Description

Technical Field

[0001] This utility model relates to the field of testing equipment technology, specifically a testing device for injection molding of bag shells. Background Technology

[0002] With the widespread application of injection molding technology for luggage shells, consistent product appearance quality has become a key competitive advantage for enterprises. Traditional manual sampling inspection is inefficient, has a high rate of missed inspections, and is difficult to match the pace of high-speed production lines. Existing online inspection devices mostly rely on fixed vision systems, which suffer from problems such as inaccurate shell positioning and image acquisition jitter. In particular, they lack rapid positioning capabilities, resulting in inspection accuracy being greatly affected by transport interference.

[0003] Therefore, there is an urgent need for a detection device that integrates automatic blocking positioning and elastic limiting mechanisms to achieve stable and accurate positioning of the shell, improve the reliability of image acquisition, and meet the requirements for efficient and high-precision online detection of injection molded shells.

[0014] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. However, the specific implementation methods and embodiments described below are for illustrative purposes only and are not intended to limit the present invention.

[0015] In the description of this utility model, it should be understood that the terms "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the appendix. Figure 1The directions or positional relationships shown are for the purpose of describing this utility model only, and are not intended to indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0016] In the description of this application, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated.

[0017] To solve the above technical problems, such as Figure 1-2 As shown, this utility model designs a bag shell injection molding processing inspection device, including a workbench 1 and a horizontal conveyor line 2. The horizontal conveyor line 2 is set horizontally on the workbench 1. A bracket 3 is provided on one side of the horizontal conveyor line 2. An image acquisition device 4 is installed on the bracket 3. The information acquisition end of the image acquisition device 4 faces vertically downward toward the horizontal conveyor line 2. The horizontal conveyor line 2 is used to transmit a pallet 5 in the front-to-back direction. The pallet 5 is used to place the molded shell. The horizontal conveyor line 2 is provided with corresponding front-to-back blocking positioning mechanisms and automatic limiting mechanisms in the transmission direction.

[0018] The automatic limiting mechanism includes a support plate 6, a support base 7, a limiting block 8, and a support rod 9. The support plate 6 is disposed inside the limiting frame of the horizontal conveyor line 2. The support plate 6 is provided with the support base 7, and the top of the support base 7 is provided with a storage groove. The limiting block 8 is installed in the storage groove of the support base 7 and is rotatably engaged with it through a support shaft 11. The front side of the limiting block 8 is provided with an upward triangular protrusion 10. The inner side of the support base 7 is also provided with a countersunk hole for placing the support rod 9. The support rod 9 is a telescopic rod and its top end contacts the triangular protrusion 10. A spring is sleeved on the outer side of the support rod 9. The limiting block 8 is used to make the pallet... When the pallet 5 passes through, it is unobstructed and is limited from behind after it is no longer in contact, forming a "one-way door" type limit. When the pallet 5 moves forward, the inclined surface is pressed, causing the limiting block 8 to rotate into the groove, allowing it to pass through without any obstruction. If the pallet 5 retracts, it is resisted by the triangular protrusion 10, which mechanically locks to prevent secondary displacement. The telescopic support rod 9 in the countersunk hole and the spring form a flexible rebound system, which provides both restoring force and absorbs impact, avoiding scratches on the shell and deformation of the mechanism. The entire mechanism is purely mechanically linked, requiring no additional power or sensors. It has a compact structure, low failure rate, and the triangular protrusion 10 can be quickly replaced to easily adapt to shells of different thicknesses, achieving efficient, low-consumption, and maintenance-free precise positioning.

[0019] The blocking and positioning mechanism includes a cylinder 12, a lifting block 13, and a baffle 14. The cylinder 12 is located inside the horizontal conveyor line 2. The piston rod of the cylinder 12 faces upward and is fixedly connected to the lifting block 13. The lifting block 13 is equipped with a baffle 14, which is used to block and limit the pallet 5 from the front. The cylinder 12 is hidden inside the conveyor line. When the piston rod is pushed up, the baffle 14 rises in milliseconds to form a rigid front stop. The pallet 5 is precisely stopped in one go, completely eliminating inertial sliding. After the image acquisition is completed, the cylinder 12 quickly retracts, the baffle 14 drops below the conveyor surface, and the pallet 5 is immediately released. The entire process is without manual intervention and without mechanical jamming.

[0020] In this embodiment, it is further preferred that the horizontal conveyor line 2 includes a transmission chain 15, a drive shaft 16, sprockets 17, and a drive motor 18. Two sets of transmission chains 15 are symmetrically arranged on the left and right sides and are respectively wound around the sprockets 17 on the front and rear sides. Adjacent sprockets 17 are connected by the drive shaft 16. The drive shaft 16 is driven by the drive motor 18. The double-chain symmetrical structure distributes the power evenly on both sides of the pallet 5. The pallet 5 moves by means of the transmission chain 15 through linkage components such as chain plate connecting blocks or chain buckles. There is no lateral swaying during movement, and the shell remains absolutely stable during the movement.

[0021] In this embodiment, it is further preferred that the tray 5 is provided with a groove, the shape of which is adapted to the shape of the shell, and after placement, it is surrounded by a contour that fits the shape, providing a fixed reference for the image acquisition device 4.

[0022] In this embodiment, it is further preferred that a display screen 19 is placed on the workbench 1, and the display screen 19 is electrically connected to the image acquisition device 4 to display magnified visual detection images in real time.

[0023] In this embodiment, it is further preferred that a positioning sensor 20 is installed on the inner side of the horizontal conveyor line 2 to instantly sense the pallet 5 entering the detection position in a non-contact manner. The signal triggers a closed loop with the cylinder 12 and the camera, making the overall machine operation rhythm more compact and reliable.

[0024] During operation, the bag shell is placed in the groove of the pallet 5. After the pallet 5 passes the triangular protrusion 10 of the limiting block 8, the front end of the pallet 5 triggers the positioning sensor 20. The cylinder 12 of the blocking positioning mechanism immediately lifts the baffle 14, limiting the pallet 5 forward. The limiting block 8 then limits it from the rear. At this time, the image acquisition device 4 takes a vertical downward picture of the front. After the inspection, the cylinder 12 retracts, and the pallet 5 continues to advance to the subsequent flipping station where the other side of the bag is manually flipped. Then, the other side of the bag is inspected.

[0025] The above embodiments are merely preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made by those skilled in the art based on the structure, shape, and principle of this utility model should be included within the scope of protection of this utility model.
