Description

Technical Field

[0001] This utility model relates to the field of dispensing machine technology, and in particular to an automatic glue changing device and a dispensing machine for a swing-type dispensing machine. Background Technology

[0002] A dispensing machine generally includes a dispensing valve and a glue cartridge for supplying glue to the valve. When the glue in the cartridge is used up, a new cartridge needs to be replaced. Therefore, dispensing machines are generally equipped with a glue changing mechanism. However, as workpiece structures become more complex and the dispensing positions on the workpieces become more specialized, the lifting and lowering motion of the dispensing valve can no longer meet the current dispensing requirements. It needs to swing within a certain range to achieve tilted dispensing. If the glue changing mechanism rotates synchronously with the dispensing valve, the rotation radius is large, requiring a large space. Furthermore, the synchronous rotation of both results in a large inertia, which reduces the stability of the overall structure. In addition, the existing glue changing mechanism is relatively complex. Utility Model Content

[0003] The technical problem to be solved by this utility model is: in order to solve the problem that the glue changing mechanism and the glue valve of the existing glue dispensing machine rotate synchronously, the rotation radius is large, which requires a lot of space, and the synchronous rotation of the two leads to a large inertia, which will reduce the stability of the overall structure. In addition, the glue changing mechanism is relatively complex. Therefore, an automatic glue changing device and a glue dispensing machine for a swing type glue dispensing machine are provided.

[0004] To solve the above-mentioned technical problems, this utility model adopts the following technical solution: an automatic glue changing device for a swing-type dispensing machine, the dispensing machine including a valve body, a glue cylinder for supplying glue to the valve body, a sealing plug covering the glue cylinder to seal the glue cylinder, a swing mechanism for driving the valve body and the glue cylinder to swing, and a base plate for mounting the swing mechanism, the automatic glue changing device being used to replace the glue cylinder in the rotary reset state, the automatic glue changing device including:

[0005] A first clamping mechanism is used to clamp or release the rubber tube;

[0006] The second clamping mechanism is used to clamp or release the sealing plug;

[0007] A lifting mechanism, which is mounted on the base plate and is used to move the sealing plug held by the second clamping mechanism closer to or away from the rubber tube to seal or open the rubber tube.

[0008] A locking mechanism is provided to lock the sealing plug to the rubber tube and automatically unlock it as the lifting mechanism moves the sealing plug away from the rubber tube.

[0009] Furthermore, the sealing plug protrudes radially to form a pressure-receiving portion, and the locking mechanism includes a pressure block sleeved on the outside of the sealing plug and pressed above the pressure-receiving portion, and the pressure block is magnetically fixed to the first clamping mechanism.

[0010] Furthermore, one of the first clamping mechanism and the pressure block has a positioning protrusion, and the other has a positioning groove for the positioning protrusion to be inserted into.

[0011] Furthermore, the top of the rubber tube has a flange protruding radially, and the first clamping mechanism includes two first jaws that can move closer to or further away from each other. The first jaws clamp the rubber tube and abut against the flange.

[0012] Furthermore, the second clamping mechanism includes two second jaws that can move closer or further apart, and the sealing plug has an upper limit portion and a lower limit portion that protrude radially, with a clamping portion for the second jaws to clamp between the upper limit portion and the lower limit portion.

[0013] Furthermore, the pressing block has a split structure, which includes two detachably connected pressing parts.

[0014] Furthermore, the output end of the swing mechanism is connected to a swing arm plate, a valve body adapter plate is connected between the swing arm plate and the valve body, and a rubber sleeve adapter plate is connected between the swing arm plate and the first clamping mechanism.

[0015] Furthermore, the swing mechanism includes a motor, a drive pulley connected to the output end of the motor, a driven pulley, and a synchronous belt wound around the drive pulley and the driven pulley, wherein the driven pulley is connected to the swing arm plate.

[0016] Furthermore, several magnets are embedded on the side of the pressure block that is close to the first clamping mechanism.

[0017] A dispensing machine includes the above-mentioned automatic glue changing device.

[0018] The beneficial effects of this utility model are as follows: This utility model fixes the automatic glue changing device so that it does not rotate with the valve body, resulting in a smaller overall rotation radius and less inertia when the valve body is tilted, making the overall structure more stable. In addition, the locking mechanism locks the new glue cartridge and the sealing plug after replacement, and the lifting mechanism automatically unlocks the glue cartridge and the sealing plug, thereby realizing the rapid replacement of the glue cartridge and improving the glue dispensing efficiency.

[0040] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention. Therefore, they only show the components relevant to the present invention. Orientations and references (e.g., up, down, left, right, etc.) are only used to aid in the description of the features in the drawings. Therefore, the following specific embodiments are not intended to be restrictive, and the scope of the claimed subject matter is defined solely by the appended claims and their equivalents.

[0041] like Figure 1 and Figure 2As shown, an automatic glue changing device for a swing-type dispensing machine includes a valve body 1, a glue cylinder 2 for supplying glue to the valve body 1, a sealing plug 3 covering the glue cylinder 2 to seal it, a swing mechanism 4 for swinging the valve body 1 and the glue cylinder 2, and a base plate 5 for mounting the swing mechanism 4. The bottom of the glue cylinder 2 is connected to the valve body 1 through a glue inlet block. During the dispensing process, the glue in the glue cylinder 2 enters the valve body 1 through the glue inlet block and is sprayed out through the dispensing head for dispensing. When the dispensing position of the workpiece is special and requires tilting, the swing mechanism 4 drives the valve body 1 and the glue cylinder 2 to rotate synchronously to face the position for dispensing.

[0042] The automatic glue changing device is used to replace the rotary reset glue cylinder 2. The automatic glue changing device includes:

[0043] The first clamping mechanism 6 is used to clamp or release the rubber tube 2;

[0044] The second clamping mechanism 7 is located above the first clamping mechanism 6 and is used to clamp or release the sealing plug 3.

[0045] The lifting mechanism 8 is mounted on the base plate 5 and is used to move the sealing plug 3 held by the second clamping mechanism 7 closer to or away from the glue cylinder 2 to seal or open the glue cylinder 2. That is, in this embodiment, both the valve body 1 and the glue cylinder 2 are connected to the output end of the swing mechanism 4 and are rotatable. The lifting mechanism 8 is fixed on the base plate 5 and does not rotate with the swing mechanism 4. Therefore, when the valve body 1 rotates, the overall rotation radius is small and the inertia is small, and the overall structure is more stable. Furthermore, if the glue cylinder 2 is replaced while it is tilted, the glue inside may leak from the top when it is tilted because the new glue cylinder 2 is not yet sealed. Therefore, the automatic glue replacement device is fixed on the base plate 5 and does not rotate synchronously with the valve body 1. This saves space, improves the stability of the entire device, and also avoids glue leakage.

[0046] And a locking mechanism 9, used to lock the sealing plug 3 to the rubber tube 2 and automatically unlock it during the process of the lifting mechanism 8 moving the sealing plug 3 away from the rubber tube 2.

[0047] During operation, the three-dimensional drive mechanism first moves the substrate 5 and the valve body 1 on it to the top of the workpiece, and takes a picture of it and positions it through the vision detection structure 13. Then, the three-dimensional drive mechanism moves the valve body 1 down to dispense glue, which is vertical. When tilting glue is required, the swing mechanism 4 drives the valve body 1 and the glue tube 2 to rotate so that the glue dispensing head is directly facing the glue dispensing position. When the glue in the glue tube 2 is used up during the tilting glue dispensing process, the swing mechanism 4 drives the valve body 1 and the glue tube 2 back to the vertical position. Then, the lifting mechanism 8 moves the sealing plug 3 up. During the upward movement, the locking mechanism 9 automatically unlocks. Then, the first clamping mechanism 6 releases the current glue tube 2. At the same time, the robot takes away the old glue tube 2 and transports the new glue tube 2 to the position of the first clamping mechanism 6. The first clamping mechanism 6 clamps the new glue tube 2. The lifting mechanism 8 moves the sealing plug 3 held by the second clamping mechanism 7 down to insert into the glue tube 2 to seal it. The locking mechanism 9 locks the glue tube 2 and the sealing plug 3 to maintain the sealed state of the glue tube 2.

[0048] In some examples, the sealing plug 3 protrudes radially to form a pressure-receiving part 301, which abuts against the opening of the rubber tube 2. The locking mechanism 9 includes a pressure block 901 sleeved on the outside of the sealing plug 3 and pressed above the pressure-receiving part 301. The pressure block 901 is magnetically fixed to the first clamping mechanism 6. When the first clamping mechanism 6 clamps the rubber tube 2, the lifting mechanism 8 drives the sealing plug 3 to move down, and the pressure block 901 sleeved on its outside moves down synchronously. During the process of the sealing plug 3 being inserted into the rubber tube 2, the pressure block 901 is magnetically fixed to the first clamping mechanism 6, that is, the pressure block 901 is relatively fixed to the rubber tube 2. The pressure block 901 applies pressure to the pressure-receiving part 301 to lock the sealing plug 3 and the rubber tube 2. When the rubber tube 2 is replaced, the lifting mechanism 8 drives the sealing plug 3 and the pressure block 901 on it to move up synchronously. The rubber tube 2 remains fixed, and the magnetically fixed pressure block 901 and the rubber tube 2 are automatically unlocked. Then the first clamping mechanism 6 releases the rubber tube 2 for replacement.

[0049] In some examples, one of the first clamping mechanism 6 and the pressure block 901 has a protruding positioning protrusion 601, and the other has a positioning groove 9011 for the positioning protrusion 601 to be inserted. In this embodiment, the positioning protrusion 601 is located on the first clamping mechanism 6, and the positioning groove 9011 is located on the pressure block 901. The head of the positioning protrusion 601 is conical, which facilitates the insertion of the positioning protrusion 601. The positioning protrusion 601 can be, but is not limited to, a pin. When the first clamping mechanism 6 clamps the new rubber tube 2, the lifting mechanism 8 drives the sealing plug 3 to move down, and at the same time, the positioning protrusion 601 inserts into the positioning groove 9011 to guide the downward movement of the sealing plug 3.

[0050] In some examples, the top of the rubber tube 2 has a flange 201 that protrudes radially. The first clamping mechanism 6 includes two first jaws that can move closer to or further away from each other. The first jaws clamp the rubber tube 2 and abut against the flange 201. The first clamping mechanism 6 can hold the rubber tube 2 while clamping it, so that the rubber tube 2 will not come out of the clamping of the first clamping mechanism 6 during the pressing of the sealing plug 3.

[0051] In some examples, the second clamping mechanism 7 includes two second jaws that can move closer or further apart. The sealing plug 3 has an upper limit portion 302 and a lower limit portion 303 that protrude radially. The upper limit portion 302 and the lower limit portion 303 are spaced apart along the axial direction of the sealing plug 3, and a clamping portion for the second jaws to clamp is formed between them. The upper limit portion 302 and the lower limit portion 303 can limit the second jaws to prevent them from slipping off during the clamping of the sealing plug 3.

[0052] In some examples, the pressure block 901 is a split structure, which includes two detachably connected pressing parts. The connection between the two parts can be, but is not limited to, fixing by bolts, and the two pressing parts are joined together to form the pressure block 901.

[0053] In some examples, the output end of the swing mechanism 4 is connected to a swing arm plate 10, a valve body adapter plate 11 is connected between the swing arm plate 10 and the valve body 1, and a rubber tube adapter plate 12 is connected between the swing arm plate 10 and the first clamping mechanism 6. The swing mechanism 4 drives the valve body 1 and the rubber tube 2 to rotate synchronously through the swing arm plate 10.

[0054] In some examples, the swing mechanism 4 includes a motor 401, a drive pulley 402 connected to the output end of the motor 401, a driven pulley 403, and a synchronous belt 404 wound around the drive pulley 402 and the driven pulley 403. The driven pulley 403 is connected to the swing arm plate 10. When the motor 401 is started, it drives the drive pulley 402 to rotate. The drive pulley 402 drives the driven pulley 403 to rotate synchronously through the synchronous belt 404. The driven pulley 403 drives the valve body 1 and the rubber cylinder 2 to rotate through the swing arm plate 10.

[0055] In some examples, a plurality of magnets 902 are embedded on the side of the pressure block 901 that is close to the first clamping mechanism 6. Both the pressure block 901 and the first clamping mechanism 6 have mounting slots for the magnets 902 to be inserted. The magnets 902 are ordinary magnets 902 or electromagnets 902.

[0056] In some examples, a dispensing machine includes the aforementioned automatic glue changing device.

[0057] Working principle:

[0058] During operation, the three-dimensional drive mechanism first moves the substrate 5 and its valve body 1 above the workpiece, and then positions it by taking a picture through the vision inspection structure 13. Next, the three-dimensional drive mechanism moves the valve body 1 downwards for dispensing, which is vertical dispensing. When tilting dispensing is required, the swing mechanism 4 rotates the valve body 1 and the glue cylinder 2 to make the dispensing head face the dispensing position. During tilting dispensing, when the glue in the glue cylinder 2 is used up, the swing mechanism 4 moves the valve body 1 and the glue cylinder 2 back to the vertical position. Then, the lifting mechanism 8 moves the sealing plug 3 upwards through the second clamping mechanism 7, and the sealing plug 3 moves the pressure block 901 mounted on it. Simultaneously, the robot moves upward, and then the first clamping mechanism 6 releases the current glue tube 2. At the same time, the robot removes the old glue tube 2 and transports the new glue tube 2 to the position of the first clamping mechanism 6. The first clamping mechanism 6 clamps the new glue tube 2. The lifting mechanism 8 drives the sealing plug 3 held by the second clamping mechanism 7 to move downward and gradually insert it into the glue tube 2. At the same time, the positioning protrusion 601 on the first gripper engages with the positioning groove 9011 on the pressure block 901 to guide the downward movement of the sealing plug 3 until the pressure block 901 and the first clamping mechanism 6 are magnetically fixed. The pressure block 901 presses down on the sealing plug 3 and locks the sealing plug 3 and the glue tube 2 to seal the glue tube 2.
