As shown in fig. 3, the present invention provides an automatic feeding and discharging machine, which is matched with a feeding conveyor belt 81 and a discharging conveyor belt 82 in a production line, so as to realize automatic feeding and discharging of products loaded in a pressure maintaining fixture 9 shown in fig. 1 and 2 for equipment such as a dispensing machine. The specific structure of the pressure maintaining clamp 9 is described in the following, and the structure and working process of the automatic feeding and discharging machine are described in detail.
The pressure maintaining clamp 9 comprises a base 90 and a pressure maintaining cover 91, a product is placed on the base 90, and the pressure maintaining cover 91 is buckled on the base 90 in a butt joint mode. A side wing 92 is pivotally connected to each of both sides of the base 90, and when the side wing 92 is erected, an inner portion thereof is pressed against the holding cover 91, so that the holding cover 91 is held under pressure. A gap 93 is provided between the raised side wing 92 and the base 90, and the holding jig 9 can be grasped and moved by the gap 93.

Referring to fig. 3 to 5, the automatic loading and unloading machine includes a frame 1, a material moving mechanism 2 arranged in the frame 1, a temporary storage device 3, a robot 4, and a loading and unloading mechanism 5 mounted on the robot 4. The lower part of the frame 1 is closed, in which necessary electrical and control components are accommodated, and the front end of the upper part of the frame 1 is open to facilitate observation of the working state of the mechanism therein. The feeding conveyor belt 81 and the discharging conveyor belt 82 pass through the frame 1 in the left-right direction of the frame 1. The temporary storage device 3 comprises a stock plate 31 positioned between the feeding conveyer belt 81 and the discharging conveyer belt 82, the extending direction of the stock plate 31 is approximately perpendicular to the conveying directions of the two conveyer belts, and two ends of the stock plate 31 respectively abut against the two conveyer belts, and can be in direct contact or not in contact. The position of the transfer mechanism 2 is close to the feeding conveyor belt 81 and moves the holding jigs 9 conveyed from the feeding conveyor belt 81 one by one onto the stock plate 31. The pressure maintaining clamp 9 on the stock plate 31 is pushed to one end close to the blanking conveyer belt 82 by the temporary storage device 3, and then the pressure maintaining clamp 9 is fed into the dispenser by the robot 4 and the feeding and discharging mechanism 5.
The feeding conveyor belt 81 is provided with a detection sensor 83 and two opposite positioning cylinders 84 at a position close to the material moving mechanism 2, and when the pressure maintaining clamp 9 is detected to arrive, the two positioning cylinders 84 position the pressure maintaining clamp 9 so as to take materials by the material moving mechanism 2. The positioning cylinder 84 performs a function of temporarily positioning the holding jig 9, and may be replaced with other positioning mechanisms such as a movable shutter or the like. The robot 4 in this embodiment is a three-axis robot, and includes two longitudinal rails 41, a transverse rail 42 connected between the two longitudinal rails 41, and a vertical rail 43 mounted on the transverse rail 42, wherein the transverse rail 42 runs substantially parallel to the two conveyor belts. The robot 4 is used for realizing the movement of the feeding and discharging mechanism 5, the structure is not limited to the slide rail type structure, and may be a swing arm type structure, and the degree of freedom is determined by the actual movement requirement of the feeding and discharging mechanism 5, and may be two shafts or even one shaft in other embodiments.
As shown in fig. 6, the material transfer mechanism 2 includes a transverse driving device which spans over one end of the feeding conveyor 81 and one end of the stock plate 31, and a material transfer seat 20 which is driven by the transverse driving device, and a clamping jaw 21 which can clamp the pressure maintaining clamp 9 is installed under the material transfer seat 20. When the two clamping jaws 21 are folded, the clamping jaws 21 can be inserted into the gaps 93 under the wings 92 on the two sides of the pressure maintaining clamp 9, so that the pressure maintaining clamp 9 is grabbed. Specifically, the transverse driving device is a rodless cylinder comprising a cylinder 22 and a slide 23, the cylinder 22 is mounted on a stand 24, and a guide rod 25 for guiding and reinforcing the slide 23 is provided on the stand 24. A sliding table 26 which moves along the vertical direction is fixed on the sliding block 23, the material moving seat 20 is fixed on the sliding table 26 so as to move up and down, and the clamping jaw 21 is driven by a clamping jaw air cylinder 27.
The product has direction requirement during dispensing, so the pressure maintaining clamp 9 conveyed by the feeding conveyor belt 81 also needs to be clearly oriented. Referring to fig. 5 and 6, a calibration sensor 60 is disposed on the stock plate 31 adjacent to the feeding conveyor 81, and a turning device 28 is installed under the transfer base 20, and a jaw cylinder 27 is fixed under the turning device 28 and can be driven by the turning device 28 to rotate 180 degrees. After the clamping jaw 21 grabs the pressure maintaining clamp 9, the pressure maintaining clamp 9 is moved to the position above the check sensor 60, if the direction of the pressure maintaining clamp 9 is correct, the check sensor 60 is opposite to the check hole 95 on the pressure maintaining clamp 9, no signal is received, and if the direction of the pressure maintaining clamp 9 is not opposite, the check sensor 60 receives the signal. At this time, the turning device 28 drives the clamping jaw air cylinder 27 and the clamping jaw 21 to rotate 180 degrees, so that the direction of the pressure maintaining clamp 9 is correct. The turning device 28 is in particular a turning cylinder.
Referring to fig. 7 and 8, the temporary storage device 3 further includes a pushing mechanism disposed under the stock plate 31 and pushing the pressure maintaining fixture 9 to a position close to one end of the blanking conveyor 82. Two sides of the stock plate 31 are respectively fixed with a limit strip 32, and the pushing mechanism pushes the pressure maintaining clamp 9 to slide between the two limit strips 32. The pushing mechanism comprises a power device 33, a pushing plate 34 which is driven by the power device 33 to slide relative to the stock plate 31, and a pushing piece 35 which is pivoted on the pushing plate 34 in a one-way swinging manner. The pushing plate 34 is located below the stock plate 31, the stock plate 31 is provided with a long groove 310 extending along the length direction, and one end of the pushing member 35 on the pushing plate 34 is exposed from the long groove 310. Specifically, there are two elongated slots 310, and the plurality of pushing members 35 on the pushing plate 34 are arranged in two rows and are exposed from the two elongated slots 310 respectively. The middle part of the pushing member 35 is pivoted on the pushing plate 34, one end, close to the feeding conveyer belt 81, of the pushing member 35 below the stock plate 31 abuts against the pushing plate 34, one end, exposed on the stock plate 31, of the pushing member 35 is provided with an inclined surface 351 facing the feeding conveyer belt 81, and one end, exposed on the stock plate 31, facing the discharging conveyer belt 82 is a vertical plane 352. When the pushing plate 34 moves towards the discharging conveyor belt 82, the pushing piece 35 cannot swing, and the pushing piece 35 can push the pressure maintaining clamp 9 to slide towards one side of the discharging conveyor belt 82 on the storage plate 31; when the pushing plate 34 moves toward the feeding conveyor 81, the contact between the inclined surface 351 and the pressure maintaining clamp 9 drives the pushing member 35 to swing, so that the pushing member 35 does not push the pressure maintaining clamp 9 reversely. Therefore, the pushing mechanism in the temporary storage device 3 can push the pressure maintaining clamp 9 to one side of the feeding conveyor belt 82. The power device 33 may be a motor, a cylinder, or the like.
As shown in fig. 9 and 10, the loading and unloading mechanism 5 includes a fixed base 50 fixed to the robot 4 and two gripping members 51 for butt-fixing with both side ends of a pressure maintaining cover 91 of the pressure maintaining jig 9. Specifically, a material grabbing driver 52 and two sliding plates 53 driven by the material grabbing driver 52 to slide horizontally are arranged on the top surface of the fixed seat 50, and the sliding plates 53 are fixed with the sliding pieces 54 and slide by means of the rails 55. The two gripping members 51 are respectively connected to the outer sides of the two sliding plates 53 and extend downward, preferably in an elastic connection manner, and the gripping needles 511 extending inward are fixed at the lower ends of the gripping members 51, and the gripping needles 511 can be inserted into the gripping holes 94 on the side surfaces of the holding cover 91, and the number of the gripping holes 94 on the holding cover 91 is known to be two, so that the number of the gripping needles 511 is also two. The two grabbing pieces 51 are driven by the grabbing driver 52 to be relatively opened, then the grabbing pieces 51 are moved to the pressure maintaining clamp 9 to enable the grabbing needles 511 to be aligned with the grabbing holes 94, after the two grabbing pieces 51 are folded, the grabbing needles 511 are inserted into the grabbing holes 94, and then the loading and unloading mechanism 5 can lift the pressure maintaining cover 91. Note that, since the side wings 92 press against the holding cover 91, the entire holding jig 9 is lifted when the holding cover 91 is lifted.
Referring to fig. 10 to 12, the loading and unloading mechanism 5 needs to realize the function of removing and covering the holding cover 91 in addition to the loading and unloading function. Therefore, the loading and unloading mechanism 5 further comprises an outer support assembly 7 and an inner retraction assembly 8 which are arranged below the fixed seat 50.
The outer support assembly 7 comprises an outer support driving member 71, an outer support sliding member 72 and two outer support rods 73 pivoted into a cross structure, wherein the two outer support rods 73 are pivoted to the fixed seat 50 through a middle pin 74, the outer support driving member 71 is an air cylinder and is fixed on the bottom surface of the fixed seat 50, one end of the outer support sliding member 72 is connected with the outer support driving member 71, the other end of the outer support sliding member 72 is pivoted with two linkage members 75, and the two linkage members 75 are respectively pivoted to the two outer support rods 73. An outer strut 76 is provided at each end of each outer strut 73, the outer strut 76 preferably being wheel-shaped and rotatable on the outer strut 73. The outer stay sliding member 72 is driven to slide by the outer stay driving member 71 and causes the two outer stay bars 73 to be folded or unfolded in the sliding direction thereof. When the two outer stay bars 73 are in the folded state, the projection length of the two outer stay bars 73 in the sliding direction of the outer stay sliding member 72 is smaller than the interval between the two raised side wings 92 in the pressure maintaining clamp 9, so that the outer stay members 76 can be inserted between the two side wings 92, and when the two outer stay bars 73 are unfolded, the two side wings 92 are unfolded by the four outer stay members 76 which are far away from each other, so that the side wings 92 are separated from the pressure maintaining cover 91. The number of the outer stay 76 is not necessarily four, and the outer stay 76 on the same side as the outer stay 72 may be provided only at one end of the two outer stay 73.
The adduction assembly 8 comprises an adduction driving member 81, a first adduction sliding member 82, a second adduction sliding member 83, and a linkage rod group 84 connected between the first adduction sliding member 82 and the second adduction sliding member 83. The adduction driving member 81 is a cylinder fixed on the front surface of the fixed seat 50, and the adduction driving member 81 is fixed with the first adduction sliding member 82 through a connecting member 80 and drives the first adduction sliding member 82 to slide, and the sliding direction of the first adduction sliding member 82 is parallel to the sliding direction of the outer supporting sliding member 72. The plurality of rods in the linkage rod set 84 are pivoted to a cross folding structure, and the middle part of the linkage rod set 84 is pivoted to the fixed seat 50 through an outer pin 86, so that the second adduction sliding piece 83 is driven to be close to or far from the first adduction sliding piece 82 through the linkage rod set 84 when the first adduction sliding piece 82 slides. An inner folding piece 88 is respectively arranged on the first inner folding sliding piece 82 and the second inner folding sliding piece 83, the outer supporting piece 76 is positioned between the two inner folding pieces 88, and the distance between the two inner folding pieces 88 is larger than the distance between the two standing side wings 92 on the pressure maintaining clamp 9. When the two inner receiving members 88 are moved toward each other, the two already opened side wings 92 of the pressure maintaining jig 9 can be swung inward and re-erected to be pressed against the pressure maintaining cover 91.
Preferably, the number of the inner assemblies 8 is two, and the two inner assemblies 8 are respectively located at two sides of the outer supporting assembly 7, and the front ends of the second inner sliding parts 83 of the two inner assemblies 8 are fixedly connected through a connecting rod 89, so that the synchronism and the stability are improved.
It should be noted that, with reference to the angle in fig. 11, the positions of the two outer struts 73 are higher than the position of the linkage rod set 84, so that the actions of the outer strut assembly 7 and the inner strut assembly 8 do not interfere at all. Further, the position of the grasping needle 511 on the grasping member 51 is higher (lower in the actual position) than the outer stay assembly 7 and the inner retraction assembly 8, so that the grasping operation of the grasping member 51 on the pressure retaining cover 91 and the opening and closing operations of the outer stay assembly 7 and the inner retraction assembly 8 on the side wings 92 do not interfere at all.
Referring to fig. 4 again, the number of vertical sliding rails 43 provided on the transverse sliding rails 42 in the triaxial robot 4 is two, and the number of the feeding and discharging mechanisms 5 in the automatic feeding and discharging machine is also two, and the two feeding and discharging mechanisms 5 are respectively installed on the two vertical sliding rails 43. The purpose of arranging two feeding and discharging mechanisms 5 is to match a plurality of dispensing stations on the adhesive dispensing machine, which is beneficial to improving the efficiency, but the automatic feeding and discharging machine can realize the functions of the automatic feeding and discharging machine by only comprising one feeding and discharging mechanism 5.
The working process of the automatic feeding and discharging machine is described below by combining with a proper drawing, and for convenience of understanding, the two automatic feeding and discharging mechanisms 5 are divided into a first feeding and discharging mechanism 5 and a second feeding and discharging mechanism 5.
The first feeding and discharging mechanism 5 inserts the grabbing needle 511 of the grabbing piece 51 into the grabbing hole 94 on the pressure maintaining cover 91 of the first pressure maintaining clamp 9, the first pressure maintaining clamp 9 is fed to the glue dispenser, then the outer supporting component 7 of the first feeding and discharging mechanism 5 acts to open the two side wings 92 of the first pressure maintaining clamp 9, then the first feeding and discharging mechanism 5 retreats and brings the pressure maintaining cover 91 down, and the glue dispenser performs glue dispensing. After the second feeding and discharging mechanism 5 retreats, the second pressure maintaining clamp 9 is grabbed, the second pressure maintaining clamp 9 is fed to the glue dispenser, the pressure maintaining cover 91 is taken down, the second feeding and discharging mechanism 5 places the pressure maintaining cover 91 on the second pressure maintaining clamp 9 on the base 90 of the first pressure maintaining clamp 9 after glue dispensing is completed, and then the first pressure maintaining clamp 9 is fed to the discharging conveyor belt 82. The second loading and unloading mechanism 5 grabs the third pressure maintaining clamp 9 for loading, and at the same time, the first loading and unloading mechanism 5 covers the pressure maintaining cover 91 of the original first pressure maintaining clamp 9 onto the base 90 of the second pressure maintaining clamp 9, and then the second pressure maintaining clamp 9 is unloaded. The way is reciprocated, so that the product is ensured to be subjected to the glue dispensing process every time of blanking, and the efficiency is ensured. In the loading and unloading process, the pressure maintaining cover 91 of each pressure maintaining clamp 9 is covered on the base 90 of the last pressure maintaining clamp 9 after dispensing, so the last pressure maintaining clamp 9 will not have the pressure maintaining cover 91, and therefore a pre-storing position 15 adjacent to the stock plate 31 is set on the frame 1, as shown in fig. 4, a pressure maintaining cover 91 is pre-stored on the pre-storing position 15, and the pressure maintaining cover 91 can be covered on the last pressure maintaining clamp 9.
The automatic feeding and discharging machine not only can realize automatic feeding and discharging of the pressure maintaining clamp 9, but also can simultaneously execute actions of taking down or covering the pressure maintaining cover 91, thereby being beneficial to improving the efficiency of operation procedures such as dispensing and ensuring the dispensing effect.
Preferably, a discharging conveyor belt 85 crossing over the feeding conveyor belt 81 is further provided in the automatic feeding and discharging machine, and when defective products are found in the dispensing process, the defective products are placed on the discharging conveyor belt 85 to be discharged.
The foregoing disclosure is illustrative of the present invention and is not to be construed as limiting the scope of the invention, but is for the convenience of those skilled in the art to understand and practice the invention, and therefore, equivalent variations to the appended claims are intended to be encompassed by the present invention.
