetic block 33 that is adsorbed is driven to move upward synchronously, and the connected pull rope 35 is driven to move upward together, thereby the winding connecting rod 29 is driven to rotate through the upward pull rope 35, and when the connecting rod 29 rotates, the telescopic part 30 and the abutment block 31 are driven to rotate into the fixing part 6 at the same time, and the telescopic part 30 faces the back cover, and at the same time, the telescopic part 30 is unfolded by sliding down under its own weight so that the abutment block 31 fits on the cotton piece, limiting the movement of the cotton piece to ensure that after the installation is completed, the cotton piece and the back cover are transferred to the subsequent process by the fixing part 6. It is ensured that the cotton piece will not move and deviate due to factors such as the movement of the fixing part 6, the shaking of the equipment or the exhaust of the cylinder, and the stability of the cotton piece is ensured. The pressing block 28 and the card slot 32 are offset from the rotating disk 22 and are located higher than the rotating disk 22, so there will be no problem of conflict between the upper and lower structures.

[0021] A rotating shaft 37 is clamped at the rotation connection between the connecting rod 29 and the fixing member 6. The rotating shaft 37 extends and passes through the fixing member 6. A gear 38 is provided on the fixing member 6 to be clamped with the rotating shaft 37. The conveying assembly 4 is provided with a rack 39 at the next process of the transmission assembly. The rack 39 is located on the moving path of the gear 38 and is opposite to and meshed with the gear 38. The elastic force of the spring 1 36 at the bottom of the pressing block 28 is greater than the deadweight of the connecting rod 29 and the telescopic member 30, and the elastic force of the spring 1 36 is greater than the force of the strong magnetic block 1 33 and the magnetic block 2 34 to be adsorbed. The gear 38 is meshed with the rack 39 and the thrust of the rack 39 is greater than the force of the strong magnetic block 1 33 and the magnetic block 2 34 to be adsorbed, and is less than the elastic force of the spring 1 36. After the connecting rod 29 is driven by the pull rope 35 to rotate and the fixing member 6 is transmitted to the subsequent process, the cotton sheet will not move, and the gear 38 outside the fixing member 6 will also move synchronously to the next process and will directly abut against the rack 39 on the conveying assembly 4. After continuing to move, the gear 38 is pushed by the rack 39 to mesh and rotate along the rack 39, thereby driving the rotating shaft 37 to drive the connecting rod 29 to rotate. At the same time, the rotation of the connecting rod 29 drives the telescopic member 30 to rotate outward from the rear cover, and the telescopic member 30 turns over and the telescopic member 30 will slide down and reset by its own weight. Therefore, the rear connecting rod 29 is set to rotate the winding pull rope 35 to drive the strong magnetic block 1 33 to loosen the magnetic block 2 34. Because the pulling force of the winding pull rope 35 rotating by the gear 38 is greater than the adsorption force between the magnetic block 2 34 and the strong magnetic block 1 33, and the elastic force of the spring 1 36 is greater than the winding force of the gear 38, the mutual action force ensures that the magnetic block 2 34 is separated from the strong magnetic block 1 33. When the cotton piece and the back cover are transmitted to the subsequent process, there is no offset and the subsequent process directly fixes the cotton piece to complete the entire assembly. At the same time, the telescopic part 30 and the abutment block 31 are automatically reset after assembly. When the back cover is placed after the above-mentioned structure is set, it can be placed simply and arbitrarily to improve the placement efficiency and also improve the production efficiency. At the same time, the three clamping parts are used to quickly position and correct the offset back cover to ensure that the position of the back cover is the position required during processing. Finally, the cotton piece can be restricted after being cut and is in a fixed state until it enters the back cover, ensuring that the cotton piece is always stable in the position where the back cover needs to be placed. Secondly, the cylinder and the drive member 5 of the present application are driven by sensing components such as sensors and controllers, and the automation effect is achieved through advance program settings. This is a prior art and will not be discussed in detail here.

[0022] The transmission component is provided with a winding member 41 for winding up the cotton sheet and an output member 40 for conveying the cotton sheet. The machine body 1 is provided with a cylinder 42 for pushing the output member 40 and the winding member 41 forward. The machine body 1 is provided with a switch 43 pressed by the suction head 2 at the place where the cutting member 11 cuts the cotton sheet, and the switch 43 controls the movement of the cylinder 42. When the transmission component is driven, one end of the cotton sheet is connected to the winding member 41, and the winding member 41 will wind up some of the cut cotton sheets after the cotton sheets are cut. However, when the cotton sheets are cut wider, they will squeeze the switch 43, and at the same time, the cylinder 2 42 is turned on to drive the output member 40 and the winding member 41 to move forward, driving the cotton sheet to move synchronously, and the uncut end of the cotton sheet moves to the switch 43, which is convenient for the next cutting by the cylinder 1 3 to drive the cutting member 11. After cutting again, the switch 43 will be driven to discharge the air of the cylinder 2 42, and at the same time drive the winding member 41 and the output member 40 to reset, and the winding member 41 will be wound, so that the following cotton sheets continue to be fed into the cutting member 11, thereby setting a state of continuous material transportation and ensuring that the material is completely cut.

[0023] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention.
