It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0030] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0031] like Figure 1The diagram shown is a structural diagram of a reflow soldering track detection device provided in an embodiment of the present invention. The device includes: a mounting assembly, which includes a mounting frame 1 and a set of positioning plates. The mounting assembly is used for the installation of the detection assembly 4. The set of positioning plates are respectively installed on opposite sides of the mounting frame 1. The positioning plates are adapted to the furnace track. At least one positioning plate is installed on the mounting frame 1 through an adjustment assembly 21. The adjustment assembly 21 is used to adjust the distance between the two positioning plates to adapt to tracks of different specifications.

[0032] The detection component 4 is mounted on the mounting bracket 1 and is used to detect the width of the track that is compatible with the positioning plate.

[0033] In this embodiment of the invention, preferably, the reflow soldering track detection device is mainly applicable to the process of connecting components to circuit boards using reflow soldering technology. Due to significant temperature differences, the track deforms according to the principle of thermal expansion and contraction. By detecting the width of the track, it is possible to avoid mismatch between the track width and the circuit board being transported, which could affect the connection between the circuit board and the components. When connecting circuit boards and components using reflow soldering, a track is needed to transport the circuit board to the reflow oven. The track can support the circuit board, making it flat and perpendicular to both sides of the track to facilitate component soldering. When supporting the circuit board, a set of L-shaped plates installed facing each other can be used to support the circuit board. The reflow soldering track detection device is installed below the circuit board and has two positioning plates to position the track. The reflow soldering track detection device needs to be installed to transport the circuit board into the reflow oven. The reflow soldering track width detection device mainly consists of a mounting frame 1, a set of positioning plates, and a detection component 4. The positioning plates and the detection component 4 are respectively mounted on the mounting frame 1. The two positioning plates are positioned on the track to provide a certain positioning function when the circuit board is transported in the reflow soldering oven. Each positioning plate is provided with a first positioning hole 31 for positioning the detection component 4. The detection end of the detection component 4 faces outward so that the width of the track is detected when the track abuts against the detection end of the detection component 4. The distance between the two positioning plates can be adjusted to position tracks of different specifications. When the circuit board is placed on the track, the reflow soldering track detection device can detect whether the width of the track is compatible with the circuit board. It can also avoid the circuit board and the track from being mismatched, which would affect the soldering effect of the circuit board and components or even affect the use of the circuit board.

A first positioning hole 31 of the positioning detection component 4 can be provided on the positioning plate to allow the detection component 4 to detect the width of the track positioned on the positioning plate. The detection component 4 is mounted on the mounting frame 1 and is used to detect the width of the track positioned on the positioning plate so as to detect the width of the track in the reflow oven.

The first positioning plate 2 and the second positioning plate 3 are installed parallel to each other and facing each other. During the adjustment process of the adjustment component 21, when the first positioning plate 2 and the second positioning plate 3 move towards each other, the distance between the first positioning plate 2 and the second positioning plate 3 can be shortened. When the first positioning plate 2 and the second positioning plate 3 move away from each other, the distance between the first positioning plate 2 and the second positioning plate 3 can be increased.

[0037] like Figure 1-5 As shown, in a preferred embodiment of the present invention, the first positioning plate 2 is connected to the mounting frame 1 via a first connecting rod 22. A set of the first connecting rods 22 are provided, and the set of first connecting rods 22 are parallel to each other.

Rotating the adjusting knob 232 causes the connecting rod 234 to move the connecting bracket 231, changing the distance between the connecting bracket 231 and the mounting bracket 1, thereby adjusting the distance between the first positioning plate 2 and the second positioning plate 3.

[0041] In this embodiment of the present invention, preferably, the connecting component 23 installed between the first positioning plate 2 and the mounting frame 1 mainly includes a connecting bracket 231 and an adjusting knob 232.

The rotation of the adjusting knob 232 drives the connecting rod 234 inserted into the sleeve of the mounting frame 1 to move. The connecting rod 234 is threadedly connected to the adjusting knob 232. One end of the connecting rod 234 is fixed on the connecting bracket 231, and the other end is movable and sleeved in the sleeve. The sleeve guides the connecting rod 234 to drive the movement of the connecting bracket 231 and the first positioning plate. Rotating the adjusting knob 232 causes the connecting rod 234 to move, which can adjust the distance between the first positioning plate 2 and the mounting frame, thereby adjusting the distance between the first positioning plate 2 and the second positioning plate 3 to adjust the width of the entire reflow soldering track detection device according to the detection results.

[0044] like Figure 1-5 As shown, in a preferred embodiment of the present invention, the second adjustment component 21 is provided in a set and is respectively installed on the opposite two sides of the mounting frame 1. Each adjustment component 21 is connected to a second connecting rod 32 of the second positioning plate 3 so as to drive the second positioning plate 3 to move and thereby adjust the distance between the first positioning plate 2 and the second positioning plate 3.

[0045] The adjustment assembly 21 includes an elastic element 211 and a guide cylinder 212. The elastic element 211 is located inside the guide cylinder 212 and sleeved on the second connecting rod 32. The guide cylinder 212 is provided with a stepped hole. The larger hole of the stepped hole is used to install the elastic element 211, and the smaller hole of the stepped hole is used to connect with the second connecting rod 32. One end of the elastic element 211 abuts against the protrusion of the second connecting rod 32, and the other end abuts against the step of the stepped hole. The elastic element 211 pushes the second connecting rod 32 to move, thereby adjusting the distance between the first positioning plate 2 and the second positioning plate 3 so that the reflow soldering track detection device is adapted to the track.

[0046] In this embodiment of the present invention, preferably, a set of adjustment components 21 are provided and respectively installed at both ends of the mounting frame 1.

A heat insulation layer 44 is provided between the mounting shell 42 and the control module 45. The heat insulation layer 44 is used to isolate external heat to protect the control module 45 and the detection element 41.

[0048] In this embodiment of the present invention, preferably, the detection component 4 is composed of a mounting shell 42, a control module 45, and a heat insulation layer 44. The detection component 41, the control module 45, and the heat insulation layer 44 are mounted on the mounting frame 1 using the mounting shell 42.

When the heat insulation layer 44 is installed on the mounting shell 42, it can insulate the components installed inside the mounting shell 42 from the temperature, so as to prevent the control module 45 and the detection component 41 inside the mounting shell 42 from being damaged in the high temperature environment of the reflow oven, thus affecting the use of the reflow soldering track detection device.

The detection element 41 is rod-shaped, with the connecting end of the detection element 41 inserted into the connecting frame 432 and the detection end of the detection element 41 passing through the positioning plate.

[0051] In this embodiment of the present invention, preferably, the detection element 41 is mounted on the mounting shell 42 through the second connecting component 43, and the rod-shaped detection element 41 is inserted into the mounting hole and its end is connected to the guide frame 431 through the connecting frame 432, so that when the track abuts against the detection end of the detection element 41, the detection element 41 moves along its length direction to transmit the detected data information to the control module 45. At this time, the connecting spring 433 is also compressed as the detection element 41 moves. After the signal transmission is completed, the track disengages from the abutment of the detection element 41, and the connecting spring 433 drives the detection element 41 to reset so as to detect the next track.

[0052] Preferably, the detection element 41 can be a photoelectric sensor or a pressure sensor. When the detection element 41 is a photoelectric sensor, the photoelectric sensor can detect the distance that the detection element 41 moves along its length after being pressed down by the track, and thus transmit the detected signal to the control module 45. A set of photoelectric sensors can also be provided and installed on the positioning plates to detect the width of the track. When the detection element 41 is a pressure sensor, it is installed at the end of the detection element 41 that abuts against the track.

The first mounting groove is used to install the detection component 4, and the second mounting groove is used to install the adjustment component 21. Multiple second positioning holes for positioning the positioning plate are respectively provided on the opposite two sides of the mounting frame 1.

[0054] In this embodiment of the present invention, preferably, the mounting frame 1 can be a rectangular frame with a certain height, and a first mounting slot of different sizes and a set of second mounting slots are provided on the top surface of the mounting frame 1. The two second mounting slots are arranged on both sides of the first mounting slot, and the volume of the first mounting slot is larger than the volume of the second mounting slot. The first mounting slot is used to install the mounting shell 42 of the detection component 4, and the second mounting slot is used to install the elastic element 211 and the guide cylinder 212 of the adjustment component 21. The second positioning hole provided on the side of the mounting frame 1 can be used to position the first connecting rod 22 of the first positioning plate 2, so that when the adjustment component 21 drives the second positioning plate 3 to move, the first positioning plate 2 can be completely fixed on the mounting frame 1, so that the adjustment component 21 drives the second positioning plate 3 to move to adjust the distance between the first positioning plate 2 and the second positioning plate 3. Alternatively, the second positioning hole can be used to guide the first positioning plate 2 to move so that the first positioning plate 2 and the second positioning plate 3 can move towards each other or away from each other to adjust the distance.
