Description

Technical Field

[0002] The RGV trolley is a commonly used transfer tool in liquid injection and chemical formation equipment. The RGV trolley can transfer the liquid injection fixture from the liquid injection device to the static device. After the static device is completed, the RGV trolley will transfer the liquid injection fixture to the unloading station. Currently, most common RGV trolleys are single-sided transfer structures, that is, the liquid injection fixture can only be transferred on the same side of the RGV trolley, which affects the transportation efficiency of the RGV trolley and limits the spatial distribution of liquid injection and chemical formation equipment. In order to improve transportation efficiency and space utilization, some manufacturers design RGV trolleys that can be transferred in both directions. However, the designed RGV trolley has a limited transfer range and needs to be configured with multiple RGV trolleys for transfer.

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0026] In the description of the present invention, it should be understood that if the terms "center", "middle", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "axial", "radial", "circumferential" and the like appear, the orientation or position relationship indicated is based on the orientation or position relationship shown in the drawings, which is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention. In addition, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, unless otherwise specified, "multiple" means two or more.

[0027] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0028] The present invention relates to an RGV trolley, which includes a bidirectional transfer device, on which a liquid injection jig can be transferred along a first direction, and can also be transferred in the opposite direction along a second direction. Further, the RGV trolley includes a transfer lifting device, which is arranged in the frame of the RGV trolley, and the bidirectional transfer device is connected to the transfer lifting device. Specifically, a bidirectional transfer base 1000 in the bidirectional transfer device is connected to the transfer lifting device. Driven by the transfer lifting device, the bidirectional transfer device can be lifted and lowered, thereby transferring liquid injection jigs of different heights, and can also transfer the liquid injection jigs to different heights.

[0029] As an implementation mode, the transfer lifting device includes a transfer lifting driver 6101, which is connected to the frame of the RGV trolley. The transfer lifting driver 6101 is located on the top of the frame of the RGV trolley. The transfer lifting driver 6101 drives the bidirectional transfer device to rise and fall through a ball screw pair.

[0030] Specifically, the transfer lifting drive 6101 is configured as a motor, the two ends of the screw in the ball screw pair are respectively connected to the transfer lifting drive 6101 and the frame of the RGV trolley, and the nut in the ball screw pair is connected to the bidirectional transfer base 1000.

[0031] In order to enable the bidirectional transfer device to be lifted and lowered smoothly, the transfer lifting device includes a transfer lifting guide component 6102, and the bidirectional transfer base 1000 is slidably connected to the transfer lifting guide component 6102. In some examples, the transfer lifting guide component 6102 is set as a guide rail, and the bidirectional transfer base 1000 is connected to the transfer lifting guide component 6102 through a slider. In some examples, the transfer lifting guide component 6102 is set as a guide rod, and the bidirectional transfer base 1000 is connected to the transfer lifting guide component 6102 through a linear bearing.

[0032] In order to improve the lifting stability of the two-way transfer device, it is further designed that the transfer lifting device is set to multiple. In conjunction with the accompanying drawings, the transfer lifting device is set to two, and the two transfer lifting devices are respectively connected to the opposite sides of the two-way transfer base 1000.

[0033] The present invention relates to a liquid injection device, which includes an RGV trolley and an RGV transport rail 7100. The RGV trolley can move along the RGV transport rail 7100 to complete the transportation of the liquid injection fixture in the liquid injection device. It can be understood that the liquid injection device includes a stationary device and a liquid injection device. The liquid injection device injects liquid into the liquid injection cup in the liquid injection fixture, and the liquid injection fixture is transferred to the RGV trolley. The RGV trolley transfers the liquid injection fixture to the stationary device. After the stationary state is completed, the liquid injection fixture is transferred to the RGV trolley. The RGV trolley moves to a designated position along the RGV transport rail 7100, and the liquid injection fixture is sent out from the RGV trolley.

[0034] In some examples, the bidirectional transfer device on the RGV trolley can transfer the injection jig on one side of the RGV transport rail 7100 to the other side of the RGV transport rail 7100. In some examples, on the same side of the RGV transport rail 7100, the RGV trolley can also transport the injection jig from one end of the RGV transport rail 7100 to the other end through the bidirectional transfer device, or put down the injection jig along the RGV transport rail 7100.

[0035] It can be understood that the RGV trolley includes an RGV transport drive assembly, and driven by the RGV transport drive assembly, the RGV trolley can move along the RGV transport guide rail 7100.

[0036] In some examples, the RGV transport drive assembly includes an RGV transport drive 7201, an RGV transport transmission gear and an RGV transport transmission rack, the RGV transport drive 7201 is connected to the frame of the RGV trolley, the RGV transport transmission rack is connected to the base where the RGV transport guide rail 7100 is located, and the RGV transport transmission gear is connected to the RGV transport drive 7201. In some examples, the RGV transport drive 7201 includes a motor.

[0037] In conjunction with the accompanying drawings, the RGV transport drive assembly includes an RGV transport mounting plate 7202 , the frame of the RGV trolley is connected to the RGV transport mounting plate 7202 , and the RGV transport driver 7201 is connected to the RGV transport mounting plate 7202 .

[0038] Regarding the RGV transport drive assembly, as an alternative solution: in some examples, the RGV transport drive assembly drives the RGV trolley to move along the RGV transport guide rail 7100 through a transmission belt, and further, the RGV transport drive assembly drives the RGV trolley through a synchronous belt.

[0039] Supplementary explanation about the RGV trolley: if the RGV trolley is not equipped with a transfer lifting device, the bidirectional transfer device can move along the RGV transport rail 7100 and can also be used as an RGV trolley.

[0040] The other structures and operations of the RGV trolley and the liquid injection equipment have been recorded in the relevant technology for ordinary technicians in this field and will not be described in detail here. The structure of the bidirectional transfer device will be introduced below.

[0041] The invention relates to a bidirectional transport device, which can transport a liquid injection jig along a first direction and also transport the liquid injection jig along a second direction, and the first direction and the second direction are opposite, thereby realizing bidirectional transport of the liquid injection jig.

[0042] In conjunction with the accompanying drawings, the bidirectional transport device includes a bidirectional transport base 1000, a bidirectional transport support arm assembly 2000 and a bidirectional transport auxiliary assembly 3000. The bidirectional transport support arm assembly 2000 is arranged on the bidirectional transport base 1000, and the bidirectional transport auxiliary assembly 3000 is connected to the bidirectional transport support arm assembly 2000. In order to realize the transport of the injection fixture on the bidirectional transport device, the bidirectional transport support arm assembly 2000 is designed to be movable on the bidirectional transport base 1000, and the bidirectional transport auxiliary assembly 3000 can move relative to the bidirectional transport support arm assembly 2000.

[0043] Specifically, the bidirectional transfer auxiliary component 3000 moves relative to the bidirectional transfer arm component 2000 to pull the injection jig from one end of the bidirectional transfer arm component 2000 to the bidirectional transfer arm component 2000, the bidirectional transfer arm component 2000 moves on the bidirectional transfer base 1000 to transfer the injection jig, and the bidirectional transfer auxiliary component 3000 moves relative to the bidirectional transfer arm component 2000 to push the injection jig out of the bidirectional transfer arm component 2000 from the other end of the bidirectional transfer arm component 2000.

[0044] The bidirectional transport device includes a bidirectional transport drive assembly, which is respectively connected to the bidirectional transport base 1000 and the bidirectional transport arm assembly 2000, and the bidirectional transport drive assembly is used to drive the bidirectional transport arm assembly 2000 to move on the bidirectional transport base 1000. Specifically, the bidirectional transport drive assembly is used to drive the bidirectional transport arm assembly 2000 to move in a first direction and the bidirectional transport drive assembly is used to drive the bidirectional transport arm assembly 2000 to move in a second direction, thereby realizing a bidirectional transport liquid injection fixture.

[0045] In conjunction with the accompanying drawings, the two-way transport arm assembly 2000 includes an arm member 2301, which is used to carry the injection fixture. Under the drive of the two-way transport drive assembly, the arm member 2301 can move, and the arm member 2301 can extend from the two-way transport base 1000. It can be understood that if the location of the injection fixture or the location where the injection fixture is to be placed is far from the two-way transport base 1000, the two-way transport drive assembly can be used to drive the arm member 2301 to extend to expand the transport range.

[0046] It can be understood that in order to facilitate the bidirectional transport auxiliary component 3000 to pull or push the injection fixture to move on the bidirectional transport support arm component 2000, the bidirectional transport support arm component 2000 is designed to include a transport roller 2302, which is rollingly connected to the support arm component 2301. The transport roller 2302 is used to roll and support the injection fixture. In conjunction with the accompanying drawings, a plurality of transport rollers 2302 are provided. In some examples, the transport roller 2302 is provided with a ball or a roller.

[0047] As an embodiment, the bidirectional transfer drive assembly includes a bidirectional transfer drive 2101, a first transfer transmission gear 2102 and a first transfer transmission rack 2103. The bidirectional transfer drive 2101 is configured as a motor, the bidirectional transfer drive 2101 is connected to the bidirectional transfer base 1000, the first transfer transmission gear 2102 is connected to the output end of the bidirectional transfer drive 2101, the first transfer transmission gear 2102 is configured as a bevel gear, the first transfer transmission gear 2102 is meshed with the first transfer transmission rack 2103 for transmission, the first transfer transmission rack 2103 is connected to the bidirectional transfer arm assembly 2000, specifically, the first transfer transmission rack 2103 is connected to the lower side of the arm component 2301.

[0048] As for the bidirectional transport drive assembly, as an alternative, it can also be designed as follows: the bidirectional transport drive assembly drives the bidirectional transport support arm assembly 2000 to move back and forth through a transmission belt, specifically, the support arm component 2301 is connected to the transmission belt. Further, the transmission belt is set as a synchronous belt.

[0049] It is understandable that the two-way transfer arm assembly 2000 includes a two-way transfer guide component 2104, which is connected to the two-way transfer arm assembly 2000, and the two-way transfer guide component 2104 is slidably connected to the two-way transfer base 1000. In conjunction with the accompanying drawings, the two-way transfer guide component 2104 is set as a guide rail, the two-way transfer guide component 2104 is connected to the lower side of the arm assembly 2301, and the two-way transfer base 1000 is provided with a slider. Specifically, the slider is set on the column of the two-way transfer base 1000. On the one hand, the slider has the function of limiting and guiding the two-way transfer arm assembly 2000, and on the other hand, the slider and the column play a supporting role for the two-way transfer arm assembly 2000.

[0050] Regarding the bidirectional transfer guide component 2104, as an alternative, it can also be designed as follows: the bidirectional transfer guide component 2104 is set as a guide rod, the bidirectional transfer guide component 2104 is connected to the lower side of the support arm component 2301, and the bidirectional transfer base 1000 is provided with a linear bearing connected to the guide rod.

[0051] Further, the bidirectional transfer device includes a support arm supporting roller 1100, which is arranged on the bidirectional transfer base 1000, and the support arm supporting roller 1100 is used to support the bidirectional transfer support arm assembly 2000 to improve the stability of the bidirectional transfer support arm assembly 2000. In conjunction with the accompanying drawings, a column is arranged on the bidirectional transfer base 1000, and the support arm supporting roller 1100 is arranged on the top of the column. The support arm supporting roller 1100 supports the bidirectional transfer guide component 2104, and the support arm supporting roller 1100 is in rolling contact with the bidirectional transfer guide component 2104. It can be understood that during the movement of the bidirectional transfer support arm assembly 2000, the support arm supporting roller 1100 rolls and supports the side of the bidirectional transfer guide component 2104. In some examples, the support arm supporting roller 1100 is set as a roller or a rolling bearing.

[0052] As for the arm support roller 1100, as an alternative, it can also be designed that the arm support roller 1100 supports the two-way transport arm assembly 2000, and the arm support roller 1100 rolls with the two-way transport arm assembly 2000. Specifically, the arm support roller 1100 rolls and supports the lower side of the arm component 2301.

[0053] In conjunction with the accompanying drawings, two bidirectional transfer arm assemblies 2000 are provided, and the two bidirectional transfer arm assemblies 2000 are arranged side by side. The bottom of the injection fixture spans the two bidirectional transfer arm assemblies 2000, and the bidirectional transfer auxiliary assembly 3000 is arranged between the two bidirectional transfer arm assemblies 2000. The space reserved between the two bidirectional transfer arm assemblies 2000 can be used for the bidirectional transfer auxiliary assembly 3000 to move back and forth.

[0054] It is understandable that, driven by the bidirectional transport drive assembly, the two bidirectional transport support arm assemblies 2000 move synchronously. Specifically, the bidirectional transport driver 2101 is provided with two output ends, and the two output ends are respectively provided with a first transport transmission gear 2102.

[0055] Further, in order to make the two bidirectional transfer arm assemblies 2000 move synchronously, the bidirectional transfer device includes an arm connecting rod 2200, and the two ends of the arm connecting rod 2200 are respectively connected to the two bidirectional transfer arm assemblies 2000, specifically, the two ends of the arm connecting rod 2200 are respectively connected to the lower side of the arm component 2301. In conjunction with the drawings, two arm connecting rods 2200 are provided.

[0056] Regarding the bidirectional transfer arm assembly 2000, as an alternative, it can also be designed as follows: the bidirectional transfer arm assembly 2000 in the bidirectional transfer device is set as one, the bidirectional transfer arm assembly 2000 has two arm parts 2301, and the two arm parts 2301 are set on a larger mounting frame in the bidirectional transfer arm assembly 2000.

[0057] The bidirectional transport auxiliary component 3000 includes a bidirectional auxiliary push-pull component 3100. Along the first direction, both ends of the bidirectional auxiliary push-pull component 3100 are respectively provided with auxiliary push-pull connecting components 3101, and the auxiliary push-pull connecting components 3101 are used to connect the injection fixture. Specifically, the auxiliary push-pull connecting component 3101 protrudes from the upper side of the bidirectional auxiliary push-pull component 3100, and the auxiliary push-pull connecting component 3101 is connected to the bottom of the injection fixture.

[0058] Furthermore, in order to enable the two-way auxiliary push-pull component 3100 to smoothly pull or push the injection fixture, at least two auxiliary push-pull connecting components 3101 are respectively provided at both ends of the two-way auxiliary push-pull component 3100. In conjunction with the accompanying drawings, two two-way auxiliary push-pull arms are provided at the ends of the two-way auxiliary push-pull component 3100, one end of the two-way auxiliary push-pull arm is connected to the two-way auxiliary push-pull component 3100, and the other end is provided with an auxiliary push-pull connecting component 3101.

[0059] It can be understood that the bottom plate of the liquid injection jig is provided with a jig push-pull connection concave hole corresponding to the auxiliary push-pull connection part 3101. Specifically, the bottom plate of the liquid injection jig is provided with two groups of jig push-pull connection concave holes, which respectively correspond to the auxiliary push-pull connection parts 3101 at both ends of the two-way auxiliary push-pull part 3100. In some examples, the bottom plate of the liquid injection jig can also be designed to have a group of jig push-pull connection concave holes, and the auxiliary push-pull parts at both ends of the two-way auxiliary push-pull part 3100 are respectively connected to this group of jig push-pull connection concave holes to achieve pulling or pushing.

[0060] In order to enable the auxiliary push-pull connection component 3101 to be smoothly connected to and separated from the bottom of the injection fixture, the bidirectional auxiliary push-pull component 3100 is designed to be able to rise and fall. Specifically, the bidirectional transport auxiliary assembly 3000 includes a bidirectional transport auxiliary mounting plate 3200 and an auxiliary lifting driver 3301, the auxiliary lifting driver 3301 is connected to the bidirectional transport auxiliary mounting plate 3200, and the bidirectional auxiliary push-pull component 3100 is connected to the output end of the auxiliary lifting driver 3301. In some examples, the auxiliary lifting driver 3301 is set as a cylinder.

[0061] Furthermore, the auxiliary lifting actuator 3301 is provided in plurality, so that the bidirectional auxiliary push-pull component 3100 can be lifted and lowered stably and smoothly. In conjunction with the accompanying drawings, the auxiliary lifting actuator 3301 is provided in two.

[0062] It can be understood that when the two-way auxiliary push-pull component 3100 is moved into place, if the auxiliary push-pull connecting component 3101 needs to be separated from the bottom of the injection jig, the auxiliary lifting driver 3301 drives the two-way auxiliary push-pull component 3100 to descend; if the auxiliary push-pull connecting component 3101 needs to be connected to the bottom of the injection jig, the auxiliary lifting driver 3301 drives the two-way auxiliary push-pull component 3100 to rise.

[0063] In order to enable the bidirectional auxiliary push-pull component 3100 to be lifted and lowered smoothly, the bidirectional transport auxiliary assembly 3000 includes an auxiliary lifting guide component 3302, which is respectively connected to the bidirectional transport auxiliary mounting plate 3200 and the bidirectional auxiliary push-pull component 3100. In conjunction with the accompanying drawings, the auxiliary lifting guide component 3302 is set as a guide rod, the upper end of the auxiliary lifting guide component 3302 is fixedly connected to the bidirectional auxiliary push-pull component 3100, and the bidirectional transport mounting plate is provided with a linear bearing slidably connected to the auxiliary lifting guide component 3302. Further, the auxiliary lifting guide component 3302 is set in plurality to ensure that the bidirectional auxiliary push-pull component 3100 is lifted and lowered smoothly.

[0064] The bidirectional transfer device includes a bidirectional transfer auxiliary drive assembly, which is connected to the bidirectional transfer auxiliary assembly 3000 and the bidirectional transfer arm assembly 2000 respectively, and is used to drive the bidirectional transfer auxiliary assembly 3000 to move relative to the bidirectional transfer arm assembly 2000. Specifically, the bidirectional transfer auxiliary drive assembly is used to drive the bidirectional transfer auxiliary assembly 3000 to move relative to the bidirectional transfer arm assembly 2000 in a first direction, and the bidirectional transfer auxiliary drive assembly is used to drive the bidirectional transfer auxiliary assembly 3000 to move relative to the bidirectional transfer arm assembly 2000 in a second direction.

[0065] It is understandable that when the two-way auxiliary push-pull component 3100 in the two-way transport auxiliary component 3000 pulls the injection fixture onto the two-way transport support arm component 2000, and when the two-way auxiliary push-pull component 3100 pushes the injection fixture out of the two-way transport support arm component 2000, it is necessary to change the position of the two-way transport auxiliary component 3000 relative to the injection fixture, and also to switch the auxiliary push-pull connecting component 3101 of the two-way auxiliary push-pull component 3100 for connecting the injection fixture, so as to realize the handover of the two-way auxiliary push-pull component 3100. Therefore, it is necessary to design a two-way transport auxiliary drive component, which can drive the two-way transport auxiliary drive component to change the position of the two-way transport auxiliary component 3000 relative to the injection fixture, and on the other hand, can drive the two-way transport auxiliary drive component to pull or push the injection fixture.

[0066] As an embodiment, the bidirectional transfer auxiliary drive assembly includes a bidirectional transfer auxiliary driver 3401, a second transfer transmission gear 3402 and a second transfer transmission rack 3403. The bidirectional transfer auxiliary driver 3401 is configured as a motor. The bidirectional transfer auxiliary driver 3401 is connected to the bidirectional transfer auxiliary mounting plate 3200. The second transfer transmission gear 3402 is connected to the output end of the bidirectional transfer auxiliary driver 3401. The second transfer transmission gear 3402 is configured as a bevel gear. The second transfer transmission rack 3403 is connected to the bidirectional transfer support arm assembly 2000. Specifically, the second transfer transmission rack 3403 is connected to the support arm component 2301.

[0067] It is understandable that, driven by the bidirectional transport auxiliary driver 3401, the second transport transmission gear 3402 and the second transport transmission rack 3403 are meshed and transmitted, thereby driving the bidirectional transport auxiliary component 3000 to move relative to the bidirectional transport supporting arm component 2000. When the bidirectional transport auxiliary driver 3401 stops, the meshed gear teeth between the second transport transmission gear 3402 and the second transport transmission rack 3403 can play a fixing role, and the bidirectional auxiliary push-pull component 3100 plays a role in fixing and positioning the injection fixture to a certain extent, and the bidirectional transport supporting arm component 2000 prevents the position of the injection fixture from shifting during the movement.

[0068] Furthermore, in order to make the two-way transport auxiliary component 3000 move smoothly, the two-way transport supporting arm component 2000 is provided with a two-way transport auxiliary guide component 3404, and the two-way transport auxiliary mounting plate 3200 is slidably connected to the two-way transport auxiliary guide component 3404. Specifically, the two-way transport auxiliary guide component 3404 is connected to the supporting arm component 2301, the two-way transport auxiliary guide component 3404 is set as a guide rail, and the two-way transport auxiliary mounting plate 3200 is connected to the two-way transport auxiliary guide component 3404 through a slider. Of course, as an alternative, it can also be designed that: the two-way transport auxiliary guide component 3404 is set as a guide rod, and the two-way transport auxiliary mounting plate 3200 is provided with a linear bearing.

[0069] In the case where there are two bidirectional transport arm assemblies 2000: in some examples, one of the bidirectional transport arm assemblies 2000 is provided with a second transport transmission rack 3403, and the two bidirectional transport arm assemblies 2000 are respectively provided with a bidirectional transport auxiliary guide component 3404. In some examples, the two bidirectional transport arm assemblies 2000 are respectively provided with a second transport transmission rack 3403, the bidirectional transport auxiliary driver 3401 has two output ends, and the two bidirectional transport arm assemblies 2000 are respectively provided with a bidirectional transport auxiliary guide component 3404.

[0070] Regarding the bidirectional transfer auxiliary drive component, as an alternative, it can also be designed as follows: the bidirectional transfer auxiliary drive component drives the bidirectional transfer auxiliary component 3000 to move back and forth through a transmission belt, and further, the transmission belt is set as a synchronous belt.

[0071] The bidirectional transfer device includes a transfer auxiliary fixing component, which is connected to the bidirectional transfer base 1000. When it is necessary to change the position of the bidirectional transfer auxiliary component 3000 relative to the injection jig, the transfer auxiliary fixing component is used to fix the injection jig to prevent the injection jig from shifting in position on the bidirectional transfer arm assembly 2000.

[0072] Specifically, the transport auxiliary fixing assembly includes a transport auxiliary fixing device 5100, which is configured as a cylinder, and the push rod of the transport auxiliary fixing device 5100 can be pushed out to resist the side of the injection fixture. In conjunction with the accompanying drawings, the transport auxiliary fixing device 5100 is configured as two, and on the bidirectional transport base 1000, the two transport auxiliary fixing devices 5100 are arranged opposite to each other so as to clamp and fix the injection fixture. Specifically, the two transport auxiliary fixing devices 5100 are respectively arranged on opposite sides of the bidirectional transport base 1000, and the injection fixture passes between the two transport auxiliary fixing devices 5100.

[0073] Of course, regarding the transfer auxiliary fixing component, it can be understood that: in some examples, the transfer auxiliary fixing component is set to multiple, and along the transfer direction, each transfer auxiliary fixing component is arranged at intervals on the bidirectional transfer base 1000 so as to more firmly fix the position of the injection fixture.

[0074] The bidirectional transport device includes a first transport positioning sensor 4100, which is connected to the bidirectional transport base 1000 and is used to detect the moving position of the injection fixture on the bidirectional transport device. Specifically, the first transport positioning sensor 4100 is configured as a through-beam photoelectric sensor or a through-beam grating.

[0075] In some examples, two first transport positioning sensors 4100 are provided, and along the transport direction, the two first transport positioning sensors 4100 are spaced apart on the bidirectional transport base 1000. It can be understood that by using the two first transport positioning sensors 4100 to detect the position of the injection fixture, it is convenient to change the position of the bidirectional transport auxiliary component 3000 relative to the injection fixture, and realize the change of the bidirectional auxiliary push-pull component 3100.

[0076] In some examples, the bidirectional transfer device includes a second transfer positioning sensor, which is configured as a through-beam photoelectric sensor or a through-beam grating, and the second transfer positioning sensor is used to detect the moving position of the bidirectional transfer support arm assembly 2000. Specifically, when the bidirectional transfer support arm assembly 2000 is extended outward, if the second transfer positioning sensor is triggered, it means that the bidirectional transfer support arm assembly 2000 is extended to the right position.

[0077] In some examples, the bidirectional transport device includes a third transport positioning sensor, which is configured as a through-beam photoelectric sensor or a through-beam grating, and is used to monitor the moving position of the bidirectional transport auxiliary component 3000. Specifically, when the bidirectional transport support arm component 2000 is extended to the right position, in order to pull or push out the injection fixture, the bidirectional auxiliary push-pull component 3100 moves to a position relative to the extended position of the bidirectional transport support arm component 2000. If the third transport positioning sensor is triggered, it means that the bidirectional auxiliary push-pull component 3100 is extended to the right position.

[0078] The following is a detailed description of the process of transporting the injection jig by the bidirectional transfer device in the present invention using a specific embodiment. It should be noted that the following description is only an exemplary description and not a specific limitation of the present invention.

[0079] Combined with Figure 8 ,The operation process of the bidirectional transport method is as follows.

[0080] The injection jig to be transferred is located on one side of the bidirectional transfer device. If the injection jig to be transferred is far away from the bidirectional transfer device, the bidirectional transfer arm assembly 2000 extends along the first direction.

[0081] After the two-way transport support arm assembly 2000 is extended into place, the two-way transport auxiliary assembly 3000 moves along the first direction, and the two-way transport auxiliary assembly 3000 extends relative to the two-way transport support arm assembly 2000, so that the auxiliary push-pull connecting component 3101 at the first end of the two-way auxiliary push-pull component 3100 is connected to the injection fixture. It can be understood that before or during the movement of the two-way transport auxiliary assembly 3000 along the first direction, the two-way auxiliary push-pull component 3100 is in a descending position, and after the two-way transport auxiliary assembly 3000 is extended into place, the two-way auxiliary push-pull component 3100 rises so that the auxiliary push-pull connecting component 3101 can be connected to the lower side of the injection fixture.

[0082] After the auxiliary push-pull connection component 3101 is connected to the liquid injection jig, the bidirectional transfer auxiliary component 3000 moves along the second direction to pull the liquid injection jig onto the bidirectional transfer support arm component 2000.

[0083] The bidirectional transport arm assembly 2000 moves along the second direction to transport the injection fixture along the second direction. It is understandable that during this process, the bidirectional transport auxiliary assembly 3000 is stationary relative to the bidirectional transport arm assembly 2000, and the auxiliary push-pull connection component 3101 remains connected to the injection fixture, which can play a role in fixing the position of the injection fixture.

[0084] When the bidirectional transfer arm assembly 2000 transfers the liquid injection jig along the second direction, the first transfer positioning sensor 4100 monitors the moving distance of the liquid injection jig. If the moving distance of the liquid injection jig reaches the first set distance, the transfer auxiliary fixing assembly clamps and fixes the liquid injection jig.

[0085] The bidirectional auxiliary push-pull component 3100 descends, the bidirectional transport auxiliary component 3000 moves along the first direction to the bottom of the injection fixture, the bidirectional auxiliary push-pull component 3100 rises, and the auxiliary push-pull connecting component 3101 of the bidirectional auxiliary push-pull component 3100 is connected to the injection fixture.

[0086] The transfer auxiliary fixing component releases the fixation of the injection jig, and the bidirectional transfer auxiliary component 3000 moves along the second direction to push the injection jig to move on the bidirectional transfer arm component 2000. The first transfer positioning sensor 4100 monitors the moving distance of the injection jig. If the moving distance of the injection jig reaches the second set distance, the transfer auxiliary fixing component clamps and fixes the injection jig.

[0087] The bidirectional auxiliary push-pull component 3100 descends, the bidirectional transport auxiliary component 3000 moves along the first direction, and the bidirectional auxiliary push-pull component 3100 rises, so that the auxiliary push-pull connecting component 3101 at the second end of the bidirectional auxiliary push-pull component 3100 is connected to the injection fixture.

[0088] The transfer auxiliary fixing assembly releases the fixation of the liquid injection jig, and the bidirectional transfer arm assembly 2000 moves along the second direction to transfer the liquid injection jig along the second direction.

[0089] After the bidirectional transfer arm assembly 2000 is extended into place, the bidirectional transfer arm assembly 2000 stops moving, and the bidirectional transfer auxiliary assembly 3000 moves along the second direction to push the injection fixture out of the bidirectional transfer arm assembly 2000.

[0090] It should be noted that the first set distance and the second set distance monitored by the first transfer positioning sensor 4100 are obtained by monitoring two first transfer positioning sensors 4100. Specifically, the injection jig moves the first set distance to trigger the first first transfer positioning sensor 4100, and the injection jig continues to move the second set distance to trigger the second first transfer positioning sensor 4100.

[0091] In some examples, if the RGV trolley is moved by means of the RGV transport rail 7100, the injection fixture is transferred from one end to the other end on the same side of the RGV transport rail 7100. In this case, after the two-way transport auxiliary component 3000 pulls the injection fixture on one side of the RGV trolley onto the two-way transport support arm component 2000, the RGV trolley moves into position, and the two-way transport auxiliary component 3000 pushes the injection fixture to the same side of the RGV trolley.
