Description

Technical Field

[0001] The utility model relates to the technical field of industrial potting adhesives, in particular to a glue feeding device. Background Art

[0002] In the existing industrial production, it is often necessary to use glue injection equipment to inject some colloidal fluids onto the working surface or into some small gaps. During the working process of the glue injection equipment, an additional glue feeding device is required to ensure that the glue injection equipment can continue to work.

[0003] The existing glue feeding device includes a plunger pump, a lifting device and a pressure plate. The plunger pump is arranged at the lifting end of the lifting device, and the lifting device is configured to control the lifting of the plunger pump. The pressure plate is fixed on the plunger pump. Under the action of the lifting device, the plunger pump is inserted into the glue bucket, and the pressure plate continuously presses down on the glue surface. Through the pressure of the pressure plate and the reciprocating movement of the plunger pump, the glue is transported to the glue injection device through the feeding pipeline. Since the viscosity of the glue in the glue bucket is relatively high, it is easy to have glue residues at the bottom of the pressure plate. It is necessary to regularly remove the pressure plate from the plunger pump and clean the waste attached to the pressure plate, which increases the workload of the staff. In addition, if there is residual glue when cleaning the waste, resulting in waste, it is easy to cause the pipeline to be blocked during glue feeding of the glue feeding device, further increasing the workload of the staff.

Among them, by way of example, direct connection means that two parts or components are connected together without the need for an intermediate member, and indirect connection means that two parts or components are respectively connected to at least one intermediate member, and these two parts or components are connected through the intermediate member. In addition, "connect" and "couple" are not limited to physical or mechanical connection or coupling, and can include electrical connection or coupling.

[0053] In this application, those of ordinary skill in the art will understand that relative terms used in connection with a quantity or condition (e.g., "about", "approximately", "substantially", etc.) are intended to include the recited value and have the meaning indicated by the context. For example, such relative terms include at least the degree of error associated with the measurement of a particular value, tolerances resulting from manufacturing, assembly, use in relation to a particular value, etc. Such terms should also be considered to disclose a range defined by the absolute values of two endpoints. The relative term may refer to a plus or minus a certain percentage (e.g., 1%, 5%, 10% or more) of the indicated value. Numerical values without the use of relative terms should also be disclosed as specific values with tolerances. In addition, "substantially" when expressing a relative angular positional relationship (e.g., substantially parallel, substantially perpendicular) may refer to a plus or minus a certain number of degrees (e.g., 1 degree, 5 degrees, 10 degrees or more) from the indicated angle.

[0056] Please refer to Figures 1 to 6, the existing glue feeding device includes a plunger pump 1, a lifting device 2 and a pressure plate 3. The plunger pump 1 is arranged at the lifting end of the lifting device 2. The lifting device 2 is configured to control the lifting of the plunger pump 1. The pressure plate 3 is fixed on the plunger pump 1. Under the action of the lifting device 2, the plunger pump 1 is inserted into the glue bucket 100, and the pressure plate 3 continuously presses on the glue surface. The glue is transported to the glue injection device through the feeding pipeline by the pressure of the pressure plate 3 and the reciprocating movement of the plunger pump 1. Since the viscosity of the glue in the glue bucket 100 is relatively high, glue is likely to remain at the bottom of the pressure plate 3, thus forming waste. It is necessary to regularly clean the waste on the pressure plate 3, which easily increases the workload of the staff. In addition, if there is residue during waste cleaning, it is likely to cause blockage of the pipeline when the glue feeding device supplies glue, thus further increasing the workload of the staff. Therefore, in this embodiment, by changing the connection relationship between the plunger pump 1 and the pressure plate 3, the pressure plate 3 is set as a consumable at the bottom of the plunger pump 1, thus avoiding the need for the staff to clean the pressure plate 3.

[0057] Specifically, the glue feeding equipment further includes a connecting seat 4 and a suction cup 5. The connecting seat 4 is arranged on the plunger pump 1 and is located above the pressure plate 3; the suction cup 5 is arranged at the bottom of the connecting seat 4 to be able to suck the pressure plate 3 when the pressure plate 3 applies pressure to the glue surface. In practical applications, the lifting device 2 can drive the connecting seat 4 to move downward. During the movement, the suction cup 5 can be sucked to the pressure plate 3. When the glue in the glue bucket 100 is completely extracted, the lifting device 2 rises, and the pressure plate 3 separates from the suction cup 5 under the action of the residual glue in the bucket, so that the pressure plate 3 remains in the glue bucket 100 as a consumable, so as to avoid cleaning the glue remaining on the pressure plate 3, thereby reducing the workload of the staff.

[0058] Since the viscosity of the glue in the glue bucket 100 is relatively high, the surface will be uneven. During the downward pressing process of the pressure plate 3, some gas will be sealed between the pressure plate 3 and the glue surface. If the gas is transported to the glue injection equipment together with the glue, it will cause the phenomenon of broken glue in the dispensing trace of the glue injection equipment. Therefore, this part of the gas needs to be extracted.

[0059] Specifically, an exhaust port is arranged on the connecting seat 4. The suction cup 5 is arranged at the exhaust port, and the exhaust port is communicated with the suction cup 5. An exhaust hole is arranged on the pressure plate 3, and the exhaust hole is arranged opposite to the suction cup 5; the glue feeding equipment further includes an air extraction mechanism, and the air extraction end of the air extraction mechanism is communicated with the exhaust port to extract the gas between the pressure plate 3 and the glue. In practical applications, under the action of the air extraction mechanism, the gas between the pressure plate 3 and the glue will enter the inside of the suction cup 5 through the exhaust hole and then be discharged through the exhaust port. It should be noted that the air extraction mechanism is preferably an air extraction component in the prior art and will not be elaborated here.

[0060] To prevent the glue from being discharged through the exhaust port during the air extraction process, in this embodiment, before the air extraction mechanism extracts air, a sealed state is established between the pressure plate 3 and the upper surface of the glue, so that the pressure plate 3 can be subjected to the resistance brought by the air pressure during the downward pressing process, thereby preventing the pressure plate 3 from contacting the glue and further preventing the glue from being discharged through the exhaust port.

[0061] Specifically, the glue feeding device further includes a sealing component 6, which is arranged at the exhaust port and is configured to block or open the exhaust hole. In practical applications, during the downward movement of the pressure plate 3, the sealing component 6 closes the exhaust hole, making the space between the pressure plate 3 and the upper surface of the glue in a sealed state. During the air extraction process, the sealing component 6 opens the exhaust hole.

[0062] The sealing component 6 includes an air connector 61, a blowing member, a guide rod 62 and a tension spring 63. The air connector 61 is arranged at the exhaust port. An air flow passage is provided inside the air connector 61, and an air extraction port and an air inlet are provided on the air connector 61; the blowing member is communicated with the air inlet and is configured to convey gas to the air inlet; the guide rod 62 is slidably arranged inside the air flow passage, and the guide rod 62 divides the air flow passage into an air extraction chamber and an air inlet chamber. The air inlet is communicated with the air inlet chamber, and the air extraction port is communicated with the air extraction chamber; the guide rod 62 can be blocked when the blowing member conveys gas to the air inlet; the tension spring 63 is arranged in the air inlet chamber, and both ends of the tension spring 63 are respectively connected to the guide rod 62 and the inner wall of the exhaust chamber to pull the guide rod 62 to open the exhaust hole when the blowing member stops conveying gas to the air inlet. It can be understood that during the downward movement of the pressure plate 3, the blowing member conveys air to the air inlet, and the air pressure in the air inlet chamber increases, so as to push the guide rod 62 to move downward to block the exhaust port. When the glue feeding device conveys glue to the glue injection device, the blowing member stops blowing, and under the action of the tension spring 63, the guide rod 62 can be pulled away from the exhaust hole, and the air extraction mechanism starts to extract the gas between the pressure plate 3 and the glue.

[0063] In this embodiment, the pressure plate 3 includes a base 31 and a baffle 32. The baffle 32 is arranged along the circumferential direction of the top of the base 31, and the outer peripheral wall of the connecting seat 4 is attached to the inner wall of the baffle 32. In this way, on the one hand, the pressure plate 3 can be more evenly subjected to the downward pressure of the connecting seat 4 during the downward pressing process, thereby preventing the position of the pressure plate 3 from shifting during the downward pressing process.

[0064] Furthermore, the baffle 32 is arranged in a wide-mouth shape. In this way, on the one hand, the sealing performance between the pressure plate 3 and the glue can be increased, and on the other hand, the friction force between the pressure plate 3 and the glue bucket 100 during the upward movement of the connecting seat 4 can be increased, so as to facilitate the separation of the suction cup 5 from the pressure plate 3.

[0065] In particular, the pressure plate 3 is made of plastic. Since plastic has excellent corrosion resistance and low cost, it can be directly replaced when the pressure plate 3 is stained, so as to reduce the cleaning time of the pressure plate 3. In addition, since plastic has good elasticity, the size of the pressure plate 3 can be slightly larger than that of the glue bucket 100, so that the pressure plate 3 can be further improved during the downward pressing process to ensure the tightness of the fit between the pressure plate 3 and the inner wall of the glue bucket 100, and then the tightness of the seal between the pressure plate 3 and the glue can be ensured. In addition, during the lifting process of the plunger pump 1, due to the large tightness of the fit between the pressure plate 3 and the inner wall of the glue bucket 100, it is convenient for the suction cup 5 to separate from the pressure plate 3.

[0066] When replacing the glue bucket 100, since the glue bucket 100 filled with glue is relatively heavy as a whole, it is not convenient for the staff to place it at the preset working position. Therefore, in this embodiment, the glue feeding device further includes a support seat 7, a draw-out plate 8 and a positioning portion. The lifting device 2 is arranged on the support seat 7; the draw-out plate 8 is slidably arranged on the support seat 7, and the draw-out plate 8 is configured to carry the glue bucket 100. The positioning portion is arranged on the top of the draw-out plate 8 and is configured to position the glue bucket 100. The positioning portion is preferably a positioning block or a positioning groove, which can be an existing positioning structure. In practical applications, the draw-out plate 8 is pulled out, and the pulling-out direction is as Figure 5 shown by the arrow direction in the figure. Subsequently, the emptied glue bucket 100 is removed, and the glue bucket 100 filled with glue is placed on the draw-out plate 8. The draw-out plate 8 is reset, and the reset direction is as Figure 6 shown by the arrow direction in the figure, and it is moved to the preset working position. Among them, the preset working position refers to the position where the glue bucket 100 is oppositely arranged with the plunger pump 1.

[0067] Furthermore, the glue feeding device further includes a proximity switch. The proximity switch is arranged on the support seat 7 and is at the end of the sliding of the draw-out plate 8 during reset. The draw-out plate 8 approaches the proximity switch during reset. When the draw-out plate 8 moves to the preset working position, the proximity switch gives an alarm, and then the draw-out plate 8 stops conveying. It is arranged in this way to improve the conveying accuracy of the draw-out plate 8.

[0068] In this embodiment, the lifting device 2 includes a mounting plate 21 and a plurality of hydraulic cylinders 22. The plunger pump 1 is arranged on the mounting plate 21, and the mounting plate 21 is slidably arranged on the support seat 7; the plurality of hydraulic cylinders 22 are evenly distributed on the support seat 7, and the piston rod ends of the plurality of hydraulic rods are connected to the mounting plate 21. The number of the hydraulic cylinders 22 is preferably four. In some other feasible embodiments, the lifting device 2 can also be other existing lifting structures, which will not be elaborated here.

[0069] Obviously, the above embodiments of the present utility model are merely examples for clearly illustrating the present utility model, rather than limitations on the implementation manners of the present utility model. For those of ordinary skill in the art, various obvious changes, re-adjustments and substitutions can be made without departing from the protection scope of the present utility model. It is not necessary and impossible to enumerate all the implementation manners here. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the claims of the present utility model.
