Description

Technical Field

[0001] This invention relates to the field of boxless molding technology, and in particular to an inspection and alignment device for boxless molding during box assembly. Background Technology

[0002] Normally, after resin sand casting is assembled, the quality of the casting must be checked from the riser to see if the mold is misaligned. However, due to thinner wall thickness or process design, this cannot be checked after casting. Therefore, it is necessary to design an alignment device that can show whether the internal casting is misaligned from the outside to solve the above problem. Summary of the Invention

[0003] The purpose of this invention is to solve the above-mentioned problems by providing an inspection and alignment device for boxless box assembly.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] An inspection and alignment device for boxless box assembly includes:

[0006] An electric slide rail, wherein at least one fixing angle iron for fixed installation is provided on the electric slide rail;

[0007] The walking base is used to place the upper mold and the lower mold. The walking base is located on the electric slide rail and is powered by the electric slide rail to move in the opposite direction along the electric slide rail.

[0008] A detection component is mounted on an electric slide rail and is used to detect the alignment of the upper and lower molds when the walking base moves.

[0009] Optionally, the detection component includes:

[0010] A testing frame, which is mounted on an electric slide rail;

[0011] A laser emitter for emitting modulated laser light;

[0012] A photosensitive component, wherein the photosensitive component is used to sense modulated laser emitted by a laser emitter and pulls up the pin level when laser is received;

[0013] A displacement driving assembly, which is mounted on a detection frame for adjusting the position of a laser emitter;

[0014] A power assembly, which is mounted on an electric slide rail, is used to provide power to the displacement drive assembly.

[0015] Optionally, the laser emitter's emitted beam is positioned close to the walking base and the lower mold.

[0016] Optionally, the photosensitive assembly comprises a light-absorbing shell, a total reflection mirror, a semi-transparent mirror, and a photosensitive element;

[0017] The light-absorbing shell is installed on the top of the detection frame and is parallel to the side of the walking base. The light-absorbing shell adopts a semi-open structure with the opening facing the laser emitter. The total reflection mirror is set at the inner bottom of the light-absorbing shell, and the semi-transparent lens is set at the opening of the light-absorbing shell.

[0018] The laser emission angle of the laser emitter is deflected from the vertical direction by 10° to 60°.

[0019] Optionally, the displacement driving component includes:

[0020] A ball screw, the two ends of which are mounted on a testing frame via bearings;

[0021] A ball nut, which is threadedly connected to a ball screw;

[0022] The optical bar has both ends welded to the detection frame;

[0023] A linear bearing, wherein the linear bearing is slidably connected to the optical bar;

[0024] A laser emitter mounting base is provided for mounting a laser emitter, and ball nuts and linear bearings are also mounted on the laser emitter mounting base.

[0025] Optionally, the number of detection components is two and they are symmetrically arranged on both sides of the electric slide rail. The two detection components share a power component, and the two laser emitter mounting bases are fixed together by a connecting bracket.

[0026] Compared with the prior art, the present invention has the following advantages:

[0027] This invention enables the upper and lower molds to automatically move to the inspection station for alignment inspection by setting up an electric slide rail and a traveling base.

[0028] This invention, by setting up a detection component, can perform alignment detection on the upper and lower molds that have moved to the detection station. Through the displacement of the laser emitter and the cooperation of the photosensitive component, it can quickly detect misalignment of the upper and lower molds that is not visible to the human eye.

[0029] This invention employs a multi-angle, continuous receiving photosensitive element, which can detect moving laser light sources in real time. This method only requires setting up one photosensitive element, thereby solving the problem of blind spots between multiple photosensitive elements and providing a prerequisite for subsequent alignment detection.

Detailed Implementation

[0035] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0036] Reference Figure 1 Make a wooden strip of equal size at the same position on the upper and lower parting surfaces inside the sand frame without a box shape. After demolding, there will be a groove 15 on the outside of the sand mold. The groove 15 is set in half at the connection of the outer surfaces of the upper mold 13 and the lower mold 14. Through this method, it can be seen with the naked eye whether the upper mold 13 and the lower mold 14 are aligned.

[0037] When observing alignment issues that are not perceptible to the naked eye, the following approach is adopted:

[0038] Reference Figure 2-4 Electric slide rail 1, the electric slide rail 1 is provided with at least one fixed angle iron 2 for fixed installation, the fixed angle iron 2 is installed on the ground by expansion bolts.

[0039] The traveling base 4 is used to place the upper mold 13 and the lower mold 14. The traveling base 4 is located on the electric slide rail 1 and is powered by the electric slide rail 1 to move in the opposite direction along the electric slide rail.

[0040] The detection component is mounted on the electric slide rail 1. The detection component is used to detect the alignment of the upper mold 13 and the lower mold 14 when the walking base 4 moves. The specific settings and principles of the detection component will be explained in detail below:

[0041] Reference Figure 2 and Figure 3 The detection assembly includes a detection frame 3, a laser emitter 11, a photosensitive component 5, a displacement drive component, and a power component 12, with the specific connection method as follows:

[0042] The testing frame 3 is installed on the electric slide rail 1. The testing frame 3 is located on the side of the electric slide rail 1, and the two can be connected by welding or bolting.

[0043] The laser emitter 11 is used to emit modulated laser light, which can continuously emit 200kHz laser light. It should be noted that the emitted light of the laser emitter 11 is close to the walking base 4 and the lower mold 14. That is, the lower mold 14 should be aligned with the walking base 4 when it is mounted on it. This arrangement provides the prerequisite for the subsequent alignment detection of the upper mold 13 and the lower mold 14.

[0044] The photosensitive component 5 is used to sense the modulated laser emitted by the laser emitter 11 and pulls up the pin level when the laser is received. The photosensitive component 5 consists of a light-absorbing shell 51, a total reflection mirror 52, a semi-transparent mirror 53, and a photosensitive element 54. (Refer to...) Figure 4 .

[0045] The light-absorbing shell 51 is installed on the top of the detection frame 3 and is set parallel to the side of the walking base 4. The parallel setting ensures the accuracy of the detection.

[0046] The outer surface of the light-absorbing shell 51 can be printed with black ink, so that its inner wall can absorb stray light from the outside.

[0047] The light-absorbing shell 51 adopts a semi-open structure with the opening facing the laser emitter 11. The total reflection mirror 52 is located at the inner bottom end of the light-absorbing shell 51, and the semi-reflective lens 53 is located at the opening of the light-absorbing shell 51. After the laser passes through the semi-reflective lens 53, it will be continuously reflected between the semi-reflective lens 53 and the total reflection mirror 62 until it is received by the photosensitive element 54. The photosensitive element 54 can be a photodiode, which can output a low level under normal conditions and pull up the pin level when it receives laser light. The MCU can continuously monitor the pin level, thereby determining whether the laser light is blocked by the change in level, and thus determining whether the moving upper mold 13 and lower mold 14 are aligned.

[0048] The laser emission angle of laser emitter 11 is deflected from the vertical direction by 10° to 60° (refer to...). Figure 4 (See the example diagram of the light path at angles of 10° and 60° in the figure). The smaller the deflection angle, the greater the loss of light in continuous reflection, which reduces the sensitivity of the device. When the deflection angle is increased to 60°, there may be a reflection blind zone. Therefore, the deflection angle should be selected according to the length of the light-absorbing shell 51. While ensuring that the photosensitive element 5 can sense the light, the deflection angle should be reduced as much as possible.

[0049] Reference Figure 2 and Figure 3The displacement drive assembly is mounted on the detection frame 3 to adjust the position of the laser emitter 11. The displacement drive assembly includes: a ball screw 7, a ball nut 6, a linear guide bar 8, a linear bearing 9, and a laser emitter mounting base 10, as detailed below:

[0050] The two ends of the ball screw 7 are mounted on the test frame 3 via bearings, and the ball nut 6 is threadedly connected to the ball screw 7.

[0051] Both ends of the optical bar 8 are welded to the detection frame 3, and the linear bearing 9 is slidably connected to the optical bar 8.

[0052] The laser emitter mounting base 10 is used to mount the laser emitter 11, and the ball nut 6 and the linear bearing 9 are also mounted on the laser emitter mounting base 10.

[0053] The power assembly 12 is mounted on the electric slide rail 1. The power assembly 12 is used to provide power to the displacement drive assembly. In this embodiment, the power assembly 12 consists of a servo motor and a reducer (see reference). Figure 2 ).

[0054] Example 2

[0055] In this embodiment, there are two detection components, which are symmetrically arranged on both sides of the electric slide rail 1 for synchronous detection. The two laser emitter mounting bases 10 are fixed together by a connecting bracket 16, so that the two detection components share a power component 12.

[0056] In the detection component that is not directly connected to the power component 12, the ball screw 7 and ball nut 6 are replaced with optical rod 8 and linear bearing 9. Since only the ball screw 7 connected to the power component 12 is useful, the ball screw 7 and ball nut 6 on the other side are replaced. The two optical rods are slidably connected to the laser emitter mounting base 10, thereby reducing the motion resistance of the laser emitter mounting base 10 on the other side and improving stability.

[0057] The above description is only a preferred embodiment of the present invention. It is impossible to exhaustively describe all embodiments here. However, the protection scope of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the protection scope of the present invention.
