[0002] Glue dispensing machine, also known as glue coating machine, glue dripping machine, glue spraying machine, glue filling machine, etc., is a machine that specializes in controlling fluids and dripping and applying fluids to the surface or inside of products.

[0003] Window shakers require glue dispensing machines during production and processing. The surface of the window shaker is divided into two cover-like parts, and the cover-like parts are combined to confine the window shaker rod, gears and other equipment therein. After the cover-like parts are closed, there will be gaps, affecting subsequent use. Therefore, a glue dispensing machine is needed to close and seal the gap. There are some glue dispensing machines on the market, but most of them are aimed at general glue dispensing needs. For the dispensing of closed covers of specific shapes and sizes, there are problems of poor adaptability and inconvenient operation, resulting in poor dispensing accuracy. Summary of the invention

[0004] In order to improve the above problems, the present application provides a window regulator closing cover glue dispensing machine.

[0005] The present application provides a window regulator closing cover dispensing machine that adopts the following technical solution:

[0006] A glue dispensing machine for a window shaker closing cover comprises a workbench, a glue dispensing part, a glue dispensing lifting part, a glue dispensing moving part, a placement seat and a placement moving part; the glue dispensing moving part is installed on the workbench, the glue dispensing lifting part is connected to the moving end of the glue dispensing moving part; the glue dispensing part is connected to the lifting end of the glue dispensing lifting part; the placement moving part is installed on the workbench and is located below the glue dispensing moving part, and the moving path of the placement moving part forms a vertical angle with the moving path of the glue dispensing moving part; the placement seat is installed at the moving end of the placement moving part; a glue dispensing groove for placing a closing cover is provided on the placement seat.

[0007] By adopting the above technical scheme, the closed cover is stored in the dispensing groove of the placement seat, and the dispensing lifting member and the dispensing member are driven to move horizontally by the dispensing moving member. At the same time, the placement seat is driven by the placement moving member to move along the workbench toward the dispensing moving member, so that the dispensing lifting member drives the dispensing member to move in the vertical direction. According to the dispensing position required by the closed cover on the dispensing groove, the placement moving member drives the placement seat to move, and the dispensing moving member drives the dispensing member to move. The dispensing member provides dispensing synchronously, so that the dispensing position of the closed cover by the dispensing member can be flexibly adjusted, thereby ensuring the accuracy of the dispensing position.

[0008] Optionally, the dispensing component includes a glue delivery hose, a glue dispensing cylinder, a glue dispensing head and a glue dispensing cover; the glue dispensing cylinder is installed on the glue dispensing lifting component, and there is a glue storage space in the glue dispensing cylinder; the glue delivery hose is externally connected to a glue delivery pump and a glue delivery barrel for replenishing glue; the glue dispensing cover is threadedly connected to the glue dispensing cylinder, and the glue dispensing cover is provided with a joint connected to the glue delivery hose; the glue dispensing head is installed on the glue dispensing cylinder and is connected to the glue dispensing cylinder, and is located close to one end of the placement movable component.

[0009] By adopting the above technical solution, the glue delivery tube is used to provide glue replenishment for the glue dispensing cylinder, and the glue dispensing cylinder is opened through the glue dispensing cover for cleaning or dredging to prevent debris in the glue dispensing cylinder from clogging the glue dispensing head, and the glue dispensing head then transports the glue to the surface of the closed cover.

[0010] Optionally, the placement moving member includes a placement rail, a moving seat and a driving unit; the placement rail is installed on the workbench, and the moving seat is slidably connected to the placement rail; the driving unit is connected to the placement rail, and the driving end is connected to the moving seat.

[0011] By adopting the above technical solution, the driving part is used to drive the movable seat to move along the placement rail, and the placement seat is installed on the movable seat, so that the placement seat can move in a direction, reducing the situation of position deviation.

[0012] Optionally, a moving end of the placing movable member is provided with a replacement groove, and the placing seat is detachably connected to the placing movable member by means of the replacement groove.

[0013] By adopting the above technical solution, the replacement slot can be used to facilitate the replacement of the placement seat to adapt to window shaker closing covers of different styles and sizes or other required dispensing products, thereby improving the adaptability of the dispensing machine.

[0014] Optionally, a slidable clamping portion is provided at one end of the placement seat close to the slot opening of the replacement slot, and a locking portion is provided at one side of the slot opening of the replacement slot close to the placement movable member, and the clamping portion is clamped with the locking portion.

[0015] By adopting the above technical solution, when the placement seat is replaced through the replacement slot, the placement seat is inserted into the replacement slot. At this time, the clamping part is slid in the vertical direction so that the clamping part is inserted into the locking part, and the placement seat is locked in the replacement slot by the clamping part to prevent the placement seat from arbitrarily detaching from the replacement slot or moving from the replacement slot to cause the dispensing position to shift.

[0016] Optionally, the placement seat is slidably connected to a glue scraping portion near one end of the glue dispensing member.

[0017] By adopting the above technical solution, when the dispensing part dispenses glue to the closed cover on the placement seat, glue liquid will be retained in the specific dispensing path, affecting the dispensing of the next closed cover. Therefore, the scraper part is moved along the placement seat, and when it moves to the dispensing groove, the retained glue liquid is scraped out to avoid affecting the dispensing process of the next closed cover.

[0018] Optionally, the dispensing head is rotatably connected to a rotating part, and the placement seat is provided with a guiding part near the dispensing groove.

[0019] By adopting the above technical solution, when some closed covers have curved corners, deviation is prone to occur during the dispensing process. Therefore, when the deviation occurs, the rotating part contacts the guide part, causing the rotating part to roll along the surface of the guide part, thereby playing a guiding role and reducing the deviation.

[0020] Optionally, a buffer layer is provided on the surface of the rotating part and the contact surface between the guide part and the rotating part.

[0021] By adopting the above technical solution, the buffer layer can avoid the rigid collision caused by excessive deviation, and the provision of the buffer layer can avoid contact damage caused by excessive rigid connection.

[0022] In summary, the present application includes at least one of the following beneficial technical effects:

[0023] 1. The closed cover is stored in the dispensing slot of the placement seat, and the dispensing lifting member and the dispensing member are driven to move horizontally by the dispensing moving member. At the same time, the placement seat is driven by the placement moving member to move along the workbench toward the dispensing moving member, so that the dispensing lifting member drives the dispensing member to move in the vertical direction. According to the dispensing position required by the closed cover on the dispensing slot, the placement moving member drives the placement seat to move, and the dispensing moving member drives the dispensing member to move. The dispensing member provides dispensing synchronously, so that the dispensing member can flexibly adjust the dispensing position of the closed cover, thereby ensuring the accuracy of the dispensing position;

[0024] 2. When the dispensing part dispenses glue to the closed cover on the placement seat, the specific dispensing path will retain glue liquid, affecting the dispensing of the next closed cover. Therefore, the scraper is used to move along the placement seat. When it moves to the dispensing groove, the retained glue liquid is scraped out to avoid affecting the dispensing process of the next closed cover.

[0025] 3. After the placement seat is replaced through the replacement slot, the placement seat is inserted into the replacement slot. At this time, the clamping part is slid in the vertical direction so that the clamping part is inserted into the locking part, so that the placement seat is locked in the replacement slot by the clamping part to prevent the placement seat from arbitrarily leaving the replacement slot or moving from the replacement slot to cause the dispensing position to shift;

[0026] 4. When some closed covers have curved corners, deviation is prone to occur during the dispensing process. Therefore, at the same time as the deviation, the rotating part contacts the guide part, causing the rotating part to roll along the surface of the guide part, thereby playing a guiding role and reducing the deviation.

[0038] The following is combined with Figure 1 -Attached Figure 5 , further details of this application are given.

[0039] The embodiment of the present application discloses a glue dispensing machine for a window regulator closing cover.

[0040] A window regulator closing cover dispensing machine, referring to Figure 1 , including a workbench 1, a dispensing part 2, a dispensing lifting part 3, a dispensing moving part 4, a placement seat 5 and a placement moving part 6; the workbench 1 is divided into a base and a support frame, the support frame is installed on the base, and the dispensing moving part 4 is installed on the support frame, so that the dispensing moving part 4 is installed in the air, and the support frame is also provided with a controller, the dispensing lifting part 3 is connected to the moving end of the dispensing moving part 4, and the dispensing lifting part 3 can be horizontally moved through the dispensing moving part 4.

[0041] The glue dispensing component 2 is connected to the lifting end of the glue dispensing lifting component 3. The glue dispensing lifting component 3 can adopt a vertically arranged electric-driven linear guide rail. The glue dispensing component 2 has glue liquid built in it. The lifting end of the glue dispensing lifting component 3 can move the glue dispensing component 2 up and down in the vertical direction to transport the glue dispensing component 2 downward to the desired glue dispensing location. After glue dispensing, the glue dispensing component 2 is moved upward to adjust the height of the glue dispensing component 2.

[0042] The dispensing moving part 4 is used to adjust the horizontal position of the dispensing lifting part 3, and the dispensing lifting part 3 is used to adjust the vertical height of the dispensing part 2, so that the dispensing part 2 can move in three dimensions (that is, it can move left and right and up and down as needed), so that the dispensing part 2 can be adapted to different products for dispensing.

[0043] The placing movable part 6 is installed on the workbench 1 and is located below the dispensing movable part 4. The placing movable part 6 can adopt a linear guide driven by a stepping motor. The moving path of the placing movable part 6 is at a vertical angle to the moving path of the dispensing movable part 4, so that when the driving direction of the dispensing movable part 4 is left and right movement, the driving direction of the placing movable part 6 is forward and backward movement.

[0044] The placement seat 5 is installed at the moving end of the placement movable part 6, so that the placement seat 5 can be driven to move along the placement movable part 6 toward the front and rear direction of the workbench 1, and the placement seat 5 is provided with a dispensing groove 51 for placing the closing cover. Therefore, when the closing cover is placed in the dispensing groove 51, the placement seat 5 can drive the closing cover to move forward and backward, and the dispensing movable part 4 drives the dispensing part 2 to move left and right, so that it can adapt to different dispensing positions and ensure stable dispensing at the dispensing position.

[0045] Specifically, the closing cover is stored in the dispensing groove 51 of the placement seat 5, and the dispensing lifting member 3 and the dispensing member 2 are driven by the dispensing moving member 4 to move horizontally. At the same time, the placement seat 5 is driven by the placement moving member 6 to move along the workbench 1 toward the dispensing moving member 4, so that the dispensing lifting member 3 drives the dispensing member 2 to move in the vertical direction. According to the dispensing position required for the closed cover on the dispensing groove 51, the placement moving member 6 drives the placement seat 5 to move, and the dispensing moving member 4 drives the dispensing member 2 to move. The dispensing member 2 provides dispensing synchronously, so that the dispensing position of the closed cover by the dispensing member 2 can be flexibly adjusted, thereby ensuring the accuracy of the dispensing position.

[0046] For further reference, Figure 1 As shown, the placement movable member 6 includes a placement rail 61, a moving seat 62 and a driving part 63; the placement rail 61 is installed on the workbench 1, and the moving seat 62 is slidably connected to the placement rail 61. The placement rail 61 can adopt a T-shaped rail or an I-shaped rail. The moving seat 62 is adapted to the shape of the placement rail 61, so it can be restricted on the placement rail 61 and can slide along the placement rail 61.

[0047] The driving part 63 is connected to the placement rail 61, and the driving end is connected to the moving seat 62. The driving part 63 can adopt a motor and a screw (or lead screw). A threaded hole is opened on the moving seat 62, and the screw passes through the threaded hole. The driving end of the motor is connected to the screw, and the meshing transmission between the screw and the threaded hole is adopted, so that the moving seat 62 can move along the placement rail 61.

[0048] The driving part 63 can also use a driving source such as a cylinder or a telescopic cylinder to push the movable seat 62 along the placement rail 61.

[0049] Specifically, the driving unit 63 is used to drive the movable seat 62 to move along the placement rail 61 , and the placement seat 5 is installed on the movable seat 62 , so that the placement seat 5 can move in a directional manner to reduce position deviation.

[0050] In some embodiments, reference Figure 2 As shown, a replacement groove 64 is provided at the movable end of the placing movable part 6, and the placing seat 5 is detachably connected to the placing movable part 6 by means of the replacement groove 64. The replacement groove 64 can be a T-shaped groove, and a protrusion matching the replacement groove 64 can be provided at the bottom of the placing seat 5, so that the placing seat 5 can be inserted into the placing movable part 6 along the replacement groove 64, or pulled out from the placing movable part 6. The specific position of the replacement groove 64 can be on the top surface of the movable seat 62.

[0051] The replacement slot 64 can be used to facilitate replacement of the placement seat 5 to adapt to window regulator closing covers of different styles and sizes or other required dispensing products, thereby improving the adaptability of the dispensing machine.

[0052] Furthermore, a slidable clamping portion 53 is provided at one end of the placement seat 5 close to the slot of the replacement slot 64 , and the sliding direction of the clamping portion 53 is to move toward or away from the placement moving member 6 in the vertical direction.

[0053] A locking portion 65 is provided at the slot opening of the replacement slot 64 near the side where the movable part 6 is placed. The locking portion 65 and the clamping portion 53 are located on the same vertical line, so that the clamping portion 53 can be clamped with the locking portion 65. The clamping portion 53 adopts a clamping plate or a clamping block, and the locking portion 65 can adopt a locking ring or a lock buckle with a locking opening.

[0054] Specifically, after the placement seat 5 is replaced through the replacement groove 64, the placement seat 5 is inserted into the replacement groove 64 so that the clamping portion 53 and the locking portion 65 on the placement seat 5 are on the same vertical line. At this time, the clamping portion 53 is slid in the vertical direction so that the clamping portion 53 is inserted into the locking portion 65, thereby using the clamping portion 53 to lock the placement seat 5 in the replacement groove 64 to prevent the placement seat 5 from arbitrarily detaching from the replacement groove 64 or moving from the replacement groove 64 to cause the dispensing position to shift.

[0055] In some embodiments, reference Figure 3 As shown, the placement seat 5 is slidably connected to one end of the glue dispensing part 2 with a scraper portion 52, and the scraper portion 52 can be a scraper sheet or a scraper plate. The placement seat 5 is close to the glue dispensing part 2 at its top surface, and a limiting groove is set on the top surface of the placement seat 5. The scraper portion 52 is slidably connected to the placement seat 5 using the limiting groove.

[0056] When the glue dispensing part 2 dispenses glue to the closing cover on the placement seat 5, glue will remain in the specific glue dispensing path, affecting the glue dispensing of the next closing cover. Therefore, the glue scraping part 52 is moved along the placement seat 5. When it moves to the glue dispensing groove 51, the remaining glue is scraped out to avoid affecting the glue dispensing process of the next closing cover.

[0057] In some embodiments, reference Figure 4 As shown, the glue dispensing component 2 includes a glue delivery tube 21 , a glue dispensing cylinder 22 , a glue dispensing head 23 and a glue dispensing cover 24 ; the glue dispensing cylinder 22 is installed on the glue dispensing lifting component 3 , and there is a glue storage space in the glue dispensing cylinder 22 , and the glue can be temporarily stored in the glue dispensing cylinder 22 .

[0058] The glue delivery pipe 21 is externally connected to a glue delivery pump and a glue delivery barrel for replenishing glue liquid. After the glue delivery pipe 21 is externally connected to the glue delivery pump and the glue delivery barrel, the glue liquid in the glue dispensing cylinder 22 can be replenished. At the same time, the glue delivery pump can also be used to increase the pressure, so that the glue dispensing efficiency is improved.

[0059] The glue dispensing cover 24 is screwed to the glue dispensing tube 22, that is, an internal thread is provided inside the glue dispensing cover 24, and an external thread is provided on the outer surface of the glue dispensing tube 22. The glue dispensing cover 24 is screwed to the glue dispensing tube 22 by utilizing the screw connection effect of the internal and external threads. A joint connected to the glue delivery tube 21 is provided on the glue dispensing cover 24, and the joint is utilized to make the connection of the glue delivery tube 21 more stable.

[0060] The dispensing head 23 is installed on the dispensing cylinder 22 and is connected to the dispensing cylinder 22. It is located near one end of the movable part 6. The dispensing head 23 adopts a needle-shaped dispensing head 23. At the same time, the dispensing head 23 and the dispensing cylinder 22 are detachable to adjust the amount of glue removed during dispensing.

[0061] The glue delivery tube 21 is used to replenish the glue in the glue dispensing cylinder 22, and the glue dispensing cylinder 22 is opened through the glue dispensing cover 24 for cleaning or dredging to prevent debris in the glue dispensing cylinder 22 from clogging the glue dispensing head 23, and then the glue dispensing head 23 transports the glue to the surface of the closed cover.

[0062] In some embodiments, reference Figure 5 As shown, the dispensing head 23 is rotatably connected to a rotating part 231, and a guide part 54 is provided on the placement seat 5 near the dispensing groove 51. The rotating part 231 can adopt a rotating ball or a rotating bead, and a connecting port is provided in the middle of the rotating part 231. A mounting groove or a mounting bearing is provided on the surface of the dispensing head 23. The rotating part 231 is sleeved on the mounting groove or the mounting bearing using the connecting port, so that the rotating part 231 can rotate along the surface of the dispensing head 23.

[0063] The guide portion 54 may be a guide plate having a certain curvature, which is consistent with the moving path of the dispensing member 2 . The guide portion 54 may be disposed at a turning point of the dispensing groove 51 to provide guidance.

[0064] Specifically, when the dispensing head 23 of the dispensing component 2 descends to the dispensing groove 51 through the dispensing lifting component 3 to dispense glue to the closed cover, the placement moving component 6 and the dispensing moving component 4 respectively drive the placement seat 5 and the dispensing lifting component 3 and the dispensing component 2 to move to switch the dispensing position. However, when some closed covers have curved corners, deviations are likely to occur during the dispensing process. Therefore, while the deviation occurs, the rotating part 231 contacts the guide part 54, causing the rotating part 231 to roll along the surface of the guide part 54, thereby playing a guiding role and reducing the deviation.

[0065] Furthermore, a buffer layer is provided on the surface of the rotating part 231 and the contact surface between the guide part 54 and the rotating part 231. The buffer layer may be a rubber layer to avoid rigid collision caused by excessive deviation. The buffer layer can avoid contact damage caused by excessive rigid connection.

[0066] The guide part 54 is also provided with a pressure sensor. If the guide part 54 is subjected to excessive force and deflected when the rotating part 231 rolls, the pressure sensor can detect the pressure change and send out a warning signal, indicating that the dispensing path has deviated, reminding the worker to adjust it.

[0067] The embodiments of this specific implementation are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. The same components are represented by the same figure marks. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
