Description

Technical Field

[0001] The invention relates to the field of viscosity testing, and in particular to a glue pulling fracture height testing device for a glue dispensing machine. Background Art

[0002] The viscosity of dispensing is a very critical parameter in the dispensing process. It refers to the friction generated by the liquid sliding on another layer of liquid when it is subjected to external force. The thicker the liquid, the greater the internal friction and the greater the sliding resistance, while the opposite is true for thinner liquids. The viscosity of dispensing affects the flow rate, flow rate and bonding effect. Therefore, before dispensing, it is necessary to determine the viscosity of the liquid through testing, adjust the viscosity value according to actual production needs, and accurately measure and control it in order to better control the flow rate and flow rate of the liquid and ensure the quality and effect of dispensing. At the same time, for some glues with higher viscosity, it may also be necessary to control the temperature at the injection head to reduce the viscosity of the glue and improve the efficiency and accuracy of dispensing. The existing dispensing test method generally tests a single glue liquid first, and then replaces the glue sample. The overall test time is long and the efficiency is low. It is also easy to cause changes in environmental factors, affecting the test accuracy. Summary of the invention

[0012] Furthermore, the cover body also includes a third cover body which rotates with the center of the working column as the center of the circle and overlaps with the first cover body after rotating toward the first cover body;

[0013] The third cover body extends away from the side sliding groove of the first cover body until it overlaps with the first cover body, forming a third cover body limit platform in the same sliding manner as the second cover body limit platform, and the lower end of the third cover body limit platform is located in the sliding groove;

[0014] A third guide rail drivingly connected to the third cover body is provided on the working column at the upper cover position of the third cover body along the rotation path of the third cover body.

[0015] Furthermore, the third cover bodies include two, which are symmetrically arranged at two ends of the first cover body; each third cover body is provided with a sealing strip on one side close to each other, and a buffer pad on one side away from each other.

[0022] 1. The present invention can test the fracture height of multiple samples at the same time, and the fracture height comparison is more intuitive. When only a rough measurement is required, the viscosity difference of each sample can be compared and understood without precise measurements, which is convenient for directly replacing samples to continue testing and screening, and the test efficiency is high.

[0023] 2. When the absorption frame of the present invention rises, the through-beam sensor monitors whether the glue is connected. Once the glue is broken, the sensor generates a through-beam signal, and the degree head of the grating ruler measures the degree to obtain accurate data. At the same time, the first guide rail stops moving, and the break height difference of each sample can be observed and compared, which is intuitive and clear.

[0024] 3. The cover of the present invention can completely cover the test assembly to prevent environmental factors such as airflow from affecting the test sample. During the test interval, the second cover and the third cover can be rotated to fit with the first cover to facilitate the placement or replacement of samples in the sample tray.

[0025] 4. The sample of the present invention can be directly added to the sample plate, or it can be added through an external replaceable pipe, and the sample can be injected from the outside through the injection channel and the injection head after the cover is closed, which reduces the injection interval time and also avoids the first added sample from being affected by the airflow and impurities in the air to produce a certain degree of coagulation and contamination during the later addition, and avoids the influence of other factors on the test accuracy as much as possible. The sample plate is placed in the sample slot and is surrounded by an anti-slip ring, so it is firmly positioned during the test, and it is also easy to remove for cleaning and replacement, which is highly practical.

[0026] 5. The suction nozzle of the present invention can be removed together with the fixing plate, which is convenient for cleaning or replacement of the suction nozzle and avoids sample contamination; the suction nozzle is a hollow tube, which can use capillary action to generate additional attraction for the sample in the sample plate on the basis of its own viscosity, so as to infiltrate upward, thereby saving the cost of setting up an external suction device and avoiding errors easily caused by external suction.

[0027] 6. The fixing plate of the present invention is provided with a fastening nail to limit the rotation of the suction nozzle on the suction frame. At the same time, the pin in the fastening nail is interlocked with the limiting plate and the limiting groove, thereby limiting the movement of the suction nozzle in the up and down directions.

[0028] 7. The limiting plate and the limiting groove of the present invention are arranged in an arc shape, which can improve the locking stability and reduce the probability of the latch resetting itself without human operation. BRIEF DESCRIPTION OF THE DRAWINGS

A limiting slot 518 for inserting the limiting plate 516 and matching the limiting plate 516 is provided on the extraction frame 5 at the position of the limiting plate 516. The fastening nail 515 is provided with a channel 517 for the limiting plate 516 to pass through and which is connected with the limiting groove 518; when the latch 512 moves away from the limiting groove 518, the limiting plate 516 completely leaves the limiting groove 518 and is located in the channel 517; when the latch 512 moves close to the limiting groove 518, the limiting plate 516 is inserted into the limiting groove 518.

[0052] Preferably, Figure 4 As shown, the working column 11 is provided with a plurality of injection channels 3 with upper openings in the axial direction; the working column 11 at the lower end of each injection channel 3 is provided with a sample placement head 31 spaced from the absorption rack 5.

[0053] Preferably, a turntable 43 is provided on the working column 11 of the workbench 1 at the position of the sample plate 41, and a rotary drive 44 for driving the turntable 43 is provided below the turntable 43. A sample groove 4 matching the sample plate 41 is provided on the upper surface of the turntable 43. An anti-slip ring 42 is provided on the inner wall of the edge of the upper opening of the sample groove 4.

[0054] Based on the above structure, the present invention is a device for testing the fracture height of glue pulling for glue dispensing machines. Before the test, a clean sample plate 4 is placed on the sample groove 4 and is stuck by the anti-slip ring 42. The second guide rail 223 and the third guide rail 233 respectively drive the upper covers of the second cover body 22 and the third cover body 23 to rotate toward each other, and at the same time, the pulley 24 at the pulley groove 241 rotates, which reduces the friction resistance of the cover body movement and limits the axial and radial movement of the cover body. The second cover body 22 and the third cover body 23 are gradually unfolded until the third cover bodies 23 on both sides meet, and each cover body forms a whole, covering the working column 11, the extraction frame 5 and the sample plate 41; the sealing rings 232 of the third cover bodies 23 on both sides are close to each other, and the brushes 221 on both sides of the second cover body 22 respectively seal the gaps between the second cover body 22 and the first cover body 2 and the third cover body 23. The rotary drive 44 rotates the turntable 43 until the center of the sample plate 41 is located directly below the sample outlet nozzle 33; a replaceable delivery tube is inserted into the sample inlet channel 3 until the lower end of the delivery tube reaches the lower end of the sample outlet nozzle 33, and then a certain amount of glue is injected into the delivery tube, and the glue falls into the sample plate 41. After the sample glue is placed, the turntable 43 continues to rotate until the suction nozzle 52 reaches directly above the sample plate 41; the first guide rail 55 drives the suction frame 5 to move downward, and the lower end of the suction nozzle 52 is immersed in the glue in the sample plate 41. After dipping the glue, the first guide rail 55 drives the suction frame 5 to move upward. During the movement, when the glue breaks, the cross-shooting sensor loses the barrier of the glue, receives the cross-shooting signal, and the first guide rail 55 stops moving, and the grating ruler records the height data to complete the test. If the cover is made of transparent material, the height of the sample can be observed through the cover. If the cover is opaque, the cover needs to be opened for observation.

[0055] When the test is completed or the sample needs to be replaced, the second guide rail 223 and the third guide rail 233 respectively drive the upper covers of the second cover body 22 and the third cover body 23 to rotate and open toward the first guide rail 2 until the second cover body limit platform 221 touches the buffer pad 211 on the first cover body 2, and the third cover body limit platform 231 touches the brush 222 on the second cover body 22, and the three covers overlap with each other, exposing the covered working column 11, the suction rack 5 and the sample placement plate 41.

[0056] The handle 511 of the latch 512 is gently lifted to tilt the upper end of the latch 512 away from the limiting groove 518, and the limiting plate 516 at the lower end of the latch 512 is tilted in the limiting groove 518. Then, the upper end of the latch 512 is kept away from the limiting groove 518, and the latch 512 is pushed to move the lower end of the latch 512 away from the limiting groove 518. The limiting plate 516 leaves the limiting groove 518 and is located in the channel 517. The fixing plate 51 is lifted upward to pull out the fastening nail 515 and the suction nozzle 52. After cleaning or replacing the suction nozzle 52, the fixing plate 51 is inserted back into place, and the latch 512 is operated in reverse to complete the pin lock. The sample tray 41 and the delivery tube in the injection channel 3 can be taken out for cleaning and replacement.

[0057] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in this field without departing from the purpose of the present invention.
