Description

Technical Field

[0001] The present application relates to the technical field of manufacturing equipment, and in particular to an assembly workstation. Background Art

[0002] Most electronic devices on the market have a lighting function, so the manufacturing process involves a process of bonding the light strip to the back panel. At present, the commonly used method of bonding the light strip to the back panel is: the gluing operation and the light strip installation operation are separated into two separate stations, and the two stations are equipped with their own corresponding automated processing equipment, that is, a gluing robot is installed in the gluing station, and the gluing robot first performs gluing on the back panel, and then the back panel follows the conveyor line to the light strip pasting station, where the light strip pasting station needs to be equipped with a material picking robot and a worker at the same time. The worker first manually moves the light strip to the grabbing position, and the material picking robot grabs the light strip from the grabbing position and then moves it to the gluing position on the back panel to complete the assembly of the light strip and the back panel.

[0003] However, the above-mentioned traditional assembly and processing methods have the following defects and shortcomings: First, the dispensing station and the light strip pasting station need to be separately equipped with corresponding dispensing robots and grasping robots, resulting in a large number of equipment, a large footprint and high cost; secondly, the speed at which workers carry the light strips is slower than the speed at which the material-grabbing robots grasp the light strips. Therefore, in many cases, the material-grabbing robots will wait for workers to replenish materials, resulting in too long working intervals of the material-grabbing robots, low equipment utilization and work efficiency, and in the process of waiting for workers to replenish materials and waiting for the back panel that has completed dispensing to be transferred from the dispensing station to the light strip pasting station, the glue will also solidify prematurely due to long-term exposure to the air, affecting the subsequent bonding and assembly quality with the light strip. Summary of the invention

[0004] Based on this, it is necessary to provide an assembly workstation to address the problems of large floor space, high equipment investment cost, low work efficiency, and poor bonding assembly quality.

[0005] The present application provides an assembly workstation, which comprises:

[0006] A first conveying mechanism, the first conveying mechanism is used to convey a first material to a bonding station along a first direction;

[0010] The assembly workstation of the above scheme is applied to the processing occasions where the first material and the second material are bonded and assembled into one. During production and processing, the first conveying mechanism is used to convey the first material to the bonding station, and the first material stops and waits after arriving at the bonding station; at the same time, the second conveying mechanism conveys the second material to the material picking station, and then the assembly execution robot grabs the second material from the material picking station and quickly transfers it to the gluing station, and the gluing mechanism fixedly installed in the gluing station then performs gluing processing on the second material. After the gluing processing is completed, the assembly execution robot immediately moves the second material to the bonding station, and bonds and assembles the second material to the preset position of the first material, thereby completing the bonding and assembly processing of the first material and the second material. Compared with the prior art, the present solution only uses one assembly execution robot to continuously complete a series of process steps such as material picking, gluing and bonding assembly.

Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of the features. In the description of this application, if the term "plurality" appears, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0036] In this application, unless otherwise clearly specified and limited, if the terms "installed", "connected", "connected", "fixed" and the like appear, these terms should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integrated connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined.

[0039] In the related art, the processing method for gluing and assembling the light strip to the back panel is as follows: the gluing operation and the light strip installation operation are separated into two separate workstations, and the two workstations are respectively equipped with corresponding automated processing equipment, that is, a gluing robot is installed in the gluing station 70, and the gluing robot first performs gluing on the back panel, and then the back panel follows the conveyor line to the light strip pasting station, wherein the light strip pasting station needs to be equipped with a material picking robot and a worker at the same time, and the worker first manually moves the light strip to the grabbing position, and the material picking robot grabs the light strip from the grabbing position and then moves and pastes it to the gluing position on the back panel, thereby completing the assembly of the light strip and the back panel.

[0040] However, the glue dispensing station 70 and the light strip pasting station need to be separately configured with corresponding glue dispensing robots and grasping robots, resulting in a large number of equipment, a large footprint and high cost. In addition, the speed at which workers carry light strips is slower than the speed at which the material-grabbing robot grasps the light strips. Therefore, in many cases, the material-grabbing robot will wait for workers to replenish materials, resulting in too long working intervals of the material-grabbing robot, low equipment utilization and work efficiency, and in the process of waiting for workers to replenish materials and waiting for the back panel that has been glued to flow from the glue dispensing station 70 to the light strip pasting station, the glue will also solidify prematurely due to long-term exposure to the air, affecting the subsequent bonding and assembly quality with the light strip.

[0041] Therefore, in order to solve the above problems, the present application proposes an optimized implementation scheme that can realize the bonding and assembly of the light strip and the back panel.

[0042] Specifically, see Figure 1, which is an assembly workstation 100 shown in one embodiment of the present application, includes a first conveying mechanism 10, a second conveying mechanism 30, a dispensing mechanism 50 and an assembly execution robot 60.

[0043] The first conveying mechanism 10 is used to convey the first material 200 to the bonding station 20 along a first direction.

[0044] The first direction specifically refers to Figure 1 The direction of the arrow F1 in FIG. 1 is consistent with the longitudinal direction of the entire assembly workstation 100 .

[0045] It can be understood that in this solution, the first material 200 adopts a back panel, and the inner wall of the back panel is provided with a light bar bonding position, and the light bar bonding position is used to bond and fix the light bar so that the electronic device installed with the back panel has a light-emitting function.

[0046] It should be noted that the bonding station 20 in this solution does not refer to a physical object, but can be understood as a processing space or place where the light strip and the back panel are bonded to each other.

[0047] The second conveying mechanism 30 is used to convey the second material to the material taking station 40 along the second direction.

[0048] The second direction specifically refers to Figure 1 The direction of the arrow F2 in FIG. 1 is consistent with the horizontal direction of the entire assembly workstation 100 .

[0049] It is understandable that the second material in this solution is a light bar. The light bar can be an LED light bar, which is more helpful for energy saving and consumption reduction during work.

[0050] It should also be noted that the material-retrieving station 40 in this solution does not refer to a physical object, but can be understood as a space or place for temporarily storing light strips and for the assembly execution robot 60 to obtain the light strips.

[0051] Please continue reading Figure 1 In some embodiments, the first conveying mechanism 10 includes a first bracket 11, and the second conveying mechanism 30 includes a second bracket 31. The first bracket 11 and the second bracket 31 are arranged to intersect each other, and the first direction corresponds to the length extension direction of the first bracket 11, and the second direction corresponds to the length extension direction of the second bracket 31.

[0052] For example, in this embodiment, the height of the second bracket 31 is greater than the height of the first bracket 11, and the second bracket 31 has a through hollow cavity, and the first bracket 11 passes through the hollow cavity so that the second bracket 31 and the first bracket 11 are arranged to intersect. In this way, the volumes of the first bracket 11 and the second bracket 31 overlap in space, thereby greatly reducing the occupied site area, making the overall structure of the assembly workstation 100 more compact, and helping to expand the applicable scenarios.

[0053] In addition, the first bracket 11 and the second bracket 31 both adopt a simple frame structure, which is easy to manufacture and low in cost, but can ensure sufficient structural strength and service life.

[0054] The glue dispensing mechanism 50 is fixed in the glue dispensing station 70 and arranged on one side of the first conveying mechanism 10; the assembly execution robot 60 is used to grab the second material in the material picking station 40 and transfer it to the glue dispensing station 70, so that the glue dispensing mechanism 50 performs glue dispensing processing on the second material, and the assembly execution robot 60 then bonds the second material that has completed the glue dispensing processing to the first material 200.

[0055] In summary, the implementation of the technical solution of this embodiment will have the following beneficial effects: the assembly workstation 100 of the above-mentioned solution is applied to the processing occasions where the first material 200 and the second material are bonded and assembled into one. During production and processing, the first conveying mechanism 10 is used to convey the first material 200 to the bonding station 20, and the first material 200 stops and waits after arriving at the bonding station 20; at the same time, the second conveying mechanism 30 conveys the second material to the material picking station 40, and then the assembly execution robot 60 grabs the second material from the material picking station 40 and quickly transfers it to the glue dispensing station 70, and the glue dispensing mechanism 50 fixedly installed in the glue dispensing station 70 immediately performs glue dispensing processing on the second material. After the glue dispensing processing is completed, the assembly execution robot 60 immediately moves the second material to the bonding station 20, and bonds and assembles the second material to the preset position of the first material 200, thereby completing the bonding and assembly processing of the first material 200 and the second material.

[0056] Compared with the prior art, the present solution only uses one assembly execution robot 60 to continuously complete a series of process steps such as material picking, gluing and bonding assembly. Firstly, the number of equipment is reduced, the floor space is reduced, and the equipment investment cost is reduced. Secondly, the continuity of each process step in the entire processing process is high. When the second material is glued, it will be quickly bonded to the first material 200. The waiting time in the middle is short, and the glue will not solidify prematurely to affect the bonding assembly quality of the first material 200 and the second material. In addition, the assembly execution robot 60 has high working efficiency.

[0057] Please continue reading Figure 1 On the basis of the above embodiment, the first conveying mechanism 10 further includes a conveying wheel set 12 , which is mounted on the first bracket 11 and is used to convey the first material 200 .

[0058] During operation, the back panel is placed on the conveying wheel set 12, and the conveying wheel set 12 rotates to horizontally drive the back panel to move along the first direction to enter the bonding operation, so that the conveying method of the back panel is simple and reliable.

[0059] Optionally, the conveying wheel group 12 can be a power combination of a motor and a pulley group, or the conveying wheel group 12 can include multiple motors, multiple driving wheels and multiple driven wheels, the motors are connected to the driving wheels one by one, the driving wheels and the driven wheels are alternately extended in the first direction and arranged at intervals, the motor drives the driving wheel to rotate and drive the back plate to move, and the driven wheel takes over the driving wheel to support the back plate and transmit it, and so on.

[0060] Please continue reading Figure 1 , Figure 4 and Figure 6 On the basis of any of the above embodiments, the second conveying mechanism 30 also includes a first loading tray 32, a second loading tray 33, a transmission module 34 and a driver 35, and the two ends of the second bracket 31 in the length direction are respectively set as a loading end and a picking end, and the picking end extends into the picking station 40.

[0061] The driver 35 is installed on the second bracket 31, the transmission module 34 is movably arranged on the second bracket 31 and connected to the driver 35, the first loading tray 32 and the second loading tray 33 are both connected to the transmission module 34, and the transmission module 34 is used to drive the first loading tray 32 and the second loading tray 33 to rotate one-to-one with the loading end and the picking end respectively.

[0062] During operation, at least one staff member will be configured at the loading end to manually load the light strips into the first loading tray 32 and the second loading tray 33. For example, when the first loading tray 32 is full and the second loading tray 33 is empty, the driver 35 is started and drives the first loading tray 32 and the second loading tray 33 to move through the transmission module 34, so that the first loading tray 32 moves to the material collection end, and the assembly execution robot 60 can pick up the light strips from the first loading tray 32; at the same time, the second loading tray 33 will move to the loading end, and the staff will replenish the light strips into the second loading tray 33, so that the light strips can be replenished while ensuring the synchronous material collection operation of the assembly execution robot 60, avoiding waiting intervals and affecting the utilization rate and work efficiency of the assembly execution robot 60.

[0063] Furthermore, when the light bars in the first loading tray 32 are taken out and the light bars in the second loading tray 33 are filled up at the same time, the transmission module 34 can further drive the first loading tray 32 and the second loading tray 33 to switch positions with each other, so that the full second loading tray 33 moves to the material taking end and the empty first loading tray 32 moves to the material loading end, thereby ensuring that the assembly execution robot 60 can continuously take materials from the second loading tray 33, and at the same time ensuring that the staff replenishes the light bars in the first loading tray 32 in time. In this way, the first loading tray 32 and the second loading tray 33 are driven by the driver 35 and the transmission module 34 to continuously switch positions, thereby ensuring that the assembly workstation 100 can continuously process without stopping, improving the utilization rate of the assembly execution robot 60, and improving the work efficiency of the assembly workstation 100.

[0064] Optionally, the driver 35 can be any one of a motor, a cylinder, etc.; the transmission module 34 can be any one of a screw nut, a gear rack, etc. For example, a cylinder is connected to a gear rack, the gear rack is meshed with the gear, the first loading tray 32 and the second loading tray 33 are both installed on the end face of the gear, and the gear rack drives the gear to rotate 180°, so that the first loading tray 32 and the second loading tray 33 can be driven to rotate to alternate working positions.

[0065] Alternatively, the motor is connected to the lead screw, which has two nuts threaded on it. The two nuts are connected one-to-one with the first loading tray 32 and the second loading tray 33. The motor drives the lead screw to rotate, and the lead screw drives the nut to move forward and backward along the axial direction of the lead screw, thereby driving the first loading tray 32 and the second loading tray 33 to move back and forth in a straight line to switch the working positions.

[0066] Please continue reading Figure 2 Furthermore, in order to ensure that the first loading tray 32 and the second loading tray 33 move smoothly and have a stable posture after arriving at the material picking station 40, and to ensure that the assembly execution robot 60 grabs the light strip safely and reliably, the second conveying mechanism 30 also includes a slide rail 36 and a guide block 37, the slide rail 36 is arranged on the second bracket 31, the guide block 37 is arranged on the first loading tray 32 and the second loading tray 33, the guide block 37 is installed on the slide rail 36 and can slide relative to the slide rail 36, or the second conveying mechanism 30 also includes a slide rail 36 and a guide block 37, the slide rail 36 is arranged on the first loading tray 32 and the second loading tray 33, the guide block 37 is arranged on the second bracket 31, and the guide block 37 is installed on the slide rail 36 and can slide relative to the slide rail 36.

[0067] Please continue reading Figure 1 and Figure 5In addition, based on any of the above embodiments, the assembly execution robot 60 includes a flexible robotic arm 61 and a material picking and placing fixture 62, and the material picking and placing fixture 62 is installed at the end of the flexible robotic arm 61, and the flexible robotic arm 61 is used to drive the material picking and placing fixture 62 to move cyclically between the material picking station 40, the glue dispensing station 70 and the bonding station 20.

[0068] The flexible robotic arm 61 can specifically adopt a multi-axis robotic arm, such as any one of a three-axis robotic arm, a five-axis robotic arm, etc. Since the flexible robotic arm 61 has more degrees of freedom in movement and rotation, it has higher mobility flexibility, so it can drive the material picking and placing fixture 62 to move quickly and accurately between the material picking station 40, the glue dispensing station 70 and the bonding station 20 in the optimal path, avoiding interference problems and ensuring the accuracy of material picking, glue dispensing and bonding processing.

[0069] Please continue reading Figure 2 , Figure 3 and Figure 6 Specifically, in some embodiments, the material picking and placing fixture 62 includes a mounting seat 621 and at least two material picking and placing actuators 622, and the at least two material picking and placing actuators 622 are mounted on the mounting seat 621. The dispensing mechanism 50 includes a carrier plate 51 and at least two dispensing actuators 52, and the at least two dispensing actuators 52 are mounted on the carrier plate 51. When the material picking and placing fixture 62 is in the dispensing station 70, the material picking and placing actuators 622 and the dispensing actuators 52 are arranged one by one.

[0070] At least two slots are provided in the first loading tray 32 and the second loading tray 33, each slot is used to place a light strip, and the number, structure, size, etc. of the slots are adapted to the material picking and placing actuator 622, so that the material picking and placing fixture 62 can pick up at least two light strips at a time through at least two material picking and placing actuators 622, and the gluing process can be completed by at least two gluing actuators 52 at the same time, so that at least two light strips that have completed gluing can be bonded to the back panel at the same time, which greatly improves the processing efficiency.

[0071] Optionally, the glue dispensing actuator 52 may be any one of a glue nozzle, a glue gun, etc.

[0072] Optionally, in some embodiments, the material picking and placing fixture 62 also includes a vacuum generator, which is installed on the mounting seat 621, and the material picking and placing actuator 622 is configured as a vacuum suction cup, which is directly connected to the vacuum generator or indirectly connected through a vacuum pipeline.

[0073] Usually, the lampshade material of the light bar is glass, which is brittle and has low strength. Therefore, a vacuum suction cup is used to absorb and grasp the light bar to avoid the risk of the light bar being damaged by the physical clamping force. At the same time, the method of absorbing, grasping and releasing the light bar is simple and reliable.

[0074] It should be noted that when the light strip is a cylinder, the suction hole of the vacuum suction cup is preferably designed to match the outer cylindrical surface of the light strip to form an inner concave arc structure, thereby increasing the adsorption area between the vacuum suction cup and the light strip to enhance the adsorption stability of the vacuum suction cup on the light strip.

[0075] In order to ensure that the material picking and placing fixture 62 can be accurately aligned with the glue dispensing actuator 52 after it moves to the glue dispensing station 70, on the basis of the above embodiment, the assembly workstation 100 also includes a positioning member and a sensor. The positioning member is installed on one of the mounting seat 621 and the carrier plate 51, and the sensor is installed on the other of the mounting seat 621 and the carrier plate 51. When the material picking and placing fixture 62 is in the glue dispensing station 70, the positioning member and the sensor cooperate with each other.

[0076] For example, the positioning member is a touch piece, and the sensor is a laser sensor. When the touch piece is facing the laser sensor and blocks the light of the laser sensor, it indicates that the material taking and placing actuator 622 and the glue dispensing actuator 52 are aligned.

[0077] Furthermore, in some other embodiments, the dispensing mechanism 50 also includes a distance adjustment component 53, which is mounted on the carrier plate 51 and connected to at least two dispensing actuators 52, and the distance adjustment component 53 is used to adjust the distance between two adjacent dispensing actuators 52.

[0078] Because different light strips have different specifications and generally different sizes, the spacing between the light strips is different, and the spacing of the material picking and placing actuators 622 will also change accordingly. Therefore, the spacing of the dispensing actuators 52 is made adjustable by designing the distance adjustment component 53, thereby meeting the dispensing needs of light strips of different specifications and sizes, thereby expanding the scope of application of the assembly workstation 100.

[0079] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0080] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
