Description

Technical Field

[0001] The invention relates to the field of clamp forming, and in particular to a clamp detection and packaging machine. Background Art

[0002] The elastic clamp is a common fastener for pipe joints. After the elastic clamp is formed, its shape and size need to be tested to ensure that it can be packaged and sold only after it is qualified. The commonly used testing equipment at present is shown in the turntable mechanism of the testing equipment disclosed in the application number CN201711440140.0, including a rotating motor, a rotating bracket and a glass turntable. The rotating motor is arranged vertically, and the glass turntable is installed on the rotating bracket and driven by the rotating motor. The periphery of the glass turntable is provided with several camera detection stations for taking pictures and several material boxes for sorting and classifying workpieces. Each material box is provided with a blowing mechanism, and the blowing mechanism includes a blowing needle and a solenoid valve. The solenoid valve controls the opening or closing of the blowing needle. The blowing needle is aimed at the workpieces to be inspected on the glass turntable. During the inspection, the workpiece is photographed by a camera, and then compared with the qualified products in the database, and the qualified products or products with different defects are classified, and the workpiece is blown into the corresponding material box by a blowing needle.

[0003] In order to facilitate storage and sales, qualified clamps need to be packaged, and in order to reduce packaging costs, packaging bags can be used for packaging. Because the size of the clamps is small, multiple clamps can be placed in each packaging bag, and in order to facilitate counting, the number of clamps in each packaging bag must be the same. Although the above equipment can detect the clamps, manual counting is still required to ensure that the number of clamps in each packaging bag is the same, and manual counting is labor-intensive and prone to errors. Summary of the invention

[0004] The present invention is intended to provide a clamp detection and packaging machine, which can count qualified clamps when detecting the clamps, so as to ensure that the number of clamps in each packaging bag is the same.

[0005] To achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a clamp detection packaging machine includes a detection unit, the detection unit includes a camera, a turntable and a detection power part, the detection power part is used to drive the turntable to rotate, the camera is opposite to the turntable, the camera is connected to a controller, and the controller is provided with a counting module; a material guiding unit, a sealing unit and a clamping unit are also provided, the material guiding unit includes a hopper, a material guiding assembly and a closing assembly, the material guiding assembly includes a material guiding cylinder and a vertical pushing member, the material guiding cylinder is arranged at the lower part of the hopper and slidably cooperates with the hopper, the lower end of the material guiding cylinder is lower than the upper end, the vertical pushing member is connected to the material guiding cylinder and is used to drive the material guiding cylinder to slide; the closing assembly includes a closing plate and a closing member, the closing plate is used to close the material guiding cylinder, the closing member is connected to the closing plate and is used to drive the closing plate to open and close the material guiding cylinder; the controller is connected to the closing member and is used to control the opening and closing of the closing member;

[0006] The sealing unit is lower than the material guide barrel, and the sealing unit includes two sealing components. The vertical projections of the two sealing components are respectively located on both sides of the material guide barrel. The two sealing components each include a suction cup, a heating element and a sealing element. The suction cups of the two sealing components are opposite to each other, and the heating elements of the two sealing components are opposite to each other. The two sealing components are respectively used to drive the two suction cups to slide horizontally.

[0007] The clamping unit is lower than the hopper and includes two clamping assemblies. The line between the two clamping assemblies is perpendicular to the line between the two closing assemblies. Each clamping assembly includes a transverse driving member and a clamp. The transverse power member is used to drive the clamp to slide transversely.

[0008] The beneficial effects of this program are:

[0009] 1. The camera in this solution takes a picture of the clamp, and the controller determines whether it is a qualified product based on the image. If it is determined to be a qualified product, the air blowing needle blows the clamp off the turntable and drops it into the hopper for storage. At the same time, the counting module is controlled to add 1. When the number counted by the counting module reaches the preset value, it proves that the number of qualified products falling into the hopper reaches the required number of a packaging bag, so manual counting is no longer required, reducing the probability of counting errors and reducing manual workload.

[0010] 2. The closing plate in this solution can close the guide tube. When the closing plate is not opened, the clamp to be packaged is stored above the closing plate. When the lower end of the guide tube is inserted into the packaging bag, the closing plate is opened again. At this time, the clamp falls from the closing plate into the packaging bag. Therefore, during the entire packaging process, the clamp first falls from the conveyor belt onto the closing plate, and then falls from the closing plate into the packaging bag, rather than falling directly from the conveyor belt into the packaging bag. The height of the clamp is smaller each time it falls, which prevents the clamp from falling too high and causing the speed of falling into the packaging bag to be too high, resulting in damage to the packaging bag. At the same time, the collision force between the clamps in this solution is also smaller, which effectively prevents the buckle on the clamp from falling off due to collision.

[0011] 3. In the process of sealing the previous packaging bag, moving the next packaging bag to the bottom of the material guide barrel and opening the opening, the sealing plate remains in a closed state, and the clamps on the conveyor belt can continue to be stored in the material guide barrel. When the opening of the next packaging bag is opened and the number of clamps in the material guide barrel basically reaches the requirement, the material guide barrel is slid downward again, and the required number of clamps are all put into the packaging bag at one time, that is, the clamps can fall from the conveyor belt at the same time as the sealing of the previous packaging bag and the installation of the next packaging bag, without having to wait until all the clamps in the previous packaging bag fall out, and then seal the previous packaging bag and install the next packaging bag before the next clamp can fall out from the conveyor belt. There is no need to keep the packaging bag open for a long time, and all the clamps can be dropped out in a short time, effectively improving the clamp packaging efficiency.

[0012] Furthermore, a support unit is provided below the hopper, the support unit includes a support assembly, the support assembly includes a support plate and a material discharge member, the support plate is located below the material guide barrel, and the material discharge member is used to drive the support plate to rotate.

[0013] The beneficial effect of this solution is that the support plate in this solution can support the packaging bag, so that after the clamp falls into the packaging bag, the packaging bag is damaged due to excessive weight.

[0014] Furthermore, the support unit also includes a vertical adjustment component, which includes an adjustment frame, a base frame and a screw rod. The adjustment frame is arranged on the base frame and can slide vertically. The screw rod is arranged on the base frame and is used to push the adjustment frame vertically.

[0015] The beneficial effect of this solution is that the height of the material discharging member and the support plate can be adjusted by moving the adjustment frame vertically, so as to be suitable for packaging bags and material guide barrels of different heights.

[0016] Furthermore, the support assembly also includes a connecting rod, one end of which is connected to the support plate, the middle part is hinged to the adjustment frame, and the other end is slidably connected to a rotating shaft, which is connected to the discharge member.

[0017] The beneficial effect of this solution is that the material discharge member drives the connecting rod to rotate, thereby driving the support plate to tilt and reset, and the structure is simple.

[0018] Furthermore, the support plate is V-shaped, and the length of the support plate at a side away from the connecting rod is greater than the length of the support plate at a side close to the connecting rod.

[0019] The beneficial effect of this solution is that when the clamp falls into the packaging bag, since there is no connection between adjacent clamps, the clamp on the upper side is easy to roll outward and collide with the side wall of the packaging bag under the action of gravity. During the collision, the pressure between the clamp and the side wall of the packaging bag is relatively large, and there is still a risk of scratching the packaging bag. The support plate in this solution can limit the clamp in the packaging bag, preventing the clamp on the upper side from rolling down, and also preventing the packaging bag from tilting, resulting in excessive force between the packaging bag and the suction cup, causing damage to the mouth of the packaging bag or falling off the suction cup.

[0020] When the packaging bag is heat-sealed, the support plate tilts, and the packaging bag on the support plate slides downward along the side wall of the support plate away from the connecting rod. The side wall is relatively long and can guide the packaging bag as it slides, thereby ensuring that the packaging bag can slide into the collection frame below or onto the conveyor belt connected to the next process.

[0021] Furthermore, the thread on the screw rod is matched with a nut seat, and at least two clamping blocks are detachably connected to the adjustment frame. All the clamping blocks are distributed along the circumference of the nut seat, and the side walls of the clamping blocks facing the nut seat are V-shaped and abut against the side walls of the nut seat.

[0022] The beneficial effect of this solution is that the clamping block can limit the nut seat so that the nut seat will not rotate with the screw when the screw rotates. Compared with directly detachably connecting the nut seat to the adjustment frame, this solution limits the nut seat by the clamping block, so that there is no need to install fasteners such as bolts on the nut seat, thereby avoiding damage to the strength of the nut seat by the fasteners.

[0023] Furthermore, a shell is rotatably connected to the screw rod, and a limiting groove with an opening facing downward is provided on the shell. The shell is covered on all the blocks in a state of opening facing downward and is detachably connected to the adjustment frame.

[0024] The beneficial effect of this solution is that the housing can limit the nut seat axially to prevent the nut seat from falling out of the clamping block.

[0025] Furthermore, an air blowing needle is provided on the turntable, and the air blowing needle is connected to the controller.

[0026] The beneficial effect of this solution is that the controller can automatically control the start of the air blowing needle, quickly blow the qualified clamp off the turntable, and the operation is simple.

[0027] Furthermore, a conveyor belt is provided between the turntable and the hopper, and a plurality of conveyor belts are provided, and a plurality of air blowing needles are also provided, and the plurality of air blowing needles correspond one to one with the conveyor belts.

[0028] The beneficial effect of this solution is that the clamp can be better conveyed to the hopper through the conveyor belt.

[0029] Furthermore, one side wall of the hopper is an inclined surface, the inclined surface is located below the conveyor belt, and the length of the inclined surface is greater than other adjacent side walls of the hopper.

[0030] The beneficial effect of this solution is that the clamp first falls from the conveyor belt onto the inclined surface, and then slowly rolls from the inclined surface into the bottom of the hopper due to the smaller slope of the inclined surface, so the collision between the clamp and the bottom of the hopper is smaller, thus avoiding deformation of the clamp during the packaging process or falling off of the buckle on the clamp.

[0038] Example

[0039] The embodiment is basically as follows Figures 1 to 4 As shown, the clamp detection packaging machine includes a frame, a detection unit, a material guiding unit, a sealing unit, a supporting unit and a clamping unit. The detection unit includes a camera, a turntable 7 and a detection power part. The frame is rotatably connected to a rotating bracket 71 through a bearing. The detection power part adopts a motor, and the detection power part is connected to the rotating bracket 71 through a coupling to drive the rotating bracket 71 to rotate. The turntable 7 is annular and is horizontally mounted on the rotating bracket 71 by bolts.

[0040] The camera is arranged above the turntable 7 and facing the turntable 7, and is used to take pictures of the clamp placed on the turntable 7. The camera is connected to a controller. Specifically, the controller with a counting module is used in this embodiment. The controller compares the received image with the qualified product, and marks the clamp that matches the shape and size of the qualified product as a qualified product, and marks the clamp that does not meet the requirements as a defective product. Each time a qualified product is detected, the statistical value of the counting module is increased by one. Specifically, the above detection method is the same as the prior art, and will not be repeated in this embodiment. The controller is connected to three blowing needles. The camera and the three blowing needles are distributed in sequence along the circumference of the turntable 7, and the blowing needles are located on the inner side of the turntable 7 and horizontally face the outer side of the turntable 7. The first two blowing needles are used to blow the qualified products off the turntable 7, so that the clamp first passes through the camera and then the first two blowing needles, and finally passes through the third blowing needle. Two conveyor belts 8 are arranged on the side of the turntable 7. One end of the two conveyor belts 8 is respectively opposite to the two blowing needles, and the other end extends to the side away from the turntable 7, which is used to convey the qualified clamp to the material guide unit.

[0041] The material guide unit includes a hopper 1, a material guide assembly and a closing assembly. The hopper 1 is mounted on the frame by bolts. The right side wall of the silo above the hopper 1 is an inclined surface 15. In this embodiment, the upper end of the inclined surface 15 is aligned with the conveyor belt 8, so that when the clamp falls from the conveyor belt 8, it first falls on the inclined surface 15, is buffered by the inclined surface 15, and then slides downward along the inclined surface 15 into the lower part of the hopper 1, further reducing the speed of the clamp when it falls to the lower part of the hopper 1.

[0042] The material guide assembly includes a material guide barrel 12 and a vertical pusher 11. The material guide barrel 12 is vertically sleeved at the lower part of the hopper 1. The vertical pusher 11 includes two linear actuators. The two linear actuators are installed on the front and rear sides of the hopper 1 by bolts. The push rod of the vertical pusher 11 faces downward and is connected to the top of the material guide barrel 12 by bolts to drive the material guide barrel 12 to move vertically. The closing assembly is arranged at the lower end of the material guide barrel 12. The closing assembly includes a closing plate and a closing member. The closing plate is higher than the material guide barrel 12 and is arranged laterally to the side of the hopper 1. The closing plate passes through the left side wall of the hopper 1 laterally and is in clearance with the hopper 1. The closing member also adopts a linear actuator. The push rod of the closing member is connected to the closing plate and is used to slide the closing plate to the right into the hopper 1 to close the material guide barrel 12. The closing piece in this embodiment is electrically connected to the controller. When the value of the counting module reaches a preset value, the controller can start the closing piece and control the push rod of the closing piece to retract and open the hopper 1; and after a certain interval, the push rod of the closing piece is controlled to extend so that the closing plate recloses the hopper 1. Specifically, the interval time is determined based on the bottom opening of the hopper 1 and the number of clamps that need to be placed in each packaging bag to ensure that within the interval time, all the clamps in the hopper 1 can fall into the packaging bag, and before the closing plate completely closes the hopper 1, the next clamp on the turntable 7 has not moved to the blowing needle.

[0043] The sealing unit is lower than the guide barrel 12. The sealing unit includes two sealing components. The two sealing components are respectively located on the left and right sides of the guide barrel 12 in the vertical projection and are symmetrically arranged along the guide barrel 12. The sealing component includes a heating element 43, a sealing element 41 and a plurality of suction cups 42. The sealing element 41 adopts a linear drive. The push rod of the sealing element 41 is horizontal and connected to the mounting seat 4 through a flange plate, which is used to drive the mounting seat 4 to slide left and right. The heating element 43 and the plurality of suction cups 42 are both installed on the mounting seat 4. Specifically, the plurality of suction cups 42 are distributed in sequence from front to back. The suction cups 42 in this embodiment are connected to an air pipe; the heating element 43 is located below the suction cup 42.

[0044] The clamping unit includes two clamping assemblies, which are respectively located at the front and rear sides of the guide barrel 12. The clamping assemblies include a transverse driving member 52, a slide rail 5 and a clamp 51. The slide rail 5 is installed on the frame from left to right by bolts. The clamp 51 is arranged on the slide rail 5 and slides with the slide rail 5. Specifically, the clamp 51 in this embodiment is a prior art. The two clamps 51 are respectively used to clamp the front and rear ends of the mouth of the packaging bag, and move the mouth of the packaging bag to between the suction cups 42 of the two sealing assemblies. During actual installation, the height of the clamp 51 is determined according to the position of the suction cup 42 to ensure that the mouth of the packaging bag can be opposite to the suction cups 42 of the two sealing assemblies when the packaging bag is clamped. The transverse driving member 52 also adopts a linear drive. The push rod of the transverse driving member 52 is connected to the clamp 51 through a flange plate, which is used to drive the clamp 51 to slide along the slide rail 5.

[0045] The support unit includes a support assembly and a vertical adjustment assembly. The vertical adjustment assembly includes an adjustment frame 2, a base frame 3 and a screw 21. The base frame 3 is arranged below the hopper 1. Both ends of the base frame 3 are vertically penetrated with vertical rods with interference fit. The upper ends of the vertical rods are connected to the frame by bolts to fix the base frame 3. The adjustment frame 2 is horizontally arranged above the base frame 3. The screw 21 vertically penetrates the adjustment frame 2 and has a clearance fit with the adjustment frame 2. Figure 5 As shown, a nut seat 25 is threadedly connected to the screw rod 21, and two V-shaped blocks 24 are installed on the adjustment frame 2 by bolts. The two blocks 24 are respectively located on both sides of the nut seat 25 and are both against the nut seat 25 to limit the nut seat 25. A shell 22 is sleeved on the screw rod 21, and the shell 22 is located above the adjustment frame 2, and a limit groove with an opening facing downward is provided in the shell 22. The shell 22 is covered on the two clamps and the nut seat 25, and bolts are installed on both ends of the shell 22. The bolts simultaneously penetrate the blocks 24 downward and are threadedly connected to the adjustment frame 2, and the shell 22 and the blocks 24 are fixed at the same time.

[0046] The lower end and upper end of the screw rod 21 are connected to the base frame 3 and the frame respectively through bearings. The lower key of the screw rod 21 is connected to the first bevel gear. The base frame 3 is rotatably provided with a second bevel gear, the second bevel gear is meshed with the first bevel gear, and the second bevel gear is coaxially connected to a handle 31, which can more conveniently rotate the screw rod 21.

[0047] The support assembly includes a support plate 6, a discharge member 23 and a connecting rod 61, which are arranged directly below the guide barrel 12. Specifically, the support plate 6 in this embodiment is lower than the sealing assembly and the clamping assembly, and is used to support the packaging bag that falls into the clamp. The support plate 6 in this embodiment is V-shaped. In actual implementation, the length of the left side wall of the support plate 6 can also be made greater than the length of the right side wall, so that when the support plate 6 rotates counterclockwise, the left side wall can be attached to the conveyor belt, so that the packaging bag on the support plate 6 can slide directly down along the left side wall to the conveyor belt below, further reducing the vibration of the clamp. The middle part of the connecting rod 61 is hinged with the adjustment frame 2, the left end is welded to the right side wall of the support plate 6, and the right end is provided with a strip groove along the axial direction, and a rotating shaft 62 is slidably connected in the strip groove. The discharge member 23 also adopts a linear drive, the push rod of the discharge member 23 faces downward, and the rotating shaft 62 horizontally penetrates the push rod of the discharge member 23, so that when the push rod of the discharge member 23 slides upward, it can push the connecting rod 61 to swing counterclockwise.

[0048] The specific implementation process is as follows:

[0049] The clamp to be packaged is placed on the turntable 7 and rotates with the turntable 7, passing through the camera, the first two blowing needles and the third blowing needle in sequence. When passing the camera, the camera takes a picture of the clamp and transmits the data to the controller, which determines whether the clamp is a qualified product or a defective product. When the clamp is judged to be a defective product, the third blowing needle blows air when the clamp rotates to align with the third blowing needle, blowing the clamp off the turntable 7. In actual implementation, a defective basket is set under the turntable 7 or the defective products are transported to the conveyor belt of the recycling process to collect the defective products. This embodiment will not be repeated. When the clamp is judged to be a qualified product, the statistical value of the counting module of the controller is increased by one, and when the clamp rotates to a relative position with the first two blowing needles, the blowing needle blows air, blowing the clamp from the turntable 7 to the conveyor belt 8 above the hopper 1, and the conveyor belt 8 is transported to the top of the hopper 1.

[0050] The clamp falls from the conveyor belt 8 onto the inclined surface 15, then slides down to the bottom of the hopper 1, and is restricted by the closing plate and stays in the hopper 1. At the same time, the transverse drive member 52 drives the clamp 51 to slide to the left, and after the clamp 51 clamps the mouth of the packaging bag, it drives the clamp 51 to reset to the right, clamping the mouth of the packaging bag between the two sealing components. Finally, the sealing member 41 is started, so that the suction cups 42 of the two sealing components are both against the mouth of the packaging bag, and then negative pressure is formed in the suction cup 42 through the air pipe to absorb the left and right side walls of the packaging bag, and then the mounting seat 4 is reset through the sealing member 41 to open the opening of the packaging bag.

[0051] When the value of the counting module reaches the preset value, it proves that the number of clamps in the hopper 1 reaches the packaging requirement of a packaging bag, and the guide barrel 12 is inserted downward into the packaging bag through the vertical pusher 11, and the controller controls the closing plate to slide out of the hopper 1, opens the guide barrel 1, and the clamp falls downward into the packaging bag. When all the clamps fall out, the controller controls the closing plate to slide into the hopper 1, closes the guide barrel 12, and the value of the counting module is reset. The guide barrel 12 is reset upward, and the lower end of the guide barrel 12 is separated from the packaging bag.

[0052] Then start the heating element 43, and slide the mounting base 4 toward each other through the sealing element 41 until the two heating elements 43 abut against each other to heat-seal the packaging bag. Since the mouth of the packaging bag is adsorbed on the suction cup 42 at this time, the mouth of the packaging bag is fully unfolded at this time, and the packaging bag can be heat-sealed more smoothly.

[0053] After the heat sealing is completed, air is ventilated into the suction cup 42 through the air pipe so that the suction cup 42 no longer absorbs the packaging bag. At the same time, the heating element 43 is turned off and the mounting seat 4 is reset in a direction away from each other so that the packaging bag is no longer fixed by the sealing assembly. When the clamp falls into the packaging bag, the bottom of the packaging bag falls on the support plate 6, and the clamp is protected and supported by the support plate 6, thereby preventing the packaging bag from being damaged by excessive weight. When the packaging bag is heat-sealed and the mounting seat 4 is reset in a direction away from each other, the push rod of the discharge member 23 is slid upward, driving the connecting rod 61 to rotate clockwise, so that the support plate 6 is tilted, and the packaging bag with the clamp is automatically dropped from the support plate 6. In actual implementation, a conveyor belt is set under the support plate 6 to convey the packaged packaging bag to the next process or warehouse.

[0054] When a larger packaging bag is needed for packaging, the handle 31 is turned to drive the screw 21 to rotate, and the adjustment frame 2 is slid downward to increase the distance between the support plate 6 and the material guide barrel 12; similarly, when a smaller packaging bag is needed for packaging, the adjustment frame 2 is slid upward to reduce the distance between the support plate 6 and the material guide barrel 12, ensuring that when the clamp falls into the packaging bag, the support plate 6 can be against the bottom of the packaging belt to support the packaging bag.

[0055] The above is only an embodiment of the present invention, and the common knowledge such as the known specific technical solutions and / or characteristics in the solution is not described in detail here. It should be pointed out that for those skilled in the art, without departing from the technical solution of the present invention, several modifications and improvements can be made, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicality of the patent. The scope of protection required by this application shall be based on the content of its claims, and the specific implementation methods and other records in the specification can be used to interpret the content of the claims.
