Technical Field

[0001] This utility model relates to the field of automotive door sealing corner joining machine technology, and in particular to an injection device for an automotive door sealing corner joining machine. Background Technology

[0002] Currently, most automotive door sealing corner welding machines in China use hydraulic anti-fall injection devices. When the injection device is raised to its highest position, a hydraulic valve controls the up and down movement of the injection device cylinder to prevent it from falling. However, the hydraulic valve cannot completely prevent falling, and there is a risk of operator safety accidents caused by the hydraulic valve failing and the injection device falling. Utility Model Content

[0003] The main purpose of this invention is to provide an injection device for an automotive door seal corner joint machine, which aims to prevent the material cylinder from falling and improve the safety of material cylinder operation.

[0004] To achieve the above objectives, the present invention provides an injection device for automotive door seal corner joining, comprising: The material barrel injects the rubber material into the mold; An injection seat, wherein the material cylinder is mounted on the injection seat, and the injection seat is sleeved on the guide post and can move up and down along the guide post; An anti-drop mechanism is installed on the moving template. The anti-drop mechanism includes a support frame. When the support frame is in a first position, the injection seat can move up and down along the guide post, and the support frame is located outside the vertical projection range of the barrel. When the support frame is in a second position, the injection seat is restricted to move up and down along the guide post, and the support frame is located within the vertical projection range of the barrel.

[0005] In one embodiment, the support frame is reciprocally movably disposed on the movable template along a first direction. The anti-fall mechanism further includes a guide bar and a slider. The guide bar is disposed on the movable template and extends along the first direction. The slider is disposed on the support frame and slides in cooperation with the guide bar along the first direction. The first direction and the vertical direction are intersected.

[0006] In one embodiment, there are two guide bars, which are located on both sides of the support frame. There are also two sliders, which are located on both sides of the support frame. The two sliders slide in a one-to-one manner with the two guide bars.

[0007] In one embodiment, the guide bar has a groove extending in a first direction on the side near the support frame, and the slider is slidably mounted in the groove.

[0008] In one embodiment, the anti-fall mechanism further includes a positioning component, which includes a positioning element and a positioning mating element. The positioning element is disposed on the support frame, and the positioning mating element is disposed on the movable template and located at one end of the guide strip. The positioning element is used to engage with the positioning mating element when the support frame is in a first position to limit the movement of the support frame. The positioning element can be separated from the positioning mating element under the action of an external force so that the support frame can be moved from the first position to a second position.

[0009] In one embodiment, the anti-fall mechanism further includes a limiting part disposed on the moving template. The limiting part is located at the end of the guide strip away from the positioning mating member, and the limiting part is used to abut against the support frame when the support frame is in the second position.

[0010] In one embodiment, one of the positioning member and the positioning mating member is configured as a ball bearing and the other is configured as a ball bearing seat; The contact ball is magnetically attracted to the contact ball seat; or, the contact ball is snapped into place with the contact ball seat.

[0011] In one embodiment, the support frame has a support surface and a gripping portion. The support surface is located on the side of the support frame away from the moving template. When the support frame is in the second position, the support surface is used to support the material cylinder to limit the injection seat from moving downward along the guide post. The gripping portion is located on the side of the support surface close to the moving template.

[0012] In one embodiment, the grip portion includes a rod portion and groove portions located on both sides of the rod portion.

[0013] In one embodiment, the automotive door sealing corner injection device further includes a locking mechanism, a proximity switch, and a control device, wherein the control device is electrically connected to the locking mechanism and the proximity switch; The locking mechanism is used to lock the barrel to restrict the barrel from sliding up and down, or to unlock the barrel so that the barrel can slide up and down. The proximity switch is located on the moving template. When the support frame is within the sensing range of the proximity switch, the support frame is in a first position, and the control device is used to control the locking mechanism to unlock the material cylinder. When the support frame is outside the sensing range of the proximity switch, the support frame is in a second position, and the control device is used to control the locking mechanism to lock the material cylinder.

[0014] The technical solution of this utility model involves setting a material cylinder installed on an injection seat, setting the injection seat to be sleeved on a guide post and allowing the guide post to move up and down, and setting an anti-drop mechanism on a moving template for an automotive door seal corner fitting machine injection device. The anti-drop mechanism includes a support frame. When the support frame is in a second position, the injection seat is restricted from moving up and down along the guide post, and the support frame is located within the vertical projection range of the material cylinder. When the support frame is in a first position, the injection seat can move up and down along the guide post, and the support frame is located outside the vertical projection range of the material cylinder. Thus, by setting the support frame in the second position, mechanical support is provided for the material cylinder when it falls, and by setting the support frame in the first position, which is outside the vertical projection range of the material cylinder, the support frame does not interfere with the vertical movement of the material cylinder. When the automotive door seal corner fitting machine injection device is working, the safety of the material cylinder during operation is improved, and the accidental drop of the material cylinder is avoided.

[0022] Currently, most automotive door sealing corner welding machines in China use hydraulic anti-fall injection devices. When the injection device is raised to its highest position, a hydraulic valve controls the up and down movement of the injection device cylinder to prevent it from falling. However, the hydraulic valve cannot completely prevent falling, and there is a risk of operator safety accidents caused by the hydraulic valve failing and the injection device falling.

[0023] This utility model proposes an injection device 1000 for automotive door sealing corner jointing machine.

[0024] Please see Figures 1 to 4In one embodiment of this utility model, the automotive door seal corner joint injection device 1000 includes a material cylinder 201, an injection seat 203, and an anti-drop mechanism 100. The material cylinder 201 injects adhesive into the mold. The material cylinder 201 is mounted on the injection seat 203. The injection seat 203 is sleeved on the guide post 202 and can move up and down along the guide post 202. The anti-drop mechanism 100 is disposed on the moving template 10. The anti-drop mechanism 100 includes a support frame 20. When the support frame 20 is in a first position, the injection seat 203 can move up and down along the guide post 202, and the support frame 20 is located outside the vertical projection range of the material cylinder 201. When the support frame 20 is in a second position, the injection seat 203 is restricted to move up and down along the guide post 202, and the support frame 20 is located within the vertical projection range of the material cylinder 201.

[0025] The movable template 10 can be located directly below the barrel 201. The support frame 20 can slide horizontally on the movable template 10 to reciprocate between a second position and a first position. When the barrel 201 moves vertically along the guide post 202 via the injection seat 203 to its highest point, the support frame 20 can be in the second position. At this time, the support frame 20 can be located below the barrel 201, within the vertical projection range of the barrel 201. If the support frame 20 accidentally falls, it can support the barrel 201. When the support frame 20 moves from the second position to the first position under the action of external force, the support frame 20 can be outside the vertical projection range of the barrel 201, and the barrel 201 can reciprocate vertically, allowing the support frame 20 to avoid the movement of the barrel 201. The first position can be the position where the support frame 20 is outside the vertical projection range of the barrel, and the second position can be the position where the support frame 20 is within the vertical projection range of the barrel 201. The external force that moves the support frame 20 between the first position and the second position can be a push or pull force that manually moves the support frame 20, or a driving force that drives the support frame 20 to move by setting a driving component; no specific limitation is made here.

[0026] When the support frame is located at the first position outside the vertical projection range of the material cylinder 201, the operator can avoid interference with the movement of the material cylinder 201 when the material cylinder 201 needs to be moved. When the operator needs to repair or clean the material in the material cylinder 201, the material cylinder 201 can be raised to the highest point and locked, and then the support frame 20 can be moved from the first position to the second position. The support frame 20 is located within the vertical projection range of the material cylinder 201, and supports the material cylinder 201 when it falls, limiting the material cylinder 201 from falling downwards. The mechanical anti-fall function can limit the material cylinder 201, preventing the material cylinder 201 from falling due to the failure of the built-in hydraulic anti-fall function.

[0027] The technical solution of this utility model is achieved by setting an injection device 1000 for an automotive door seal corner fitting machine, including a material cylinder 201, which is mounted on an injection seat 203. The injection seat 203 is sleeved on a guide post 202 and allows the guide post 202 to move up and down. The injection device 1000 also includes an anti-drop mechanism 100 on a moving template 10, which includes a support frame 20. When the support frame 20 is in a second position, the injection seat 203 is restricted from moving up and down along the guide post. The support frame is located within the vertical projection range of the material cylinder. In the first position, the injection seat 203 can move up and down along the guide post, and the support frame is located outside the vertical projection range of the barrel. Thus, by placing the support frame 20 in the second position, mechanical support can be provided for the barrel 201 when it falls. And by placing the support frame 20 in the first position outside the vertical projection range of the barrel 201, the support frame 20 does not interfere with the up and down movement of the barrel 201. When the automotive door sealing corner injection device 1000 is working, the safety of the barrel 201 during operation can be improved, and the accidental fall of the barrel 201 can be avoided.

[0028] like Figure 1 , Figure 2 As shown, in one embodiment, the support frame 20 is reciprocally movably disposed on the movable template 10 along a first direction. The anti-fall mechanism 100 further includes a guide strip 40 and a slider 50. The guide strip 40 is disposed on the movable template 10 and extends along the first direction. The positioning mating member 32 is located at one end of the guide strip 40. The slider 50 is disposed on the support frame 20 and slides in cooperation with the guide strip 40 along the first direction. The first direction and the vertical direction are intersected.

[0029] The first direction can be the front-back direction, located on a horizontal plane and intersecting with the up-down direction. The guide bar 40 can be set on the left and right sides of the support frame 20. A sliding groove 41 extending in the front-back direction can be opened on the guide bar 40, so that the slider 50 can be slidably installed in the sliding groove 41. Thus, through the sliding cooperation between the guide bar 40 and the slider 50, the support frame 20 is guided to move in the front-back direction, realizing movement between the first position and the second position. This facilitates the movement of the support frame 20 along a specified trajectory, preventing the support frame 20 from deviating from its active position and failing to provide effective support for the material cylinder 201. At the same time, it prevents the positioning part 31 and the positioning mating part 32 from failing to engage accurately, which would cause the support frame 20 to fail to be effectively locked and interfere with the up-down movement of the material cylinder 201.

[0030] Of course, in other embodiments, the guide bar 40 may also be disposed at the bottom of the support frame 20. No limitation is made here.

[0031] like Figure 1 , Figure 2 As shown, in one embodiment, there are two guide bars 40, which are located on both sides of the support frame 20. There are also two sliders 50, which are located on both sides of the support frame 20. The two sliders 50 slide in a one-to-one manner with the two guide bars 40.

[0032] In this way, two guide bars 40 are respectively set on both sides of the support frame 20. When the support frame 20 moves in the first direction, both sides have sliding support, so that the guide bars 40 are balanced by force, making the support frame 20 move more smoothly in the first direction.

[0033] like Figure 1 As shown, in one embodiment, the guide bar 40 has a groove 41 extending in a first direction on the side near the support frame 20, and the slider 50 is slidably mounted in the groove 41.

[0034] It is understandable that since the guide bar 40 is set on the left and right sides of the support frame 20, the slide groove 41 is also located on the left and right sides of the support frame 20. When the support frame 20 is in the second position and supports the material cylinder 201, the support frame 20 is subjected to downward pressure, which will not directly act on the slide groove 41 on the left and right sides of the support frame 20. This can prevent the slide groove 41 from being deformed by pressure, thereby ensuring the service life of the guide bar 40.

[0035] like Figure 2 As shown, in one embodiment, the anti-fall mechanism 100 further has a limiting part 11 provided on the moving template 10. The limiting part 11 is located at the end of the guide strip 40 away from the positioning mating member 32. The limiting part 11 is used to abut against the support frame 20 when the support frame 20 is in the second position.

[0036] The limiting part 11 can be a limiting groove formed on the moving template 10, and the support frame 20 can be limited and engaged with the limiting groove by the slider 50. With this arrangement, the two ends of the guide bar 40 are respectively provided with positioning fittings 32 and limiting parts 11. When the support frame is in the first position, the positioning fittings 32 and positioning fittings 31 on the support frame 20 can engage to restrict the support frame 20 from sliding out of the guide bar 40. When the support frame 20 is in the second position, the limiting parts 11 can abut against the support frame 20 to restrict the support frame 20 from sliding out of the guide bar 40, thereby limiting the movement stroke of the support frame 20.

[0037] like Figure 1 , Figure 2As shown, in one embodiment, the anti-fall mechanism further includes a positioning component 30, which includes a positioning element 31 and a positioning mating element 32. The positioning element 31 is disposed on the support frame 20, and the positioning mating element 32 is disposed on the movable template 10 and located at one end of the guide strip 40. The positioning element 31 is used to engage with the positioning mating element 32 when the support frame 20 is in a first position to limit the movement of the support frame 20. The positioning element 31 can separate from the positioning mating element 32 under the action of external force so that the support frame 20 can move from the first position to the second position.

[0038] Understandably, since the positioning element 31 is located on the support frame 20 and the positioning mating element 32 is located on the moving template 10, when the positioning element 31 and the positioning mating element 32 are engaged, the support frame 20 can be positioned in the first position, restricting the movement of the support frame 20. This prevents the support frame 20 from being unable to be effectively fixed and interfering with the movement of the material cylinder 201 when the operator needs to move it. When the operator needs to repair or clean the adhesive in the material cylinder 201, the support frame 20 can be moved from the first position to the second position, causing the positioning element 31 and the positioning mating element 32 to separate without interfering with the movement of the support frame 20. The support frame 20 can provide support for the material cylinder 201, preventing the material cylinder 201 from falling downwards.

[0039] The structure of the positioning element 31 and the positioning mating element 32 is described below. Optionally, one of the positioning element 31 and the positioning mating element 32 is configured as a ball bearing, and the other is configured as a ball bearing seat.

[0040] The ball bearing can be mounted on the support frame 20, and the ball bearing seat can be mounted on the movable template 10, or the ball bearing can be mounted on the movable template 10 and the ball bearing seat can be mounted on the support frame 20; no specific limitation is made here. The ball bearing can have a protrusion, and the ball bearing seat can have a ball groove and a metal ball that can move elastically within the ball groove. During the process of the protrusion engaging with the ball groove, the protrusion presses against the metal ball, causing the metal ball to retract and then spring back, thus engaging the protrusion within the ball groove. The support frame 20 is positioned in the first position. When the protrusion separates from the ball groove under the action of external force, the support frame 20 moves from the first position to the second position.

[0041] Alternatively, the contact ball may magnetically engage with the contact ball seat; or, the contact ball may snap-fit ​​with the contact ball seat. When the contact ball and the contact ball seat are magnetically engaged, the contact ball in the groove of the contact ball seat and the protrusion of the contact ball may magnetically engage. When the contact ball and the contact ball seat are snap-fit, the contact ball in the groove of the contact ball seat and the protrusion of the contact ball may snap-fit, thereby achieving the engagement and positioning between the two. No specific limitation is made here.

[0042] like Figure 2As shown, in one embodiment, the support frame has a support surface 21 and a gripping part 22. The support surface 21 is located on the side of the support frame 20 away from the moving template 10. When the support frame 20 is in the second position, the support surface 21 is used to support the material cylinder 201 to limit the injection seat 203 from moving downward along the guide post 202. The gripping part 22 is located on the side of the support surface 21 close to the moving template 10.

[0043] Thus, the operator can move the support frame 20 to the second position by holding the grip part 22 in the first direction. The support surface 21 can support the cylinder 201 when the locking mechanism for the cylinder 201 fails and the cylinder 201 falls, thereby restricting the injection seat 203 connected to the cylinder 201 from moving downward along the guide post 202. It is understood that since the grip part 22 is located on the side of the support surface 21 closer to the moving template 10, the grip part 22 is far from the bottom surface of the cylinder 201. When the operator moves the support frame 20 by operating the grip part 22, it can prevent the operator's hand from being pinched when the cylinder 201 presses down onto the support surface 21.

[0044] like Figure 2 As shown, in one embodiment, the gripping part 22 includes a rod 221 and grooves 222 located on both sides of the rod 221. Thus, an operator can insert their thumb into one groove 222 and their other four fingers into the other groove 222 to grip the rod 221. When the two grooves 222 are spaced apart in the vertical direction, there is a gap between each groove 222 and the support surface 21, thereby preventing the support frame 20 from pinching the hand when supporting the material cylinder 201.

[0045] In addition, in this utility model, the moving template has an injection port, the material cylinder 201 can move up and down above the injection port, and the two guide bars 40 of the anti-drop mechanism 100 are located on opposite sides of the radial direction of the injection port.

[0046] like Figure 2 , Figure 3 , Figure 4 As shown, optionally, the automotive door sealing corner injection device 1000 further includes a locking mechanism, a proximity switch 300, and a control device, wherein the control device is electrically connected to the locking mechanism and the proximity switch 300; The locking mechanism is used to lock the material cylinder 201 to restrict the material cylinder 201 from sliding up and down, or to unlock the material cylinder 201 so that the material cylinder 201 can slide up and down. The proximity switch 300 is located on the moving template 10. When the support frame 20 is within the sensing range of the proximity switch 300, the support frame 20 is in a first position, and the control device is used to control the locking mechanism to unlock the material cylinder 201. When the support frame 20 is outside the sensing range of the proximity switch 300, the support frame 20 is in a second position, and the control device is used to control the locking mechanism to lock the material cylinder 201.

[0047] The locking mechanism can be a hydraulic anti-drop structure integrated into the injection unit 1000 of the automotive door sealing corner machine, and the control device can be an MCU that controls the opening and closing of the hydraulic anti-drop structure. The proximity switch 300 can be located at the position of the moving template 10 near the positioning mating part 32.

[0048] When the support frame 20 moves to the first position and the positioning member 31 engages with the positioning mating member 32, the support frame 20 approaches the proximity switch 300 located on the moving template 10 and is within the sensing range of the proximity switch 300. The proximity switch 300 senses the support frame 20 and transmits a proximity signal to the control device. The control device sends a closing command to the locking mechanism based on the proximity signal, controlling the locking mechanism to unlock the material cylinder 201, allowing the material cylinder 201 to move freely up and down. When the support frame 20 moves out of the first position and is in the second position, the positioning member... When the support frame 20 separates from the positioning and mating part 32, it moves away from the proximity switch 300 and is outside the sensing range of the proximity switch 300. The proximity switch 300 cannot sense the support frame 20, indicating that the support frame 20 is in the second position. At this time, the proximity switch 300 transmits a distance signal to the control device. The control device sends an opening command to the locking mechanism based on the distance signal, controlling the locking mechanism to lock the material cylinder 201 to prevent the material cylinder 201 from falling. Together with the support frame 20 in the second position, it can prevent the material cylinder from falling, thus playing a double anti-fall protection role.

[0049] The above description is merely an exemplary embodiment of the present utility model and does not limit the scope of protection of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the scope of protection of the present utility model.
