[0043] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0044] like Figure 5 As shown, a car luggage rack decorative cover buckle detection and assembly equipment provided by the present invention includes a protective mechanism 1, two sets of press-fitting mechanisms 2, a buckle positioning detection installation mechanism 3, and a control mechanism 4; the protective mechanism 1 is installed above the press-fitting mechanism 2, the press-fitting mechanism 2 is installed on the buckle positioning detection installation mechanism 3, and the control mechanism 4 is below the positioning detection installation mechanism 3. The control mechanism 4 includes a support frame 4-1, and the support frame 4-1 adopts a frame structure. A guard plate 4-2 is provided on the frame structure. Electrical control cabinets 4-5 are provided on both sides of the control mechanism 4, and an air source processing double-joint 4-3 and a solenoid valve 4-4 are provided in the electrical control cabinet 4-5.

[0045] like Figure 6 As shown, the protection mechanism 1 includes a protection mechanism body 1-1, and the protection mechanism 1 is fixed on the workbench panel 3-1 through fixing plates 1-6 on both sides of the protection mechanism body 1-1. Wire meshes 1-2 and gratings 1-5 are provided on both sides of the protection mechanism body 1-1. The top of the protection mechanism body 1-1 is provided with a lighting lamp 1-3, a signboard 1-4 and a buzzer 1-7. The protection mechanism 1 is fixed on the workbench panel 3-1, taking into account both safety and aesthetics, and the lighting facilities facilitate the operation of on-site personnel.

[0046] like Figure 7As shown, the buckle positioning detection installation mechanism 3 is an integrated module, which integrates the positioning, detection and installation of the buckle, and specifically includes a workbench panel 3-1. The workbench panel 3-1 is provided with two rows of operable detection and installation devices, and each row of detection and installation devices includes six groups of positioning devices arranged in parallel. The positioning device includes a metal buckle positioning block 3-4 and an auxiliary positioning block 3-6 of a U-shaped structure. The metal buckle positioning block 3-4 is clamped in the groove of the auxiliary positioning block 3-6 of the U-shaped structure. The auxiliary positioning block 3-6 can assist in positioning, so that the decorative cover of the car luggage rack is fully positioned, ensuring that subsequent operations are accurate and without misalignment. The auxiliary positioning block 3-6 is connected to the support block 3-8 through the fixing plate 3-7, and the support block 3-8 is installed on the workbench panel 3-1; the metal buckle positioning block 3-4 is installed with a proximity sensor 3-3, and the proximity sensor 3-3 is connected to the buzzer 1-7 through a signal. The proximity sensor 3-3 is used to detect the position of the metal buckle in the card slot of the metal buckle positioning block 3-4. Furthermore, the proximity sensor 3-3 used in the present invention is a highly sensitive and high-precision metal induction proximity switch, which is hidden and embedded in the installation and fixed with threads, and is firm, reliable and stable in operation.

[0047] like Figure 8 As shown, two groups of press-fitting mechanisms 2 are respectively installed above the buckle positioning detection installation mechanism 3; the press-fitting mechanism 2 includes a support cross bar 2-1, and the support cross bar 2-1 is made of aluminum alloy profile, which is easy to process and has low cost. The support cross bar 2-1 is firmly and reliably fixed on the workbench panel 3-1 through three groups of L-shaped connecting brackets 2-2. Six groups of automatic pneumatic control devices are arranged on the support cross bar 2-1, and the six groups of automatic pneumatic control devices are arranged above the six groups of positioning devices on the workbench panel 3-1, and the six groups of automatic pneumatic control devices correspond to the six groups of positioning devices.

[0048] The automatic pneumatic control device comprises a cylinder 2-3, which is arranged on the supporting cross bar 2-1. The bottom of the cylinder 2-3 is connected to a pressure head 2-4, which is arranged above the positioning device.

[0049] Furthermore, two groups of relatively arranged profiling blocks 3-2 are provided on the workbench panel 3-1 (the specific adjustment can be made according to the actual product configuration), and the six groups of parallel positioning devices are arranged on six parallel positioning devices, and the distance between the two groups of profiling blocks 3-2 is slightly larger than the length of the automobile luggage rack decorative cover.

[0050] Furthermore, spring return guide mechanisms 3-5 are provided at both ends of the top of the U-shaped auxiliary positioning block 3-6, the bottom of the spring return guide mechanism 3-5 passes through the auxiliary positioning block 3-6 and is connected to the fixed plate 3-7, and the top spring of the spring return guide mechanism 3-5 extends out from the top of the auxiliary positioning block 3-6. The spring return guide mechanism 3-5 is used to release the spring rebound of the spring return guide mechanism 3-5 after the air pressure device leaves the product after press-fitting, and the spring recovers and pushes the product up, so that the on-site operator can easily take away the product.

[0051] Furthermore, a storage box 3-10, a manifold 3-11 and an electrical control button 3-9 are installed on the workbench panel 3-4, and the electrical control button 3-9 is used to control the on and off of the automatic pneumatic control device. When the proximity sensor 3-3 detects that the metal buckle of the metal buckle positioning block 3-4 of the positioning device is inserted, the personnel are away from the action range of the cylinder, the grating 1-5 releases the alarm, and then the electrical control button 3-9 is operated, the air circuit system can respond, that is, the electrical control system responds, and then the cylinder can move.

[0052] Furthermore, in order to facilitate the movement of the equipment, adjustable casters 4-6 are provided at the bottom of the support frame 4-1.

[0053] The specific steps of using the device of the present invention include:

[0054] S1: First, place the metal buckles one by one in the positioning slots of the metal buckle positioning blocks 3-4 of the six groups of positioning devices;

[0055] S2: The six detection mechanisms on the metal buckle positioning blocks 3-4 of the six positioning devices, namely the proximity sensor 3-3, sense whether the metal buckle exists. When the proximity sensor 3-3 detects that the metal buckle is in the correct position and not skewed, the device releases the buzzer 1-7 alarm;

[0056] When the proximity sensor 3-3 detects that there is a missing metal buckle on the positioning device, the proximity sensor 3-3 connects the buzzer 1-7 to alarm through the signal, and the device cannot proceed to the next step. The operator checks the position corresponding to the alarm and reinserts the metal buckle. The alarm is lifted and the device can continue to operate;

[0057] S3: Place the car luggage rack decorative cover on top of the pre-placed metal buckle according to its shape, and place the two ends of the car luggage rack decorative cover between the two groups of contoured positioning 3-2. When the car luggage rack decoration and the six auxiliary positioning blocks 3-6 are fully positioned without deformation and abnormality, press the electrical control button 3-9, and the six groups of cylinders 2-3 of the press-fitting mechanism 2 are pressed down at the same time. The six groups of pressing heads 2-4 corresponding to the six groups of cylinders 2-3 press down with the product, and the car luggage rack decorative cover can be pressed into the metal buckle below. The car luggage rack decorative cover is hooked by the structure of the metal buckle itself, so that the two are firm and reliable, and cannot fall off easily, and the press-fitting can be completed;

[0058] S4: Finally, the spring return guide pillar mechanism 3-5 pushes the product up through its own spring rebound force. The on-site operator takes away the product.

[0059] Through the above operation, the present invention realizes the buckle assembly of the luggage rack decorative cover in an automated manner, thereby making the plastic parts and the metal buckles of the automobile luggage rack decorative cover firm and reliable, and unable to fall off easily, and the press-fitting can be completed.

[0060] The protective mechanism provided by the present invention is arranged above the pressing mechanism, and is fixed on the workbench panel together with the buckle positioning detection installation mechanism, so as to protect the safety of the on-site operators in all directions. The buckle positioning detection installation mechanism integrates the metal buckle positioning, detection and installation mechanism. The pressing mechanism is mainly composed of a cylinder and a pressure head, which is fixed on the workbench panel, and the control mechanism is below. The control mechanism is provided with an electrical control cabinet, an air source treatment two-piece, a solenoid valve and casters. The electrical control cabinet is arranged under the workbench and is connected to control the cylinders on each mechanism. The air source treatment component is placed under the workbench, fixed under the workbench panel, and is immersed in the installation, which is both protective and easy to observe, and takes into account the appearance. The casters are convenient for on-site transportation, which is convenient and fast. The present invention improves labor production efficiency, reduces manufacturing costs, reduces labor intensity, and ensures safe production. In addition, the present invention adopts two rows of operable detection devices, and the two rows of detection devices are symmetrical structures, which can be used for product left and right parts detection and assembly without interfering with each other. By fixing the proximity sensor on the metal buckle positioning block, the detection device can realize both positioning and detection functions, and then the profiling block and the auxiliary positioning block are set to complement each other and fully position. At the same time, the equipment is shared on the left and right, the structural design is compact, the space is fully utilized, the layout is reasonable, the cost is optimal, and the efficiency can be maximized. The present invention fully considers the pain points of the traditional operation method, that is, manual assembly, and overcomes the long-standing problem that the manual assembly method cannot prevent leakage and fool-proof, cannot guarantee product quality, and has great risks in delivery. The present invention is movable and fixable, flexible, convenient to use, efficient and stable.
