Description

Technical Field

[0001] The present invention relates to the technical field of PCB production equipment, and in particular to a docking positioning mechanism. Background Art

[0002] PCBs (printed circuit boards), also known as printed circuit boards (PCBs), are essential components in the electronics industry. They are used in virtually every electronic device, from small electronic watches and calculators to large computers, communications equipment, and military weapon systems. Before being incorporated into electronic products, PCBs must undergo a burning process. This involves placing an integrated circuit chip in a burner and writing a predefined program onto the PCB, enabling the PCB to control the components of the electronic product.

[0003] Before programming, the tray containing the PCBs must be brought to the automatic programming equipment using an automatic tray loading and unloading mechanism. Only after the automatic tray loading and unloading mechanism docks with the automatic programming equipment can the tray be automatically transferred to the equipment. Therefore, precise docking between the automatic tray loading and unloading mechanism and the automatic programming equipment is particularly important. In the existing technology, this docking process requires an operator to manually move the automatic tray loading and unloading mechanism to dock with the automatic programming equipment. Due to the high docking precision requirements, the operator must constantly adjust the position of the automatic tray loading and unloading mechanism and then secure it with multiple threaded fasteners. This is labor-intensive, cumbersome, and has low docking efficiency. Summary of the Invention

[0004] An embodiment of the present invention provides a docking and positioning mechanism for solving the problem in the prior art that when an automatic tray feeding and exiting device is docked with an automatic burning device, an operator manually moves and adjusts the position of the automatic tray feeding and exiting device, resulting in high labor intensity, a cumbersome process and low docking efficiency.

[0005] In an embodiment of the present invention, the docking and positioning structure includes a first docking component and a second docking component, wherein the first docking component and the second docking component are each connected to an external device and are used to dock and fix the two external devices;

[0006] The first docking assembly includes a first mounting member, a guide rail, a first guide structure, and a first fixing structure. The two guide rails are spaced apart and arranged on the first mounting member. The first guide structure and the first fixing structure are both connected to the first mounting member.

[0007] The second docking assembly includes a second mounting assembly and a sliding assembly, a second guide structure and a second fixed structure arranged on the second mounting assembly. The sliding assembly is slidably connected to the guide rail. During the movement of the sliding assembly along the guide rail, the sliding assembly can move from a first height to a second height. The second guide structure can move along the first guide structure to cause the second docking assembly to be laterally offset in the direction of the guide rail until it abuts against the guide rail on one side. When the second docking assembly moves to a predetermined position, the first fixed structure can be connected to the second fixed structure, thereby fixing the relative positions of the first docking assembly and the second docking assembly.

[0008] As a further optional scheme for the docking positioning mechanism, a slide groove is formed on the guide rail, and the lower surface of the slide groove is recessed downward to form a plurality of grooves. The sliding assembly includes a plurality of pulleys, and the pulleys are rotatably connected to the second mounting assembly on both sides of the second mounting assembly. The pulleys are slidably connected to the guide rail through the slide groove. When the pulley is located in the slide groove, the second docking assembly is at a first height, and when the pulley is located in the groove, the second docking assembly is at the second height.

[0009] As a further optional solution for the docking positioning mechanism, a first limiter is fixedly connected to the second mounting assembly. When the second docking assembly is located at the first height, the first limiter is located above the guide rail. When the second docking assembly is located at the second height, the first limiter is crimped against the upper surface of the guide rail.

[0010] As a further optional scheme for the docking positioning mechanism, the first docking assembly also includes a first pressure block, and the second docking assembly also includes a second pressure block. The first pressure block includes a first part and a second part that forms a fixed angle with the first part. The first pressure block is rotatably connected to the guide rail, and the second pressure block is fixedly connected to the second mounting assembly. When the second docking assembly moves to a predetermined position, the first part abuts against the lower part of the second pressure block, and the second part abuts against the upper part of the second pressure block. The second pressure block has a pushing force on the first part. Due to the rotation tendency of the first pressure block, the pushing force can be converted into the pressure of the second part on the second pressure block, thereby pressing the first limit member tightly against the guide rail.

[0011] As a further optional solution of the docking positioning mechanism, a downwardly inclined slope is formed on the end of the sliding groove for introducing the pulley, and the slope is used to guide the pulley to lift upward.

[0012] As a further optional solution of the docking positioning mechanism, the sliding assembly further includes an auxiliary roller, which is rotatably connected to the second mounting assembly, and the rotation axis of the auxiliary roller is vertically arranged, and the auxiliary roller can roll along the guide rail.

[0013] As a further optional solution of the docking positioning mechanism, the auxiliary roller is provided at the end of the second mounting assembly to guide the second mounting assembly into between the two guide rails.

[0014] As a further optional scheme for the docking positioning mechanism, the first guide structure includes a guide block, which is fixedly connected to the first mounting member, and the side surface of the guide block protrudes toward one of the guide rails to form a guide surface. The second guide structure is configured as a guide wheel, and the guide wheel is rotatably connected to the second mounting assembly. When the guide wheel rolls along the guide surface, the guide wheel can drive the second docking assembly to produce a lateral offset under the guidance of the guide surface.

[0015] As a further optional solution of the docking positioning mechanism, the second docking assembly also includes a second limiter, which is fixedly connected to the tail end of the second mounting assembly. When the second docking assembly moves to a predetermined position, the second limiter abuts against the guide rail.

[0016] As a further optional solution for the docking positioning mechanism, the first fixing structure is set as a hook, and the second fixing structure is set as a drawstring quick clip. The hook is connected to one of the first mounting member or the second mounting component, and the drawstring quick clip is connected to the other of the first mounting member and the second mounting component. Connecting the hook with the drawstring quick clip can fix the first docking component and the second docking component.

[0017] Implementing the embodiments of the present invention will have the following beneficial effects:

[0018] The docking positioning mechanism uses a sliding connection between a guide rail and a sliding component to complete the position adjustment of the first docking component and the second docking component in the first direction and the second direction, and realizes the position adjustment of the first docking component and the second docking component in the third direction through the interaction between the first guide structure and the second guide structure. After the position adjustment is completed, the first fixed structure and the second fixed structure are connected, thereby achieving precise alignment of the first positioning component and the second positioning component. The operation is simple, the alignment is accurate, and the docking efficiency is improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] To facilitate understanding of the present invention, the present invention will be described more fully below with reference to the accompanying drawings. The accompanying drawings illustrate preferred embodiments of the present invention. However, the present invention may be implemented in many other forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and comprehensive understanding of the present disclosure.

[0032] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly attached to the other element or there may be an intermediate element. When an element is referred to as being "connected to" another element, it may be directly connected to the other element or there may be an intermediate element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only.

[0033] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this invention pertains. The terms used in this specification of the present invention are for the purpose of describing specific embodiments only and are not intended to limit the present invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0034] An embodiment of the present invention provides a docking and positioning mechanism for solving the problem in the prior art that when an automatic tray feeding and exiting device is docked with an automatic burning device, an operator manually moves and adjusts the position of the automatic tray feeding and exiting device, resulting in high labor intensity, a cumbersome process and low docking efficiency.

[0035] In the embodiment of the present invention, please refer to Figure 1 The docking and positioning mechanism includes a first docking assembly 10 and a second docking assembly 20. Each of the first and second docking assemblies 10 and 20 is connected to an external device for docking and securing the two external devices. In the application scenario primarily targeted by the embodiments of the present invention, the first docking assembly 10 is connected to an automatic burning device 30, and the second docking assembly 20 is connected to an automatic tray loading and unloading device 40. It is readily apparent that the docking and positioning mechanism can also be used for docking and positioning operations involving two other types of devices.

[0036] Please refer to Figures 2 to 5The first docking assembly 10 includes a first mounting member 11, a guide rail 12, a first guide structure 13, and a first fixed structure 14. Two guide rails 12 are spaced apart on the first mounting member 11, and the first guide structure 13 and the first fixed structure 14 are both connected to the first mounting member 11. The second docking assembly 20 includes a second mounting member 21, a sliding assembly 22, a second guide structure 23, and a second fixed structure 24 disposed on the second mounting member 21. The sliding assembly 22 is slidably connected to the guide rail 12. During the movement of the sliding assembly 22 along the guide rail 12, the sliding assembly 22 can move from a first height to a second height. The second guide structure 23 can move along the first guide structure 13, causing the second docking assembly 20 to be laterally offset toward the guide rail 12 until it abuts against the guide rail 12 on one side. When the second docking assembly 20 moves to a predetermined position, the first fixed structure 14 can be connected to the second fixed structure 24, thereby fixing the relative positions of the first docking assembly 10 and the second docking assembly 20.

[0037] It should be noted that the "predetermined position" of the second docking component 20 here refers to the position when the second docking component 20 moves the required distance along the extension direction of the guide rail 12, makes the required lateral offset to the guide rail 12 and is at the second height. This position is determined by the two devices to be docked during the design stage. The movement of the second docking component 20 along the guide rail 12, the offset toward the guide rail 12 and the change in height correspond to three directions in space respectively. In the above three movements, the second docking component 20 completes the positioning of the spatial position, thereby accurately docking with the first docking component 10.

[0038] The docking positioning mechanism uses a sliding connection between the guide rail 12 and the sliding component 22 to complete the position adjustment of the first docking component 10 and the second docking component 20 in the first direction and the second direction, and realizes the position adjustment of the first docking component 10 and the second docking component 20 in the third direction through the interaction between the first guide structure 13 and the second guide structure 23. After the position adjustment is completed, the first fixed structure 14 and the second fixed structure 24 are connected, thereby achieving precise alignment of the first positioning component 10 and the second positioning component 20. The operation is simple, the alignment is accurate, and the docking efficiency is improved.

[0039] In one embodiment, a slide groove 121 is formed on the guide rail 12, and the lower surface of the slide groove 121 is recessed downward to form a plurality of grooves 122. The sliding assembly 22 includes a plurality of pulleys 221. The pulleys 221 are rotatably connected to the second mounting assembly 21 on both sides of the second mounting assembly 21. The pulleys 221 are slidably connected to the guide rail 12 through the slide groove 121. When the pulley 221 is located in the slide groove 121, the second docking assembly 20 is at a first height. When the pulley 221 is located in the groove 122, the second docking assembly 20 is at a second height.

[0040] The advantage of adopting this embodiment is that the resistance to relative movement when the pulley 221 contacts the slide 121 is small, which can reduce the burden on the operator when pushing heavier equipment such as the automatic tray feeding and exiting device 40; the transition between the groove 122 and the slide 121 can adopt a smooth curved surface, and the pulley 221 slides down along the flat curved surface. No device will be generated in this process, thereby avoiding damage to components.

[0041] In a specific embodiment, a first limit member 25 is fixedly connected to the second mounting assembly 21. When the second docking assembly 20 is at a first height, the first limit member 25 is located above the guide rail 12. When the second docking assembly 20 is at the second height, the first limit member 25 is crimped against the upper surface of the guide rail 12.

[0042] The purpose of adopting this embodiment is that, in the case where the first limiting member 25 is not provided, when the pulley 221 falls into the groove 122, the bottom surface of the groove 122 needs to contact the pulley 221 to form a limit. However, the easy rolling characteristic of the pulley 221 may cause the pulley 221 to slip in the groove 122 and cause inaccurate positioning. After the first limiting member 25 is provided, the first limiting member 25 limits the second docking assembly 20 at the second height, and the pulley 221 does not need to contact the bottom surface of the groove 122, thereby avoiding the occurrence of offset.

[0043] In a more specific embodiment, the first docking assembly 10 also includes a first pressure block 15, and the second docking assembly 20 also includes a second pressure block 27. The first pressure block 15 includes a first part 151 and a second part 152 at a fixed angle to the first part 151. The first pressure block 15 is rotatably connected to the guide rail 12, and the second pressure block 27 is fixedly connected to the second mounting assembly 21. When the second docking assembly 20 moves to a predetermined position, the first part 151 abuts against the lower part of the second pressure block 27, and the second part 152 abuts against the upper part of the second pressure block 27. The second pressure block 27 has a pushing force on the first part 151. Due to the rotation tendency of the first pressure block 15, the pushing force can be converted into pressure of the second part 152 on the second pressure block 27, thereby pressing the first limit member 25 tightly against the guide rail 12.

[0044] The advantage of adopting this embodiment is that the first pressure block 15 and the second pressure block 27 are used to drive the first limit member 25 to be pressed against the guide rail 12, thereby increasing the maximum static friction between the first limit member 25 and the guide rail 12 and reducing the possibility of the second docking component 20 sliding relative to the first docking component 10.

[0045] In a further specific embodiment, the first docking assembly 10 further includes a connecting block 16 , which is fixedly connected to the guide rail 12 , and the first pressing block 15 is rotatably connected to the connecting block 16 , thereby achieving connection between the first pressing block 15 and the guide rail 12 .

[0046] In a specific embodiment, a downwardly inclined slope 123 is formed on the end of the sliding groove 121 for introducing the pulley 221, and the inclined surface 123 is used to guide the pulley 221 to lift upward.

[0047] The reason for setting the inclined surface 123 is that the second docking component 20 needs to be lowered from a higher position during the docking process. Therefore, the second docking component 20 needs to be lifted first when it moves into the guide rail 12. Setting the inclined surface 123 can make the lifting process smoother and more labor-saving.

[0048] In a specific embodiment, the sliding assembly 22 further includes an auxiliary roller 222 , which is rotatably connected to the second mounting assembly 21 , and a rotation axis of the auxiliary roller 222 is vertically arranged, and the auxiliary roller 222 can roll along the guide rail 12 .

[0049] In a more specific embodiment, the auxiliary roller 222 is disposed at the end of the second mounting assembly 21 to guide the second mounting assembly 21 into between the two guide rails 12 .

[0050] In a further specific embodiment, the second mounting assembly 21 includes a base plate 211, side plates 212, and a cross bar 213. The two side plates 212 are spaced apart on the base plate 211, the cross bar 213 is connected between the two side plates 212, the pulley 221 and the auxiliary roller 222 are disposed on the side plates 212, and the guide wheel 231 is connected to the cross bar 213.

[0051] In another embodiment, the sliding connection between the guide rail 12 and the sliding assembly 22 can be replaced by a combination of a slide rail and a slider. Specifically, the guide rail 12 is formed with a slide rail, and the sliding assembly 22 includes a slider, which is slidably connected to the slide rail. It should be noted that since the second docking assembly 20 needs to move from a first height to a second height, in this embodiment, the slide rail does not extend along a straight line, but rather should include two parallel parts connected by a smooth track.

[0052] It should be noted that in the above-mentioned embodiments, since the second docking assembly 20 needs to produce lateral offset, the width of the slide groove 121 should be greater than the width of the pulley 221, and space should be reserved in advance on the slide rail to allow the slider to deviate laterally.

[0053] It can be seen that the solution using the slide groove 121 and the pulley 221 makes the movement smoother and the creation of the slide groove 121 and the groove 122 is also relatively simple, so it is the preferred solution in practice.

[0054] In one embodiment, the first guide structure 13 includes a guide block 131 fixedly connected to the first mounting member 11. The side surface of the guide block 131 protrudes toward one of the guide rails 12 to form a guide surface 1311. The second guide structure 23 is configured as a guide wheel 231, which is rotatably connected to the second mounting assembly 21. When the guide wheel 231 rolls along the guide surface 1311, the guide wheel 231 can drive the second docking assembly 20 to generate a lateral deviation under the guidance of the guide surface 1311. The guide surface 1311 can be an inclined surface, a curved surface, or a combination of a curved surface and an inclined surface.

[0055] In another embodiment, the first guide structure 13 and the second guide structure 23 are configured to have inclined surfaces with the same slope. When the second docking assembly 20 moves along the guide rail 12 , the inclined surface of the second guide structure 23 can move along the inclined surface of the first guide structure 13 .

[0056] In one embodiment, the second docking assembly 20 further includes a second limiter 26 , which is fixedly connected to the rear end of the second mounting assembly 21 . When the second docking assembly 20 moves to a predetermined position, the second limiter 26 abuts against the guide rail 12 .

[0057] In one embodiment, the first docking component 10 and the second docking component 20 can be connected by threaded fasteners. In this case, corresponding mounting holes need to be set on the first docking component 10 and the second docking component 20 for installing the threaded fasteners. When the mounting holes set on the first docking component 10 and the second docking component 20 are coaxially aligned, it means that the second docking component 20 has reached the predetermined position. However, this solution is prone to errors when observing the alignment, so a second limit member 26 can be set in conjunction.

[0058] In one embodiment, the first fixing structure 14 is configured as a hook 141, and the second fixing structure 24 is configured as a pull-tab quick clip 241. The hook 141 is connected to one of the first mounting member 11 or the second mounting assembly 21, and the pull-tab quick clip 241 is connected to the other of the first mounting member 11 and the second mounting assembly 21. Connecting the hook 141 and the pull-tab quick clip 241 can secure the first docking assembly 10 and the second docking assembly 20. The pull-tab quick clip 241 is a common type of quick clip in the prior art, and its structure will not be described in detail here.

[0059] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned 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.

[0060] The above-described embodiments merely represent several implementation methods of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the patent for this invention shall be determined by the appended claims.
