Abstract
Description
Technical Field
[0001] This utility model relates to the field of PCB board processing technology, and in particular to a hanger horizontal movement device and PCB board processing equipment. Background Technology
[0002] In PCB manufacturing equipment, a lateral movement device is typically used to move the PCB clamped on the PCB back and forth laterally, allowing the PCB to be moved to a designated position for processing. A common lateral movement device consists of a frame and a traversing crane on which the PCB is mounted. Both the frame and the traversing crane are equipped with slide rails and sliders, which are slidably connected to each other to allow the traversing crane to slide relative to the frame.
[0003] In existing technology, both the slide rail and the slider are fixed to the frame and the traverse crane using screws. If the PCB board shakes during movement, causing the traverse crane connected to the bracket to shift relative to the frame, this will lead to a misalignment between the slider and the slide rail, resulting in them jamming together and preventing the traverse crane from moving relative to the frame. Therefore, there is an urgent need for a bracket traverse device that can provide smooth and stable movement to ensure that the traverse crane can move reliably relative to the frame.
[0004] It should be noted that the above content is only used to help understand the technical solution of this utility model, and does not represent an admission that the above content is prior art. Utility Model Content
[0005] The main purpose of this utility model is to propose a hanger lateral movement device and PCB board processing equipment, which aims to provide a smooth and stable movement effect to ensure that the lateral movement crane can reliably move relative to the frame.
[0006] To achieve the above objectives, this utility model proposes a hanger lateral movement device, which includes a frame and a lateral movement trolley on which the hanger is mounted. The frame is fixedly connected to a slide rail, and the lateral movement trolley is equipped with a slider via a connecting assembly. The slider is slidably connected to the slide rail. The connecting assembly includes a first connector and a second connector. The first connector has a concave structure, and the second connector has a convex structure, so that the first connector and the second connector are connected to each other in a concave-convex fit. Furthermore, there is a preset gap between the concave structure and the convex structure along the sliding direction of the slider.
[0007] In one embodiment, the first connecting member is fixedly connected to the transverse crane, and the second connecting member is fixedly connected to the slider; or, the first connecting member is fixedly connected to the slider, and the second connecting member is fixedly connected to the transverse crane.
[0008] In one embodiment, the frame includes two parallel slide rails, which are respectively located on opposite sides of the transverse trolley. The transverse trolley is mounted on the two slide rails. The two slide rails are arranged at different heights. The slider corresponding to the lower slide rail is connected to the transverse trolley via the connecting component, and the slider corresponding to the higher slide rail is fixedly connected to the transverse trolley.
[0009] In one embodiment, the lateral movement device further includes a lateral movement drive device for driving the lateral movement crane to slide relative to the frame along the slide rail.
[0010] In one embodiment, a plurality of positioning sensors are installed on the frame along the sliding path of the traverse crane, and the positioning sensors are electrically connected to the traverse drive device.
[0011] In one embodiment, the transverse drive device includes a rotary motor and a gear mounted on the transverse crane, and a rack mounted on the frame, wherein the length direction of the rack is parallel to the length direction of the slide rail; the gear meshes with the rack, and the rotary motor drives the gear to rotate.
[0012] In one embodiment, the rotary motor is electrically connected to an external power source via a power cord; the traverse crane is equipped with a tank chain for wrapping the power cord.
[0013] In one embodiment, the slide rail is disposed in an oil receiving groove, which is used to hold the lubricating oil between the slide rail and the slider.
[0014] In one embodiment, the traverse crane is connected to the hanger via a connecting rod, wherein the connection between the connecting rod and the traverse crane is provided with a reinforcing rib.
[0015] To achieve the above objectives, this utility model proposes a PCB board processing equipment, which includes a hanger transverse movement device as described in any of the above claims.
[0016] The technical solution of this utility model involves setting a connecting component between the slider and the transverse trolley. This connecting component includes a first connector and a second connector, each having a concave and a convex structure, respectively. The first and second connectors are connected via a concave-convex fit, allowing the transverse trolley and slider to move laterally in a mutually responsive manner. Simultaneously, a preset gap exists between the concave and convex structures along the sliding direction of the slider, meaning the first connector can move slightly relative to the second connector, thus providing a certain adjustment space between the transverse trolley and the slider. Therefore, when the PCB board shakes during movement, causing the transverse trolley connected to the bracket to shift relative to the frame, the relative position of the transverse trolley and slider can be adjusted using this adjustment space. The slider will not shift with the transverse trolley, preventing misalignment and jamming between the slider and the slide rail. The transverse trolley can still move relative to the frame, achieving a smooth and stable movement effect to ensure reliable movement of the transverse trolley relative to the frame.

[0026] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, what is described is only a part of the embodiments of this utility model, and not all of the embodiments.

[0027] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.
[0028] Furthermore, it should be noted that the descriptions involving "first," "second," etc., in this utility model are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. If the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this utility model.
[0029] In the existing technology, both the slide rail and the slider are fixed to the frame and the traverse crane with screws. If the PCB board shakes during the movement, causing the traverse crane connected to the bracket to shift relative to the frame, it will cause the slider and the slide rail to shift and jam, making the traverse crane unable to move relative to the frame.
[0030] To solve the above-mentioned technical problems, this utility model proposes a hanger horizontal movement device and a PCB board processing equipment.
[0031] Please see the appendix Figure 1 and appendix Figure 4 In one embodiment of this utility model, the horizontal movement device includes a frame 1 and a horizontal moving trolley 2 on which a hanging bracket (not shown in the figure) is installed. The frame 1 is fixedly connected to a slide rail 3, and the horizontal moving trolley 2 is equipped with a slider 4 through a connecting assembly 5. The slider 4 is slidably connected to the slide rail 3. The connecting assembly 5 includes a first connecting member 501 and a second connecting member 502. The first connecting member 501 has a concave structure, and the second connecting member 502 has a convex structure, so that the first connecting member 501 and the second connecting member 502 are connected to each other in a concave-convex fit manner, and there is a preset gap between the concave structure and the convex structure along the sliding direction of the slider 4.
[0032] The technical solution of this utility model involves setting a connecting component 5 between the slider 4 and the transverse crane 2. The connecting component 5 includes a first connecting member 501 and a second connecting member 502, which respectively have a concave structure and a convex structure, allowing them to be connected in a concave-convex fit. This enables the transverse crane 2 and the slider 4 to move laterally by mutual mutual drive. Simultaneously, a preset gap exists between the concave and convex structures along the sliding direction of the slider 4, meaning that the first connecting member 501 can move slightly relative to the second connecting member 502. The relative movement between the traverse crane 2 and the slider 4 creates a certain adjustment space. Therefore, when the PCB board wobbles during movement, causing the traverse crane 2, connected to the hanger, to shift relative to the frame 1, the relative position of the traverse crane 2 and the slider 4 can be adjusted using this adjustment space. That is, the slider 4 will not shift with the traverse crane 2, preventing the slider 4 from shifting and jamming with the slide rail 3. The traverse crane 2 can still move relative to the frame 1, thus providing a smooth and stable movement effect to ensure that the traverse crane 2 can reliably move relative to the frame 1.
[0033] Specifically, the first connecting member 501 is fixedly connected to the transverse crane 2, and the second connecting member 502 is fixedly connected to the slider 4; or, the first connecting member 501 is fixedly connected to the slider 4, and the second connecting member 502 is fixedly connected to the transverse crane 2; this application does not impose any specific limitations on this.
[0034] As a preferred embodiment of the above embodiments, refer to the appendix. Figure 1The frame 1 includes two parallel slide rails 3, which are respectively positioned on opposite sides of the transverse trolley 2. The transverse trolley 2 is mounted on the two slide rails 3. The two slide rails 3 are arranged at different heights. The slider 4 corresponding to the lower slide rail 3 is connected to the transverse trolley 2 via a connecting component 5, while the slider 4 corresponding to the higher slide rail 3 is fixedly connected to the transverse trolley 2. This arrangement, with the slide rails 3 designed to be arranged in two parallel rows and the transverse trolley 2 mounted on them, utilizes the two slide rails 3 to support opposite sides of the transverse trolley 2, thereby improving the stability of the transverse trolley 2 when sliding relative to the frame 1. Meanwhile, since the position adjustment between the transverse crane 2 and the slider 4 can be satisfied by setting a connecting component 5 between the slider 4 corresponding to one of the slide rails 3 and the transverse crane 2, the setting of the connecting component 5 will inevitably occupy the vertical space between the slide rail 3 and the transverse crane 2; therefore, in this embodiment, the two slide rails 3 are designed to be set at different heights, and the connecting component 5 is set between the slider 4 corresponding to the slide rail 3 at the lower position and the transverse crane 2; it can be understood that the height difference between the two slide rails 3 corresponds exactly to the height of the connecting component 5, so that the transverse crane 2 is finally placed horizontally on the two slide rails 3.
[0035] Further, see attached document. Figure 3 The slide rail 3 is positioned within the oil receiving groove 6, which serves to collect the lubricating oil between the slide rail 3 and the slider 4 (not shown in the attached diagram). This arrangement reduces friction between the slide rail 3 and the slider 4, thereby improving the smoothness of the slider 4's movement relative to the slide rail 3. Simultaneously, placing the slide rail 3 within the oil receiving groove 6 prevents the lubricating oil from dripping directly onto the ground and causing environmental pollution.
[0036] As a preferred embodiment of the above, the hanger traversing device further includes a traversing drive device 7, which drives the traversing crane 2 to slide along the slide rail 3 relative to the frame 1. This configuration, using the traversing drive device 7 as a power source to drive the traversing crane 2 to slide along the slide rail 3 relative to the frame 1, improves the automation level of the hanger traversing device.
[0037] There are many specific structures for the transverse drive device 7. In this embodiment, please refer to the attached diagram. Figure 2The transverse drive device 7 includes a rotary motor 701 and a gear 702 mounted on the transverse crane 2, and a rack 703 mounted on the frame 1. The length direction of the rack 703 is parallel to the length direction of the slide rail 3. The gear 702 is meshed with the rack 703, and the rotary motor 701 drives the gear 702 to rotate. With this configuration, the rotary motor 701 acts as a power source to drive the gear 702 to rotate. Since the gear 702 is meshed with the rack 703, when the gear 702 rotates, it drives the transverse crane 2 to slide along the slide rail 3, thus achieving the sliding motion of the transverse crane 2 relative to the frame 1. The structure is simple and highly practical.
[0038] Specifically, a plurality of parallel first angle steels 101 are fixedly installed above the slide rail 3, with the length direction of the plurality of first angle steels 101 perpendicular to the length direction of the slide rail 3; a second angle steel 102 is installed below the plurality of first angle steels 101, wherein the length direction of the second angle steel 102 is parallel to the length direction of the slide rail 3; then the rack 703 is installed on the second angle steel 102 to complete the installation of the rack 703.
[0039] Furthermore, the rotary motor 701 is electrically connected to an external power source via a power cord (not shown in the attached diagram); a tank chain (not shown in the attached diagram) is installed on the transverse crane 2 to wrap the power cord. This arrangement serves to protect the power cord on the motor, preventing it from being torn or worn during the reciprocating motion of the transverse crane 2; specifically, one end of the tank chain is fixed to the transverse crane 2, and the other end is connected to an external power supply device.
[0040] Furthermore, see the attached document. Figure 3 Several positioning sensors 8 are installed on the frame 1 along the sliding path of the traverse crane 2. The positioning sensors 8 are electrically connected to the traverse drive device 7. With this configuration, the positioning sensors 8 are used to detect the sliding position of the traverse crane 2 in real time. When the positioning sensors 8 detect that the traverse crane 2 has slid to a designated position, they drive the traverse drive device 7 to stop operation so that the traverse crane 2 stops at the designated position.
[0041] As a preferred embodiment of the above embodiments, refer to the appendix. Figure 5 The horizontal traverse crane 2 is connected to the hanger via a connecting rod 9, and a reinforcing rib 901 is provided at the connection between the connecting rod 9 and the horizontal traverse crane 2. This design, with the reinforcing rib 901, improves the connection strength between the connecting rod 9 and the horizontal traverse crane 2, resulting in a simple and practical structure.
[0042] This embodiment also discloses a PCB board processing equipment, including the rack traversing device of any of the above embodiments. The specific structure of the rack traversing device can be referred to the above embodiments. Since this PCB board processing equipment adopts all the technical solutions of all the above embodiments, it possesses at least all the beneficial effects brought about by the technical solutions of the above embodiments, and will not be elaborated further here.
[0043] It should be noted that the other contents of the hanging bracket transverse movement device and PCB board processing equipment disclosed in this utility model are existing technologies and will not be described in detail here.
[0044] The above are merely optional embodiments of this utility model and do not limit the patent scope of this utility model. Any application of this utility model directly or indirectly in other related technical fields is included within the patent protection scope of this utility model.
