As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, it indicates the presence of features, steps, operations, devices, components and / or combinations thereof.

[0026] Unless otherwise specifically stated, the relative arrangement of the parts and steps described in these embodiments, numerical expressions and numerical values ​​do not limit the scope of the present invention. At the same time, it should be understood that, for ease of description, the sizes of the various parts shown in the accompanying drawings are not drawn according to the actual proportional relationship. The technology, method and equipment known to ordinary technicians in the relevant field may not be discussed in detail, but in appropriate cases, the technology, method and equipment should be regarded as a part of the authorization specification. In all examples shown and discussed here, any specific value should be interpreted as being merely exemplary, rather than as a limitation. Therefore, other examples of exemplary embodiments may have different values.

[0030] like Figure 1-4As shown, a feeding structure provided by the present invention includes a positioning clamping mechanism, a slide clamping mechanism and an electrical control unit arranged on the equipment workbench 6.

[0031] The positioning and clamping mechanism includes a positioning component 1 for placing a lighting product and positioning the lighting product once, and a pressing component 2 for pressing the lighting product on the positioning component 1 for secondary positioning. Specifically, the positioning component 1 includes a base plate 11, and a plurality of limit blocks 12 arranged on the base plate 11, the plurality of limit blocks 12 are symmetrically distributed on the left and right sides of the base plate 11, and the upper surfaces of the limit blocks 12 are adapted to the lower surface of the lighting product. The pressing components 2 are arranged in plurality and symmetrically distributed on the left and right sides of the base plate 11, and at least two pressing components 2 are arranged on each side. Specifically, the pressing component 2 includes a pressing cylinder 21 and a pressing block 22 connected to the output end of the pressing cylinder 21, the pressing block 22 can approach or move away from the lighting product under the action of the pressing cylinder 21, and the lower surface of the pressing block 22 is adapted to the upper surface of the lighting product. Such a design can ensure the stability of the positioning of the lighting product, thereby facilitating subsequent operations.

[0032] The slide clamping mechanism includes a slide assembly 3 arranged above the positioning clamping mechanism and movable forward and backward, and a plurality of clamping assemblies 4 arranged on the slide assembly 3 and movable left and right. The position arrangement of the plurality of clamping assemblies 4 matches the installation position of the loading screws on the lamp product, and is used to push and clamp the loading screws onto the lamp product. Specifically, the slide assembly 3 includes a fixing plate 31, and slide rail fixing seats 32 are respectively arranged on both sides of the fixing plate 31. A slide rail 33 that slidably cooperates with the fixing plate 31 is arranged at one end of the slide rail fixing seat 32. , and the other end is installed on the base plate 11. The fixed plate 31 can move forward and backward along the slide rail 33 under the action of the slide cylinder 34. Such a design can not only make the forward and backward movement of the fixed plate 31 more accurate, but also reduce the load on the fixed plate 31; the clamping assembly 4 includes a clamping cylinder 41, and a push block 42 connected to the clamping cylinder 41. The push block 42 can move left and right in a direction close to or away from the lamp product under the action of the clamping cylinder 41, so that the loading screws pre-placed on the lamp product can be clamped into place.

[0033] The electrical control unit includes an electrical control box 5 electrically connected to the positioning clamping mechanism and the slide clamping mechanism, and a first sensor component and a second sensor component signal-connected to the electrical control box 5. The electrical control box 5 is the core of the device. All electrical programs of the device are integrated in the electrical control box 5, which is used to trigger the clamping operation instructions for the signal input reception during the device operation. The first sensor component is used to detect whether a lighting product is placed on the positioning component 1, and transmit the detection signal to the electrical control box 5. If there is a product, the electrical program in the electrical control box 5 can be controlled to start. The purpose is to prevent no-load movement in the absence of lighting products, causing equipment alarms. The second sensor component is used to detect whether the clamping component 4 pushes the loading screw into place. Specifically, the second sensor component is installed on the clamping cylinder 41.

[0035] When the automatic clamping device for loading screws of a lamp of the present invention is working, the lamp product is first placed on the positioning component 1, and the loading screws are pre-placed in the lamp product. At this time, the first sensor component detects that the lamp product exists on the positioning component 1, and the program of the electrical control box 5 is started. The electrical control box 5 is triggered by the button 13 to drive the electrical program to start the operation instruction. The clamping cylinder 21 drives the clamping block 22 to clamp the lamp product on the positioning component 1, which can effectively prevent the lamp product from moving. At the same time, the slide cylinder 34 and the clamping cylinder 41 work, and the cooperation of the two can realize multi-directional adjustment in front, back, left and right, so as to ensure the clamping requirements of different positions, which is efficient and convenient. The display screen 61 can allow the staff to see the product quality OK or NG during the operation implementation process, so as to ensure that each product is qualified and meets the process requirements.
