Description

TECHNICAL FIELD

[0001] The present application belongs to the field of vehicle lamp production, and particularly relates to a press-fitting device and a vehicle lamp production equipment. BACKGROUND

[0002] In recent years, LED (Light Emitting Diode) has become an important light source selection and is widely used in the lighting field due to its high efficiency, energy saving, low carbon environmental protection and long service life. In the aspect of automobile lighting, LED vehicle lamps are also widely used due to their energy saving, long service life and high brightness. A typical LED vehicle lamp is composed of a core component such as a circuit board, a lamp shell, a cover and a rear cover. Its production process includes a key quality control step: first, the circuit board needs to be precisely fixed inside the lamp shell to ensure the precise matching of the circuit and the heat dissipation structure; then, the circuit board-lamp shell assembly is assembled with the cover and the rear cover to form a complete vehicle lamp product.

[0003] In the last stage of LED vehicle lamp assembly, the circuit board-lamp shell-cover assembly needs to be fixed by a tooling fixture, and then the rear cover is press-fitted on the circuit board-lamp shell-cover assembly through a press-fitting structure. In this process, the feeding and conveying of the circuit board-lamp shell-cover assembly and the rear cover need to be completed respectively, and then the final assembly work is performed. Therefore, multiple independent mechanisms are usually used to complete the feeding, conveying and assembly of the circuit board-lamp shell-cover assembly and the rear cover respectively, resulting in a complex overall equipment structure and a large occupied space. In addition, the tooling fixture is usually fixed and cannot move, and in order to achieve reliable press-fitting, the distance between the tooling fixture and the press-fitting structure is strictly compressed. This compact layout seriously limits the operation area around the tooling fixture, making the first component feeding process difficult and delaying the progress of the entire press-fitting operation.

[0030] Please refer to Figures 1 to 6The embodiment of the present application provides a press-fitting device for connecting a first component 210 and a second component 220, the press-fitting device has a press-fitting station 400 and a feeding station 300, and the press-fitting device comprises a bearing structure 40 for bearing the first component 210, a moving structure 10 for driving the bearing structure 40 to move, a pressing mechanism 20 arranged at the press-fitting station 400, and a feeding structure 30 arranged at intervals with the pressing mechanism 20 and used for providing the second component 220, the bearing structure 40 bears the first component 210 at the feeding station 300, the moving structure 10 drives the bearing structure 40 to move to the press-fitting station 400, the pressing mechanism 20 picks up the second component 220 at the feeding structure 30 and carries the second component 220 above the first component 210, and the pressing mechanism 20 further drives the second component 220 to move downward by a preset distance, so that the second component 220 is assembled to the first component 210.

[0031] In the embodiment of the present application, the first component 210 and the second component 220 are loaded together to form an LED vehicle lamp. Specifically, the LED vehicle lamp is usually assembled by a core assembly including a circuit board, a lamp shell, a cover and a back cover, the circuit board is used for bearing an LED chip, the lamp shell provides heat dissipation and structural support, and the back cover is sealed, wherein the circuit board, the lamp shell and the cover are assembled to form the first component 210, that is, the first component 210 is a circuit board-lamp shell-cover assembly, and the second component 220 is the back cover. Of course, in other possible embodiments, the first component 210 and the second component 220 can also be other structures capable of being assembled together, and the embodiment of the present application does not make a unique limitation to the specific structures of the first component 210 and the second component 220.

[0032] Specifically, the pressing mechanism 20 can drive the second component 220 to lift along a first direction a and can drive the second component 220 to move along a second direction b, wherein the first direction a is a vertical direction, and the second direction b is parallel to a horizontal plane. Therefore, after the pressing mechanism 20 picks up the second component 220 from the feeding structure 30, the pressing mechanism 20 can drive the second component 220 to lift and reciprocate between the bearing structure 40 and the feeding structure 30 along the second direction b, and after driving the second component 220 to be carried above the first component 210, the pressing mechanism 20 can further drive the second component 220 to move downward by a preset distance, so that the second component 220 is assembled to the first component 210.

[0033] It should be noted that the pressing mechanism 20 further drives the second component 220 to move downward by a preset distance, and the preset distance enables the second component 220 to be assembled to a position to be installed on the first component 210. Alternatively, the preset distance can be flexibly set according to different press-fitting requirements, the length of the preset distance cannot be too large, otherwise the second component 220 and the first component 210 will be damaged, and the length of the preset distance cannot be too small, otherwise the second component 220 cannot be stably assembled to the first component 210.

[0034] In the embodiment of the present application, the first component 210 and the second component 220 after the pressing assembly can continue to be conveyed by the moving structure 10 along with the bearing structure 40, and be moved to the next work station, such as a test work station, or be taken away by the downstream equipment of the moving structure 10, such as a mechanical hand.

[0035] In the embodiment of the present application, the feeding work station 300 and the pressing work station 400 are arranged at intervals along the moving direction of the bearing structure 40. In the feeding work station 300, the bearing structure 40 is in a receiving state, at this time, the pressing mechanism 20 and its working area on the pressing work station 400 are separated from each other in the spatial layout, and the feeding work of the first component 210 completely avoids the spatial limitation of the pressing area, and the spacious feeding space greatly reduces the possibility of accidental collision, effectively protecting the bearing structure 40, the first component 210 and the second component 220 from accidental collision damage.

[0036] In use of the pressing assembly of the present application, the bearing structure 40 is driven to move by the moving mechanism, the first component 210 can move along with the bearing structure 40 between the feeding work station 300 and the pressing work station 400, when the bearing structure 40 is on the pressing work station 400, the pressing mechanism 20 picks up the second component 220 at the feeding structure 30 and transports the second component 220 above the first component 210, and drives the second component 220 to move downward by a preset distance, so as to realize the assembly of the second component 220 to the first component 210. In the whole process, the pressing mechanism 20 not only performs the feeding action of the second component 220, but also performs the pressing assembly action of the second component 220, realizes the integration of the feeding function and the pressing assembly function in a single device, makes the structure of the whole pressing assembly more compact, greatly reduces the occupied space of the pressing assembly; and when the bearing structure 40 receives the first component 210 at the feeding work station 300, at this time, the pressing mechanism 20 and its working area on the pressing work station 400 are separated from each other in the spatial layout with the feeding work station 300, the feeding work of the first component 210 completely avoids the spatial limitation of the pressing area, which is beneficial to improve the convenience of feeding of the pressing assembly.

[0037] In addition, by driving the bearing structure 40 to move back and forth between the pressing work station 400 and the feeding work station 300 by the moving structure 10, the first component 210 and the second component 220 can be accurately and stably positioned at the preset position, providing a reliable basis for the subsequent shaping action.

[0038] It can be understood that the embodiment of the present application also includes a control system (not shown in the figure), the moving structure 10, the bearing structure 40, the pressing mechanism 20 and the feeding structure 30 are all connected with the control system, and the control system can control the moving structure 10, the bearing structure 40, the pressing mechanism 20 and the feeding structure 30 to automatically cooperate and operate. Through the automatic cooperation and operation of the moving structure 10, the bearing structure 40, the pressing mechanism 20 and the feeding structure 30, the automation degree is greatly improved, the manual operation is reduced, and the pressing efficiency is greatly improved.

[0039] In some embodiments, as shown in Figure 1 and Figure 2 The pressing mechanism 20 includes a linear moving assembly 21 and a pressing structure 22 slidingly arranged on the linear moving assembly 21, the linear moving assembly 21 is used to drive the pressing structure 22 to move in a three-dimensional space, and the pressing structure 22 is used to pick up the second component 220 and release the second component 220 after the second component 220 is assembled with the first component 210. The linear moving assembly 21. Specifically, the linear moving assembly 21 drives the pressing structure 22 to move up and down along a first direction a, and can drive the pressing structure 22 to move along a second direction b, wherein the first direction a is a vertical direction, and the second direction b is parallel to a horizontal plane. Therefore, the pressing structure 22 can be lifted after picking up the second component 220 from the feeding structure 30, and can move back and forth between the bearing structure 40 and the feeding structure 30 along the second direction b, and can also drive the second component 220 to move downward by a preset distance after driving the second component 220 to be transported above the first component 210, so as to assemble the second component 220 to the first component 210.

[0040] By driving the pressing structure 22 to move in a three-dimensional space through the linear moving assembly 21, the pressing structure 22 can not only perform the feeding action of the second component 220, but also perform the pressing action of the second component 220, which realizes the integration of the feeding function and the pressing function in a single device. Compared with setting two independent devices to respectively perform the feeding action and the pressing action, the physical transfer process of the second component 220 between the two independent devices is saved, and the problems of poor assembly caused by transfer positioning errors, component falling, etc. are fundamentally avoided. The pressing structure 22 directly picks up from the feeding structure 30 and accurately moves to the set position for pressing, the motion path and positioning control are more direct and simplified, the error accumulation link is reduced, the consistency and precision of assembly are significantly improved, and the operation reliability of the equipment is enhanced.

[0041] Optionally, the linear motion assembly 21 includes a translation structure 211 and a lifting structure 212 connected to the translation structure 211. The pressing structure 22 is connected to the lifting structure 212. The translation structure 211 drives the lifting structure 212 and the pressing structure 22 to rise and fall along a first direction a. The translation structure 211 drives the pressing structure 22 to translate along a second direction b. The lifting structure 212 is a lifting cylinder or a lifting motor, and the translation structure 211 is a cylinder or a linear guide 23. By driving the pressing structure 22 to move through the translation structure 211 and the lifting structure 212, the movement stroke of the pressing structure 22 is precisely controllable, avoiding insufficient or excessive pushing distance, and improving the reliability of press-fitting. In addition, by providing the translation structure 211 and the lowering structure, each press-fitting is performed by the mechanical structure according to a preset program, and the moving distance, speed, and force are highly consistent, completely eliminating the uncertainty of manual operation and ensuring the stability of product quality.

[0042] In some embodiments, as Figure 3 As shown, the pressing structure 22 includes a first connecting plate 221 connected to the linear motion assembly 21, a second connecting plate 222 located below the first connecting plate 221, an adsorption member 223 connected to the end of the second connecting plate 222 facing away from the first connecting plate 221, and a buffer member 224 provided between the first connecting plate 221 and the second connecting plate 222. The adsorption member 223 is used to adsorb or release the second member 220, and the buffer member 224 is used to buffer the vibration generated by the second member 220 on the adsorption member 223 when the second member 220 contacts the first member 210. It can be understood that the adsorption member 223 is provided with vacuum adsorption holes so that it can adsorb or release the second member 220.

[0043] When the second member 220 contacts the first member 210 , the buffer 224 can buffer the vibration of the second member 220 on the adsorption member 223 to avoid rigid contact between the second member 220 and the first member 210 , thereby preventing the second member 220 and the first member 210 from being damaged.

[0044] Optionally, the buffer member 224 is a spring. This arrangement ensures appropriate pressure, effectively preventing damage to the second member 220 and the first member 210 due to excessive impact force when the second member 220 and the first member 210 come into contact. Furthermore, the buffer member 224 can accommodate second members 220 and first members 210 of varying sizes, ensuring sufficient cushioning. Furthermore, multiple adsorption members 223 can be provided, specifically two adsorption members 223, spaced apart. The two adsorption members 223 can each adsorb two second members 220, thereby improving press-fitting efficiency.

[0045] Optionally, the pressing mechanism 20 further comprises a guide rail 23 connected to the linear moving assembly 21 and extending along the first direction a, and a sliding block 24 slidingly connected to the guide rail 23, two of the sliding blocks 24 are spaced apart along the first direction a, a first connecting plate 221 and a second connecting plate 222 are respectively connected to the two sliding blocks 24, and the guide rail 23 is used to guide the two sliding blocks 24 to move along the first direction a, thereby guiding the first connecting plate 221, the second connecting plate 222 and the suction accessory 223 to move along the first direction a, so that the movement of the second component 220 is more stable and reliable, and the movement of the second component 220 can be effectively avoided from being deviated.

[0046] Optionally, a receiving tray 60 is arranged below the pressing structure 22, when the placement direction of the second component 220 provided by the feeding structure 30 is incorrect, the pressing structure 22 can drive the second component 220 to move above the receiving tray 60 and be released, so that the receiving tray 60 can recycle the second component 220 with incorrect placement direction.

[0047] In some embodiments, the pressing device further comprises a guide structure 50 connected to the moving structure 10, the guide structure 50 is adjacent to the bearing structure 40, and the guide structure 50 is used to guide the second component 220 to be assembled to a preset position on the first component 210 when the second component 220 moves downward, thereby improving the accuracy of the assembly of the second component 220. It can be understood that the preset position is the mounting position of the second component 220 on the first component 210.

[0048] In some embodiments, as shown in Figure 4 The guide structure 50 comprises a mounting seat 51 connected to the moving structure 10 and a guide plate 52 connected to the mounting seat 51, the guide plate 52 extends above the first component 210, the guide plate 52 is provided with a guide hole 521 corresponding to the preset position, and the second component 220 passes through the guide hole 521 and is assembled to the preset position in the process of moving downward. By setting the guide plate 52 and the guide hole 521 for guiding, when the pressing structure drives the second component 220 to move downward, the end thereof must first align and pass through the guide hole 521, which is equivalent to a position correction before finally connecting with the first component 210, avoiding poor assembly, and the guide hole 521 is provided with a chamfer or a smooth transition surface on the inner wall thereof, the second component 220 is gently guided and centered by the inner wall of the guide hole 521 before contacting the first component 210, and gradually enters the correct path, thereby greatly reducing the impact force.

[0049] In some embodiments, the mounting base 51 comprises a lifting driving member 511 connected to the moving structure 10 and a sliding driving member 512 connected to the lifting driving member 511, and the guide plate 52 is connected to the sliding driving member 512, the lifting driving member 511 is configured to drive the sliding driving member 512 to lift along the first direction a, and the sliding driving member 512 is configured to drive the guide plate 52 to move along the second direction b, and the first direction a is perpendicular to the second direction b. By driving the sliding driving member 512 to lift along the first direction a by the lifting driving member 511, the guide plate 52 is lifted along the first direction a synchronously, so that the distance between the guide plate 52 and the first component 210 can be adjusted flexibly, and the first component 210 with different height sizes can be adapted, and the applicability is improved, and the guide plate 52 is driven by the sliding driving member 512 to move along the second direction b, so that the guide plate 52 can be moved to the preset position accurately, and the reliability of the guide is improved.

[0050] In some embodiments, the feeding structure 30 comprises a vibrating disc 31, a material channel 32, and a material bin 33 for storing the second components 220, the material channel 32 has a feeding end connected to the vibrating disc 31 and a discharging end connected to the pressing mechanism 20, the vibrating disc 31 receives a plurality of second components 220 from the material bin 33 and vibrates the plurality of second components 220, so that each second component 220 is sequentially moved to the feeding end and then moved to the discharging end. By vibrating and sorting the plurality of second components 220 by the vibrating disc 31, the plurality of second components 220 can be automatically separated and fed, which is beneficial to improve the feeding efficiency of the second components 220.

[0051] In some embodiments, the moving structure 10 comprises a rack 11, a rotating disc 12 rotatably connected to the rack 11, and a rotating driving member 13 arranged on the rack 11 and connected to the rotating disc 12, the pressing station 400 and the feeding station 300 are arranged along the circumference of the rotating disc 12, the carrying structure 40 is connected to the edge of the rotating disc 12, and the rotating driving member 13 is configured to drive the rotating disc 12 to rotate so that the carrying structure 40 moves between the pressing station 400 and the feeding station 300. By driving the carrying structure 40 to rotate by the rotating disc 12, compared with the linear layout of the carrying structure 40 transmitted along a straight line, the occupying space of the pressing and assembling device is smaller and the structure is more compact by the transmission mode of the rotating disc 12, which is beneficial to reduce the occupying space of the pressing and assembling device.

[0052] Optionally, a plurality of carrying structures 40 can be arranged on the rotating disc 12, and the rotating disc 12 drives each carrying structure 40 to move to the feeding station 300 and the pressing station 400 in sequence, and the movement of the entire system only needs one rotating driving member 13 to drive all the carrying structures 40 to be conveyed, which greatly simplifies the driving and control system, and does not need a complex linear conveying belt system, a multi-axis mechanical arm, or a large number of independent push cylinders to realize the transfer of the carrying structures 40 between the pressing station 400 and the feeding station 300.

[0053] Optionally, the rotating drive 13 can include a stepper motor, a speed reducer, and an indexing structure. The stepper motor provides precise angle control, and controls the rotation angle and speed by receiving pulse signals. The speed reducer is usually a planetary reducer or a worm reducer, which reduces the output speed of the motor while greatly increasing the output torque to meet the needs of driving the large inertia rotating disc 12 and improve system rigidity and reduce vibration. The indexing mechanism is the key to precise indexing positioning, and the indexing mechanism can specifically adopt a cam divider. The cam divider uses a conjugate cam structure inside to convert the continuous rotation of the motor into intermittent precise indexing motion of the rotating disc 12, which has extremely high positioning accuracy and repeat positioning accuracy, strong carrying capacity, good rigidity, smooth operation, and long service life. It is suitable for high-speed, high-precision, and heavy-load applications.

[0054] Of course, in other possible embodiments, the moving structure 10 can be a belt transmission structure. Due to tensioning, the belt transmission structure generates a compression force at the contact part of the belt and the pulley. When the main pulley is running, the belt is driven by friction. Because the belt drive works by friction, it can effectively moderate the impact of the load and run smoothly and quietly.

[0055] In some embodiments, as shown in Figure 6 The carrier structure 40 includes a placement seat 41 for carrying the first component 210 and a limiting block 42 arranged on the placement seat 41. The limiting block 42 is arranged in multiple directions along the circumference of the placement seat 41, and the multiple limiting blocks 42 form a limiting space 43 for limiting the first component 210. Therefore, the multiple limiting blocks 42 limit the first component 210 from multiple directions, thereby improving the limiting effect of the first component 210, stabilizing the position of the first component 210 during the press-fitting process, and further improving the stability and accuracy of the press-fitting.

[0056] In some embodiments, the shape of the limiting space 43 is adapted to the outer contour of the first component 210, that is, the multiple limiting blocks 42 form a contoured cavity that accommodates the first component 210. Since the contoured cavity highly matches the outer contour of the first component 210, it provides a maximum contact area and eliminates the possibility of slight shaking or rotational freedom of the first component 210 during positioning. Multiple complex curved surfaces simultaneously contact and constrain, which can accurately and uniquely fix the first component 210 at the intended position and direction.

[0057] In addition, the operator only needs to place the first component 210 into the shape-matched contoured cavity, and it will automatically and quickly fall into the only correct position. There is no need to adjust, align multiple positioning pins or reference surfaces, which greatly reduces the clamping time and reduces the operation difficulty and error rate.

[0058] In some embodiments, the limiting blocks 42 have abutting surfaces 421 abutting against the first member 210, the abutting surfaces 421 are adapted to the shape of the outer surface of the first member 210, and the plurality of abutting surfaces 421 are simultaneously contacted and constrained, so that the first member 210 can be accurately and uniquely fixed at the expected position and direction.

[0059] The application also provides a vehicle lamp production device, which comprises the pressing device, and the specific structure of the pressing device is referred to the above-mentioned embodiments. Since the vehicle lamp production device adopts all the technical solutions of the above-mentioned embodiments, it also has all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be repeated here.

[0060] In summary, when the pressing device is in use, the moving mechanism is arranged to drive the bearing structure 40 to move, and the first member 210 can be synchronously moved with the bearing structure 40 between the feeding station 300 and the pressing station 400. When the bearing structure 40 is at the pressing station 400, the pressing mechanism 20 picks up the second member 220 at the feeding structure 30 and transports the second member 220 above the first member 210, and drives the second member 220 to move downward by a preset distance, so as to realize the assembly of the second member 220 to the first member 210. During the whole process, the pressing mechanism 20 not only performs the feeding action of the second member 220, but also performs the pressing action of the second member 220, so as to integrate the feeding function and the pressing function in a single device, so that the structure of the whole pressing device is more compact, and the occupied space of the pressing device is greatly reduced. When the bearing structure 40 receives the first member 210 at the feeding station 300, the pressing mechanism 20 and its working area at the pressing station 400 are separated from the feeding station 300 in spatial layout, and the feeding work of the first member 210 completely avoids the space limitation of the pressing area, which is beneficial to improve the convenience of feeding of the pressing device.

[0061] The above is only an optional embodiment of the application and is not used to limit the application. The application can have various changes and modifications for those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the application shall be included in the scope of claims of the application.
