Description
Technical Field
[0001] The invention belongs to the technical field of large-size injection molded parts detection, in particular to a large-size injection molded parts rapid detection device. Background Art
[0002] Vanadium battery is a new type of high-efficiency electric energy conversion and storage device. Due to its advantages of low manufacturing cost, long service life and compliance with environmental protection requirements, it has gradually become a research focus in recent years. Most vanadium liquid batteries are used in the form of battery stacks, and flow plates are often required to guide the electrolyte, so flow plates are extremely critical to the production and manufacturing of vanadium batteries. At present, high-density polyethylene is mostly used on the market to inject thin-walled large-size flow plates. However, high-density polyethylene injection moldings are greatly affected by temperature. When the temperature is too high, it is easy to cause defects such as warping, deformation, and bubbles in the injection moldings, and even cause degradation, reducing the quality and performance of the products; when the temperature is too low, the melt fluidity deteriorates, which may lead to insufficient injection molding, insufficient filling, rough surface, weld marks and other problems, which will also affect the appearance and mechanical properties of the products. Therefore, after the injection molding of high-density polyethylene injection moldings is completed, strict testing is required to eliminate unqualified injection moldings. At present, when most workshops detect whether polyethylene injection molded parts are qualified, they usually use tools such as calipers and micrometers to measure key dimensions to detect whether the injection molded parts meet the tolerance range required by the design. However, this detection method has a slow detection speed and low efficiency. At the same time, it may be difficult to accurately measure the dimensions of complex shapes, complex surfaces or special structures. In addition, the measurement personnel's operating proficiency and reading accuracy may also introduce certain human errors.
[0003] In the prior art, different injection molded parts have different detection methods, but there is no good method for rapid detection of large-sized vanadium battery flow channel plate injection molded parts. The traditional manual detection method is too inefficient and has the defect of low reliability.
[0004] To this end, the present invention provides a large-size injection molded part rapid detection device. Summary of the invention
[0005] In order to make up for the deficiencies of the prior art and solve the problems in the prior art that large-sized vanadium battery flow channel plate injection molded parts cannot be quickly inspected and manual inspection is inefficient and unreliable, the present invention proposes a large-sized injection molded parts rapid inspection device.
[0006] The technical solution adopted by the present invention to solve its technical problems is as follows: A large-size injection molding part rapid detection device described in the present invention includes a mounting plate. The top end of the mounting plate is fixedly connected with uniformly distributed limiting columns. The outer side of the mounting plate is fixedly connected with uniformly distributed fixing frames. The bottom end of the fixing frame is fixedly connected with a cylinder. The output end of the cylinder is fixedly connected with a measuring bracket. A measuring component is arranged on the outer side of the measuring bracket.
[0007] Further, the measuring component includes a torsion spring. The inner side of the top end of the measuring bracket is snap-fitted with a torsion spring. The top end of the torsion spring is snap-fitted with a rotating arm. The rotating arm is rotatably connected with the measuring bracket. The inner side of the bottom end of the measuring bracket is fixedly connected with an angle sensor. The angle sensor is snap-fitted with the rotating arm. A limiting component is arranged on the side of the rotating arm away from the cylinder. A contact wheel is rotatably connected to the top side of the end of the rotating arm close to the cylinder.
[0008] Further, the limiting component includes a second chute. A second chute is opened on the side of the measuring bracket away from the cylinder. A limiting rod is rotatably connected to the bottom side of the end of the rotating arm away from the cylinder. The limiting rod is slidably connected with the second chute.
[0009] Further, the outer side of the top end of the mounting plate is fixedly connected with uniformly distributed support frames. The outer wall of the right support frame on the right side is fixedly connected with a motor. The output end of the motor is fixedly connected with a bidirectional lead screw. The bidirectional lead screw is rotatably connected with the support frame. The inner side of the top end of the support frame is fixedly connected with front and rear opposite sliding rods. The outer sides of the middle parts of the sliding rods are slidably connected with left and right opposite first limiting frames. The first limiting frames are threadedly connected with the bidirectional lead screw.
[0010] Further, the top end of the first limiting frame is fixedly connected with a support plate. The left side of the top end of the support plate is fixedly connected with uniformly distributed visual sensors.
[0011] Further, a first chute is opened on the inner side of the bottom end of the limiting column. A transmission frame is slidably connected inside the first chute. The outer side of the transmission frame is fixedly connected with a lifting sleeve. The lifting sleeve is slidably connected with the limiting column.

[0013] Further, a runner plate is snap-fitted on the outer side of the limiting column. The runner plate is snap-fitted with the fixing rod.
[0014] The beneficial effects of the present invention are as follows:
[0015] 1. A rapid detection device for large-sized injection molded parts according to the present invention. After the runner plate is transported by the conveyor belt, the cylinder is used to drive the measuring bracket to retreat or advance, so that a plurality of measuring brackets drive the measuring components to detect the injection molding situation of the large-sized injection molded parts, realizing the rapid detection of the runner plate, and quickly screening qualified products and unqualified products.
[0016] 2. A rapid detection device for large-sized injection molded parts according to the present invention. The motor drives the bidirectional lead screw to rotate, so that the first limit frame, the support plate and the vision sensor are simultaneously driven by the bidirectional lead screw to move left and right, thereby detecting the surface of the runner plate.

Detailed implementation manners
[0027] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation manners.
[0028] Embodiment 1:
[0029] As Figures 1 to 7 shown, a large-size injection molding part rapid detection device of the present invention includes a mounting plate 1. Uniformly distributed limit posts 12 are fixedly connected to the top end of the mounting plate 1. The mounting plate 1 supports and fixes the limit posts 12. Uniformly distributed fixed frames 4 are fixedly connected to the outside of the mounting plate 1. A plurality of grooves are provided on the outside of the mounting plate 1, and the fixed frames 4 are fixed through the grooves. A cylinder 41 is fixedly connected to the bottom end of the fixed frame 4. The fixed frame 4 fixes the cylinder 41. The output end of the cylinder 41 is fixedly connected to a measuring bracket 42. The cylinder 41 fixes the measuring bracket 42 and drives the measuring bracket 42 to move at the same time. A measuring component is arranged on the outside of the measuring bracket 42.
[0030] The measuring component includes a torsion spring 44. The torsion spring 44 is snap-fitted to the inner side of the top end of the measuring bracket 42. The bottom end of the torsion spring 44 is limited by an angle sensor 43. The top end of the torsion spring 44 is snap-fitted to a swing arm 45. The swing arm 45 limits the top end of the torsion spring 44. At the same time, the torsion spring 44 drives the swing arm 45 to rotate counterclockwise with the measuring bracket 42 as the stress point. The swing arm 45 is rotatably connected to the measuring bracket 42. The measuring bracket 42 limits the swing arm 45. An angle sensor 43 is fixedly connected to the inner side of the bottom end of the measuring bracket 42. The measuring bracket 42 fixes the angle sensor 43. The angle sensor 43 is snap-fitted to the swing arm 45. A limit component is arranged on the side of the swing arm 45 away from the cylinder 41. A contact wheel 47 is rotatably connected to the top side of one end of the swing arm 45 close to the cylinder 41. The swing arm 45 limits the contact wheel 47. The angle sensor 43 accurately measures the rotation angle of the contact wheel 47 after contacting the runner plate 11. The linear distance can be calculated from the rotation angle of the contact wheel 47, becoming a linear measurement.
[0031] The limiting component includes a second sliding groove 48. A second sliding groove 48 is provided on the side of the measuring bracket 42 away from the cylinder 41. The bottom side of the end of the swing arm 45 away from the cylinder 41 is rotatably connected to a limiting rod 46. The limiting rod 46 is slidably connected to the second sliding groove 48, and the rotation angle of the limiting rod 46 is limited by the second sliding groove 48.
[0032] On the outer side of the top end of the mounting plate 1, uniformly distributed support frames 2 are fixedly connected. The support frames 2 are fixed by the mounting plate 1. On the outer wall of the right side of the right support frame 2, a motor 21 is fixedly connected. The motor 21 is fixed by the support frame 2. The output end of the motor 21 is fixedly connected to a bidirectional lead screw 23. The bidirectional lead screw 23 is fixed by the motor 21. At the same time, the motor 21 drives the bidirectional lead screw 23 to rotate. The bidirectional lead screw 23 is rotatably connected to the support frames 2. The two sides of the bidirectional lead screw 23 are supported and limited by the two support frames 2 at the same time. Inside the top end of the support frame 2, front and rear opposite sliding rods 22 are fixedly connected. The sliding rods 22 are limited by the support frame 2. On the outer side of the middle end of the sliding rods 22, left and right opposite first limiting frames 24 are slidably connected. The first limiting frames 24 are limited by the sliding rods 22. The first limiting frames 24 are threadedly connected to the bidirectional lead screw 23. The rotation of the bidirectional lead screw 23 drives the first limiting frames 24 to move left and right. At the same time, the first limiting frames 24 are limited by the sliding rods 22 to prevent the first limiting frames 24 from rotating with the bidirectional lead screw 23.
[0033] The top end of the first limiting frame 24 is fixedly connected to a support plate 25. The support plate 25 is fixed by the first limiting frame 24. On the left side of the top end of the support plate 25, uniformly distributed vision sensors 26 are fixedly connected. The vision sensors 26 are fixed by the support plate 25. And the bidirectional lead screw 23 drives the first limiting frames 24, the support plate 25 and the vision sensors 26 to move left and right, so as to detect the top surface of the runner plate 11.
[0034] Inside the bottom end of the limiting column 12, a first sliding groove 13 is provided. Inside the first sliding groove 13, a transmission frame 32 is slidably connected. The transmission frame 32 is limited by the first sliding groove 13. On the outer side of the transmission frame 32, a lifting sleeve 3 is fixedly connected. The lifting sleeve 3 is fixed by the transmission frame 32. The lifting sleeve 3 is slidably connected to the limiting column 12. The lifting angle of the lifting sleeve 3 is limited by the limiting column 12. The bottom end of the lifting sleeve 3 is fixedly connected to a first spring 31. The top end of the first spring 31 is fixed by the lifting sleeve 3. The first spring 31 is fixedly connected to the mounting plate 1. The first spring 31 is supported and fixed by the mounting plate 1.
[0035] The inner side of the top end of the transmission frame 32 is rotatably connected to a fixed rod 33. The middle end of the fixed rod 33 is limited by the transmission frame 32. The inner side of the fixed rod 33 is rotatably connected to a second limiting frame 34. The second limiting frame 34 is fixedly connected to the top end of the limiting column 12. The second limiting frame 34 is fixed by the limiting column 12. At the same time, one end of the inner side of the fixed rod 33 is limited by the second limiting frame 34. Thus, the lifting of the transmission frame 32 drives the fixed rod 33 to rotate around the connection point of the fixed rod 33 and the second limiting frame 34.
[0036] The flow channel plate 11 is snap-fitted on the outer side of the limiting column 12. The position of the flow channel plate 11 is fixed by the limiting column 12. The flow channel plate 11 is snap-fitted with the fixed rod 33. The flow channel plate 11 is clamped by the fixed rod 33. At the same time, due to the large frictional force between the transmission frame 32 and the limiting column 12, the relative vibration between the mounting plate 1 and the flow channel plate 11 caused by external vibration is damped, reducing the influence of vibration on the detection result.
[0037] Working principle: When the surface treatment device for large-size injection molding part detection technology is running, first place the flow channel plate 11 on the top end of the mounting plate 1, align the limiting column 12 with the through hole on the flow channel plate 11 and snap-fit them. Then, the weight of the flow channel plate 11 itself drives the lifting sleeve 3 to move downward and compress the first spring 31. At the same time, the lifting sleeve 3 drives the fixed rod 33 to rotate downward through the transmission frame 32, thereby pressing down the flow channel plate 11 to fix the flow channel plate 11. After that, the motor 21 drives the bidirectional lead screw 23 to rotate, and at the same time, the bidirectional lead screw 23 drives the first limiting frame 24 to move left and right on the sliding rod 22. Thus, the first limiting frame 24 drives the support plate 25 and the vision sensor 26 to move synchronously to detect the top end of the flow channel plate 11. Then, multiple cylinders 41 drive the measuring bracket 42 to move inward simultaneously. Thus, the measuring bracket 42 drives the swing arm 45 to move inward synchronously and drives the contact wheel 47 on the swing arm 45 to contact the flow channel plate 11. After the contact wheel 47 contacts the edge of the flow channel plate 11 to be measured, it rotates, and the rotation angle is monitored by the angle sensor 43 to quickly detect the workpiece.
