Description
Technical Field
[0001] The utility model belongs to the technical field of circuit detection, and in particular relates to a workpiece circuit detection device. Background Art
[0002] Currently, in the field of injection molding, circuit components are usually encapsulated by injection molding to form the desired product; however, when such injection molding is performed using such injection molding materials, there is often a possibility of damaging the electronic components, which may result in the molded workpiece being unable to achieve the expected circuit continuity.
[0003] At present, existing manufacturers usually arrange manual quality inspection of workpiece products to deal with such possible adverse situations. Manual quality inspection usually involves manually aligning the test PIN head with the circuit contacts of the workpiece product and supplying power to the workpiece product through the test PIN head to determine whether the internal circuit of the workpiece product is turned on. When the internal circuit of the workpiece product is turned on, the built-in LED lamp beads of the workpiece will light up, and the quality of the workpiece product is judged to be normal; conversely, if the internal circuit of the workpiece product is not turned on, the LED lamp beads will not light up, and the quality of the workpiece product is judged to be poor.
[0004] The inventors have found that this testing method is not only time-consuming and labor-intensive, but also difficult to align the PIN head, which places a heavy burden on workers. Therefore, there is an urgent need to design a new circuit detection device for workpieces to simplify the detection process and improve detection efficiency. Utility Model Content
[0005] The technical problem to be solved by the utility model is to provide a new workpiece circuit detection device to solve the problem of time-consuming and labor-consuming in the existing manual alignment of a PIN head and a workpiece circuit contact.
[0006] In order to solve the above technical problems, the utility model discloses a workpiece circuit detection device, which includes a frame, the frame includes a first substrate and a second substrate set at an angle, and also includes a detection workpiece, the detection workpiece includes a first connecting rod, a second connecting rod, a third connecting rod and a detection table, the first connecting rod, the second connecting rod and the third connecting rod are hinged in sequence, the end of the third connecting rod away from the second connecting rod is connected to the detection table, and the third connecting rod is slidable compared to the second substrate; wherein, the end of the first connecting rod away from the second connecting rod is rotatably connected to the second substrate, and a plurality of mounting grooves are provided on the first substrate.
[0007] At present, existing manufacturers usually arrange manual quality inspection of workpiece products to deal with such possible adverse conditions. Manual quality inspection usually involves manually aligning the test PIN head with the circuit contacts of the workpiece product to supply power to the workpiece product through the test PIN head to determine whether the internal circuit of the workpiece product is conductive. In actual application, manual alignment of the test PIN head with the circuit contacts is time-consuming and labor-intensive, which greatly increases the burden on operators.
[0008] Therefore, in the present utility model, the inventor has designed a new workpiece circuit detection device, which can effectively assist workers in aligning the test PIN head with the circuit contacts. In actual application, the above-mentioned test PIN head can be integrated on the detection table, and the detection table can be pushed by the third connecting rod; therefore, the inventor also arranges the third connecting rod to be able to slide relative to the second substrate, so as to indirectly limit the movement of the detection table by limiting the sliding trajectory of the third connecting rod, thereby ensuring that the test PIN head on the detection table can effectively align with the workpiece to be detected in the multiple installation grooves arranged on the first substrate.
[0009] It should be pointed out that in the present invention, in order to facilitate the operator to control the sliding of the third connecting rod relative to the second substrate, a first connecting rod and a second connecting rod are further provided, so that by adjusting the installation form of the first connecting rod and the second connecting rod, the operator can control the first connecting rod to rotate relative to the second substrate, which can indirectly drive the second connecting rod and the third connecting rod hinged with the second connecting rod to move, so that the third connecting rod can further push the above-mentioned detection platform to move when it moves, so that the detection platform moves closer to the direction of the first substrate. The driving process is relatively simple, which can greatly simplify the operating difficulty of the operator.
[0010] Furthermore, in the workpiece circuit detection device described in the utility model, a protruding handle is provided at one end of the first connecting rod close to the second connecting rod.
[0011] In the above technical solution of the utility model, in order to simplify and facilitate the operator to use the workpiece circuit detection device, a protruding handle can be provided at one end of the first connecting rod close to the second connecting rod. At this time, the first connecting rod and the above handle can form an "L" shape together.
[0012] The operator pulls the handle and controls the handle to rotate relative to the second substrate so that the handle approaches the first substrate. At this time, the first connecting rod can move together, and the second connecting rod hinged to the first connecting rod will also be displaced and move toward the direction close to the first substrate; accordingly, since the sliding direction of the third connecting rod hinged to the second connecting rod is limited, the third connecting rod will push the inspection table close to the first substrate along the preset sliding direction under the push of the second connecting rod, so that the test PIN head on the inspection table can effectively align with the workpiece to be inspected in the multiple mounting grooves set in the first substrate.
[0013] At this time, by powering the workpiece to be inspected through the test PIN head, it is possible to determine whether the internal circuit of the workpiece product is conductive. When the internal circuit of the workpiece product is conductive, the built-in LED lamp beads of the workpiece will light up, and the quality of the workpiece product is judged to be normal; conversely, if the internal circuit of the workpiece product is not conductive, the LED lamp beads will not light up, and the quality of the workpiece product is judged to be poor.
[0014] Furthermore, in the workpiece circuit detection device described in the utility model, an anti-slip structure is provided on the handle.
[0015] In the above technical solution of the utility model, in order to improve the use effect of the operator, an anti-slip structure can also be provided on the handle. In actual application, the anti-slip structure can be specifically an anti-slip cloth wrapped around the handle.
[0016] Furthermore, in the workpiece circuit detection device described in the utility model, the first substrate and the second substrate are arranged at an angle of 90°.
[0017] Furthermore, in the workpiece circuit detection device described in the utility model, a detachably connected fixing seat is provided on the second substrate, and the fixing seat includes a first leg and a second leg, so that the first connecting rod is hinged to the first leg; wherein, a shaft sleeve is provided on the second leg, and the third connecting rod can be slidably arranged through the shaft sleeve.
[0018] Furthermore, in the workpiece circuit detection device described in the utility model, a plurality of long holes or strip holes are provided on the second substrate, and the fixing seat is installed and fixed by screws passing through the long holes or strip holes, so that the fixing seat can be detachably arranged on the second substrate.
[0019] In the above technical solution of the utility model, in order to enhance the adjustability and adaptability of the workpiece circuit detection device, in actual application, the above second substrate can be specifically coordinated with the first connecting rod and the third connecting rod through a detachable fixing seat. That is to say, in order to obtain a better implementation effect, a plurality of long holes or strip holes can be set on the second substrate to facilitate the adjustment of the position of the fixing seat on the above second substrate when installing the fixing seat. Wherein, when setting, the fixing seat can specifically include a first leg and a second leg, the above first leg is used to be hinged with the first connecting rod, and the above second leg is provided with a sleeve, so that the above third connecting rod can be slidably set through the sleeve, and the sliding direction of the third connecting rod is limited by the sleeve, thereby indirectly limiting the moving direction of the detection platform.

[0036] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in conjunction with the implementation modes and the accompanying drawings.
[0037] Please refer to Figures 1 to 4 As shown, in this embodiment, the utility model designs a new workpiece circuit detection device, which includes a workpiece circuit detection device frame and a detection workpiece 3 arranged on the frame. The frame includes a first substrate 1 and a second substrate 2 arranged at an angle of 90°, that is, the first substrate 1 extends in the horizontal direction, and the second substrate 2 extends in the vertical direction.
[0038] like Figure 1 and Figure 2As shown, in this embodiment, four mounting grooves 11 are provided on the substrate. The four mounting grooves 11 are used to accommodate the workpieces to be detected, and the groove shape thereof matches the outer contour of the workpieces to be detected, so that four workpieces to be detected can be effectively accommodated and positioned at one time.
[0039] Accordingly, in this embodiment, a detachably connected fixing seat 21 is provided on the second substrate 2, and the fixing seat 21 includes a first leg 211 and a second leg 212. The first leg 211 is higher than the second leg 212 in the vertical height direction, and the first leg 211 extends in an oblique upward direction away from the second substrate 2, and the second leg 212 extends in an oblique downward direction away from the second substrate 2. A shaft sleeve 213 is provided at the end of the second leg 212 away from the second substrate 2.
[0040] Of course, in order to obtain a better implementation effect, a plurality of long holes or strip holes can be set on the second substrate 2, and the above-mentioned fixing seat 21 is fixed on the second substrate 2 by screws passing through the long holes or strip holes, so as to facilitate the adjustment of the position of the fixing seat 21 on the above-mentioned second substrate 2 during installation.
[0041] like Figure 1-Figure 4 As shown, in the workpiece circuit detection device, the detection workpiece 3 provided specifically includes a first connecting rod 31, a second connecting rod 32, a third connecting rod 33 and a detection platform 34. Among them, four test PIN heads 341 are provided on the detection platform 34, and the four test PIN heads 341 each include four PIN pins arranged side by side, and the four test PIN heads 341 are arranged directly opposite to the four mounting slots 11 on the first substrate 1.
[0042] In the present embodiment, the first link 31, the second link 32 and the third link 33 are hinged in sequence, and the end of the third link 33 away from the second link 32 is fixedly connected to the detection table 34; the end of the first link 31 away from the second link 32 is rotatably connected to the second substrate 2, and the end of the first link 31 close to the second link 32 is provided with a protruding handle 35, and the handle 35 is wrapped with anti-slip cloth; and, in the present embodiment, the third link 33 is slidably arranged through the shaft sleeve 213 of the fixed seat 21, so that the third link 33 can slide relative to the second substrate 2, thereby limiting the movement direction of the third link 33.
[0043] In actual application, the operator pulls the handle 35 and controls the handle 35 to rotate relative to the second substrate 2 so that the handle 35 approaches the first substrate 1. At this time, the first connecting rod 31 connected to the handle 35 can move together, and the second connecting rod 32 hinged to the first connecting rod 31 will also be displaced and move toward the direction close to the first substrate 1; accordingly, since the sliding direction of the third connecting rod 33 hinged to the second connecting rod 32 is limited by the sleeve 213 of the fixed seat 21, the third connecting rod 33 will push the detection platform 34 along the preset sliding direction (vertical downward direction) under the push of the second connecting rod 32, so that the four test PIN heads 341 on the detection platform 34 can be effectively aligned with the workpiece to be detected set in the four mounting grooves 11 of the first substrate 1.
[0044] At this time, the four PIN pins of the four test PIN heads 341 can effectively align with the four circuit contacts of the workpiece to be inspected, so as to power the workpiece to be inspected through the test PIN head 341, thereby determining whether the internal circuit of the workpiece to be inspected is turned on. When the internal circuit of the workpiece to be inspected is turned on, the built-in LED lamp beads of the workpiece to be inspected will light up, and it is determined that the circuit of the workpiece to be inspected is normal. On the contrary, if the internal circuit of the workpiece to be inspected is not turned on, the LED lamp beads will not light up, and it is determined that the circuit of the workpiece to be inspected is abnormal.
[0045] Accordingly, in order to ensure that the detection platform 34, under the drive of the third connecting rod 33, can effectively align its own test PIN head 341 with the circuit contacts of the workpiece to be detected arranged on the four mounting grooves 11 of the first substrate 1, in the present embodiment, two guide rods 4 are also provided, one end of the two guide rods 4 is connected to the first substrate 1, and the other end thereof passes through the detection platform 34 and is connected to the second substrate 2, so as to guide the movement direction of the detection platform 34.
[0046] Moreover, in this embodiment, considering that the conventional 220V voltage is not the working voltage of common workpieces, in order to improve safety and reliability, a step-down module is also provided on the above-mentioned testing platform 34. The four test PIN heads 341 of the testing platform 34 are all electrically connected to the above-mentioned step-down module, and the above-mentioned step-down module is also connected to an external 220V power supply. The step-down module can specifically step down the 220V voltage of the external power supply and convert it into a 12V safe voltage for power supply.
