Description

Gluing assembly system

Technical Field

The utility model relates to the technical field of gluing, in particular to a gluing assembly system.

Background

In assembling vehicle accessories, such as circuit boards for vehicles, it is necessary to encapsulate the circuit boards in a protective case to prevent the circuit boards from being contaminated with substances from the outside environment. Generally, the protective case includes an upper half case and a lower half case, and the upper half case may be bonded to the lower half case by performing a gluing operation to form a chamber accommodating the circuit board.

Currently, in order to ensure the correct implementation of the gluing operation, it is necessary to determine the weight of the glue immediately after it has been applied to one of the upper and lower half-shells, which is the part to be glued, and therefore, before the gluing operation, it is necessary to move the part to be glued, which has not been applied with glue, to a weighing station for weighing, while after the gluing operation, it is still necessary to move the part to be glued, which has been applied with glue, to the same or a different weighing station for weighing. However, moving the parts to be glued multiple times before and after performing the gluing operation is disadvantageous in terms of improving the assembly efficiency and may negatively affect the gluing quality.

In addition, in the process of assembling the circuit board, optical inspection operation, lamination operation, ray inspection operation and the like are required to be implemented in addition to the gluing operation, so that the assembly of the upper half shell and the lower half shell is finally completed.

Detailed Description

Various exemplary embodiments of the present utility model will now be described in detail with reference to the accompanying drawings. It should be noted that: the relative arrangement of the components and steps, numerical expressions and numerical values set forth in these embodiments do not limit the scope of the present utility model unless it is specifically stated otherwise.

In all examples shown and discussed herein, any specific values should be construed as merely illustrative, and not a limitation. Thus, other examples of exemplary embodiments may have different values.

It should be noted that: like reference numerals and letters denote like items in the following figures, and thus once an item is defined in one figure, no further discussion thereof is necessary in subsequent figures.

Referring to fig. 1, an exemplary glue assembly system 10 (hereinafter simply referred to as an assembly system) is adapted to assemble a first component 12 to a second component 14 (not shown in fig. 1) shown in fig. 3, the assembly system 10 comprising a circular console 16, a first clamp 18 being provided on a circumferential edge of the circular console 16, the first clamp 18 being adapted to clamp the first component 12. For example, a plurality of first jigs 18 may be circumferentially disposed equidistantly on the circumferential edge of the circular operation table 16 to fit a plurality of first members 12 to a plurality of second members 14 in a batch one-to-one correspondence. The circular table 16 is rotatable about its center axis 16a, and the first clamp 18 is capable of moving to an upstream position a, a midstream position B, and a downstream position C, which are sequentially adjacent on the circumferential edge of the circular table 16, by means of rotation of the circular table 16, with care being taken that the coordinate points of these positions are fixed, i.e., the coordinate points of these positions do not change with rotation of the circular table 16, but coincide with or are aligned with the positions on the circumferential edge of the circular table 16 where the first clamp 18 is provided, these positions being named according to the fitting process of the first member 12 to the second member 14. It will be appreciated that the upstream, downstream and downstream positions a, B and C may be coincident or aligned with any suitable position on the circumferential edge of the circular console 16, depending on the particular application scenario.

Referring to fig. 2, in general, rotation of the circular table 16 may be accomplished by means of a drive combination of a servo motor 20, a conveyor belt (not shown), and a gear drive 22, as is currently known. The rotation speed and the steering of the servo motor 20 are controlled by the signal voltage, and when the magnitude and the polarity of the signal voltage are changed, the rotation speed and the steering of the servo motor 20 are also changed. On the one hand, the conveyor belt connects the servo motor 20 to the input end 22a of the gear train 22 to synchronously rotate the input end 22a of the gear train 22 according to the rotational speed and the steering direction of the servo motor 20. The advantage of using a conveyor belt is that: reducing vibration of the circular console 16 during rotation; the rotation of the circular operation table 16 is more stable and accurate; the probability of abnormal conditions such as locking and slipping of the circular operation table 16 in the rotating process is reduced; low maintenance cost, etc. On the other hand, the output end 22b of the gear transmission mechanism 22 is connected to the center axis 16a of the circular console 16 to drive the circular console 16 to rotate by a desired angle.

To this end, the assembly system 10 further includes a control device 24, e.g., a PLC programmed control device 24, configured to be communicatively coupled to known sensors 26 mounted on the servo motor 20 to obtain the number of rotations of the servo motor 20 from such sensors 26, and to control the servo motor 20 in accordance with the correspondence between the number of rotations of the servo motor 20 and the desired angle of rotation of the circular console 16 such that the rotation of the circular console 16 by the desired angle causes the first clamp 18 on the circumferential edge of the circular console 16 to move accurately and smoothly to the upstream position a, the intermediate position B and the downstream position C.

In addition, the assembly system 10 further comprises gluing and weighing means 28, optical inspection means 30, lamination means 32, and optionally radiographic inspection means 34, etc., which are intended to carry out the different operations of assembling the first component 12 to the second component 14, distributed on the basis of the circular operating table 16 and its surrounding environment, so as to achieve an automatic integration of the assembly system 10.

With continued reference to fig. 2, the gluing and weighing device 28 is provided separately from the circular operating table 16, the gluing and weighing device 28 being relatively independent and comprising, in comparison to the other devices: a second clamp 36 adapted to clamp the first component 12; a manipulator 38 disposed adjacent the upstream position a and the midstream position B and adapted to transfer the first part 12 between the first clamp 18 and the second clamp 36, the control device 24 may be communicatively connected to the manipulator 38, for example, such that the manipulator 38 may transfer the first part 12 that has not been glue coated from the first clamp 18 to the second clamp 36 in a state in which the first clamp 18 is moved to the upstream position a, and transfer the first part 12 that has been glue coated from the second clamp 36 to the first clamp 18 in a state in which the first clamp 18 is moved to the midstream position B; a glue head 40, which is arranged above the second clamp 36 and is adapted to apply glue (also called glue) to the first component 12 clamped by the second clamp 36; a weighing module 42, e.g., an electronic weighing module, disposed below the second clamp 36 and adapted to weigh the first part 12 clamped by the second clamp 36, e.g., the weighing module 42 may weigh a first weight of the first part 12 clamped by the second clamp 36 while the first part 12, which is not glue coated, is transferred from the first clamp 18 to the second clamp 36, and weigh a second weight of the first part 12 clamped by the second clamp 36 immediately before the first part 12, which has been glue coated, is transferred from the second clamp 36 to the first clamp 18. The first part 12, clamped by the second clamp 36, remains stationary during gluing and weighing, to ensure the correct implementation of the gluing operation.

In this context, the weighing module 42 has been zeroed-adjusted with respect to the second fixture 36 fixed thereto, such that the weighing module 42 weighs the total weight of the first component 12 carried by the second fixture 36 and, optionally, the glue coated on the first component 12, based on currently known principles. The control device 24 may be communicatively connected to the weighing module 42 and configured to receive information from the weighing module 42 regarding the first weight and the second weight to determine the weight of glue that has been applied to the first component 12 based on the difference between the second weight and the first weight. In the event that the weight of the glue is not within the threshold range, the control device 24 may also control the robot arm 38 to remove the first part 12 from the second clamp 36 to discard the failed first part 12, and the assembly system 10 may additionally include an alarm device 44 communicatively coupled to the control device 24, the control device 24 will simultaneously control the alarm device 44 to issue a corresponding alarm in the event that the weight of the glue is not within the threshold range.

By way of example only, and not limitation, the first and second members 12 and 14 herein are the lower and upper halves of a protective housing, respectively, that may be used to encapsulate a vehicle circuit board to prevent contamination of the circuit board by materials from the external environment. For example, to mount the first component 12 to the second component 14 to form a cavity for receiving a circuit board, the first component 12 may have a first interface and the second component 14 may have a second interface, and an amount of glue may be applied to the first interface of the first component 12 by the glue head 40, and then the first interface of the first component 12 may be pressed against the second interface of the second component 14 to securely bond the first component 12 to the second component 14.

Since the first interface is generally shaped with a contoured glue slot to receive the glue, the glue head 40 and/or the second clamp 36 should be movable, for example in at least one of six degrees of freedom, so that the glue head 40 applies the glue to the first part 12 clamped by the second clamp 36 in a pre-set trajectory. The control device 24 may be communicatively coupled to the applicator head 40 and/or the second clamp 36 to control movement of the applicator head 40 and/or the second clamp 36.

Optionally, in order for the gluing and weighing device 28 to perform the gluing and weighing operations in a relatively independent environment, the gluing and weighing device 28 further comprises: a closure cap 48 having an opening 46, the chamber formed by the closure cap 48 housing the second clamp 36, the glue head 40, the weighing module 42, and optionally any other associated components of the glue and weighing device 28; and a cover 50 capable of opening and closing the opening 46, whereby the cover 50 is provided on the cover 48 in a switchable manner with respect to the opening 46 by means of a switching mechanism 50a (not shown), the switching mechanism 50a causing the cover 50 to close the opening 46 in a state where the gluing and weighing operation is performed, and the switching mechanism 50a causing the cover 50 to open the opening 46 in a state where the robot arm 38 operates to transfer the first member 12 between the first clamp 18 located on the circular table 16 and the second clamp 36 located on the gluing and weighing device 28. The control device 24 may be communicatively coupled to the switching mechanism 50a to control the operation of the switching mechanism 50 a.

Optionally, the glue and weighing device 28 further comprises a cushioning pad 52, such as a foam, sponge, or the like, positioned underneath the weighing module 42 to prevent the weighing module 42 from vibrating to adversely affect the accuracy of the weighing module 42. Because of the small weight of glue applied to the first part 12, a high sensitivity and accuracy of the weighing module 42 is required. In addition, the glue and weigh device 28 may be supported by a marble platform 54 to help keep the glue and weigh device 28 stationary during operation.

The relatively independent gluing and weighing device 28, which is not in cooperation with the circular operating table 16, allows better gluing operations to be performed herein.

Returning to fig. 1, the optical inspection device 30 is arranged with respect to the midstream position B and is adapted to detect the application result of said glue. For example, the optical inspection device 30 may be disposed above or near the midstream position B to enable capturing of the glue coated first part 12 gripped by the first gripper 18 at the midstream position B. As is known, the optical inspection Device 30 comprises a camera with a CCD (Charge-coupled Device)/camera system high-precision function to be able to take images of the first component 12 already coated with glue, for example, images relating to the glue-application position or glue-application width of critical parts of the first component 12 already coated with glue can be snap-shot. The control device 24 may be communicatively connected to the camera to determine 100% on-line the uniformity of the glue, the air bubbles, the glue track in the glue slot of the first component 12 after the gluing and weighing operations have been performed by acquiring these images, the control device 24 may compare the preset glue area and track with the actual glue area and track taken by the camera; and/or the control device 24 may convert the preset glue application area into a theoretical value of the glue application width, so as to compare with the actual glue application width photographed by the camera, so as to determine whether the glue application result meets the requirement.

Optionally, the assembly system 10 may further include an additional robot 56 communicatively coupled to the control device 24 to control the additional robot 56 to remove the first component 12 from the first clamp 18 at the midstream location B to discard the failed first component 12 in a state where the glue application results are not satisfactory. Additionally, the control device 24 can also control the alarm device 44 to give a corresponding alarm in a state in which the glue application result does not meet the requirements.

Referring to fig. 3, the assembly system 10 further includes a bonding device 32 disposed relative to the downstream location C and adapted to bond the second component 14 to the first component 12 clamped by the first clamp 18 to enable the glue to bond the first component 12 to the second component 14.

The pressing device 32 comprises a third clamp 33 arranged above, in particular directly above, the downstream position C, the third clamp 33 being adapted to clamp the second component 14 and being reciprocally movable at least along a vertical axis defined by a support bar 35 of the pressing device 32 to press the second component 14 in alignment to the first component 12 already coated with glue, as shown in fig. 3, the vertical axis L being parallel to the rotation axis H of the circular table 16 at the circular spindle 16 a.

In this context, the first clamp 18, the second clamp 36, and the third clamp 33 may be configured according to various types of clamps currently known, for example, the first clamp 18, the second clamp 36, and the third clamp 33 may each have a jaw that may releasably clamp the first component 12 by way of a form fit and/or friction fit. Additionally or alternatively, the first clamp 18, the second clamp 36, and the third clamp 33 may also be magnetically attractive clamps.

Returning to fig. 1, optionally, the first clamp 18 is further configured to be movable after the downstream position C to a further downstream position D adjacent to the downstream position C on the circumferential edge of the circular table 16 by means of rotation of the circular table 16, while the assembly system 10 further comprises a radiographic inspection device 34 arranged with respect to the further downstream position D. As is known, the radiographic inspection device 34 comprises, for example, an X-ray emitter, the radiographic inspection device 34 being adapted to detect the adhesion result of the glue. For example, a radiation inspection device 34, in particular an X-ray emitter, may be arranged above or near the downstream position C to be able to emit radiation towards the glue coated first component 12 gripped by the first gripper 18 at the further downstream position D, in particular towards critical local glue sites on the glue coated first component 12. The control device 24 may be communicatively connected to the radiation inspection device 34 to determine the curing state of the glue in the glue slot of the first component 12 after the lamination operation is performed, etc. by acquiring information about the radiation, the curing state of the glue, etc. being indicative of the glue bonding result.

Optionally, the assembly system 10 may further include an additional robot 58 communicatively coupled to the control device 24 to control the additional robot 58 to remove the first and second components 12, 14 that have been pressed together to reject the rejected product in a state where the adhesive bonding result of the adhesive is not satisfactory. Additionally, the control device 24 can also control the alarm device 44 to give a corresponding alarm in a state in which the bonding result of the glue is not satisfactory.

The communication connection of the control device 24 with the various system elements described herein, including but not limited to those already described above, may be achieved through a wireless network and facilitate efficient automated integration of the assembly of the first component 12 to the second component 14 by the specially laid out glue and weighing device 28, optical inspection device 30, lamination device 32, and optional radiographic inspection device 34. The control device 24 functions in: collecting and optionally displaying the weighing result of the weighing module; alarm reminding, reason analysis and classification of bad data; realizing statistical process control, and creating a report according to statistical data; real-time flow control, error prevention, abnormal alarm monitoring and the like; monitoring the current state of the assembly process in real time through a wireless network; and storing the relevant detection data and the image in real time. Thus, the glue assembly system is operated based on a five-major manual for factory quality management.
