Description

Technical Field

[0001] The present application relates to the technical field of dispensing machines, and more particularly to a positioning mechanism and a dispensing machine having the positioning mechanism. Background Art

[0002] A dispensing machine, also known as a glue coating machine, a drop glue machine, a glue injection machine, a potting machine, etc., is specifically used to control fluids. It is an automated machine that can drip and coat fluids on the surface or inside of products, and can achieve three-dimensional and four-dimensional path dispensing, precise positioning, accurate glue control, no wire drawing, no glue leakage, and no glue dripping.

[0003] Refer to Figure 1 There is a magnetic material after bonding of a magnetic block and a magnetic block. The magnetic block is in the shape of a cuboid as a whole, and now it is necessary to bond multiple magnetic blocks into a long magnetic material. Currently, the dispensing machines used for bonding magnetic blocks usually use a manipulator to adsorb and move. The magnetic block moves on the conveying track to the adsorption area, and then the manipulator adsorbs and lifts the magnetic block from the conveying track. The adsorbed magnetic block is smeared with glue on the surface by a glue dispensing mechanism, and then the manipulator drives the magnetic block to move to the blanking area. Repeat the above operations to stack multiple magnetic blocks in the height direction, so that the magnetic blocks are bonded into a long strip-shaped magnetic material.

[0004] In view of the above related technologies, the magnetic blocks have different postures when moving on the conveying track, resulting in an interleaved situation when the manipulator stacks them, so that adjacent magnetic blocks cannot fit together. Utility Model Content

[0005] In order to ensure that the magnetic blocks adsorbed by the manipulator are in the same posture, the present application provides a positioning mechanism and a dispensing machine having the positioning mechanism.

[0006] The positioning mechanism and the dispensing machine having the positioning mechanism provided by the present application adopt the following technical solutions:

[0007] A positioning mechanism includes a positioning table, a first pushing member for pushing a magnetic block from a conveying track to the positioning table, and a second pushing member provided on one side of the positioning table. The pushing directions of the first pushing member and the second pushing member are perpendicular to each other. The positioning table is provided on one side of the conveying track, and positioning strips for positioning and abutting against adjacent sides of the magnetic block are provided on the top of the positioning table.

[0008] By adopting the above technical solutions, the magnetic block is pushed from the conveying track to the positioning table by the first pushing member, and then the other side of the magnetic block is pushed by the second pushing member, so that the adjacent sides of the magnetic block are respectively abutted against the positioning strips, realizing the positioning of the magnetic block, ensuring that the magnetic blocks adsorbed by the manipulator are all in the same position, and improving the accuracy of the manipulator.

[0009] Optionally, the positioning member includes a first positioning strip and a second positioning strip. The first positioning strip is located on the side of the positioning table away from the conveying track and corresponds to the pushing direction of the first pushing member, and the second positioning strip corresponds to the pushing direction of the second pushing member.

[0010] By adopting the above technical solution, the composition of the positioning member is specifically disclosed. The first positioning strip and the second positioning strip are arranged vertically. The first pushing member first pushes the magnetic block to abut against the first positioning strip, and then the second pushing member pushes the magnetic block to abut against the second positioning strip. The assembly of the above positioning strips is simple, and the positioning effect of the magnetic block is relatively ideal.

[0011] Optionally, the first pushing member includes a first air cylinder and a first pushing block, and the second pushing member includes a second air cylinder and a second pushing block connected to the output shaft of the second air cylinder; the first pushing block includes a driving block connected to the output shaft of the first pushing block, a pushing block for pushing the magnetic block, and a connecting plate connecting the driving block and the pushing block.

[0012] By adopting the above technical solution, the structural compositions of the first pushing member and the second pushing member are disclosed. The structures of the above two pushing members are simple, the assembly is convenient, and the pushing efficiency for the magnetic block is relatively ideal.

[0013] Optionally, the connecting plate is provided with a strip-shaped hole penetrating through both side walls, and a locking member for connecting the pushing block and the driving block is arranged in the strip-shaped hole.

[0014] By adopting the above technical solution, the setting of the strip-shaped hole can adjust the positions of the driving block and the pushing block, so as to adapt to magnetic blocks of different sizes for positioning.

[0015] Optionally, a plurality of positioning ridges are arranged on the top of the positioning table, and the plurality of positioning ridges are arranged at intervals and parallel to each other along the pushing direction of the second pushing member.

[0016] By adopting the above technical solution, the setting of the positioning ridges reduces the contact area between the magnetic block and the positioning table when the magnetic block moves on the positioning table, reduces the friction force, thus making it easier to push the magnetic block, and plays a protective role for the magnetic block, reducing the wear caused when the magnetic block is pushed.

[0017] Optionally, one end of the positioning ridge close to the conveying track has a guiding inclined surface for guiding the movement of the magnetic block, and the guiding inclined surface inclines downward towards the conveying track.

[0018] By adopting the above technical solution, the setting of the guiding inclined surface can play a guiding role in moving the magnetic block to the top of the positioning table and improve the pushing efficiency of the magnetic block.

[0019] Optionally, a guide plate for guiding the movement of the magnetic block is provided along the conveying direction of the conveying track. The guide plate and the side wall of the conveying track form a guiding chute, and the radial width of the guiding chute gradually decreases towards the positioning table.

[0020] By adopting the above technical solution, the guiding chute formed by the guide plate and the conveying track can adjust the attitude of the magnetic block during conveying, ensuring that the attitudes of the magnetic blocks are consistent when they are conveyed to one side of the positioning table, and improving the pushing efficiency.

[0021] Optionally, it further includes an abutting block arranged at the end of the conveying track and a sensor arranged on the abutting block and used for detecting the magnetic block. When the magnetic block abuts against the abutting block, the sensor transmits a signal to the control mechanism to drive the conveying track to stop conveying and drive the first pushing member to start.

[0022] By adopting the above technical solution, the arrangement of the abutting block can play a role in limiting the conveying of the magnetic block on the conveying track. The sensor can monitor the magnetic block that abuts against the abutting block and control the pushing of the first pushing member and the second pushing member, improving the bonding efficiency of the magnetic block.

[0023] A dispensing machine includes the above-mentioned positioning mechanism, a working platform, a conveying track arranged on the working platform and used for conveying magnetic blocks, a grasping mechanism and a glue dispensing mechanism arranged on the working platform.

[0024] By adopting the above technical solution, the dispensing machine adopts the above-mentioned positioning mechanism, which can position the magnetic block before adsorption and ensure the accuracy when the grasping mechanism discharges the magnetic block.

[0025] Optionally, the glue dispensing mechanism includes a glue dispensing seat, a driving pump and a return pipe. An adhesive column communicating with the driving pump is arranged at the top of the glue dispensing seat. The glue dispensing seat has a glue groove outside the adhesive column, and a return hole communicating with the return pipe is opened at the bottom wall of the glue groove.

[0026] By adopting the above technical solution, the composition of the glue dispensing mechanism is disclosed. When the grasping mechanism adsorbs the magnetic block, it moves to the top of the glue dispensing seat, and then horizontally moves the magnetic block along the adhesive column, so that the bottom of the magnetic block adheres to the glue.

[0027] Optionally, the glue dispensing seat and the magnetic block positioned in the positioning area are on the same axis in the conveying direction.

[0028] By adopting the above technical solution, the setting of the air jet structure can clean the magnetic blocks on the conveying track, reduce the dust and impurities on the surface of the magnetic blocks, and improve the adsorption effect of the grasping mechanism on the magnetic blocks.

[0029] In summary, the present application includes at least one of the following beneficial technical effects:

[0030] 1. By providing a positioning table, a first pusher, a second pusher, and a positioning member, the present application can achieve a positioning effect on the magnetic block, ensuring an ideal flatness after the magnetic block is bonded.

[0031] 2. By providing positioning ridges, the present application can reduce the contact area between the magnetic block and the positioning table, reduce friction, and at the same time reduce wear caused when the magnetic block is pushed.

[0032] 3. By providing a guide plate, the present application can adjust the posture of the magnetic block during transportation, ensuring that the postures of the magnetic blocks are consistent when they are transported to one side of the positioning table. Description of the Drawings

Detailed Embodiments

[0039] The following further describes the present application in detail Figure 2-5 in conjunction with the appended drawings.

[0040] An embodiment of the present application discloses a positioning mechanism and a dispensing machine having the positioning mechanism.

[0041] Referring to Figure 2 and Figure 3, A dispensing machine, including a working platform 1, on which a conveying track 2 for conveying magnetic blocks, a positioning mechanism for positioning the magnetic blocks, and a grasping mechanism 3 for adsorbing the magnetic blocks are installed. The conveying track 2 is a belt conveying structure in the prior art. One end of the conveying track 2 is defined as the feeding end, and the other end is defined as the discharging end. The grasping mechanism 3 is a common automatic palletizing manipulator in the prior art.

[0042] The positioning mechanism is arranged at the discharging end of the conveying track 2, and it includes a positioning table 4, a first pushing member 5, a second pushing member 6, and a positioning member 7. The positioning table 4 is bolted to one side of the discharging end, and the side plate of the conveying track 2 has a communication notch 21 corresponding to the positioning table 4. The first pushing member 5 pushes one side in the length direction of the magnetic block, and the second pushing member 6 pushes one side in the width direction of the magnetic block.

[0043] A plurality of positioning ridges 41 are fixedly installed on the top of the positioning table 4. The top surface height of the positioning ridges 41 is equal to or lower than the top surface of the conveying track 2. The positioning ridges 41 are arranged along the pushing direction of the first pushing member 5. The plurality of positioning ridges 41 are arranged at intervals and in parallel along the pushing direction of the second pushing member 6, so as to reduce the friction force when the magnetic block is pushed and improve the pushing effect. Among them, the positioning ridge 41 has a guiding inclined surface 411 at the end facing the conveying track 2, and the guiding inclined surface 411 inclines downward towards the conveying track 2.

[0044] The positioning member 7 includes a first positioning strip 71 and a second positioning strip 72, and the first positioning strip 71 and the second positioning strip 72 are arranged perpendicularly. Among them, the first positioning strip 71 corresponds to the pushing direction of the first pushing member 5, and the second positioning strip 72 corresponds to the pushing direction of the second pushing member 6. Under the pushing of the first pushing member 5 and the second pushing member 6, the adjacent two sides of the magnetic block are positioned and abutted against the two positioning strips, realizing the attitude adjustment of the magnetic block.

[0045] Combined with Figure 4 , the first pushing member 5 includes a first air cylinder 51 and a first pushing block 52 connected to the output shaft of the first air cylinder 51. The output shaft of the first air cylinder 51 is perpendicular to the extending direction of the conveying track 2. The first pushing block 52 is an overall L-shaped pushing block, which includes a driving block 521 connected to the first air cylinder 51, a pushing block 522 arranged perpendicularly to the driving block 521, and a connecting plate 523 connecting the driving block 521 and the pushing block 522. The connecting plate 523 is an L-shaped plate member, which is fixed to the driving block 521 and the pushing block 522 respectively through locking members, and the locking members are bolts. The connecting plate 523 is provided with strip-shaped holes 5231 corresponding to the driving block 521 and the pushing block 522 respectively, and the strip-shaped holes 5231 are arranged along the extending direction of the driving block 521 or along the extending direction of the pushing block 522, so as to be able to adjust the horizontal position of the pushing block 522 to adapt to magnetic blocks of different sizes.

[0046] The pushing block 522 is entirely located above the conveying track 2. The second pushing member 6 includes a second air cylinder 61 and a second pushing block 62 connected to the output shaft of the second air cylinder 61. The second pushing block 62 corresponds to the second positioning strip 72. After the first air cylinder 51 is activated, the pushing block 522 can horizontally push the magnetic block from the conveying track 2 to the positioning table 4 and abut against the first positioning strip 71, and then the magnetic block is pushed by the second air cylinder 61 to abut against the second positioning strip 72.

[0047] A guiding plate 22 is fixedly installed on the conveying track 2 along the extending direction. A guiding slideway 23 for conveying the magnetic block is formed on one side of the guiding plate 22 and the conveying track 2 facing the positioning table 4. The radial width of the guiding slideway 23 gradually decreases from the feeding end to the discharging end to ensure that the magnetic block can be conveyed in a posture with its length direction parallel to the sliding direction.

[0048] To improve the pushing efficiency, a butting block 24 and a sensor 25 arranged on the butting block 24 are further provided at the discharging end of the conveying track 2. The butting block 24 is located on the side of the pushing block 522 away from the feeding end. After the magnetic block abuts against the butting block 24, the sensor 25 transmits a signal to the control mechanism of the working platform 1, and the control mechanism is a PLC or other automatic control unit. The control mechanism drives the conveying track 2 to stop conveying, and at the same time activates the first pushing member 5 to push the magnetic block. After the magnetic block is adsorbed and lifted, the first pushing member 5 resets and the conveying track 2 is restarted.

[0049] Refer to Figure 4 and Figure 5 As shown in, a glue dispensing mechanism 8 for applying glue is installed on one side of the discharging end of the conveying track 2 of the working platform 1. The glue dispensing mechanism 8 includes a glue dispensing base 81, a driving pump 82 and a return pipe 83. A glue dispensing column 811 with an open top is arranged at the top of the glue dispensing base 81. The glue dispensing column 811 is communicated with the driving pump 82 through a pipeline so that the driving pump 82 can convey the glue upward to the top of the glue dispensing column 811.

[0050] The glue dispensing base 81 has a glue groove 812 outside the glue dispensing column 811. A return hole 813 is opened on the bottom wall of the glue groove 812. The return hole 813 is communicated with the return pipe 83 so that the glue overflowing from the glue dispensing column 811 flows back to the container containing the glue through the return hole 813.

[0051] The implementation principle of a dispensing machine in an embodiment of this application is as follows: The magnetic block is conveyed from the feeding end to the discharging end under the action of the guiding plate 22; when the magnetic block abuts against the abutting block 24, the conveying track 2 stops conveying, and the first pushing member 5 is activated; the pushing block 522 pushes the magnetic block from the conveying track 2 to the positioning table 4 and abuts against the first positioning strip 71, and then the second pushing member 6 is activated, and the second air cylinder 61 pushes the magnetic block to abut against the second positioning strip 72 to realize the positioning of the magnetic block; the grasping mechanism 3 adsorbs and lifts the magnetic block and moves it to the glue outlet column 811, the magnetic block slides past in contact with the top of the glue outlet column 811, and finally the magnetic block is moved to the placing area on one side of the conveying track 2 for stacking, so that two magnetic blocks in the height direction are bonded.

[0052] The above are all preferred embodiments of this application, and the protection scope of this application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
