Description

Technical Field

[0001] The invention relates to the technical field of transmission detection, and in particular to a transmission machine for injection molded finished product detection. Background Art

[0002] Injection molded products are various products manufactured through plastic injection molding process. Injection molding is a processing method that heats thermoplastic or thermosetting materials to a fluid state, then injects them into a mold, and forms the desired shape after cooling and solidification. Injection molded products are usually used in electronic product housings, automotive parts and industrial parts. Some injection molded products are used in Volvo's 48V battery pack (called battery box) and installed in the car's engine compartment. During the processing of the injection molded product, five iron parts will be installed in the preset tooling nine times, and then injection molded into a battery box.

[0003] After the injection molded product (battery box) is processed, it is necessary to use the detection tooling to detect the iron parts of the injection molded product to determine whether the iron parts in the injection molded product meet the normal process. However, the following problems still exist: when the injection molded product is detected for iron parts, the injection molded product needs to be transported to the designated area via a conveyor belt, and then the staff will install the injection molded product in the detection tooling for detection. When the detection is normal, the staff can take it out normally. If the detection is abnormal, the injection molded product will be locked for the convenience of identification by the staff. However, this method requires the staff to install, detect and disassemble each injection molded product, which is troublesome to operate and affects the detection efficiency. In particular, when an abnormality is detected, the injection molded product will be locked in the detection tooling, resulting in an increase in the workload of the operator, and the detection efficiency is not high. Therefore, a conveyor for injection molded product detection is designed, so that the conveyor can automatically position and fix the injection molded product and detect iron parts during the transmission of the injection molded product, and the qualified injection molded products and unqualified injection molded products can be automatically grouped and collected according to the detection results during the detection process, which is convenient for the staff to subsequently process and carry out. Summary of the invention

[0031] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0032] Example 1, reference Figure 1-Figure 8 , which is the first embodiment of the present invention, provides a conveyor for detecting injection molded products, including a bottom plate 1 and injection molded products (not shown in the figure), a front conveyor frame 2 and a rear conveyor frame 3 fixedly mounted on the bottom plate 1, a conveyor belt 4 sleeved on the front conveyor frame 2 and the rear conveyor frame 3, and also includes a conveying unit mounted on the bottom plate 1, and the conveying unit includes a positioning component and a detection component mounted on the bottom plate 1;

[0033] The positioning components include a plurality of receiving blocks 5 fixedly mounted on the side walls on both sides of the front transmission frame 2, a limiting rod 6 fixedly mounted between two corresponding receiving blocks 5, a detection frame 7 fixedly mounted on the bottom plate 1, a cylinder 8 fixedly mounted on the bottom plate 1, a support plate 9 fixedly mounted on the telescopic end of the cylinder 8, a plurality of slide rails 10 fixedly mounted on the side walls of the detection frame 7, a slide rod 11 slidably mounted on the corresponding slide rails 10, a lifting plate 12 fixedly mounted between the plurality of slide rods 11, two connecting plates 13 fixedly mounted at the lower end of the lifting plate 12, a mounting plate 14 fixedly mounted between the lower ends of the two connecting plates 13, a light sensor 15 fixedly mounted on the side walls of the detection frame 7, a clamping assembly mounted on the mounting plate 14, and a driving assembly mounted between the mounting plate 14 and the detection frame 7;

[0034] The distance between the two limit rods 6 is equal to the width of the injection molded product. The detection frame 7 is in the shape of a U-shaped letter "U". The detection frame 7 is located between the front transmission frame 2 and the rear transmission frame 3. The cylinder 8 and the support plate 9 are located between the front transmission frame 2 and the rear transmission frame 3. A T-shaped slide groove is provided on the slide rail 10. The end face shape of one end of the slide rod 11 is the same as the T-shaped slide groove. One end of the slide rod 11 is slidably installed on the slide rail 10 through the T-shaped slide groove.

[0035] Reference Figure 2 and Figure 3 The clamping assembly includes a threaded rod 16 rotatably mounted between the two connecting plates 13, a through slot provided on the mounting plate 14, a nut plate 17 fixedly mounted between the two threaded rods 16, and a clamping plate 18 fixedly mounted at the lower ends of the two nut plates 17. The lower ends of the nut plates 17 pass through the through slots and are fixedly connected to the clamping plates 18. The driving assembly includes a driving gear 19 fixedly mounted at both ends of the threaded rod 16, and a tooth plate 20 fixedly mounted on the side wall of the detection frame 7. The length of the tooth plate 20 is equal to the length of the slide rail 10. The driving gear 19 meshes with the corresponding tooth plate 20.

[0036] Specifically, the injection molded product is a battery box, which is installed in the engine compartment of the car. Drive motors (not shown in the figure) are installed on the side walls of the front transmission frame 2 and the rear transmission frame 3. The drive motors are electrically connected to the optical sensor 15. When the midpoint of the injection molded product moves to just above the midpoint of the support plate 9, the optical sensor 15 receives the information and controls the two drive motors to stop working. At this time, the conveyor belts 4 on the front transmission frame 2 and the rear transmission frame 3 stop moving. At this time, the injection molded product is located just above the support plate 9 (at the same time, the injection molded product is located between the front transmission frame 2 and the rear transmission frame 3). The two limit rods 6 are used to limit the injection molded product in the horizontal direction. Because the distance between the two limiting rods 6 is equal to the width of the injection molded product, when the injection molded product moves on the front transmission frame 2, the two limiting rods 6 limit the injection molded product in the horizontal direction, and the two clamping plates 18 can limit the vertical and horizontal directions of the injection molded product to prevent the injection molded product from being offset due to external factors such as vibration during the upward movement of the injection molded product, which limits the subsequent detection effect, and the two clamping plates 18 move synchronously in the direction of approaching each other, so that when the two clamping plates 18 clamp the injection molded product, the midpoint of the injection molded product must be located at the midpoint of the two clamping plates 18. Both nut plates 17 are provided with thread grooves, and are threadedly installed on the threaded rod 16 through the thread grooves, and the two thread grooves are in opposite directions, so that when the threaded rod 16 rotates, the two nut plates 17 move in opposite directions, and then when the threaded rod 16 rotates, the two clamping plates 18 move in the direction of approaching each other or moving away from each other. The function of the through slot is to limit the nut plate 17 to prevent the threaded rod 16 from rotating synchronously with the nut plate 17 . Through the through slot, when the threaded rod 16 rotates, the nut plate 17 moves horizontally along the threaded rod 16 .

[0037] During use, the finished injection molded product is placed on the conveyor belt 4 on the front conveyor frame 2 in a specific state, so that the finished injection molded product moves with the conveyor belt 4 under the action of the two limit rods 6. When the midpoint of the finished injection molded product moves to just above the midpoint of the support plate 9, the optical sensor 15 is triggered. After receiving the signal, the optical sensor 15 turns off the two drive motors and turns on the cylinder 8. The cylinder 8 drives the support plate 9 to rise in the vertical direction through the telescopic end. When the support plate 9 moves upward, it contacts the bottom end of the finished injection molded product and drives the finished injection molded product to move upward synchronously. When the finished injection molded product moves upward, Its upper end contacts the lower end of the mounting plate 14 and drives the lifting plate 12 to move synchronously. During the upward movement of the connecting plate 13, the driving gears 19 at both ends are meshed with the toothed plates 20 to drive the driving gears 19 to rotate and then drive the threaded rod 16 to rotate synchronously. When the threaded rod 16 rotates, the two nut plates 17 at its upper ends approach each other, so that when the injection molded product rises to the highest point, the two clamping plates 18 just clamp and fix the two ends of the injection molded product. At this time, the midpoint of the injection molded product is at the midpoint of the two clamping plates 18, completing the positioning and fixation of the injection molded product before inspection.

[0038] Example 2, reference Figure 5 as well as Figure 7-Figure 9 , which is the second embodiment of the present invention. This embodiment is different from the first embodiment in that: the detection component includes a detection machine table 21 fixedly installed on the upper end of the detection frame 7, two mounting seats 22 fixedly installed on the side walls on both sides of the detection frame 7, horizontal grooves 23 opened on both sides of the mounting seats 22, a sliding frame 24 slidably installed between the two corresponding horizontal grooves 23, a detection plate 25 fixedly installed on the sliding frame 24, and a plurality of detection probes 26 fixedly installed on the detection plate 25. The plurality of detection probes 26 are all connected to the detection machine table 21 with wires, a linkage component is installed between the detection plate 25 and the lifting plate 12, and a product separation component is installed on the rear transmission frame 3.

[0039] Specifically, the detection component is used to detect the iron-deficient parts of the injection molded product (in the production process of the injection molded product, five kinds of iron parts are usually placed in the installation position of the prefabricated tooling for nine times, and then the injection molding is cooled), and the detection probe 26 has nine, which are respectively used to detect each iron part in the injection molded product. When the iron parts in the injection molded product are normal values, the nine lights on the display screen on the detection machine 21 are all green lights. When there is a red light in the nine lights, it is proved that there is a problem of iron-deficient parts in the injection molded product, and the staff needs to collect it additionally and rework it. The detection probe 26 is used to be inserted into both sides of the injection molded product, and detects its interior, and then the test result is transmitted to the detection machine 21.

[0040] Reference Figure 2 and Figure 3 The linkage assembly includes a hinge block 27 fixedly mounted on the side wall of the detection plate 25, a rotating shaft 28 rotatably mounted on the hinge block 27, two connecting strips 29 fixedly mounted on the side walls on both sides of the lifting plate 12, a hinge block 30 fixedly mounted on the lower end of the connecting strip 29, a rotating shaft 31 rotatably mounted on the hinge block 30, and a connecting rod 32 rotatably arranged between the corresponding rotating shaft 28 and the rotating shaft 31.

[0041] Specifically, the function of the linkage component is: while positioning the injection molded product at the specified position through the positioning component, the detection probes 26 on both sides can be just inserted into the two sides of the injection molded product to detect the injection molded product. No manual operation and installation are required throughout the process, and the injection molded product can be automatically and quickly positioned and detected. After the detection is completed, with the resetting of the telescopic end of the cylinder 8, the injection molded product after the detection can return to between the two conveyor belts 4. When the cylinder 8 is reset, the optical sensor 15 controls the two drive motors to restart, so that the two conveyor belts 4 move again, and the next injection molded product is transmitted to the detection frame 7. At the same time, the detected injection molded product is transmitted through the rear transmission frame 3, realizing a fully automated process, greatly reducing the manual workload and improving the detection efficiency of the device.

[0042] During use, when the lifting plate 12 moves upward, the connecting strips 29 on both sides move synchronously, and then generate tension on the detection plate 25 and the sliding frame 24 through the connecting rod 32, so that the sliding frame 24 slides along the horizontal groove 23 under the action of the tension, and then the sliding frames 24 on both sides move closer to each other. When the injection molded product is just clamped by the two clamping plates 18, the detection probes 26 on both sides are just inserted into the holes on both sides of the injection molded product. At this time, the detection probes 26 detect the injection molded product. After the detection is completed, the detection machine 21 controls the telescopic end of the cylinder 8 to reset, and then drives the support plate 9 to reset, so that the injection molded product is located directly above the conveyor belt 4 again.

[0043] The remaining structures are the same as those of Example 1.

[0044] Example 3, reference Figure 1 as well as Fig.10 , which is the third embodiment of the present invention, and this embodiment is different from the second embodiment in that: the product separation assembly includes a socket plate 33 fixedly mounted between the side walls on both sides of the rear transmission frame 3, a servo motor 34 fixedly mounted on the socket plate 33, a rotating rod 35 fixedly mounted on the driving end of the servo motor 34, and a product separation plate 36 fixedly mounted on the outer wall of the rotating rod 35. The servo motor 34 is electrically connected to the detection machine 21.

[0045] Specifically, the servo motor 34 transmits different signals through the detection machine 21, thereby controlling the direction of the rotating rod 35. When the detection machine 21 detects an injection molded product with iron-deficient parts, the servo motor 34 reverses after receiving the signal from the detection machine 21, thereby driving the sorting plate 36 on the rotating rod 35 to reverse. While the sorting plate 36 reverses, one end of the sorting plate 36 contacts one end of the rear transport frame 3, so that the injection molded product is transported to the other side. When the detection machine 21 detects that the injection molded product is qualified, the detection machine 21 transmits a signal to the servo motor 34, so that the servo motor 34 drives the sorting plate 36 to rotate forward through the rotating rod 35, thereby making the normal injection molded product and the unqualified injection molded product take different routes, thereby achieving different collection of the two, which is convenient for subsequent processing.

[0046] The remaining structure is the same as that of Example 2.

[0047] In summary, the working principle of the present invention is as follows: the finished injection molded product is placed on the conveyor belt 4 on the front conveyor frame 2 in a specific state, so that the finished injection molded product moves along the conveyor belt 4 under the action of the two limit rods 6. When the midpoint of the finished injection molded product moves to just above the midpoint of the support plate 9, the optical sensor 15 is triggered. After receiving the signal, the optical sensor 15 turns off the two drive motors and turns on the cylinder 8. The cylinder 8 drives the support plate 9 to rise in the vertical direction through the telescopic end. When the support plate 9 moves upward, it contacts the bottom end of the finished injection molded product and drives the finished injection molded product to move upward synchronously. When the injection molded product moves upward, the optical sensor 15 turns on the cylinder 8. When the finished product moves upward, its upper end contacts the lower end of the mounting plate 14 and drives the lifting plate 12 to move synchronously. During the upward movement of the connecting plate 13, the driving gears 19 at both ends are meshed with the toothed plates 20 to drive the driving gears 19 to rotate and then drive the threaded rod 16 to rotate synchronously. When the threaded rod 16 rotates, the two nut plates 17 at its upper ends approach each other, so that when the injection molded product rises to the highest point, the two clamping plates 18 just clamp and fix the two ends of the injection molded product. At this time, the midpoint of the injection molded product is at the midpoint of the two clamping plates 18, completing the positioning and fixation of the injection molded product before inspection.

[0048] When the lifting plate 12 moves upward, the connecting strips 29 on both sides move synchronously, and then generate tension on the detection plate 25 and the sliding frame 24 through the connecting rod 32, so that the sliding frame 24 slides along the horizontal groove 23 under the action of the tension, and then the sliding frames 24 on both sides move closer to each other. When the injection molded product is just clamped by the two clamping plates 18, the detection probes 26 on both sides are just inserted into the holes on both sides of the injection molded product. At this time, the detection probes 26 detect the injection molded product. After the detection is completed, the detection machine 21 controls the telescopic end of the cylinder 8 to reset, and then drives the support plate 9 to reset, so that the injection molded product is located directly above the conveyor belt 4 again.

[0049] When the inspection machine 21 detects an injection molded product with iron-deficient parts, the servo motor 34 reverses after receiving the signal from the inspection machine 21, thereby driving the sorting plate 36 on the rotating rod 35 to reverse. While the sorting plate 36 reverses, one end of the sorting plate 36 contacts one end of the rear transport frame 3, so that the injection molded product is transported to the other side. When the inspection machine 21 detects that the injection molded product is qualified, the inspection machine 21 transmits a signal to the servo motor 34, so that the servo motor 34 drives the sorting plate 36 to rotate forward through the rotating rod 35, thereby making the normal injection molded product and the unqualified injection molded product take different routes, thereby achieving different collection of the two, which is convenient for subsequent processing.
