[0002] A dispensing machine is an automated machine that controls fluids and dispenses and applies them to the surface or interior of products. It can effectively improve the efficiency and effect of dispensing processes.

[0003] When a traditional glue dispensing machine dispenses glue on a through hole on a sleeve workpiece, it passes an internal support clamp through the internal cavity of the sleeve workpiece to fix the sleeve workpiece, thereby facilitating the injection of glue into the through hole on the sleeve workpiece. However, when a traditional glue dispensing machine injects glue into the through hole of the sleeve workpiece, since there is a gap between the inner wall of the cavity where the through hole of the sleeve workpiece is opened and the internal support clamp, and the glue has castability during injection, part of the injected glue will flow from the gap to the inner wall of the cavity of the sleeve workpiece, resulting in insufficient glue retention in the through hole and glue adhering to the inner wall of the cavity of the sleeve workpiece, which seriously affects the processing effect of the glue dispensing process.

[0028] like Figure 1 As shown, the dispensing device 10 of one embodiment includes a base 100, an internal support clamping mechanism 200 and an injection mechanism 300. Figure 2 and Figure 3 As shown, the internal support clamping mechanism 200 includes an internal support column 210, an ejector 220, an ejector drive 230 and a soft rubber covering sheet 240. The internal support column 210 is connected to the base 100. The internal support column 210 is used to penetrate the inner cavity of the sleeve workpiece. The internal support column 210 is provided with a receiving cavity 211 and a communicating hole 212 that are interconnected. The soft rubber covering sheet 240 covers the communicating hole 212. The ejector 220 is respectively arranged in the receiving cavity 211 and the communicating hole 212. The ejector 220 is connected to the power output end of the ejector drive 230. The ejector drive 230 is used to drive the ejector 220 to abut against the soft rubber covering sheet 240, so that the soft rubber covering sheet 240 is deformed and abuts against the cavity wall of the sleeve workpiece. The injection mechanism 300 includes an injection drive 310 and an injection part 320. The injection drive 310 is installed on the base 100. The power output end of the injection drive 310 is connected to the injection part 320. The injection drive 310 is used to drive the injection part 320 to move closer to or away from the dispensing hole of the sleeve workpiece.

[0029] In this embodiment, the dispensing device 10 includes a base 100, an internal support clamping mechanism 200 and an injection mechanism 300. The base 100 is the base of the dispensing device 10, which is used to fix the internal support clamping mechanism 200 and the injection mechanism 300. The internal support clamping mechanism 200 is used to clamp and fix the sleeve workpiece so that the injection mechanism 300 can inject glue into the sleeve workpiece. The injection mechanism 300 is used to inject glue into the through hole of the sleeve workpiece. Specifically, the injection mechanism 300 includes an injection drive 310 and an injection part 320. The power output end of the injection drive 310 is connected to the injection part 320. After the sleeve workpiece is fixed by the internal support clamping mechanism 200, the injection drive 310 can drive the injection part 320 to approach the sleeve workpiece. When the glue outlet of the injection part 320 reaches the through hole of the sleeve workpiece, the injection drive 310 will stop moving, and at the same time, the injection part 320 will inject glue into the through hole of the sleeve workpiece, thereby completing the dispensing process of the through hole of the sleeve workpiece. The internal support clamping mechanism 200 includes an internal support column 210, which is connected to the base 100. When fixing the sleeve workpiece, the sleeve workpiece is placed on the internal support column 210, and the sleeve workpiece is rotated and adjusted so that the through hole of the sleeve workpiece faces the injection part 320. In this way, the internal support column 210 supports the inner wall of the cavity of the sleeve workpiece, so that the sleeve workpiece is fixed on the internal support column 210. The axial direction of the internal support column 210 is usually placed horizontally, which helps to increase the support area of ​​the internal support column 210 on the inner wall of the sleeve workpiece.

[0030] Furthermore, the internal support clamping mechanism 200 further includes an ejector 220, an ejector drive 230, and a soft rubber covering sheet 240. The internal support column 210 is provided with a receiving cavity 211 and a communicating hole 212 that are interconnected. The soft rubber covering sheet 240 is covered with the communicating hole 212. The soft rubber covering sheet 240 is made of plastic material and has good deformation ability. The ejector 220 is respectively arranged at the receiving cavity 211 and the communicating hole 212. The ejector 220 can be driven by the ejector drive 230 to eject outward from the communicating hole 212 of the internal support column 210 to punch the soft rubber covering sheet 240 covering the communicating hole. 0. Since the soft rubber covering sheet 240 has good deformation ability, it will be deformed under the impact of the ejection part 220. When the sleeve workpiece is sleeved on the inner support column 210, the soft rubber covering sheet 240 deformed in the direction away from the connecting hole 212 will abut against the cavity wall of the sleeve workpiece, so that the cavity wall of the through hole opened on the sleeve workpiece is tightly fitted with the inner support column 210, and then the inner support column 210 can isolate the through hole and the internal cavity of the sleeve workpiece from each other. Therefore, when dispensing glue on the through hole of the sleeve workpiece, it can prevent the glue in the through hole from flowing to the inner wall of the sleeve workpiece, thereby improving the processing quality of the dispensing process.

[0031] like Figure 2 and Figure 3As shown, in one embodiment, the ejection member 220 includes a ejection block 221, and the ejection driving member 230 includes an air pipe 231 and an air pump. The ejection block 221 is movably disposed in the connecting hole 212, and the two ends of the air pipe 231 are respectively connected to the air outlet end of the air pump and the accommodating chamber 211. In this embodiment, the ejection member 220 includes a ejection block 221, which is movably arranged in the connecting hole 212. The ejection driving member 230 includes an air pipe 231 and an air pump. The two ends of the air pipe 231 are respectively connected to the air outlet end of the air pump and the accommodating chamber 211. The air outlet end of the air pump can output gas, and the air cylinder output by the air pump is transmitted to the accommodating chamber 211 through the air pipe 231, so that the air pressure in the accommodating chamber 211 increases. The air pressure will act on the ejection block 221, so that the ejection block 221 is ejected toward the soft rubber covering sheet 240, and finally the soft rubber covering sheet 240 is deformed and abuts against the cavity wall of the sleeve workpiece.

[0032] When the airtightness between the top block 221 and the communicating hole 212 is poor, gas will leak out from the gap between the top block 221 and the communicating hole 212, and insufficient air pressure will be generated to eject the top block 221. Figure 2 and Figure 3 As shown, in one embodiment, the ejector 220 further includes an airbag 222, which is disposed in the accommodating cavity 211. The air inlet of the airbag 222 is in communication with the air tube 231, and the side of the top block 221 away from the soft rubber cover 240 abuts against the airbag 222. In this embodiment, the ejector 220 further includes an airbag 222, which is disposed in the accommodating cavity 211 and abuts against the side of the top block 221 away from the soft rubber cover 240. The air inlet of the airbag 222 is in communication with the air tube 231. The gas output by the air pump will inflate the airbag 222. The expansion of the airbag 222 can push the top block 221 toward the soft rubber cover 240. The ejection of the top block 221 by the airbag 222 can reduce the airtightness requirement between the top block 221 and the communicating hole 212, ensuring that the top block 221 can be smoothly ejected.

[0033] like Figure 2 and Figure 3As shown, in one embodiment, the inner support column 210 is provided with a groove 213, which is connected to the communication hole 212. The soft rubber covering sheet 240 is disposed in the groove 213 so that the surface of the soft rubber covering sheet 240 away from the ejector 220 is flush with the outer surface of the inner support column 210. In this embodiment, the soft rubber covering sheet 240 is disposed in the groove 213 provided on the surface of the inner support column 210, and the surface of the soft rubber covering sheet 240 is flush with the surface of the inner support column 210. In this way, when the soft rubber covering sheet 240 is in a normal state, the soft rubber covering sheet 240 does not protrude from the surface of the inner support column 210, making it easier to insert the sleeve workpiece onto the inner support column 210.

[0034] like Figure 1 As shown, in one embodiment, the dispensing device 10 further includes a light-curing mechanism 400, which includes a lamp holder 410 and a curing lamp. The lamp holder 410 is connected to the base 100, and the curing lamp is connected to the lamp holder 410. In this embodiment, the dispensing device 10 further includes a light-curing mechanism 400, which includes a lamp holder 410 mounted on the base 100 and a curing lamp connected to the lamp holder 410. After the injection component 320 injects UV glue into the through hole of the sleeve workpiece, the glue can be immediately cured by irradiating the glue with the curing lamp, thereby preventing glue from flowing and helping to improve the processing efficiency of the dispensing process.

[0035] like Figure 1 As shown, in one embodiment, the internal support clamping mechanism 200 further includes a sliding drive 250, which is mounted on the base 100. The internal support column 210 is connected to the sliding drive 250. The sliding drive 250 is used to drive the internal support column 210 toward or away from the curing light. In this embodiment, the internal support clamping mechanism 200 further includes a sliding drive 250 mounted on the base 100. The sliding drive 250 is connected to the internal support column 210. The sliding drive 250 can drive the internal support column 210 toward or away from the curing light. After the injection component 320 injects UV water into the through hole of the sleeve workpiece, the sliding drive 250 drives the internal support column 210 toward the curing light, which can quickly move the sleeve workpiece to the light curing mechanism 400 for glue curing, thereby preventing glue from flowing out and helping to improve the processing efficiency of the dispensing process.

[0036] Since the inner support column 210 serves to isolate the through hole and the internal cavity of the sleeve workpiece, the glue injected by the injection part 320 will fall on the surface of the inner support column 210. After the glue solidifies, it is easy to cause the glue to adhere to the inner support column 210, making it difficult to extract the sleeve workpiece from the inner support column 210, or even damaging the glue after extraction. Figure 3 As shown, in one embodiment, the soft adhesive cover sheet 240 is covered on a side of the inner support column 210 adjacent to the injection piece 320 , and a side of the soft adhesive cover sheet 240 facing away from the inner support column 210 is provided with an anti-sticking layer. In this embodiment, the soft rubber covering sheet 240 is not only covered on the connecting hole 212, but also covered on the side of the inner support column 210 adjacent to the injection part 320. When the sleeve workpiece is sleeved on the inner support column 210, the inner wall of the cavity with the through hole will abut against the soft rubber covering sheet 240. When dispensing, the glue will fall on the soft rubber covering sheet 240 instead of directly falling on the surface of the inner support column 210. After the UV glue is cured on the silicone, the solidified glue can be better separated from the silicone. In this embodiment, the soft rubber covering sheet 240 is made of silicone material, or is composed of a layer of silicone sheet stacked on a plastic material, so that the side of the soft rubber covering sheet 240 abutting against the inner wall of the sleeve workpiece forms an anti-sticking layer. In this way, after the glue solidifies, the solidified glue can be prevented from sticking, and the sleeve workpiece can be pulled out more easily.

[0037] like Figure 2 and Figure 3 As shown, in one embodiment, the inner support type clamping mechanism 200 further includes a guide member connected to one end of the inner support column 210, and the cross-sectional area of ​​the guide member gradually increases along the insertion direction of the sleeve workpiece. In this embodiment, the guide member is connected to one end of the inner support column 210, and the sleeve workpiece is inserted from the end of the inner support column 210 connected to the guide member. Since the cross-sectional area of ​​the guide member gradually increases along the insertion direction of the sleeve workpiece, that is, when the inner support column 210 and the sleeve workpiece are aligned and sleeved, the cross-sectional area of ​​the end of the guide member facing the sleeve workpiece is larger than the cross-sectional area of ​​the end of the guide member away from the sleeve workpiece. In this way, when the sleeve workpiece is just inserted into the guide member, the gap between the guide member and the inner wall of the sleeve workpiece is larger, which can reduce the accuracy requirement for the alignment of the sleeve workpiece when the sleeve workpiece is inserted into the inner support column 210, and facilitate the rapid insertion of the sleeve workpiece into the inner support column 210.

[0038] like Figure 1 As shown, in one embodiment, the injection drive member 310 includes a transverse drive member and a longitudinal drive member. The transverse drive member is mounted on the base 100, and the power output end of the transverse drive member is connected to the longitudinal drive member, and the power output end of the longitudinal drive member is connected to the injection member 320. In this embodiment, the injection drive member 310 includes a transverse drive member and a longitudinal drive member. The transverse drive member can drive the injection member 320 to move horizontally, and the longitudinal drive member can drive the injection member 320 to move longitudinally, thereby improving the freedom of movement of the injection member 320 and enabling the injection member 320 to have a wider processing range.

[0039] When the ejection position of the ejector is located on the side of the inner support column adjacent to the injection part, after the ejector is ejected, the soft rubber cover sheet will bulge and deform toward the through hole of the adjacent sleeve workpiece. Since the soft rubber cover sheet is elastic, the raised portion of the soft rubber cover sheet may squeeze into the through hole of the sleeve workpiece. Since the injection amount of the injection part is fixed each time, part of the space in the through hole is occupied by the raised portion of the soft rubber cover sheet, which will cause glue to overflow from the surface of the sleeve workpiece, affecting the quality of the glue dispensing process. In addition, when the injection part is injecting glue, the injection needle of the injection part will enter the through hole of the sleeve workpiece. The injection needle may come into contact with the soft rubber cover sheet squeezed into the through hole of the sleeve workpiece, causing damage to the injection part. To this end, in one embodiment, the connecting hole is opened on the side of the inner support column facing away from the injection part. When the connecting hole is opened on the side of the inner support column facing away from the injection part, the ejector will cause the soft rubber covering sheet located on the side of the inner support column facing away from the injection part to be deformed after the ejector is ejected, so that the soft rubber covering sheet at this location protrudes in the direction away from the injection part, thereby causing the soft rubber covering sheet to abut against the inner cavity wall of the sleeve workpiece, and the part of the soft rubber covering sheet located on the side of the inner support column adjacent to the injection part will remain flat and abut against the inner cavity wall of the sleeve workpiece where the through hole is opened. In this way, it can not only prevent glue from overflowing onto the inner wall of the sleeve workpiece, but also prevent the soft rubber covering sheet from squeezing into the through hole of the sleeve workpiece, thereby preventing glue from overflowing onto the surface of the sleeve workpiece during glue injection, and preventing the injection needle of the injection part from being damaged during glue injection, which helps to improve the processing quality of the dispensing process and extend the service life of the injection part.

[0040] After the glue on the sleeve workpiece solidifies, the sleeve workpiece needs to be pulled out from the inner support column to collect the sleeve workpiece. The traditional method of taking out the material of the dispensing device is to manually pull out the sleeve workpiece, which is not only inefficient, but also the manual operation will increase the production cost. At the same time, when manually pulling out the sleeve workpiece, due to the instability of manual operation, the force direction of the manual pulling out of the sleeve workpiece cannot be completely parallel to the axial direction of the inner support column. In this way, the inner wall of the sleeve workpiece will exert pressure on the surface of the inner support column, causing the fixed end of the inner support column to bear a large load, which can easily cause the fixed end of the inner support column to deform or even be damaged. To this end, in one embodiment, the dispensing device also includes a stripping mechanism, the stripping mechanism includes a stripping part and a stripping drive part, the stripping drive part is connected to the power output end of the sliding drive part, the power output end of the stripping drive part is connected to the stripping part, the stripping part is located on the outer side surface of the end of the inner support column, and the stripping drive part is used to drive the stripping part to move along the axial direction of the inner support column. In this embodiment, after the glue in the through hole of the sleeve workpiece is cured by the curing lamp, the stripping drive will drive the stripping part to move, so that the stripping part moves from the outer surface of one end of the inner support column to the other end of the inner support column. Since the sleeve workpiece is also sleeved on the inner support column, the stripping part will abut against the end of the sleeve workpiece during the movement and push the sleeve workpiece to move on the inner support column. When the stripping part moves to the limit, the sleeve workpiece will be pushed away from the inner support column. In this way, the finished glue-dispensing products can be collected directly without the need for manual extraction of the sleeve workpiece, making the extraction operation of the sleeve workpiece fully automated, saving labor costs and improving efficiency. At the same time, since the stripping part moves along the axial direction of the inner support column to push the sleeve workpiece away from the inner support column, the ejection direction of the sleeve workpiece is consistent with the axial direction of the inner support column, which can prevent the sleeve workpiece from damaging the inner support column when it is separated from the inner support column, thereby improving the service life of the glue-dispensing device.

[0041] After the glue on the sleeve workpiece solidifies, the ejector will reset, and the soft rubber covering sheet will reset after losing the abutment effect of the ejector, so that the sleeve workpiece can be inserted into the inner support column again. However, after the soft rubber covering sheet has been used for a long time, the elasticity of the soft rubber covering sheet will decrease, making it impossible for the soft rubber covering sheet to be completely reset, that is, after the sleeve workpiece is pulled out, the soft rubber covering sheet still protrudes from the surface of the inner support column, so that the sleeve workpiece is blocked by the raised portion of the soft rubber covering sheet when it is inserted into the inner support column, making it difficult for the sleeve workpiece to be inserted into the inner support column. To this end, in one embodiment, the stripping piece includes a stripping cylinder, which is sleeved on the inner support column, and the inner wall of the stripping cylinder is adapted to the outer side surface of the inner support column, and the stripping cylinder is connected to the power output end of the stripping drive member. In this embodiment, the stripping drive member drives the stripping cylinder to move to push the sleeve workpiece away from the inner support column. Since the stripping cylinder is sleeved on the inner support column, and the inner wall of the stripping cylinder is adapted to the outer side surface of the inner support column, during the movement of the stripping cylinder, the inner wall of the stripping cylinder will abut against the raised soft rubber covering sheet, so that the soft rubber covering sheet is subjected to pressure toward the axis of the inner support column. The soft rubber covering sheet will deform under the pressure of the inner wall of the stripping cylinder, so that the soft rubber covering sheet returns to a state that is tightly attached to the surface of the inner support column. In this way, when the sleeve workpiece is inserted onto the inner support column again, the situation where the soft rubber covering sheet hinders the insertion of the sleeve workpiece can be avoided, so that the insertion of the sleeve workpiece is smoother.

[0042] In the process of ejecting the sleeve workpiece and pressing down the raised soft rubber covering sheet, due to the sliding friction between the stripping cylinder and the soft rubber covering sheet, the friction between the stripping cylinder and the soft rubber covering sheet is relatively large, which may cause the soft rubber covering sheet to hinder the movement of the stripping cylinder, making it impossible to eject the sleeve workpiece normally and the soft rubber covering sheet unable to be pressed down and reset. To this end, in one embodiment, the stripping part also includes a roller, which is connected to the inner wall of the stripping cylinder, and the roller abuts against the side of the inner support column facing away from the injection part. During the process of ejecting the sleeve workpiece by the stripping cylinder, the roller will move with the stripping cylinder and roll the outer side surface of the inner support column. Since the ejection position of the ejector is located on the side of the inner support column facing away from the injection part, during the movement of the stripping cylinder, the roller will abut against the soft rubber covering sheet provided on the side of the inner support column facing away from the injection part to roll the soft rubber covering sheet at this location, so that the soft rubber covering sheet at this location is restored to a state of being in contact with the surface of the inner support column. Since there is rolling friction between the roller and the soft rubber covering sheet, the friction force is small, which can avoid the situation where the stripping cylinder is hindered by the raised soft rubber covering sheet during movement, making the ejection process of the stripping cylinder smoother. At the same time, pressing the soft rubber covering sheet down by the roller rolling method can reduce the extrusion of the soft rubber covering sheet along the axial direction of the inner support column, thereby reducing the damage of the stripping part to the soft rubber covering sheet.

[0043] During the curing process of the glue, there may be situations where the glue is not completely cured or the glue is adhered to the soft glue covering sheet, resulting in residual glue on the soft glue covering sheet. The presence of residual glue will cause the glue block formed by the subsequent glue dispensing to be incomplete, resulting in a decrease in the quality of the subsequent glue dispensing process. To this end, in one embodiment, the stripping part also includes a glue removal gasket, which is attached to the inner wall of the stripping cylinder, and the glue removal gasket abuts against the side of the inner support column adjacent to the injection part. In this embodiment, during the process of the stripping cylinder pushing the sleeve workpiece away from the inner support column, the glue removal gasket will move with the stripping cylinder. Since the glue removal gasket abuts against the outer side surface of the inner support column, during the movement of the stripping cylinder, the glue removal gasket will wipe the side of the inner support column adjacent to the injection part to remove the residual glue or glue on the soft glue covering sheet. In this way, the residual glue can be prevented from affecting the subsequent glue dispensing process, which helps to improve the processing quality of the next glue dispensing process. It is understandable that after the degumming gasket has been used for a long time, the degumming gasket can be torn off from the inner wall of the stripping cylinder and replaced with a new one to obtain better cleaning quality.

[0044] The degumming gasket needs to be replaced after being used for a long time. However, since the degumming gasket is located on the inner wall of the stripping cylinder, it is necessary to insert the degumming gasket into the stripping cylinder to operate the degumming gasket, which makes it difficult to replace the degumming gasket. To this end, in one embodiment, the stripping cylinder includes a first cylinder portion and a second cylinder portion, the first cylinder portion is used to cover the side of the inner support column adjacent to the injection component, and the second cylinder portion is used to cover the side of the inner support column facing away from the injection component. The degumming gasket is attached to the side of the first cylinder portion adjacent to the inner support column, and the first cylinder portion and the second cylinder portion are detachably connected. Since the first cylinder portion and the second cylinder portion are detachably connected, when the degumming gasket needs to be replaced, the stripping cylinder portion can be disassembled so that the first cylinder portion and the second cylinder portion are separated. Since the degumming gasket is attached to the side of the first cylinder portion adjacent to the inner support column, after the first cylinder portion and the second cylinder portion are separated, the degumming gasket on the first cylinder portion can be directly replaced, which helps to reduce the difficulty of replacing the degumming gasket and improve the replacement efficiency.

[0045] The present application also provides a dispensing device, including the dispensing device 10 described in any of the above embodiments. Figure 1 As shown in FIG. 1 , in one embodiment, the dispensing device 10 includes a base 100, an internal support clamping mechanism 200 and an injection mechanism 300. Figure 2 and Figure 3As shown, the internal support clamping mechanism 200 includes an internal support column 210, an ejector 220, an ejector drive 230 and a soft rubber covering sheet 240. The internal support column 210 is connected to the base 100. The internal support column 210 is used to penetrate the inner cavity of the sleeve workpiece. The internal support column 210 is provided with a receiving cavity 211 and a communicating hole 212 that are interconnected. The soft rubber covering sheet 240 covers the communicating hole 212. The ejector 220 is respectively arranged in the receiving cavity 211 and the communicating hole 212. The ejector 220 is connected to the power output end of the ejector drive 230. The ejector drive 230 is used to drive the ejector 220 to abut against the soft rubber covering sheet 240, so that the soft rubber covering sheet 240 is deformed and abuts against the cavity wall of the sleeve workpiece. The injection mechanism 300 includes an injection drive 310 and an injection part 320. The injection drive 310 is installed on the base 100. The power output end of the injection drive 310 is connected to the injection part 320. The injection drive 310 is used to drive the injection part 320 to move closer to or away from the dispensing hole of the sleeve workpiece.

[0046] In this embodiment, the dispensing device 10 includes a base 100, an internal support clamping mechanism 200 and an injection mechanism 300. The base 100 is the base of the dispensing device 10, which is used to fix the internal support clamping mechanism 200 and the injection mechanism 300. The internal support clamping mechanism 200 is used to clamp and fix the sleeve workpiece so that the injection mechanism 300 can inject glue into the sleeve workpiece. The injection mechanism 300 is used to inject glue into the through hole of the sleeve workpiece. Specifically, the injection mechanism 300 includes an injection drive 310 and an injection part 320. The power output end of the injection drive 310 is connected to the injection part 320. After the sleeve workpiece is fixed by the internal support clamping mechanism 200, the injection drive 310 can drive the injection part 320 to approach the sleeve workpiece. When the glue outlet of the injection part 320 reaches the through hole of the sleeve workpiece, the injection drive 310 will stop moving, and at the same time, the injection part 320 will inject glue into the through hole of the sleeve workpiece, thereby completing the dispensing process of the through hole of the sleeve workpiece. The internal support clamping mechanism 200 includes an internal support column 210, which is connected to the base 100. When fixing the sleeve workpiece, the sleeve workpiece is placed on the internal support column 210, and the sleeve workpiece is rotated and adjusted so that the through hole of the sleeve workpiece faces the injection part 320. In this way, the internal support column 210 supports the inner wall of the cavity of the sleeve workpiece, so that the sleeve workpiece is fixed on the internal support column 210. The axial direction of the internal support column 210 is usually placed horizontally, which helps to increase the support area of ​​the internal support column 210 on the inner wall of the sleeve workpiece.

[0047] Furthermore, the internal support clamping mechanism 200 further includes an ejector 220, an ejector drive 230, and a soft rubber covering sheet 240. The internal support column 210 is provided with a receiving cavity 211 and a communicating hole 212 that are interconnected. The soft rubber covering sheet 240 is covered with the communicating hole 212. The soft rubber covering sheet 240 is made of plastic material and has good deformation ability. The ejector 220 is respectively arranged at the receiving cavity 211 and the communicating hole 212. The ejector 220 can be driven by the ejector drive 230 to eject outward from the communicating hole 212 of the internal support column 210 to punch the soft rubber covering sheet 240 covering the communicating hole. 0. Since the soft rubber covering sheet 240 has good deformation ability, it will be deformed under the impact of the ejection part 220. When the sleeve workpiece is sleeved on the inner support column 210, the soft rubber covering sheet 240 deformed in the direction away from the connecting hole 212 will abut against the cavity wall of the sleeve workpiece, so that the cavity wall of the through hole opened on the sleeve workpiece is tightly fitted with the inner support column 210, and then the inner support column 210 can isolate the through hole and the internal cavity of the sleeve workpiece from each other. Therefore, when dispensing glue on the through hole of the sleeve workpiece, it can prevent the glue in the through hole from flowing to the inner wall of the sleeve workpiece, thereby improving the processing quality of the dispensing process.

It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the patent for this invention shall be determined by the appended claims.
