Furthermore, features defined with "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0030] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0031] like Figures 1 to 9 As shown, the workpiece lifting device of this utility model includes: a lifting drive assembly 1, a lifting seat 2, an elastic column 3, and a cover plate 4. The lifting seat 2 is installed on the lifting drive assembly 1 and is used to lift the workpiece. The elastic column 3 is installed on the lifting drive assembly 1, and the upper end of the elastic column 3 protrudes from the lifting seat 2. The elastic column 3 is used to lift the carrier 100 that holds the workpiece. The cover plate 4 is installed on the conveying track 200 and is used to limit the lifting height of the carrier 100.

[0032] It should be noted that, through structural improvements, this utility model allows for the following operation: when the carrier 100 is transported directly above the lifting device, the lifting drive assembly 1 drives the lifting seat 2 and the elastic column 3 to rise synchronously. After the elastic column 3 contacts the lower surface of the carrier 100, the lifting drive assembly 1 continues to drive the elastic column 3 and the lifting seat 2 to rise. At this time, the carrier 100 is lifted upwards. When it reaches a certain height, the carrier 100 cannot continue to rise due to the restriction of the cover plate 4. At this time, the lifting drive assembly 1 continues to drive the lifting seat 2 to rise, lifting the workpiece inside the carrier 100 upwards. During this process, the elastic column 3 is in a compressed state.

[0033] That is, the jacking process of the utility model is that the carrier 100 is first jacked upward, then the workpiece is jacked upward from the carrier 100, and when jacking is completed, the lower half of the workpiece is positioned by the carrier 100 and the upper half is positioned by the cover plate 4, so that the position accuracy of the workpiece during the dispensing operation can be ensured.

[0034] Specifically, the jacking seat 2 comprises a jacking bottom plate 21, a plurality of jacking columns 22 and a positioning column 23, the jacking columns 22 are fixedly connected with the jacking bottom plate 21, the distribution positions of the plurality of jacking columns 22 correspond to the positions of the plurality of workpieces on the carrier 100 one by one, and the positioning column 23 is installed on the jacking bottom plate 21. The carrier 100 is provided with positioning holes 101 matched with the positioning column 23. When the jacking drive assembly 1 drives the jacking seat 2 to move upward, the positioning column 23 is inserted into the positioning holes 101 on the carrier 100, so that the carrier 100 is positioned and the position deviation of the carrier 100 during jacking is prevented. The carrier 100 is provided with first through holes 102 corresponding to the jacking columns 22 one by one. For example, the carrier 100 comprises a base plate 103 and a plurality of bearing pieces 104, the plurality of bearing pieces 104 are installed in parallel on the base plate 103, and the bearing pieces 104 are provided with a plurality of containing positions 105 for containing workpieces. The first through holes 102 are arranged on the base plate 103 and correspond to and communicate with the containing positions 105. When the jacking drive assembly 1 drives the jacking seat 2 to move upward, the jacking columns 22 can be inserted into the first through holes 102 and can jacking the workpieces in the containing positions 105 upward along with the upward movement of the jacking seat 2.

[0035] Specifically, the cover plate 4 is provided with a plurality of second through holes 41, the positions of the second through holes 41 correspond to the workpieces on the carrier 100 one by one. The edge of the second through hole 41 is provided with a limiting portion 411. The cover plate 4 is fixed on the conveying track 200, when the carrier 100 is jacked to a certain height (i.e. when the upper surface of the carrier 100 contacts the lower surface of the cover plate 4), the carrier 100 stops moving upward. At this time, when the jacking drive assembly 1 continues to jacking the jacking seat 2, the jacking columns 22 can jacking the workpieces through the first through holes 102. When the upper surface of the workpiece contacts the limiting portion 411, the workpiece stops moving upward. At this time, the upper half of the workpiece is limited by the cover plate 4 and the lower half is limited by the carrier 100, so that the position accuracy of the workpiece during pad printing and dispensing can be ensured, thereby improving the accuracy of dispensing operation.

[0036] The jacking driving assembly 1 comprises a base 11, a jacking cylinder 12, a jacking plate 13 and a bearing plate 14, the jacking cylinder 12 is installed on the base 11, the jacking plate 13 is in sliding connection with the base 11, the bearing plate 14 is in fixed connection with the upper end of the jacking plate 13, the telescopic end of the jacking cylinder 12 is connected with the jacking plate 13, and the jacking seat 2 is installed on the bearing plate 14. When the telescopic end of the jacking cylinder 12 extends upward, the jacking plate 13 and the bearing plate 14 can be driven to move synchronously, and the jacking of the jacking seat 2 is realized.

[0037] For example, the elastic column 3 comprises a compression spring 31 and a pin 32, the compression spring 31 is sleeved on the pin 32, the pin 32 is installed on the bearing plate 14, and the upper end of the pin 32 can penetrate through the jacking seat 2.

The lower surface of the bearing plate 14 is provided with a mounting block 142, and the pin 32 penetrates through the mounting block 142, the second through hole 141 and the first through hole 212 in sequence from bottom to top. The lower end of the compression spring 31 is limited by the stepped surface in the mounting block 142, and the upper end is limited by the pin 32. When the upper end of the elastic column 3 is pressed against the carrier 100 and the jacking seat 2 continues to move upward, the pin 32 will be pressed downward, at this time, the compression spring 31 is compressed. When the jacking seat 2 is lowered and reset, the pin 32 can be reset upward under the elastic force of the compression spring 31. For example, the height of the elastic column 3 protruding from the jacking bottom plate 21 is flush with the height of the jacking column 22 in the natural state.
