Description

Technical Field

[0001] The utility model relates to the technical field of watch production, in particular to a glue dispensing machine used for automatically and quantitatively adding waterproof oil to a waterproof ring. Background Art

[0002] The basic process of waterproofing a watch is to add a rubber gasket between the watch mirror and the watch case, and between the watch case and the watch bottom to act as a seal. Considering the special nature of the rubber material, the waterproofing of a round watch case is easier to handle than that of a special-shaped watch case (such as a barrel shape). It is worth mentioning that the use of rubber gaskets for waterproofing is not only used in watches, but is also widely used in the fields of electronics and digital technology. The existing watch waterproof rings need to be manually filled with waterproof oil, and a refueling device in the form of a dispensing machine is used to accurately control the single refueling. However, the area of ​​the waterproof ring that contacts the waterproof oil is limited, and the oil that is not contaminated can only remain in the refueling device, causing waste. Therefore, a dispensing machine for automatically and quantitatively adding waterproof oil to the waterproof ring is urgently needed. Utility Model Content

[0003] 1. Technical Problems to be Solved by the Utility Model

[0004] In view of the problems existing in the prior art, the purpose of the utility model is to provide a dispensing machine for automatically and quantitatively adding waterproof oil to waterproof rings, which has the advantage of being able to recover residual oil, thus solving the problem that residual oil in previous refueling devices cannot be recovered and cleaned.

[0005] 2. Technical solution

[0006] To solve the above problems, the utility model adopts the following technical solutions.

[0007] A dispensing machine for automatically and quantitatively adding waterproof oil to a waterproof ring, the structure of which includes a mounting column, a fixing part, a locking part, an oil cylinder fixed to the mounting column by the locking part, a base plate arranged just below the oil cylinder and connected to the mounting column, the base plate including a U-shaped plate fixed on the top and a placement groove coaxial with the oil outlet of the oil cylinder on the U-shaped plate for placing the waterproof ring, a reflux mechanism fixed below the placement groove and an air pump arranged on one side, the reflux mechanism and the air pump being connected by an air pipe.

[0008] As an optimization, the reflux mechanism includes a reflux channel opened in the middle, a suction channel arranged at the upper end of the reflux channel to suck back the oil in the placement tank, and a guide block directly connected to the top of the reflux mechanism. The waterproof ring can be directly placed on the guide block. The suction channel passes through the air pipe connected to the bottom of the reflux mechanism, and air is pumped after the air pump is turned on. Since the suction channel is connected to the reflux channel, a negative pressure environment is formed in the two channels. Combined with the conical structure of the guide block arranged above the reflux mechanism, after the oil wets the waterproof ring, it flows from the guide block to the suction port of the suction channel, and the reflux mechanism is sunken inward toward the center, thereby increasing the coverage area of ​​the remaining oil and the suction port. Because the viscosity of the oil makes it difficult to flow into the suction channel, the air pump is turned on to suck away the oil above the reflux mechanism.

[0009] As an optimization, the oil cylinder includes a cylinder cover, an oil pushing air port and an oil return port respectively arranged in the middle and on the side of the cylinder cover, and an oil pushing block sliding in the oil cylinder. The oil is placed under the oil pushing block. After the control mechanism operates the oil pushing block to ventilate the oil pushing air pipe, there is a gap above the oil pushing block, and the gas pushes the oil pushing block to push the oil from the bottom into the placement groove.

[0010] As an optimization, the oil pusher block includes an oil inlet port opened in the middle.

[0011] As an optimization, the oil return pipe of the air pump is connected to the oil return port, the oil pushing air port is connected to the oil pushing air pipe arranged on the oil cylinder and the other end of the oil pushing air pipe is connected to the control mechanism to realize the control of the oil pushing amount. After the air pump is turned on, the return port sucks the residual oil into the oil through the oil return pipe in the above-mentioned manner and guides the oil to the upper end of the oil cylinder. The oil will then fall onto the oil pushing block until it reaches the oil inlet, so that the reflux oil can flow back into the oil below.

[0012] As an optimization, the oil inlet is larger at the top and smaller at the bottom.

[0013] As an optimization, the guide block adopts a conical structure and the upper end of the reflux mechanism is a structure sunken toward the center.

[0014] As an optimization, a pneumatic control valve is set inside the control mechanism, and electronic technology is used to control the air output, thereby accurately regulating the air output of the oil pushing air pipe, thereby controlling the oil output of a single oil cylinder.

[0015] 3. Beneficial effects

[0016] Compared with the prior art, the utility model has the following advantages: the utility model is a dispensing machine for automatically and quantitatively adding waterproof oil to a waterproof ring. Through a reflux mechanism arranged in a placement groove just below the oil outlet cylinder, after the oil wets the waterproof ring, the guide block and the structural arrangement of the upper surface of the reflux mechanism are combined, so that after the air pump is turned on, the oil flows out from the suction channel and the reflux channel through the negative pressure and falls back into the oil cylinder through the return oil pipe. In summary, the residual oil can be conveniently recovered through the reflux mechanism, thereby improving the utilization rate of the waterproof oil and reducing waste.

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Example

[0025] See also Figure 1-5 A dispensing machine for automatically and quantitatively adding waterproof oil to a waterproof ring, the structure of which includes a mounting column 9, a fixing member 7, a locking member 5, an oil cylinder 3 fixed on the mounting column 9 by the locking member 5, a bottom plate 10 arranged directly below the oil cylinder 3 and connected to the mounting column 9, the bottom plate 10 includes a U-shaped plate 70 fixed on the top and a placement groove 77 for placing the waterproof ring coaxially with the oil outlet of the oil cylinder 3 is opened on the U-shaped plate 70, a reflux mechanism 79 fixed below the placement groove 77 and an air pump 73 arranged on one side, and the reflux mechanism 79 is connected to the air pump 73 by an air pipe.

[0026] In this embodiment, the reflux mechanism 79 includes a reflux channel 301 opened in the middle, a suction channel 303 arranged at the upper end of the reflux channel 301 to suck back the oil in the placement groove 77, and a guide block 307 directly connected to the top of the reflux mechanism 79. The waterproof ring can be directly placed on the guide block 307.

[0027] The above-mentioned suction channel 303 is connected to the air pipe below the reflux mechanism 79, and air is pumped after the air pump 73 is turned on. Since the suction channel 303 is connected to the reflux channel 301, a negative pressure environment is formed in the two channels. In conjunction with the conical structure of the guide block 307 arranged above the reflux mechanism 79, after the oil wets the waterproof ring, it flows from the guide block 307 to the suction port of the suction channel 303, and the reflux mechanism 79 is sunken inward toward the center, thereby allowing the remaining oil to increase the coverage area of ​​the suction port. Because the viscosity of the oil makes it difficult to flow into the suction channel 303, the air pump 73 is turned on to suck away the oil above the reflux mechanism 79.

[0028] In this embodiment, the oil cylinder 3 includes a cylinder cover 35, an oil push air port 33 and an oil return port 30 respectively arranged in the middle and on the side of the cylinder cover 35, and an oil push block 37 sliding in the oil cylinder 3, and the oil is placed below the oil push block 37.

[0029] After the control mechanism 15 is operated to ventilate the oil pushing gas pipe 13 , a gap exists above the oil pushing block 37 , and the gas pushes the oil pushing block 37 to push the oil from below and drop it into the placement groove 77 .

[0030] In this embodiment, the oil pushing block 37 includes an oil inlet 523 opened in the middle.

[0031] In this embodiment, the oil return pipe 1 of the air pump 73 is connected to the oil return port 30, the oil pushing air port 33 is connected to the oil pushing air pipe 13 set on the oil cylinder 3, and the other end of the oil pushing air pipe 13 is connected to the control mechanism 15 to realize the control of the oil pushing amount.

[0032] After the air pump 73 is turned on, the above-mentioned reflux port 30 sucks the residual oil into the oil return pipe 1 in the above-mentioned manner and guides the oil to the upper end of the oil cylinder 3. The oil will then fall onto the oil push block 37 until it reaches the oil inlet 523, so that the refluxed oil can flow back into the oil below.

[0033] In this embodiment, the oil inlet 523 is in a structure of being larger at the top and smaller at the bottom.

[0034] The above-mentioned structure with a larger upper part and a smaller lower part is set up, because the lower part is in contact with the oil, and the viscosity of the oil is used to make the oil block the oil inlet 523, so that when the push block 37 is pushed by the gas above, the movement of the push block 37 will not be affected by the setting of the oil inlet 523.

[0035] In this embodiment, the guide block 307 adopts a conical structure and the upper end of the return mechanism 79 is a structure that is sunken toward the center.

[0036] In this embodiment, a pneumatic control valve is provided inside the control mechanism 15, and the air output is controlled by electronic technology, thereby accurately regulating the air output of the oil pushing air pipe 13, thereby controlling the oil output of a single oil cylinder 3.

[0037] After the waterproof ring is placed in the placement groove 77, the control mechanism 15 is turned on to ventilate the oil pushing air pipe 13, so that the air pipe 13 pushes the pushing block 37 in the oil cylinder 3 downward to push the oil into the placement groove 77 to infect the waterproof ring.

[0038] Subsequently, the air pump 73 is turned on to pump air. Since the suction channel 303 is connected to the return channel 301, a negative pressure environment is formed in the two channels. In conjunction with the conical structure of the guide block 307 arranged above the reflux mechanism 79, after the oil wets the waterproof ring, it flows from the guide block 307 to the suction port of the suction channel 303, and the reflux mechanism 79 is sunken inward toward the center, thereby allowing the remaining oil to increase the coverage area of ​​the suction port. Because the viscosity of the oil makes it difficult to flow into the suction channel 303, the air pump 73 is turned on to suck away the oil above the reflux mechanism 79, so that the refluxed oil is guided from the return oil pipe 1 on the air pump 73 into the oil cylinder 3, falls onto the push block 37, and is reintegrated into the oil through the set oil inlet 523.
