Description

Technical Field

[0001] This utility model relates to the field of storage equipment technology for electronic manufacturing production lines, and specifically to a jig buffer device and a jig buffer system. Background Technology

[0002] A jig is a widely used tool in industrial production, mainly used to assist in the processing, inspection, and assembly of products. To optimize production cycle time, some industrial production lines are equipped with buffer jig mechanisms. For example, in the inspection and assembly process of backlight modules, the required jigs are usually prepared in advance to ensure that certain processes can obtain the required jigs within the optimal time. Currently, in the production equipment of similar electronic products (such as mobile phones and laptops), buffering devices are set up to avoid product stacking on the production line. For example, Chinese invention patent document (CN118081317A) discloses a jig intelligent assembly equipment with buffering function, which connects the upper and lower sections of the production line through a buffer flow channel, and uses the buffer flow channel to perform slow storage and switching of jigs and base plates to reduce material accumulation.

[0003] However, the buffer flow channel of the intelligent assembly equipment with buffer function is relatively long, and its compartments are concentrated on one side, making it unsuitable for buffering larger jigs (such as jigs for OLED display devices, where a single jig can weigh up to 12kg). Utility Model Content

[0004] This invention provides a jig buffer device to solve the problem of insufficient load capacity in the prior art.

[0005] To solve the above-mentioned technical problems, the present invention provides a fixture buffer device, which includes a material frame, a transmission mechanism, and a lifting mechanism.

[0006] The material frame includes a storage space and side guards symmetrically arranged on both sides of the storage space. The side guards are provided with a plurality of support portions that can match the fixture along a first direction. The transmission mechanism is provided with a load-bearing fork arm that can extend or retract into the storage space along a second direction. The lifting mechanism is connected to the side guards and is used to drive the side guards to move along the first direction. The lifting mechanism includes a lifting motor and a first extension assembly and a second extension assembly symmetrically arranged on both sides of the storage space.

[0007] The beneficial effects of the technical solution provided by this utility model compared to the prior art are as follows:

[0008] The jig is supported by the support parts on the symmetrically arranged side guard plates, allowing it to be stably buffered within the storage space of the material frame and stacked along the first direction (height direction) to improve the utilization of storage space. The transmission mechanism works in conjunction with external transfer equipment (such as a robotic arm or gripping device) to receive the jig from the external transfer equipment and transport it to the buffer position in the storage space. Simultaneously, the lifting mechanism drives the side guard plates to rise, with the corresponding support parts cooperating with the jig to lift it upwards. Furthermore, the lifting mechanism is equipped with a lifting motor, which drives the first and second extension components to achieve synchronous lifting of the side guard plates and high load capacity.

[0009] In some implementations, the lifting mechanism is further provided with a plurality of guide posts that slide in cooperation with the side guard plate; wherein the first extension assembly and the second extension assembly include lead screws that are connected to the guide posts.

[0010] By employing the above technical solution, the stability of the side guard plate during its vertical movement is improved through the sliding engagement of multiple guide columns with the side guard plate. The lifting motor is driven by the lead screws of the first and second extension assemblies, which, compared to conventional belt or chain axial transmission methods, offers at least the following advantages:

[0011] (1) The lead screw has high precision in linear motion and can still achieve precise position control under heavy load; (2) The lead screw has strong axial load; (3) Both the first and second extension components use lead screws, which can achieve high synchronization under the drive of the same lifting motor.

[0012] In some implementations, the lifting mechanism includes a chain wound around the lifting motor, the first extension assembly, and the second extension assembly.

[0013] The above technical solution uses a chain as a transmission to further ensure the synchronization and high load capacity of the first and second top extension components. Specifically, the lifting motor drives the chain to rotate, thereby driving the lead screw and raising / lowering the side guard plate. The lifting motor and chain are located at the bottom of the material frame.

[0014] In some embodiments, the material frame includes a first material frame and a second material frame that are interconnected along a second direction, and the conveying mechanism passes through the first material frame and the second material frame along the second direction.

[0015] By adopting the above technical solution, the same transmission mechanism can have two buffer positions by changing the displacement stroke, and can respectively transport and store the fixture in the first material frame and the second material frame. The first material frame and the second material frame are both equipped with independent lifting mechanisms.

[0016] In some embodiments, the load-bearing fork arm is provided with a plurality of buffer support bars spaced apart along the second direction to support the fixture. Further, a pin mounting plate is provided between two adjacent buffer support bars along the second direction, and the pin mounting plate has pin mounting seats on both sides along the third direction for corresponding engagement with the positioning pins of the fixture.

[0017] By adopting the above technical solution, the positioning pin of the fixture is matched with the positioning pin of the fixture to ensure the precise positioning of the fixture when the external transfer equipment places it on the load-bearing fork arm, thereby ensuring that the fixture maintains the correct posture during the transfer process and when it is buffered in the support part of the side guard plate.

[0018] Furthermore, a positioning sensor is also provided on one side of the pin mounting base. Using the above technical solution, the positioning sensor can detect in real time whether the positioning pin is installed in place, ensuring the accurate positioning of the fixture.

[0019] In some embodiments, the material frame is further provided with a Z-axis sensing strip and a Z-axis sensing plate, the Z-axis sensing strip being located on the upper side of the transmission mechanism along the first direction.

[0020] By employing the above technical solution, the Z-axis sensing strip and Z-axis sensing plate work together to achieve precise monitoring of the side guard plate position, ensuring the normal operation of the lifting mechanism. Specifically, when buffering the fixture, the lifting mechanism drives the side guard plate upward, causing the support to lift the fixture until the load-bearing fork arm is unloaded, thereby buffering the fixture above the transmission mechanism.

[0021] In some implementations, the transmission mechanism further includes a stepper motor, wherein a Y-axis sensing plate is provided on the side of the load-bearing fork arm facing the stepper motor along the second direction.

[0022] By adopting the above technical solution, the position feedback of the stepper motor combined with the Y-axis sensor can realize the precise movement of the load-bearing fork arm in the second direction, so as to ensure that the load-bearing fork arm moves the fixture to the buffer position. The buffer position specifically refers to the spatial position that is aligned with the support part of the side guard plate in the first direction.

[0023] In some embodiments, this application also provides a fixture caching system, including a frame in which a plurality of the above-described fixture caching devices are arranged in an array within the frame.

[0024] The advantages of the technical solution provided by this utility model compared with the prior art are: by arranging multiple jig cache devices in an array within the frame, centralized management, efficient storage and space optimization of the jig are achieved, and it also has the advantages of high load capacity of the aforementioned cache jigs, which will not be elaborated here.

[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0039] For ease of subsequent description, before describing the specific structure of the jig buffer device and jig buffer system, this application will first combine... Figure 1 A first direction (Z), a second direction (Y), and a third direction (X) are defined. The first direction is the height direction of the jig buffer device when it is normally placed, such as the Z direction; the second direction is the width direction of the jig buffer device when it is normally placed, such as the Y direction; and the third direction is the length direction of the jig buffer device when it is normally placed, such as the X direction. In this application, the first direction (Z), the second direction (Y), and the third direction (X) are perpendicular to each other.

[0040] It is understood that the mutual perpendicularity in this application is not absolute perpendicularity. Approximate perpendicularity due to processing errors and assembly errors (e.g., the included angle between two structural features is 89.9°) is also within the scope of mutual perpendicularity in this application.

[0041] It is worth noting that the terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and are not limited in number; for example, the first object can be one or more.

[0042] See Figures 1 to 3 As shown, Figure 1 This invention provides a three-dimensional structural schematic diagram of an embodiment of a jig buffer device. Figure 2 This application provides a three-dimensional structural schematic diagram of an embodiment of a lifting mechanism 30 for a jig buffer device; Figure 3 A three-dimensional structural schematic diagram of an embodiment of the transmission mechanism 20 of a jig buffer device provided in this application is shown.

[0043] In some embodiments, the fixture buffer device includes a material frame 10, a transmission mechanism 20, and a lifting mechanism 30. The material frame 10 includes a storage space 11 and side guards 12 symmetrically arranged on both sides of the storage space 11, wherein the side guards 12 are provided with a plurality of support portions 120 that can match the fixture 40 at intervals along a first direction; the transmission mechanism 20 is provided with a load-bearing fork arm 21 that can extend or retract along a second direction into the storage space 11; the lifting mechanism 30 is connected to the side guards 12 and is used to drive the side guards 12 to move along the first direction, wherein the lifting mechanism 30 includes a lifting motor 31 and a first extension assembly 32 and a second extension assembly 33 symmetrically arranged on both sides of the storage space 11.

[0044] In this embodiment, the jig 40 is supported by the support portions 120 on the symmetrically arranged side guard plates 12, so that the jig 40 can be stably buffered in the storage space 11 of the material frame 10, and along the first direction ( Figure 1 Stacking (as shown in the Z-direction) improves the utilization of storage space 11. For example... Figure 1 As shown, one side guard plate 12 is provided with ten support parts 120, so two corresponding side guard plates 12 can jointly buffer and support ten jigs 40. However, this application does not limit the number of support parts 120, for example, it can also be set to 6, 8, etc. Exemplarily, the top of the material frame 10 is also provided with a baffle that can move up and down with the side guard plate 12 to prevent dust and debris from falling into the jigs 40.

[0045] In some application scenarios, the buffering step of fixture 40 is as follows: an external transfer device (such as a robotic arm or gripping device) transfers fixture 40 to the load-bearing forklift 21. The load-bearing forklift 21 receives fixture 40 from the external transfer device and moves fixture 40 to the buffer position in the storage space 11 (the buffer position specifically refers to the spatial position where the forklift moves to be aligned with the support portion 120 of the side guard plate 12 in the first direction). While the load-bearing forklift 21 is moving, the lifting mechanism 30 drives the side guard plate 12 to rise upward, and the corresponding support portion 120 cooperates with fixture 40 to lift fixture 40 upward.

[0046] In addition, combined Figure 2 As shown, the lifting mechanism 30 is equipped with a lifting motor 31. The lifting motor 31 drives the first extension component 32 and the second extension component 33 to achieve synchronous lifting and high load on the side guard plate 12. For example, the lifting motor 31 can be a 750W large motor and a reducer to meet the high load requirements. The side guard plate 12 can also be reinforced with a reinforcing plate on the side facing the guide column 34 to further improve the load capacity.

[0047] In some embodiments, the lifting mechanism 30 is further provided with a plurality of guide posts 34 that slide in cooperation with the side guard plate 12; wherein, the first extension assembly 32 and the second extension assembly 33 include lead screws 35 that are connected to the guide posts 34 respectively.

[0048] In this embodiment, the stability of the side guard plate 12 during its vertical movement is improved by using multiple guide posts 34 in sliding engagement with it. The lifting motor 31 is driven by the lead screw 35 of the first extension assembly 32 and the second extension assembly 33, which, compared to conventional axial transmission via belts or chains 36, offers at least the following advantages:

[0049] (1) The lead screw 35 has high precision in linear motion and can still achieve precise position control under heavy load; (2) The lead screw 35 has strong axial load; (3) The first extension assembly 32 and the second extension assembly 33 both use lead screw 35 and can have high synchronization under the drive of the same lifting motor 31.

[0050] In some embodiments, the lifting mechanism 30 includes a chain 36, which is wound around the lifting motor 31, the first extension assembly 32, and the second extension assembly 33.

[0051] In this embodiment, a chain 36 is used as a transmission to further ensure the synchronicity and high load capacity of the first lifting assembly 32 and the second lifting assembly 33. The lifting motor 31 and the chain 36 are located at the bottom of the material frame 10, combined with... Figure 4 As shown, Figure 4 This illustration shows a partially enlarged view of an embodiment of a lifting mechanism 30 for a jig buffer device provided in this application. The lifting motor 31 drives the chain 36 to rotate, thereby driving the lead screw 35 to lift the side guard plate 12.

[0052] In some implementations, the transmission mechanism 20 further includes a stepper motor 22, wherein a Y-axis sensing plate 214 is provided on the side of the load-bearing fork arm 21 facing the stepper motor 22 in the second direction.

[0053] In this embodiment, the position feedback of the stepper motor 22 combined with the Y-axis sensor 214 enables the precise movement of the load-bearing fork arm 21 in the second direction, so as to ensure that the load-bearing fork arm 21 moves the fixture 40 to the buffer position.

[0054] See Figure 5 As shown, Figure 5 A side view of an embodiment of a jig buffer device provided in this application is shown.

[0055] In some embodiments, the material frame 10 includes a first material frame 13 and a second material frame 14 that are interconnected along a second direction, and the conveying mechanism 20 passes through the first material frame 13 and the second material frame 14 along the second direction. In the embodiments of this application, the interconnected design of the first material frame 13 and the second material frame 14 allows the same conveying mechanism 20 to have two buffer positions by changing the displacement stroke, and can respectively transport and store the fixture 40 in the first material frame 13 and the second material frame 14. The first material frame 13 and the second material frame 14 are each provided with an independent lifting mechanism 30, an independent side guard plate 12, etc.

[0056] See Figure 3 and Figure 6 As shown, Figure 6 A three-dimensional structural schematic diagram of an embodiment of a load-bearing fork arm 21 of a jig buffer device provided in this application is shown.

[0057] In some embodiments, the load-bearing fork arm 21 is provided with a plurality of buffer support bars 210 spaced apart along the second direction to support the fixture 40. Further, a pin mounting plate 211 is provided between two adjacent buffer support bars 210 along the second direction, and the pin mounting plate 211 is provided with pin mounting seats 212 on both sides along the third direction for correspondingly engaging with the positioning pins of the fixture 40.

[0058] In this embodiment, the positioning pin of the fixture 40 is engaged with the pin of the mounting base 212 to ensure the precise positioning of the fixture 40 when the external transfer equipment places it on the load-bearing fork arm 21, thereby ensuring that the fixture 40 maintains the correct posture during the transfer process and when it is buffered in the support part 120 of the side guard plate 12.

[0059] Furthermore, a positioning sensor 213 is also provided on one side of the pin mounting base 212. In this embodiment, the positioning sensor 213 can detect in real time whether the positioning pin is installed in place, ensuring the accurate positioning of the fixture 40. Exemplarily, the positioning sensor 213 is a contact sensor, and its triggering method can be lever-type, plunger-type, or roller-type; this application does not limit this.

[0060] See Figure 2 and Figure 7 As shown, Figure 7 This illustration shows a partial structural enlarged schematic diagram of an embodiment of a jig buffer device provided in this application.

[0061] In some implementations, the material frame 10 is further provided with a Z-axis sensing strip 15 and a Z-axis sensing plate, with the Z-axis sensing strip 15 located above the transmission mechanism 20 along a first direction. In this embodiment, the cooperation of the Z-axis sensing strip 15 and the Z-axis sensing plate enables precise monitoring of the position of the side guard plate 12, ensuring the normal operation of the lifting mechanism 30. Specifically, when the buffer fixture 40 is in operation, the lifting mechanism 30 drives the side guard plate 12 to move upward, causing the support part 120 to lift the fixture 40 until the load-bearing fork arm 21 is unloaded, thereby buffering the fixture 40 above the transmission mechanism 20.

[0062] See Figure 8 As shown, Figure 8 A three-dimensional structural schematic diagram of an embodiment of a fixture caching system provided in this application is shown.

[0063] In some embodiments, this application also provides a fixture caching system, including a frame in which a plurality of the above-described fixture caching devices are arranged in an array within the frame.

[0064] The beneficial effects of the technical solution provided by this utility model compared with the prior art are: by arranging multiple jig cache devices in an array within the frame, the jig 40 is centrally managed, efficiently stored and space optimized, and has the advantages of high load capacity of the aforementioned cache jig 40, which will not be elaborated here.

[0065] For example, such as Figure 8 As shown, a single side panel 12 is provided with 10 support parts 120, then Figure 8 It can hold 60 jigs 40 and store them at the top of the frame. When a jig 40 needs to be removed, the transmission mechanism 20 moves the load-bearing fork arm 21 to the buffer position. The corresponding lifting mechanism 30 drives the side guard plate 12 to move down so that the jig 40 contacts the buffer support bar 210 of the load-bearing fork arm 21. Then, it reverses the action (the lifting mechanism 30 drives the side guard plate 12 to move down), so that the load-bearing fork arm 21 can be removed from the jig 40.

[0066] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, should be included within the protection scope of this utility model.
