Description

Technical Field

[0001] This utility model relates to the field of automated equipment manufacturing technology, and in particular to a pressure-holding fixture docking and conveying line. Background Technology

[0002] In the production of electronic components, precision mechanical parts, and other products, pressure holding is a crucial step in ensuring product assembly quality, and pressure holding fixtures play a key role in this process.

[0003] To meet the demands of automated production, existing designs typically employ two independent conveyor lines, one for conveying the fixture body and the other for conveying the pressure-holding cover.

[0004] From a spatial perspective, this type of design with two independent conveyor lines has obvious shortcomings: each conveyor line occupies an independent area, which not only requires more design space, but also inevitably leads to the dispersion of the conveying paths of the fixture body and the pressure-holding cover plate, which increases the spatial span when the two are connected, making it impossible to achieve compact spatial integration and seriously affecting the space utilization rate of the production line.

[0005] In terms of motion coordination, the drive systems and operating parameters of the two conveyor lines differ, and during long-term operation, time deviations in the arrival times of the fixture body and the pressure-holding cover at the working position are unavoidable. Therefore, additional high-precision sensors and complex control systems are required to coordinate the motion processes of the two conveyor lines. This not only significantly increases hardware and system maintenance costs but also easily leads to inconsistent conveying rhythms between the fixture body and the pressure-holding cover during actual operation, thus severely reducing conveying efficiency.

[0006] In summary, technical personnel are urgently needed to solve the above problems. Utility Model Content

[0007] The purpose of this invention is to provide a pressure-holding fixture docking conveyor line, which aims to solve the problems of large space occupation, large docking span, low efficiency, and time deviation caused by different drives in the existing design of two independent conveyor lines.

[0008] This utility model relates to a pressure-holding fixture docking and conveying line, comprising:

[0009] The pressure-holding fixture consists of a fixture body and a pressure-holding cover plate that cooperate with each other; the fixture body is provided with a sinking groove for accommodating the workpiece to be processed; when the pressure-holding cover plate is closed on the fixture body, the workpiece placed in the sinking groove is subjected to continuous pressure.

[0010] Belt conveyors are used to carry and transport fixture bodies and pressure-holding cover plates in their respective independent states;

[0011] The blocking component is installed at the stopping station of the belt conveyor; when the pressure-holding cover plate is conveyed to the stopping station, the blocking component blocks the pressure-holding cover plate and achieves positioning.

[0012] The lifting mechanism is installed at the lifting station of the belt conveyor, and the lifting station and the stopping station are distributed at intervals along the conveying direction. The lifting mechanism is used to lift the fixture body and remove it from the belt conveyor when the fixture body is conveyed to the lifting station.

[0013] The handling robotic arm is set on one side of the belt conveyor, and its working range covers both the stopping station and the lifting station.

[0014] After the workpiece to be processed is placed in the sinking groove, the handling robot arm grabs the pressure holding cover plate located at the blocking station and moves it to the lifting station, and finally covers it onto the fixture body to complete the docking.

[0015] As a further improvement to the technical solution disclosed in this utility model, the pressure-holding fixture docking conveyor line also includes a first position sensor; the first position sensor is located at the lifting station and is electrically connected to the lifting mechanism; when the first position sensor detects that the fixture body is conveyed to the lifting station, it sends an electrical signal to the lifting mechanism to trigger the lifting mechanism to lift the fixture body.

[0016] As a further improvement to the technical solution disclosed in this utility model, the pressure-holding fixture docking conveyor line also includes a second position sensor; the second position sensor is located at the stop station and is electrically connected to the handling robot arm; when the second position sensor detects that the pressure-holding cover plate is conveyed to the stop station and abuts against the blocking component, and the fixture body is lifted by the lifting mechanism, the handling robot arm receives the electrical signal and performs a gripping operation on the pressure-holding cover plate.

[0017] As a further improvement to the technical solution disclosed in this utility model, the pressure holding fixture docking conveyor line also includes a guide component; the guide component is located upstream of the stop station along the conveying direction of the belt conveyor, and is used to guide the pressure holding cover plate during the conveying process to the stop station, so that the pressure holding cover plate is accurately conveyed to the position where it abuts against the blocking component, which is conducive to the handling robot arm to grasp it.

[0018] As a further improvement to the technical solution disclosed in this utility model, the guide assembly includes a symmetrically arranged front guide plate and a rear guide plate, which are respectively installed on the front and rear side beams of the belt conveyor; the outward inclined sections of the front guide plate and the rear guide plate together form an outwardly expanding flared mouth to initially guide and correct the pressure-holding cover plate, and the distance between the straight sections of the two is adapted to the width of the pressure-holding cover plate.

[0019] As a further improvement to the technical solution disclosed in this utility model, the lifting mechanism includes a base plate, a lifting plate, a cylinder, and at least two sets of guide sleeve assemblies; the base plate is mounted on a belt conveyor; the cylinder is used to drive the lifting plate to perform lifting and lowering movements in the height direction and is fixed on the base plate; the guide sleeve assembly is used to guide the lifting and lowering movements of the lifting plate and is disposed between the base plate and the lifting plate.

[0023] 2) The blocking components of the stopping station cooperate with the lifting mechanism of the lifting station to accurately position the pressure holding cover and the fixture body respectively. Combined with the automated operation of the handling robot arm, there is no need to configure an additional complex coordination control system and high-precision sensors.

Detailed Implementation

[0030] The present invention will be further described in detail below with reference to specific embodiments. Figure 1 A three-dimensional schematic diagram of the pressure-holding fixture docking and conveying line disclosed in this utility model is shown. It can be seen that it is mainly composed of several parts, including a pressure-holding fixture 1, a belt conveyor 2, a blocking component 3, a lifting mechanism 4, and a handling robotic arm (not shown in the figure).

[0031] The pressure-holding fixture 1 plays a crucial role in the gluing process of electronic components, precision mechanical parts, and other products. It consists of a fixture body 11 and a pressure-holding cover plate 12 that cooperate with each other. Figure 2 As shown, the recessed groove 111 of the fixture body 11 is used to place the workpiece after applying adhesive, providing it with a stable placement space. When the pressure-holding cover 12 is closed on the fixture body 11, continuous pressure is applied to the workpiece, so that the adhesive fully adheres to the contact surface of the workpiece under pressure, thereby avoiding problems such as air bubbles and incomplete adhesion, and ensuring the connection strength after the adhesive has cured.

[0032] The belt conveyor 2 bears the function of carrying and transporting, and the independent fixture body 11 and the pressure cover plate 12 are transported alternately on it at preset intervals to ensure that the two do not contact or interfere with each other during the transport process.

[0033] The blocking component 3 is installed at the stopping station of the belt conveyor 2. When the pressure-holding cover plate 12 is conveyed to the stopping station, the blocking component 3 will block the pressure-holding cover plate 12, thereby achieving precise positioning of it.

[0034] The lifting mechanism 4 is installed at the lifting station of the belt conveyor 2, and the lifting station and the stopping station are distributed at intervals along the conveying direction. When the fixture body 11 is conveyed to the lifting station, the lifting mechanism 4 will lift the fixture body 11 and make it detach from the belt conveyor 2.

[0035] The handling robotic arm is located in front of the belt conveyor 2, and its working range covers both the blocking station and the lifting station.

[0036] The workflow of the pressure-holding fixture docking conveyor line is as follows:

[0037] First, the belt conveyor 2 starts running, synchronously conveying the fixture body 11 and the pressure-holding cover plate 12, which are in an independent state, along the preset conveying direction. At this time, the sinking groove 111 of the fixture body 11 is in an empty state, waiting to place the glued workpiece to be processed;

[0038] When the pressure-holding cover plate 12 is conveyed to the stop station by the belt conveyor 2, the blocking component 3 installed at the station immediately acts to block the pressure-holding cover plate 12, stopping its movement and achieving precise positioning, thus preparing for subsequent gripping operations.

[0039] Meanwhile, the fixture body 11 continues to be conveyed forward by the belt conveyor 2 until it reaches the lifting station. At this time, the lifting mechanism 4 of the lifting station is activated, lifting the fixture body 11 upward and detaching it from the conveying surface of the belt conveyor 2, ensuring that the fixture body 11 remains in a stable docking state;

[0040] Subsequently, the external feeding device (or manual operation) accurately places the glued workpiece to be processed into the sinking groove 111;

[0041] After the workpiece is placed, the handling robot arm starts working. First, it grabs the pressure holding cover plate 12 in the blocking position and moves the pressure holding cover plate 12 to the lifting position according to the preset path. Then, the handling robot arm controls the pressure holding cover plate 12 to slowly close onto the jig body 11 in the lifting state, so that the pressure holding cover plate 12 applies continuous pressure to the workpiece in the sinking groove 111, and completes the docking operation of the pressure holding jig.

[0042] After docking is completed, the lifting mechanism 4 is reset and the fixture body 11 with the pressure-holding cover plate 12 is placed back into the belt conveyor 2, which then transports it to the next process. At the same time, the blocking member 3 performs a downward movement to release the obstruction.

[0043] In practical applications, the pressure-holding fixture docking conveyor line disclosed in this utility model has achieved at least the following beneficial technical effects:

[0044] 1) The fixture body 11 and the pressure-holding cover plate 12 are conveyed along a preset path on the same belt conveyor 2, which greatly shortens the spatial span when the two are connected, which is conducive to achieving a compact space integration design and significantly improves the space utilization rate of the production line. Furthermore, the drive system and operating parameters of the same belt conveyor 2 are unified, avoiding the time deviation problem caused by parameter differences and long-term wear in traditional designs.

[0045] 2) The blocking component 3 of the blocking station and the lifting mechanism 4 of the lifting station cooperate with each other to accurately position the pressure holding cover plate 12 and the fixture body 11 respectively. Combined with the automated operation of the handling robot arm, without the need for additional complex coordination control system and high-precision sensors, the consistency of the conveying rhythm of the fixture body 11 and the pressure holding cover plate 12 is ensured, which ultimately helps to improve the docking efficiency of the pressure holding fixture 1.

[0046] Depend on Figure 1 As clearly shown in the diagram, a first position sensor 5 is installed at the lifting station, which is electrically connected to the lifting mechanism 4. When the first position sensor 5 detects that the fixture body 11 has been transported to the lifting station, it sends an electrical signal to the lifting mechanism 4, ensuring that the fixture body 11 is lifted immediately upon arrival at the lifting station, preventing it from deviating from the preset position due to delay, and ensuring that the fixture body 11 remains in a stable docking state. The first position sensor 5 uses high-precision photoelectric sensing technology, which can sensitively capture the edge features or specific marks of the fixture body 11, ensuring the accuracy of detection and avoiding malfunctions of the lifting mechanism 4 due to misjudgment.

[0047] Similarly, Figure 1 As shown, a second position sensor 6 is installed at the stop station and is electrically connected to the handling robot arm. The second position sensor 6 employs the same high-precision detection technology as the first position sensor 5 to accurately identify whether the pressure-holding cover 12 has been delivered to the stop station. Furthermore, the second position sensor 6 is linked with the first position sensor 5, confirming through signal interaction whether the fixture body 11 has been lifted by the lifting mechanism 4. When both conditions are met—the pressure-holding cover 12 is in position and the fixture body 11 is lifted—the second position sensor 6 immediately sends an electrical signal to the handling robot arm. This effectively avoids robot arm malfunctions caused by misjudgment of a single signal, ensuring the accuracy and safety of the gripping action.

[0048] like Figure 1As shown, the pressure-holding fixture docking conveyor line is also equipped with a guide assembly 7. The guide assembly 7 is located upstream of the stop station along the conveying direction of the belt conveyor 2, and it consists of a symmetrically distributed front guide plate 71 and a rear guide plate 72. A guide channel with a gradually changing width is formed between the front guide plate 71 and the rear guide plate 72. The end near the upstream is shaped like a "trumpet mouth" and its width is slightly larger than the width of the pressure-holding cover plate 12. The width of the end near the stop station is adapted to the width of the pressure-holding cover plate 12. During the conveying of the pressure-holding cover 12 to the blocking station, the front guide plate 71 and the rear guide plate 72 effectively guide it. When the pressure-holding cover 12 deviates slightly on the belt conveyor 2, its position will be corrected by the front guide plate 71 and the rear guide plate 72 on both sides, so that it is accurately conveyed to the position that abuts against the blocking member 3. This ensures that the pressure-holding cover 12 can stop at the blocking station in a uniform posture every time, which lays a good foundation for the subsequent gripping operation of the handling robot arm, greatly reduces the positioning difficulty of the robot arm during gripping, and improves the gripping success rate.

[0049] like Figure 3 , Figure 4 As shown, the lifting mechanism 4 mainly consists of a base plate 41, a lifting plate 42, a cylinder 43, and at least two sets of guide sleeve assemblies 44. The base plate 41, using the belt conveyor 2 as its mounting base, provides stable support for the entire lifting mechanism 4, ensuring no shaking or displacement occurs during the lifting process. The cylinder 42, as a power source, drives the lifting plate 42 to perform lifting movements along the height direction; it is detachably fixed to the base plate 41. The guide sleeve assembly 44 guides the lifting movement of the lifting plate 42 and is located between the base plate 41 and the lifting plate 42. The guide sleeve assembly 44 consists of a guide post and a guide sleeve. The guide post is fixed to the lifting plate 42, and the guide sleeve is embedded in the base plate 41. The two slide together to ensure that the lifting plate 42 always moves along the height direction during the lifting process, avoiding tilting or deviation, thereby ensuring that the fixture body maintains a stable posture after being lifted.

[0050] Finally, it should also be noted that, similarly... Figure 3 , Figure 4 As shown, two locating pins 45 are located on the top wall of the lifting plate 42, and the fixture body 11 has locating holes 112 that are adapted to the locating pins 45. The top of the locating pin 45 has a guide cone surface. During the process of the lifting plate 42 approaching the fixture body 11, even if there is a slight positional deviation in the fixture body 11, each locating pin 45 can smoothly and gradually penetrate into the corresponding locating hole 112 under the guidance of the guide cone surface. After the lifting plate 42 lifts the fixture body 11, the locating pins 45 and the locating holes 112 are precisely engaged, forming a stable constraint on the fixture body in the horizontal direction, thereby further realizing the precise positioning of the fixture body 11 and preventing it from shifting or shaking during the subsequent workpiece placement and pressure-holding cover closing process.

[0051] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
