The present invention belongs to the technical field of assembly machines, and particularly relates to a housing cotton sheet assembly machine, including a machine body. An adsorption head for adsorbing cotton sheets is provided at the lower end of the machine body and located below a transmission assembly. A first cylinder for driving the adsorption head to move is provided on the machine body. A transmission assembly for conveying the rear cover of the intercom is provided at the lower end of the machine body.

Similarly, after rotation, the adsorption head faces the rear cover, and the first cylinder also drives the adsorption head, and controls the blocking member to drive and block the cotton sheet, which can ensure that the cotton sheet is placed on the rear cover.

Description

Technical Field

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

[0002] An assembly machine is a device that combines and installs various components of an item to form the item. In the prior art, there are many types of assembly machines. This application is used for the assembly of walkie-talkies. Before assembling components such as the back cover and main board of the walkie-talkie, other components will be installed first. A cotton sheet needs to be set at the part directly attached to the main board to prevent the internal components from directly contacting the back cover of the walkie-talkie when the back cover is connected to the main board. Some precision components are protected by abutting against the cotton sheet.

[0003] In the prior art, during installation, the cut cotton sheet is fed in, and then the cotton sheet is sucked or adhered by negative pressure suction, and then rotated by a cylinder to turn the cotton sheet downward and place it in the back cover. However, the cotton sheet is generally light, so it may become loose during rotation or swinging. Even after the cotton sheet is installed in the back cover and the back cover is moved during transmission to the next step, the shaking of the device and the flow of gas during pneumatic blowing may cause the cotton sheet to move and deviate from its position on the corresponding back cover. As a result, misalignment may occur when the cotton sheet is fixed in the subsequent process, resulting in installation deviation or inconvenience for the operator to make fine adjustments. Therefore, this application proposes a new solution to ensure that the cotton sheet will not fall off or become loose by restricting and fixing the cotton sheet in advance. Summary of the Invention

[0008] Preferably, the contact surface between the pushing block and the third clamping member is an inclined surface. A spring for pushing the rotating rod to reset is provided between the rotating rod and the moving member.

[0009] Preferably, a pressing block that abuts against the back cover of the walkie-talkie is provided on the fixing member. The pressing block is slidably connected to the fixing member. A connecting rod is rotatably connected to the fixing member. A telescopic member is fixedly arranged at the end of the connecting rod away from the connection with the fixing member.

A second magnetic block that mutually adsorbs with the first strong magnetic block is provided on the bottom of the pressing block. A pulling rope is wound around the connection between the connecting rod and the fixing member. The other end of the pulling rope is connected to the first strong magnetic block in the card slot.

[0010] Preferably, a first spring for pushing the pressing block to move upward is provided in the card slot. The pressing block and the card slot are arranged in a dislocation manner and are located higher than the rotating disc.

[0011] Preferably, a rotating shaft is clamped at the connection between the connecting rod and the fixing member. The rotating shaft extends and passes out of the fixing member. A gear that is clamped with the rotating shaft is provided outside the fixing member. A rack is provided at the next process of the conveying assembly where the transmission assembly is located. The position of the rack is on the moving path of the gear and is opposite to and meshes with the gear.

[0012] Preferably, the elastic force of the first spring at the bottom of the pressing block is greater than the self-weight of the connecting rod and the telescopic member, and the elastic force of the spring is greater than the adsorption force between the first strong magnetic block and the second magnetic block. The gear meshes with the rack and the thrust of the rack is greater than the adsorption force between the first strong magnetic block and the second magnetic block, and is less than the elastic force of the spring.

[0013] Preferably, a winding member for winding the cotton sheet and an output member for conveying the cotton sheet are provided on the transmission assembly, a second cylinder for pushing the output member and the winding member to move forward is provided on the machine body, a switch pressed by the adsorption head is provided at the position where the cutting member cuts the cotton sheet on the machine body, and the switch controls the movement of the second cylinder.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0015] First, after using this device, the back cover of the walkie-talkie is placed into the fixing member, and the position of the back cover is ensured under the restriction of the positioning assembly. When the conveying assembly drives the fixing member to move to the lower end of the first cylinder, the inductor of the first cylinder senses and controls the first cylinder to open and the piston rod moves upward and moves upward along the cavity to abut against the adsorption head. At the same time, when moving upward, the connecting rope is pulled upward, so that the connecting rope drives the rotating rod of the winding to rotate, drives the rotating wheel to drive the blocking member to rotate so as to disengage from the cutting member, and cancels the blocking of the cutting member. At the same time, the adsorption head is pushed upward by the piston rod in contact, and drives the cutting member, the moving member and the blocking member to move upward synchronously to cut the cotton sheet. The cut cotton sheet is adsorbed by the adsorption head. At this time, after the first 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. Similarly, when the driving member controls the first cylinder to rotate, it can also ensure that the cotton sheet on the adsorption head will not become loose due to the fast air flow during rotation. Similarly, after rotation, the adsorption head is opposite to the back cover, and the first cylinder also drives the adsorption head and controls the blocking member to drive and block the cotton sheet to ensure that the cotton sheet is placed on the back cover;

[0016] Second, after the back cover of the walkie-talkie is placed on the fixing member and the fixing member is driven by the conveying assembly to move to the lower end of the first cylinder, the through groove on the fixing member is then embedded by the pushing block fixedly arranged on the conveying assembly, and at the same time, the clamping member three in the through groove is pushed to move. When the clamping member three moves, it moves linearly along the groove on the fixing member. At the same time, the second convex block also moves and moves along the arc groove of the rotating disc. Due to the state that the second convex block cannot move left and right but can only move forward and backward, when moving forward and backward, the rotating disc is driven to rotate along the inner wall of the arc groove. The rotating disc drives the second convex blocks on the clamping member one and the clamping member two to move, so that the clamping member one, the clamping member two and the clamping member three move synchronously to achieve the effect of clamping restriction and positioning on the back cover of the walkie-talkie placed in the fixing member. At the same time, under the pushing of the clamping member one, the clamping member two and the clamping member three, the back cover of the walkie-talkie will approach the side of the fixing member without the clamping member. Through the clamping member one, the clamping member two and the clamping member three, it can be ensured that no matter whether the back cover is placed with offset or not, the finally fixed position is always opposite to the adsorption head;

[0017] Thirdly, when the adsorption head moves downward and pushes the cotton sheet to fit the back cover of the walkie-talkie, it will press the back cover of the walkie-talkie downward, and drive the pressing block to embed into the card slot to compress the first spring. Thus, the second magnet on the pressing block of the device will directly abut against and adsorb the first powerful magnet in the card slot. Therefore, after the adsorption head moves upward and the pressure on the pressing block disappears, the first spring will push the pressing block upward again, and drive the mutually adsorbed first powerful magnet and the second magnet. After driving the first powerful magnet upward through the second magnet, it will pull the pull rope to drive the connecting rod to rotate. When the connecting rod rotates, it will drive the telescopic part to rotate synchronously and embed into the slot of the fixing part for placing the back cover, so that the orientation of the telescopic part changes, and the retractable part faces downward. At the same time, due to the downward state, the telescopic part will expand according to its own weight, and drive the abutting block to abut against the cotton sheet, thereby restricting the movement of the cotton sheet. Thus, it is ensured that when the installed cotton sheet moves and is transported to the next process, blowing in the workshop or vibration of the machine body will not cause the cotton sheet to shift, achieving the effect of restricting and fixing the cotton sheet to ensure that there is no error in fixing the cotton sheet in the subsequent process.

Detailed implementation manners

[0027] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is 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 should not be construed as a limitation of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0028] An outer shell cotton sheet assembling machine, as Figures 1-8As shown in the figure, it includes a machine body 1. A transmission component for transmitting cotton sheets is provided on the machine body 1. An adsorption head 2 for adsorbing cotton sheets is provided at the lower end of the transmission component on the machine body 1. A cylinder 1 3 for driving the adsorption head 2 to move is provided on the machine body 1. A transmission component 4 for conveying the rear cover of the walkie-talkie is provided at the lower end of the machine body 1. A driving member 5 for driving the cylinder 1 3 to rotate is provided on the machine body 1. When this device is used normally, motors and cylinders and other components are controlled through PLC or other programs. The fixing member 6 for placing the rear cover of the walkie-talkie is driven to move to the transmission component, and the fixing member 6 is accurately controlled to move to a position opposite to the cylinder. However, because the placement is not 100% accurate, it may cause the position of the cotton sheet placed on the rear cover not to be completely opposite to the adsorption head 2, so it is easy to cause the problem of the cotton sheet placed to shift. Some slots for accommodating the fixing member 6 are opened to be about the same size as the rear cover, so it may not be accurately placed manually, resulting in the need for adjustment and thus not being so fast, and the efficiency will be reduced. Secondly, the cotton sheet is adsorbed by the negative pressure suction of the adsorption head 2, which may cause the cylinder to become loose when rotating, and even cause the problem of shifting after the rear cover is placed and moved.

[0029] The conveying assembly 4 is provided with a fixing member 6 for placing the rear cover. An outer sleeve 7 fixed to the first cylinder 3 is provided outside the suction head 2. A first bump 8 embedded in the sleeve 7 is provided on the suction head 2. A chute 9 for accommodating the sliding of the first bump 8 is provided on the sleeve 7. A cavity 10 for accommodating the upward movement of the piston rod of the first cylinder 3 and abutting against the suction head 2 is provided on the suction head 2. A cutting member 11 for cutting the cotton sheet is fixedly provided on the side of the suction head 2. A moving member 12 that moves synchronously with the cutting member 11 is provided on the side of the cutting member 11. A blocking member 13 for blocking the cotton sheet and preventing the cotton sheet from loosening is rotatably connected to the moving member 12. A driving assembly for driving the blocking member 13 to rotate is provided on the sleeve 7. The driving assembly includes a rotating rod 14 rotatably connected to the moving member 12. Rotating wheels 15 connected to the blocking member 13 are provided on both sides of the rotating rod 14. A connecting rope 16 is wound around the rotating rod 14. One end of the connecting rope 16 away from the rotating rod 14 is connected to the piston rod of the first cylinder 3. A support rod 17 is fixedly provided on the sleeve 7. A pulley 18 for guiding the movement of the connecting rope 16 is rotatably connected to the support rod 1_{7}. After using this device, the fixing member 6 is driven by the conveying assembly 4 and transmitted to the lower end of the first cylinder 3. At this time, the first cylinder 3 on the machine body 1 is activated to control the piston rod to move upward, move upward along the cavity 10 at the bottom of the suction head 2 and abut against the suction head 2. Thus, when the piston rod continues to move upward and drives the suction head 2 to move upward, it will drive the bump to move upward along the chute 9, and drive the connected moving member 12 to move upward together. At the same time, before the piston rod moves upward along the cavity 10 and abuts against the suction head 2, it will first pull the connected connecting rope 16 upward, so that the connecting rope 16 moves along the pulley 18 and the pulley 18 rotates along the support rod 17, facilitating 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 spiral spring 27 for pushing the rotating rod 14 to reset is provided between the rotating rod 14 and the moving member 12. In this way, the connecting rope 16 pulls the rotating rod 14 to rotate, and synchronously drives the rotating wheel 15 to rotate to drive the blocking member 13 to rotate towards the end away from the cutting member 11, canceling the abutment and blocking with the cutting member 11. 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 after the cutting member 11 cuts the cotton sheet, it moves downward. Because the abutting friction force between the suction head 2 and the sleeve 7 is greater than the self-weight, when the piston moves downward, the suction head 2, the moving member 12, the cutting member 11 and the blocking member 13 will not fall. Therefore, the suction head 2 cannot be directly driven to move downward synchronously. It waits until it abuts against the bottom of the cavity 10 and then moves downward to continue driving the suction head 2 to move downward, and drives the moving member 12 and the blocking member 13 to move downward synchronously. When the suction head 2 is driven to move downward and the first bump 8 abuts against the bottom of the chute 9 and cannot move, it stops. Secondly, when the first cylinder 3 moves downward, the pulling of the connecting rope 16 is cancelled. After the pulling force disappears, the spiral spring 27 will push the rotating rod 14, the rotating wheel 15 and the blocking member 13 to rotate, and the blocking member 13 will re-abut against the cutting member 11 to block the cotton sheet. Thus, after the piston rod of the first cylinder 3 and the suction head 2 are reset,The driving member 5 activates the control cylinder 1 to rotate downward towards the rear cover of the intercom. Through the above settings, the limit of the cotton sheet is ensured, and it is ensured that the cotton sheet will not come loose or shift when the cylinder 1 and the suction head 2 rotate and move. Secondly, it can also ensure that the cotton sheet will not fall even if the suction of the suction head 2 fails. This setting further ensures that the cotton sheet can be accurately placed into the rear 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 sheet, the suction head 2 will automatically release the suction of the cotton sheet and can be placed downward on the rear cover. After this setting, it can be ensured that the cotton sheet is stably placed on the rear cover without deviation.

[0030] The fixing member 6 is provided with a positioning assembly for clamping and positioning the rear cover of the walkie-talkie. The positioning assembly includes a first clamping member 19, a second clamping member 20 and a third clamping member 21 that are slidably connected to the fixing member 6. A rotating disk 22 is rotatably connected inside the fixing member 6. Second bumps 23 are provided on the first clamping member 19, the second clamping member 20 and the third clamping member 21. A plurality of arc-shaped grooves 24 for accommodating the second bumps 23 to be embedded and pulling the second bumps 23 to move are provided on the rotating disk 22. A conduction groove 25 is provided at the lower end of the fixing member 6 where the third clamping member 21 is located, and the third clamping member 21 is located inside the conduction groove 25. A pushing block 26 that is embedded in the conduction groove 25 and pushes the third clamping member 21 to move is provided at the lower end of the conveying assembly 4 where the first cylinder 3 is located. The contact surface between the pushing block 26 and the third clamping member 21 is an inclined surface. Secondly, after being conveyed by the conveying assembly 4 into the lower end of the first cylinder 3 through the fixing member 6, the pushing block 26 will be embedded into the conduction groove 25, and the pushing block 26 will directly contact the third clamping member 21, and push the third clamping member 21 towards the rotating disk 22 along the inclined surface. At the same time, the second bump 23 of the third clamping member 21 will move along the arc-shaped groove 24 embedded on the rotating disk 22. And because the moving path of the third clamping member 21 is a straight line towards the rotating disk 22, and the rotating disk 22 cannot move but only rotate, thus the rotating disk 22 is rotated by pushing the second bump 23 along the arc-shaped groove 24, and the second bumps 23 on the first clamping member 19 and the second clamping member 20 are pushed to move through the arc-shaped grooves 24 opposite to the first clamping member 19 and the second clamping member 20, so that the three clamping members move synchronously, and the rear cover of the walkie-talkie inside the fixing member 6 is pushed towards the end without a clamping member, so that the rear cover moves to a position opposite to the suction head 2. Thus, the space for accommodating the rear cover on the lower fixing member 6 is larger. Therefore, it is relatively fast and convenient for manual placement of the rear cover and can be placed casually. Even if it is offset a little, through the pushing of the clamping members, it can be ensured that no matter how the rear cover is placed, finally the cover can be pushed to a position opposite to the suction head 2. The large placement space is also more convenient during placement. Compared with the two fixing members 6 in the prior art with similar sizes that are not easy to place and the fixing members 6 with a large placement space that are prone to offset, the above setting is more practical and convenient. Secondly, after being limited by the fixing member 6, the movement is stable and thus it is not easy to offset, ensuring that the suction head 2 places the cotton sheet into the specified position.

[0031] The fixing member 6 is provided with a pressing block 28 that abuts against the rear cover of the intercom. The pressing block 28 is slidably connected to the fixing member 6. A connecting rod 29 is rotatably connected to the fixing member 6. A telescopic member 30 is fixedly provided at one end of the connecting rod 29 away from the rotational connection with the fixing member 6. A contact block 31 for embedding the rear cover of the intercom and abutting against the cotton sheet is rotatably connected to the telescopic member 30. A card slot 32 for accommodating the pressing block 28 to be embedded is provided in the fixing member 6. A strong magnetic block 33 is slidably connected in the card slot 32. A magnetic block 34 that adsorbs to the strong magnetic block 33 is provided on the bottom of the pressing block 28. A pulling rope 35 is wound around the rotational connection of the connecting rod 29 and the fixing member 6. The other end of the pulling rope 35 is connected to the strong magnetic block 33 in the card slot 32. After entering the rear cover through the suction head 2 and pressing downwards, the thrust of the first cylinder 3 will cause the pressing block 28 to move downwards. A first spring 36 for pushing the pressing block 28 to move upwards is provided in the card slot 32, compressing the first spring 36 downwards. At the same time, the magnetic block 34 on the pressing block 28 moves down to the bottom and adsorbs to the strong magnetic block 33 in the card slot 32. After the cotton sheet is placed, the first cylinder 3 resets and the suction head 2 resets to cancel the extrusion of the rear cover and the pressing block 28. The first spring 36 will drive the pressing block 28 to rise. At the same time, the magnetic block 34 will drive the adsorbed strong magnetic block 33 to move upwards synchronously, and drive the connected pulling rope 35 to move upwards together. Thus, the wound connecting rod 29 is driven to rotate by the upward pulling rope 35. When the connecting rod 29 rotates, the telescopic member 30 and the contact block 31 are simultaneously driven to rotate into the fixing member 6, and the telescopic member 30 faces into the rear cover. At the same time, the telescopic member 30 slides down by its own weight to expand, so that the contact block 31 fits on the cotton sheet, restricting the movement of the cotton sheet to ensure that after installation, when the cotton sheet and the rear cover are transported to the subsequent process by the fixing member 6. It ensures that under factors such as the movement of the cotton sheet in the fixing member 6, equipment vibration, or cylinder exhaust, the cotton sheet will not move or shift, and ensures the stability of the cotton sheet. The pressing block 28 and the card slot 32 are arranged in a staggered manner with the rotating disk 22 and are higher than the rotating disk 22, so that there will be no problem of mutual conflict between the upper and lower structures.

[0032] A rotating shaft 37 is clamped at the rotational connection between the connecting rod 29 and the fixing member 6. The rotating shaft 37 extends out of the fixing member 6. A gear 38 clamped with the rotating shaft 37 is provided outside the fixing member 6. A rack 39 is provided at the next process of the conveying assembly 4 under the transmission assembly. The position of the rack 39 is on the moving path of the gear 38, opposite to and meshing with the gear 38. The elastic force of the first spring 36 at the bottom of the pressing block 28 is greater than the self-weight of the connecting rod 29 and the telescopic member 30, and the elastic force of the first spring 36 is greater than the adsorption force between the first strong magnet 33 and the second magnet 34. The gear 38 meshes with the rack 39, and the thrust of the rack 39 is greater than the adsorption force between the first strong magnet 33 and the second magnet 34, and less than the elastic force of the first spring 36. When the connecting rod 29 is driven to rotate by the pulling rope 35 and the fixing member 6 is transferred to the subsequent process, the cotton sheet will not move. After the gear 38 outside the fixing member 6 also moves synchronously to the next process, it 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 outwards from the rear cover. The telescopic member 30 is inverted and the telescopic member 30 will slide down and reset by its own weight. After such a setting, the rotation of the connecting rod 29 winds up the pulling rope 35 to drive the separation of the first strong magnet 33 and the second magnet 34. Since the pulling force of the pulling rope 35 wound up by the rotation of the gear 38 is greater than the adsorption force between the second magnet 34 and the first strong magnet 33, and the elastic force of the first spring 36 is greater than the winding force of the rotation of the gear 38, the interaction ensures the separation of the second magnet 34 and the first strong magnet 33. When the cotton sheet and the rear cover are transferred to the subsequent process, there is no deviation, and the subsequent process directly fixes the cotton sheet to complete the entire assembly. At the same time, after the assembly is completed, the telescopic member 30 and the abutting block 31 automatically reset. After the above structural setting, when placing the rear cover, it can be placed simply and casually to improve the placement efficiency and also improve the production efficiency. At the same time, the three clamping members quickly position and correct the offset rear cover to ensure that the position of the rear cover placement is the position required during processing. Finally, the cotton sheet is restricted until it enters the rear cover and is in a fixed state, ensuring that the cotton sheet is stable and always in the position where the rear cover needs to place the cotton sheet. Secondly, the air cylinder and the driving member 5 of the present application are both driven by induction components such as sensors and controllers, and achieve an automated effect through pre-set programs. This is the prior art and will not be elaborated here.

[0033] The transmission component is provided with a winding member 41 for winding the cotton sheet and an output member 40 for conveying the cotton sheet. On the body 1, there is a second cylinder 42 for pushing the output member 40 and the winding member 41 to move forward. At the position where the cutting member 11 cuts the cotton sheet on the body 1, there is a switch 43 pressed by the adsorption head 2, and the switch 43 controls the movement of the second cylinder 42. Finally, when the transmission component is driven, one end of the cotton sheet is connected to the winding member 41, and after the cotton sheet is cut, the winding member 41 will wind some of the cut cotton sheets. However, when the cotton sheet is relatively wide, it will squeeze the switch 43 during cutting. At the same time, the second cylinder 42 is activated to drive the output member 40 and the winding member 41 to move forward, driving the cotton sheet to move synchronously. The uncut end of the cotton sheet moves to the switch 43, which facilitates the next cutting by the first cylinder 3 driving the cutting member 11. After cutting again, the switch 43 will drive the air in the second cylinder 42 to be discharged, and at the same time drive the winding member 41 and the output member 40 to reset, and the winding member 41 winds, so that the subsequent cotton sheets continue to be fed to the cutting member 11, thereby continuously conveying the material and ensuring the state of complete cutting of the material.
